GitLab has automatic issue closing and issue closing patterns. Now it supports tasks in Issues and shows the amount of completed tasks in the Issue Board. However, it is still not possible to close tasks using the commit message.

Proposal

Closings tasks using the commit message.

Closing by number

Examples:

Closes #21(1) would close the 1st task of the Issue 21.

Closes #21(4) would close the 4th task of the Issue 21.

Closes #21(2, 5) would close the 2nd and the 5th tasks of the Issue 21.

Closes #21(1-3) would close from the 1st to the 3rd tasks of the Issue 21.

Closes #21(1-3, 5, 7, 9-11) would close the tasks 1, 2, 3, 5, 7, 9, 10, and 11 of the Issue 21.

Closing by description

Examples:

Closes #21[Show an animation while waiting the server to return] would close the task Show an animation while waiting the server to return of the Issue 21

Closes #21[Add a "Forgot Password" button] would close the task Add a "Forgot Password" button of the Issue 21

Expected outcomes

Developers will be able to close tasks automatically during commits, reducing the manual labor..
