I have a question. How can I make a regex that searches for an entire string? I've used regex's to search for symbols and specific stuff like email addresses and whitespace.

However, I just faced a new issue. How can I use a regex to search for an entire string like "omnimaga.org"? Thanks.

I am using PCRE indeed. I tried "\\mystring/", but it didn't really work. Any idea? Thanks.

Is "\\mystring/" the literal you typed in?  That will search for "\mystring/".  If you are specifically trying to regex out websites, you can try something like "www(\..+)*" for instance.

No, it's not a website, the "omnimaga.org" was a bad example, let's try "omnimaga". I would have "\\omnimaga/" as the literal string, so that the \\ turns to a \. Is that alright to look for omnimaga? Thanks.

{this is a pattern}
I also found online patterns in PCRE should be like that, but it's not working either.

I'm still not sure if your after 'omega' or '"omega"' (do you want to include the quotes?). If it's just 'omega', then the regex is just 'omega'. That means your looking for an o, followed by an m, followed by an e, followed by a g and then an a.

In some languages you then have to format it in a special way, such as in JavaScript you add a / on either side, so it becomes /omega/. In PHP you do the same, and then put it inside a string, so it becomes "/omega/". Just be aware that the / wrapping is a convention used by languages to state that it's a regex, and not the regex it's self. As a result different language have different rules.

If you want to use special characters, such as [, ., ^, /, \, $, * or +; then your right that you append a \ before it. However in some languages the \ already means something, such as "\n" is a new line in Java and PHP. So in those languages you have to escape the slash. For example the regex '\.omega' would become '\\.omega' in Java and (I think) PHP.

If you state what language your working in, then more accurate help could be provided. There are also plenty of online regex testers available online, such as this one here.

I'm working in Vala. I realized saying that was a bit useless because I said I'm using PCRE. Isn't PCRE what defines how it works?

I think in Vala I just need the "omega" by the way.

Jim, RegEx patterns are placed in strings in Java. They are not wrapped with //.

I am aware. Your comment sounded like a general statement about RegEx to me, in which case it is false.

I'm sorry, should have mentions the RegExp type.
Indeed you had a valid statement.
