This release has the following enhancements AFLEX ----- The Input/Output structure of generated scanners has been changed to make things work as users expect. Standard_Input and Standard_Output should now end up where they were before the call to YYLex. AYACC ----- AYACC would generate illegal package names given certain input file names. This was previously corrected in the VADS6 version, but the change wasn't propogated to the main sources due to an error in configuration management. Thank you to Michael Schwartz for pointing this out. AYACC wouldn't work under some versions of the ALSYS compiler due to an erroneous construct involving order of parameter evaluation in the file lalr_symbol_info_body.a. Thank you to delaunay@ensisun.imag.fr for this fix. Added checks and error messages for parse stack overflow in generated parsers. Thank you to Susan Eilers for these patches. AYACC would fail silently if it couldn't open it's output files. The ada_parser example (which is very frequently used as a basis for tools) had some errors which caused it to reject legal code. S A McConnell contributed a set of revisions which allow the ada_parser to parse the entire ACVC 1.11 collection. If you received this announcement via e-mail and you don't wish to be notified of further Aflex and Ayacc developments, or if you received multiple copies of this message, please send mail to irus-software-request@ics.uci.edu and request to be deleted from the mailing list.

Aflex and ayacc are similar to the Unix tools lex and yacc, but they are written in Ada and generate Ada output. They were developed by the Arcadia Project at the University of California, Irvine. Aflex is based on the tool 'flex' written by Vern Paxson. These tools are copyrighted, but are freely redistributable. There is no warranty of any kind (see the copyright notice above.) However we do ask that you report any problems you encounter as we use these tools ourselves and we want to fix any bugs that are found. You may give this software to others, but we prefer that those who can get it directly from us to insure that all users are running the latest version. We also ask that you send electronic mail to the address irus-software-request@ics.uci.edu giving your name, your organization, a paper mail address, and your e-mail address (either an Internet address or a UUCP path relative to a well-known site such as uunet.) A form is provided below for your convenience. We will use this information to set up a mailing list to announce new versions of aflex and ayacc, as well as new software that is expected to be made available. The distribution is currently available on the machine liege.ics.uci.edu in ~ftp/pub/irus/aflex-ayacc_1.3a.tar.Z. Full instructions for retrieving and unpacking are enclosed below. If you have trouble retrieving or unpacking the distribution send mail to irus-software-request@ics.uci.edu (or via UUCP to uunet!sdcsvax!ucivax!irus-software-request) If you have trouble with the tools information on how to report bugs is present within their directories. ------------------------------- cut here ------------------------------- IRUS software user registration form 1.

E-mail address for contact person: ------------------------------- cut here ------------------------------- How to obtain aflex and ayacc via anonymous FTP 1. FTP to the machine liege.ics.uci.edu (internet address 128.195.1.5) 2. When asked for a username use 'anonymous' 3. When asked for a password use your username on your local machine. 4. Change directory (cd) into the pub/irus directory. 5. Set a file transfer mode that will allow you to transfer binary files. One way to do this that usually works is to issue the command 'type tenex' 6. Type the command 'get aflex-ayacc_1.3a.tar.Z' 7. Quit FTP. 8. You now have a compressed tar file containing the source for aflex. 9. You need to uncompress the file by typing 'uncompress aflex-ayacc_1.3a.tar.Z' 10. Now untar the file to create the source and documentation tree by typing 'tar xvf aflex-ayacc_1.3a.tar' at the Unix prompt. 11. Read the README files in the aflex/README and ayacc/src/READ_ME to find out how to compile the tools. If you are using the Verdix Ada Developemnt System Version 6 be sure to read the VADS6.README files in the aflex and ayacc directories before building them.
