While working with SDL, I found that I kept using the same
pattern over and over:
- Get the current clip rectangle.
- Set a new clip rectangle.
- restore the old clip rectangle on scope (exit).
Instead of writing that code again and again, I wrote a simple
function that returns a struct which restores the old clip
rectangle in it's destructor. This works great but now dscanner
complains about the variable being unused.
Is there a way tell dscanner that a variable is intentionally
unused?
You can disable the "unused variable check" for the module in the
dscanner.ini file located in the project directory see
https://github.com/dlang-community/D-Scanner#selecting-modules-for-a-specific-check.
More simple is to understand D-Scanner limitations and accept
that warnings are only warnings and that a message doesn't
necessarily mean that there's something to do.
