:cat2: vimCATS :book:
A CLI to generate vimdoc from LuaCATS. Forked from lemmy-help.
### What?
`vimcats` is a LuaCATS parser as well as a CLI
which takes that parsed tree and converts it into vim help docs.
### Installation
[](https://repology.org/project/vimcats/versions)
- Using `cargo`
```bash
cargo install vimcats --features=cli
```
### LuaCATS
To properly generate docs you should follow the luaCATS spec.
The parser is capable of parsing most (not all) of the LuaCATS syntax.
You can read the following doc which can give you an idea on how to
properly write LuaCATS annotations.
- [Writing LuaCATS annotations](./luaCATS.md)
### Usage
Using the CLI is simple just give it the path to the lua files;
it will parse them and prints help doc to `stdout`.
```bash
vimcats /path/to/{first,second,third}.lua > doc/PLUGIN_NAME.txt
```
### CLI
```text
vimcats
USAGE:
vimcats [FLAGS] [OPTIONS] ...
ARGS:
... Path to lua files
FLAGS:
-h, --help Print help information
-v, --version Print version information
-M, --no-modeline Don't print modeline at the end
-f, --prefix-func Prefix function name with ---@mod name
-a, --prefix-alias Prefix ---@alias tag with return/---@mod name
-c, --prefix-class Prefix ---@class tag with return/---@mod name
-t, --prefix-type Prefix ---@type tag with ---@mod name
--expand-opt Expand '?' (optional) to 'nil' type
OPTIONS:
-i, --indent Controls the indent width [default: 4]
-l, --layout Vimdoc text layout [default: 'default']
- "default" : Default layout
- "compact[:n=0]" : Aligns [desc] with
and uses {n}, if provided, to indent the
following new lines. This option only
affects ---@field and ---@param tags
- "mini[:n=0]" : Aligns [desc] from the start
and uses {n}, if provided, to indent the
following new lines. This option affects
---@field, ---@param and ---@return tags
USAGE:
vimcats /path/to/first.lua /path/to/second.lua > doc/PLUGIN_NAME.txt
vimcats -c -a /path/to/{first,second,third}.lua > doc/PLUGIN_NAME.txt
vimcats --layout compact:2 /path/to/plugin.lua > doc/PLUGIN_NAME.txt
NOTES:
- The order of parsing + rendering is relative to the given files
```

### Nix flake
This project provides a flake so you can use it with frameworks
like [git-hooks.nix](https://github.com/cachix/git-hooks.nix).
Here is basic example:
> [!NOTE]
>
> You will likely want to ajust the flake to be used
> with multiple systems.
```nix
{
inputs = {
git-hooks.url = "github:cachix/git-hooks.nix";
vimcats.url = "github:mrcjkb/vimcats";
};
outputs = {
self,
nixpkgs,
git-hooks,
vimcats,
...
}: let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
docgen = final.writeShellApplication {
name = "docgen";
runtimeInputs = [
inputs.vimcats.packages.${final.system}.default
];
text = ''
mkdir -p doc
vimcats [args] > doc/.txt
'';
};
git-hooks-check = git-hooks.lib.${system}.run {
src = self;
hooks = {
docgen = {
enable = true;
name = "docgen";
entry = "${pkgs.docgen}/bin/docgen";
files = "\\.(lua)$";
pass_filenames = false;
};
};
};
in {
devShells.${system}.default = {
pkgs.mkShell {
buildInputs = [
docgen
];
shellHook = ''
# Installs a docgen pre-commit hook
${git-hooks-check.shellHook}
'';
};
};
checks.${system} = {
inherit git-hooks-check;
};
};
}
```
