Entries are terminated # at the next @def* (which begins a new entry) or, for C files, a line # that begins with '*/' without leading spaces (this assumes that the # texinfo snippet is within a C-style /* */ comment). # if ($ARGV[0] eq "-v") { $verbose = 1; shift; } $srcdir = shift; $outfile = shift; if ($outfile !~ /\S/ || ! -f "$srcdir/Makefile.in" ) { print STDERR "Usage: gather-docs [-v] srcdir outfile.txi [files with snippets in them ...]\n"; exit 1; } $errors = 0; for $in (@ARGV) { if (!open(IN, "$srcdir/$in")) { print STDERR "Cannot open $srcdir/$in for reading: $!\n"; $errors ++; } else { $first = 1; $pertinent = 0; $man_mode = 0; $line = 0; while (<IN>) { $line ++; $pertinent = 1 if /^\@def[a-z]*[a-wyz] /; $pertinent = 0 if /^\*\//; next unless $pertinent; if (/^\@def[a-z]*[a-wyz] /) { ($name) = m/[^\(]* ([^\( \t\r\n\@]+) *(\(|\@?$)/; $name =~ s/[ ]*\@?$//; $key = $name; $key =~ tr/A-Z/a-z/; $key =~ s/[^a-z0-9]+/ /g; $name{$key} = $node; $lines{$key} = ''; $src_file{$key} = $in; $src_line{$key} = $line; print "\nReading $in :" if $verbose && $first; $first = 0; print " $name" if $verbose; $node_lines{$key} .= $_; } else { $node_lines{$key} .= $_; } $pertinent = 0 if /^\@end def/; } close (IN); } } print "\n" if $verbose; exit $errors if $errors; if (!open (OUT, "> $outfile")) { print STDERR "Cannot open $outfile for writing: $!\n"; $errors ++; next; } print "Writing $outfile\n" if $verbose; print OUT "\@c Automatically generated from *.c and others (the comments before\n"; print OUT "\@c each entry tell you which file and where in that file).
