C/C++ Grammer-related crash when opening file

[bicyclespokesperson]

Describe the bug

When I open a C++ file, I get a crash with the following error message:

Error detected while processing BufReadPost Autocommands for "*":

I cannot reference text objects in C/C++, though I can reference them in other languages such as Python.

It appears to be related to the C grammar file (which is imported by the C++ grammar file): If I comment out this section of the file, the crash goes away and I can reference the C++ text objects correctly (with, for example, vaf to select a function).

; (if_statement
;   alternative: (else_clause (compound_statement . "{" . (_) @_start @_end (_)? @_end . "}"
;   (#make-range! "conditional.inner" @_start @_end)))) @conditional.outer

To Reproduce

Opening any C or C++ file in vim can cause the crash for me.

I'm using the following config (copy/pasted from the README). I'm using lunarvim 1.3, (a wrapper layer around neovim 0.9), so this config is in ~/.config/lvim/config.lua

lvim.plugins = {
  -- {example/plugin}
  {
    "nvim-treesitter/nvim-treesitter-textobjects",
    after = "nvim-treesitter",
    config = function()
      require 'nvim-treesitter.configs'.setup {
        textobjects = {
          select = {
            enable = true,

            -- Automatically jump forward to textobj, similar to targets.vim
            lookahead = true,

            keymaps = {
              -- You can use the capture groups defined in textobjects.scm
              ["af"] = "@function.outer",
              ["if"] = "@function.inner",
              ["ac"] = "@class.outer",
              -- You can optionally set descriptions to the mappings (used in the desc parameter of
              -- nvim_buf_set_keymap) which plugins like which-key display
              ["ic"] = { query = "@class.inner", desc = "Select inner part of a class region" },
              -- You can also use captures from other query groups like `locals.scm`
              ["as"] = { query = "@scope", query_group = "locals", desc = "Select language scope" },
            },
            -- You can choose the select mode (default is charwise 'v')
            --
            -- Can also be a function which gets passed a table with the keys
            -- * query_string: eg '@function.inner'
            -- * method: eg 'v' or 'o'
            -- and should return the mode ('v', 'V', or '<c-v>') or a table
            -- mapping query_strings to modes.
            selection_modes = {
              ['@parameter.outer'] = 'v', -- charwise
              ['@function.outer'] = 'V', -- linewise
              ['@class.outer'] = '<c-v>', -- blockwise
            },
            -- If you set this to `true` (default is `false`) then any textobject is
            -- extended to include preceding or succeeding whitespace. Succeeding
            -- whitespace has priority in order to act similarly to eg the built-in
            -- `ap`.
            --
            -- Can also be a function which gets passed a table with the keys
            -- * query_string: eg '@function.inner'
            -- * selection_mode: eg 'v'
            -- and should return true of false
            include_surrounding_whitespace = true,
          },
        },
      }
    end,
    dependencies = "nvim-treesitter/nvim-treesitter",
  },
}

Expected behavior

There should be no crash, the file should open and I should be able to reference C++ text objects.

Also experience this error, also confirm that commenting out those lines in textobjects.scm fixes

[kiyoon]

I personally don't have this problem.

@dwcoates Are you also using LunarVim?

I think what's likely that happened was that C parser has been updated, and your nvim-treesitter version is old. This used to happen when you use LunarVim because they snapshot the old version and restrict it from being updated.

@theHamsta Can you confirm this? @mortezadadgar Anything you know why this happens?

[bicyclespokesperson]

Thanks for the quick reply! It seems like this is indeed the case. The last commit to update the C parser was a178586, and I can confirm that e1e670a (the commit before a178586) works for me. Unfortunately I can't update nvim-treesitter without breaking some other lunarvim stuff, but I'm happy to use e1e670a for now

[kiyoon]

That's good to know! Until LunarVim officially update nvim-treesitter it will be good to snapshot this plugin as well.
