Making strtok now but all other functions need +locale.h and I don’t know yet how I will be implemented. But it is already cool that we +have most of functions that should be in <string.h>!

As I have written before +it is going to be suckless ii clone. Also I started making girclib - simple C library for irc +protocol. I think it will be published as separate project, because I would like to make it +for both: client and server. I don’t yet how it will be done but we will see…

+ +

Then I thought that would be cool to have own libc, but have no knowledge how it speaks with OS. +Then I understood that on linux it is working via syscalls. So started making liblinux - +C library for linux syscalls. Using it we won’t need to use assembly a lot in our libc. Currently +write and read syscalls are done and programmer can use it if passed -I, -L and -l flags to compiler. +And it is already published! (check codeberg or tildegit)

+ +

After understanding how to create proper makefile with liblinux, I started making olibc. Currently +it has very tiny number of features. But string.h is mostly done! I don’t know when I will fill that +it will be ready enough to be published, but hope to have useful functions and test suit there till +that time.

+ +

When olibc will be done enough I am going to start making C compiler (already have some code, but it +is old and I not understand how it works, so need to be rewritten). Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

+ +

First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator +based on template (that should be placed in docs one day). Now if someone would like to add some architecture to +our emulator they won’t need to rewrite it from scratch.

+ +

I also added –system flag to yemu so architecture can be choosen more user-friendly way.

+ +

Currently in ocpu emulator only mov and add instructions are implemented. +We also added some description to commands in specifications, so it is easier to understand what it should do

Today is 10’s GRU Devlog! :)

+ +

This week i was trying to make notes to org document, to not forget something and put TODOs +there for future weeks.

+ +

First several days was the most valuable - readline support and signal handling! +This means you can use emacs-like bindings there (but i think readline also supports vi bindings, +so maybe i will add them too!)

+ +

Also we now have very minimal completion support there :), but still proper function need to be added +for that (currently only filenames completion)

+ +

Orsh also has one session history, so you don’t need to rewrite command from scratch now

+ +

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Also I started making bootloader, but for now it can only detect what CPU is (intel if x86 and amd if x86_64), +some additional instructions (msr) and if apic is avalible.

+ +

I was trying to make something with orion fs, maybe it will use pak files for initrd. Currently i am making archiver +for it, but after that i will need to understand more how vfs working and rewrite initrd to use pak files.

+ +

We now have xmpp room (gru@conference.hmm.st) and logo! Thanks to chunk for it!

+ +

I was thinking about making weekly or monthly “conferences”. We could do it via jitsi tildeverse instance or tilde.tel +(tel.tilde.org.nz) conference. I think jitsi is better, but we should try tilde.tel confernce at least once, why not? :)

  • make kernel, libs, ports and soft in different repos

    • +

  • make proper way to make “distros” on our kernel

    • +

  • make some website with mirror of ports scripts (like in Serenity OS but not in one repo with +everything and tool for searching and downloading ports from that mirror)

    • +

  • maybe (if i will work a lot on this projects) I’ll make one more account on tilde.team +for our organisation (domain name - gru.ttm.sh, is cool), but i’ll ask admins about that

    • +
+ + +

Also I think Orion need new name because i found several projects with this name :)

+ +

Some ideas about the GRU name:

+ +
    +

  • GRU rocks (or rocking) UNIX

    • +

  • GloRious UNIX

    • +

  • GloRious Union

+ +

I don’t understand very basic osdev thing so I decided to make OS on C and Asm. +Currently that can just output text (with printf arguments) on screen and serial. +Now gros is much cooler than Orion - it has input, interupts and a lot of else. +But maybe I’ll understand OSdev better. +Currently working on GDT (global descriptor table) and than will work on +interrupts and exceptions.

+ +

Of course if you can help me contact me throught email or in other ways!

It is shell written on Rust. Also, for now, other rewrites of coreutils are there.

+ +

What grsh can do for this moment: echo some variables (pwd, user, home, status of previous command using $?) and text; true, false, : - set status; pwd shows current dir, also comments and cd working, basic piping (thanks to that article and of course executing not builtin command also working.

+ +

Some grutils that I made: ls, touch, mkdir/rmdir, rm, grep, head/tail, yes, cat.

+ +

TODOs exist in grsh repo - so you can read there some of my plans.

+ +

Yesterday i have started GROS - OS on Rust! But I haven’t published code yet because it not have that minimum of funcionality that i want. Thanks for that site for teaching how to make basics - https://os.phil-opp.com

+ +

So it was first of GRU Devlog! Thanks for reading! If you want to contribute to some of that project write me an email - g1n@ttm.sh , or contact me in other ways

+GRU Devlog 10 - orsh now like proper shell and gasm +

+ +
October 03, 2021 — +G1n +
+ + +

Hooray! Today is 10’s GRU Devlog! :)

+ +

This week i was trying to make notes to org document, to not forget something and put TODOs +there for future weeks.

+ +

First several days was the most valuable - readline support and signal handling! +This means you can use emacs-like bindings there (but i think readline also supports vi bindings, +so maybe i will add them too!)

+ +

Also we now have very minimal completion support there :), but still proper function need to be added +for that (currently only filenames completion)

+ +

Orsh also has one session history, so you don’t need to rewrite command from scratch now

+ +

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining. +We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.

+ +

Hope you liked this post and you will join our XMPP muc (if you are not already there) :). +If you would like to help me, contact me via email, xmpp or irc :)

October 08, 2021 — +G1n +
+ + +

I am making this devlog a bit earlier, because I will be busy on weekends.

+ +

This week I didn’t have plan, but it seems I have done some things to yemu: added loading programs +from binary file and several instructions - TAX, TAY and NOP.

+ +

I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in +testing yemu.

+ +

I was trying to make some daily notes in Org Roam (and moved devlog notes there), but it wasn’t +very success, but I hope to do it more often :)

+ +

Also I have registered #gru channel on libera, so you can join us also on libera.chat :)

+ +

+GRU Devlog 13 - ocpu thoughts and some elecronics +

+ +
October 24, 2021 — +G1n +
+ + +

This week was very busy week at school and I had no time for programming.

+ +

But in the start of week I was thinking about making ocpu specs more Turing-complete. +I still think it is not done but maybe it will in some time (and of course more description required).

+ +

But I had time to buy some transistors and other electronics. Currently I am trying to make half-adder.

+ +

I have created tiny log page - lolcpu. I am going to post there some of my +electronic ideas, circuits and progress in doing some electronic things.

+ +

+GRU Devlog 12 - yemu, gasm and ocpu +

+ +
October 17, 2021 — +G1n +
+ + +

This week I have done several new instructions for yemu. For example all transfer instructions.

+ +

Also I have rewritten gasm to support 6502, published it and it should help me with debugging yemu. +It supports not very a lot instructions but I hope it is good start.

+ +

But I think the coolest what I did this week is ocpu proccessor specification. +Currently it is draft but i have already published it here. +I hope this specifications will be Turing complete and we will try to implement it in real world. +But firstly we need to make this specififcations complete, assembler and emulator for it.

+ +

Also smlckz’s idea was to make translator from ocpu assembler instructions to avr to emulate it on arduino!

+GRU Devlog 14 - ocpu and yemu +

+ +
October 31, 2021 — +G1n +
+ + +

This week I was working on ocpu emulator. So using it we can know if specifications can be implemented. +It helps me adding some description to it.

+ +

First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator +based on template (that should be placed in docs one day). Now if someone would like to add some architecture to +our emulator they won’t need to rewrite it from scratch.

+ +

I also added –system flag to yemu so architecture can be choosen more user-friendly way.

+ +

Currently in ocpu emulator only mov and add instructions are implemented. +We also added some description to commands in specifications, so it is easier to understand what it should do

November 14, 2021 — +G1n +
+ + +

This week i was working on one more new project - ormp. It will be terminal multiplexor. +Currently i am doing it in ncurses. For current time it is not working - can just handle input but not display it.

