How to access environment variables inside .gdbinit and inside gdb itself?

Question

I am looking to set up the path for the source code when debugging with gdb. I chose to do that with a .gdbinit file.

Basically, it contains a command:

d

If you don't want to involve python, then this could work?

"show environment [varname] Print the value of environment variable varname to be given to your program when it starts. If you do not supply varname, print the names and values of all environment variables to be given to your program. You can abbreviate environment as env."

Maybe they could be used for conditions as well:
