As an Eclipse IDE plug-in NCL Eclipse can be easily integrated with others plug-ins---for instance, those supporting other ISDB-Tb and ITU-T standard languages (such as Lua and Java).
NCL Eclipse 1.0
The first stable version of NCL Eclipse was named "NCL Eclipse 1.0". This version has included support to syntax highlighting, folding (which allows the author to hide parts of source code according with his needs), wizards to create simple documents, auto-formatting, document, marking error validation, contextual content suggestion and an outline view (which shows the document content as a tree). To provide the marking error validation, all NCL Eclipse versions uses the NCL Validator (validation framework of NCL documents). This first version was very well accepted by the community of NCL developers, which gave several feedbacks. The NCL Eclipse evolution is strongly based on these feedbacks.
NCL Eclipse 1.4
The NCL Eclipse 1.1, 1.2, and 1.3 have focused mainly on fixing bugs from the previous version. The next big changes came with 1.4 version of NCL Eclipse. That version brings program visualization, media previews and hypertext navigation. Additionally, a new plug-in aimed to integrate NCL Eclipse with NCL Club was included in the same package. As pointed out before, the integration with NCL Club allows for beginners to start learning NCL based on real-world examples. The internationalization support for English, Spanish and Portuguese was also included in this version.
NCL Eclipse 1.5
The latest stable, and current version, is "NCL Eclipse 1.5". This version contains some improvements in source code. As new feature, this version came with support to semi-automatic error correction and option to run the NCL document, provided by a virtual machine running the Ginga-NCL emulator.
