Problem: Health check floating window gets closed when pressing 'gO' to show TOC because LSP floating preview system auto-closes on BufEnter events triggered by :lopen. Solution: Temporarily disable BufEnter event for the current window during TOC operations and adjust window layout to prevent overlap.

--- @brief

|
|
--- vim.health is a minimal framework to help users troubleshoot configuration and any other
|
|
--- environment conditions that a plugin might care about. Nvim ships with healthchecks for
|
|
--- configuration, performance, python support, ruby support, clipboard support, and more.
|
|
---
|
|
--- To run all healthchecks, use:
|
|
--- ```vim
|
|
--- :checkhealth
|
|
--- ```
|
|
--- Plugin authors are encouraged to write new healthchecks. |health-dev|
|

|
|
--- COMMANDS *health-commands*
|
|
---
|
|
--- *:che* *:checkhealth*
|
|
--- :che[ckhealth] Run all healthchecks.
|
|
--- *E5009*
|
|
--- Nvim depends on |$VIMRUNTIME|, 'runtimepath' and 'packpath' to
|
|
--- find the standard "runtime files" for syntax highlighting,
|
|
--- filetype-specific behavior, and standard plugins (including
|
|
--- :checkhealth). If the runtime files cannot be found then
|
|
--- those features will not work.
|
|
---
|
|
--- :che[ckhealth] {plugins}
|
|
--- Run healthcheck(s) for one or more plugins. E.g. to run only
|
|
--- the standard Nvim healthcheck: >vim
|
|
--- :checkhealth vim.health
|
|
--- <
|
|
--- To run the healthchecks for the "foo" and "bar" plugins
|
|
--- (assuming they are on 'runtimepath' and they have implemented
|
|
--- the Lua `require("foo.health").check()` interface): >vim
|
|
--- :checkhealth foo bar
|
|
--- <
|
|
--- To run healthchecks for Lua submodules, use dot notation or
|
|
--- "*" to refer to all submodules. For example Nvim provides
|
|
--- `vim.lsp` and `vim.treesitter`: >vim
|
|
--- :checkhealth vim.lsp vim.treesitter
|
|
--- :checkhealth vim*
|
|
--- <
|
|
---
|
|
--- USAGE *health-usage*
|
|
---
|
|
--- Local mappings in the healthcheck buffer:
|
|
---
|
|
--- q Closes the window.
|
|
---
|
|
--- Global configuration:
|
|
--- *g:health*
|
|
--- g:health Dictionary with the following optional keys:
|
|
--- - `style` (`'float'|nil`) Set to "float" to display :checkhealth in
|
|
--- a floating window instead of the default behavior.
|
|
---
|
|
--- Example: >lua
|
|
--- vim.g.health = { style = 'float' }
|
|
---
|
|
---</pre>
|
|
---
|
|
--- Local configuration:
|
|
---
|
|
--- Checkhealth sets its buffer filetype to "checkhealth". You can customize the buffer by handling
|
|
--- the |FileType| event. For example if you don't want emojis in the health report:
|
|
--- ```vim
|
|
--- autocmd FileType checkhealth :set modifiable | silent! %s/\v( ?[^\x00-\x7F])//g
|
|
--- ```

|
--- Create a healthcheck *health-dev*
|
|
---</pre>
|
|
---
|
|
--- Healthchecks are functions that check the user environment, configuration, or any other
|
|
--- prerequisites that a plugin cares about. Nvim ships with healthchecks in:
|
|
--- - $VIMRUNTIME/autoload/health/
|
|
--- - $VIMRUNTIME/lua/vim/lsp/health.lua
|
|
--- - $VIMRUNTIME/lua/vim/treesitter/health.lua
|
|
--- - and more...
|
|
---
|
|
--- To add a new healthcheck for your own plugin, simply create a "health.lua" module on
|
|
--- 'runtimepath' that returns a table with a "check()" function. Then |:checkhealth| will
|
|
--- automatically find and invoke the function.
|
|
---
|
|
--- For example if your plugin is named "foo", define your healthcheck module at
|
|
--- one of these locations (on 'runtimepath'):
|
|
--- - lua/foo/health/init.lua
|
|
--- - lua/foo/health.lua
|
|
---
|
|
--- If your plugin also provides a submodule named "bar" for which you want a separate healthcheck,
|
|
--- define the healthcheck at one of these locations:
|
|
--- - lua/foo/bar/health/init.lua
|
|
--- - lua/foo/bar/health.lua
|
|
---
|
|
--- All such health modules must return a Lua table containing a `check()` function.
|
|
---
|
|
--- Copy this sample code into `lua/foo/health.lua`, replacing "foo" in the path with your plugin
