# This script builds and runs GM in current workspace with another Skia
|
||
|
|
# revision user specifies, and then compares their results. This script is
|
||
|
|
# useful when developers want to know whether their changes would cause any
|
||
|
|
# regression.
|
||
|
|
#
|
||
|
|
# As the name of this script tells, it only works for git repository. :)
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# Put this script into where your PATH can find it.
|
||
|
|
# And then invoke:
|
||
|
|
# $ git skia-verify [sha1-to-compare-default-is-HEAD^]
|
||
|
|
# It would delete {before,after,diff} directory under the current directory,
|
||
|
|
# so be warned!
|
||
|
|
# After it's done, check out diff/index.html for the possible differences.
