"Error Parsing Numerical Value" when using a number minus something

[mccartney]

The following code:

locals {
  one = 1
  two = 3 - one
}

fails with:

when running new HCLParser().parse() against it.

Using hcl4j 0.7.3

Does this work if you treat the one as a local var ... i.e. local.one instead?

[mccartney]

It fails with the same error message.

Just tried with the current master (24550a3)

	void "should handle variables referring to each other" () {
		given:
		def hcl = '''
locals {
  one = 1
  two = 3 - local.one
}
'''
		HCLParser parser = new HCLParser();
		when:
		def results  = parser.parse(hcl)
		then:
		results != null
	}

fails with:
