Version 0.17 released

For the fourth WP-CLI release of 2014, we have a number of enhancements that will make you go “oooh” and “ahhh”.

Speed!!!

Use wp search-replace while migrating large databases? You should submit a pull request to WP-CLI with your newly-found free time 🙂

Historically, this command performed the search and replace operation in PHP, as to not break arrays and objects serialized in the database.

Now, this command performs a check to see if there is any serialized data in the column it’s about to transform. If there isn’t, the command will perform a SQL search and replace. If there is serialized data, the command falls back to PHP search and replace.

One happy developer reported this new approach took 20 minutes on a large test database, compared to 8-12 hours previously — a 3,000% performance increase.

Manage languages

WordPress 4.0 lets a user pick a language on installation, or later through General Settings. WP-CLI now lets you see available languages, and install / activate one of your choosing.

$ wp core language list

Checking updates

v0.17.0 introduces two commands for checking for updates.

For WP-CLI:

$ wp cli version
WP-CLI 0.16.0
$ wp cli check-update
+---------+-------------+-------------------------------------------------------------------------------+
| version | update_type | package_url                                                                   |
+---------+-------------+-------------------------------------------------------------------------------+
| 0.17.0  | minor       | https://github.com/wp-cli/wp-cli/releases/download/v0.17.0/wp-cli.phar        |
+---------+-------------+-------------------------------------------------------------------------------+

Or for WordPress core:

$ wp core version
3.9.1
$ wp core check-update
+---------+-------------+-------------------------------------------+
| version | update_type | package_url                               |
+---------+-------------+-------------------------------------------+
| 4.0     | major       | https://wordpress.org/wordpress-4.0.zip   |
| 3.9.2   | minor       | https://wordpress.org/wordpress-3.9.2.zip |
+---------+-------------+-------------------------------------------+

php-cli-tools v0.10.0/1

In the recent past, we took over maintainership of php-cli-tools. WP-CLI makes use of many of its features, so we were honored to be considered when jlogsdon was looking for a new home for the project.

During the course of this release cycle, we released two new versions of php-cli-tools, v0.10.0 and v0.10.1. Together, the changeset includes:

  • cliprompt() includes an option to hide input (useful for passwords, etc.).
  • cliTable auto-wraps contents of a cell based on TTY width.
  • SHELL_PIPE environment variable can be defined for determining whether TTY is piped.
  • Fix: Add fallback for mb_strlen() when PHP mbstring extension isn’t enabled (bug introduced in v0.9.5)
  • Fix: cliColors::length() now returns correct lengths for colorized strings

Going forward, php-cli-tools’ release cycle will be tied to WP-CLI’s — and WP-CLI will run php-cli-tools dev-master to help test out new features.

Other changes

Additions:

  • Full compatibility with WordPress 4.0.
  • wp core update: Caches package locally, for improved performance when updating multiple sites on the same server.
  • wp import: Import a directory of WXR files.
  • wp scaffold package-tests: Use WP-CLI’s Behat framework to add functional tests to your own command. See wiki for implementation details.
  • wp search-replace: Supports --quiet flag for verbosity.
  • wp term list: List terms for multiple taxonomies.
  • wp user import-csv: Create users from a remote CSV (e.g. stored in Dropbox or Google Drive).
  • WP_CLI::launch_self(): Optionally return the execution output (e.g. STDOUT or STDERR). Introduces a new WP_CLIProcess class for executing system commands.
  • Uploads directory will be created when installing core, if it doesn’t exist.
  • If a parameter missing, the description for the parameter will be shown in the error message.
  • Greatly increased PHPdoc coverage for WP-CLI internals.

Fixes:

  • Persists db collation when using wp db reset.
  • Running wp search-replace will no longer clobber other WP installs in the same database.
  • Prevents loading a required file twice if both global config and project config files require it.
  • When creating a user, the generated password will display again.
  • Fix fatal error in wp scaffold _s.
  • The --post__in argument works again for wp export.
  • Themes and plugins can be listed with their update_version.
  • When running or deleting cron events, all matching events will be affected (instead of just the first).
  • GUIDs are escaped as URLs for wp export.
  • Thanks to improvements in php-cli-tools, long strings in tables will be wrapped, instead of breaking output. See in action with wp theme get twentyfourteen.
