# Usage: local_build.sh.
|
|
#
|
|
# This script generates only local_blockly_compressed.js. You may modify it as
|
|
# needed to build other files.
|
|
#
|
|
# The compressed file is a concatenation of all of Blockly's core files, run
|
|
# through a local copy of Google's Closure Compiler with simple optimizations
|
|
# turned on.
|
|
|
|
# Future work:
|
|
# - Trim down Google's Apache licenses, to match the output of build.py.
|
|
# - Generate other compressed files generated by build.py normally.
|
|
# - Add a good error message if multiple versions of the closure compiler were
|
|
# found.
|
|
|
|
# Find the Closure Compiler.
