Enable issue linking for issue creation

[mimor]

We can link MR's to an issue, but we are not able to link related issues through the cli.

The current flow is:

• create an issue glab issue create --title "" --description ""
• go to the web-interface to link the relevant issue.

Possible solution:

Introduce a --linked-issue flag, that takes an issue ulr/id from the cli.

Thanks @mimor for your suggestion.
We are very careful implementing features that are limited by GitLab tiers and newer.

glab relies heavily on the GitLab API and it seems the Issues Link API falls into the two categories I have mentioned.

The simple “relates to” relationship moved to GitLab Core in 13.4.

We may however, consider this one since it is now supported for GitLab.com Free. My only concern is it being new for GitLab Core users.

While you wait as we work on this, you can easily implement this with the glab api command as it helps you interact with the GitLab API directly.

glab api /projects/<PROJECT_ID_OR_PATH>/issues/1/links -X POST -F target_project_id=<PROJECT_ID_OR_PATH> -F target_issue_iid=<TARGET_ISSUE_ID>

Here is an example:

glab api /projects/glab-cli%2Ftest/issues/1/links -X POST -F target_project_id=glab-cli/test -F target_issue_iid=2

You can set a short alias for this command with:

glab alias set linkIssue 'api /projects/$1/issues/$2/links -X POST -F target_project_id=$1 -F target_issue_iid=$3'

and now you should be able to use glab linkIssue command like:

glab linkIssue <PROJECT_ID_OR_PATH> <ISSUE_ID> <TARGET_ISSUE_ID>

Example:

glab linkIssue glab-cli%2Ftest 1 2

glab is highly customizable so you can use it whichever way you want it.

I'd like to complement you on this awesome and complete response 👏

@profclems Thank you for a great program!!

Slight correction to help others wanting to link issues.

This doesn't work for me:

glab alias set linkIssue 'api /projects/$1/issues/$2/links -X POST -F target_project_id=$1 -F target_issue_iid=$3'
glab linkIssue glab-cli%2Ftest 1 2

However, this does, because, in the uri path, you need %2F (url-encoded /) but in the target_project_id you need /:

glab alias set linkIssue 'api /projects/$1%2F$2/issues/$3/links -X POST -F target_project_id=$1/$2 -F target_issue_iid=$4'
glab linkIssue glab-cli test 1 2
