# ccls extensions
To use ccls extensions, e.g., `$ccls/inheritance`, `$ccls/member`, etc., we need some hacks.
1. Copy `get_location` function from `nvim/runtime/lua/vim/lsp/buf.lua` to `~/.config/nvim/lua/get_location.lua`, and modify it to support custom parameters. An example can be found at [here](https://github.com/zsrkmyn/dotvim/blob/master/lua/get_location.lua), and you can directly use it.
2. In `init.lua`, add kepmaps on attach, e.g.,
```
local get_location = require'get_location'
require'lspconfig'.ccls.setup {
-- ...
on_attach = function(client, bufnr)
local opts = { buffer = bufnr, remap = false }
local lopts = { loclist = true }
-- ...
vim.keymap.set('n', 'gxb', function() get_location('$ccls/inheritance', {}, lopts) end, opts)
vim.keymap.set('n', 'gxB', function() get_location('$ccls/inheritance', {levels=3}, lopts) end, opts)
vim.keymap.set('n', 'gxd', function() get_location('$ccls/inheritance', {derived=true}, lopts) end, opts)
vim.keymap.set('n', 'gxD', function() get_location('$ccls/inheritance', {derived=true, levels=3}, lopts) end, opts)
vim.keymap.set('n', 'gxc', function() get_location('$ccls/call', {}, lopts) end, opts)
vim.keymap.set('n', 'gxC', function() get_location('$ccls/call', {callee=true}, lopts) end, opts)
vim.keymap.set('n', 'gxs', function() get_location('$ccls/member', {kind=2}, lopts) end, opts)
vim.keymap.set('n', 'gxf', function() get_location('$ccls/member', {kind=3}, lopts) end, opts)
vim.keymap.set('n', 'gxm', function() get_location('$ccls/member', {}, lopts) end, opts)
vim.keymap.set('n', '<C-j>', function() get_location('$ccls/navigate', {direction='D'}, lopts) end, opts)
vim.keymap.set('n', '<C-k>', function() get_location('$ccls/navigate', {direction='U'}, lopts) end, opts)
vim.keymap.set('n', '<C-h>', function() get_location('$ccls/navigate', {direction='L'}, lopts) end, opts)
vim.keymap.set('n', '<C-l>', function() get_location('$ccls/navigate', {direction='R'}, lopts) end, opts)
end,
