vim-healthcheck is a polyfill plugin for Vim to use a health-check feature in Neovim. Neovim's health-check feature is a minimal framework to help with troubleshooting user configuration. vim-healthcheck provides the same feature for Vim.

Plugin authors can write health-checks for their plugins using the APIs. And plugin users can check if the installation is healthy. By this polyfill, plugin authors can write common health-checks for both Neovim and Vim. And plugin users can check their configuration using the health-checks which was written for Neovim. It would be useful for troubleshooting or triaging issues.

This plugin is just a port of Neovim's health-check implementation.

Instead of Neovim's standard :checkhealth command, it provides :CheckHealth command on Vim. If no argument is given, it runs all health-checks and show the results.

:CheckHealth

If some plugin names are specified as arguments, it runs health-checks for them.

:CheckHealth {plugin1} {plugin2} ...

For example, :CheckHealth vim runs health-checks for Vim itself.

To know the detail of the command behavior or to know how to implement health-checks for your plugins, please read a help document.

:help health

If you use a plugin manager, please follow the instruction. Please note that this plugin is needed only on Vim because Neovim supports health-check feature by default.