+ +

Also i have an idea for new projects - EGG (Extended/Exciting GRU GUI). I am planning some proj in this category - eggwm, eggterm, eggmenu and E. +E would be a new display server. We will need to have it for Orion in future. Currently i am planning to do it or on fbdev or on DRM/KMS.

+ +

Also now yemu can be compiled with different compilers, -pedantic flag was added to makefile and all errors fixed.

+ +

And now our channels are bridged via matterbridge: irc on ~chat, irc on libera and xmpp muc.

+GRU Devlog 17-18 - coreutils, EGG and ideas +

+ +
November 28, 2021 — +G1n +
+ + +

Last week I didn’t make devlog because was busy and haven’t done anything useful except +mkdir for coreutils.

+ +

This week I started from try to make something in framebuffer but currently nothing, because +I can’t even understand why my code can’t see size of my display. I think E will require making +something like Elib for easier communicating with E (but it will be in very far future…)

+GRU Devlog 19 - gic and several libs +

+ +
December 05, 2021 — +G1n +
+ + +

This week started with making gic (maybe name will be change). As I have written before +it is going to be suckless ii clone. Also I started making girclib - simple C library for irc +protocol. I think it will be published as separate project, because I would like to make it +for both: client and server. I don’t yet how it will be done but we will see…

+ +

Then I thought that would be cool to have own libc, but have no knowledge how it speaks with OS. +Then I understood that on linux it is working via syscalls. So started making liblinux - +C library for linux syscalls. Using it we won’t need to use assembly a lot in our libc. Currently +write and read syscalls are done and programmer can use it if passed -I, -L and -l flags to compiler. +And it is already published! (check codeberg or tildegit)

+ +

After understanding how to create proper makefile with liblinux, I started making olibc. Currently +it has very tiny number of features. But string.h is mostly done! I don’t know when I will fill that +it will be ready enough to be published, but hope to have useful functions and test suit there till +that time.

+ +

When olibc will be done enough I am going to start making C compiler (already have some code, but it +is old and I not understand how it works, so need to be rewritten). Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

+GRU DevLog 2 - Orion +

+ +
August 08, 2021 — +G1n +
+ + +

This week I was developing new OS - Orion.

+ +

I don’t understand very basic osdev thing so I decided to make OS on C and Asm. +Currently that can just output text (with printf arguments) on screen and serial. +Now gros is much cooler than Orion - it has input, interupts and a lot of else. +But maybe I’ll understand OSdev better. +Currently working on GDT (global descriptor table) and than will work on +interrupts and exceptions.

+ +

Of course if you can help me contact me throught email or in other ways!

+GRU Devlog 20 - olibc +

+ +
December 12, 2021 — +G1n +
+ + +

This week I was making olibc. I was implementing <string.h>. Also I was fixing liblinux to +be able to include it without need to use full path in #include. I had several other issues +with it and also fixed them.

+ +

My current goal is to implement <string.h> and after that I am planning to publish it. +Currently most of funcs are implemented. Making strtok now but all other functions need +locale.h and I don’t know yet how I will be implemented. But it is already cool that we +have most of functions that should be in <string.h>!

+ +

Also we now have gru webpage on codeberg! Maybe next week I +will move all devlogs to gru webpage so it will be easier to move.

+GRU DevLog 3 - Orion and dreams about GRU software future +

+ +
August 15, 2021 — +G1n +
+ + +

This week I was trying to make interrupts, paging and other memory things working in Orion. +I found this guide and tried to follow it without rewriting the whole project: +http://www.jamesmolloy.co.uk/index.html

+ +

For now only Global Descriptor Table maybe working.

+ +

My current goals/dreams:

+ +
    +

  • make filesystem (the coolest would be make Ext2 driver)

    • +

  • build GCC hosted compiler (this will help GCC understand our OS better)

    • +
+ + +

My very future dreams:

+ +
    +

  • make kernel, libs, ports and soft in different repos

    • +

  • make proper way to make “distros” on our kernel

    • +

  • make some website with mirror of ports scripts (like in Serenity OS but not in one repo with +everything and tool for searching and downloading ports from that mirror)

    • +

  • maybe (if i will work a lot on this projects) I’ll make one more account on tilde.team +for our organisation (domain name - gru.ttm.sh, is cool), but i’ll ask admins about that

    • +
+ + +

Also I think Orion need new name because i found several projects with this name :)

+ +

Some ideas about the GRU name:

+ +
    +

  • GRU rocks (or rocking) UNIX

    • +

  • GloRious UNIX

    • +

  • GloRious Union

    • +
+ + +

If you can help me or have some ideas (name/names or anything else) contact me via email +or any other type of contact (irc: g1n on tilde.chat, xmpp: g1n@hmm.st)

August 22, 2021 — +G1n +

In first days of this week I thought it will be not very productive. +But I was wrong.

+ +

We now have webpage and organizations on tildegit/codeberg:

+ +

https://g1n.ttm.sh/gru/

+ +

Also I am working on some new projects:

+ +
    +

  • orcc - GRU/Orion Compilers Collection (but currently I am working only on lexer so it is not published yet)

    • +

  • gasm - GRU assembler (maybe will be part of GRU binutils. Also not published yet)

    • +

  • hexutils - I think hexdump, xxd and some other utils will be in this project

    • +
+ + +

Also I tryed to advertize GRU on ~chat, some users liked us, +so maybe soon someone will help me with all this.

+ +

And of course if you can help me please contact me in someway! :)

+GRU Devlog 5 - First contribution from other person, coreutils and gxt (tui text editor) +

+ +
August 29, 2021 — +G1n +
+ + +

This week I had a lot of new ideas. But I think we have to work on something that +have already been started. +Also we now have one more coreutils rewrite +(now on C to more easily port it to Orion in future).

+ +

Also i have started working on some +projects that is not ready to be published yet. One of them is gxt - tui text editor.

+ +

Currently it can only move cursor and display files. But I think I’ll publish it next week +when editing will be working.

+ +

Bad news is that my school lessons will start next week so maybe this devlogs won’t be +published every week, because of not enough work done. But I don’t know, maybe I’ll have +enough time.

+ +

Also good news - we have first contribution on codeberg to grsh. I didn’t know this person +(because he is not from tildeverse :) ), so it is cool!

+ +

Hope you liked this devlog! If you can somehow help us, please contribute to our projects +on tildegit/codeberg and/or message me in someway :)

This week I have published gxt, but it currently works as more (only down scrolling). +Also it has a lot of of runtime error (Segmentation fault and others).

+ +

I have started working on yemu - Yet another EMUlator. It currently supports only 6502 +proccessor with tiny number of instructions (LDA, LDX and LDY)

Today we have fixed interrupts in Orion and now I can implement timer, paging, keyboard +and a lot of other things (thanks to quinn and smlckz from tilde.chat)

+GRU Devlog 7 - keyboard, paging and WIP initrd in Orion +

+ +
September 12, 2021 — +G1n +
+ + +

This week I was improving Orion. First I made keyboard working, next day paging! +Also I have added several new LibC functions. +Today I have made scrolling working.

+ +

Last few days I was trying to make initrd working +(this required heap implementing so I also did that but I don’t know if it works correctly). +Currently it can only output /dev directory.

+ +

But I made something wrong with %x in printf and it can display weird chars first +and then contents of files!

+ +
September 19, 2021 — +G1n +
+ + +

This week I have published initrd, but it is not working as expected.

+ +

Also I have started one more project - orsh. It is one more shell, but now in C. +Maybe it will be easier to port to Orion. It already supports ; but they are working a bit weird.

+ +

Also in orsh you can work with environment variables. +From today’s morning I am trying to replace bash with it, but still a lot need to be done.

