Re: Is Forth suitable for writing compilers?

Forth-like languages are designed to make it easier to do one-pass
compilation without backtracking etc. By accepting some limitations on
syntax you make the compiler design much simpler, and the people who get
used to your syntax won't mind at all.

I have made a classical two pass assembler with labels from my
Forth assembler. This requires carnal knowledge of a Forth and
some creativity. Then it can be done with dozen definitions
and two dozen lines of comment.


If you want complexities of syntax that Forth doesn't provide, then you
need extra complexities in your compiler design too.

Of course. But it is limited, Forth is surprisingly flexible.
