Recently, I written converter program with ruby, It is enable to convert a source file of c plus plus to html format.
The converter program can change tab space to span tag of html, and color keywords.
Color of keywords is blue.
Next code is converter program.
#!/usr/bin/ruby
def convertKeyWords(arg)
if(arg =~ /(<)/ ) then
arg.gsub!($1, "<")
end
if(arg =~ /(>)/ ) then
arg.gsub!($1, ">")
end
if( arg =~ /(if)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(typedef)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(class)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(using namespace)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(while)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(for)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(void)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(int)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(double)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(char)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(#include)/ ) then
arg.gsub!($1, "<span style=\"color:blue;\"><b>" + $1 + "</b></span>")
end
if(arg =~ /(\/\/.*)/ ) then
arg.gsub!($1, "<span style=\"color:green;\"><b>" + $1 + "</b></span>")
end
arg
end
begin
if( ARGV[0] == nil ) then
puts " Usage: cpp2html.rb sourcefile"
puts " Sourcefile must be cplusplus source file."
exit(1);
end
puts "<HTML>\n<HEAD>\n<TITLE>\n" + ARGV[0]+ "\n</TITLE>\n</HEAD>\n"
unless FileTest::file?(ARGV[0]) then
puts "not file"
end
sourcefile = File.new(ARGV[0]);
comment_count = 0
indent_count = 0;
while line = sourcefile.gets()
if (/^=begin/ =~ line) then
comment_count = 1;
next
end
if (/^=end/ =~ line) then
comment_count = 0;
next
end
next if (comment_count == 1 )
line = line.chop
next if( line.empty? )
# count indent
# Following code is error! ToDo
indent_count -= 1 if ( /\}s*$/ =~ line )
# convert from tab to style
tmp = ""
for i in 0...indent_count
tmp += "<span style=\"margin-left:20px;\">"
end
# count indent
indent_count += 1 if ( /\s*\{/ =~ line )
# converting
# check key wards
line = convertKeyWords(line)
line.gsub!(/^\s+/, tmp)
line += "<br>\n"
puts line
end
puts "</HTML>"
end
