rmtabs

#!/bin/bash
# Normalize indentation tabs -> 2 spaces in distributed source.
#
# By default this covers .php, .css, and .js (unchanged behavior). A project
# can exclude one or more extensions by defining WP_SCRIPT_RMTABS_EXCLUDE_EXTS
# (comma-separated) in script/wp-script-config.php, e.g.:
#
#   define('WP_SCRIPT_RMTABS_EXCLUDE_EXTS', 'js');
#
# Use this when a project's JS/CSS indentation is owned by Prettier/ESLint and
# follows the WordPress tabs standard (e.g. Pretty Links) — tab stripping here
# would fight the linter and break its CI gate. When the constant is
# missing/empty (or the config file is absent), every extension is processed,
# so existing projects are unaffected.
