A normaliser/beautifier for HTML that also understands embedded Ruby. Ideal for tidying up Rails templates.
- Normalises hard tabs to spaces (or vice versa)
- Removes trailing spaces
- Indents after opening HTML elements
- Outdents before closing elements
- Collapses multiple whitespace
- Indents after block-opening embedded Ruby (if, do etc.)
- Outdents before closing Ruby blocks
- Outdents elsif and then indents again
- Indents the left-hand margin of JavaScript and CSS blocks to match the indentation level of the code
To update files in-place:
$ htmlbeautifier file1.html.erb [file2.html.erb ...]
or to operate on standard input and output:
$ htmlbeautifier < untidy.html.erb > formatted.html.erb
require 'htmlbeautifier'
beautiful = HtmlBeautifier.beautify(untify_html_string)
You can also specify how to indent (the default is two spaces):
beautiful = HtmlBeautifier.beautify(untidy_html_string, indent: "\t")
This is a Ruby gem.
To install the command-line tool (you may need sudo
):
$ gem install htmlbeautifier
To use the gem with Bundler, add to your Gemfile
:
gem 'htmlbeautifier'
- Follow these guidelines when writing commit messages (briefly, the first line should begin with a capital letter, use the imperative mood, be no more than 50 characters, and not end with a period).
- Include tests.