+GRU Devlog 9 - orsh, orion, bootloader, GRU xmpp room and logo +

+ +
September 26, 2021 — +G1n +
+ + +

This week I didn’t commited a lot, but started some new projects. +I made orsh signal handling working (so it won’t exit on ^C) and homedir “handling” +(can replace homedir in prompt with ~, and you can use ‘cd ~’ or just ‘cd’ to change +dir to homedir)

+ +

Also I started making bootloader, but for now it can only detect what CPU is (intel if x86 and amd if x86_64), +some additional instructions (msr) and if apic is avalible.

+ +

I was trying to make something with orion fs, maybe it will use pak files for initrd. Currently i am making archiver +for it, but after that i will need to understand more how vfs working and rewrite initrd to use pak files.

+ +

We now have xmpp room (gru@conference.hmm.st) and logo! Thanks to chunk for it!

+ +

I was thinking about making weekly or monthly “conferences”. We could do it via jitsi tildeverse instance or tilde.tel +(tel.tilde.org.nz) conference. I think jitsi is better, but we should try tilde.tel confernce at least once, why not? :)

+ +

+GRU DevLog Week 0 - grsh, grutils and start of gros +

+ +
July 25, 2021 — +G1n +
+ + +

So I have started new project this week - grsh! It is shell written on Rust. Also, for now, other rewrites of coreutils are there.

+ +

What grsh can do for this moment: echo some variables (pwd, user, home, status of previous command using $?) and text; true, false, : - set status; pwd shows current dir, also comments and cd working, basic piping (thanks to that article and of course executing not builtin command also working.

+ +

Some grutils that I made: ls, touch, mkdir/rmdir, rm, grep, head/tail, yes, cat.

+ +

TODOs exist in grsh repo - so you can read there some of my plans.

+ +

Yesterday i have started GROS - OS on Rust! But I haven’t published code yet because it not have that minimum of funcionality that i want. Thanks for that site for teaching how to make basics - https://os.phil-opp.com

+ +

So it was first of GRU Devlog! Thanks for reading! If you want to contribute to some of that project write me an email - g1n@ttm.sh , or contact me in other ways

+GRU Devlog 20 - olibc +

+ +
December 12, 2021 — +G1n +
+ + +

This week I was making olibc. I was implementing <string.h>. Also I was fixing liblinux to +be able to include it without need to use full path in #include. I had several other issues +with it and also fixed them.

+ +

My current goal is to implement <string.h> and after that I am planning to publish it. +Currently most of funcs are implemented. Making strtok now but all other functions need +locale.h and I don’t know yet how I will be implemented. But it is already cool that we +have most of functions that should be in <string.h>!

+ +

Also we now have gru webpage on codeberg! Maybe next week I +will move all devlogs to gru webpage so it will be easier to move.

+ +

+GRU Devlog 19 - gic and several libs +

+ +
December 05, 2021 — +G1n +
+ + +

This week started with making gic (maybe name will be change). As I have written before +it is going to be suckless ii clone. Also I started making girclib - simple C library for irc +protocol. I think it will be published as separate project, because I would like to make it +for both: client and server. I don’t yet how it will be done but we will see…

+ +

Then I thought that would be cool to have own libc, but have no knowledge how it speaks with OS. +Then I understood that on linux it is working via syscalls. So started making liblinux - +C library for linux syscalls. Using it we won’t need to use assembly a lot in our libc. Currently +write and read syscalls are done and programmer can use it if passed -I, -L and -l flags to compiler. +And it is already published! (check codeberg or tildegit)

+ +

After understanding how to create proper makefile with liblinux, I started making olibc. Currently +it has very tiny number of features. But string.h is mostly done! I don’t know when I will fill that +it will be ready enough to be published, but hope to have useful functions and test suit there till +that time.

+ +

When olibc will be done enough I am going to start making C compiler (already have some code, but it +is old and I not understand how it works, so need to be rewritten). Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

+GRU Devlog 17-18 - coreutils, EGG and ideas +

+ +
November 28, 2021 — +G1n +
+ + +

Last week I didn’t make devlog because was busy and haven’t done anything useful except +mkdir for coreutils.

+ +

This week I started from try to make something in framebuffer but currently nothing, because +I can’t even understand why my code can’t see size of my display. I think E will require making +something like Elib for easier communicating with E (but it will be in very far future…)

+ +

Then I made echo and very simple ls for coreutils. I am going to add more flags to ls next week. +This week I also have made simple irc bot in python, so I will try to make simple clone of suckless ii +on C (i think name gic is now really good so if you have ideas please suggest them to me). +Currently I don’t reallly understand how to work with sockets but I will try to do something.

+GRU Devlog 16 - ormp and EGG +

+ +
November 14, 2021 — +G1n +
+ + +

This week i was working on one more new project - ormp. It will be terminal multiplexor. +Currently i am doing it in ncurses. For current time it is not working - can just handle input but not display it.

+ +

Also i have an idea for new projects - EGG (Extended/Exciting GRU GUI). I am planning some proj in this category - eggwm, eggterm, eggmenu and E. +E would be a new display server. We will need to have it for Orion in future. Currently i am planning to do it or on fbdev or on DRM/KMS.

+ +

Also now yemu can be compiled with different compilers, -pedantic flag was added to makefile and all errors fixed.

+ +

And now our channels are bridged via matterbridge: irc on ~chat, irc on libera and xmpp muc.

+GRU Devlog 15 - ocpu, yemu and licenses +

+ +
November 07, 2021 — +G1n +
+ + +

This week wasn’t very productive. I was working on one of my personal projects.

+ +

I have added ADD for registers, INC, DEC and NOP instructions.

+ +

Also codeberg informed me that yemu has to have license, and I fast added MIT license to all our projects.

+ +

+GRU Devlog 14 - ocpu and yemu +

+ +
October 31, 2021 — +G1n +
+ + +

This week I was working on ocpu emulator. So using it we can know if specifications can be implemented. +It helps me adding some description to it.

+ +

First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator +based on template (that should be placed in docs one day). Now if someone would like to add some architecture to +our emulator they won’t need to rewrite it from scratch.

+ +

I also added –system flag to yemu so architecture can be choosen more user-friendly way.

+ +

Currently in ocpu emulator only mov and add instructions are implemented. +We also added some description to commands in specifications, so it is easier to understand what it should do

+ +

+GRU Devlog 13 - ocpu thoughts and some elecronics +

+ +
October 24, 2021 — +G1n +
+ + +

This week was very busy week at school and I had no time for programming.

+ +

But in the start of week I was thinking about making ocpu specs more Turing-complete. +I still think it is not done but maybe it will in some time (and of course more description required).

+ +

But I had time to buy some transistors and other electronics. Currently I am trying to make half-adder.

+ +

I have created tiny log page - lolcpu. I am going to post there some of my +electronic ideas, circuits and progress in doing some electronic things.

+ +

+GRU Devlog 12 - yemu, gasm and ocpu +

+ +
October 17, 2021 — +G1n +
+ + +

This week I have done several new instructions for yemu. For example all transfer instructions.

+ +

Also I have rewritten gasm to support 6502, published it and it should help me with debugging yemu. +It supports not very a lot instructions but I hope it is good start.

+ +

But I think the coolest what I did this week is ocpu proccessor specification. +Currently it is draft but i have already published it here. +I hope this specifications will be Turing complete and we will try to implement it in real world. +But firstly we need to make this specififcations complete, assembler and emulator for it.

+ +

Also smlckz’s idea was to make translator from ocpu assembler instructions to avr to emulate it on arduino!

+GRU Devlog 11 - yemu and channel on libera.chat +

+ +
October 08, 2021 — +G1n +
+ + +

I am making this devlog a bit earlier, because I will be busy on weekends.

+ +

This week I didn’t have plan, but it seems I have done some things to yemu: added loading programs +from binary file and several instructions - TAX, TAY and NOP.

