Case-sensitive search in Regex mode?

Doitsu · 01-03-2013, 10:57 AM

I noticed that Sigil 6.2 won't find a capitalized word if Regex mode is selected.
For example, if I search for "test" it wont find "Test" in this example paragraph:

<p>This is a Test.</p>

However, it'll find "Test" if I switch to Normal mode.

I wondering whether this is by design or a bug, because the Editors with PCRE engines that I've seen so far all default to case-insensitive searches in Regex mode.

start with (?i) <- case insensitive

but you are discussing what should be the default, right

I don't know. It seems to me that regex, by design, is case insensitive. That's why you have to add flags/switches to force it to be case insensitive. Almost all apps I use that have some sort of regex engine put the onus on the user to specify they want case insensitivity. Non-regex search engines always seem to default to case insensitive though.

(?i) indeed works fine.

Yes.

That was my assumption, too. But then again, I'm not exactly a regex guru.

I think there's an "in" too many.

I don't know what should be the default, but I'm used to my case-sensitive vim settings.

Oops! You're correct. I meant "regex, by design, is case sensitive"... unless you tell it to behave otherwise.

That's what I'm used to as default.

well when using the "replace" part of regex, you want some control over the case used in the replacement strings - so case sensitive is surely a sensible default
