How do I make Beyond Compare ignore certain differences while comparing versions of Delphi Form Files

StackOverflow https://stackoverflow.com/questions/3668439

Question

I use Beyond Compare (version 3.1.10) to compare different versions of Delphi Form Files, but I don't want to see differences concerning ExplicitTop, ExplicitLeft, ExplicitHeight and ExplicitWidth.

Details: These lines will always begin with a number of whitespace characters, then "ExplicitXXX = " and a number. Older versions of Delphi didn't have these lines, so I want to ignore differences where these lines are added to the newest version, and I also want to ignore differences where the number has changed.

Does anyone know how to do this?

Was it helpful?

Solution

  1. Load a pair of DFM files showing the difference.
  2. Click the Session Settings button (aka Rules w/ umpire icon) or use the Session->Session Settings menu item.
  3. Switch to the Importance tab then click the Edit Grammar... button to open a second dialog.
  4. Click the New... button below the top listbox to open a third dialog.
  5. Change the Element Name option to something like Explicit*, change the Text Matching to Explicit(Left|Top|Width|Height) = \d+ and check the Match character case and Regular expression checkboxes, then click Ok, then click Ok again in the second dialog.
  6. Explicit* should now appear in the original dialog's Grammar Elements list. Uncheck it, then change the combobox at the bottom of the dialog from Use for this view only to Update session defaults.

OTHER TIPS

I don't use Beyond Compare, but if you want to have newer versions of Delphi stop adding the (IMO useless) Explicit* properties, you can use Andreas Hausladen's DDevExtensions

In my case (C#), I wanted to ignore the entire line which contained namespaces (and thus, using's) which I changed. (Referenced Walkthrough - Ignore entire line if text exist in line

ie. 

namespace INSERT.NAMESPACE.HERE 
      changed to 
namespace INSERT.NAMESPACE.HERE.NEW

To do that

In step 5. of Craig's solution, change the Text Matching to 

" .\*INSERT.NAMESPACE.HERE.\* "

(include the quotes)

That's it.

Craig Peterson's answer is correct. N.B. However! The tab 'importance' is not always visible from Session/Session-settings. Always, from inside a Folder list view, it will not be there. It seems there are certain filetypes that do not have it either, though I'm less clear on that. BC has so many options and plugins I bet there is a workaround, but for me I have been ok so far. http://www.scootersoftware.com/vbulletin/showthread.php?t=8457
