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


- 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

```bash file.htm file.css file.js /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

- [Python 3.6+]( "Python Homepage")

# 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.
