act argument in add( ) subroutine

[wadudmiah]

Hello,

In your example code, there is an actual argument called "act" with a value "store":

call cli%add(switch='--string', &
switch_ab='-s', &
help='a string', &
required=.true., &
act='store', &
error=error)

What exactly is this argument for and what the possible values and their meanings?

Thanks in advance,
Wadud.

@wadudmiah Hi, I am not sure to follow your question.

The argument act is used to select the kind of CLA you are defining, e.g.:

• act='storemeans to store the value pased after the switch name, e.g.-s hellowill store the stringhello`;
• act='store_true' means that the switch doesn't require a value, but if passed the value .true. is automatically stored, e.g. -save could be an invocation of a switch to activate the saving of a file.

For more details about the definition of CLA refer to the wiki https://github.com/szaghi/FLAP/wiki/CLI-Method-add

Let me know if this help, or give me more details.

See you soon.

Moreover, the value stored can be of any kind: it is parsed as a string and returned on your demand with the type and kind you want, e.g. -i 65 will store 65 as a string, but with %get method you will obtain an integer, if you want.
