(Option Cross Key): Likewise.
* src/print-xml.c (print_core): Don't print a reduction's lookahead set
next to an item whose dot is not at the end of the RHS even if it
happens to be associated with the same rule.
* src/print.c (print_core): Likewise.
* tests/conflicts.at (Unresolved SR Conflicts): Update output.
(Resolved SR Conflicts): Update output.
* tests/regression.at (Extra lookahead sets in report): New test case.
* 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.
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.
elsewhere.
* src/print-xml.c: Prefer "const" after types; that's more consistent.
(xml_printf): Indent just 1 space for level.
(e_char, xlate_char): Remove.
(xml_escape_string): Rewrite to avoid undefined behavior (used
storage that was freed from the stack).
(xml_escape_n): Don't bother checking for subscript error.
