`bison ', use m4_index instead of m4_substr since chopping up a string containing M4-special characters causes problems here. Fix a couple of bugs related to special characters in user-specified file names, and make it easier for skeletons to compute output file names with the same file name prefix as Bison-computed output file names. * data/glr.cc, data/push.c, data/yacc.c: In @output, use b4_parser_file_name and b4_spec_defines_file instead of @output_parser_name@ and @output_header_name@, which are now redundant. * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use b4_parser_file_name, b4_spec_defines_file, and the new @basename(FILENAME@) instead of @output_parser_name@ and @output_header_name@, which inappropriately escaped the file names as C string literals. * src/files.c (all_but_ext): Remove static qualifier. (compute_output_file_names): Move `free (all_but_ext)' to... (output_file_names_free): ... here since all_but_ext is needed later. * src/files.h (all_but_ext): Extern. * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does exactly what MUSCLE_INSERT_STRING used to do. (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special characters are escaped properly. * src/output.c (prepare): Define muscle file_name_all_but_ext as all_but_ext. For pkgdatadir muscle, maintain previous functionality by using MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem is that b4_pkgdatadir is used inside m4_include in the skeletons, so digraphs would never be expanded. Hopefully no one has M4-special characters in his Bison installation path. * src/scan-skel.l: Don't parse @output_header_name@ and @output_parser_name@ anymore since they're now redundant. In @output, use decode_at_digraphs. Parse a new @basename command that invokes last_component. (decode_at_digraphs): New. (BASE_QPUTS): Remove unused. * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro. (Output file name): New tests.
This directory contains the Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the file doc/FAQ for frequently asked questions. Bison requires GNU m4 1.4.3 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz Bison can work with pre-1.4.3 distributions of GNU m4 if they are sufficiently patched, but if you encounter a bug with an older distribution and report a bug we will probably suggest that you upgrade to 1.4.3 as the first step in trying to fix it. Please send bug reports to <bug-bison@gnu.org>. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005 Free Software Foundation, Inc.
