super calls the inherited function.

eg.

class A
  def self.foo()
    foo()
  end
end

Does not compile without these lines.

Parse if like this.

if foo
  bar
  baz
end

Currently 2 * 2.0 raises error but it is not convenient.

eg.

class A
  def initialize
    var @a = 1
  end
end

A = 1
class B
  def foo; A; end
end

Error: Error { msg: "constant `ConstFullname("::A")' was not found", backtrace: stack backtrace:

eg. this does not work

if 1 != 2
  puts "ok"
end

With Int#to_s and String#+, we can write this.

size = 600
puts "P4"
puts size.to_s + " " + size.to_s

code_gen/mod.rs is expected to get longer and longer.

Now it is a good time to extract gen_methods into another file.

eg.

class Base
  def initialize
    @a = 1
  end
end
class Sub : Base
  def foo -> Int
    @a
  end
end

Currently it is parse error

Current @main contains both system code and user program. Extract the latter as a function for better readability of .ll.

foo= should take only one argument.

Currently the parser supports &&, || but hir and code_gen does not.

cargo run -- run examples/hello.sk
Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }

full path not working too.

list files:
hello.sk
hello.sk.ll
hello.sk.opt.ll

2. cp shiika hello.sk /tmp && cd /tmp && ./shiika hello.sk # not working too

At first I'm planning to use Void as void literal. However I found this conflicts of Void class object.

How about adding void pseudo variable like true and false?

shiika run ray.sk fails when IMAGE_WIDTH, IMAGE_HEIGHT is big (like 1000x1000).

https://github.com/ruby/ruby/blob/master/benchmark/so_mandelbrot.rb

Found that this raises error.

class Base
  def initialize(i: Int)
    @a = i
    putd @a  #=> "ivar `@a\' was not found"
  end
end

It is nice if we could write tests in Shiika, not in Rust.

Current user_main has constant initialization in addition to "real" user main. Extract them as a llvm func (like init_const or so)

Currently Lexer does not distinguish ; from newline, but there is a case where newline is allowed but semicolon is not.

Example:

# OK
foo(1,
2)
# NG
foo(1,;2)

eg. 3.0 % 2 results in

Error: Error { msg: "method MethodFirstname("%") not found on ClassFullname("Float")", backtrace: 0: backtrace::backtrace::libunwind::trace

eg.

class A; end
class B : A; end

Given this, define #a, #b and #b= automatically

class A
  def initialize
    @a = 1
    var @b = 2
  end
end

eg.

class Base
  A = 1
end
class Sub : Base
  def foo
    puts A  #=> 1
  end
end

eg.

A = 1
A = 2  # should be error

Not that this is legal:

if foo
  A = 1
else
  A = 2
end

Successor of #84

• #104 [1,2] should be inferred as Array<Int>
• #108 Fix codegen for [1,2]
  • Array<Int>.new should be exist we can just call Array<T>.new instead.
• #109 Extend SkClass to have (0 or more) type parameters
• #109 Support type parameter on class definition
• #112 Support type parameter on method return value
• #112 impl. Array#first
• #116 [1].first should be inferred as Int

Got ParseError with this

x = 0
1 + (x * 2)

Or just:

i = 2
(i * 3)

Long way to go...

Especially, code gen of Float/Int/Bool needs to be reconsidered to support Array<Object>.

• #85 parser
• #85 generic type
• #91 change Float to llvm struct
• #92 embed Int into pointer or make it llvm struct
• #95 embed Bool into pointer or make it llvm struct
• #97 codegen for array literal ([Object.new])
• #100 codegen for non-Object item ([1,2,3])
  • cast is needed (Int -> Object)

Fix duplicated code of them

Error: Error { msg: "expected separator but got Equal", backtrace: stack backtrace:

eg.

class A
end
A.new  #=> should not raise error

Note: Shiika will not support unless-else (in contrast to Ruby).

Current test passes even when no code is successfully executed.
Should add puts "ok" or something and check it.

Try compiling 7cf106d

https://mapping-high-level-constructs-to-llvm-ir.readthedocs.io/en/latest/appendix-a-how-to-implement-a-string-type-in-llvm/index.html

In Ruby, "stdlib" refers classes that loaded by explicit require and "corelib" means classes do not need require.

I heard there's a technique to accept both &str and String as an argument. With this we can avoid unneeded .to_string()s.

So that they can be displayed with {} in format!

eg.

class A
  class B
  end
end
b = A::B.new

eg. puts "ok" if x == y

Since #23, the line number in error report includes corelib 😭
