JSON formatting

[estahn]

The following will not pass YAML lint at the moment:

foo:
  bar: {{ `["foo", "bar"]` | json | toJSON }}

Expected Result:

foo:
  bar: ["foo", "bar"]

Actual Result:

foo:
  bar: ["foo","bar"]

I'm not sure what the issue is here - your listed "Actual" is valid YAML.

[estahn]

Yes, it's valid YAML according to the standard. We use YAML lint to check outputs and it complaints about the whitespace not existing:

Ok, I see. The purpose of the toJSON function is to marshal as JSON, and more specifically, as compact JSON (i.e. without any separating whitespace). The other option is to use toJSONPretty, but it would render the array across multiple lines:

$ gomplate -i '{{ `["foo", "bar"]` | jsonArray | toJSONPretty "  " }}'
[
  "foo",
  "bar"
]

Other than that, gomplate simply isn't going to produce YAML that satisfies your particular linter.

@hairyhenderson Fair enough, although the linter it's neither mine nor particular :)

Ok, then instead of "your particular linter" read "the linter you're choosing to use, with its particular configuration" 😉
