(safegetc): New function to deal with EOF gracefully. (literalchar); new function to deal with reading \ escapes. (lex): Use literalchar. (lex): Implemented "..." tokens. (literalchar, lex, parse_percent_token): Made tokenbuffer always contain the token. This includes growing the token buffer while reading an integer. (parse_percent_token): Replaced if-else statement with percent_table. (parse_percent_token): Added % declarations as another way to specify the flags -n, -l, and -r. Also added hooks for -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires major changes to files.c. (lex) Retain in the incoming stream a character following an incorrect '/'. (skip_white_space, lex): Revised most error messages and changed fatal to warn to avoid aborting. (percent_table): Added %thong declarations.
This directory contains the Bison parser generator. See the file INSTALL for compilation and installation instructions. It was once true that, when installing Bison on Sequent (or Pyramid?) systems, you had to be in the Berkeley universe. This may no longer be true; we have no way to tell. On VMS, you will probably have to create Makefile from Makefile.in by hand. Remember to do `SET COMMAND BISON' to install the data in `BISON.CLD'. Send bug reports to bug-gnu-utils@prep.ai.mit.edu. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report.
