The Ring language is very interesting to me, it's syntax flexibility means you can modify the keywords and operators of it's syntax before the rest of the code / compilation takes place which allows for the rest of the code that follows to be made to look a lot more like various other programming languages. If you look at the examples on that page I linked to above you will see why I posted about it in the xTalk Implementations section.

Try RING online:

Paste this in to that page and click run to see how the syntax flexibility can modify the language so that it behaves like xTalk for string concatenation:

Code: Select all

ChangeRingKeyword print put
ChangeRingOperator + &
ChangeRingOperator nl cr

PUT "HELLO" & cr & "TEST"

Did you ever go through a Rebol phase? So many great ideas in Sassenrath's tookit.

I have stumbled across it a few times. It looks like it hasn't been updated since 2011, with only an unofficial release in 2014.

The syntax defining bits of syntax are always difficult for my brain to wrap around, not just in Rebol.

Here is the Extension Builder source code for the XB Language Module that contains it's Canvas Drawing syntax:
https://github.com/livecode/livecode/bl ... canvas.lcb
Which is binds LCB syntax to things in the C++ files named: module-canvas.cpp, module-canvas.h, module-canvas-internal.h which are in the same directory.

There's no documentation that I can find on using their syntax defining structure.
But it's still easier to understand than others, at least to me but I already understand the way the FFI bindings work and LCB specific stuff like that so that probably helps.

Ring (one ring to rule them all) makes it super easy to redefine its parser/interpreter for keywords and operators, but not, as far as I can tell, the token ordering.