+ +

I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in +testing yemu.

+ +

I was trying to make some daily notes in Org Roam (and moved devlog notes there), but it wasn’t +very success, but I hope to do it more often :)

+ +

Also I have registered #gru channel on libera, so you can join us also on libera.chat :)

+GRU Devlog 10 - orsh now like proper shell and gasm +

+ +
October 03, 2021 — +G1n +
+ + +

Hooray! Today is 10’s GRU Devlog! :)

+ +

This week i was trying to make notes to org document, to not forget something and put TODOs +there for future weeks.

+ +

First several days was the most valuable - readline support and signal handling! +This means you can use emacs-like bindings there (but i think readline also supports vi bindings, +so maybe i will add them too!)

+ +

Also we now have very minimal completion support there :), but still proper function need to be added +for that (currently only filenames completion)

+ +

Orsh also has one session history, so you don’t need to rewrite command from scratch now

+ +

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining. +We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.

+ +

Hope you liked this post and you will join our XMPP muc (if you are not already there) :). +If you would like to help me, contact me via email, xmpp or irc :)

+GRU Devlog 5 - First contribution from other person, coreutils and gxt (tui text editor) +

+ +
August 29, 2021 — +G1n +
+ + +

This week I had a lot of new ideas. But I think we have to work on something that +have already been started. +Also we now have one more coreutils rewrite +(now on C to more easily port it to Orion in future).

+ +

Also i have started working on some +projects that is not ready to be published yet. One of them is gxt - tui text editor.

+ +

Currently it can only move cursor and display files. But I think I’ll publish it next week +when editing will be working.

+ +

Bad news is that my school lessons will start next week so maybe this devlogs won’t be +published every week, because of not enough work done. But I don’t know, maybe I’ll have +enough time.

+ +

Also good news - we have first contribution on codeberg to grsh. I didn’t know this person +(because he is not from tildeverse :) ), so it is cool!

+ +

Hope you liked this devlog! If you can somehow help us, please contribute to our projects +on tildegit/codeberg and/or message me in someway :)

+GRU DevLog 3 - Orion and dreams about GRU software future +

+ +
August 15, 2021 — +G1n +
+ + +

This week I was trying to make interrupts, paging and other memory things working in Orion. +I found this guide and tried to follow it without rewriting the whole project: +http://www.jamesmolloy.co.uk/index.html

+ +

For now only Global Descriptor Table maybe working.

+ +

My current goals/dreams:

+ +
    +

  • make filesystem (the coolest would be make Ext2 driver)

    • +

  • build GCC hosted compiler (this will help GCC understand our OS better)

    • +
+ + +

My very future dreams:

+ +
    +

  • make kernel, libs, ports and soft in different repos

    • +

  • make proper way to make “distros” on our kernel

    • +

  • make some website with mirror of ports scripts (like in Serenity OS but not in one repo with +everything and tool for searching and downloading ports from that mirror)

    • +

  • maybe (if i will work a lot on this projects) I’ll make one more account on tilde.team +for our organisation (domain name - gru.ttm.sh, is cool), but i’ll ask admins about that

    • +
+ + +

Also I think Orion need new name because i found several projects with this name :)

+ +

Some ideas about the GRU name:

+ +
    +

  • GRU rocks (or rocking) UNIX

    • +

  • GloRious UNIX

    • +

  • GloRious Union

    • +
+ + +

If you can help me or have some ideas (name/names or anything else) contact me via email +or any other type of contact (irc: g1n on tilde.chat, xmpp: g1n@hmm.st)

+GRU Devlog 17-18 - coreutils, EGG and ideas +

+ +
November 28, 2021 — +G1n +
+ + +

Last week I didn’t make devlog because was busy and haven’t done anything useful except +mkdir for coreutils.

+ +

This week I started from try to make something in framebuffer but currently nothing, because +I can’t even understand why my code can’t see size of my display. I think E will require making +something like Elib for easier communicating with E (but it will be in very far future…)

+ +

Then I made echo and very simple ls for coreutils. I am going to add more flags to ls next week. +This week I also have made simple irc bot in python, so I will try to make simple clone of suckless ii +on C (i think name gic is now really good so if you have ideas please suggest them to me). +Currently I don’t reallly understand how to work with sockets but I will try to do something.

+GRU Devlog 16 - ormp and EGG +

+ +
November 14, 2021 — +G1n +
+ + +

This week i was working on one more new project - ormp. It will be terminal multiplexor. +Currently i am doing it in ncurses. For current time it is not working - can just handle input but not display it.

+ +

Also i have an idea for new projects - EGG (Extended/Exciting GRU GUI). I am planning some proj in this category - eggwm, eggterm, eggmenu and E. +E would be a new display server. We will need to have it for Orion in future. Currently i am planning to do it or on fbdev or on DRM/KMS.

+ +

Also now yemu can be compiled with different compilers, -pedantic flag was added to makefile and all errors fixed.

+ +

And now our channels are bridged via matterbridge: irc on ~chat, irc on libera and xmpp muc.

+GRU Devlog 10 - orsh now like proper shell and gasm +

+ +
October 03, 2021 — +G1n +
+ + +

Hooray! Today is 10’s GRU Devlog! :)

+ +

This week i was trying to make notes to org document, to not forget something and put TODOs +there for future weeks.

+ +

First several days was the most valuable - readline support and signal handling! +This means you can use emacs-like bindings there (but i think readline also supports vi bindings, +so maybe i will add them too!)

+ +

Also we now have very minimal completion support there :), but still proper function need to be added +for that (currently only filenames completion)

+ +

Orsh also has one session history, so you don’t need to rewrite command from scratch now

+ +

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining. +We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.

+ +

Hope you liked this post and you will join our XMPP muc (if you are not already there) :). +If you would like to help me, contact me via email, xmpp or irc :)

+GRU Devlog 4 - more projects started, webpage for GRU and organizations on tildegit/codeberg +

+ +
August 22, 2021 — +G1n +
+ + +

In first days of this week I thought it will be not very productive. +But I was wrong.

+ +

We now have webpage and organizations on tildegit/codeberg:

+ +

https://g1n.ttm.sh/gru/

+ +

Also I am working on some new projects:

+ +
    +

  • orcc - GRU/Orion Compilers Collection (but currently I am working only on lexer so it is not published yet)

    • +

  • gasm - GRU assembler (maybe will be part of GRU binutils. Also not published yet)

    • +

  • hexutils - I think hexdump, xxd and some other utils will be in this project

    • +
+ + +

Also I tryed to advertize GRU on ~chat, some users liked us, +so maybe soon someone will help me with all this.

+ +

And of course if you can help me please contact me in someway! :)

+GRU Devlog 19 - gic and several libs +

+ +
December 05, 2021 — +G1n +
+ + +

This week started with making gic (maybe name will be change). As I have written before +it is going to be suckless ii clone. Also I started making girclib - simple C library for irc +protocol. I think it will be published as separate project, because I would like to make it +for both: client and server. I don’t yet how it will be done but we will see…

+ +

Then I thought that would be cool to have own libc, but have no knowledge how it speaks with OS. +Then I understood that on linux it is working via syscalls. So started making liblinux - +C library for linux syscalls. Using it we won’t need to use assembly a lot in our libc. Currently +write and read syscalls are done and programmer can use it if passed -I, -L and -l flags to compiler. +And it is already published! (check codeberg or tildegit)

+ +

After understanding how to create proper makefile with liblinux, I started making olibc. Currently +it has very tiny number of features. But string.h is mostly done! I don’t know when I will fill that +it will be ready enough to be published, but hope to have useful functions and test suit there till +that time.

