IsAstack ( )

I need a robust alternative to if there is a stack pFilePath that does *not* load the file into memory and potentially cause problems with shared stack name space. Can anyone improve or see anything not foolproof with this? function isAstack pFilePath return line 1 of

Re: IsAstack ( )

Only problem I see is that you are going to get false positives if the file actually IS a shell script. You might try nibbling a little more to get something Metacard/Rev specific. Also, I know the file format has changed a couple of times in recent history -- you might need to check if

Sorry. Ignore my first try. It fails already. (-: Dave ___ metacard mailing list metacard@lists.runrev.com http://lists.runrev.com/mailman/listinfo/metacard

Re: The Challenge (was whole(string) is in a fld)

Hi Hugh Usual technique to seek extra time from a client is to ask more questions. :-) I assume the string has to match on the start of a word boundary. e.g. put This is a test. into sourceText (note the punctuation) whole(is is a test,sourceText) = FALSE Case-sensitivity? Dave On

These are the functions I have: function stack_Exists someName -- will not add stack to memory set lockmessages to true put the mainstacks into stacksInMemory put empty into shortStackName if exists(stack someName) then put true into safeExistence put

Re: The Challenge (was whole(string) is in a fld)

Hi Dave, Case sensitivity is an optional extra (although international should, if possible, be handled for those who use accents). Depends on how brave you are feeling. :-)) Challenge reminder... put This is a test-piece. into sourceText (note the punctuation and hyphen) whole(This is a

Re: IsAstack ( )

Hi Klaus, Brian, David: Good catches. I don't think I dare use open/read/close in case the file (and it could be any file) is in use, and testing the suffix is not always reliable (I am allowing data stacks to be suffix-less). Since I've never used a shell script, I'm not sure what

Hi Hugh I think I wrote those mails a long time ago from the wrong address and they've just been allowed through now. Sorry if they prompted you to respond. Cheers Dave Hi Dave, Case sensitivity is an optional extra (although international should, if possible, be handled for those

Re: IsAstack ( )

Yes it does - which is why the script deletes the stack from memory if it was not already loaded before hand. I use this script routinely when looping through indexes of stacks which may have been moved or deleted by hand, and wrote it to avoid the problem of loading everything into memory - I am

Re: IsAstack ( )

Hugh, I had one last thought while reading this that might be a clever approach. Read a little bit off the front of the currently running stack (since you KNOW that's a valid stack) and compare it to the file in question. The advantages are that you only have to read a tiny bit of the
