How to set file labels in p4merge

Question

When p4merge is invoked from p4v it displays depot paths as labels on the files. I would like to use p4merge as a diff viewer for SVN, and to that end I have this batch file:

@echo off
pause
p4merge %6 %7

This works, but the labels appearing on the left and right panels are the names of the temporary files SVN has created to feed to p4merge. Arguments %3 and %5 that SVN passes to the batch file contain appropriate labels for the left and right panels respectively. I am sure I remember there being command-line arguments to set what labels you want to appear on each of the panels, but they are not listed by p4merge -h. What are they?

Answer 1

It looks like the options I was looking for are -nl NAME to name the left pane and -nr NAME to name the right pane. So my batch file is now:

@echo off
pause
p4merge -nl %3 -nr %5 %6 %7

Cheers for undocumented parameters. – Calculate

For those interested in renaming also the others panels for the merge: -nb sets the label for the base file panel; -nm sets the label for the merge file panel – Paleontography

Sorry to hijack your answer but for my own selfish gain I'm going to document my preferred TortoiseSVN Merge tool setting here so I'll find it again later. "C:\Program Files\Perforce\p4merge.exe" -nl "%tname (theirs)" -nr "%yname (mine)" -nb "%bname (base)" -nm "%mname (merged)" %base %theirs %mine %merged – Achromatic

Hey!! are there any undocumented parameters to change the font? – Tedium
