<p>I think this week was productive. I have done a lot of things to olibc. First I finally
|
|
implemented working FILE struct. That required to implement malloc and free, so we also
|
|
have it now! Then stdio.h was implemented. Still need to make a lot of functions, but
|
|
we already have most useful ones (for examples every C11 printf functions implemented and
|
|
fully working). Also finally stdin/stdout/stderr file descriptors working properly.</p>
|
|
|
|
<p>We have full implemented <ctype.h> header now! It wasn’t really hard.</p>
|
|
|
|
<p>This year I started from tryes to make occ - GRU C compiler (maybe it will be GRU Compiler
|
|
Collection in future). A lot of things will need to be implemented and a lot of new to know!
|
|
I hope it will be fun :)</p>
|
|
|
|
<p>Happy New 2022 Year! I hope we will make a lot of new tools this year. And more people will
|
|
join us :)</p>

<p>Happy Chirstmas! Next GRU Devlog will be next year so Happy New Year! I hope GRU will grow
|
|
and grow next year :D</p>
|
|
|
|
<p>On last Sunday we have created mailing list after devlog. Currently it is not active, but
|
|
but you can message us there - gru@lists.tildeverse.org. Then I tryed to make FILE struct
|
|
for liblinux, but it wasn’t working so it needed to be reimplemented.</p>
|
|
|
|
<p>Then youngchief submitted some changes to our webpage. Also robyndrake contributed some fixes
|
|
to coreutils.</p>
|
|
|
|
<p>Also I had implemented printf and vprintf! It currently have %c, %d, %s so it will be useful
|
|
for debugging. I have tryed to implement snprintf, but i had several problems with it so
|
|
it is not done yet.</p>
|
|
|
|
<p>Then chunk contributed logo for us! I think it looks nice!</p>
|
|
|
|
<p>Last useful thing that I have done this week is very minimal FILE, it currently just has
|
|
fd and nothing else.</p>
|
|
|
|
<p>I hope we will make more cool things and finish current projects next year!</p>
|
|
|
|
<p>Hope you liked this post! I wish everyone cool New Year!

<p>This week I also was making olibc. Now it is published! I have mostly implemented <string.h>, but there
|
|
still some funcs that require <locale.h>, so they are not implemented yet.</p>
|
|
|
|
<p>I found out why olibc wasn’t giving correct return value after program is executed. It was because
|
|
liblinux wasn’t exiting correctly, so it received some random return values from stack.</p>
|
|
|
|
<p>Also a lot of testing were done. I have found out that several functions wasn’t working correctly
|
|
and fixed it. We have shell script for testing that compares results from our libc and libc that
|
|
installed on user’s machine. It prints a diff output if test was failed. It also have other
|
|
features, if you want you can check it by running <code>test.sh --help</code> by yourself.</p>
|
|
|
|
<p>Because of it I have found that several functions were wrong implemented. But now finally
|
|
everything is working and strtok is correctly implemented!</p>
|
|
|
|
<p>Also this blog finally moved totally from my webpage, so we can move this site on different
|
|
server just by cloning it from codeberg or tildegit</p>

<p>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 <code>#include</code>. I had several other issues
|
|
with it and also fixed them.</p>
|
|
|
|
<p>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 it will be implemented. But it is already cool that we
|
|
have most of functions that should be in <string.h>!</p>
|
|
|
|
<p>Also we now have <a href="https://gru.codeberg.page">gru webpage on codeberg</a>! Maybe next week I
|
|
will move all devlogs to gru webpage so it will be easier to move.</p>

<p>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…</p>
|
|
|
|
<p>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)</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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…</p>
