Impossible to add a custom parser about nvim-treesitter HOT 9 CLOSED

jdummy must be the name of your grammar in grammar.js. Only then tree_sitter_jdummy will end up in the compiled shared object. You can check the symbols in the parser binary with nm

from nvim-treesitter.

set ft=jdummy ?

from nvim-treesitter.

yes it is. set ft=jdummy will set the filetype of your buffer to jdummy (:help filetype)

from nvim-treesitter.

Calling this

    require "nvim-treesitter.parsers".get_parser_configs().clojure = {
        install_info = {
            url = "https://github.com/oakmac/tree-sitter-clojure",
            files = {"src/parser.c"}
        }
    }

before setup works for me.

That's nice, I also added some things too, pr to come.

from nvim-treesitter.

I'm trying to add my own parser to nvim-tree-sitter.
:TSPlaygroundToggle does not show anything.

What I did:

1. Built a custom parser, grammar.js and highlights.scm.
   No errors running the following snippet,

tree-sitter generate
tree-sitter test

2. Added the following snippet to init.vim

local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
parser_config.jdummy = {
  install_info = {
    url = <path_to_repo>,
    files = { "src/parser.c" },
    branch= 'main'
  },
  filetype = "jdummy", -- if filetype does not agrees with parser name
}

3. Installed the parsers without any errors,
   :TSInstall jdummy
   The jdummy.so is created in the /home/farzaneh/.local/share/nvim/plugged/nvim-treesitter/parser path
4. nvim test.jdummy
5. :TSPlaygroundToggle does not show anything for me.

Am I missing something?

from nvim-treesitter.

Is that a command?
Where should I run set ft=jdummy ?

from nvim-treesitter.

I took these steps:
nvim test.jdummy
:set filetype=jdummy
:TSPlaygroundToggle

an error occurred:

        vim.lua:291: in function <vim.lua:291>

Do I have to set anything else?

from nvim-treesitter.

Although the grammar name in grammar.js is jdummy,
after running nm jdummy.so, I see no tree_sitter_jdummy.
What am I missing?
