I’ve been using a lot more hacklang at work and as such have run into a lot of use cases that don’t seem to have too much documentation. One such use case is how to get the number of keys in a dict.
The hacklang standard library is actualy pretty uniform so similar to other Traversable’s you might be trying to get the count of, you can get the count of keys in a dict with
$my_dict = dict[ 'a' => 1, 'b' =>2 ]; $my_count = C\count($my_dict);
Hi I'm Hamilton and I wrote / built this! I like doing lots of things, but mostly I like to build (and then share those buildings). Some things I'm currently building: art, software, and prose. To stay up-to-date with my latest buildings, subscribe to my email list or follow one of my many other accounts. #buildit #shipit #justhamit
