If function won't have any args, parentheses can be omitted

I don't think I have to explain this.
Example:

if a > b
   // Do something
elif b < a
   // Do something
else
   // Do something
end

This issue was generated by todo based on a TODO comment in 7a2b674. It's been assigned to @noituri because they committed the code.

Example:

import "<module>"

Example:

let x: str = "That's a string"

" can be used to create string

Basic syntax for arrays:

x: Arr<Type> = [t1, t2, t3]
x[0] = t4
x.append(t5)

Infinite loop:

while(true) equivalent:

loop true
   // do something
end

for x in array equivalent:

loop i, v in array
   // do something
end

Float number can have couple dots. What I mean by that is float can look like that 3.20.1 which is incorrect

this will allow the user to define it's own unary or binary operator (for example Str == Str etc. It will be very useful in libstd)

Atom is a type and value at the same time
Example:

x := :atom 
if x == :another_atom

end

return keyword does not work at the moment (there is no codgen, parser & ast support for return, only lexer has implemented return token)

Highlight expectolang *.exp

Here's example from Rust:

fn do_something() -> i32 {
   if true {
      return 0;
  } else {
     return 1;
  }

   // every case is handled so I don't have to put return here
  // return 2
}

I want to add the same thing in ExpectoLang

Make CLI for compiling purposes
List of commands:

• expecto build
• expecto build --emit-llvm
• expecto run
• expecto version

So classes will probably change but for now it will probably look like that:

class Example
   let mut val: int
   fc init(x: int)
      val = x
   end
   fc print()
      writeln(val)
   end
end

let example: Example = Example(2)
example.print()

Add garbage collector

Escaping strings does not word very well. What if mean by that is GoLang by default when it reads str it does escape "\n" so it's not really new line, also llvm is escaping "\n"

https://github.com/Noituri/ExpectoLang/blob/9cfd1a49135f45939a5382d4be04952fff3aae8c/grammar.md#L7-L12

Basic int support has been added here b51c97e

Example:

// global
fc add(a: int, b: int): int
   return a + b
end

// private
fc _add(a: int, b: int): int
   return a + b
end

compiler should show how much time did it take to build the project

As for now external functions look like that:

@printf(x)

it should look like that:

@printf(x: str): int

Add LLVM Optimizations

This functions simply print data in your terminal.

As for now # is used to comment code but I'd like to use // for single line comment and /* */ for multiline comments

boolean type

Example:

let x: bool = false
let y: bool = true

If I try to use 3 + 1 everything works just fine but If I add third number (or more) it starts to break expression, so 3 + 1 + 4 does not work. 4 is parsed as next expression

At the moment when you'll make syntax error you'll probably get arbitrary error that won't tell you a thing how to fix your problem

Every ast has position (current character) and as for now not every position is valid for given AST, also position should not only consist of current character but also current line

https://github.com/Noituri/ExpectoLang/blob/f8d077b2fe569ad700c9e5964384aca865e038b6/codegen.go#L309-L314

Variables by default are not mutable.
They can be redefined.
As for now they won't detect type dynamically (but it will be added)

Example:

let x: int  = 4

// variable redefinition
let x: float = 3.0

// probably syntax for mutable variables
let mut x: bool = true

Or

x: int = 4
x := 5.0
x: mut float = 1.23
x = 2.0

y: bool

Indexing has not been tested in the loops

So @ will be keyword for calling extern functions
