01:44 <CraigBuchek> How can I recompile the compiler?

01:52 <waj> bin/crystal src/compiler/crystal.cr

01:54 <CraigBuchek> waj: That's what I thought, but that's (silently) building a 26K binary that does nothing.

01:56 <waj> so strange… but it compiles any other program just fine?

01:57 <CraigBuchek> Yup.

01:57 <CraigBuchek> Uh-oh. I left off the .cr at the end. It was compiling the directory.

01:57 <waj> :)

01:57 <CraigBuchek> :embarassed:

01:58 <CraigBuchek> Ah, much better.

01:58 <waj> that's a bug anyway

01:58 <CraigBuchek> Well, to be fair, there was a directory with that name.

02:00 <waj> yup, but the compiler should raise a warning

02:01 <CraigBuchek> When I did icr without the .cr it told me.

03:24 <travis-ci> [travis-ci] manastech/crystal#881 (master - 0b9a9fe : Ary Borenszweig): The build has errored.

03:25 <CraigBuchek> Hmm. It says the build errored, but it doesn't appear to have actually run yet.

03:30 <CraigBuchek> Yay!!! My first commit.

03:31 <waj> :D

03:32 <waj> sometimes travis reports as errored but seems like it was still waiting for a server to run the build

03:32 <waj> we're using travis for the macos build and drone.io for linux

03:33 <CraigBuchek> Asterite has been on top of my PRs tonight.

03:34 <waj> yup!

03:34 <waj> btw… I don't know if I'd bother too much about icr. It was just a concept thing but it's actually quite nasty what it does.

03:35 <CraigBuchek> I like to have a REPL once in a while.

03:35 <CraigBuchek> I've got it working; I don't think I'll have much desire to enhance it.

03:35 <waj> sure, for testing small things, but I would not sell that crystal has a repl right now :)

03:35 <CraigBuchek> I see.

03:36 <waj> have a real repl with the full type inference could be quite challenging

03:36 <CraigBuchek> Crystal is still labelled as pre-alpha, so I wouldn't be too worried.

03:36 <CraigBuchek> Yeah. I was actually a bit surprised that there was a REPL at all.

03:37 <waj> it evaluates the whole history every time

03:37 <CraigBuchek> I'm much more inclined to work on making the spec lib more useful.

03:38 <CraigBuchek> I'm impressed so far. Things are fast, done well/right.

03:39 <waj> thanks! :)

03:39 <CraigBuchek> I should be the #3 all-time committer by the end of the week. ;)

03:39 <CraigBuchek> Small commits FTW!

03:40 <waj> absolutely!

03:41 <waj> There are a couple of things that has to be fixed to make the language more fun to use

03:41 <waj> closures for example

03:43 <CraigBuchek> I'm excited about it.

03:44 <CraigBuchek> I'm working on Date classes and writing up a presentation as I go. The first one will be at the local Ruby group in a about 6 weeks.

03:44 <CraigBuchek> Then hopefully RubyConf in November.

03:44 <waj> that will be awesome!!

03:44 <waj> we plan to make a proposal for rubyconf uruguay

03:45 <CraigBuchek> Hey, is the compiler multi-threaded? Because when I run time against it, the clock time is always smaller than the CPU time.

03:47 <waj> yes, the conversion from LLVM bytecode to assembler is done in parallel

03:47 <waj> it generates a llvm module for each class

03:48 <waj> and checks if the bytecode didn't changed from the last run, then it just reuses the assembly file

03:49 <waj> tons of space for improvement there

03:52 <CraigBuchek> I find it to be pretty fast already. But I was guessing there's still room for a lot of performance improvement.

03:53 <waj> when you build the compiler it actually shows some limitations of the current implementation

03:53 <waj> I mean… it takes several seconds to run

03:53 <waj> imagine using it for a real project with much more code

03:54 <waj> ok… got to go now. Have a nice weekend. Keep coding! ;-)
