This PR adds the ability to copy the permalink to a line from within Zed. This functionality is available through the `editor: copy permalink to line` action in the command palette: <img width="589" alt="Screenshot 2024-01-30 at 7 07 46 PM" src="https://github.com/zed-industries/zed/assets/1486634/332282cb-211f-4f16-9eb1-415bcfee9b7b"> Executing this action will create a permalink to the currently selected line(s) and copy it to the clipboard. Here is an example line: ``` https://github.com/maxdeviant/auk/blob/56c80e80112744740be1969c89fdd34db4be6f64/src/lib.rs#L25 ``` Currently, both GitHub and GitLab are supported. ### Notes and known limitations - In order to determine where to permalink to, we read the URL of the `origin` remote in Git. This feature will not work if the `origin` remote is not present. - Attempting to permalink to a ref that is not pushed to the origin will result in the link 404ing. - Attempting to permalink when Git is in a dirty state may not generate the right link. - For instance, modifying a file (e.g., adding new lines) and grabbing a permalink to it will result in incorrect line numbers. Release Notes: - Added the ability to copy a permalink to a line ([#6777](https://github.com/zed-industries/zed/issues/6777)). - Available via the `editor: copy permalink to line` action in the command palette.
