Feature: Set the value of a constant or variable defined in wp-config.php file

  Background:
    Given a WP install

  Scenario: Update the value of an existing wp-config.php constant
    When I run `wp config set DB_HOST db.example.com`
    Then STDOUT should be:
      """
      Success: Updated the constant 'DB_HOST' in the 'wp-config.php' file with the value 'db.example.com'.
      """

    When I run `wp config get DB_HOST`
    Then STDOUT should be:
      """
      db.example.com
      """

  Scenario: Add a new value to wp-config.php
    When I run `wp config set NEW_CONSTANT constant_value --type=constant`
    Then STDOUT should be:
      """
      Success: Added the constant 'NEW_CONSTANT' to the 'wp-config.php' file with the value 'constant_value'.
      """

    When I run `wp config get NEW_CONSTANT`
    Then STDOUT should be:
      """
      constant_value

    When I run `wp config set new_variable variable_value --type=variable`
    Then STDOUT should be:

      Success: Added the variable 'new_variable' to the 'wp-config.php' file with the value 'variable_value'.
      """

    When I run `wp config get new_variable`
    Then STDOUT should be:
      """
      variable_value
      """

    When I try `wp config set SOME_NAME some_value`
    Then STDERR should be:
      """
      Error: The constant or variable 'SOME_NAME' is not defined in the 'wp-config.php' file. Specify an explicit --type=<type> to add.

    When I try `wp config get SOME_NAME`
    Then STDERR should be:
      """
      Error: The constant or variable 'SOME_NAME' is not defined in the 'wp-config.php' file.

  Scenario: Updating a non-existent value without --add
    When I try `wp config set NEW_CONSTANT constant_value --no-add`
    Then STDERR should be:

    When I try `wp config set table_prefix new_prefix --type=constant --no-add`
    Then STDERR should be:
      """
      Error: The constant 'table_prefix' is not defined in the 'wp-config.php' file.

    When I run `wp config set table_prefix new_prefix --type=variable --no-add`
    Then STDOUT should be:

  Scenario: Update raw values
    When I run `wp config set WP_DEBUG true --type=constant`
    Then STDOUT should be:
      """
      Success: Added the constant 'WP_DEBUG' to the 'wp-config.php' file with the value 'true'.

    When I run `wp config list WP_DEBUG --strict --format=json`

  Scenario: Ambiguous change requests throw errors

      Error: Found both a constant and a variable 'SOME_NAME' in the 'wp-config.php' file. Use --type=<type> to disambiguate.

  Scenario: Additions can be properly placed
    Given a wp-config.php file:
