CSS-HTML-JS-Minify. StandAlone Async cross-platform Unicode-ready Python3-ready Minifier for the Web.

positional arguments:
  fullpath         Full path to local file or folder.

optional arguments:
  -h, --help       show this help message and exit
  --version        show programs version number and exit
  --wrap           Wrap output to ~80 chars per line, CSS only.
  --prefix PREFIX  Prefix string to prepend on output filenames.
  --timestamp      Add a Time Stamp on all CSS/JS output files.
  --quiet          Quiet, Silent, force disable all logging.
  --hash           Add SHA1 HEX-Digest 11chars Hash to Filenames.
  --zipy           GZIP Minified files as '*.gz', CSS/JS only.
  --sort           Alphabetically Sort CSS Properties, CSS only.
  --comments       Keep comments, CSS/HTML only (Not Recommended)
  --overwrite      Force overwrite all in-place (Not Recommended)
  --after AFTER    Command to execute after run (Experimental).
  --before BEFORE  Command to execute before run (Experimental).
  --watch          Re-Compress if file changes (Experimental).
  --multiple       Allow Multiple instances (Not Recommended).

CSS-HTML-JS-Minify: Takes a file or folder full path string and process all
CSS/HTML/JS found. If argument is not file/folder will fail. Check Updates
works on Python3. Std-In to Std-Out is deprecated since it may fail with
unicode characters. SHA1 HEX-Digest 11 Chars Hash on Filenames is used for
Server Cache. CSS Properties are Alpha-Sorted, to help spot cloned ones,
Selectors not. Watch works for whole folders, with minimum of ~60 Secs between
runs.
  • Takes a full path to anything, a file or a folder, then parse, optimize and compress for Production.
  • If full path is a folder with multiple files it will use Async Multiprocessing.
  • Pretty-Printed colored Logging to Standard Output and Log File on OS Temporary Folder.
  • Set its own Process name and show up on Process lists.
  • Can check for updates for itself.
  • Full Unicode/UTF-8 support.
  • Smooth CPU usage, Single Instance Checking.
  • Can Obfuscate, GZIP and Hash files, also Watch for changes on files.
  • Can execute arbitrary commands after and before running.
  • *.css files are saved as *.min.css, *.js are saved as *.min.js, *.htm are saved as *.html

Command-line usage

css-html-js-minify.py file.htm

css-html-js-minify.py file.css

css-html-js-minify.py file.js

css-html-js-minify.py /project/static/

Python code usage

from css_html_js_minify import process_single_html_file, process_single_js_file, process_single_css_file, html_minify, js_minify, css_minify

process_single_html_file('test.htm', overwrite=False)
# 'test.html'
process_single_js_file('test.js', overwrite=False)
# 'test.min.js'
process_single_css_file('test.css', overwrite=False)
# 'test.min.css'

html_minify('  <p>yolo<a  href="/" >o </a >     <!-- hello --></p>')
# '<p>yolo<a href="/" >o </a > </p>'
js_minify('var i = 1; i += 2 ;\n alert( "hello  "  ); //hi')
# 'var i=1;i+=2;alert("hello  ");'
css_minify('body {width: 50px;}\np {margin-top: 1em;/* hi */  }', comments=False)
# '@charset utf-8;body{width:50px}p{margin-top:1em}'

The optional arguments that these functions take are almost the same as the command-line flags. Check the list above (just use add_hash instead of hash). Additionally, you can force a specific path for the output files using output_path.

Install

pip install css-html-js-minify

Uninstall pip uninstall css-html-js-minify

Why?

  • Why another Compressor ?, there are lots of compressors for web files out there!; Or maybe not ?.
  • Many of them only work inside Django/Flask, or frameworks of PHP/Java/Ruby, or can not process whole folders.
  • This project is the big brother of another project that does the inverse, a Beautifier for the Web.

Migration

To keep things simple KISS, the human readable indented commented hackable HTML is kept as *.htm and the compressed production-ready as *.html. This is inspired from JavaScript/CSS *.min.js and *.min.css. We did not "invent" this file extension.

To migrate from typical file extension HTML to HTM, which is the exactly same, you can run this:

find . -name "*.html" -exec rename "s/.html/.htm/" "{}" \;

This will make a copy of all *.html renaming them as *.htm recursively from the current folder. Nothing deleted.

Requisites

Coding Style Guide

  • Lint, PEP-8, PEP-257, iSort must Pass Ok. pip install pep8 isort
  • If there are any kind of tests, they must pass. No tests is also acceptable, but having tests is better.

JavaScript support

  • ES6 and ES7 and future standards may not be fully supported since they change quickly, mainly driven by Node.JS releases.
  • Future JavaScript support is orphan, if you want to make ES6, ES7 work feel free to send pull request, we will merge it.
