Couldn't the confusing wording be fixed without additional information? As I understand it, the problem with the current message is that the in '⏏~' (indicated by ⏏) part leads people to think it's referring to a position in the source code, when it is actually referring to a position in a string. Especially because the "in block ... in file ... at line ..." line comes directly after it.
[perl #132232] [UNI] ignorecase returns too many graphemes for expanding foldcase graphemes

This is because 'fi' expands to 'f' + 'i' under foldcase.

See failing tests in S05-modifier/ignorecase.t Please note, for reasons I am not sure of, sometimes this will work if you try and do it yourself in the REPL for instance. This needs more investigating, but today I have not been able to figure out what is going on. Help wanted.

[perl #125500] [SEGV] double free or corruption, invalid pointer
I'll close this ticket. I'm failing to reproduce the issue on 2015-ish versions of rakudo, let alone HEAD. I think the actual problem was resolved and hopefully there are tests for it, but trying to find what exactly fixed it is a total waste of time unfortunately. Even with all powers of whateverables this is not going to happen. Maybe I can try bisecting it manually, but I know that it will just point to a random moar/nqp bump and that will be it. We'd much rather spend time on new SEGV tickets than this one.

[perl #125596] [LTA] error message with if; and unless; without conditions
Oof. I'm wondering why is it a .sorry and not .panic. Panic will blow up immediately with a good error message, but I think there's some reason for it to be a sorry. I can't figure out what it is exactly. Maybe something about subs called “if”? I tried various ways to trigger it erroneously but couldn't come up with anything useful. In any case, you may be wondering why it prints it 4 times.

[perl #125641] [LTA] error messages when right bracket is missing: $<> , <>, () and so on
See this pull request: https://github.com/rakudo/rakudo/pull/1183 Unfortunately not all of the things are covered. For example: perl6 -e 'my $x = q:to/foo/; blah ' ===SORRY!=== Error while compiling -e Ending delimiter foo not found at -e:3 --> ⏏ expecting any of: whitespace Then there's also: * https://github.com/rakudo/rakudo/blob/f62ae60c48d1372df18b49aca44e10af44ead2d6/src/Perl6 /Grammar.nqp#L3741 * https://github.com/rakudo/rakudo/blob/f62ae60c48d1372df18b49aca44e10af44ead2d6/src/Perl6/Grammar.nqp#L3780-L3792 * https://github.com/rakudo/rakudo/blob/f62ae60c48d1372df18b49aca44e10af44ead2d6/src/Perl6/Grammar.nqp#L3820-L3826 And maybe other things too. For example, nqp itself prints a similar error message and does not mention the starter. I don't know if any user will ever see the error message from NQP though. So there's a lot to be done to resolve this ticket fully… Oh, also! I did not remove “expecting any of:” part. This has to be done also.

FWIW for those wondering how exactly it was resolved, here's the commit: https://github.com/rakudo/rakudo/commit/382c78a97ae6132d0054e0112cf19ceb2d50fef6 On 2016-12-10 10:10:48, c...@zoffix.com wrote: > Tests now exist: > https://github.com/perl6/roast/commit/da6fde44ab97cdcbb50bf181528f55671914612c
[perl #131814] quote bug in shell command on windows
There does seem to be a quoting bug in Windows shell but none of the above examples show it. See #132183: Insufficient debug messages from zef/perl6.bat when package build fails I propose this ticket be closed.
[perl #131814] quote bug in shell command on windows
I don't think this is a bug in the shell command on windows since cmd.exe behaves differently to Bourne type shells. UNIX $ echo "foo" foo Windows C:\Windows\system32>echo "foo" "foo"
[perl #125674] [LTA] error message prints wrong eject position (if True if { };)
This one is a bit harder than it seems.
So here is what throws:
https://github.com/rakudo/rakudo/blob/f62ae60c48d1372df18b49aca44e10af44ead2d6/src/Perl6/Grammar.nqp#L315
However, the cursor has wrong position for some reason. Looking at the lines
above, it may seem that doing this:
self.'!cursor_pos'($pos);
should fix the problem… but it doesn't! $pos variable is set correctly, but
!cursor_pos does absolutely nothing. In fact, you can try setting it to 0 or
any other value, no effect whatsoever.
This suggests that the use of !cursor_pos in the same method does not work too.
What is the right way to set the cursor?
And why does the cursor even have the incorrect value there?
As a bonus, this line seems to be unreachable:
self.missing("block (taken by some undeclared routine?)");
I tried various things but nothing can trigger it. I found (via google) some
code snippets that used to result in this error message, but nowadays it simply
says “Missing block”. I bisected that change to
