Configuring user name and email

When running the dtool interactive readme the default name and email address are Your Name and you@example.com.

$ dtool readme interactive my_dataset
description [Dataset description]:
project [Project name]:
confidential [False]:
personally_identifiable_information [False]:
name [Your Name]:
email [you@example.com]:
username [olssont]:
creation_date [2017-12-14]:

These defaults can be configuring the user name and email address.

$ dtool config user name "Care A. Bout-Data"
Care A. Bout-Data
$ dtool config user email researcher@famous.uni.ac.uk
researcher@famous.uni.ac.uk

Rerunning the previous dtool readme interactive command now gives updated defaults when prompting for input.

$ dtool readme interactive my_dataset
description [Dataset description]:
project [Project name]:
confidential [False]:
personally_identifiable_information [False]:
name [Care A. Bout-Data]:
email [researcher@famous.uni.ac.uk]:
