objoscript's Issues

Incorrect precedence for the range operator.

var n = 10
System.print(1..n-1)

In the code above, the AST generated is wrong. It is being parsed as (1..n) instead of 1..(n-1)

Add test(s) for the `File` class.

Add syntax for creating key-value literals.

KeyValue is already a core class. Add a way to create these classes quickly with a literal.

ReadLines Function Fails on Files with multiple EndofLines

Say you have a file containing:

The
quick
brown

fox

jumped

over
the
lazy

dog

When looping thru a readlines generated list, as the code current stands, will render:

The
quick
brown
foxjumpedover
the lazydog

when...

The
quick
brown
fox
jumped
over
the
lazy
dog

is expected.

The changes to the function as below, rectify the issue on all instances containing multiple EndofLines.

Thank you!

`Protected Sub ReadLines(vm As ObjoScript.VM)
/// Returns a list where each item is a line in the file.
///
/// FSItem.readLines() -> List

Var file As ObjoScript.Instance = vm.GetSlotValue(0)

// Error checks.
If file.ForeignData = Nil Or FolderItem(file.ForeignData).Exists = False Then
vm.Error("The file does not exist.")
ElseIf FolderItem(file.ForeignData).IsFolder Then
vm.Error("Cannot read lines from a folder.")
ElseIf Not FolderItem(file.ForeignData).IsReadable Then
vm.Error("Cannot read file.")
End If

Var tin As TextInputStream
tin = TextInputStream.Open(file.ForeignData)

Var lines() As String

try
var tContent as String = tin.ReadAll().ReplaceLineEndings(EndOfLine).ReplaceAll(EndOfLine + EndOfLine, EndOfLine)

While tContent.IndexOf(EndOfLine + EndOfLine) <> - 1
  //recursion
  tContent = tContent.ReplaceAll(EndOfLine + EndOfLine, EndOfLine)
wend

lines = tContent.Split(EndOfLine)

Catch e As RuntimeException
vm.Error("An error occurred whilst reading the file: " + e.Message + ".")
Finally
tin.Close
End Try

vm.SetReturn(vm.NewList(lines))

End Sub`

I wrapped the function with code tags, but GitHub fails to 'code' block the entire function

Need to add some sort of `switch` statement.

Multiple nested if...else if statements are not fun. Implement a switch statement.

Add sorting to lists

It would be nifty to be able to sort a list using a function.
