Strip leading zeros

Hello there!

I would like to strip the leading zeroes from my six-digit file names.  Eg 000001, 003241, 097845, 243546 would become 1, 3241, 97845, and 243546.  I did search in the forum and in Renamer itself - I think it might be in RegEx - but couldn't see how to do it.  Great program & thanks in advance for any assistance.

You can really use RegEx.
The pattern is easy in ReNamer because you don't have to match the whole string but only what you really need:

1) RegEx: Replace expression "^0+" with "" (skip extension)

Explanation:
^ --> match at start of string
0 --> match one literal digit '0'
+ --> match one-or-more of the pattern right before, here the '0'

So we will match one or more of leading zeros, if any, and replace them with nothing, meaning removing them.

HTH?

Note:
you can use "Preset > Save as..." to store that rule for later use
or use an PascalScript saved to an file into the Scripts sub-folder for the very same purpose:

begin
//ReplaceRegEx(Input,'Find', 'Replace', CaseSensitive, UseSubstitution)
  FileName :=  ReplaceRegEx(FileName, '^0+', '', False, False);
end.

Re: Strip leading zeros

Hi Stefan

Thanks, that works perfectly!  What a powerful program.

Just typing in three characters and a few clicks to do the entire job!  Remarkable.

Best wishes

PS Your examples are better than mine, aren't they - it was of course important to retain the non-leading zeroes as you showed.
