Topic: Write Your Forum Posts in TextMate
Okay, not exactly Rails related, but I think everyone here who has TextMate will be interested in this.
Tired of typing Ruby code in the browser? Did you know you can install an "Edit in TextMate" command in Safari and many other applications (including Mail)? Just install the TextMate Input manager by going to the following menu in TextMate: Bundles > TextMate > Install "Edit in TextMate". After doing this you can use the command-control-E key command while in a text field to start editing away in TextMate. After you're done, save the document and close the window. This takes you straight back to the other application with the updated text field.
Combine this with the BBCode TextMate Bundle I just finished creating to make this perfect for editing forum postings. This even handles proper syntax highlighting and snippets for the specified language while in the code tag! It's still under early development, so please give it a try and let me know how it goes.
