 ## Features
 
-* Builds **FAST**.
+* Simple as C, you only need a C compiler and standard unix libraries to build this.
-  * `a32e4a5`:
-    * `2.830s`: laptop, -O3, -j2, `AMD E-450 APU with Radeon(tm) HD Graphics`
-    * `0.172s`: desktop, -O3, -j12, `AMD Ryzen 5 5600G with Radeon Graphics`
-  * `663427e`:
-    * `0.085s`: desktop, -O0, `AMD Ryzen 5 5600G with Radeon Graphics`
-    * `0.009s`: desktop, -O0, CC=tcc, `AMD Ryzen 5 5600G with Radeon Graphics`
-* Works everywhere you can get gcc to compile.
-* Fast and possibly efficient.
 * Fully customizable, from strings, including action keys, to colors (I hope you know ansi escape codes)
 * Automatically detects xorg and wayland sessions, plus allowing to launch the default user shell (if enabled in config)
 * Starts with many init systems (systemd, dinit, runit, openrc and s6).
 
-## WIP
-
-* Desktop's file `TryExec` key.
-* Save last selection.
-* Show/hide passwd switch.
-* Long sessions, strings, usernames, passwords... they will just overflow or fuck your terminal, I know it and I don't know if I'll fix it.
-* UTF characters or any multi-byte character, not yet supported properly, everything treats characters as a single byte, some chars might work or not depending on the context, but it's not designed to.

 ### Arguments
 
-If a single argument is provided (don't even do `--` or standard parsing...), it passes that argument to `chvt` on startup, used (at least) by most service files.
+If a single argument is provided (don't even do `--` or standard unix parsing...), it switches to said tty number at startup. Used (at least) by most service files.
 
 ### Program
 
-On top of pure intuition:
+Base (mostly intuitive):
 
-* You can change focus of session/user/passwd with up/down arrows.
+* Use arrow keys to navigate the inputs and type over any of them to override the default value.
-* In case arrow keys do nothing on the focused input (Either is empty text or doesn't have more options), it tries to change session and if there's only one session it changes user.
+* Enter will just attempt to login.
-* Typing anything will allow to put a custom user or shell command too, you can use arrow keys to move.
+* If you are focused on an edited input, horizontal arrow keys will attempt to move across the text just as expected.
-* ESC and then left/right arrows will force to change the option of the focused input, useful if you're editing the current input and arrow keys just move.
+
-* Editing a predefined option on a user or a shell session, will put you in edit mode preserving the original value, other cases start from scratch.
+On top of that:
+
+* Using the horizontal arrow keys if the focused input is not in text mode or the movement would overflow the input. It will try to change in such direction the option of session or the user.
+* Pressing <kbd>ESC</kbd> and then horizontal arrows will force to change the option of the focused input even if it's in edit mode.
+* Editing an option on a user or a shell session will put you in edit mode appending after the original value.
 
 # Requirements
 
-* A computer with unix based system.
-* That system should have the resources necessary 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 automatically, make sure `gcc` and `mkdir -p` work as expected).
-* PAM, used for user authentication, just what `login` or `su` use internally. Don't worry, it's surely pre-installed.
+* A compiler like `cc`, `gcc` or `clang`. Make sure to use the desired `CC=<compiler>` on the `make` command.
+* PAM library, used for user authentication, just what `login` or `su` use internally. Don't worry, it's surely pre-installed.
 
 # Installation

 # Configuring
 
-Copy any `.ini` file from [`themes/`](./themes/) (`default.ini` will always be updated) to `/etc/lidm.ini` and/or configure it to your liking. Also, don't place empty lines (for now). You can also set `LIDM_CONF` environment variable to specify a config path.
+Copy any `.ini` file from [`themes/`](./themes/) (`default.ini` will always be updated) to `/etc/lidm.ini` and/or configure it to your liking. You can also set `LIDM_CONF` environment variable to specify a config path.
 
-Configured colors are just gonna be put inside `\x1b[...m`, ofc you can add an 'm' to break this and this can f\*ck up really bad or even make some nice UI effect possible, 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. But please, keep in mind this might break easily.
+The format attempts to mimic the TOML format. Escape sequences like `\x1b` are allowed as well as comments and empty lines.
 
-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).
+Colors are gonna be put inside `\x1b[...m`, if you don't know what this is check [an ANSI table](https://gist.github.com/JBlond/2fea43a3049b38287e5e9cefc87b2124). Mind that `\x1b` is the same as `\e`, `\033` and several other representations.
+
+> [!NOTE]
+> The default `fg` style should disable decorators set up in other elements (cursive, underline...). It's just adding 20 to the number, so if an underline is 4, disabling it is done with 24.
 
 > [!TIP]
 > If you don't like seeing an element, you can change the fg color of it to be the same as the bg, making it invisible.

