color editor is…
A syntax color highlighting editor for Eclipse.
ColorEditor uses JEdit’s syntax highlighting mode files.
This is a beta release since a few things don’t work. The biggest issue that doesn’t currently work is supporting a partition that contains another partition(s). JEdit uses this "span within a span” idea in a lot of places but as far as I can tell it will take a good bit of work to support overlapping partitions in Eclipse.
The plugin currently supports highlighting for around 74 different file types.
