| .vushu | Hey <ab5tract> I have added macos support if you will like to try also fixed the int pointer bindings for raylib-raku. | 20:39 | |

| habere-et-disper | How do I conditionally load a module? | 21:13 | |
| m: my $debug = True; use Grammar::Tracer if $debug; | |||
| camelia | ===SORRY!=== Error while compiling <tmp> Could not find Grammar::Tracer in: /home/camelia/.raku /home/camelia/rakudo-m-inst-1/share/perl6/site /home/camelia/rakudo-m-inst-1/share/perl6/vendor /home/camelia/rakudo-m-inst… |
||
| habere-et-disper | This give me `Missing semicolon` before the `if`. | 21:15 | |
| librasteve | require is the run time word for use | 21:17 | |
| m: my $debug = True; require Grammar::Tracer if $debug; | 21:18 | ||
| Raku eval | Exit code: 1 ===SORRY!=== lang-call cannot invoke object of type 'VMNull' belonging to no language | ||
| habere-et-disper | Merci encore @librasteve -- I've never used that keyword before. :) | ||
| librasteve | not sure that if can be conditionalized .... I get the same error on my local Terminal | 21:24 | |
| use if; | 21:27 | ||
| github.com/raku-community-modules/if | 21:28 | ||
| use if; # activate the :if adverb on use statements use Grammar::Tracer:if($debug); | |||
| zef install if | 21:29 | ||
| habere-et-disper | That bombed without a line number with `===SORRY!=== | 21:58 | |
| Cannot resolve caller infix:<==>(Mu:U, Bool:D); none of these signatures matches` | |||
| librasteve | works for me | 21:59 | |
| did zef install if work OK? | 22:00 | ||
| if so does use if; load ok (ie. comment out the use Grammar::Tracer line)?? | 22:01 | ||
| how about use Grammar::Tracer:if(True); | |||
| habere-et-disper | yes, yes and yes | 22:02 | |
| librasteve | constant $debug = 1; may be needed as the use is done at compile time | 22:05 | |
| habere-et-disper | Seems a bit bonkers if I can't pass a value in: | 22:08 | |
| `sub MAIN ( Bool :$debug = True, *@files ) { | |||
| use if; | |||
| use Grammar::Tracer:if( $debug ); | |||
| ` | |||
| librasteve | The if distribution will let you conditionally load a distribution. Use cases (no pun intended) are about loading different implementations of a functionality for different operating systems, compiler backends, or compiler versions. This means that these switches for different implementations do not happen at runtime, but cheaply at compile time. This also means that a custom build and install hook is not | 22:16 | |
| needed because all implementations are installed. Then depending on the conditions only the desired implementation will be used. Even if the switch is by backends you can share one installation by several backends using this technique. | |||
| ^^^ this is from the README | |||
| so not bonkers, I guess - but no what you want | 22:18 | ||
| habere-et-disper | `slurp` documentation say that encoding values are listed in method open, but I must be blind because I see none there. | 22:19 | |

| habere-et-disper | docs.raku.org/routine/slurp#type/I...ineroutine | 22:19 | |
| I'm looking for `ISO-8859` but I think I read somewhere it's just best to run it through `iconv` first and give raku utf8. | 22:21 | ||
| librasteve | just to be clear, the use statement is done by the compiler at compile time, then the program is run which is when the variables are initialized and so on - this is pretty normal behaviour, right? | 22:29 | |
| constant gets around this because it's basically a term declaration that statically translates values at compile time | 22:33 | ||
| nemokosch | Yes, good point. This is a compile time option, that's why it needs custom implementation to begin with | ||
| For plain runtime resolution, there is require | 22:34 | ||
| librasteve | yeah, I tried require but at least in the case of Grammar::Tracer it does not work | 22:39 | |
| nemokosch | That could still be a bug or limitation of that particular module, i wouldn't know | 22:40 | |
| librasteve | looking at the module source its a Slang mixin so I expect that it's a fundamental limitation of the Slang model (on similar lines to the documented limitations of require like The symbols provided by the loaded module will not be imported into the current scope.) | 22:43 | |
