Rather than having duplicate info in the symbol and the alias that has
to be resolved later on, both the symbol and the alias have a common
pointer to a separate structure containing this info.
* src/symtab.h (sym_content): New structure.
* src/symtab.c (sym_content_new, sym_content_free, symbol_free): New
* src/AnnotationList.c, src/conflicts.c, src/gram.c, src/gram.h,
* src/graphviz.c, src/ielr.c, src/output.c, src/parse-gram.y, src/print.c
* src/print-xml.c, src/print_graph.c, src/reader.c, src/reduce.c,
* src/state.h, src/symlist.c, src/symtab.c, src/symtab.h, src/tables.c:
Adjust.
* tests/input.at: Fix expectations (order changes).
Make the DOT produced by XSLT processing equivalent to the one made with the
--graph option.
* data/xslt/xml2dot.xsl: Stylistic changes, and add support for reductions.
* doc/bison.texi (Xml): Update.
* src/graphviz.c (conclude_red): Minor stylistic changes to DOT internals.
(output_red): Swap enabled and disabled reductions output, for coherence
with XSLT output.
* src/print_graph.c (print_core): Minor stylistic change to States' output.
(print_actions): Swap order of output for reductions and transitions.
* tests/local.at (AT_BISON_CHECK_XML): Ignore differences in order.
* tests/output.at: Adjust to changes in DOT internals.
* src/graphviz.c (start_graph): Use courier font.
(conclude_red): Use commas to separate attributes. Show the acceptation
as a special reduction, with a blue color and an "Acc" label. Show the
lookahead tokens between square brackets.
(output_red): No longer label default reductions.
* src/print_graph.c (print_core): Refactor spacing, and print an
additional space between a rule's rhs and its lookahead tokens. Also,
capitalize "State".
(print_actions): Style, move a declaration.

All disabled reductions should now be shown as such.
* src/graphviz.c (output_red): Here.
(conclude_red): New.
Signed-off-by: Akim Demaille <akim@lrde.epita.fr>
* src/graphviz.c (output_red): New, show reductions on the graph.
(no_reduce_bitset_init): New, initialize a bitset.
(print_token): New, print a lookahead token.
(escape): New, print "foo" as \"foo\" because Dot doesn't like quotes within
a label.
* src/graphviz.h : Adjust.
* src/print_graph.c (print_actions): Call output_red here.

The label text of nodes is centered "by default" (by the use of '\n' as
a line feed). This gives bad readability to the grammar rules shown in
state nodes, a left justification is much nicer. This is done by using '\l'
as the line feed.
In order to allow \l in the DOT file, changes to the quoting system seem
necessary.
* src/print_graph.c (print_core): Escape tokens here, instead of...
* src/graphviz.c (output_node): Here...
(escape): Using this, new.
Signed-off-by: Akim Demaille <akim@lrde.epita.fr>
* src/graphviz.c (start_graph): Use box rather than ellipsis.
* src/print_graph.c (print_core): Prefix rules with their number.
Signed-off-by: Akim Demaille <akim@lrde.epita.fr>
This handles the possibility that a "*/" might appear in
variable portions of those comments at some point in the future.
* src/graphviz.c (start_graph): Implement.
(cherry picked from commit b7666378f5)
* 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.
