Can I turn off multiline matching?

Can I turn off multiline matching for wildcards?

I.e., when I use .* in a regex, I want the .* to only match within one line.

Can't reproduce in TextPad 8.4.2, and as per regex defaults the dot matches anything but linebreaks. How is it possible for you having this problem at all?

Hint: using "Configure > Word Wrap" to display one original line in multiple virtual lines still doesn't make them multiple lines in real - that's only an optical feature (as can be seen by the line numbers) and out of scope for regular expressions.

Good question. I have Textpad 8.2.0 64-bit edition- about to upgrade it to see if that helps...

Oh-- I'm sorry- I did mis-state the problem a little bit. The issue is when I search for a negated character group- then it includes new lines. I.e., if my file is this :

ab
cd

and when I search for :

a[^x]*d

Then it selects both lines. I couldn't figured out how to also exclude new lines...

Never mind though- got it to work. I re-started Textpad, then tried searching for :

a[^x\n]*d

and that couldn't find a match.

I was sure I had tried that before restarting Textpad and it would still select both lines. Maybe restarting Textpad helped- or maybe I'm a little crazy.

Thanks.

Again that is no TextPad related behaviour, but a default in regular expressions:

• The dot matches anything but newlines.
• Classes match everything, either inclusive or exclusive - that's why \n needs to be added to either something which should be included or excluded.

Example: using . is equivalent to [^\n\r]

[ben_josephs]

I think you meant that . (dot) is equivalent to [^\n\r] (any single character other than line feed or carriage return).
\p in a [...] character class means just p .

[AmigoJack]

Oh yes, I meant \r instead of \p.

\p (and \P) are legit escape sequences for Unicode properties, if TextPad would support them.

[ben_josephs]

TextPad does support them. The following are equivalent
\pd
\p{digit}
[[:d:]]
[[:digit:]]
Each of them matches a single digit.

(this derails the topic, but)

I made my assumption from examples of something simple like \p{Pf} and \p{Greek} and \p{InHebrew}, which all gave me an error message about a wrong expression (instead of hinting it doesn't support the given property).

Neither the page I linked to, nor Perl itself lists a property named "digit", and unsurprisingly \p{digit} fails to match 一�, but that's the whole sense of Unicode properties: to i.e. match numbers of all languages, not just being another synonym of \d.
