<FromGitter> <backward-crazy-mage-puppy-36> Hello, How do i compile crystal 1.3 with interpreter ?
<FromGitter> <> @backward-crazy-mage-puppy-36: + The difference being `make interpreter=1` as mentioned here

<FromGitter> <backward-crazy-mage-puppy-36> Thank you @opryin, any idea how to get the interpreter working with an amber project ?

<FromGitter> <> @backward-crazy-mage-puppy-36: there's a huge probability that it wouldn't work. the interpreter isn't in good shape yet, particularly it'd need to load OpenSSL which i think it can't load libraries yet

<FromGitter> <mattrberry> Potentially an odd question. I have a Config class that includes YAML::Serializable. I have a number of properties on that class defined with the property macro. I'd like to make it such that whenever I call the setters for any of those fields, the yaml file is written back. I could write my own property macro that does effectively the same thing or I could just write the setters by hand, but is there a
<FromGitter> ... nicer way to do that?
<FromGitter> <Blacksmoke16> How many properties?
<FromGitter> <Blacksmoke16> An alternative easier way would be to add a save method. Then would write it just once
<FromGitter> <mattrberry> At the moment it's 5, 2 of which are nested YAML::Serializable
<FromGitter> <Blacksmoke16> Otherwise I'd probably just keep it simple and change them to getters and define custom setters
<FromGitter> <mattrberry> Yeah I have a write method that I currently call after writing
<FromGitter> <mattrberry> Just was wondering if there was a simple way to define something like an "after" block on a setter, but I didn't see anything in the api docs
<FromGitter> <> A custom setter is exactly what you need
<FromGitter> <mattrberry> Cool I'll stick with whatever looks nicer between the custom setters and the explicit write method
<FromGitter> <mattrberry> Ty
<FromGitter> <Blacksmoke16> 👍
<FromGitter> <> You can have both though
<FromGitter> <vgramkris> anyone, why is it throwing error for require logger?? ⏎ ram@ram-XPS-13-9310:~/Code/logger_test$ crystal run ⏎ Showing last frame. Use --error-trace for full trace. ⏎ ⏎ In ... []
<FromGitter> <Blacksmoke16> logger was removed in favor of the `Log` module
<FromGitter> <vgramkris> oh, i did not know that, thanks will check it out
<FromGitter> <Blacksmoke16> wonder how bad of an idea it would be to do the write call in like `at_exit` or `finalize`
<FromGitter> <Blacksmoke16> prob very :S
<FromGitter> <Blacksmoke16> 👍
<FromGitter> <mattrberry> That would be fine as long as the program exits gracefully, yeah?
<FromGitter> <mattrberry> Or at least doesn't segfault?
<FromGitter> <Blacksmoke16> not sure, never looked into it too much

<FromGitter> <> is there a way to get the file a macro is being called from?
<FromGitter> <Blacksmoke16> what if you do like
<FromGitter> <Blacksmoke16> `macro foo(maybe_arg, *, file = __FILE__)`
ur5us has joined #crystal-lang
<FromGitter> <> let me check
<FromGitter> <> I dont want the "file" where the macro is defined, but where its being called from
<FromGitter> <Blacksmoke16> did you try it?
<FromGitter> <Blacksmoke16> pretty sure thats what it would do
<FromGitter> <> ill see
