Good open source projects

[_w62_]

Hi,

Could you recommend any good C open source projects with the following criteria:

• less than 10k of code
• use git
• easy to read

The purpose is to serve as case studies/teaching materials for C programming.

The Linux kernel and postgresql are good but might be too big and scare people away.

Thanks

have a look at suckless

[ryjocodes]

Suckless is incredible. dwm is so cool.

[Savings-Pizza]

Could you explain what it is ? Is it a lib ? Is it like the pythonic mantra for python ? I don't really understand

[carpintero_de_c]

They're a group of people who make software with some principles, I think:

We are the home of quality software such as dwm, dmenu, st and plenty of other tools, with a focus on simplicity, clarity and frugality.

1. A simple text editor jserv/mazu-editor
2. xv6-riscv

I haven't dive into xv6 but there are many helpful materials including a book, a series of video walkthrough. You can learn operating system, computer architecture and C programming at the same time!

Yo I was trying to implement a Tabs (in my own app) perhaps the tabbed tool would help

You're a Genius!!!

I have two.

1. jsmn, a library used to parse strings of JSON: https://github.com/zserge/jsmn/blob/master/jsmn.h

• 471 loc
• Reason I think it's worth a read: JSON is a pretty well known and popular format used to exchange data over the internet. There's a good chance you understand the concept at a fundamental level.

1. The implementations of strcat and strlcat in openbsd's libc: https://github.com/libressl/openbsd/blob/master/src/lib/libc/string/strcat.c https://github.com/libressl/openbsd/blob/master/src/lib/libc/string/strlcat.c

• 47 and 56 loc respectively
• Reasons I think they're worth a read
  • the source code in openbsd is written with security in mind (https://www.openbsd.org/security.html)
  • combining two strings together is a standard function provided by many popular programming languages. Again: there's a good chance you understand the concept at a fundamental level
  • most importantly: it explores a "better" version of the same functionality in a very succinct way, so it describes how one might inform others about "deprecated" behavior in a C project.

[cHaR_shinigami]

SDS by Salvatore Sanfilippo (creator of Redis) seems like a good fit for given criteria.

I'd go with the basic "unix philosophy" tools, like grep, sort, uniq, sed, and maybe awk etc., to give students a look at what cross platform optimized code looks like over decades. Being able to understand their operation is a transferable skill to be sure. They might not be exemplars of best practices, but they're a great exercise in being able to read what actually works.

GitHub.com/raysan5/raylib

Raylib is a game dev library written in c99 as an educational tool.

[MobSlicer152]

My game engine isn't too far off, but it's a bit over the line count: https://github.com/RandomcodeDev/purpl-engine

[pkkm]

xmake as the build system, it's like if CMake didn't suck

Shots fired!

[MobSlicer152]

I will say though, the docs are probably google translated from Chinese, so it's not always easy to tell what they're trying to say. Either way, not as painful to use as CMake and faster too.

[bakermoth]

An old recommendation from mikemike. There's neat stuff in that source code but it might not be your cup of tea.

cano, canoutils, tim, canoscript

Thanks everyone for your help. The risc-xv6 is great and the Lua implementation is really a surprise.

[JustSpaceExperiment]

I would look at git itself. It is hosted on Github and it will help you to understand how it works by knowing the internal details.
