Recently my Lua scripts started to get out of hand because I'm adding more and more common utility functions and custom Lua classes. Remembering function signatures became more difficult and using classes without auto-complete is pure pain. I decided to improve my original Lua editor (was designed originally only to auto-complete APIs exposed from my game), and I think more people could benefit from it. I present Intellua:

Intellua is a open source (although the code is still messy and undocumented now so it is not recommended to look at it now.) C# project base on scintilla and scintillaNET that provides auto-complete via static code analysis.

Features are:

• Auto-completion and brief document for functions, variables, class and class members.
• Game APIs and classes can be documented with Doxygen and import into Intellua (specifically designed for those binded by luabind, but others might also apply)
• Lua functions and classes can be declared and documented with special lua comments.
• Object type deduction through assignments and function return type.
• Manually assigning type for objects.
• Independent from execution environment.

Most other Lua editors seems to support auto-complete via dynamically inspecting tables. From my past experience (might be wrong since years has past and it could improve.) the result might be messy(unneeded private stuff appears) or inacurrate(inherited members through meta-table missing). By using static analysis Intellua believe a object is what you told Intellua it is, this gives more control over the result.

Here's a demo of writing and using a simple class in Intellua
