RVS supports common C and C++ compilers and language standards by default (see the RVS support specification for a non-exhastive list).
If you use a modified compiler or language standard, the Cext Editor makes it easy to manage compiler extensions. It has many useful features including syntax highlighting, auto-completion, diff highlighting, and error messages for syntax errors. You can also enter sample code, and test your Cext file against it.
The Cext Editor includes built-in Cext reference information and guidance.
