Textmate is a popular code editor for Mac OS X. It supports bundles, which are customizations for particular languages (say HTML, or Ruby on Rails).
Textmate includes a default set of bundles, and you can download bundles for other languages easily.
You can also delete bundles that you do not want to use – for example, if you are a PHP programmer, you may not want bundles for other programming languages.ADVERTISEMENT
What if you deleted a bundle by accident, or learnt a new language for which you deleted the bundles in Textmate earlier? A simple Terminal command can bring them back.
Ensure that TextMate is not running, then enter the command below to reset deleted bundles (ie. recover deleted bundles):
