@didactic-drunk that complete functionality doesn't exist so far as I am aware, but all of the building blocks exist. Maybe it can be my macro-hacking project of the week to build it.
Right now I am picturing something such as simple as include CallTrace, followed by an annotation on top of any method that one want's to build a call tracing stack for.
The actual call trace would be accessible at any time.
hello guys... this code pings out on Rizon (Ping Timeout) after it joins the #8chan channel... I asked in #Help on Rizon but I'll post the code here in case anyone wants to try to find the issue.... it has to do with the level of chatting... I suspect I need a "spawn" somewhere. https://gist.github.com/mixflame/e4bc13dd5d9a73af1524b2fe52c430a6
note that rizon is a custom network with special requirements that other networks don't possess.... like pinging on connect... might look wrong for other networks or just be fine... not sure about IRC internals as much as others might be
if you want to use it to build a bot, go ahead, it's based on the irc lib for crystal on github
be aware of the ping issue and if you find a solution let me know
Thank you
I feel like mine should still work though
Or am I misunderstanding something?

Also as a side note, I feel like we shouldn't need to include
A as one of the branches of the case since it cannot have an instantiation at runtime
If I wanted to check the runtime type of an object in my example there, but I defined === on A, how would I go about doing that? Or would I just have to use a conditional expression to check the class?
I'm just wondering
it might just work tbh, like see the the
when value is a type as the compiler expands it to is_a?
be easy enough to try
Only other thing then would be that this should technically be able to compile I believe, since foo.is_a? cannot be an A, right? https://carc.in/#/r/bc45
since its a parent to both
hi there! former rubyist and crystal newbee here. I am currently writing some crystal code and wanted to use the mixin Enumerable on class level rather than on instance level (see code below). any hints?

Hi, any suggestions on how I would best implement a predefined set of format strings / placeholders that can be user-specified (e.g. via config file)? I don't want allow users to directly influence the
#sprintf formatstring for security reasons, I was thinking more in the direction of having something like "some prefix: ###foo.attr1### with ###foo.attr2###" where I want to replace "###foo.attr1###" with the value of foo.attr1 and so on. How could achieve that somewhat elegantly?
@foxxx0 Crystal doesn't support RTTI, that means there is no way to achieve dynamic execution of props/methods. Crystal expects methods/fields calls to be known at compile time. What I understand from your context is you are looking for some template language which you can invoke at run-time

maybe i'll need to parse the user-supplied argument then and provide crinja with the correct value? but then there is no point to pulling in crinja
Template engine doesn't force you to any specific set of usage
you can access any object as long as template engine has access to that object
For example
{%- for article in articles if article.published %}
<div class="article">
<h2><a href="{{ article.href|e }}">{{ article.title|e }}</a></h2>
<p class="meta">written by <a href="{{ article.user.href|e
}}">{{ article.user.username|e }}</a> on {{ article.pub_date|dateformat }}</p>
<div class="text">{{ article.body }}</div>
</div>
{%- endfor %}
