Isop infers parameters

21 Sep 2013

Command line tools should do what people expect. It’s a bit chaotic to navigate how to parse command line parameters since there are many conventions.

• A single - to indicate a short parameter, that is: -a
• Two – to indicate a long parameter, that is: –alpha
• A single / to indicate a parameter, that is: /alpha
• A single - to indicate a parameter, that is: -alpha
• A parameter followed by a space and then a value for that parameter: /alpha value
• A parameter followed by a = and then a value for that parameter: –alpha=value
• The position of the parameter (the ordinal position) to indicate simply a value

I’ve added code to try to infer value for a parameter using it’s ordinal position when there are no ordinary parameters present before the inferred parameter value.

This simply means that it should be possible to write:

my.exe --param1=something --param2=someother

and also:

my.exe something someother
