00:24 <FromGitter> <Blacksmoke16> idk what im looking at

00:40 <FromGitter> <gregoryc> OK, I got things working well

00:40 <FromGitter> <gregoryc> a@a:~$ crystal code 'cat {sc|{sc|{sc|dog}}} cat' '{.*' } ⏎ ⏎ cat {sc|{sc|{sc|dog}}} cat ⏎ ⏎ cat [ ] cat ... [https://gitter.im/crystal-lang/crystal?at=629ff015c9382316a6435177]

00:41 <FromGitter> <gregoryc> https://carc.in/#/r/da58

00:41 <FromGitter> <gregoryc> Public domain is the license

00:41 <FromGitter> <Blacksmoke16> you can wrap code in three backticks, make it easier to read

00:41 <FromGitter> <gregoryc> Where? Here?

00:41 <FromGitter> <Blacksmoke16> yes

00:41 <FromGitter> <gregoryc> '''

00:42 <FromGitter> <gregoryc> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=629ff05bc9382316a64351f0]

00:42 <FromGitter> <gregoryc> oh wow

00:42 <FromGitter> <gregoryc> I got it working

00:42 <FromGitter> <gregoryc> But idk if there is a nicer solution

00:42 <FromGitter> <gregoryc> Re macros

00:42 <FromGitter> <Blacksmoke16> yea that code is totally unreadable on here

00:42 <FromGitter> <Blacksmoke16> backticks werent done right :S

00:43 <FromGitter> <Blacksmoke16> has to be on its own line, but for larger snippets a gist or playground link is better

00:43 <FromGitter> <gregoryc> I'll try again, sorry, lol

00:44 <FromGitter> <Blacksmoke16> i wouldnt bother, not worth pasting again

00:45 <FromGitter> <gregoryc> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=629ff117deea5616bbe80f1f]

00:45 <FromGitter> <gregoryc> Yeah, it's nice

00:45 <FromGitter> <Blacksmoke16> but whats that code do?

00:46 <FromGitter> <gregoryc> It's a recursive gsub that is generic. Argument 1 is a string, argument 2 is the beginning section (which gets removed), argument 3 is the ending section (which gets removed). The function yields to a block, and the new value is the block's value, surrounded by spaces

00:46 <FromGitter> <gregoryc> Works for string and regexs so far, can be extended easily to other data types

00:47 <FromGitter> <gregoryc> crystal code 'cat {sc|{sc|{sc|dog}}} cat' '{.*' } ⏎ ⏎ cat {sc|{sc|{sc|dog}}} cat ⏎ ⏎ cat [ ] cat [https://gitter.im/crystal-lang/crystal?at=629ff18bdeea5616bbe80fd7]

00:47 <FromGitter> <gregoryc> That is string and regexp

00:47 <FromGitter> <gregoryc> Showing how the values can differ. It's not the best for the string because it doesn't match of course

00:48 <FromGitter> <gregoryc> crystal code 'cat {sc|{sc|{sc|dog}}} cat' '{' } ⏎ ⏎ cat [ sc|[ sc|[ sc|dog ] ] ] cat ⏎ ⏎ cat [ sc|[ sc|[ sc|dog ] ] ] cat [https://gitter.im/crystal-lang/crystal?at=629ff1c809eea00aded31795]

00:48 <FromGitter> <Blacksmoke16> mmk

00:49 <FromGitter> <gregoryc> It's a little awkward because I have to use macro conditionals to make it work.

00:49 <FromGitter> <gregoryc> Is there a better way ? :)

00:49 <FromGitter> <Blacksmoke16> quite frankly i still dont know what it does/what the use case is so not sure

00:50 <FromGitter> <gregoryc> It could be used to parse a lot of things, including html and xml

00:50 <FromGitter> <gregoryc> It's very very useful, because it yields

00:50 <FromGitter> <gregoryc> Just as gsub is useful

00:54 <FromGitter> <gregoryc> Can be used to get rid of unwanted markup

00:54 <FromGitter> <gregoryc> Or extended to do something else

04:26 <wmoxam> Hey, this isn't strictly a crystal question, but I'm looking to recursively render a template in ECR (in order to display a tree). Anyone have experience doing this?

04:29 <wmoxam> I've tried something like this: https://gist.github.com/wmoxam/c17f42b09ac646d15f03aabb70eaab79

09:07 <FromGitter> <moe:busyloop.net> blacksmoke is becoming bigger than j.k. rowling

12:17 <FromGitter> <Blacksmoke16> wmoxam you could try that ECR method object to s
