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.

Mittags zeit only

Finds all paragraphs in the input text, where a paragraph is defined as any occurrence of a non-whitespace character immediately following any of the following and any other preceding whitespace: 2 or more consecutive CRLF sequences 2 or more consecutive CR characters 2 or more consecutive LF characters 1 or more Unicode Paragraph Separator class characters The beginning of the string (matches the first paragraph) Again, note that whitespace mixed in with the above will not interfere with the matching, as demonstrated by the test text included. This is intended to be used with the options specified, so be sure to include them for best performance (non-backtracking, multiline, non-capturing, invariant culture). This will work effectively on any version of .net that supports the included syntax. However, it is intended for use with .net8.0 and up, with the Regex.EnumerateMatches() method, or, more ideally, with .net9.0 and up, using the new Regex.EnumerateSplits() method, to avoid allocations associated with Match objects. Unicode paragraph separator characters are very rare in practice and support for them is almost non-existent in software, including the Windows Console. Windows Terminal, web browsers, the Windows clipboard, notepad, Visual Studio, and notepad++, all of which fail to handle it in their own ways, none of them actually adding a line when they occur (though notepad++ will show it as PS if you have enabled showing all whitespace). It is safe to remove |\p{Zp}+ from the pattern, if you do not wish to include those characters in your search. The resulting pattern, as a c# string, would be: "((\\r\\n|\\r|\\n){2,}|\\A)^\\s*\\S"

Description Inspects lines that contain only a character, let's say c, repeated n times. The name of the matching groups will tell you if n is 0, the unit 1, a prime number, or a composite number. Alternative Removing the outermost anchors ^ and $ from the first (and very large) alternate group will do the same but, instead of inspecting per line, it will inspect any repetition of a character (line breaks, obviously, stop repetitions). ^(?: ...... )$|(?^$) to (?: ...... )|(?^$)
