Diffs.com says its new Edit mode is now live, built as a fresh editing implementation on top of the site's file and diff rendering primitives.
What’s new
- More than 189 commits went into the rewrite.
- The team added 900+ new tests.
- Edit mode lets any file or diff surface become editable in place, with switching between read-only review and live editing.
- It also supports selection actions, such as popping up context tools on selected text.
The post frames this as more than a Monaco or ProseMirror wrapper: it’s a purpose-built in-place editor for files and diffs.
