Clean, inspect and normalize patch text into a readable diff.
Paste or upload a .patch/.diff file and inspect its headers, hunks, changed lines and normalized unified representation.
A unified patch normally contains file headers followed by hunk headers such as @@ -old,count +new,count @@. Lines beginning with +, - and a space represent additions, removals and context.
Check that each hunk has a valid header, paths are sensible, context lines are preserved and additions/removals are balanced with the intended change.
Malformed hunk ranges, missing file headers and accidental pasted terminal output are common reasons a patch cannot be applied cleanly.
Paste or upload a .patch/.diff file and inspect its headers, hunks, changed lines and normalized unified representation.
Use the input area to paste text or upload an existing file, then process it and inspect the generated result, warnings and statistics.
Use the supplied sample first, then replace it with a real repository export, configuration file, branch list or measurement report appropriate to this tool.
