rcmlz habere-et-disper: did you try to create a nix file (package) that sets up rakudo, zef and packages - like rakudo-star does outside of nix? Or did you try to use rakudo-star from nix? 08:02
do you have the file you are working on (default.nix, shell.nix, …) on some public space? 08:03
Nix and the underlying concepts are not easy to grasp - but addictive. I also fiddle around with NixOS/Nix-Packages on beginners level, perhaps I can have a look. 08:07
nahita3882 today i learned that Raku has a (kind of) built-in identity function: [o] or [∘] 13:56
can we catch the "potential difficulties" things? is that an error or a warning or something else? 14:04
for example: say 02;
antononcube That is interesting -- I would occasionally "miss" having an identity function in Raku. 14:13
.landyacht. I think that’s compile time so probably not 16:50
nahita3882 hmm, so I can CATCH some (all?) compile-time errors under, say, .EVAL, but this is like a compile-time warning and there is no mechanism for that? 17:28
m: CATCH { default { say $_.is-compile-time } }; "&unknown()".EVAL 17:29
Raku eval Exit code: 1 ===SORRY!=== Error while compiling /home/glot/main.raku Undeclared routine: unknown used at line 1
nahita3882 m: CATCH { default { say $_.is-compile-time } }; Q|&unknown()|.EVAL
Raku eval 1
nahita3882 m: CATCH { default { say $_.is-compile-time } }; Q|02|.EVAL 17:30
Raku eval Potential difficulties: Leading 0 has no meaning. If you meant to create an octal number, use '0o' prefix; like, '0o2'. If you meant to create a string, please add quotation marks. at /home/glot/EVAL_0:1 ------> 02⏏<EOL>
ab5tract nahita3882: I think this works? 19:27
m: BEGIN CATCH { say "caught $_" }; my Int $x = "ok"
camelia caught Type check failed in assignment to $x; expected Int but got Str ("ok")
Type check failed in assignment to $x; expected Int but got Str ("ok")
in block <unit> at <tmp> line 1
ab5tract but make sure you keep it as a thunk, or else the CATCH is installed underneath the scope you actually intended
Sorry, disregard that as these are not addressing compile time 19:30
