Is anyone out there aware of yacc and lex clones that produce MS Windows compatible code. In other words I am looking for yacc and lex that produce code that can be linked to Windows applications. I would be happy to hear about any other parser generators that produce Windows compatible code. Thanks Jerry Sullivan

Lex and Yacc have really nothing to do with Windows, so your question should be something like "is there a lex/yacc package that works with compilers that can be used to build Windows applications?". The answer is yes. I'm building such an application. I'm using MKS Lex/Yacc. You can get a good deal on the package from either Programmer's Paradise of Programmer's Shop. Discounted price is around $200. I'm fully satisfied with this product. -- Marco -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "Xerox sues somebody for copying?" -- David Letterman -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Discounted price >is around $200. I'm fully satisfied with this product. On simtel20 and other sites there are copies of flex and bison for the PC. Flex is a replacement for lex and bison is a replacement for yacc. There is a restriction on the use of bison-generated scanners, though. Otherwise they are free. I understand that there is a public domain and unrestricted yacc on a Berkeley distribution, but I don't know of a port to the PC. Eric Hughes hughes@ocf.berkeley.edu

Are you linking the parser to your Windows application or just executing the parser from a Windows application as a DOS "process"? I need to do the former. It is my understanding that just because somthing compiles with MS C does not imply that it will work run under Windows as part of a Windows application. In other words, y.tab.c (the parser source code generated by yacc) produced by MKS yacc may do things acceptable under DOS but not Windows (ie segment arithmatic, requiring incompatible libraries, etc). I may be mistaken, I am new to Windows and DOS but have used yacc and lex extensively. I want to call yyparse() from a Windows application. Note that it is not enough to be able to run the parser as a DOS "process" because I need access to data structures built as a side effect of the parsing process. I don't think it is possible to pass data structures to a Windows application from a DOS "process" spawned by the application. I may be wrong. I am aware of MKS yacc and lex. According to MKS, the output of MKS yacc is indeed incompatible with Windows. They did not say why. They said that the parser produced by MKS yacc cannot be linked to a Windows application. They said it will run as a DOS application under Windows. Unfortunately, that is not what I need. The MKS person suggested I chek back in 6 months. Thanks, Jerry Sullivan

(or is it lex output? I'm sorry I don't know better). Whatever, the routine you run to generate the tables still has to run under DOS, and then you take the generated C code and edit it (with a provided macro) to make it Actor source. Actor has a built in something that will take these tables, along with your input from a command line, and convert it all into actor code which it then executes. I think they called it the "data driven lexical analyzer." Anyway, I used it to make a small command language for a wargame I'm writing, which says something about putting powerful tools in the hands of incompent people :). -- Paul Gyugyi gyugyi@earthsea.stanford.edu
