Denny + + * src/getargs.c (version): Update copyright year. + +2007-10-09 Joel E. Denny + + Make xml2dot.xsl and --graph produce the same output. + * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a ` ' + instead of a `\n'. That is, don't add escapes yet or they'll be doubly + escaped later. + (xsl:template name="output-node"): Use the new escape template instead + of the string-replace template directly. + (xsl:template name="output-edge"): Likewise. + (xsl:template name="escape"): New, escapes backslashes and newlines in + addition to quotation marks. + * src/graphviz.c (start_graph, output_node, output_edge): Add + whitespace to output for legibility. + + Make xml2text.xsl and --report produce the same output, and remove the + XML "conflicts" element since a conflict summary is easily extracted + from the automaton. + * data/xslt/bison.xsl: New. + (xsl:template match="state" mode="bison:count-conflicts): New. + * data/xslt/xml2text.xsl: Import bison.xsl. + (xsl:template match="bison-xml-report"): Instead of styling the + "conflicts" element, style the "automaton" element with mode + "conflicts". Unlike the former, the latter lists S/R and R/R + conflicts for a state on the same line. + (xsl:template match="conflicts"): Remove. + (xsl:template match="conflict"): Remove. + (xsl:template match="terminal"): Line-wrap the list of rules in which + the terminal is used. + (xsl:template match="nonterminal"): Likewise for nonterminals. + (xsl:template match="automaton" mode="conflicts"): New. + (xsl:template match="state" mode="conflicts"): New. + (xsl:template name="line-wrap"): New. + (xsl:template name="ws-search"): New. + * data/xslt/xml2xhtml.xsl: Import bison.xsl. + (xsl:template match="bison-xml-report"): Instead of styling the + "conflicts" element, style the "automaton" element with mode + "conflicts." + (xsl:template match="conflicts"): Remove. + (xsl:template match="conflict"): Remove. + (xsl:template match="automaton" mode="conflicts"): New. + (xsl:template match="state" mode="conflicts): New. + * src/conflicts.c (conflicts_output_xml): Remove. + * src/conflicts.h (conflicts_output_xml): Remove prototype. + * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml. + * src/print.c (print_grammar): Consistently wrap at the 66th column so + the corresponding XSLT is easier. Also, never wrap between a word and + the comma that follows it. + +2007-10-08 Joel E. Denny + + Improve C++ namespace support. Discussed starting at + . + * data/c++.m4: (b4_namespace_ref, b4_namespace_open, + b4_namespace_close): New macros that interpret the %define variable + "namespace" so its value can contain "::" to indicate nested + namespaces. + * data/glr.cc (b4_namespace): Don't define, and replace all uses with + the above macros. + * data/lalr1.cc (b4_namespace): Likewise. + * data/location.cc (b4_namespace): Likewise. + * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry + inside a new table in the general %define entry. Document `%define + namespace' there as well. Point the %name-prefix entry to it since it + explains it more completely in the case of C++. + (C++ Bison Interface): Mention `%define namespace' instead of + %name-prefix. + (Table of Symbols): Remove the `%define push_pull' entry. The %define + entry suffices. + * tests/c++.at (Relative namespace references): New test case. + (Absolute namespace references): New test case. + (Syntactically invalid namespace references): New test case. + * tests/input.at (C++ namespace reference errors): New test case. + +2007-10-08 Joel E.

Denny + + Fix some error-reporting macro bugs. + * data/bison.m4 (b4_cat): New. + (b4_error, b4_error_at): Use b4_cat to send error directives directly + to stdout so they don't become arguments to other macros. Update + comments and add examples. + (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and + add examples. + (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately + after printing the error directive so that M4 doesn't report subsequent + problems that are induced by this problem. + * src/scan-skel.l: Recognize @` digraph outside of directive arguments + instead of just in them. Recognize @\n in both places. Both expand to + the empty string. Needed by b4_cat. + * tests/skeletons.at (Complaining during macro argument expansion): + New test case. + (Fatal errors make M4 exit immediately): New test case. + +2007-10-04 Joel E.

This + will go away when we mv push.c yacc.c. + * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that + push parsing is not supported since unused %define variables are + reported anyway. + * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove. + * src/muscle_tab.h (muscle_percent_define_check_values): Update + comments for consistency with b4_percent_define_check_values. + * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag + muscles. + * src/parse-gram.y (PERCENT_PUSH_PARSER, PERCENT_PUSH_PULL_PARSER): + Remove. + (prologue_declaration): Remove %push-parser and %push-pull-parser + rules. + * src/scan-gram.l (%push-parser, %push-pull-parser): Remove rules. + * tests/calc.at: Update declarations. + * tests/input.at (%define enum variables): New test case. + * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Update + declaration. + (Push Parsing: Multiple impure instances): Update declaration. + (Push Parsing: Unsupported Skeletons): New test case. + * tests/torture.at (Exploding the Stack Size with Alloca): Update + declaration. + (Exploding the Stack Size with Malloc): Update declaration. + +2007-09-24 Wojciech Polak + + Add XSLT transformations. + + * data/xslt/xml2dot.xsl: Transform XML into DOT. + * data/xslt/xml2text.xsl: Transform XML into plain text. + * data/xslt/xml2xhtml.xsl: Transform XML into XHTML. + * data/Makefile.am (xsltdir): New variable. + (dist_xslt_DATA): Add xslt/*.xsl files. + +2007-09-23 Paul Eggert + + * src/conflicts.c (log_resolution): Fix indenting bugs I introduced. + Problem reported by Wojciech Polak. + * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2. + (xml_printf): Undo change I made on 21 September; that is, + indent 2 spaces, not 1. + +2007-09-23 Joel E.
