Hello I’m using this one (vscode-eex-format). But it requires to have ruby and its gem " htmlbeautifier" installed to work.

For the job it does I think it’s worth it.

This is good because it can be run from the command line and is editor-agnostic.

Unfortunately it requires installing ruby.

@Kurisu Do you have some way of using this in a CI pipeline? I would like to format html.eex file automatically in CI.

Writing this for posterity:

Currently I do it using the Ruby Gem htmlbeautifier (thanks @Kurisu) .

To setup:

Install ruby with:

$ asdf plugin-add ruby
$ asdf install ruby 3.0.0-dev
$ asdf global ruby 3.0.0-dev

Open a new shell and:

$ gem install html beautifier

Then to format at any time, do something like this:

$ find lib -name "*.html.*eex" | xargs ~/.asdf/installs/ruby/3.0.0-dev/bin/htmlbeautifier
