What is the difference between crystal deps and shards install?
Johannes Müller
@straight-shoota
crystal deps calls shards install, shards install does not :smirk:
From IRC (bridge bot)
@FromIRC
<oprypin> @kazzkiq, shards install is a newer development. crystal deps used to be something else, became a redirect to shards install

I have a NamedTuple that may or may not have some of its keys, how do I create such "dynamic" NamedTuple?
I'm trying something like that, without success:
data = NamedTuple.new(name: String, nickname: String)

data[:name] = name.to_s if name #only assign if name exists
data[:nickname] = nickname.to_s if nickname #only assign if nickname exists
From IRC (bridge bot)
@FromIRC
<Papierkorb> In best case, not at all
<Papierkorb> NamedTuple are immutable data structures, with keys known at compile-time.
<Papierkorb> If you need something mutable, use a Hash
Claudio Holanda
@kazzkiq
Hmmmm, will try that.

Hello everyone, I'm a little curious about crystal, as far as I know it's a compiled language but I'm wondering if it's possible to use Crystal as a script language in say making video games?

<tosmi> hi, i'm trying to compile crystal on freebsd 10.3
<tosmi> following the comment in crystal-lang/crystal#4185, i'm using the 0.19 freebsd binary to build 0.20.0
<tosmi> gmake works, but call gmake spec or running gmake a second time yields the following error message
<tosmi> any hints what i'm donig wrong here? thanks
Bar Hofesh
@bararchy
@piperun there are more then a few people doing game development in Crystal , I don't really understand the Script part in the question though
Johannes Müller
@straight-shoota
I think @piperun want's to use Crystal as an interpreted language to easily allow custom modifications.
This would be very difficult and probably not really helpful, because Crystal's type inference for example needs to assess the whole program and not just parts of it.
Johannes Müller
@straight-shoota
@tosmi I don't know if it helps, but does src/lib_c/x86_64-portbld-freebsd/c/dlfcn.cr exist?
Oh I see you figured that^^
piperun
@piperun
@straight-shoota I see, thanks for the input!
Johannes Müller
@straight-shoota
you could probably better use Lua (or somthing similar, maybe mruby). This language was explicitly designed for such tasks. IIRC there are Crystal bindings for liblua.

@FromIRC
<tosmi> got 0.20.0 to compile after renaming lib_c/x86_64-portbld-freebsd to lib_c/x86_64-unknown-freebsd
<tosmi> but now 0.20.1 fails with in src/compiler/crystal/compiler.cr:155: undefined method 'merge!' for Set(String) (did you mean 'merge'?)
<tosmi> any hints?

@akzhan
@tosmi to to use usual crystal cpmiler with cross-compile to x86_64-unknown-freebsd triple
From IRC (bridge bot)
@FromIRC
<tosmi> with changing the dir (creating a link) it failed with https://gist.github.com/tosmi/5d48acecece6e2e581b8267fc2141a94
<tosmi> ^with^without
Akzhan Abdulin
@akzhan
Strange. dlfcn should be found in triple files (add_target_path responds to this behavior).
Anyway you should upgrade your crystal o 0.22.x at least
From IRC (bridge bot)
@FromIRC
<tosmi> the thing is i try to get the latest version compiled, but i have to start with 0.19, that was the latest release providing freebsd binaries
<tosmi> but it seems i'm too stupid for this
<tosmi> compiling 0.20.0 with 0.19 worked (after fixing the dir) but compiling 0.20.1 with 0.20.0 failed with the merge error message
Akzhan Abdulin
@akzhan
can you cross compile crystal on another platform to yours one?
From IRC (bridge bot)
@FromIRC
<tosmi> ok, i could try that as well
<tosmi> but it seems my problem is related with the crystal standard library
<tosmi> maybe there's no merge! for Set(string) in 0.20.0 but 0.20.1 uses this
<tosmi> so how do i compile crystal 0.20.1 with 0.20.0?
Akzhan Abdulin
@akzhan
it looks like you got wrong source code: 0.20.1 stdlib introduces merge! method
Johannes Müller
@straight-shoota
but you should be able to compile 0.20.1 with 0.20.0
From IRC (bridge bot)
@FromIRC
<tosmi> i'm using bash here and after compiling 0.20.0 i did a export PATH=.../crystal-0.20.0/bin and tried to compile 0.20.1
<tosmi> seems to be wrong...
<tosmi> so my workflow is setting the path, changing to the new crystal version and running gmake
Johannes Müller
@straight-shoota
I guess you could just keep everything in the same directory... make builds compiler into .build/crystal, then checkout next release and make uses .build/crystal from previous build
From IRC (bridge bot)
@FromIRC
<tosmi> @straight-shoota: thanks! looks like that's the issue here. i will try that a little bit later
