Jump to definitions WITHOUT tags, all in Lua. That's it.
No need for external programs or anything.
I have no idea how to use Neovim's tags and no idea why you need to install a separate program for to make them (not throwing shades, im genuinely dumb caveman brain and shit).
I made it for me, so it's probably not even the best implementation in the world.
I have no idea how performant it is on large codebases, so keep your expectations low pls.
7F8FNeovim v0.9.5 >= (haven't tested it on next versions).
Since it relies on pwd and on the output of ls -R,
I guess it will only work properly on Linux.
Make a '''my_ctags.lua''' file in your plugin-folder, copy paste this and your good to go.
return {
"francescoApophis/my_ctags.nvim",
lazy = false,
config = function()
local my_ctags = require("my_ctags")
vim.keymap.set('n', 'your remap', my_ctags.jump_to_def, {silent = true, noremap = true})
-- OR have two separate mappings:
-- This remap will search for all the definitions every time, this is done by default.
vim.keymap.set('n', 'your mapping', function() my_ctags.jump_to_def(true) end, {silent = true, noremap = true})
-- This remap will use the definitions found during the last search.
vim.keymap.set('n', 'your mapping', function() my_ctags.jump_to_def(false) end, {silent = true, noremap = true})
-- This will make you go to wherever you were before jumping to a definition.
-- If you press it by mistake, press it again and you will go back to where you were.
vim.keymap.set('n', 'your mapping', function() my_ctags.jump_back() end, {silent = true, noremap = true})
end
}You can specify paths (folders, specific files or both) to be ignored when searching. This means that you will not be able to jump to a definition that's located in one of this files.
Just call :require('my_ctags').set_filepaths_to_ignore(filepaths) where filepaths is
either a string or an array of strings. The next search will make sure to ignore them.
Make sure a path is a full path or that it uses the '~'.
You can see all ignored paths by calling :require('my_ctags').get_filepaths_ignored()
This is useful if you have files that unused files that may contain definitions that share the same name with other used definitions.
At the moment it only supports .c and .h, as the name implies and also because that's what I need, but there is no reason it should not be able to support other languages as well since it uses Lua's searching patterns to do its job.
If you want to you could clone the repo and modify the
my_ctags.lua file in your plugin-folder to:
return {
dir = "path/where/you/cloned/my_ctags.nvim", -- <---------
lazy = false,
...At this point just add more patterns like func or typdefed_struct in the init.lua following how the defintion of something in your target-language works.
