undefined symbol: tree_sitter_nu_external_scanner_create

[Priyav Shah]

After trying to manually install tree-sitter-nu i get this error:

indent-blankline: Failed to load parser for language 'nu': uv_dlopen: /home/layz/.local/share/lunarvim/site/pack/lazy/opt/nvim-treesitter/parser/nu.so: undefined symbol: tree_sitter_nu_external_scanner_create

I don't know if thats because of an incorrect installation or if there's something not quite right with tree-sitter-nu plugin

My config file is set up as follows:

local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
parser_config.nu = {
  install_info = {
    url = "https://github.com/LhKipp/tree-sitter-nu", -- local path or git repo
    files = { "src/parser.c" },                       -- note that some parsers also require src/scanner.c or src/scanner.cc
    -- optional entries:
    branch = "main",                                  -- default branch in case of git repo if different from master
    generate_requires_npm = false,                    -- if stand-alone parser without npm dependencies
    requires_generate_from_grammar = true,            -- if folder contains pre-generated src/parser.c
  },
  filetype = "nu",                                    -- if filetype does not match the parser name
}

I've installed the parser with TSInstall nu. And i've even tried TSInstallFromGrammer nu. But both don't give me any luck.

Please help 🙏

Ok i the config file to also include 'scanner.c' (didn't realize that was also there 😅 ) and the error seems to go away, however, still no syntax highlighting 😭 could that be because of nushell version?

[Leonhard Kipp]

Hi lay-z,
have you set the filetype of config.nu to be nu?

Have you seen https://github.com/lhKipp/nvim-nu. It's a plugin which sets up this grammar and makes it all work.

[Priyav Shah]

When i run :set filetype? it returns filetype=nu but still no highlighting. Maybe i'll checkout nvim-nu, perhaps will work better for me 🙏

nvim-nu worked for me! thanks @LhKipp
