terraform-docs version constraints is almost identical to the syntax used by Terraform. A version constraint is a string literal containing one or more condition, which are separated by commas.
Each condition consists of an operator and a version number. A version number is
a series of numbers separated by dots (e.g.
0.13.0). Note that version number
should not have leading
v in it.
Valid operators are as follow:
=(or no operator): allows for exact version number.
!=: exclude an exact version number.
<=: comparisons against a specific version.
~>: only the rightmost version component to increment.
Available options with their default values.
Only allow terraform-docs version between
version: ">= 0.13.0, < 1.0.0"
