That it could be translated into C is obviously true, in two senses.
First it's software for a von Neumann machine, and you can recode any
such software in C. Second, since it is Perl+Libmarpa and Libmarpa and
Perl are both already open-source C, in one sense it is *already* in C.
But I'm not sure what the reader is going to expect if you claim
something "can be translated into C?"
Actually a SLIF-to-C compiler wouldn't be that hard (I think Jean-Damien
has already done major pieces of it.) But that's a discussion I'll move
onto the IRC channel.

Ah, well. I'm reluctant to write the C required to do this myself.
I'm about the announce my almost-finished new parser of Graphviz DOT
files on the [graphviz-interest] mailing list, and wanted to say that
I develop in Perl but that everything can be translated into C.
If no-one's (publicly) done that, I'll have to consider what to say/do.
I confess I did not study the THIF's docs yet.
Someone capable of documenting how to turn SLIF into THIF might be
better off rewriting the upper layers in some other form, such as
pure C or C++, Python, better Perl, etc., etc. I'm doing that, in
C and Lua, as the
When you say ' the upper layers', what exactly did you have in mind?
My Perl or Marpa::R2? From your next comment, I assume the latter.
Kollos project. (I'm overloaded, so Kollos won't happen
quickly.) This is following the principle that, when the code is
not at all clean, you rewrite first and THEN document. It would
also be more fun for the rewriter, because it would allow the
rewriter to experiment with the language/interface of their
choice. (As to why the current XS/Perl implementation is a mess,
the answer is that it evolved incrementally in response to the
demand for new features, and in the face of a strict requirement
that every change had to preserve compatibility, even with
obsolete interfaces.)
I'm not complaining about the (existence) of the XS/Perl interface.
It's fabulous you've made such a thing available, since it makes me
incredibly productive.
And I've never learned XS, so I'm now concerned I'd have to work in XS
in order to work out to talk to the THIF.
Yak-shaving, anyone?
