Rather than worry about how many underscores are being replaced, I would simply look for all text that precedes the text you want to keep. In that way the same command will work no matter how many underscores you have. The simplest method is to use a look-ahead assertion. The regular expression veri...

Once you enable delayed expansion, it is often advisable to use it through out, and it certainly doesn't hurt to use it. The reason why it may be wise to use delayed expansion if it is enabled is because ! literals within variables will need to be escaped if you use percent expansion while delayed e...

First off, here is the minimum number of carets needed to get your existing code to work: REM Line without delayed expansion call :Write_Log - [Error] - The script isn't running under an administrator account or there has been no increase privileges ("Run as Administrator", from Windows Vista^^). RE...

It is a beast :twisted: You did well. The only added JREPL feature I used was the /T option. The rest of what I wrote deals with capture groups and look ahead assertions, which are standard regex constructs, not really JREPL specific standard batch constructs like FOR, FOR /F, variables, delayed exp...

aGermans' regular expression find/replace pair can be modified a bit to make it easier/shorter to write by using capture groups and lookahead groups. Something of the form: Capture Group 1 Look-ahead (BytesToMatchAndPreserve)ByteOrBytesToChange(?=AdditionalBytesToMatchAndPreserve) $1ReplacementBytes...

I have never heard of a "cardoid". Did you mean "cardioid"?

That shape is not a cardioid because it has two cusps, where as a true cardioid has one cusp. If the bottom was rounded instead of having a point then it could be a cardioid.

I've updated the first post in this tread to version 1.6.

The /F and /FR options now support non-ASCII characters (8 bit characters with the high order bit set).

Ouch, there may not be much that can be done. HASHSUM is totally dependent on native Windows command line tools, and they have inconsistent support for Unicode. It would help if you tell me which options you used when the code fails. Both the code to generate hashes and the code to check hashes are ...

I have only casually browsed this topic, so I may be barking up the wrong tree... But perhaps your problem has something to do with the intermittent XP bug when a FOR /F IN() clause contains an unquoted/unescaped token delimiter . Remember that one :!: :?: :twisted: I definitely see an unquoted/unes...

My previous post postulates that phase 2 checks to see if the first token is a batch script, and then the parser follows some alternate path if it is. At first I thought " Why the hell would phase 2 do that :?: :? " But then... of course :) Phase 2 is restarted if there is a CALL, and CALL needs to ...

I think i've read before that delayed Expansion "differs" between command and parameter string (although the consequences were different), but i cannot remember where; if i had to guess, i would say it was a post/code from jeb/dbenham/both - something like this: Yes, I described somewhere that the ...

So here is my current understanding of the label scanner process: 1) The label scanner attempts to read one line at a time, but it is limited to a 512 byte buffer, and it only recognizes \r\n as end-of-line. So when it reads a "line" of data, it reads through the first encountered \r\n, or end-of-fi...

I don't have time to do further investigation now, but I hope that these discoveries may help resolve one or both of these unexplained edge cases: Delayed expansion fails in some cases Examination of Linefeeds with CALL That was wishful thinking. I couldn't remember any details other than at least ...

Ooooh, a cmd.exe regression test plan :!: :D That would be nice, but I can't imagine actually doing it: 1) It would probably take thousands of individual tests 2) Documenting each test and showing how it relates to the rules would be difficult - there are lots of many to many relationships. I simply...

I'm not sure what you are attempting with your first two examples. But the last two give expected behavior - you cannot escape a quote once quoting has begun. So you can escape the first quote or the last quote, but not the middle one. Regarding my SO post that aGerman linked - the section on escapi...
