In this update of my translate program, I added support for searching and replacing with regular expressions.

Option -r (regex) uses a regular expression to search through the file and then calls the provided function with a match argument for each matched string. The return value of the function (a string) is used to replace the matched string.
Option -R (filterregex) is similar to option -r (regex), except that it does not operate on the complete file, but on the file filtered for the regex.

Here are 2 examples with a regex. The input file (test-ah.txt) contains the following: 1234&H41&H42&H43&H444321

The first command will search for strings &Hxx and replace them with the character represented in ASCII by hexadecimal number xx:
translate.py -r “&H(..)” test-ah.txt “lambda m: chr(int(m.groups()[0], 16))”
Output: 1234ABCD4321

The second command is exactly the same as the first command, except that it uses option -R in stead or -r:
translate.py -R “&H(..)” test-ah.txt “lambda m: chr(int(m.groups()[0], 16))”
Output: ABCD

In this output, strings that do not match the regular expression are filtered out.

I added support for ZIP files to decode-vbe.py

Here is the man page:

Usage: decode-vbe.py [options] [file]
Decode VBE script

Options:
–version   show program’s version number and exit
-h, –help  show this help message and exit
-m, –man   Print manual

Manual:

This program reads from the given file or standard input, and converts the encoded VBE script to VBS.

The provided file can be a password protected ZIP file (with password infected) containing the VBE script.

The content of the VBE script can also be passed as a literal argument. This is similar to a Here Document in Unix.
Start the argument (the “filename”) with character # to pass a literal argument.
Example: decode-vbe.py “##@~^DgAAAA==\ko$K6,JCV^GJqAQAAA==^#~@”
Result: MsgBox “Hello”

It’s also possible to use hexadecimal (prefix #h#) or base64 (prefix #b#) to pass a literal argument.
Example: decode-vbe.py #h#23407E5E4467414141413D3D5C6B6F244B362C4A437F565E474A7141514141413D3D5E237E40
Result: MsgBox “Hello”
Example: decode-vbe.py #b#I0B+XkRnQUFBQT09XGtvJEs2LEpDf1ZeR0pxQVFBQUE9PV4jfkA=
Result: MsgBox “Hello”
