Helper script for Roots' Sage starter theme: make WPML's String Translation see WordPress's l10n gettext function in PHP Blade templates, like {{ __('Foo', 'domain') }}

gettexts-fake-update.sh

#!/bin/bash

# Scans blade templates for WordPress's gettext functions
# so WPML will pick them up for its String Translation.
# (WPML doesn't see something like {{ __('Hello World', 'sage') }}

# Put me into THEME/resources/assets/build 
# so $fn will point to THEME/resouces and WPML can see it
# (and it's out of sage's way)

fn="../../gettexts-fake.php"

# prevent execution; doesn't matter for WPML
echo "<?php die;" > $fn

#NOTE the regex expects somewhat wellformed gettexts with a \w+ domain
# like __('Hello', 'domain')
find ../../.. -name '*.blade.php' ! -path '*/vendor/*' \
        -exec grep -Po "\\b(__|_x|_e|_ex|_n|_nx|esc_html_[_ex]|esc_attr_[_ex])\\(.*?,\\s*[\"\']\w+[\"\']\\s*\\)" \{\} \; \
        | sed -e 's/$/;/' >> $fn

cat "$fn"

Thanks!
