Blink

Reopens #10

---

Adds blink.cmp as the default completion engine

TODO

• Add initial config that matches current nvim.cmp config
• Figure out how to add other nvim.cmp sources like emoji, calc, etc
• Wait for cmdline support, that's a deal breaker for me
• Unstable suggestions behavior on path source. Figure this out or wait until it's resolved (see this issue Path suggestions missing when cursor is followed by any other character Saghen/blink.cmp#959 or this discussion Accepting items in vtsls Saghen/blink.cmp#884)

Findings

1. calc can be setup through the compatibility layer:

return {
  'saghen/blink.cmp',
  version = 'v0.*',
  dependencies = {
    'hrsh7th/cmp-calc',
    {'saghen/blink.compat', version = '*', lazy = true, opts = {}},
  },
  ---@module 'blink.cmp'
  ---@type blink.cmp.Config
  opts = {
    sources = {
      default = {'lsp', 'path', 'snippets', 'buffer', 'calc'},
      providers = {
        calc = {
          name = 'calc',
          module = 'blink.compat.source',
        },
      },
    },
  },
  opts_extend = {'sources.default'},
}

2. There's a source for blink and emojis: https://github.com/moyiz/blink-emoji.nvim
3. path source behavior solution is to disable use_typo_resistance for the
   time being.
