This action analyses the titles of Pull Requests to ensure they start with a Jira Issue Key. Issue Keys are a combination of a Project Key, a hyphen, and a number designating which issue it is. In general, Project Keys are two capital letters but Jira does allow for custom Project Keys and this issue attempts to abide by the custom format.

For example, if your project key were AB then the following would be allowed

AB-1 Initialize Project

However, the following examples would not be allowed

aB-1 Initialize Project

ab-1 Initialize Project

Ab 1 Initialize Project

Valid Pull Request titles must also include a short description after the Issue Key. Therefore the following is not valid.

AB-1

Specifying a separator allows for using characters such as :, - or _ to be between the Jira key and title. As an example with the separator : the following is allowed

AB-1:Initialize Project

Note that by specifying a separator the following would not be allowed

AB-1: Initialize Project

By default this action checks that the Jira Project Key is at the start of the title string. To allow for the Jira Project Key to be anywhere in the title set the keyAnywhereInTitle property to true. With this property enabled and the project key set to AB the following title is valid

Other: AB-1 Initialize Project

By default, this action will allow any valid Issue Key so long as it could be valid. If you want to be specific to your project, use the projectKey input for the action.

A specific Project Key to always check for

A specific separator to use. Defaults to a space character.