+ +

When olibc will be done enough I am going to start making C compiler (already have some code, but it +is old and I not understand how it works, so need to be rewritten). Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

+GRU DevLog 1 - gros sources published and add wc to grutils +

+ +
August 01, 2021 — +G1n +
+ + +

I didn’t make a lot work this week, so i think this devlogs should be renamed from “week number” to just “number” +Ok, so what i did this week: +- Add wc to grutils +- Published gros +- Add basic shell and some commands for gros

+ +

I know that is not a lot, but i was reading some osdev articles and books. +Currently I would like to implement basic filesystem but i don’t know what to do.

+ +

Some goals for gros (I will add that to gros readme): +- Filesystem (FAT or Ext2) +- ELF or other executable formats +- LibC (for compiling C programs) +- Maybe basic networking but after all of that

+ +

All code in osdev wiki is for C so I need to implement it myself (or port existing rust code)

+ +

If you can help me somehow please contact me via email (g1n@ttm.sh) or in other ways (~chat irc, xmpp)

+GRU DevLog Week 0 - grsh, grutils and start of gros +

+ +
July 25, 2021 — +G1n +
+ + +

So I have started new project this week - grsh! It is shell written on Rust. Also, for now, other rewrites of coreutils are there.

+ +

What grsh can do for this moment: echo some variables (pwd, user, home, status of previous command using $?) and text; true, false, : - set status; pwd shows current dir, also comments and cd working, basic piping (thanks to that article and of course executing not builtin command also working.

+ +

Some grutils that I made: ls, touch, mkdir/rmdir, rm, grep, head/tail, yes, cat.

+ +

TODOs exist in grsh repo - so you can read there some of my plans.

+ +

Yesterday i have started GROS - OS on Rust! But I haven’t published code yet because it not have that minimum of funcionality that i want. Thanks for that site for teaching how to make basics - https://os.phil-opp.com

+ +

So it was first of GRU Devlog! Thanks for reading! If you want to contribute to some of that project write me an email - g1n@ttm.sh , or contact me in other ways

+GRU Devlog 5 - First contribution from other person, coreutils and gxt (tui text editor) +

+ +
August 29, 2021 — +G1n +
+ + +

This week I had a lot of new ideas. But I think we have to work on something that +have already been started. +Also we now have one more coreutils rewrite +(now on C to more easily port it to Orion in future).

+ +

Also i have started working on some +projects that is not ready to be published yet. One of them is gxt - tui text editor.

+ +

Currently it can only move cursor and display files. But I think I’ll publish it next week +when editing will be working.

+ +

Bad news is that my school lessons will start next week so maybe this devlogs won’t be +published every week, because of not enough work done. But I don’t know, maybe I’ll have +enough time.

+ +

Also good news - we have first contribution on codeberg to grsh. I didn’t know this person +(because he is not from tildeverse :) ), so it is cool!

+ +

Hope you liked this devlog! If you can somehow help us, please contribute to our projects +on tildegit/codeberg and/or message me in someway :)

+GRU Devlog 20 - olibc +

+ +
December 12, 2021 — +G1n +
+ + +

This week I was making olibc. I was implementing <string.h>. Also I was fixing liblinux to +be able to include it without need to use full path in #include. I had several other issues +with it and also fixed them.

+ +

My current goal is to implement <string.h> and after that I am planning to publish it. +Currently most of funcs are implemented. Making strtok now but all other functions need +locale.h and I don’t know yet how I will be implemented. But it is already cool that we +have most of functions that should be in <string.h>!

+ +

Also we now have gru webpage on codeberg! Maybe next week I +will move all devlogs to gru webpage so it will be easier to move.

+GRU Devlog 14 - ocpu and yemu +

+ +
October 31, 2021 — +G1n +
+ + +

This week I was working on ocpu emulator. So using it we can know if specifications can be implemented. +It helps me adding some description to it.

+ +

First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator +based on template (that should be placed in docs one day). Now if someone would like to add some architecture to +our emulator they won’t need to rewrite it from scratch.

+ +

I also added –system flag to yemu so architecture can be choosen more user-friendly way.

+ +

Currently in ocpu emulator only mov and add instructions are implemented. +We also added some description to commands in specifications, so it is easier to understand what it should do

+ +

October 08, 2021 — +G1n +

I am making this devlog a bit earlier, because I will be busy on weekends.

+ +

This week I didn’t have plan, but it seems I have done some things to yemu: added loading programs +from binary file and several instructions - TAX, TAY and NOP.

+ +

I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in +testing yemu.

I was trying to make some daily notes in Org Roam (and moved devlog notes there), but it wasn’t +very success, but I hope to do it more often :)

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining. +We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.

+ +

+GRU Devlog 9 - orsh, orion, bootloader, GRU xmpp room and logo +

+ +
September 26, 2021 — +G1n +
+ + +

This week I didn’t commited a lot, but started some new projects. +I made orsh signal handling working (so it won’t exit on ^C) and homedir “handling” +(can replace homedir in prompt with ~, and you can use ‘cd ~’ or just ‘cd’ to change +dir to homedir)

+ +

Also I started making bootloader, but for now it can only detect what CPU is (intel if x86 and amd if x86_64), +some additional instructions (msr) and if apic is avalible.

+ +

I was trying to make something with orion fs, maybe it will use pak files for initrd. Currently i am making archiver +for it, but after that i will need to understand more how vfs working and rewrite initrd to use pak files.

+ +

We now have xmpp room (gru@conference.hmm.st) and logo! Thanks to chunk for it!

+ +

I was thinking about making weekly or monthly “conferences”. We could do it via jitsi tildeverse instance or tilde.tel +(tel.tilde.org.nz) conference. I think jitsi is better, but we should try tilde.tel confernce at least once, why not? :)

+GRU Devlog 8 - orsh and published initrd +

September 19, 2021 — +G1n +

This week I have published initrd, but it is not working as expected.

+ +

Also I have started one more project - orsh. It is one more shell, but now in C. +Maybe it will be easier to port to Orion. It already supports ; but they are working a bit weird.

+ +

Also in orsh you can work with environment variables. +From today’s morning I am trying to replace bash with it, but still a lot need to be done.

+GRU Devlog 7 - keyboard, paging and WIP initrd in Orion +

+ +
September 12, 2021 — +G1n +
+ + +

This week I was improving Orion. First I made keyboard working, next day paging! +Also I have added several new LibC functions. +Today I have made scrolling working.

+ +

Last few days I was trying to make initrd working +(this required heap implementing so I also did that but I don’t know if it works correctly). +Currently it can only output /dev directory.

+ +

But I made something wrong with %x in printf and it can display weird chars first +and then contents of files!

+ +

I have started working on yemu - Yet another EMUlator. It currently supports only 6502 +proccessor with tiny number of instructions (LDA, LDX and LDY)

+GRU Devlog 5 - First contribution from other person, coreutils and gxt (tui text editor) +

+ +
August 29, 2021 — +G1n +
+ + +

This week I had a lot of new ideas. But I think we have to work on something that +have already been started. +Also we now have one more coreutils rewrite +(now on C to more easily port it to Orion in future).

+ +

Also i have started working on some +projects that is not ready to be published yet. One of them is gxt - tui text editor.

+ +

Currently it can only move cursor and display files. But I think I’ll publish it next week +when editing will be working.

+ +

Bad news is that my school lessons will start next week so maybe this devlogs won’t be +published every week, because of not enough work done. But I don’t know, maybe I’ll have +enough time.

+ +

Also good news - we have first contribution on codeberg to grsh. I didn’t know this person +(because he is not from tildeverse :) ), so it is cool!

Also I am working on some new projects:

    +

  • orcc - GRU/Orion Compilers Collection (but currently I am working only on lexer so it is not published yet)

    • +

  • gasm - GRU assembler (maybe will be part of GRU binutils. Also not published yet)

    • +

  • hexutils - I think hexdump, xxd and some other utils will be in this project

+GRU DevLog 3 - Orion and dreams about GRU software future +

+ +
August 15, 2021 — +G1n +
+ + +

This week I was trying to make interrupts, paging and other memory things working in Orion. +I found this guide and tried to follow it without rewriting the whole project: +http://www.jamesmolloy.co.uk/index.html

+ +

For now only Global Descriptor Table maybe working.

