merge several "yazi.toml" files

[teto]

Please describe the problem you're trying to solve

I generate part of my config with nix https://nixos.org/. It has several advantages, one of which is for general toggle of a plugin.
For instance I have a nix setting yazi.enableOuchPlugin = true that enables the yazi plugin https://github.com/ndtoan96/ouch.yazi:
it puts the plugin files where expected (in ~/.config/yazi/plugins/ouch.yazi), makes "ouch" available to the plugin and enables the config advised in the plugin, i.e. the previewers and loaders.

The drawback is that generating ~/.config/yazi/yazi.toml via nix, the file becomes read-only and any change to the config becomes bothersome because it takes several seconds for nix to regenerate the config.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

What I try to when possible do is to get the best of both worlds by merging:

• a configuration generated by nix
• an imperative configuration I can quickly edit/save/restart the software

Now I dont know how to do this with yazi, I dont think it's possible ?

Outside of my specific nix usecase, maybe this feature could be used by plugins to embed their own configuration ?
The possible ways to do it I could think of:

1. add an "include" directive in yazi.toml
2. have a "config.d" folder like for ssh, where all files in this folder are loaded
3. have plugins embed their own yazi.toml that can be merged
4. have a lua API to load the different configuration files (keymap/yazi.toml etc)

4. is probably the easiest to develop and integrate

I think introducing config merging for a performance-first file manager is a bit overkill (it will require reading more files and doing more merges), and it could also cause more confusion - I've explained my thoughts in more detail in another issue here, #989 (comment)

is it possible via the API to add previewers / loaders ? I could live with that generating a script that changes my config afterwards.
