| grondilu | Hello. Please look at this gist.github.com/grondilu/ebceff32e...fdb4516f24 and tell me what I am missing. | 03:30 | |

| grondilu | basically I'm trying to catch a pattern in a multiline string but the regex grabs all the trailing newlines. | 03:31 | |
| m: say grammar { rule TOP { ^ <line>+ $ }; rule line { <.alpha>+ } } .parse: "foo\n" | 03:37 | ||
| camelia | ｢foo ｣ line => ｢foo ｣ |
||
| grondilu | how can I extract "foo" and not "foo\n"? | 03:38 | |

| grondilu | in a nutshell I want to parse a file with blocks of text separated by empty lines. | 03:39 | |
| that can't work as I've tried if the regex catches trailing newlines. | 03:40 | ||
| guifa | I would use token instead | 03:42 | |
| or change <ws> to be \h | |||
| so | 03:43 | ||
| say grammar { rule TOP { <line> %% \n }; rule line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n" | 03:44 | ||
| m: say grammar { rule TOP { <line> %% \n }; rule line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n" | |||
| camelia | ===SORRY!=== Error while compiling <tmp> Missing quantifier on the left argument of %% at <tmp>:1 ------> say grammar { rule TOP { <line> %%<HERE> \n }; rule line { <.alpha>+ } } .parse: |
||
| guifa | m: say grammar { rule TOP { <line>+ %% \n }; rule line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n" | ||
| camelia | Nil | ||
| guifa | m: say grammar { token TOP { <line>+ %% \n }; token line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n" | 03:45 | |
| camelia | ｢foo bar xyz ｣ line => ｢foo｣ line => ｢bar｣ line => ｢xyz｣ |
||
| grondilu tries | |||

| camelia | Nil | ||
| grondilu | there is no empty line in "foo\nbar" | ||
| ugexe | <.alpha>* | 03:55 | |

| grondilu | m: my $pgn = "e4 e5\n\ne4 d5\n"; $pgn.match(/[<ident>+ % <ws>]+ % [^^$$]/) | 09:54 | |
| camelia | ( no output ) | ||
| grondilu | m: my $pgn = "e4 e5\n\ne4 d5\n"; say $pgn.match(/[<ident>+ % <ws>]+ % [^^$$]/) | ||
| camelia | ｢e4 e5 e4 d5｣ ident => ｢e4｣ ws => ｢ ｣ ident => ｢e5｣ ws => ｢ ｣ ident => ｢e4｣ ws => ｢ ｣ ident => ｢d5｣ |
||
| grondilu | m: my $pgn = "e4 e5\n\ne4 d5\n"; say grammar { regex TOP { [<ident>+ % <ws>]+ % [^^$$] } }.parse: $pgn | 09:55 | |
| camelia | Nil | ||
| grondilu | yet it's the exact same regex! | ||
| grondilu throws hand in the air in despair | 09:56 | ||

| kathe | Hello to everybody. :) | 12:25 | |
| timo | greetings | ||
| kathe | I don't know if Mr Wall hangs out over here anymore. In case he still does: | 12:26 | |
| I tasted "Pepsi" yesterday, and honestly, I liked it. | |||
| As opposed to my preference from ThumbsUp and Coca Cola. | 12:27 | ||
| The Pepsi people have made some changes to their formula, | |||
| as far as the Indian market goes. It is not as sweet as it used to be before. | 12:28 | ||
| Alrighty, bye to everybody, and I hope Raku not just survives, but also thrives. | |||
| Have a great time ahead. :) | |||
