# nix2lua
|
|
|
|
This is a small but functional library that converts your nix configurations
|
|
into Lua format.
|
|
|
|
This library was initially designed for my personal
|
|
[Neovim flake](https://git.pleshevski.ru/mynix/neovim).
|
|
|
|
# Installation
|
|
|
|
Add `nix2lua` as input to your `flake.nix`
|
|
|
|
```nix
|
|
{
|
|
inputs.nix2lua.url = "git+https://git.pleshevski.ru/mynix/nix2lua";
|
|
|
|
outputs = { nix2lua }:
|
|
let
|
|
luaTable = nix2lua.lib.toLua {
|
|
foo = "bar";
|
|
|
|
nvimTree.settings = {
|
|
open_on_setup = true;
|
|
renderer = {
|
|
group_empty = true;
|
|
full_name = true;
|
|
};
|
|
};
|
|
};
|
|
in luaTable;
|
|
}
|
|
```
|
|

`toLua expr`
|
|
|
|
> Returns a string containing Lua representation of `expr`. Strings, integers,
|
|
> floats, boolean, lists and sets are mapped to their Lua equivalents.
|
|
>
|
|
> Null will be skipped. This is useful when you want to use an optional value.
|
|
> To render `nil` you should use the `LuaNil` function.
|
|
>
|
|
> ```nix
|
|
> toLua { foo = "bar"; }
|
|
> toLua [ 10 "foo" [ "bar" ] ]
|
|
> ```
|
|
|
|
`LuaNil`
|
|
|
|
> Creates a type that will be mapped by the `toLua` as `nil`
|
|
>
|
|
> ```nix
|
|
> toLua LuaNil
|
|
> ```
|
|
|
|
`LuaRaw expr`
|
|
|
|
> Creates a type that instructs `toLua` not to change the passed expression
|
|
> `expr`.
|
|
>
|
|
> ```nix
|
|
> toLua (mkLuaRaw "require('bar').baz")
|
|
> ```
|
|
|
|
`mkNamedField name expr`
|
|
|
|
> Creates a type that represents a named field in the Lua table. This type
|
|
> cannot exist outside a list or set.
|
|
>
|
|
> This is useful to create table with some named fields.
|
|
>
|
|
> ```nix
|
|
> toLua [
|
|
> "foo"
|
|
> (mkNamedField "bar" "baz")
|
|
> ]
|
|
> ```
