LaTeX and require_cmd.rb - TextMate

1 Dec 2008


      Hi
Misadventures of a Wizard's Apprentice :
I found in this message : http://lists.macromates.com/textmate/2007-February/017504.html
this idea
ENV['PATH'] = %x{sh -c '. "$BASH_ENV"; echo $PATH'}
I put this line in the file require_cmd.rb and with this line, I can  
compile
  without setting the PATH in the Shell Variables.
I would like to know if this idea is fine or if it' dangerous ...

the code :
ENV['PATH'] = %x{sh -c '. "$BASH_ENV"; echo $PATH'}
require ENV["TM_SUPPORT_PATH"] + "/lib/escape"
require ENV["TM_SUPPORT_PATH"] + "/lib/exit_codes"
module TextMate
  class << self
   def require_cmd(cmd)
       unless File.executable?(cmd) or ENV['PATH'].split(':').any? { | 
dir| File.executable? File.join(dir, cmd) }
         TextMate::HTMLOutput.show(:title => "Can't find “#{cmd}” on  
PATH.", :sub_title => "") do |io|
           io << "<p>The current PATH is:</p>"
           io << "<blockquote>"
           ENV["PATH"].split(":").each do |p|
             io << htmlize(p + "\n")
           end
           io << "</blockquote>"
           io << "<p>Please add the directory containing  
“<code>#{cmd}</code>” to <code>PATH</code> in TextMate's Shell  
Variables preferences.</p>"
           io << "<p>Alternatively, the PATH can be retrieved from  
Terminal but this requires a relaunch: "
           io << "<button onclick= 
"TextMate.system('#{(ENV["TM_SUPPORT_PATH"]+"/bin/ 
set_tm_path.sh").gsub(" ", "\\\\ ")}', null)">Set PATH and  
Relaunch.</button></p>"
         end
         TextMate.exit_show_html
       end
     end
   end
end
