# preprocess.sh
|
|
#
|
|
# A simple code preprocessing wrapper that uses a combination of cpp, jssrip.py
|
|
# and sed to preprocess JavaScript files containing C-style preprocess macros
|
|
# (#include, #ifdef, etc.). Three options offer control over wether comments
|
|
# are preserved or stripped and whitespaces are compressed.
|
|
#
|
|
# Usage:
|
|
# preprocess.sh SOURCE DESTINATION ARGUMENTS MODE
|
|
#
|
|
# ARGUMENTS:
|
|
# e.g. "-DBROWSER"
|
|
#
|
|
# MODE:
|
|
# commented Preprocessed but still formated and commented (default)
|
|
# stripped Formated but without comments
|
|
# compressed No comments and no whitespaces
|
|
# compiled Uses Google Closure Compiler to reduce file size even more
