As I set up Reformat Comment commands for the languages I use most frequently (LaTeX and R), it occurred to me that maybe there's a way to make a single call to rubywrap more generic, so that we don't need a command per bundle. This is the result:

#!/usr/bin/env ruby

$LOAD_PATH << "#{ENV["TM_SUPPORT_PATH"]}/lib" require "escape"

scope = ENV["TM_SCOPE"] case scope when /comment.(block|line).number-sign./ cstring = "# " when /comment.(block|line).percentage./ cstring = "% " end

flags = "" flags += " -p "#{cstring}" " flags += " --retabify" if ENV["TM_SOFT_TABS"] == "NO"

text =`echo -n "#{e_as(STDIN.read).gsub(/[$`]/, '\\\0')}" | ruby "# {ENV["TM_SUPPORT_PATH"]}/bin/rubywrap.rb" #{flags}` print e_sn(text)

The parameters are the same as the current command, with the exception of scope, which I set to "comment.line, comment.block".

I also added a gsub to the command because it was eating latex math and R symbols ($). There's probably a better solution to that. This seems to work for me, and should be extended easily by adding lines to the case statement for other languages. One advantage is that by specifying the comment character based on the scope, it ought to work for anything; it catches comments for both bash and perl, for instance, without any extra effort. I think it's kind of cool.
