what is the prime use-case of Crystal ? Systems or performant web-apps?
<jiriki->
I hope both
<jiriki->
because one thing I'd like a new programming language to solve is to have one language everywhere

<kulelu88>
javascript?
<BlaXpirit>
kulelu88 pls
<BlaXpirit>
javascript brings nothing good, it's just forced
<jhass>
kulelu88: so far web backend, systems, end user CLI tool & GUI seem to be the largest interest areas, the latter two because some people see a ruby like language with potential easy (binary) distribution
<kulelu88>
I was thinking of making a CLI drop-in tool for servers with Crystal as well
<kulelu88>
GUIs though... Is there a QT or GTK binding?
<kulelu88>
I've wondered though. What do people use for GUIs for linux these days. There doesn't seem to be a dev-friendly + commercial option in the wild
<jiriki->
jhass: does crystalg have pointers and manual mm?
<jiriki->
or planning to anyway?
<jhass>
jiriki-: yes for pointers, if you absolutely need to you can also do manual memory management, but I wouldn't
<jiriki->
well I'm looking for a great language, and sometimes MM is useful
<jhass>
it's not a first class language feature for sure
<jiriki->
like what D can do
<jhass>
kulelu88: mmh, Python I guess, both its gobject and QT bindings are pretty good. On the lower level Vala is strong with the Gtk crowd, but JS is growing there too. C++ is still strong with the Qt crowd
<kulelu88>
I think Crystal falls just below those languages. It gives you lots of power + productivity, which those others don't provide
<kulelu88>
jhass: language-wise, there are options. But the GUI itself. There is only QT and GTK
<jhass>
well, yeah
<jhass>
the Englightment people produce robust stuff, but it doesn't integrate well into other DEs
<strcmp1>
and xlib, xlib is amazing
<kulelu88>
perhaps node-webkit-style desktop apps are the future
<jhass>
kulelu88: and I agree that Crystal has the potential to grow in the sweep spot between classic compiled and fast prototyping dynamic languages
<jiriki->
well to be honest, a great programming language should solve the problem of using two languages in first place
<BlaXpirit>
jiriki-, C interoperability is strong
<kulelu88>
if it can connect to the thousands of man-hours of work put into C libs, it's already winning
<BlaXpirit>
well that's what being done
<jiriki->
hmh yeah
<BlaXpirit>
crystal leverages many C libraries even in its core
<kulelu88>
I'm tempted to use the blueprint of crystal to build my own compiler, just to learn how it was done
<jhass>
note that hand written parsers is not the most popular way to do it these days, most people use parser generators ;)
<kulelu88>
is that step number 1? Parsing text?
<vifino>
BlaXpirit: Hey, could you help me generate jackaudio bindings? I get pycparser.plyparser.ParseError: /usr/include/jack/types.h:26:18: before: jack_uuid_t from crystalize.py.
<BlaXpirit>
vifino, can reproduce, will look into it. not necessarily right now, though
<vifino>
BlaXpirit: Thanks :)
<BlaXpirit>
vifino, look at transport.h
<BlaXpirit>
macro POST_PACKED_STRUCTURE is simply not defined
<BlaXpirit>
(and for gcc it's defined as some compiler hacks)
<vifino>
And how can we fix this/go around the issue?
<jhass>
kulelu88: well yes, getting a representation of the source you can work with (typically an AST) is step 1
<kulelu88>
how does making the jump from compiling in another language to using your own language to compile happen? Or is that a natural progression that is achieved based on breaking your back writing your own language?
<jhass>
well, you start with writing a compiler in another language and develop it far enough so that an implementation of your compiler in the target language can compile itself
<jhass>
so to self host, you essentially write two compilers, though you'll do it when the language is still as basic as possible
<jhass>
and then you add stuff to the self hosted version such that the old iteration can compile the next one
<ozra>
Anyone here knowledgable on compiler internals? I'm trying to implement `for` as a POC to learn the internals a bit. Lexing, Parsing: ok. Rewriting: unsure, because the test (`for val in list\n p val\nend`) fails with "undefined local variable or method 'val' (did you mean 'val'?)" (!!??). The ast debug printed after rewrite looks like it should (
<ozra>
rewritten to list.each do |val|...). Any ideas?
<ozra>
(I know Crystal probably won't accept a PR for 'for in', but I need to parse a DSL to compile in Crystal, so I simply use it as the basis for that compiler)

Hi @ozra, you will need to go down the parser and lexer. @asterite loves parsers :-). Check src/compiler/crystal/syntax/parser.cr . I would see how the if is parsed line 879. Since you want a control sequence with inner statements but without the block.
<bcardiff>
It good to get more people in the internals
<bcardiff>
it's*

speaking of a debugger, do you know what it'd take to get more info into lldb, like the local variables?

Probably learning the metadata format and setting it
<ozra>
@bcardiff, @asterite: Missed your replies, out mowing the lawn... The lexing and parsing (and rewrite) are done and working. I added a `For` node. I rewrite it using the block of the `for` to create a Block node passed to `the_list.each`.
<ozra>
When I `p the_ast_node.to_s` or `dump the_ast_node` it looks like a perfectly correct `list.each do |val|\n p val\nend` - but still I get that error. 'val' is not declared, did you mean 'val'.. Which is .. confusing..
<ozra>
Updated with the test I'm trying to compile with it

ozra: in the parser, are you pushing the for vars in @def_vars
<asterite>
?
<asterite>
Also, for in Ruby is just .each, that's why I think "for" is a bad idea, it never does "each_with_index"
