WP-CLI v2.1.0 Release Notes

‘Tis the season to celebrate a new release of WP-CLI! 🎄 A total of 39 contributors has collaborated on this release to have a staggering 293 pull requests merged. We’ll go over the main areas now, but you also skip directly to the detailed changelog or ponder over the breaking changes section if you’re impatient.

i18n – round two!

The recent i18n make-pot command has replace the old make-pot tool in WordPress Core and is now the official translation build tool for the Core. This effort has lead to numerous improvements to make it both more robust and more flexible. Amongst the more notable changes, it can now parse JavaScript in addition to the PHP files, and together with the new i18n make-json command that lets you produce separate JSON files, you’re all set to make your Gutenberg blocks translatable!

Translation pack improvements

We didn’t stop there with regards to making WordPress an “international success”… the language family of commands got several improvements and fixes. The most notable one is that language plugin|theme update now understands an --all flag, so you can update language packs for all your installed plugins/themes in one go.
# Update the language packs for all plugins.
$ wp language plugin update --all
Updating 'Japanese' translation for Akismet 3.1.11...
Downloading translation from https://downloads.wordpress.org/translation/plugin/akismet/3.1.11/ja.zip...
Translation updated successfully.
Updating 'Japanese' translation for Contact Forms 7 4.2.1...
https://downloads.wordpress.org/translation/plugin/contact-form-7/4.2.1/ja.zip...
Translation updated successfully.
Success: Updated 2/2 translation.

Partial prompting

The lesser known --prompt global parameter has now become even more useful. Instead of always prompting for all arguments, it skips those that were already provided, as you would probably already have expected. One way this can be used is to prefill all arguments that you can remember and then use --prompt to help you with the more arcane flags. More importantly, though, you can now prefill all the arguments that are already known inside of a script, and then add the --prompt argument to let the script query the remaining information from the user.

Manage the WP-CLI cache

We added two additional commands that let you manage the WP-CLI internal cache. cli cache clear will clear the entire cache, whereas cli cache prune will only clear the elements known to be stale. This latter will for example remove all the versions of WP core that you downloaded except for the most recent one.
# Remove all cached files.
$ wp cli cache clear
Success: Cache cleared.

# Remove all cached files except for the newest version of each one.
$ wp cli cache prune
Success: Cache pruned.

Better control over transients

You can now list the current transients on your site or network using the filterable transient list command. You can search for specific transients or exclude the ones you want to hide. You can even choose whether you want the expiration to be displayed in a human-readable or machine-parseable format.
# List all transients
$ wp transient list
+------+-------+---------------+
| name | value | expiration    |
+------+-------+---------------+
| foo  | bar   | 39 mins       |
| foo2 | bar2  | no expiration |
| foo3 | bar2  | expired       |
| foo4 | bar4  | 4 hours       |
+------+-------+---------------+
Furthermore, transients are now handled more consistently across multisite networks, and allow you to properly distinguish between regular transients and site transients.

Database management improvements

Also, the db size loved the idea of a --human-readable flag like in the transient list command so much that it got its own version. This will always use the unit that is best adapted to convey the information.
# List the size of the database in a human-readable form
$ wp db size --tables --human-readable
+---------+--------+
| Name    | Size   |
+---------+--------+
| my_site | 117 MB |
+---------+--------+
Furthermore, the db import command now understands all the flags that the mysql binary does, so that you can get past errors in SQL exports or adapt the result you want to see in your target site.
# Import an SQL export file that contains errors, by
# passing the --force argument to mysql binary.
$ wp db import export-with-errors.sql --force
Success: Imported from 'export-with-errors.sql'.

Smarter configuration

The config commands are now smarter. They not only allow you to edit the wp-config.php even on a broken WordPress installation, but you’re also able to retrieve the individual settings in whatever format best fits your scripting needs. Finally, adding new configuration values or updating existing ones will now only throw errors in the most ambiguous scenarios, while they just work for the majority use cases without the need to explicitly specify a --type.

Checking the existence of a post

You can now check whether a given post exists by using the new post exists command. It returns a shell exit code, so you can use it directly in shell conditionals.
if wp post exists 42; then
   echo "Skipping post import for ID 42, it already exists."
else
   echo "Importing post with ID 42..."
   # ...
fi

Breaking changes

  • While we had already bumped the minimum PHP version in v2.0.0 and started using PHP 5.4+ code in some places, we now actively enforce this requirement in the bootstrapping code [wp-cli#5039](https://github.com/wp-cli/wp-cli/pull/5039).
  • The restructuring of the packages in v2.0.0 produced a regression which caused overrides through the package manager to not work anymore. We fixed this by completely ripping the framework out of the regular Composer autoload flow. This should now lead to less surprises when rearranging the Composer compositions, but might have side-effects in some exotic Composer setups [wp-cli#5010](https://github.com/wp-cli/wp-cli/pull/5010).
  • The breaking change from v2.0.1 to throw an error for non-lowercase theme slugs was reverted, as it broke far more than we anticipated. That’s why we now break the breaking change to get back to the original behavior [extension-command#137](https://github.com/wp-cli/extension-command/pull/137). 😛
  • WP-CLI tries to speak proper English now. To achieve this, we changed the output to use the real world “installation” where we were using the fantasy term “install” before [wp-cli#4946](https://github.com/wp-cli/wp-cli/pull/4946).
