nvim

Using Pascal Language Server in Neovim

Assuming you have already compiled the server. If you haven't, do that first.

• Install nvim-lspconfig
• Copy pascal.lua into ~/.local/share/nvim/site/pack/vendor/opt/nvim-lspconfig/lua/lspconfig/ (yes, quite a mouthful)
• Make sure pasls is in PATH (or edit pascal.lua to use an absolute path pointing to the executable)
• Enable pasls in your init.vim:

  packadd nvim-lspconfig
  lua require'lspconfig'.pascal.setup{}

Note that this will not by itself enable any features as those are managed by separate plugins in Neovim.

Example config

The following example uses completion-nvim for code completion.

packadd nvim-lspconfig
packadd completion-nvim

lua << EOF
local nvim_lsp = require('lspconfig')

local on_attach = function(client, bufnr)
  local function buf_set_keymap(...) vim.api.nvim_buf_set_keymap(bufnr, ...) end
  local function buf_set_option(...) vim.api.nvim_buf_set_option(bufnr, ...) end

  require'completion'.on_attach(client, bufnr)

  -- Enable completion triggered by <c-x><c-o>
  buf_set_option('omnifunc', 'v:lua.vim.lsp.omnifunc')

  -- Mappings.
  local opts = { noremap=true, silent=true }
  buf_set_keymap('n', 'gD', '<cmd>lua vim.lsp.buf.declaration()<CR>', opts)
  buf_set_keymap('n', 'gd', '<cmd>lua vim.lsp.buf.definition()<CR>', opts)
end

require'lspconfig'.fpc.setup{on_attach=on_attach}

" Make code completion less intrusive
let g:completion_enable_auto_popup = 0
let g:completion_enable_auto_signature = 1

" Invoke code completion with <Ctrl>+<Space>
imap <c-space> <Plug>(completion_trigger)

EOF
