Accessing Command Line Arguments

Problem

You want to access the command line arguments passed to your MzScheme program was called with.

Solution

The command line arguments are stored as a vector of string in the parameter named current-command-line-arguments. To access them, apply the parameter:

> (current-command-line-arguments)
#("these" "are" "the" "arguments")

Discussion

To pass command line arguments to your script, MzScheme must be called with the -r flag (for scripts that aren't in a module), or the -u flag (for scripts that are in a module).

If you have complicated command line options then the cmdline.ss collection is recommended.
