General confusion around installation

[barathrm]

Alright, so forgive my general ignorance around neovim plugins, neorg, treesitter and the lua API which is apparently used here.

Neovim version details can be found at the bottom.

I've tried installing neorg and am apparently stuck at the step of installing treesitter. I'm generally confused around how it's installed, since it doesnt seem to be installed via a plugin-manager like packer or vim-plug, but from lua somehow. I used vim-plug, so the following is what I've tried:

Init plugin (note the comma, which is lacking from README.md and without which Plug won't pull neorg :| worth an issue ticket?)

Plug 'nvim-lua/plenary.nvim'
Plug 'vhyrro/neorg', { 'branch' : 'main' }

and config, which I put into a .vim file parsed during startup:

lua << EOF
    require('neorg').setup {
        -- Tell Neorg what modules to load
        load = {
            ["core.defaults"] = {}, -- Load all the default modules
            ["core.norg.concealer"] = {}, -- Allows for use of icons
            ["core.norg.dirman"] = { -- Manage your directories with Neorg
                config = {
                    workspaces = {
                        my_workspace = "~/neorg"
                    }
                }
            }
        },
    }


    local parser_configs = require('nvim-treesitter.parsers').get_parser_configs()

    parser_configs.norg = {
        install_info = {
            url = "https://github.com/nvim-neorg/tree-sitter-norg",
            files = { "src/parser.c", "src/scanner.cc" },
            branch = "main"
        },
    }

    require('nvim-treesitter.configs').setup()
EOF

Now, when I launch neovim I get:

Error detected while processing <$HOME>/.config/nvim/conf.d/neorg.vim:

Press ENTER or type command to continue   

So it looks like the tree-sitter lua module (?) isn't installed.

TSInstall is not available as a command. I've looked at https://github.com/nvim-neorg/tree-sitter-norg and that didn't really tell me whether I should install it separately, whether it should've been installed by the above lua somehow, or what should've happened. I don't think it's a neovim plugin. I looked at the installation page on the wiki, but that doesn't seem to mention tree-sitter. I googled tree-sitter, and apparently it's a parser generator tool and an incremental parsing library. I installed the tree-sitter binary package provided by my linux distro, but that hasn't helped.

So I'm kind of lost at what I should try now or how is this is all supposed to connect. Any pointers would be appreciated, I'd really like to try neorg.

Ah, this is a good point. You want to install the nvim-treesitter plugin alongside Neorg. If there isn't a hyperlink pointing to that repo anywhere in the README i'll be sure to add it. You don't actually need the tree-sitter binary, since the parser compilation is handled by nvim-treesitter :)

Thank you kindly! That was the missing piece. For reference, the following seems to make it work. Time to give this a trial :)

init.vim

Plug 'nvim-treesitter/nvim-treesitter'
Plug 'nvim-neorg/neorg' | Plug 'nvim-lua/plenary.nvim'

lua << EOF
    require('neorg').setup {
        -- Tell Neorg what modules to load
        load = {
            ["core.defaults"] = {}, -- Load all the default modules
            ["core.norg.concealer"] = {}, -- Allows for use of icons
            ["core.norg.dirman"] = { -- Manage your directories with Neorg
                config = {
                    workspaces = {
                        my_workspace = "~/neorg"
                    }
                }
            }
        },
    }

    local parser_configs = require('nvim-treesitter.parsers').get_parser_configs()

    parser_configs.norg = {
        install_info = {
            url = "https://github.com/nvim-neorg/tree-sitter-norg",
            files = { "src/parser.c", "src/scanner.cc" },
            branch = "main"
        },
    }
