If you are only able to bring up a two-window merge, you most likely have the "Standard" version and you will need to upgrade in order to have a three-way merge. Important Note: Araxis Merge Professional is needed if you require three-way merging. AraxisMerge is a popular merge tool for Windows and Mac OS X platforms available from Araxis Ltd. The general form of a Windows-style batch file is:::merge.bat::merge.exe %1 %2 %3 %4ĪraxisMerge serves as a good case study of the generic process of integrating third-party merge tools. If you need to specify command line options to the diff/merge program, then you can wrap these in a batch file and provide the batch file name to P4MERGE. Perforce, the company best known for its enterprise version control platform, also offers a solid diff tool: P4Merge is free of charge and comes with a basic feature set that makes it an interesting option on Windows, macOS and Linux.

To specify a third-party diff/merge, set the P4MERGE environment variable. DeltaWalker supports Windows, macOS and Linux. (Here, the "xxx" and (n) would be replaced by a unique file number sequence.) These four files can then be used as input to a third-party diff/merge program during the resolve process.įor example, if you were integrating into a file named "foo.c", Perforce passes the following arguments to an external merge program.txxxt(n).tmp = base read-only temp filetxxxt(n+1).tmp = theirs read-only temp filefoo.c = yours local copy of target file open for integratetxxxt(n+2).tmp = merge writable temp file the target file (also known as "yours").the source file (also known as "theirs").The four files, in order of presentation, are: When resolving files and selecting the merge option, Perforce outputs four files. Using Third-Party Merge Tools with the Command-Line P4 In the arguments example above, %b is the base, %1 is the source, %2 is the target, and %r is the result file. An xterm can be used to run shell script merges if desired. Note that this tool should be a graphical utility that opens its own windows even on platforms such as Linux.

You can configure this by choosing P4V - > Preferences -> Tools, then clicking the Merge tab, clicking the radio button Use external application, and entering the filename there. Perforce's cross-platform GUI contains not only its own powerful merging capabilities, but also the built-in ability to use an external merge program.
