How to ignore bracketing styles when doing code comparisons or diffs? We have several formats of bracketing and I would like:

function foo(){
}

to be considered the same as

function foo()
{
}

Right now I use Araxis merge which does a direct line-by-line comparison and we are getting a lot of "false positive" changes.

    Run your code through a formatter before diffing it, that way you can use existing high quality diff tools. – whatsisname Mar 26 '14 at 18:51

    some diff tools let you ignore whitespace entirely – ratchet freak Mar 26 '14 at 19:02

    You've got 3 options on how you want to take this. If you want to ask about how to make Araxis merge handle this, SO may be a better target (specific tool use). If you are asking about workflows and team style guides, then P.SE (though I suspect there's a dup for it that you should read first). If you are looking for a new tool, then Software Recommendations.SE may be appropriate - given enough information about your features and environment. – user40980 Mar 26 '14 at 20:22

A tool like Semantic Merge which understands the language semantics by parsing the code will work in this case.

  • Could someone please explain the downvotes? I've never used Semantic Merge and at first glance it looks like a good suggestion. – M. Dudley Mar 27 '14 at 12:23
