lualine-lsp-progress

Information provided by active lsp clients from the $/progress endpoint as a statusline component for lualine.nvim.

Why?

Some LSP servers take a while to initalize. This provides a nice visual indicator to show which clients are ready to use.

Screenshot

Use

Add the component lsp_progress to one of your lualine sections.

require'lualine'.setup{
    ...
    sections = {
        lualine_c = {
            ...,
            'lsp_progress'
        }
    }
}

Installation

vim-plug

Plug 'arkav/lualine-lsp-progress'

packer.nvim

use 'arkav/lualine-lsp-progress'

Configuration

Configurable items

• Items to display and order
  • Lsp client name e.g. Rust
  • Spinner
  • Progress (individual actions undertaken by the LSP)
    • Title of action undertaken by LSP e.g. Indexing
    • Message from Lsp
    • Percentage complete
• pre and post items - before each specific lsp item display text
• Spinner
  • Symbols
  • Time between symbol update
• Color of items
• Last Message delay
  • After we receive a progress message saying an action is complete delay removing it from lualine so we can read that it's finished.
  • After the final progress message is displayed delay before no longer showing the lsp client name.
