Add JSON Literal​

It is now possible to parse a string via the JSON literal and creating an RocketLang object (array or hash) from it.

🚀 > JSON.parse('{"test": 123}')
=> {"test": 123.0}

🚀 > JSON.parse('["test", 123]')
=> ["test", 123.0]

See JSON for more information.

Support for Single Quotes (')​

You can now use single-quotes to create a string additionally to the already existing double-quotes. This allows more flexibility in creating rich content like json.

'test "string" with doublequotes'

Escape double-quotes in double-quoted string​

Inside a string created with double-quotes " you can escape a single double-quote to create strings more flexible.

"te\"st" == 'te"st'

Removed​

next and break argument​

This version removes the ability in break and next to submit an argument as it did not work reliable and intuitive.

In order to update your program to this version you need to make the following adjustments:

foreach i in 5
  if (i == 2)
    next(i)
  end
  puts(i)
end

foreach i in 5
  if (i == 2)
    break(i)
  end
  puts(i)
end

needs to change to:

foreach i in 5
  if (i == 2)
    next
  end
  puts(i)
end

foreach i in 5
  if (i == 2)
    break
  end
  puts(i)
end

Introduce NIL Object​

Up to this version some functions were returning NULL. Now a proper NIL object has been added which replaces all existing NULLs and is now also createable like every other object by the user.

See NIL for more information.

Removed​

NULL has been replaced by NIL​

As stated above, NIL is replacing NULL.

HTTP builtin added​

The HTTP builtin has been added which allows to create a builtin webserver and handle incoming requests.

See HTTP for more information.

Add Ability to marshal Objects to JSON Strings​

You can now use .to_json() to various objects in order to convert them to their JSON respresentation.

See JSON for more information.

Support for Next and Break​

Within a loop you can now use break and next for complex control flows.

foreach i in 5
  if (i == 2)
    next("next")
  end
  puts(i)
end

foreach i in 5
  if (i == 2)
    break("break")
  end
  puts(i)
end

// Returns

0
1
3
4
0
1
"break"

Allow String Multiplication​

Support for repeating a string by a given number using the * operator has been added.

🚀 > "test" * 2
=> "testtest"

Allow Integer Iteration​

An Integer can now be iterated.

🚀 > foreach i in 5 { puts(i) }
0
1
2
3
4
=> 5

Support for Modulo Operator​

Modulo has been added as valid operator.

🚀 > 5 % 3
=> 1

Support for Ternery Operator​

It is now possible to use the ? operator.

🚀 > 4 > 3 ? true : false
=> true

While Loop​

Support for while has been added.

🚀 > a = 0
🚀 > while (a != 4)
  puts(a)
  a = a + 1
end
// which prints
0
1
2
3
=> nil

Improvements​

Add Shorthand to convert Float to Integer​

The .plz_i() method has been added to the Float object.

🚀 > a = 123.456
=> 123.456
🚀 > a.plz_i()
=> 123

Fix Object Index and add support for Index Range​

The index operator [] has been fixed for many objects and now supports also ranges.

a = [1, 2, 3, 4, 5]
puts(a[2])
puts(a[-2])
puts(a[:2])
puts(a[:-2])
puts(a[2:])
puts(a[-2:])
puts(a[1:-2])

// should output
[1, 2]
[1, 2, 3]
[3, 4, 5]
[4, 5]
[2, 3]
[1, 2, 8, 9, 5]

Return written bytes on FILE.write​

If you write to a file it now returns the written bytes instead of true.
