Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add html to the existing dotspacemacs-configuration-layers list in this file.

SCSS linting requires SCSS-Lint version >= 0.43.0. You can get it from GitHub:

  gem install specific_install
  gem specific_install https://github.com/brigade/scss-lint.git
  gem specific_install https://github.com/Sweetchuck/scss_lint_reporter_checkstyle.git

web-beautify

See web-beautify layer documentation.

prettier

See prettier layer documentation.

Choosing a formatter

To choose a formatter, set the layer variable web-fmt-tool:

  (html :variables web-fmt-tool 'web-beautify)

Formatter can be chosen on a per project basis using directory local variables (files named .dir-locals.el at the root of a project), an example to use the prettier formatter:

  ;;; Directory Local Variables
  ;;; For more information see (info "(emacs) Directory Variables")

  ((html-mode (web-fmt-tool . prettier)))

Note: you can easily add a directory local variable with SPC f v d.

Live display in browser

Use SPC m i to enable impatient mode, opening a live view of a HTML file in your browser. You may wish to enable impatient mode in referenced CSS or JS files, too.

When the underlying file is an HTML file, SPC m i automatically opens the page in the browser. For other buffers, a list of available views can be found on http://localhost:8080/imp.

For more information visit the help page on GitHub.
