Woohoo!

Over the course of 5+ years, hundreds of contributors have worked to bring you WP-CLI v1.0.0, which I’m proud to announce today.

This release represents a level of maturity few open source projects achieve. It also marks a moment of transition. The WP-CLI project will shift its focus to the WP-CLI package ecosystem, where it will enable innovation by building and encouraging new features as standalone packages. We hope this approach will promote faster iteration and more creativity, and more sustainably distribute the maintenance burden. As these community packages find success, we’ll bring their learnings back into WP-CLI, alongside bug fixes and minor enhancements.

Now that the issue backlog is down to zero, I’m personally looking forward to getting more ideas cooking for runcommand, my own WP-CLI innovation studio.

Headed to Philly this week? I’ll be at Post Status Publish and WCUS (although only until mid-afternoon Friday). Say hello - I’m @danielbachhuber on Twitter.

On with the show…

Introducing WP_CLI::runcommand()

WP_CLI::runcommand() (doc) is the new best way to run WP-CLI commands from within your WP-CLI command. It’s as though WP_CLI::run_command() and WP_CLI::launch_self() grew up, married, and had the perfect child.

With WP_CLI::runcommand() , you can:

Launch a new child process (default), or reuse the existing process.

Optionally prevent the process from exiting on error.

Return STDOUT generated by the command, or all command execution details (STDOUT, STDERR, return_code) as an object.

Optionally parse captured STDOUT as JSON.

Relevant pull requests include: #3605, #3619, #3621.

Breaking change: Uses return code 1 when batch operation partially fails

Some commands support performing the same operation against multiple resources (e.g. updating two or more plugins with wp plugin update akismet hello ). Previously, if one of the operations failed (e.g. a plugin update failed to be downloaded), WP-CLI would display a warning, continue on, and exit with return code 0. Beginning in v1.0.0, WP-CLI uses return code 1 when one or more operations fails.

See this issue for more background and rationale.

Affected commands include:

wp media (regenerate|import)

wp menu delete

wp menu item delete

wp plugin (install|activate|update|toggle|deactivate|uninstall|delete)

wp super-admin add

wp theme (install|update)

wp term delete

wp widget (delete|deactivate|reset)

Use WP_CLI\Utils\report_batch_operation_results() (doc) in your custom WP-CLI commands to more easily support this behavior.

Relevant pull requests include: #3584, #3583, #3582, #3585, #3586, #3588.
