I'm trying to get prettier working in spacemacs.
I have (prettier-js :location (recipe :url "https://raw.githubusercontent.com/prettier/prettier/master/editors/emacs/prettier-js.el" :fetcher url))
which is somewhat working, but then in Messages I see
Contacting host: raw.githubusercontent.com:443
Wrote /Users/travis/.emacs.d/.cache/quelpa/build/prettier-js/prettier-js.el
File: /Users/travis/.emacs.d/.cache/quelpa/build/prettier-js/prettier-js.stamp
Error getting PACKAGE-DESC: (search-failed ;;; prettier-js.el ends here)
Cannot load prettier-js
I don't know enough emacs yet to know know what a PACKAGE-DESC does, or if I need it to get prettier to load.
I'm trying to do this in a private layer
The docs say:
Add this to your init
(require 'prettier-js)
(add-hook 'js-mode-hook
(lambda ()
(add-hook 'before-save-hook 'prettier-before-save)))
I think I should have something like:
(defun myJS/post-init-prettier-js ()
"Initialize prettier-js"
(use-package prettier-js)
:defer t
:init
(progn
(add-hook 'before-save-hook 'prettier-before-save)
)
)
in my layer
As of the commit 9d2a108 Spacemacs comes with a layer that adds support for Prettier. You can use it today if you're using the develop
branch of Spacemacs or if you're reading this in the future and are using version 0.300 or something more recent.
To use it simply add prettier
as a layer in the list of layers specified by dotspacemacs-configuration-layers
. Additionally you should enable Prettier as a formatter for the layers for the languages in which you want to use Prettier. How to do this is documented in the specific layers. For JavaScript you should add the following to your dotspacemacs/user-init
.
(setq javascript-fmt-tool 'prettier)
With the above configuration the JavaScript layer will user Prettier to format JavaScript files.
prettier-js包现在在melpa上安装它在你的spacemacs文件中添加更漂亮的js到dotspacemacs-additional-packages。
There are a few steps that we need to perform in order to activate prettier
in Spacemacs :
1. Install prettier
integration in Spacemacs:
<SPC> <SPC>
(press the spacebar key twice), this will trigger HELM allowing us to search for Emacs commands.
After pressing <SPC> <SPC>
, type package-install
in the HELM buffer and press <RET>
(the Return/Enter key).
A list of packages will appear inside the HELM Package Install buffer, type prettier-js
in it and press <RET>
.
2. Install prettier
in your system:
The integration doesn't do anything without prettier
itself.
Assuming you already have node
and npm
installed, go to your terminal and type: npm install -g prettier
and press enter.
3. (Optional) Setup automatic format on save:
Open your .spacemacs
config file by pressing <SPC> <f> <e> <d>
.
Find the dotspacemacs/user-config
section of it and type the following snippet inside of it:
(defun dotspacemacs/user-config () (add-hook 'js2-mode-hook 'prettier-js-mode) (add-hook 'web-mode-hook 'prettier-js-mode) )
Save the settings' change by pressing <SPC> <f> <s>
Reload the saved settings by pressing <SPC> <f> <e> <R>
