Changes tab

The Changes tab is the pull request's diff, file by file, with the code highlighted and each review thread shown under the line it is about. A list of the changed files sits beside the diff. The number on the tab counts the changed files.

#What you see

• Changed files: the files as a tree, each with its thread states. Choose one to jump to it. Drag its edge to resize it.
• The diff, with added and removed lines. Lock files and large files (over about 400 changed lines) start folded; open one with its header.
• Markdown files rendered. A changed Markdown file (.md, .mdx, .markdown) shows as formatted text. Until you choose Show whole file, only the changed parts are shown. Review threads on a Markdown file are in its plain-text view.
• Threads on their lines. A thread whose code has moved since it was written is placed on the code it was written against, and says it may be a few lines off.

#What you can do

• Move around. n and p go to the next or previous file; ] and [ go to the next or previous review thread.
• Fold files. Collapse or expand one file, or use Expand all and Collapse all.
• See more of the file. Expand the gaps between changed parts to read the code around them.
• Switch a Markdown file's view. Plain text in the file's header shows its diff; Rendered goes back. Limn remembers your choice for every Markdown file.
• Wrap lines. Wrap lines wraps long lines instead of scrolling sideways.
• Comment on a line. Comment on this line starts a review comment on GitHub, under your account.
• Reply to and resolve threads in place, as on the Threads tab.
• Copy file path, or view this file on GitHub.

Very large pull requests

GitHub sends only part of a very large diff. Limn shows what it has and offers Load full diff. GitHub lists at most 3,000 files in a pull request. A file over 1 MB, or a binary file, is listed without a diff.
