Camembert is a Free, Open source, lightweight IDE, written in Fantom. It's multi-platform and can run on many platforms (Linux, Max, Windows...)
It supports Many languages such as Fantom, Go, Node.js ,Maven, Python, Ruby etc...
The focus is on being a fairly "simple" editor yet provide built-in access to each language documentation as well as running commands.
Over time I have found out the most advanced IDE's, while very effective, tend to make me a bit lazy and often I will learn a lot more by looking at the proper API documentation than just using completion "blindly".
On the other hand lightweight editor often do not give any built-in access to the documentation at all so if you are somewhat new to a language it will be difficult.
