Renaming a Plugin

Often you might decide the name you gave to the plugin is not as succinctly descriptive as you might like. The following commands rename a plugin:

Close your PhpStorm window first. Then enter the following commands in a Terminal window.

old_plugin_name="Example Plugin"
new_plugin_name="New Name For Example Plugin"

old_plugin_slug=$(echo $old_plugin_name | tr '[:upper:]' '[:lower:]' | sed 's/ /-/g');
old_plugin_snake=$(echo $old_plugin_name | tr '[:upper:]' '[:lower:]' | sed 's/ /_/g');
old_plugin_package_name=$(echo $old_plugin_name | sed 's/ /_/g');
old_plugin_capitalized=$(echo $old_plugin_name | tr '[:lower:]' '[:upper:]' | sed 's/ /_/g');
old_test_site_db_name=$old_plugin_snake"_tests"; # TODO: 64 character limit.
old_test_db_name=$old_plugin_snake"_integration"; # TODO: 64 character limit.
old_plugin_db_username=${old_plugin_slug:0:31};
old_plugin_db_password=$old_plugin_slug;

new_plugin_slug=$(echo $new_plugin_name | tr '[:upper:]' '[:lower:]' | sed 's/ /-/g');
new_plugin_snake=$(echo $new_plugin_name | tr '[:upper:]' '[:lower:]' | sed 's/ /_/g');
new_plugin_package_name=$(echo $new_plugin_name | sed 's/ /_/g');
new_plugin_capitalized=$(echo $new_plugin_name | tr '[:lower:]' '[:upper:]' | sed 's/ /_/g');
new_test_site_db_name=$new_plugin_snake"_tests";
new_test_db_name=$new_plugin_snake"_integration";
new_plugin_db_username=${new_plugin_slug:0:31};
new_plugin_db_password=$new_plugin_slug;

Delete all files that can be recreated

rm -rf wp-content;
rm -rf src/vendor;
rm -rf src/dependencies;
rm -rf vendor;
rm -rf wordpress;

rm -rf .idea;

Then the directory

cd ..; mv $old_plugin_slug $new_plugin_slug; cd $new_plugin_slug; 

Create the new database.

mysql_username="root";
mysql_password="secret";

export $(grep -v '^#' .env.testing | xargs);

# Create the databases.
mysql -u $mysql_username -p$mysql_password -e "CREATE USER '"$TEST_DB_USER"'@'%' IDENTIFIED WITH mysql_native_password BY '"$TEST_DB_PASSWORD"';";
mysql -u $mysql_username -p$mysql_password -e "CREATE DATABASE "$TEST_SITE_DB_NAME"; USE "$TEST_SITE_DB_NAME"; GRANT ALL PRIVILEGES ON "$TEST_SITE_DB_NAME".* TO '"$TEST_DB_USER"'@'%';";
mysql -u $mysql_username -p$mysql_password -e "CREATE DATABASE "$TEST_DB_NAME"; USE "$TEST_DB_NAME"; GRANT ALL PRIVILEGES ON "$TEST_DB_NAME".* TO '"$TEST_DB_USER"'@'%';";

Delete the old database

mysql_username="root";
mysql_password="secret";

mysql -u $mysql_username -p$mysql_password -e "DROP DATABASE IF EXISTS "$old_test_db_name";";
mysql -u $mysql_username -p$mysql_password -e "DROP DATABASE IF EXISTS "$old_test_site_db_name";";
mysql -u $mysql_username -p$mysql_password -e "DROP USER '"$old_plugin_db_username"';";

mysql -u $mysql_username -p$mysql_password $TEST_SITE_DB_NAME < tests/_data/dump.sql;

vendor/bin/wp option set home http://localhost:8080/$new_plugin_slug;
vendor/bin/wp option set siteurl http://localhost:8080/$new_plugin_slug;

mysqldump -u $TEST_SITE_DB_USER -p$TEST_SITE_DB_PASSWORD  $TEST_SITE_DB_NAME > tests/_data/dump.sql;

open -a PhpStorm ./;

composer install;

vendor/bin/codecept run acceptance;