+ +

My current goals/dreams:

+ +
    +

  • make filesystem (the coolest would be make Ext2 driver)

    • +

  • build GCC hosted compiler (this will help GCC understand our OS better)

    • +
+ + +

My very future dreams:

+ +
    +

  • make kernel, libs, ports and soft in different repos

    • +

  • make proper way to make “distros” on our kernel

    • +

  • make some website with mirror of ports scripts (like in Serenity OS but not in one repo with +everything and tool for searching and downloading ports from that mirror)

    • +

  • maybe (if i will work a lot on this projects) I’ll make one more account on tilde.team +for our organisation (domain name - gru.ttm.sh, is cool), but i’ll ask admins about that

    • +
+ + +

Also I think Orion need new name because i found several projects with this name :)

+ +

Some ideas about the GRU name:

+ +
    +

  • GRU rocks (or rocking) UNIX

    • +

  • GloRious UNIX

    • +

  • GloRious Union

    • +
+ + +

August 08, 2021 — +G1n +

This week I was developing new OS - Orion.

+ +

I don’t understand very basic osdev thing so I decided to make OS on C and Asm. +Currently that can just output text (with printf arguments) on screen and serial. +Now gros is much cooler than Orion - it has input, interupts and a lot of else. +But maybe I’ll understand OSdev better. +Currently working on GDT (global descriptor table) and than will work on +interrupts and exceptions.

August 01, 2021 — +G1n +

I didn’t make a lot work this week, so i think this devlogs should be renamed from “week number” to just “number” +Ok, so what i did this week: +- Add wc to grutils +- Published gros +- Add basic shell and some commands for gros

+ +

I know that is not a lot, but i was reading some osdev articles and books. +Currently I would like to implement basic filesystem but i don’t know what to do.

+ +

Some goals for gros (I will add that to gros readme): +- Filesystem (FAT or Ext2) +- ELF or other executable formats +- LibC (for compiling C programs) +- Maybe basic networking but after all of that

+ +

All code in osdev wiki is for C so I need to implement it myself (or port existing rust code)

+GRU DevLog Week 0 - grsh, grutils and start of gros +

+ +
July 25, 2021 — +G1n +
+ + +

So I have started new project this week - grsh! It is shell written on Rust. Also, for now, other rewrites of coreutils are there.

+ +

What grsh can do for this moment: echo some variables (pwd, user, home, status of previous command using $?) and text; true, false, : - set status; pwd shows current dir, also comments and cd working, basic piping (thanks to that article and of course executing not builtin command also working.

+ +

Some grutils that I made: ls, touch, mkdir/rmdir, rm, grep, head/tail, yes, cat.

+ +

TODOs exist in grsh repo - so you can read there some of my plans.

+ +

Yesterday i have started GROS - OS on Rust! But I haven’t published code yet because it not have that minimum of funcionality that i want. Thanks for that site for teaching how to make basics - https://os.phil-opp.com

+ +

So it was first of GRU Devlog! Thanks for reading! If you want to contribute to some of that project write me an email - g1n@ttm.sh , or contact me in other ways

Also i have an idea for new projects - EGG (Extended/Exciting GRU GUI). I am planning some proj in this category - eggwm, eggterm, eggmenu and E. +E would be a new display server. We will need to have it for Orion in future. Currently i am planning to do it or on fbdev or on DRM/KMS.

+ +

Also now yemu can be compiled with different compilers, -pedantic flag was added to makefile and all errors fixed.

+ +

I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in +testing yemu.

This week I was making olibc. I was implementing <string.h>. Also I was fixing liblinux to +be able to include it without need to use full path in #include. I had several other issues +with it and also fixed them.

My current goal is to implement <string.h> and after that I am planning to publish it. +Currently most of funcs are implemented. Making strtok now but all other functions need +locale.h and I don’t know yet how I will be implemented. But it is already cool that we +have most of functions that should be in <string.h>!

+GRU Devlog 19 - gic and several libs +

+ +
December 05, 2021 — +G1n +

This week started with making gic (maybe name will be change). As I have written before +it is going to be suckless ii clone. Also I started making girclib - simple C library for irc +protocol. I think it will be published as separate project, because I would like to make it +for both: client and server. I don’t yet how it will be done but we will see…

+ +

Then I thought that would be cool to have own libc, but have no knowledge how it speaks with OS. +Then I understood that on linux it is working via syscalls. So started making liblinux - +C library for linux syscalls. Using it we won’t need to use assembly a lot in our libc. Currently +write and read syscalls are done and programmer can use it if passed -I, -L and -l flags to compiler. +And it is already published! (check codeberg or tildegit)

+ +

After understanding how to create proper makefile with liblinux, I started making olibc. Currently +it has very tiny number of features. But string.h is mostly done! I don’t know when I will fill that +it will be ready enough to be published, but hope to have useful functions and test suit there till +that time.

+ +

When olibc will be done enough I am going to start making C compiler (already have some code, but it +is old and I not understand how it works, so need to be rewritten). Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

This week wasn’t very productive. I was working on one of my personal projects.

I have added ADD for registers, INC, DEC and NOP instructions.

Also codeberg informed me that yemu has to have license, and I fast added MIT license to all our projects.

October 03, 2021 — +G1n +
+ + +

Hooray! Today is 10’s GRU Devlog! :)

+ +

This week i was trying to make notes to org document, to not forget something and put TODOs +there for future weeks.

+ +

First several days was the most valuable - readline support and signal handling! +This means you can use emacs-like bindings there (but i think readline also supports vi bindings, +so maybe i will add them too!)

+ +

Also we now have very minimal completion support there :), but still proper function need to be added +for that (currently only filenames completion)

+ +

Orsh also has one session history, so you don’t need to rewrite command from scratch now

+ +

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining. +We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.

+ +
October 24, 2021 — +G1n +
+ + +

This week was very busy week at school and I had no time for programming.

+ +

But in the start of week I was thinking about making ocpu specs more Turing-complete. +I still think it is not done but maybe it will in some time (and of course more description required).

+ +

But I had time to buy some transistors and other electronics. Currently I am trying to make half-adder.

I have created tiny log page - lolcpu. I am going to post there some of my +electronic ideas, circuits and progress in doing some electronic things.

+GRU Devlog 14 - ocpu and yemu +

+ +
October 31, 2021 — +G1n +
+ + +

This week I was working on ocpu emulator. So using it we can know if specifications can be implemented. +It helps me adding some description to it.

+ +

First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator +based on template (that should be placed in docs one day). Now if someone would like to add some architecture to +our emulator they won’t need to rewrite it from scratch.

+ +

I also added –system flag to yemu so architecture can be choosen more user-friendly way.

+ +

Currently in ocpu emulator only mov and add instructions are implemented. +We also added some description to commands in specifications, so it is easier to understand what it should do

+GRU Devlog 12 - yemu, gasm and ocpu +

+ +
October 17, 2021 — +G1n +
+ + +

This week I have done several new instructions for yemu. For example all transfer instructions.

+ +

Also I have rewritten gasm to support 6502, published it and it should help me with debugging yemu. +It supports not very a lot instructions but I hope it is good start.

+ +

But I think the coolest what I did this week is ocpu proccessor specification. +Currently it is draft but i have already published it here. +I hope this specifications will be Turing complete and we will try to implement it in real world. +But firstly we need to make this specififcations complete, assembler and emulator for it.

+ +

Also smlckz’s idea was to make translator from ocpu assembler instructions to avr to emulate it on arduino!

+GRU Devlog 20 - olibc +

+ +
December 12, 2021 — +G1n +
+ + +

This week I was making olibc. I was implementing <string.h>. Also I was fixing liblinux to +be able to include it without need to use full path in #include. I had several other issues +with it and also fixed them.

