Hello all.

Does some good subj exists?  
If no, maybe it would be useful If I’ll port GeShi[1]?

Try Syntax [http://rubyforge.org/projects/syntax](http://rubyforge.org/projects/syntax) or  
CodeRay[http://rd.cycnus.de/coderay/](http://rd.cycnus.de/coderay/)  
.

require ‘tempfile’  
$VERBOSE=nil  
STDERR.reopen(Tempfile::new($$)) unless STDIN.tty?

fin, fout, \_ = ARGV  
fin = ((fin.nil? or fin == ‘-’) ? STDIN : open(fin))

ts = Tempfile::new($$), Tempfile::new($$)

command = %Q( vim -f +‘syn on’ +‘set filetype=ruby’ +‘set

- \< #{ ts[0].path } \> /dev/null 2\>&1 )  
system command  
ts.each{|t| t.open; t.rewind}  
fout.write(ts[1].read)  
ts.each{|t| t.close!}

the ‘set filetype=ruby’ functions only as a default. for instance this

ruby a.rb src.c src.html

does the right thing.

regards.

Unfortunally, they noth have very poor base of ready language files and  
rather complicated mechanism for defining new ones.

Not very universal solution. At least requires vim installed (which  
seams to  
be _very_ uncommon on non-Unix systems 😉
