Some text matching questions

(!$SET(#=.))+{1,*}

1. Match !
2. Set stack to .
3a. + says "Repeat 1 and 2".
3b. {1,*} says "Must match once, Match all."

The 1 is needed because !+ would match ! or nothing.

"space and", space?

What happens, if you use PrxNeverMatch(^?) and PrxNeverMatch is the last thing?

I think I've got it now. Thanks.

The space comment came from looking at your post in the white code view box. There appeared to be a space after the "." But after copying it and pasting into a text editor, the space disappears. Probably a monospace vs proportional font difference.

There is a really really really small posibility you could find prxnevermatch in a web, but the posibility is there. So to be sure about it will never match, it's better to use PrxNeverMatch(^?) or PrxNeverMatch$TST(), because (^?) or $TST() NEVER will match.
So, using PrxNeverMatch$TST() (or PrxFail$TST() like sidki does) you will have the faster speed and most security

(^?) will match. I use it.

Code:

[Patterns]
Name = "Test (^?)"
Active = FALSE
Limit = 256
Match = "prxnevermatch(^?)"
Replace = "Gotcha"

Testing:

Code:

prxnevermatch
prxnevermatch

Result:

Code:

prxnevermatch
Gotcha

I agree.

Wow! Thanks for that i wasn't know.
I was playing with your filter and if we set 13 as byte limit, then will match twice (gotcha gotcha)

I take note, updating my filters

[lnminente]

Could someone explain me why this happens?

Create a new filter and use this as matching code:
(
<$SET(open=1)|
>$SET(open=)
)PrxFail$TST()|
?(^$TST(open=1))

Go to the test window and paste this:
<font color="pink">BLA</font>
<font color="pink">BLA</font>
BLA BLA BLA
<font color="pink">[table]</font>
BLA BLA BLA
<font color="pink">[table]</font>

The result in the test windows is:
<font color="pink"</font<font color="pink"</font<font color="pink"</font<font color="pink"</font

It matched the > symbols!!
To have this working i add (^>) before ?, but i would like to know why the first doesn't work. Maybe it was too fast and proxomitron had no time to set open=nothing?

[z12]

Code:

(^$TST(open=1))

When proxo sees the > character, var open is cleared.
Then, $TST(open=1) evaluates to false.
Not false = true
Match!

Afterwards, proxo matches every character till the next < character.

Hi z12!
I was investigating some troubles with global variables (like Inside_Script and Inside_Link) using other filters with multi activated... Now i come mind refreshed and see it clear . I was not considering than the filter works exactly for the caracter wich goes after > than for the >.
Many thanks for your help

[z12]

Glad I could help.
