Whoot Whoot! We got a hashflag for our 20th Birthday! Create or edit wiki pages locally Wikis are based on Git repositories, so you can clone them locally and edit them like you would do with every other Git repository.
To clone a wiki repository locally, select Clone repository from the right-hand sidebar of any wiki page, and follow the on-screen instructions. Files you add to your wiki locally must use one of the following supported extensions, depending on the markup language you wish to use.
AsciiDoc extensions:. Other markup extensions:. Special characters in page titles Wiki pages are stored as files in a Git repository, so certain characters have a special meaning: Spaces are converted into hyphens when storing a page.
Hyphens - are converted back into spaces when displaying a page. Length restrictions for file and directory names Introduced in GitLab Many common file systems have a limit of bytes for file and directory names. Git and GitLab both support paths exceeding those limits. However, if your file system enforces these limits, you cannot check out a local copy of a wiki that contains filenames exceeding this limit. To prevent this problem, the GitLab web interface and API enforce these limits: bytes for page titles reserving 10 bytes for the file extension.
While you can still create files locally that exceed these limits, your teammates may not be able to check out the wiki locally afterward. Edit a wiki page You need at least the Developer role to edit a wiki page: On the top bar, select Menu. Go to the page you want to edit, and either: Use the e wiki keyboard shortcut. Select the edit icon. Edit the content. Select Save changes. For an example, read Table of contents.
Delete a wiki page You need at least the Developer role to delete a wiki page: On the top bar, select Menu. Go to the page you want to delete. Select Delete page. Confirm the deletion. Move a wiki page You need at least the Developer role to move a wiki page: On the top bar, select Menu.
Go to the page you want to move. Add the new path to the Title field. The page author. The commit message. The last update.