+ +

My current goal is to implement <string.h> and after that I am planning to publish it. +Currently most of funcs are implemented. Making strtok now but all other functions need +locale.h and I don’t know yet how I will be implemented. But it is already cool that we +have most of functions that should be in <string.h>!

+ +

Also we now have gru webpage on codeberg! Maybe next week I +will move all devlogs to gru webpage so it will be easier to move.

+GRU Devlog 19 - gic and several libs +

+ +
December 05, 2021 — +G1n +
+ + +

This week started with making gic (maybe name will be change). As I have written before +it is going to be suckless ii clone. Also I started making girclib - simple C library for irc +protocol. I think it will be published as separate project, because I would like to make it +for both: client and server. I don’t yet how it will be done but we will see…

+ +

Then I thought that would be cool to have own libc, but have no knowledge how it speaks with OS. +Then I understood that on linux it is working via syscalls. So started making liblinux - +C library for linux syscalls. Using it we won’t need to use assembly a lot in our libc. Currently +write and read syscalls are done and programmer can use it if passed -I, -L and -l flags to compiler. +And it is already published! (check codeberg or tildegit)

+ +

After understanding how to create proper makefile with liblinux, I started making olibc. Currently +it has very tiny number of features. But string.h is mostly done! I don’t know when I will fill that +it will be ready enough to be published, but hope to have useful functions and test suit there till +that time.

+ +

When olibc will be done enough I am going to start making C compiler (already have some code, but it +is old and I not understand how it works, so need to be rewritten). Also I hope that we will have +enough toolchain (or I will have enough knowledge to implement things that are not done faster) +for our own Linux or BSD distribution. But that will be in future…

+GRU Devlog 4 - more projects started, webpage for GRU and organizations on tildegit/codeberg +

+ +
August 22, 2021 — +G1n +
+ + +

In first days of this week I thought it will be not very productive. +But I was wrong.

+ +

We now have webpage and organizations on tildegit/codeberg:

+ +

https://g1n.ttm.sh/gru/

+ +

Also I am working on some new projects:

+ +
    +

  • orcc - GRU/Orion Compilers Collection (but currently I am working only on lexer so it is not published yet)

    • +

  • gasm - GRU assembler (maybe will be part of GRU binutils. Also not published yet)

    • +

  • hexutils - I think hexdump, xxd and some other utils will be in this project

    • +
+ + +

Also I tryed to advertize GRU on ~chat, some users liked us, +so maybe soon someone will help me with all this.

+ +

And of course if you can help me please contact me in someway! :)

+ +
October 08, 2021 — +G1n +
+ + +

I am making this devlog a bit earlier, because I will be busy on weekends.

+ +

This week I didn’t have plan, but it seems I have done some things to yemu: added loading programs +from binary file and several instructions - TAX, TAY and NOP.

+ +

I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in +testing yemu.

+ +

I was trying to make some daily notes in Org Roam (and moved devlog notes there), but it wasn’t +very success, but I hope to do it more often :)

+GRU Devlog 9 - orsh, orion, bootloader, GRU xmpp room and logo +

+ +
September 26, 2021 — +G1n +
+ + +

This week I didn’t commited a lot, but started some new projects. +I made orsh signal handling working (so it won’t exit on ^C) and homedir “handling” +(can replace homedir in prompt with ~, and you can use ‘cd ~’ or just ‘cd’ to change +dir to homedir)

+ +

Also I started making bootloader, but for now it can only detect what CPU is (intel if x86 and amd if x86_64), +some additional instructions (msr) and if apic is avalible.

+ +

I was trying to make something with orion fs, maybe it will use pak files for initrd. Currently i am making archiver +for it, but after that i will need to understand more how vfs working and rewrite initrd to use pak files.

+ +

We now have xmpp room (gru@conference.hmm.st) and logo! Thanks to chunk for it!

+ +

I was thinking about making weekly or monthly “conferences”. We could do it via jitsi tildeverse instance or tilde.tel +(tel.tilde.org.nz) conference. I think jitsi is better, but we should try tilde.tel confernce at least once, why not? :)

Also I have started one more project - orsh. It is one more shell, but now in C. +Maybe it will be easier to port to Orion. It already supports ; but they are working a bit weird.

+ +

Also in orsh you can work with environment variables. +From today’s morning I am trying to replace bash with it, but still a lot need to be done.

September 12, 2021 — +G1n +

This week I was improving Orion. First I made keyboard working, next day paging! +Also I have added several new LibC functions. +Today I have made scrolling working.

+ +

Last few days I was trying to make initrd working +(this required heap implementing so I also did that but I don’t know if it works correctly). +Currently it can only output /dev directory.

+ +

But I made something wrong with %x in printf and it can display weird chars first +and then contents of files!

+ +

I have started working on yemu - Yet another EMUlator. It currently supports only 6502 +proccessor with tiny number of instructions (LDA, LDX and LDY)

+ +

Today we have fixed interrupts in Orion and now I can implement timer, paging, keyboard +and a lot of other things (thanks to quinn and smlckz from tilde.chat)

+GRU DevLog 3 - Orion and dreams about GRU software future +

+ +
August 15, 2021 — +G1n +
+ + +

This week I was trying to make interrupts, paging and other memory things working in Orion. +I found this guide and tried to follow it without rewriting the whole project: +http://www.jamesmolloy.co.uk/index.html

+ +

For now only Global Descriptor Table maybe working.

+ +

My current goals/dreams:

+ +
    +

  • make filesystem (the coolest would be make Ext2 driver)

    • +

  • build GCC hosted compiler (this will help GCC understand our OS better)

    • +
+ + +

My very future dreams:

+ +
    +

  • make kernel, libs, ports and soft in different repos

    • +

  • make proper way to make “distros” on our kernel

    • +

  • make some website with mirror of ports scripts (like in Serenity OS but not in one repo with +everything and tool for searching and downloading ports from that mirror)

    • +

  • maybe (if i will work a lot on this projects) I’ll make one more account on tilde.team +for our organisation (domain name - gru.ttm.sh, is cool), but i’ll ask admins about that

    • +
+ + +

Also I think Orion need new name because i found several projects with this name :)

+ +

Some ideas about the GRU name:

+ +
    +

  • GRU rocks (or rocking) UNIX

    • +

  • GloRious UNIX

    • +

  • GloRious Union

    • +
+ + +

If you can help me or have some ideas (name/names or anything else) contact me via email +or any other type of contact (irc: g1n on tilde.chat, xmpp: g1n@hmm.st)

+GRU DevLog 2 - Orion +

+ +
August 08, 2021 — +G1n +
+ + +

This week I was developing new OS - Orion.

+ +

I don’t understand very basic osdev thing so I decided to make OS on C and Asm. +Currently that can just output text (with printf arguments) on screen and serial. +Now gros is much cooler than Orion - it has input, interupts and a lot of else. +But maybe I’ll understand OSdev better. +Currently working on GDT (global descriptor table) and than will work on +interrupts and exceptions.

+ +

Of course if you can help me contact me throught email or in other ways!

+GRU Devlog 16 - ormp and EGG +

+ +
November 14, 2021 — +G1n +
+ + +

This week i was working on one more new project - ormp. It will be terminal multiplexor. +Currently i am doing it in ncurses. For current time it is not working - can just handle input but not display it.

+ +

Also i have an idea for new projects - EGG (Extended/Exciting GRU GUI). I am planning some proj in this category - eggwm, eggterm, eggmenu and E. +E would be a new display server. We will need to have it for Orion in future. Currently i am planning to do it or on fbdev or on DRM/KMS.

+ +

Also now yemu can be compiled with different compilers, -pedantic flag was added to makefile and all errors fixed.