-# Backstory
+# Inspiration
 
-Summer travelling to visit family with an old laptop that barely supports x86\_64, and ly recently added some avx2 instructions I think (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).
+This project was started after facing some issues building [ly](https://github.com/fairyglade/ly) on an ancient laptop, the UI is heavily inspired by it.
 
-I spedrun it in roughly 3 days 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, crashing the system due to a off-by-one error, but pretty consistent otherwise (probably).
+For this reason the project's philosophy is to be simple and minimal, such that even prehistoric hardware is capable of running it.
 
-The name is just ly but 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.
+I forgot what exactly the name came from, but it surely was a mix of a few things so:
+
+* Obviously it's inspired by `ly`. `ly-dm` leads to "lydm".
+* Wow make "lydm" simple with a "y" → "i" transformation.
+* Associate it with the "i" in s**i**mple and other display managers like **Li**ghtDM.
+* And the **la**ptop this project started in has a **lid**.

+.SH THEMES
+There are themes you can take as reference or simply copy in \fBthemes/\fP, no need to tackle the config yourself. It's good to give this a read however.
+
 .SH DESCRIPTION
-The \fI/etc/lidm.ini\fP file specifies all the configuration for lidm, including theme colors.
+The \fI/etc/lidm.ini\fP file specifies all the configuration for lidm, including theme colors. It's also possible to override this path with the \fILIDM_CONF\fP environment variable.
 
-The config parser is very primitive still, so the file only consists of \fBkey/value\fP pairs separated by \fB' = '\fP (yes, the surrounding spaces are necessary). It will also not warn if the config is invalid.
+The configuration aims to mimic a toml syntax but it's not 100% compatible with it. It's grouped in tables and takes key/value pairs parsed in different modes depndending on the type. Comments and empty lines are allowed as well as surrounding whitespace at the edges of the line and the equals sign.
 
-You can't escape characters with \fB'\\'\fP, but the program reads until the end of line, so you can put any raw bytes there.
+Values can be of these types:
+.TP
+\fBSTRING\fP

+understand how they can be related to the rest of the project and what side
+changes it can require.
+
+# Structure
+
+The file structure is very simple, you have `.c` files in `src/` with their
+header `.h` counterpart in `include/`, they are listed in the `Makefile` and
+built all together on the same layer.
+
+Each file contains functions aimed to provide some specialized behavior, they
+tend to follow a common prefix (like `vec_` for vector functions) to avoid name
+collisions with themselves.
+
+## Important Files
+
+The `main.c` of course provides the entry point of the program, then each file
+has special functionality, but a special one is `util.h`, is linked with almost
+every file and provides some shared utilities to dealing with UTF-8, dynamic
+Vectors and other stuff.
+
+`log.c` is also an important file as it provides logging utilities for
+debugging, there's no need to deal with it's initialization, it behaves just
+like standard printing utilities but integrated into the configured logfile.
+
+# Debugging
+
+The log module can be easily used by just setting up the `LIDM_LOG`
+environmental variable to the logs output path.
+
+# Header Files
+
+But what if you create a new file? It's important that the definitions are only
+evaluated once by the compiler, even if they are included by several files. For
+this, you can use this simple trick (assume this is for a file named
+`mylib.h`):
+
+```h
+#ifndef MYLIBH_
+#define MYLIBH_
+
+// library contents
+// ...
+
+#endif
+```
+
+It's also a good idea to include brief comments above functions if it's not
+evident what they do and name all parameters.
+
+# Nullability Checks
+
+Nullability checks are not really enforced in the code but it's never a bad
+idea to include them, however, `gcc` doesn't support them under certain
+conditions.
+
+For this you can use `NULLABLE`, `NNULLABLE` and `UNULLABLE` macros from
+`"macros.h"` to conditionally include `_Nullable`, `_Nonnull` and
+`_Null-unspecified` respectively.
+
+# Handling & Support
+
+Every function should properly handle allocation failures (avoid them with
+stack arrays where possible), support UTF-8 strings, use the `log` module
+instead of printing to stdout (messing with the state of the ui) and free all
+lost memory (if it can be lost before reaching the final stage where it execs
+another program, I'm fine with not freeing memory still reachable at the end).
+
+# Code format, style and linting
+
+Be reasonable and follow `clang-format` and `clang-tidy` rules. `clang-tidy`
+can be quite pedantic with the current primitive rules, so feel free to use
+`LINTIGNORE` or discuss if said rule should be enforced in first place.
+
+Also avoid grammar typos and for shell scripts use `shellcheck`, you can run
+this checks with `make pre-commit` if you have the required tools.
+
+# Documentation
+
+Please, also check if there's documentation related to the feature/changes you
+are implementing, could be on markdown or manpages, if there is and you have
+some spare time, it's really helpful to update it; although not enforced.
