Nimgen supports compiling in C/C++ sources as well as loading in dynamic libraries at this time. Support for static libraries (.a, .lib) are still to come.
Environment variables are supported via Nim's string interpolation `%` symbol imported from the `strutils` module. Simply use double quotes to enclose any value and put `${}` around the environment variable name. In addition, the `output` var from the n.global section is available as ${output}. For example:
[n.global]
output="src/path"
[n.include]
"${output}/library/include"
To see examples of nimgen in action check out the following wrappers:-
