# build.sh -- builds JAR and XPI files for mozilla extensions
#   by Nickolay Ponomarev <asqueella@gmail.com>
#   (original version based on Nathan Yergler's build script)
# Most recent version is at <http://kb.mozillazine.org/Bash_build_script>

# This script assumes the following directory structure:
# ./
#   chrome.manifest (optional - for newer extensions)
#   install.rdf
#   (other files listed in $ROOT_FILES)
#
#   content/    |
#   locale/     |} these can be named arbitrary and listed in $CHROME_PROVIDERS
#   skin/       |
#
#   defaults/   |
#   components/ |} these must be listed in $ROOT_DIRS in order to be packaged
#   ...         |
#
# It uses a temporary directory ./build when building; don't use that!
# Script's output is:
# ./$APP_NAME.xpi
# ./$APP_NAME.jar  (only if $KEEP_JAR=1)
# ./files -- the list of packaged files
#
# Note: It modifies chrome.manifest when packaging so that it points to 
#       chrome/$APP_NAME.jar!/*

#
# default configuration file is ./config_build.sh, unless another file is 
# specified in command-line. Available config variables:
APP_NAME=          # short-name, jar and xpi files name. Must be lowercase with no spaces
CHROME_PROVIDERS=  # which chrome providers we have (space-separated list)
CLEAN_UP=          # delete the jar / "files" when done?       (1/0)
ROOT_FILES=        # put these files in root of xpi (space separated list of leaf filenames)
ROOT_DIRS=         # ...and these directories       (space separated list)
BEFORE_BUILD=      # run this before building       (bash command)
AFTER_BUILD=       # ...and this after the build    (bash command)
