Help: /fdiff
Bounty program for improvements to Tcl and certain Tcl packages.

The "/fdiff" page:

URL: fdiff?v1=HASH&v2=HASH

Two arguments, v1 and v2, identify the artifacts to be diffed. Show diff side by side unless sbs is 0. Generate plain text if "patch" is present, otherwise generate "pretty" HTML.

Alternative URL: fdiff?from=filename1&to=filename2&ci=checkin

If the "from" and "to" query parameters are both present, then they are the names of two files within the check-in "ci" that are diffed. If the "ci" parameter is omitted, then the most recent check-in ("tip") is used.

Additional parameters:

Show N lines of context around each diff
Use the patch diff format
Only show differences that match REGEX
Turn side-by-side diffs on and off (default: on)
Show more detail when describing artifacts
Ignore whitespace
