I have a textmate color theme I really like this, But I am a hardcore vim user. Is there an easy (painless) way for me to use this color scheme with vim?
There are a lot of textmate color schemes for textmate in vim. Maybe you can find someone who already implemented it.
Searching in google for textmate theme vim, the first result is:
A GUI only color scheme based on the Railscasts TextMate theme.
Is this theme (Railcasts theme) what you're looking for?
You can convert any Textmate color scheme to vim by using coloration.
The default syntax highlighting in the Janus distro of VIM is what you are looking for. I explain how to download it in my Textmate to VIM guide
