- OR condition in Regex - Stack Overflow
For example, ab|de would match either side of the expression However, for something like your case you might want to use the ? quantifier, which will match the previous expression exactly 0 or 1 times (1 times preferred; i e it's a "greedy" match) Another (probably more relyable) alternative would be using a custom character group:
- Regular expression to stop at first match - Stack Overflow
you can match a[^ab]*b i e specify a character class which excludes the starting and ending delimiiters In the more general case, you can painstakingly construct an expression like start(|[^e]|e(|[^n]|n(|[^d])))*end to capture a match between start and the first occurrence of end
- Regex: ignore case sensitivity - Stack Overflow
G[a-b] * i string match("G[a-b] *", "i") Check the documentation for your language platform tool to find how the matching modes are specified If you want only part of the regex to be case insensitive (as my original answer presumed), then you have two options:
- How do if statements differ from match case statments in Python?

- Regex - how to tell something NOT to match? - Stack Overflow
OK, but of course then the match result will be an empty string (with a successful match) If you're just checking whether a match is possible, then this doesn't matter So yes, omit the *$, and you're done faster –
- How can I compare two lists in python and return matches
A quick performance test showing Lutz's solution is the best: import time def speed_test(func): def wrapper(*args, **kwargs): t1 = time time() for x in xrange(5000): results = func(*args, **kwargs) t2 = time time() print '%s took %0 3f ms' % (func func_name, (t2-t1)*1000 0) return results return wrapper @speed_test def compare_bitwise(x, y): set_x = frozenset(x) set_y = frozenset(y) return set
- Reset local repository branch to be just like remote repository HEAD
Setting your branch to exactly match the remote branch can be done in two steps: git fetch origin git reset --hard origin master If your default branch is main (GitHub changed the default branch name from master to main starting October 1, 2020): git reset --hard origin main
