Hi there and thanks for your contribution! Can you please share some additional context on this particular PR?

At first glance I don't think it makes sense to support this as-is.

Usually, if you want to use a custom default value for an argument like that, the way to do itis via a wp-cli.yml config file. See https://make.wordpress.org/cli/handbook/references/config/ for an example of how to set default values.

If that doesn't solve your use case, for example if you'd like the config file to read from an environment variable or something, I'd suggest first opening an issue outlining your problem, what you have tried so far, and a possible solution.

Hey, the context is actually inside the commit itself: a8308bb

P.S. created an issue #262.

@ton31337 You can achieve a similar result with the --prompt= argument.

Including --prompt=admin_password will cause WP-CLI to prompt just for the --admin_password= argument:

$ wp core install --url=vanilla.test --title=vanilla --admin_user=daniel --admin_email=daniel@bachhuber.co --prompt=admin_password
2/4 [--admin_password=<password>]:

You can then pipe the value to the command:

$ echo 'foobar' | wp core install --url=vanilla.test --title=vanilla --admin_user=daniel --admin_email=daniel@bachhuber.co --prompt=admin_password
wp core install --title='vanilla' --admin_user='daniel' --admin_email='daniel@bachhuber.co' --admin_password='foobar'
Success: WordPress installed successfully.

Would this serve your needs?

@danielbachhuber thanks for the response, but my case is a bit different. STDIN, neither file works for me, because with STDIN the password is visible in the process list (e.g. ps aufx). That's why I need this information to be parsed directly in PHP, and not by the arguments. I hope this gives you a better view of the issue :)

@ton31337 I'd rather not scatter more environment variables throughout the codebase if possible. Are there any other implementations you can think of?

Nope, this is the most proper way achieving what's desired. If you have any other idea, let me know.

@ton31337 This is just one of many places where directly passing sensitive information can be leaked into the process list or similar, so adding environment variables for these is not really scalable.

As @danielbachhuber mentioned, WP-CLI supports file-based approaches to solve this in a more generic way:

1. You can put the sensitive information into a configuration file. The file would be a YAML file with the following structure:

   core install:
       admin_password: 123456

   You can then point your WP-CLI execution to a custom location for that file if you generate it dynamically:

   WP_CLI_CONFIG_PATH=/path/to/custom/wp-cli.yml wp core install

2. You can let WP-CLI require an additional PHP file that gets executed from within the context of WP-CLI. This way, you have full control of the entire execution. You can for example hook into the random_password filter to control what the generated password will be:

   <?php
   // Hook into the WP-CLI process to act when the `wp core install` command is being triggered.
   WP_CLI::add_hook( 'before_invoke:core install', function() {
   
       // Compute the admin password in whatever way you want.
       // This can come from a file, be queried via an API, etc...
       $admin_password = '123456';
   
       // Hook into the `random_password` filter to return the computed password.
       WP_CLI::add_wp_hook( 'random_password', function() use ( $admin_password ) {
           return $admin_password;
       } );
   } );

   This can be used via the --require=<path-to-script.php> flag:

   wp core install --require=<path/to/script.php>

3. You can combine approaches and have a custom config (from wherever it comes) to add the --require=<path-to-script.php> to the WP-CLI binary.
   The config file would then look like this:

   require:
       - path/to/script.php
