How to match the end of a line?

Question

How can I say to match all specific character sets, or EOL?

[=]+.*?[()|$]

matches: ==test)

does not match: ==test

Why doesn't the end of the regex anchor $ line count for the second statement?

Answer 1

The end of the line does not work in the character class, because it is not a character. This is a zero-width statement (it checks the condition at the current point in the line, but does not actually use a character).

Test it with (?:otherstuffhere|$) .

Note. It seems you are mixing a character class with the corresponding subgroup. A character class [...] matches any character in brackets. [a|bc] will match either a , | , b , or c . Relevant subgroups are what you want or multiple expressions. (...) is the corresponding subgroup with capture. (?:...) is the corresponding subgroup without capture.

Note that the $ matching behavior may vary in a multi-line string based on your settings. It can either match the end of each line, or just the end of the line.

\z will always match only at the end of a line, no matter what settings you use. \z will match either at the end of a line or just before a new line at the very end.
