lidm

Lidm is a really light display manager made in C, highly customizable and held together by hopes and prayers 🙏

this is shown as in a terminal emulator, actual linux console doesn't support as much color and decorations

Features

• Builds fast af
• Works everywhere you can get gcc to compile
• Fast and possibly efficient
• Fully customizable, from strings to colors (I hope you know ansi escape codes), to action buttons
• Automatically detects xorg and wayland sessions, plus allowing to launch the default user shell (if enabled in config)

WIP

• Save last selection
• Config parsing, it's fully customizable, but everything hardcoded for now :)
• Long sessions, strings, usernames, passwords... they will just overflow or f*ck your terminal, I know it and I don't know if I'll fix it.

Forget it

• Any kind of arguments
• UTF characters, I'm using strlen() and treating characters as per byte basis, UTF-8 chars might work or not

Caution

(they should add > [!DISCLAIMER] fr) I wrote this readme with the same quality as the code, behing this keyboard there's half a brainrotcell left writing what it remembers of this program, so don't take this to seriously, I'm typing as I think without filter lol, but the program works, or should. Also, about any "TODO" in this readme (or the code), I didn't forget finishing it, I actually don't care. And, references to code anything are likely to be outdated, check the commit history to know what I was refering to exactly if you care.

Ideology

We all know that the most important thing in a project is the ideology of the author and the movements he wants to support, so #stopchatcontrol.

Backstory

I went into summer travel to visit family with an old laptop that barely supports x86_64, and ly recently added some avx2 instructions I think (I just get invalid op codes), manually building (any previous commit too) didn't work because of something in the build.zig file, so out of boredom I decided to craft up my own simple display manager on the only language this thing can handle, ✨C✨ (I hate this and reserve the right for the rust rewrite, actually solid).

I spedrun it, basically did in in 3 days on the same couch on unhelty back positions (even worse) while touching some grass (:o), and I'm bad af in C, so this is spaghetti code on another level. I think it doesn't do almost anything unsafe, I mean, I didn't check allocations and it's capable of reallocating memory until your username uses all memory and crashes the system due to a off by 1 error, but pretty consistent otherwise (probably).

The name is just ly byt changing "y" with "i", that had a reason but forgot it, (maybe the i in simple), so I remembered this sh*tty laptop with a lid, this thing is also a display manager (dm, ly command is also ly-dm), so just did lidm due to all that.

Btw, this laptop is so bad that I can't even render markdown in reasonable time, I'll just push this and fix render issues live :)

Index

(TODO, VSC(odium) does this automatically, I'm on nvim rn 😎)

Requirements

• A computer with unix based system.
• That system should have the resources neccessary for this program to make sense (sessions, users...)
• A compiler (optional, you can compile by hand, but I doubt you want to see the code)
• Make (also optional, but does things atomatically, make sure gcc and mkdir -p work as expected)

Compiling

make # 👍

Configuring

Ugh, config will be a straigh copy of config defaults to /etc I think, there's no config yet :P and you need to enable the service, just do what ly does (I'm doing this on dinit, all init systems should be supported).

Also configurable colors are just gonna be put inside \x1b[...m, ofc you can add an m to break this and this can f* up really bad or even make some nice UI effect possible, but please don't, you should also be able to embed the \x1b byte in the config as I won't parse escape codes, I think that the parser is just gonna grab anything in the config file from the space after the = (yes, I'ma enforce that space, get good taste if you don't like it) until the newline, you can put any abomination in there.

Btw, the default fg style should disable decorators set up in other elements (cursive, underline... it's just adding 20 to the number btw, so if cursive is 4 (iirc), disabling it is 24).

Contributing

Don't do this to yourself, but you can ofc, you can also fork or whatever (make sure to comply with GNU's GPLv3), but I want to do the rust rewrite 😡 (after it, I'll leave this around in case somebody with ancient hardware needs it, or if somebody wants to port it for a microwave...)

This is also GPLv3 bcs I was too lazy to look for the "do anything I don't care" license, also it's funny legally trapping people into FOSS. EDIT: just realized ly uses it and I coudl've just copied it :(, idk how bad GPLv3 respect to changing license and I could rebase but that never goes well, so I'll consult my lawyer (chatGPT) later.

Contributors

Special thanks to:

• ChatGPT, in times of slow laptops where pages take ages to load, a single tab connected to a bunch of burning cloud GPUs feeding corporate hype is all you need to get quick answers for your questions, as long as you know how to filter AI crap ofc.
• My lack of gf, can't imagine this project being possible if somebody actually cared about me daily.

Oh, an actual recommendation, if you don't like a element you can change the fg color of it to be the same as the bg.

Congrats if you've managed to read through all this.
