| 2026-03-01 11:40:27 +0100 | <mauke> | that is, posix is fine with []\-], but in Haskell you need to write it as "[]\\-]" |
| 2026-03-01 11:40:02 +0100 | <mauke> | \ must be escaped in Haskell strings, but does not need to be escaped in [ ] |
| 2026-03-01 11:39:40 +0100 | <opqdonut> | yep, pretty trippy |
| 2026-03-01 11:39:32 +0100 | <Milan_Vanca> | ] must be first - must be last, \ must be escaped and ^ must not be first |
| 2026-03-01 11:39:11 +0100 | <mauke> | this is why every regex library written after ~2000 ignores posix and just does what perl does |

| 2026-03-01 11:38:59 +0100 | <Milan_Vanca> | Lets say I need to also include literals - ^ \ then it should look like "[]a-z^\\-]" |
| 2026-03-01 11:37:42 +0100 | <opqdonut> | regex(7) says: To include a literal ']' in the list, make it the first character |
| 2026-03-01 11:36:58 +0100 | <opqdonut> | regex-tdfa says it implements posix extended regexes, which need []a] |
| 2026-03-01 11:36:44 +0100 | <Milan_Vanca> | You are right using ^$ produces False. Now it all makes sense |
| 2026-03-01 11:35:53 +0100 | <Milan_Vanca> | Yeah..probably I am going to test ^$ |
| 2026-03-01 11:35:28 +0100 | <opqdonut> | I think what might be happening is that "a]a" =~ "[a\\]]{1,3}" is really matching "[a]]{1,3}", that is, "a]" |
| 2026-03-01 11:35:12 +0100 | <Milan_Vanca> | Yeah I think I see now. |
| 2026-03-01 11:34:50 +0100 | <opqdonut> | note that =~ checks if any match is found, it doesn't necesarily match the whole string |

| 2026-03-01 11:33:51 +0100 | <opqdonut> | I don't know about Text.Regex.TDFA in particular, but in most regex implementations you need to write that character class as []a] |
| 2026-03-01 11:32:38 +0100 | <Milan_Vanca> | The last one should also produce True? |
| 2026-03-01 11:32:20 +0100 | <Milan_Vanca> | Hello guyz, not sure if I found bug in library or I am just dumb but for import Text.Regex.TDFA and these equations "aaa" =~ "[a]{1,3}" -> True, "a]a" =~ "[a\\]]{1,3}" -> True, "aaa" =~ "[a\\]]{1,3}" -> False |
