12:59 <FromGitter> <agibralter> Does anyone have a suggestion on a mocking library to use?

13:15 <BlaXpirit> none if at all possible

13:34 <FromGitter> <agibralter> So basically depend on dependency injection and pass in fakes?

13:44 <FromGitter> <agibralter> Also, what would be a good way for me to handle executing a system command that tails logs (e.g. `\`tail -f some/log.log\``) such that I can handle an interrupt from the user (ctrl-C) and not have crystal error out?

14:56 <FromGitter> <yxhuvud> You can trap the signal. Dunno where to find documentation on that though

15:27 <FromGitter> <firejox> Is there a way to expand the argument of macro like c macro ?

15:38 <FromGitter> <cjgajard> maybe you can try with macro escaping `\{% ` or `\{{`. what do you need it for?

16:11 <FromGitter> <firejox> something like this. I want the inner macro would be expanded. ⏎ https://gist.github.com/firejox/04dee41a4d71e9334ff157b5f4a30b75

16:13 <FromGitter> <agibralter> Ah, I saw that signal trapping: https://github.com/crystal-lang/crystal/issues/1968#issuecomment-167014345. Any idea how to then send a signal to the process I fired up?

16:47 <crystal-gh> crystal/master 0f2933a Sijawusz Pur Rahnama: Ditch code scheduled for removal after 0.19

17:13 <FromGitter> <paulcsmith> Is there a macro hook for injecting code at the *bottom* instead of the top? I'm trying to make it so that if I forgot to check for authorization it fails to compile. Here is a simplified example of what I'm attempting to do: https://gist.github.com/paulcsmith/226ef9a8265875a5d933d7386a029934

17:13 <FromGitter> <fridgerator> came across this article on Hacker News that mentions Crystal FYI : http://patshaughnessy.net/2016/11/26/learning-to-read-x86-assembly-language

17:19 <FromGitter> <sdogruyol> Pat is a great writer

18:27 <rolha> hi everyone

18:28 <rolha> this might sound thick ... but where is the power method in 'Math'? I've tried looking in https://crystal-lang.org/api/0.19.4/Math.html, but I couldn't find it...

18:32 <RX14> rolha, you can use x ** y

18:32 <rolha> duh ... thanks :)

18:32 <rolha> does it support Floats, etc?

18:32 <RX14> yes

18:32 <rolha> brilliant, thanks!

19:48 <FromGitter> <jwoertink> I'm taking a look at the examples for using `String#match` on here https://crystal-lang.org/api/0.20.0/Regex/MatchData.html, but I'm getting `'String#match' is not expected to be invoked with a block` error

19:48 <FromGitter> <jwoertink> https://play.crystal-lang.org/#/r/1etd

19:48 <FromGitter> <jwoertink> Getting this on 0.20.0 as well (even though playground shows 0.19.4)

19:49 <FromGitter> <jwoertink> it looks like none of these methods in the docs work..... or I'm doing something wrong here?

19:54 <FromGitter> <jwoertink> hmm yeah, looks like no block is defined https://github.com/crystal-lang/crystal/blob/master/src/string.cr#L2933

20:58 <FromGitter> <spalladino> > **<mussela>** I mean being able to eval code at runtime ⏎ ⏎ ⏎ @mussela just read this. There's someone building a dynamic language interpreter on top of crystal: https://github.com/KCreate/charly-lang. Though it's marked as not prod-ready, it might be useful for you if you need some sort of scripting language that can run from Crystal. As another option, there are at least 3 implementations of LISP interpreters in

21:09 <FromGitter> <crisward> Does anyone know if it's possible to get a list of files and loop over their names in a macro?

21:15 <FromGitter> <cjgajard> @crisward get a list of files.. from?

21:19 <FromGitter> <spalladino> @crisward you can always call an external program via the `run` macro. You can loop over files in that program, and return whatever you need to be inserted as a macro. https://crystal-lang.org/api/0.20.0/Crystal/Macros.html#run%28filename%2C%2Aargs%29%3AMacroId-instance-method

21:21 <FromGitter> <crisward> @spalladino Thanks - think that's what they're doing here - https://github.com/ysbaddaden/artanis/blob/master/src/render.cr#L20

21:24 <FromGitter> <spalladino> If a system command does the trick for you, then yeah, you can always use https://crystal-lang.org/api/0.20.0/Crystal/Macros.html#%60%28command%29%3AMacroId-instance-method
