cmdargs

cmdargs copied to clipboard

Say I have command line arguments, and one of the things that I want to accept is a list of arguments. Let's just use the example from here: https://zuttobenkyou.wordpress.com/2011/04/19/haskell-using-cmdargs-single-and-multi-mode/ So,...

Using `&= help` with `&= argPos` throws an error

expandArgsAt doesn't understand ~

1

expandArgsAt and @ARGSFILE seems a great feature, which I've enabled in hledger 1.4. I notice that @~/some/file doesn't work though, you have to write @$HOME/some/file instead. Perhaps there is some...
