Input data

dot-maker uses two types of input:

• prompt: where the user has to enter some data and press Enter
• confirm: where the user has to enter one of the predefined options and/or press Enter

Prompt

The user is presented with a message, for example:

Input file name:

and they must enter some data and press Enter.

Whether the command accepts blank input depends on the command. Some will accept blank input and exit, others will keep prompting until the user enters some valid data.

Confirm

Confirmations are case-insensitive, so the user may enter lowercase, uppercase or mixed-case letters.

The user is presented with a message, for example:

Perform an action? [Y(es)/n(o)]:

OR

Perform an action? [y(es)/N(o)]:

and they must enter one of the predefined options and/or press Enter.

The valid options are: y, yes, n, no and blank. If the user enters an invalid value, the command will loop until it receives a valid input.

If the user submits a blank input, the default value is used. The default value can be identified by finding the branch starting with a capital letter. So, for [Y(es)/n(o)] the default value is yes and for [y(es)/N(o)] the default value is no.