And now our channels are bridged via matterbridge: irc on ~chat, irc on libera and xmpp muc.

+GRU Devlog 10 - orsh now like proper shell and gasm +

+ +
October 03, 2021 — +G1n +
+ + +

Hooray! Today is 10’s GRU Devlog! :)

+ +

This week i was trying to make notes to org document, to not forget something and put TODOs +there for future weeks.

+ +

First several days was the most valuable - readline support and signal handling! +This means you can use emacs-like bindings there (but i think readline also supports vi bindings, +so maybe i will add them too!)

+ +

Also we now have very minimal completion support there :), but still proper function need to be added +for that (currently only filenames completion)

+ +

Orsh also has one session history, so you don’t need to rewrite command from scratch now

+ +

And I have started to use it as my main (but had some problems after chsh, so currently is autostarts after bash +and i can exit from there any time i will need)

+ +

Then I have started making our own assembler - gasm. Currently it only supports NOP, so i haven’t published it yet.

+ +

This week I also registered to ~news and shared devlog there (i think this devlog also will be there ;) ) +If you have lobste.rs account please contact me to invite me, if you can, because it may advertize GRU more!

+ +

Today (Sunday) we had first testing GRU meeting via Jitsi. Thanks to r1k for joining. +We need to make something like plan our schedule (to know about what to speak) and discuss meeting time better.

+ +

Hope you liked this post and you will join our XMPP muc (if you are not already there) :). +If you would like to help me, contact me via email, xmpp or irc :)

+GRU Devlog 9 - orsh, orion, bootloader, GRU xmpp room and logo +

+ +
September 26, 2021 — +G1n +
+ + +

This week I didn’t commited a lot, but started some new projects. +I made orsh signal handling working (so it won’t exit on ^C) and homedir “handling” +(can replace homedir in prompt with ~, and you can use ‘cd ~’ or just ‘cd’ to change +dir to homedir)

+ +

Also I started making bootloader, but for now it can only detect what CPU is (intel if x86 and amd if x86_64), +some additional instructions (msr) and if apic is avalible.

+ +

I was trying to make something with orion fs, maybe it will use pak files for initrd. Currently i am making archiver +for it, but after that i will need to understand more how vfs working and rewrite initrd to use pak files.

+ +

We now have xmpp room (gru@conference.hmm.st) and logo! Thanks to chunk for it!

+ +

I was thinking about making weekly or monthly “conferences”. We could do it via jitsi tildeverse instance or tilde.tel +(tel.tilde.org.nz) conference. I think jitsi is better, but we should try tilde.tel confernce at least once, why not? :)

+GRU Devlog 8 - orsh and published initrd +

+ +
September 19, 2021 — +G1n +
+ + +

This week I have published initrd, but it is not working as expected.

+ +

Also I have started one more project - orsh. It is one more shell, but now in C. +Maybe it will be easier to port to Orion. It already supports ; but they are working a bit weird.

+ +

Also in orsh you can work with environment variables. +From today’s morning I am trying to replace bash with it, but still a lot need to be done.

+GRU Devlog 13 - ocpu thoughts and some elecronics +

+ +
October 24, 2021 — +G1n +
+ + +

This week was very busy week at school and I had no time for programming.

+ +

But in the start of week I was thinking about making ocpu specs more Turing-complete. +I still think it is not done but maybe it will in some time (and of course more description required).

+ +

But I had time to buy some transistors and other electronics. Currently I am trying to make half-adder.

+ +

I have created tiny log page - lolcpu. I am going to post there some of my +electronic ideas, circuits and progress in doing some electronic things.

+ +

+GRU Devlog 4 - more projects started, webpage for GRU and organizations on tildegit/codeberg +

+ +
August 22, 2021 — +G1n +
+ + +

In first days of this week I thought it will be not very productive. +But I was wrong.

+ +

We now have webpage and organizations on tildegit/codeberg:

+ +

https://g1n.ttm.sh/gru/

+ +

Also I am working on some new projects:

+ +
    +

  • orcc - GRU/Orion Compilers Collection (but currently I am working only on lexer so it is not published yet)

    • +

  • gasm - GRU assembler (maybe will be part of GRU binutils. Also not published yet)

    • +

  • hexutils - I think hexdump, xxd and some other utils will be in this project

    • +
+ + +

Also I tryed to advertize GRU on ~chat, some users liked us, +so maybe soon someone will help me with all this.

+ +

And of course if you can help me please contact me in someway! :)

+GRU Devlog 16 - ormp and EGG +

November 14, 2021 — +G1n +

This week i was working on one more new project - ormp. It will be terminal multiplexor. +Currently i am doing it in ncurses. For current time it is not working - can just handle input but not display it.

+ +

Also i have an idea for new projects - EGG (Extended/Exciting GRU GUI). I am planning some proj in this category - eggwm, eggterm, eggmenu and E. +E would be a new display server. We will need to have it for Orion in future. Currently i am planning to do it or on fbdev or on DRM/KMS.

+GRU Devlog 15 - ocpu, yemu and licenses +

+ +
November 07, 2021 — +G1n +
+ + +

This week wasn’t very productive. I was working on one of my personal projects.

+ +

I have added ADD for registers, INC, DEC and NOP instructions.

+ +

Also codeberg informed me that yemu has to have license, and I fast added MIT license to all our projects.

+GRU Devlog 14 - ocpu and yemu +

+ +
October 31, 2021 — +G1n +
+ + +

This week I was working on ocpu emulator. So using it we can know if specifications can be implemented. +It helps me adding some description to it.

+ +

First I made yemu a bit modular, so you need to add several lines to main file and then building your emulator +based on template (that should be placed in docs one day). Now if someone would like to add some architecture to +our emulator they won’t need to rewrite it from scratch.

+ +

I also added –system flag to yemu so architecture can be choosen more user-friendly way.

+ +

Currently in ocpu emulator only mov and add instructions are implemented. +We also added some description to commands in specifications, so it is easier to understand what it should do

+ +

+GRU Devlog 12 - yemu, gasm and ocpu +

+ +
October 17, 2021 — +G1n +
+ + +

This week I have done several new instructions for yemu. For example all transfer instructions.

+ +

Also I have rewritten gasm to support 6502, published it and it should help me with debugging yemu. +It supports not very a lot instructions but I hope it is good start.

+ +

But I think the coolest what I did this week is ocpu proccessor specification. +Currently it is draft but i have already published it here. +I hope this specifications will be Turing complete and we will try to implement it in real world. +But firstly we need to make this specififcations complete, assembler and emulator for it.

+ +

Also smlckz’s idea was to make translator from ocpu assembler instructions to avr to emulate it on arduino!

+GRU Devlog 11 - yemu and channel on libera.chat +

+ +
October 08, 2021 — +G1n +
+ + +

I am making this devlog a bit earlier, because I will be busy on weekends.

+ +

This week I didn’t have plan, but it seems I have done some things to yemu: added loading programs +from binary file and several instructions - TAX, TAY and NOP.

+ +

I think gasm will be made for 6502 firstly, because it is easier then x86 and it would help in +testing yemu.

+ +

I was trying to make some daily notes in Org Roam (and moved devlog notes there), but it wasn’t +very success, but I hope to do it more often :)

+ +

Also I have registered #gru channel on libera, so you can join us also on libera.chat :)

+GRU Devlog 6 - yemu, published gxt and interrupts working in Orion +

+ +
September 05, 2021 — +G1n +
+ + +

This week I have published gxt, but it currently works as more (only down scrolling). +Also it has a lot of of runtime error (Segmentation fault and others).

+ +

I have started working on yemu - Yet another EMUlator. It currently supports only 6502 +proccessor with tiny number of instructions (LDA, LDX and LDY)

+ +

Today we have fixed interrupts in Orion and now I can implement timer, paging, keyboard +and a lot of other things (thanks to quinn and smlckz from tilde.chat)
