- Complete function:
There was lots of unnecessary C code for the complete function, therefore
moving it to Lua and use all the plumbing we have in place to retrieve the
results.
- Moving the module:
It's important we keep nvim lua modules name spaced, avoids conflict with
plugins, luarocks, etc.
- Refactor health.vim to discover lua healthcheck in the runtime
directories lua/**/health{/init}.lua
- Support healthchecks for lua submodules e.g :checkhealth vim.lsp and
also support wildcard "*" at the end for all submodules
:checkhealth vim*
- Refactor health.vim to use variable scope instead of output capturing
- Create health.lua module to wrap report functions and future
extensibility.
- Move away from searching just in the runtimepath, use
`nvim_get_runtime_file` due to #15632
Example:
Plugin linter in rtp can declare it's checkhealts in lua module
`lua/linter/health{/init}.lua` that returns a table with a method
"check" that when executed calls the report functions provided by the
builtin lua module require("health").
The plugin also has a submodule `/lua/linter/providers` in which it
defines `/lua/linter/providers/health{/init}.lua`
This plugin healthcheck can now be run by the ex command:
`:checkhealth linter linter.providers`
Also calling all submodules can be done by:
`:checkhealth linter*
And "linter" and "linter.provider" would be discovered when:
`:checkhealth`
