Transform TextMate Snippets into NetBeans Code Templates

README.md

!!! Obselete Gist !!! Go to http://github.com/nowhereman/snippets-converter

Convert TextMate Snippets into NetBeans Code Templates.

How to use (for Ubuntu):

Copy your TextMate Snippets directory into the tmsnippets2netbeans folder, run ruby tmsnippets2netbeans.rb This will convert all you need and create a XML file.

Put the org-netbeans-modules-editor-settings-CustomCodeTemplates.xml file into

/home/username/.netbeans/6.8/config/Editors/text/x-ruby/CodeTemplates folder

Requirement:

you'll need Nokogiri gem in order to use this script, so : sudo gem install nokogiri
