# Script to check and minimize JavaScript for distribution.
#
# Requirements:
# - Requires Python/Closure Linter and Java/Closure Compiler, see
#   <http://code.google.com/closure>. Install this using npm.
#   Please see the Closure Linter documentation for installation instructions
#   of that tool.
#
# - Requires jslint4java, see <http://code.google.com/p/jslint4java/>. Expects the
#   jslint4java.jar (must be renamed!) in the same path as the Closure compiler,
#   i.e. in TOOL_PATH as configured below.
#
# - This tool expects to be run from the application's main directory.
#
# Usage: lib/pkp/tools/buildjs.sh [-n]
# ...where -n can be optionally specified to prevent caching.
#

### OS specific configuration ###

# Define a tab to be used inside of sed commands (sed on OSX does not recognize \t)
TAB=$'\t'

# Determine what flag to use for extended regular expressions
if [ `uname` == 'Darwin' ]; then
	EXTENDED_REGEX_FLAG='E'
else
	EXTENDED_REGEX_FLAG='r'
fi

### Configuration ###

TOOL_PATH=~/bin

### Command Line Options ###

OPTIND=1
DO_CACHE=1
while getopts "n" opt; do
	case "$opt" in
		n)	DO_CACHE=0 # No caching

		# - Do not alert on whitespace checking which we prefer to be checked by gjslint.
		#   This is necessary to remove inconsistency between gjslint's and
		#   jslint's whitespace rules.
		# - We allow dangling underscores (_) to mark private properties and let the
		#   Closure compiler enforce it.
		# - We allow the ++ and == syntax
		# - We allow "continue"
		# - Multiple var statements in one function are allowed to reduce variable span.
		# - We allow code without the 'use strict' pragma as we need the callee property
		#   for our class framework implementation.
