Example usage of triggers in https://github.com/HexRx/simple-ftp-deploy minifing javascript and css files on save

README.md

This is example usage of triggers in simple-ftp-deploy plugin for Sublime Text which automatically minifies javascript and css files using css-html-js-minify library, or alternativelly, using some CLI minifier, like minify.

Basically, minifier is called on save of any .css or .js file and .min.css or .min.js file is also automatically uploaded to server. And also, .min.css and .min.js file is deleted from server when you delete origin .css or .js file.

delete-minified.py

import os

# We get same variables as in minify.py

# Get filename without extension, so we can change the extension to .min.css / .min.js
filenameWithoutExtension, extension = os.path.splitext(filename)

# Continue only if not already minified
if not '.min' in filenameWithoutExtension:
  # send2trash is located in default package of Sublime Text
  import Default.send2trash as send2trash

  minFilename = filenameWithoutExtension + '.min' + extension

  # Send .min.css / .min.js file to trash (same as when we delete it from Sublime Text)
  send2trash.send2trash(minFilename)

  # And finally delete it from FTP server too
  ftp.delete(folder, minFilename)

minify.py

import subprocess, os, time

# When this trigger is executed, we get some variables, which are usefull for us, and they includes:
# folder -> absolute path to project root folder
# filename -> absolute path to file for which this trigger is processed
# __file__ -> absolute path to this file
# ftp -> ftp class from simple-ftp-deploy file (https://github.com/HexRx/simple-ftp-deploy/blob/master/main.py)
# config -> dictionary containing configuration from simple-ftp-deploy.json
# sublime -> see https://www.sublimetext.com/docs/api_reference.html#sublime

# and some function used by simple-ftp-deploy (also see https://github.com/HexRx/simple-ftp-deploy/blob/master/main.py for usage)

# msg -> function used by simple-ftp-deploy to display messages
# error -> function used by simple-ftp-deploy to display errors
# aks -> function used by simple-ftp-deploy to show ok/cancel dialog

# Get filename without extension, so we can change the extension to .min.css / .min.js
filenameWithoutExtension, extension = os.path.splitext(filename)

# Minify on if not already minified
if not '.min' in filenameWithoutExtension:
	
	minFilename = filenameWithoutExtension + '.min' + extension

	# Measure time to print statistics
	start = time.time()

	# Call css-html-js-minify/css-html-js-minify.py located in same folder as this file, with filename and wait for it to finish. New file should be generated with .min.js / .min.css extension
	subprocess.Popen([os.path.join(os.path.dirname(__file__), 'css-html-js-minify', 'css-html-js-minify.py'), filename], bufsize=-1, stderr=subprocess.STDOUT).wait()
	# Or alternativelly, use some CLI minifier, like https://github.com/tdewolff/minify/tree/master/cmd/minify
	# If you want to use other minifier, edit arguments below
	# subprocess.Popen(['minify', '-o', minFilename, filename], bufsize=-1, stderr=subprocess.STDOUT).wait()

	# Measure time to print statistics
	end = time.time()

	# Print message that we have minified that file (will print message in console and show in status bar)
	msg('[Minified {0}]: {1} to {2} ({3}ms)', filename.replace(folder, ''), minFilename.replace(folder, ''), str(round((end - start) * 1000)))

	# And finally upload our minified file
	ftp.upload(folder, minFilename)
