1---@brief
2---
3--- https://github.com/MaskRay/ccls/wiki
4---
5--- ccls relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) specified
6--- as compile_commands.json or, for simpler projects, a .ccls.
7--- For details on how to automatically generate one using CMake look [here](https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html). Alternatively, you can use [Bear](https://github.com/rizsotto/Bear).
8---
9--- Customization options are passed to ccls at initialization time via init_options, a list of available options can be found [here](https://github.com/MaskRay/ccls/wiki/Customization#initialization-options). For example:
10---
11--- ```lua
12--- vim.lsp.config("ccls", {
13--- init_options = {
14--- compilationDatabaseDirectory = "build";
15--- index = {
16--- threads = 0;
17--- };
18--- clang = {
19--- excludeArgs = { "-frounding-math"} ;
20--- };
21--- }
22--- })
23--- ```
