* 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.
