FileTrunc
ARCHIVED! See: https://github.com/melsbacksfriend/Melsbackslib
The first header in an awesome library called Melsbackslib
This will be archived when the second header is made. Updates will continue in that repo.
This header takes a C string containing a file and path and returns a C++ string with just the folder name.
This can be used with argv[0] to set the current working dir to the location of the file like in the example.
Building the example
git clone --recursive https://github.com/melsbacksfriend/FileTrunc.git
cd FileTrunc/FileTrunc-Example
g++ FileTrunc.cpp -std=c++17 -o FileTrunc
Limitations
Doesn't work on Windows due to using backslashes.
