<div>Beware, down this path lay demons!</div><div><br></div>One of the problems with language-to-language conversions (unless the languages are already very similar, which these 2 are decidedly not =) is the complete loss of idioms in the language you convert to. You *CAN* convert them of course, but they generally are, as mentioned below, almost totally unmaintainable if even readable at all. I've been at companies that did these sorts of things in the past and they get you over an initial "hump" usually, but in the end any such code that had to be looked at later was always rewritten from scratch. Some code of course never IS looked at again (standard libraries and such) and can remain, but after the institutional knowledge of it has faded, that code has a momentum of opacity too, and sometimes remains even when it SHOULD be looked at and modified.<div>

<br>
Is there a way to convert LISP source code into readable C source code?<br>

Terry posted the following question and I just happened to get asked the same question today. Here is the answer:<br>
<br>
Yes sort of. It can be converted to human readable form but it may not be very maintainable.<br>
<br>
convert lisp to c - I really didn't expect this search to work but it did.<br>

Subject: [4-1a] Lisp to C translators<br>
<br>
Lisp-to-C Translator translates Common Lisp into human-readable ANSI<br>
C. Release 3.2 supports such features as CLOS, the condition system,<br>
Lisp type declaration heeding, and Mac, Windows, and Alpha<br>
compatibility. (Release 3.0, introduced in 1992, eliminated the old<br>
requirement that the garbage collector had to be called explicitly).<br>
Works with Lucid, Symbolics, Allegro, Harlequin and MCL. It costs<br>
$11,995. Write to: Chestnut Software, Inc., 2 Park Plaza, Suite 205,<br>
