Do you some sample code available?

It's nice to see there is so much Forth related activity here. I've posted some code for a macro-processing text filter that I'm using as an alternative to Unix's m4 in some personal projects. Although it's written in c, it's Forth-like enough that it might be of interest to some here. https://github.com/rdrop-exit/backtick-macro-processor Cheers — You are receiving this because you are subscribed to this thread.

There are a few examples in the documentation draft: https://rdrop-exit.github.io/backtick-macro-processor/

Much of the macro processor itself is implemented as macros, the source for which can be found in
the backtick.mac file in the repository.

Here's an example that prints out the 99 bottles of beer song :-)

`'this-many-bottles  ( n -- n )
 `{`dup`dec`[[no more bottles]]`[[1 bottle]]`[[`dup`print bottles]]`ifa}  `new

`'one-less-bottles  ( n -- n-1 ) `{`dec`this-many-bottles}  `new

`stdout`
`99`{`
`this-many-bottles of beer on the wall, `this-many-bottles of beer.
Take one down and pass it around, `one-less-bottles of beer on the wall.

}`over`times`
No more bottles of beer on the wall, no more bottles of beer.
Go to the store and buy some more, 99 bottles of beer on the wall.
