Create GFM reference for file + line number in the Web IDE
Problem to Solve
In #21762 (closed) we'll introduce the ability to link to specific line numbers of a file in the Web IDE. Providing full links is distracting and takes up lots of space when referencing them in comments or other places that support GitLab Flavored Markdown.
Additional Details
Currently this is not supported by linking to a specific file in the repository browser either:
We should continue to evaluate demand for this feature as link sharing directly to the Web IDE increases.
Proposal
We should create a specific link syntax for quickly and easily sharing links directly to a file + line number in the Web IDE.
