# LSP
1. Renamed the keymaps to what I use
2. Added a custom handler for formatting files.
It checks the explicitly defined language servers passed and if they allow formatting, only then will it attempt
to format the buffer
# Complete
Completion is done by nvim-cmp. The setup for that does a few things.
1. Defines the sources to use for autocompletion:
a. LSP server
b. nvim-lua: only active in lua file I think
c. buffer: uses the current file for auto-completion (similar to default nvim behavior)
2. By default it pops up a list for auto-completion, we have that disabled.
3. When having auto-complete disabled, it takes extra steps to trigger autocomplete, due
to this we need to have it preselect the first item upon triggering autocomplete.
4. We define some custom mappings
