This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
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.
* 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.
