This change also removes parts of the existing docs that explain how to create a .clangd file with the project-recommended defaults. (Those docs are no longer necessary — since this change adds a .clangd file to the repo, containing those same defaults).

# Emacs Project Configuration
|
|
|
|
Emacs can be configured with `lsp-mode` and `clangd` to work well.
|
|
|
|
### clangd
|
|
|
|
The official clangd extension can be used for C++ comprehension.
|
|
|
|
Run cmake (`Meta/ladybird.sh run ladybird` or similar) at least once for clangd
|
|
to work, as doing so will generate the `Build/ladybird/compile_commands.json`
|
|
that is needed by `clangd`.
|
|
|
|
### lsp-mode
|
|
|
|
```lisp
|
|
(use-package lsp-mode
|
|
:hook ((c++-mode) . lsp-deferred)
|
|
:commands lsp
|
|
:config
|
|
(setq lsp-clients-clangd-args '("-j=4" "-background-index" "--log=error" "--clang-tidy" "--enable-config"))
|
|
;; Optionally, set the location of clangd -- See notes below for options.
|
|
(setq lsp-clangd-binary-path "/usr/bin/clangd"))
|
|
|
|
```
|
|
|
|
### clangd
|
|
|
|
There are a few different ways to specify which clangd to use:
|
|
|
|
- By default, without configuration `lsp-mode` will try to find and use your system `clangd`. This is the easiest solution, but your system clangd might be out of date.
|
|
- You can manually specify any `clangd` binary with `lsp-clangd-binary-path`, as shown in the use-package example above.
|
|
- You can have `lsp-mode` manage your `clangd` installation with emacs' `lsp-install-server`. This will install a `clangd` binary for you.
|
|
- You can build the LLVM toolchain, including `clangd`, from Ladybird's repository. This is an advanced option that is not currently documented.
|
|
|
|
### clang-format
|
|
|
|
There are multiple packages to handle auto formatting with
|
|
`clang-format`, within emacs. Choose what works best for your setup:
|
|
|
|
- [format-all-mode](https://github.com/lassik/emacs-format-all-the-code)
|
|
- [clang-format-plus](https://github.com/SavchenkoValeriy/emacs-clang-format-plus)
|
|
|
|
Alternatively, this can be done without additional packages, using `lsp-mode`.
|
|
You can use the following `.dir-locals.el` file placed in the project root:
|
|
|
|
```lisp
|
|
((c++-mode
|
|
(eval add-hook 'before-save-hook #'lsp-format-buffer nil t)))
|
|
```
