deoac Can a Raku program determine whether it was started from the command line vs. a cronjob? 00:26
rf I think you can check if you're in a TTY 00:45
tea3po say $*IN.t ?? "Input comes from tty." !! "Input doesn't come from tty."; 00:47
idk how to detect if something is running under cron specifically 00:49
rf you could set an env variable in your cron script 00:50
IS_CRON=yes raku myscript.raku
habere-et-disper $*USER might be CRON ? 00:52
tea3po I imagine it would be root for system crontab, the user for user crontabs. 00:54
deoac Thanks all.  I'll check both $*IN and $*USER. 00:55
00:56 Manifest0 left
deoac $*USER is my username when run as a cronjob. 00:58

pelevesque Anyone know how to check if a class exists in the given namespace? 04:48
04:51 tea3po is now known as TEATIME
Nahita NS::{$class-name}:exists maybe 05:19
if it's a my-scoped class it won't be seen though 05:20
with this code
pelevesque did not work... says exists is not set 05:41
05:42 TEATIME is now known as teatime2, teatime2 is now known as teatime
Nahita m: module NS { class A {} class B {} } for ("A", "B", "D") -> $class-name { ($class-name, NS::{$class-name}:exists).say } 05:46
Raku eval (A True) (B True) (D False)
pelevesque I import a module use MIDI::Make; And then I want to test if the File class from that module was made available. 05:49
Nahita in "Make.rakumod", what do you have? 05:55
like do you have "unit module Make;" (or "module Make { ... })
and "class File" only 05:56
or "class File is export"
if it's like module Make { class File { } } (or with "unit module Make;") then in the file that's "use"ing this, Make::<File>::exists says True 05:57
but if it's "my"-scoped (the class) and only "is export", then ::<File>:exists can tell whether it's imported to the current space 06:00
if it's both "our"-scoped (i.e., the default) and "is export", then both of them can tell
pelevesque Yes, Make.rakumod with unit module make 06:02
class File is export(:shortnames) {}
thanks! 06:03
Nahita no problem

Sussysham hi 16:12

Sussysham lizmat Greetings senpai 16:13
I mean senior
lizmat domo arigato
if you go by years, I guess you can call me a senior :-) 16:14
but I'd rather like to think of the "teacher" connotation :-) 16:15
Sussysham I will also prefer that
can you help me  with setup?
lizmat of Comma? no, I'm afraid I'm a vim person 16:19
Sussysham youtu.be/zDP9uUMYrvs intersting 16:20
lizmat No worries sensei I will figure something out
btw nxadm seems  ofline  username doesn't show up on @ 16:21

pelevesque Does anyone know what the api key refers to in the META6.json file? 16:48
16:50 Sussysham joined
Sussysham lizmat 16:51
lizmat pelevesque the api key means what you want it to mean: 16:52
it provides a way for users to specify which API version they want when installing / loading a module
by default it is 0 afaik
pelevesque By that API refers to the module itself, or the API or Raku? If for the module, isn't the version number enough to know what is implemented? 16:58
lizmat the API of the module itself 17:02
it's up to the module author what that actually means
use Foo:api<2>;
would load the Foo module with api 2 (if installed of course)
zef install 'Foo:api<2>'
would install the highest version Foo module with api 2 (if such a thing exists, of course) 17:03
pelevesque Is it required?
dakkar pelevesque: if the author is doing the whole semver thing, api and the major version would be more-or-less the same 17:04
and no, it's not required
pelevesque OK thanks. Ya, I am using semsev 2. I will drop my API key.
17:05 Sussysham left
dakkar keep in mind that there's no simple way for code to ask "give me the latest version that's >= 2.0.0 and < 3.0.0" 17:05
but there is a simple way to ask "give me the latest version that's api==2"
so if you think you will have a version 2.0.0, 3.0.0, &c, you may want to start with `api=>1` 17:06
if you end up not needing it, no harm done
Nemokosch doesn't e.g 2.* give you the latest version? 17:08
dakkar I'm not sure 17:09
lizmat if you aren't specific, it will give you the highest version, regardless of api 17:10
17:11 Sussysham joined
Nemokosch is this true for all patterns? 17:11
dakkar lizmat: where's the documentation for `use` with a longname? none of docs.raku.org/language/module-packages.html docs.raku.org/language/modules.html docs.raku.org/language/compilation.html 17:13
lizmat please make a doc issue for it :-) 17:14
Sussysham Will i have setup rakudo or raku first to use Comma ide
dakkar rakudo is the implementation, raku is the language
Sussysham What SDK it is asking for?
dakkar (like CPython and Python) 17:15
Sussysham ok
dakkar (but I don't know anything about Comma, sorry)
Sussysham np
lizmat Sussysham: couldn't you just download the standalone version? commaide.com/download
afk& 17:16
Sussysham it is theone 17:17
that i downloaded
when i create new project it says no sdk specified 17:18
sdk is required for compiling debugginng
Nemokosch does comma not have an IRC channel maybe? 17:20
oh btw 17:24
