Find and Replace via PythonScript on subfolders

SpecialCharactersEnjoyer

NPP Find & Replace doesn’t support mathematical operations and recommends(?) doing it using a PythonScript plugin. Fair enough, I went and got myself the script:

def multiply2(m):
    return 'Mass="' + str(float(m.group(1)) * 2) + '"'

editor.rereplace('Mass="([0-9]+(?:\.[0-9]+)?)"', multiply2);

I tested it, it works, I’m happy. Unfortunately, I need to run this script on over 1700 files in like 100 different subfolders and I’m stumped. For some reason I thought it would be as easy as opening the main folder as a Workspace but that was perhaps a bit too optimistic.

@SpecialCharactersEnjoyer ,

You would have to program a loop around the editor.rereplace where you have PythonScript open a file, run the editor.rereplace, save, and close, then move on to next file.

Since you have 100 directories with a total of 1700 files, you would have to probably have a double-nested loop, with the first loop going over the directories, and the second loop going over the files in each directory.

That looping portion is a generic Python coding question, and isn’t specific to Notepad++ or the PythonScript plugin (ie, the answer doesn’t change if you’re using python.exe instead of using Notepad++ and the PythonScript plugin), so you can search the internet for general Python-language help on how to write loops in Python that loop over all (matching) files in all (matching) directories.

In addition to what Peter said, inside your loop you would call notepad.open(), then do your replacement(s), then call notepad.close().
