• vscoq.nvim uses Neovim's built-in LSP client and nvim-lspconfig. See kickstart.nvim for basic example configurations for working with LSP.
• :VsCoq command
  • :VsCoq continuous: Use the "Continuous" proof mode. It shows goals for the cursor position.
  • :VsCoq manual: Use the "Manual" proof mode (default), where the following four commands are used for navigation.
    • :VsCoq stepForward
    • :VsCoq stepBackward
    • :VsCoq interpretToEnd
    • :VsCoq interpretToPoint
  • :VsCoq panels: Open the proofview panel and query panel.
  • Queries
    • :VsCoq search {pattern}
    • :VsCoq about {pattern}
    • :VsCoq check {pattern}
    • :VsCoq print {pattern}
    • :VsCoq locate {pattern}
  • Proofview
    • :VsCoq admitted: Show the admitted goals.
    • :VsCoq shelved: Show the shelved goals.
    • :VsCoq goals: Show the normal goals and messages (default).
  • etc
    • :VsCoq jumpToEnd: Jump to the end of the checked region.

The setup() function takes a table with the followings keys:

• vscoq: Settings specific to VsCoq, used in both the client and the server. This corresponds to the "configuration" key in VsCoq's package.json.
• lsp: The settings forwarded to :help lspconfig-setup. :help vim.lsp.ClientConfig.

Some settings in VsCoq's package.json should be configured in nvim's LSP client configuration:

• "vscoq.path" and "vscoq.args" → lsp.cmd
• "vscoq.trace.server" → lsp.trace

require'vscoq'.setup {
  vscoq = {
    proof = {
      -- In manual mode, don't move the cursor when stepping forward/backward a command
      cursor = { sticky = false },
    },
  },
  lsp = {
    on_attach = function(client, bufnr)
      -- your mappings, etc

      -- In manual mode, use ctrl-alt-{j,k,l} to step.
      vim.keymap.set({ 'n', 'i' }, '<C-M-j>', '<Cmd>VsCoq stepForward<CR>', { buffer = bufnr, desc='VsCoq step forward' })
      vim.keymap.set({ 'n', 'i' }, '<C-M-k>', '<Cmd>VsCoq stepBackward<CR>', { buffer = bufnr, desc='VsCoq step backward' })
      vim.keymap.set({ 'n', 'i' }, '<C-M-l>', '<Cmd>VsCoq interpretToPoint<CR>', { buffer = bufnr, desc='VsCoq interpret to point' })
      vim.keymap.set({ 'n', 'i' }, '<C-M-G>', '<Cmd>VsCoq interpretToEnd<CR>', { buffer = bufnr, desc = 'VsCoq interpret to end' })
    end,
    -- autostart = false, -- use this if you want to manually `:LspStart vscoqtop`.
    -- cmd = { 'vscoqtop', '-bt', '-vscoq-d', 'all' }, -- for debugging the server
  },
}

NOTE: Do not call lspconfig.vscoqtop.setup() yourself. require'vscoq'.setup does it for you.

• Fancy proofview rendering
  • proof diff highlights
• Make lspconfig optional

• coq.ctags for go-to-definition.
• coq-lsp.nvim for coq-lsp client.
