lazy programmer .. want to reduce the typing in a template

[jmls]

so, if I use a json file for input, the examples at https://docs.gomplate.ca/datasources/ show that I can use this format

However, if I have a template where the "name" is referred to in a dozen places, typing out

{{ $person.name }}

rather than

{{ (datasource "person").name }}

is quite appealing ;)

Is it possible to define a var at the top of the template that stores the (datasource "person") and which can then be used throughout the template ?

Sorry, don't know go templating at all, frantically trying to teach myself it ...

Apologies for the delayed response...

You can indeed define variables:

{{ $person := datasource "person" }}
Hello, {{ $person.name }}

Another approach is to use a context instead of a datasource, which removes the need to use the datasource function:

$ gomplate --context person=person.json -i 'Hello {{ .person.name }}'
