Analyze whether the torrent name is a Movie or TV Episode Inspired from https://regex101.com/library/yP4bY4 There is two versions, see differences at the bottom Groups: Title (of the Movie/of the TV Series) Season (if TV Episode) Episode (if TV Episode) Year (if Movie) Name (only in v1, should match the TV Episode title if present) Release name (PROPER, REPACK, LIMITED, etc..) Resolution (720p, 1080p, etc..) Quality (HDTV, BluRay, WebRip, etc..) Codec (Xvid, x265, x264, etc..) Audio coding (AAC, AC3, DTS, etc...) Team (torrent group/team) Extension (mkv, avi, mp4, etc...) Versions: v1, include the TV Episode title, and have all the groups in a single match, but will misinterpret the "name" and "team" groups if the expected pattern is not respected (see in the test strings/regex rules) v2, does not include "name" group but is more reliable, will ignore unexpected patterns.

This validates AWS EventBridge scheduling expressions using the rate() and cron() formats. It may not catch all invalid expressions, but it should properly validate all valid expressions, as demonstrated in the unit tests. Please let me know if I missed any valid expressions. Originally attempted this using named capture groups and named back-references to reduce duplication. Unfortunately, named capture support is tricky, so they were all converted to duplicated non-capturing groups instead.

Parses an IANA Media Type value. Doesn't seem to capture repeating parameters, which is a bit of an edge case but valid I think - any suggestions on how to fix would be appreciated.

Replaces ^ with Math.pow function call. This assumes all braces have been combined first. If you need help with the combination, I got you—try this Python algorithm: def evaluate_braces(expr): """Recursively evaluate expressions within braces""" Check if expression contains braces if '(' in expr: Find the innermost set of braces left = expr.rfind('(') right = left + expr[left:].find(')') Evaluate the expression within the braces result = eval(expr[left+1:right]) Replace the expression within the braces with its result expr = expr[:left] + str(result) + expr[right+1:] Recursively evaluate any remaining expressions within braces expr = evaluate_braces(expr) Evaluate the final expression return expr expression = "31+((4+1)+27)2" result = evaluate_braces(expression) print(result) # Output: 2+2+3+4*8/2

(^([0-9]{2,3}.)([0-9]{2,3}.)([0-9]{2,3}.)([0-9]{2,3})$)

A proof of concept regex that captures dates and date ranges with a variety of separators. Works with both DMY and MDY, and if one is not needed, it can be easily deleted from the regex. The full variety of months needs to be implemented by the programmer themselves since developing it in regex101 is unfeasible and would clutter the regex.

Here's a regular expression to handle a specific year in the different forms of dates: YYYY-MM-DD DD-MM-YYYY MM-DD-YYYY

A general regular expression that uses the keywords 'Facebook' and 'id' to collect strings that contain Facebook IDs. Also, added an additional condition to where if there's a long numeric string it will be match a group given that, 'Facebook' is within the string.
