<trapped> can you raise a compile-time warning rather than error (macro raise) inside a macro?

<PragTob> hello xdougx
<xdougx> may i ask a question about Logger class?
barosl has quit [Read error: Connection reset by peer]
<jhass> don't ask to ask, just ask ;)
gamemanj has joined #crystal-lang
<xdougx> to start the Logger class is needed to pass a File.new? im trying Logger.new(File.open("./log/development.log", "a+")) but when i call log.info("some log") is not writing on the file
<jhass> I don't remember but it probably doesn't flush right away
<jhass> try you can try setting .sync = true on the IO (File, not Logger)
<xdougx> let me check it
<xdougx> keet not writing on the file
<xdougx> keep*
<xdougx> also im on the last version of crystal
<xdougx> is need to logger.close?
<jhass> as in lastest release or compiled from latest development version
<xdougx> needed*
<jhass> well, it should happen automatically on exit I think
<jhass> let me try

BlaXpirit has joined #crystal-lang
<xdougx> that level
<jhass> xdougx: you set the log level to warn and then log info
<xdougx> level is feltering
<jhass> yes, of course it is
<xdougx> filtering*
<jhass> that's its purpose
<jhass> fatal, error, warn, info, debug
<jhass> 1 2 3 4 5
<jhass> only levels lower or equal will be logged
<xdougx> i think I thought putting WARN would warn, info and debug be available
<jhass> and how would you hide info and debug then?
<xdougx> but now i know is the opposite
<xdougx> now it is just fine :) thank you

<jhass> I'm not sure what you're asking exactly
<jhass> there's no build tool written in Crystal yet as far as I'm aware. Most seem to use make
<jhass> well, most that use one at all
<xdougx> like ruby, im thinking to build some tasks to help when i build a project, run some services or generate files templates.
shama has joined #crystal-lang
<jhass> nothing prevents you from using rake or any other existing tool
<xdougx> i see, is a possibility
<BlaXpirit> i never got the point of "make"

<asterite> jhass: didn't change as far as I know
<jhass> well, artanis no longer works
<jhass> maybe the context in which the macro is executed changed?
<jhass> mmh, didn't something about when inherited runs change?
<jhass> I think that's it
<jhass> any idea for a workaround?

<asterite> :foo is a symbol
<BlaXpirit> foo: is not a symbol
<asterite> and `foo: bar` is a named argument
<asterite> `foo : Int` is a restriction
<asterite> That's the reason, sorry
<BlaXpirit> it doesn't even matter that it's a symbol, all these things can still be parsed
<asterite> Yes, but for a human it's better if things are visually consistent, and when you see `foo : T` and `foo: T` you can quickly see the meaning
<asterite> BlaXpirit: or you can see it this way, we never intended `def foo(x: Int32)` to be valid syntax, then we realized the mistake and fixed it... maybe a bit too late, but a regex could fix this very easily
<BlaXpirit> asterite, applying a regex to all files is not as easy
<BlaXpirit> well actually it is but first i wanna ensure it's correct
<jhass> git diff and git checkout to the rescue
<agargiulo> and git stash

<asterite> Well, actually, we should have made the formatter apply that change and later introduce the breaking change... but the formatter appeared after that change, so that wasn't a good choice, you are right. But now it's a bit too late
<asterite> One think you can do, or I can do it if you want, is to change that rule in the compiler, create a compiler and then run the formatter so it does that for you
<asterite> I'll do it and give you the patch (can you compile the compiler on your machine?)
<BlaXpirit> asterite, oh thanks, but don't bother
<BlaXpirit> im just sitting here with (def [^ ]+\(.+\b): ([A-Z])
<asterite> Ah, ok :)
<BlaXpirit> hm i sure skipped a lot of commas in multiline arrays
<BlaXpirit> was removal of this intentional?
tomchapin has quit [Quit: My Mac has gone to sleep. ZZZzzz…]
<BlaXpirit> also i'm pretty sure a: B is still allowed in: lib-fun, struct
<asterite> The skipping of commas is a bug I found, I was surprised to find that too
<BlaXpirit> i thought it was a nice feature :|
<BlaXpirit> some languages have that
<jhass> mmh
<jhass> >> "foo" "bar"
