Turbo Pascal Lex and Yacc Version 4.1 Compiler generator toolset for Turbo/Borland/Free Pascal and Delphi Copyright (c) 1990-2000 by Albert Graef Copyright (c) 1996 by Berend de Boer Copyright (c) 19*** by Michael Van Canneyt This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

About this Package ===== ==== ======= This is Version 4.1 of TPLY (Turbo Pascal Lex and Yacc), a compiler generator for Turbo Pascal and compatibles. The package contains two programs, TP Lex and Yacc, which are approximately compatible with the UNIX utilities Lex and Yacc, but are written in, and produce code for the Turbo Pascal programming language. The present version works with all recent flavours of Turbo/Borland Pascal, including Delphi, and with the Free Pascal Compiler, a GPL'ed Turbo Pascal-compatible compiler for a variety of different systems including DOS, Win32, OS/2 and Linux. Recent information about TPLY and the sources are available from the TPLY homepage: http://www.musikwissenschaft.uni-mainz.de/~ag/tply This site also contains links to various contributions of TPLY users that are not included in this package, so make sure you take a look at it. For information about the Free Pascal Compiler, please refer to: http://www.freepascal.org The manual can be found in the files tply.tex (TeX version) and tply.doc (ASCII version) contained in the package. An extended version of the manual has also been published in the CCAI journal (A. Graef, TP Lex and Yacc: A compiler generator toolset for Turbo Pascal, Journal of Communication and Cognition - Artificial Intelligence (CCAI), 12(4), 1995, pp. 383-424). Furthermore, there is one book I know of which devotes three chapters to TP Lex/Yacc; unfortunately, it is written in French ;-) (Nino Silverio, Realiser un compilateur: Les outil Lex et Yacc, Editions Eyrolles, France, 1994, ISBN 2-212-08834-5). License ======= Since version 4.0, TPLY and its derivatives are distributed under the GNU General Public License (Version 2 or later); see the file COPYING for details. Authors ======= The original version of this package is Albert Graef . He still maintains the package (as time permits ;-). Berend de Boer adapted TPLY to take advantage of the large memory models in Borland Pascal 7.0 and Delphi. Michael Van Canneyt , who maintains the Linux version of the Free Pascal compiler, ported TPLY to Free Pascal. History ======= *** Version 2.0 Albert Graef Around 1990 (or even 1***9?). First public release. I advertised this one to Borland, but they wouldn't take notice. ;-) *** Version 3.0 Albert Graef 1991. Lots of changes to make TPLY more compatible to UNIX Lex/Yacc. Moreover, all DFA and LALR parser construction algorithms were reimplemented from scratch in order to improve efficiency. *** Version 3.0a Albert Graef May 1992. Bug fix release. *** Version 4.0 Berend de Boer Oct 1996. This version differs with the previous release, 3.0a, that it compiles under Dos, DPMI, Windows, Delphi 16 and Delphi 32. This version is/was maintained by Berend de Boer . For the protected mode or win32 platforms Lex and Yacc also have significantly larger tables. The win32 version in fact can have unlimited tables because you have 2GB to store things :-) The 16-bit DPMI platforms have tables extended as large as possible without changing basic Lex or Yacc sources. This version was ported to Free Pascal by Michael Van Canneyt (April 19***). *** Version 4.1 Michael Van Canneyt Albert Graef May 19***. Merges the Turbo and Free Pascal versions into a single package. *** Version 4.1a Albert Graef Apr 2000. Again a bug fix release ("memory overflow" messages at startup, Lex producing weird output when regular definitions have trailing blanks, fpc compilation problems). Also removes (in the fpc version) the memory usage statistics which are rather misleading when the heap is resized dynamically. Tested with fpc 0.99.14. Contents of the Package ======== == === ======= The TP Lex and Yacc programs consist of 23 modules with about 11000 lines of code. A short description of each of the source modules is given below. LEX PAS TP Lex main program LEXBASE PAS base module (global declarations) LEXDFA PAS DFA construction algorithm LEXLIB PAS TP Lex library unit LEXLIST PAS