Simple StringRegExp logic (if text in file not found then...)

8 posts in this topic

I recently migrated from a batch file world.

So, for an autoit code such as:

If StringRegExp($read, "MultiServer = yes") Then Exit

All I would have to do is insert the word NOT to get what I want done....

If NOT StringRegExp($read, "MultiServer = yes") Then Exit

So, what's the simplest possible way to say if "MultiServer = yes" was not found in the text file to exit the autoit script?

I tried search for examples, but what I found looked unecessarily complex.

Thanks so much in advance!

Hi MKANET. Did you TRY If Not StringRegExp($read, "MultiServer = yes") Then Exit??

$read = "093606-CAR095193-NUR098927-ped101247-pedMultiServer = yes101713-car102902-car103244-ped103303-ped104739-car105276-car"

If Not StringRegExp($read, "MultiServer = yes") Then
MsgBox(0, "", "Not there")
Else
MsgBox(0, "", "It's there")
EndIf

Edit: Man I wish the page would update correctly when a new post appears ;)

I didn't presume it would just work; especially since I didn't find any examples. It turns out it works fine! I guess autoit is closer to batch files than I realized! Thanks for the tip!

It has to do with return values and true/false. In AutoIt, 0 or "" returns false while non-zero and non-empty string returns true. If you look at the help file notes on StringRegExp(), you'll see that by default, it returns 0 if it doesn't find it (false) or 1 if it does (true). So saying

If Not Function() Then [...]

also means If (function returns 0)

If Function() Then [...]

also means If (Function returns non-zero).

So if you do

If Not FileExists($file) Then msgbox(0,"","NOT HERE")

If it doesn't find a file the msgbox() will appear because FileExists() returns 0 if a file isn't found. Most of the AutoIt functions work in this manner. Always check the help file however because some return 0 when it worked and -1 when it doesn't... which goes against these rules because 0 matches false and -1 matches true. =/

I did a bunch of Internet searches before posting (which usually gives me the information I need); and, even saw the return value of 0 or 1. I just didn't know what the correct way of saying "NOT". I was too focused on finding the right regex for this and thinking I might have to do a condition for the value returned. ;)

If you see in my first post. I already guessed it exactly correct; which made perfect sense to me... I just didn't think there was a chance I could actually be right :)

But thanks very much for the examples!
