From 4e21b49994ba031e0716568c38681c3c5b83bbc0 Mon Sep 17 00:00:00 2001 From: senritsu Date: Sun, 17 Jan 2021 20:24:23 +0100 Subject: [PATCH] adjust episode path expression to allow digits in series names The previous expression was too greedy to consume digits, because the hyphen was optional. This lead to incorrect episode numbers for certain series with digits in their names, in those cases each episode was recognized as the same episode number (the digit from the series name). The rule, which matches most standard anime filenames, also had a lower priority than one of the Kodi rules, leading to incorrect recognition for absolute numbered episodes with triple digits and higher (first digit was used as season number, rest of digits as episode number). This also resolves one of the TODO test cases. Additional test cases were added to ensure that both hyphens in different parts of the filename, as well as names without hyphens, still work correctly. All previous test cases still pass. Unfortunately another TODO (EpisodeNumberTests.cs@L76, Uchuu Senkan Yamato 2199) with the same issue (digits in the series name) could not be trivially fixed in the same change, due to the significantly different formatting. Attempts to resolve this case did not work out for now. --- Emby.Naming/Common/NamingOptions.cs | 13 +++++++------ .../Jellyfin.Naming.Tests/TV/EpisodeNumberTests.cs | 6 +++++- 2 files changed, 12 insertions(+), 7 deletions(-) diff --git a/Emby.Naming/Common/NamingOptions.cs b/Emby.Naming/Common/NamingOptions.cs index 035d1b22801..ba4446ff11b 100644 --- a/Emby.Naming/Common/NamingOptions.cs +++ b/Emby.Naming/Common/NamingOptions.cs @@ -282,7 +282,13 @@ public NamingOptions() SupportsAbsoluteEpisodeNumbers = true }, - // Case Closed (1996-2007)/Case Closed - 317.mkv + // Not a Kodi rule as well, but below rule also causes false positives for triple-digit episode names + // [bar] Foo - 1 [baz] special case of below expression to prevent false positives with digits in the series name + new EpisodeExpression(@".*?(\[.*?\])+.*?(?[\w\s]+?)[\s_]*-[\s_]*(?\d+).*$") + { + IsNamed = true + }, + // /server/anything_102.mp4 // /server/james.corden.2017.04.20.anne.hathaway.720p.hdtv.x264-crooks.mkv // /server/anything_1996.11.14.mp4 @@ -299,11 +305,6 @@ public NamingOptions() // *** End Kodi Standard Naming - // [bar] Foo - 1 [baz] - new EpisodeExpression(@".*?(\[.*?\])+.*?(?[\w\s]+?)[-\s_]+(?[0-9]+).*$") - { - IsNamed = true - }, new EpisodeExpression(@".*(\\|\/)[sS]?(?[0-9]+)[xX](?[0-9]+)[^\\\/]*$") { IsNamed = true diff --git a/tests/Jellyfin.Naming.Tests/TV/EpisodeNumberTests.cs b/tests/Jellyfin.Naming.Tests/TV/EpisodeNumberTests.cs index 5e023bdb068..921c2b1f57b 100644 --- a/tests/Jellyfin.Naming.Tests/TV/EpisodeNumberTests.cs +++ b/tests/Jellyfin.Naming.Tests/TV/EpisodeNumberTests.cs @@ -66,12 +66,16 @@ public class EpisodeNumberTests [InlineData("Season 2/2.
