Question 1

How do I use htmlbeautifier in a Rails project?

Accepted Answer

Install the gem via Bundler by adding 'gem "htmlbeautifier"' to your Gemfile, then run it from the command line on ERB files or integrate it into Rake tasks for automated formatting.

Question 2

Htmlbeautifier vs Prettier for HTML formatting?

Accepted Answer

Htmlbeautifier specializes in embedded Ruby (ERB) and is Ruby-based, while Prettier is a multi-language formatter with broader support but less focus on Ruby blocks. Choose htmlbeautifier for Rails templates and Prettier for general web projects.

Question 3

Can htmlbeautifier format JavaScript inside HTML?

Accepted Answer

Yes, it indents JavaScript and CSS blocks to match the surrounding code's indentation level, as mentioned in the README, but it doesn't fully parse or beautify the JavaScript syntax itself.

Question 4

How to set up htmlbeautifier as a pre-commit hook?

Accepted Answer

Use tools like Overcommit or a simple Git hook script that runs 'htmlbeautifier' on staged ERB files before commits, ensuring formatted code is checked in.

Question 5

Does htmlbeautifier work with HAML or Slim templates?

Accepted Answer

No, it's designed for HTML with embedded Ruby (ERB), so it won't correctly format HAML or Slim files, which have different syntax and require dedicated formatters.

Question 6

How to customize indentation size in htmlbeautifier?

Accepted Answer

Pass the 'indent' parameter in code, e.g., 'HtmlBeautifier.beautify(html, indent: "  ")' for two spaces, or use command-line options by modifying the source if not directly supported.
