"Run foo" is enough, don't need "for more information".

The message should include the name

It could be a good idea to print the provider name in the message. Provider for NAME not found. Run :checkhealth provider

Executing `:python`, and similar commands that rely on `eval_call_provider()`, while the accompanying provider it not available, leads to this error message: E117: Unknown function: provider#python#Call This doesn't say much to a user. Since we introduced `:checkhealth` for this very reason, we now point to it for further diagnosis. Fixes neovim#3577

Thanks @mhinz , great to finally see this fixed! |
In Vim (and some vestigial parts of Nvim) E319 a placeholder for ex_ni commands, i.e. commands that are only available in certain builds of Vim. That is obviously counter to Nvim's goals: all Nvim commands are available on all platforms and build types (the remaining ex_ni commands are actually just missing providers). However, the runtime provider for a given feature may be missing, and in that case it makes sense to attach E319 to the error message. ref neovim#9344 ref neovim#3577

That is obviously counter to Nvim's goals: all Nvim commands are available on all platforms and build types (the remaining ex_ni commands are actually just missing providers). We need an error id for "missing provider", so it makes sense to use E319 for that purpose. ref neovim#9344 ref neovim#3577