listing operations LEXMSGS PAS messages and error handling LEXOPT PAS DFA optimization algorithm LEXPOS PAS operations to construct the position table LEXRULES PAS parser for TP Lex grammar rules LEXTABLE PAS internal tables used by the TP Lex program YACC PAS TP Yacc parser and main program YACC Y TP Yacc source for YACC.PAS YACCBASE PAS base module (global declarations) YACCCLOS PAS closure and first set construction algorithms YACCLIB PAS TP Yacc library unit YACCLOOK PAS LALR lookahead computation algorithm YACCLR0 PAS LR(0) set construction algorithm YACCMSGS PAS messages and error handling YACCPARS PAS parse table construction YACCSEM PAS semantic routines of the TP Yacc parser YACCTABL PAS internal tables used by the TP Yacc program YYLEX COD code template for the lexical analyzer routine YYPARSE COD code template for the LALR parser routine Besides this, the package also contains the following docs: COPYING GNU General Public License README this file TPLY DOC ASCII version of the manual TPLY TEX TeX version of the manual Furthermore, the EXAMPLE subdir contains various sample TP Lex and Yacc programs, such as a (Standard) Pascal parser and a complete TPLY cross referencing utility named `yref'. Installation ============ The items to be installed are the executables of TP Lex and Yacc (compiled from the lex.pas and yacc.pas programs), the Lex and Yacc code templates (*.cod files), and the LexLib and YaccLib library units (compiled from lexlib.pas and yacclib.pas). For the Free Pascal/Linux version, a Makefile is provided. To install, issue the command `make' (maybe you have to edit the Makefile before this to reflect your setup) and then `make install'. Note that in the Linux version the executables will be named `plex' and `pyacc' to avoid name clashes with the corresponding UNIX utilities. For the Turbo/Borland/Free Pascal versions under DOS and Windows, several DOS batch files are provided: MAKEDOS.BAT - makes a real mode executable. Compiles with Turbo Pascal 6.0 to Borland Pascal 7.0. MAKEDPMI.BAT - makes a dos protected mode executable. Needs Borland Pascal 7.0. MAKEBPW.BAT - makes a 16-bit Windows executable. Needs Borland Pascal 7.0 or Borland Pascal for Windows. MAKED16.BAT - makes a 16-bit Windows executable. Needs Delphi 1.X. MAKED32.BAT - makes a 32-bit Windows NT or Windows 95 console application. Needs Delphi 2.X. MAKEFPC.BAT - makes a 32 bit executable. Needs the Free Pascal compiler. These will compile the programs lex.pas and yacc.pas, as well as the units lexlib.pas and yacclib.pas. To install, copy the executables lex.exe and yacc.exe along with the code templates yylex.cod and yyparse.cod to a place somewhere on your DOS path. Furthermore, copy the compiled lexlib and yacclib units to a directory which is searched for unit files by your compiler. (NB1: I currently have no means to check whether these batch files work except for the makedos and makefpc files. If you have problems with any of the other files, please let me know.) (NB2: The type of compiler used to compile TP Lex and Yacc affects the sizes of internal tables of these programs. If you want to be able to compile large grammars, you should therefore compile TP Lex/Yacc using one of the 32 bit compilers like BP 7.0 or Free Pascal. Note that the Pascal output generated by TP Lex and Yacc is independent of the type of compiler with which the programs were compiled. Thus the generated code can be used with any of the supported compilers, regardless of the type of compiler used to compile the TP Lex and Yacc programs themselves. You only have to compile the LexLib and YaccLib units separately for each type of compiler which will be used to compile TP Lex/Yacc generated programs.) To complete the installation, you might also wish to install the contents of the example subdir in a directory of your choice. As soon as the installation is finished, you can perform a quick bootstrap test (under DOS/Windows) with the command `yacc yacc.y test.pas'. You can then compare the distributed `yacc.pas' against the generated `test.pas' with the DOS `fc' command. The two files should not differ. An analogous test can be run under fpc/Linux using `make test'. That's it! Hope you enjoy using this package.
