SrainUser How do I import a function from a local raku file? 01:23
I typed "unit module foo" and "is export" for the file to export the function. I typed "use foo" as an import statement for the other file. I get an error saying it could not find foo. 01:28
timo if it's a local file, you'll need to tell rakudo to look locally, usually by supplying `-I folder` (which shouldn't be a huge folder, like your entire home directory, because it will be scanned) 01:37
if you're in a module, meaning you have a META6.json, that's where you'd have to have an entry for your module foo in the "provides" section 01:38
01:44 guifa joined
SrainUser So a module in a file requires a META6.json file to tell raku to import from the current working directory? 01:44
timo no, there's a third way which is `use lib ".";` or `use lib "thefolder";` in the raku script 01:46
it will look for files named with .rakumod extension by default 01:49
gnite! 01:52
SrainUser It still does not find any module inside the ".rakumod" file. All I typed was "use lib ".";" and "use foo;" 01:57
timo mkdir /tmp/srainmodule; cd /tmp/srainmodule; echo "unit module foo; sub footest() is export { say 'success'; }" > foo.rakumod; echo "use lib '.'; use foo; footest()" > main.raku; rakudo main.raku 02:00
this one-liner works on my end
i've got to go sleep now, maybe this helps
if you set RAKUDO_MODULE_DEBUG=1 in the environment, rakudo will output debug lines related to module loading, it should have lines in it like "Successfully handled 'lib' as a pragma", "try-load source at ./foo.rakumod", and near the end "Performing imports for 'foo'" and "Imports for 'foo' done" 02:02
if it doesn't, maybe seeing where the success runs out helps figure out what's wrong
SrainUser Okay, Goodnight 02:03
timo o/
SrainUser I figured it out. The filename of the ".rakumod" file must be the name of the module it contains. 02:22
guifa xinming: I should make a module Token::IP-String 02:44
Would go nicely with a project I'm workin gon anyways

xinming m: my $s = "hello"; (S/hel/aaa/ with $s).say; (S/hel/bbb/ given $s).say; 08:38
camelia aaalo
bbblo
xinming In this example, they both work, So the only diff between 'with' and 'given' are, 'with' will try to test the definied'ness of the $s, 'given' will always do the S/// Is my understanding right? 08:39

Xliff Yep. 08:57

Methods .^name, .raku, .gist, or .say can be used to stringify it to something meaningful.

antononcube Is there any Raku module that tells (computes or retrieves) what are sunrise and sunset times of certain city or time zone? 16:18
tbrowder antononcube: see Astro::Sunrise 17:54
lucs Module loading question: gist.github.com/lucs/911dec0edc4df...00dd365ef1 18:01
ugexe probably because you are running code that prints in the mainline of a module 18:05
which would get run during precompilation
lucs Hmm...
Ah. 18:06
I can avoid doing that doctor. 18:07
Shouldn't hurt anymore :)

lucs Heh. When I first noticed it was doing that, I kept trying to modify the code to see what was going on, resulting in a new precomp each time, and the same result. 18:12
Running it as is, no duplication.

xinming Is it possible to die when var ia uniniailized? 19:38
timo depending on where in your code it is you have multiple ways to do it 19:39
you can have a :D type smiley on the type of the variable, then an assignment with an undefined value will throw an exception
xinming It's not assignment, It's just when I try to print a string, the string has many vars, So it reports one of them uninitialized. I want the script to die with use of that var when print 19:42
timo ah, your print is a long command with a bunch of variables in it, and any one of them might be undefined? 19:44
you are currently getting an "use of uninitialized value in string context" error?
xinming Yea 19:45
Use of uninitialized value element of type Any in string context
I want to die with the variable name, So I can dump context to see what happened 19:46
timo ok not sure how exactly to get the variable name, but you can put `CONTROL { die "dieing because of this warning: $_" };` in front 19:47
ugexe doesn't have to be in front 19:48
xinming Thanks for the CONTROL phaser 19:49
Will try
timo CONTROL runs when any warning is emitted in the dynamic context of your function, which may be more than you want 19:51
also not just warnings are control exceptions
you may want to match on the type in $_ being CX::Warn

antononcube I am making a Doomsday Clock, in Raku. 22:39
But, the clock gauges can be utilized for showing, say, the times at different capitals. I want to also indicate with the color of the clock-faces is it night or day. 22:41
