I have a function which takes a filepath as an argument. How can I extract the basename (file.c in the example below) from the argument?




LaTeX includes a filepath parser (the exact syntax it parses depends on the system)



\typeout{area: \filename@area}

\typeout{name: \filename@base}

\typeout{ext: \filename@ext}


Produces this on the terminal:

area: path/to/
name: file
ext: c
