# WriteFreely CSS invalidation script |
|
|
|
# |
|
|
|
# usage: ./invalidate-css.sh <build-directory> |
|
|
|
# |
|
|
|
# This script provides an automated way to invalidate stylesheets cached in the |
|
|
|
# browser. It uses the last git commit hashes of the most frequently modified |
|
|
|
# LESS files in the project and appends them to the stylesheet `href` in all |
|
|
|
# template files. |
|
|
|
# |
|
|
|
# This is designed to be used when building a WriteFreely release. |
