GRU Devlog 20 - olibc
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
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…
