Normally when you implement a compiler or an interpreter the point is raising the level of abstraction. It makes a lot of sense to implement an assembler writing in machine code, then a C compiler using the assembler, then a Python interpreter using the C compiler Staying on the same level or going in the opposite direction is not nonsense but a lot less natural
Maybe this interests you http: So I think it would be really hard to auto-translate a yacc program into a Lisp program.
Your best bet is to hand-translate the yacc grammar into CL-yacc or what other tools there are. I think C would be far too complex and weird grammar-wise to allow nice hand-written parsers. Is Emacs Lisp inappropriate somehow?
Thanks for this tip - I never heard of the Bovinator before. The documentation and some tutorial material is on my to-do list. However, it is widely acknowledged that parsing C is a rather ugly problem, more work than it is worth. I would suggest you duct tape some existing parser onto your front end and see how Lisp works for the interesting stuff.
If your compiler works really well and you want to make it independently portable, that would be the time to deal with the unpleasant task of parsing.
C Use Zebu http: Zebu is a CL parser generator for CL. D There are sources available for a C compiler written in Zetalisp http: Cliki says it is not trivially portable, but perhaps ripping out the parser and porting it to CL is not as difficult.
I agree with Steven that the parsing is probably the least interesting part of your project, so just find something that works and move on to the interesting things. You can always replace it later. I would appreciate it, however, if you could make sure to credit me as the original author in the documentation of any software that uses these sources.
This is most definitely work in progress; while a variant of this code has successfully parsed a few thousands lines of C, it is known to be incomplete and buggy.
Design and Implemenation" by Fraser and Hanson which describes the lcc compiler. Fraser and Hanson and Davidson invented some blazing compiler-compiler technologies, including the ideas used by GCC. Lcc uses a newer technology called lburg. You invariably insert bugs as you do this, but the extent of the bugs is never too daunting since you know the orignal worked.
The process of debugging your own bugs makes you intimately familiar with the workings of the code. And the whole process takes much, much less time than inventing all of the code from scratch.
It has 13 operators and does better at managing the hard stuff - like semantics and code generation - than yacc and friends. As it parses, it auto-magically generates a tree. It also contains experimental functionality for changing parsers on-the-fly and producing a unity transform of the source Why?
Because a lot of things I do involve source-to-source translation.Users used an editor-based IDE (like Franz ELI with GNU Emacs, ILISP with Gnu Emacs), a special IDE usually written in Lisp (Franz, LispWorks, Macintosh Common Lisp, Golden CL on Windows, ) or even a Lisp Machine which combines the IDE with the operating system.
ABLE is an open source Common Lisp editor for Mac, Linux and Windows. ABLE's features include a listener with command history, syntax colouring, symbol completion, jump to definition, parenthesis matching, configurable indentation, Hyperspec lookup and call-tips. ABLE is .
The IDE shows this. It knows the syntax of a fixed language, invokes a compiler and uses the output from various tools, like the compiler. Common Lisp is slightly different. The IDEs are either integrated into Common Lisp (Allegro CL, LispWorks, CCL) or are in something like Emacs and connect to a running Lisp (SLIME / Emacs).
Common Lisp is a general-purpose programming language, in contrast to Lisp variants such as Emacs Lisp and AutoLISP which are extension languages embedded in particular products (GNU Emacs and AutoCAD, respectively).
