- integration testing
. --show should not display variable and expression values
. get value of variable --evaluate --variable
. --info that prints whole justfile
. run app with command line options and test full output (stderr and stdout)
. exercise all features and all command line options
. test that a few error messages are correct
. test full output
. underline problem token in error messages
- figure out argument passing:

enhancements:
- save result of commands in variables
- multi line strings
- raw strings
- iteration: {{x for x in y}}
- allow calling recipes in a justfile in a different directory:
. just ../foo # ../justfile:foo
