[TxMt] Problem with tm_dialog

[Leonardo Querzoni]

Hi,

Some weeks ago I wrote this ruby script that works inside a TextMate  
command to build a list of references declared in Latex files and let  
the user select the reference he wants to insert in the text:

-----------------------
#!/usr/bin/env ruby -wKU

SUPPORT = ENV['TM_SUPPORT_PATH']
DIALOG = SUPPORT + '/bin/tm_dialog'

require SUPPORT + '/lib/escape'
require SUPPORT + '/lib/plist'
require 'pathname'
require 'find'

refs = []

Find.find(ENV['TM_PROJECT_DIRECTORY']) do |f|
   file_name = File.basename(f)
   if  /\.(tex)$/ =~ file_name
	File.open(file_name,"r") do |infile|
		infile.each_line do |line|
			if line =~ /.*\label\{.*/
				line = line.gsub(/.*\label\{(.*)\}.*/, '\1').chomp
				refs << {
					'title' => line,
					'code'  => "\\ref{#{line}}"
				}
			end
		end
	end
   end
end
abort if refs.empty?

plist = { "menuItems" => refs }.to_plist
res = PropertyList::load(`#{e_sh DIALOG} -up #{e_sh plist}`)
abort unless res.has_key? "selectedMenuItem"

print %(#{res["selectedMenuItem"]['code']})
-----------------------

Since the last updates (both of TextMate and its bundles), the script  
does not work anymore.

When I invoke it, it gives me back the following error.

-----------------------
tm_dialog: you have updated the tm_dialog tool to v7 but the Dialog  
plug-in running is still at v4.
tm_dialog: either checkout the PlugIns folder from the repository or  
remove your checkout of the Support folder.
tm_dialog: if you did checkout the PlugIns folder, you need to  
relaunch TextMate to load the new plug-in.
/tmp/temp_textmate.ZcyesN:32:in `load': Cannot parse a NULL or zero- 
length data (PropertyListError)
	from /tmp/temp_textmate.ZcyesN:32
-----------------------

I'm a TextMate newbe, thus I'm not sure, but from the error message  
it seems like I need to update the Dialog.tmplugin file. How can I  
fix this ?

Cheers,
Leonardo
