>I made a Tumblr sugar for Espresso. It comes with all the goodies - snippets, code complete and it works properly with the itemizer.
I’ve missed a few snippets so far, but I’ll get around to adding them. However, every tag is in the code-sense, and the syntax highlighting works a treat.
There’s still a few things I need to add:
* Finish adding all the snippets
* Fix some code-sense bugs (The codesense doesn’t work within HTML tags, but it works outside them)
* Creating and uploading of posts to Tumblr, like the Textmate bundle.
* View tag documentation
* Wrap content in {block} tags
But other than that, it’s working smoothly. You can download it via Github. Just download the source, and rename the folder to tumblr.sugar, double-click and enjoy.
