Detect out-of-order dates in the CLI version

[borfast]

In the CLI version, if the user passes two dates as arguments and the first date is after the second date, arrispwgen exits with an exception thrown by the library.

The CLI version should catch the exception and exit gracefully, telling the user what the problem was.

I think it should better dont exit at all but display error and ask user for retry

It's also a possibility, yes. I'm not sure if it's worth the extra effort, though. The difference is simply that if the program exits, the user has have to type "arrispwgen" again (besides the two dates, of course).

but when you say quit you mean the program completely quits which mean the terminal exists. Its better just to add a while loop saying while true then just retry must be like 10 more code lines you can always encapsulate all in a while loop i guess. 2016-12-13 11:09 GMT-05:00 Raúl Pedro Fernandes Santos < notifications@github.com>:

The terminal will only exit if you launch the program by double-clicking the script directly, which you normally will not do because it is installed in a "hard to reach" location and because you need to pass some arguments to it. Also, if the terminal exits when the program exits (making it implicit that you launched it via double-clicking), it means you didn't pass it any arguments, and thus the program will simply output the current day's password and exit, which means the terminal will also exit and you won't be able to see anything.

In summary: I may be missing something but I don't see a case where the program exiting after being used in a normal way would cause the terminal to exit.

Could you provide an example of such a situation?
