Full Changelog: v2.22.0...v2.23.0

v2.22.0

Enhancements

• feat: return an ExprSyntaxError for invalid references that end in a dot (#692)

v2.21.0

Enhancements

• Introduce ParseTraversalPartial, which allows traversals that include the splat ([*]) index operator. (#673)
• ext/dynblock: Now accepts marked values in for_each, and will transfer those marks (as much as technically possible) to values in the generated blocks. (#679)

Bugs Fixed

• Expression evaluation will no longer panic if the splat operator is applied to an unknown value that has cty marks. (#678)

v2.20.1

Bugs Fixed

• Return ExprSyntaxError when an invalid namespaced function is encountered during parsing (#668)

Internal

• Standardize on only two value dumping/diffing libraries (#669)

v2.20.0

v2.19.1

What's Changed

• hcldec must use WithoutOptionalAttributesDeep by @jbardin in #635

Full Changelog: v2.19.0...v2.19.1

v2.18.1

Bugs Fixed

• hclsyntax: Conditional expressions will no longer panic when one or both of their results are "marked", as is the case for situations like how HashiCorp Terraform tracks its concept of "sensitive values". (#630)

v2.18.0

Enhancements

• HCL now uses the tables from Unicode 15 when performing string normalization and character segmentation. HCL was previously using the Unicode 13 tables.

  For calling applications where consistent Unicode support is important, consider also upgrading to Go 1.21 at the same time as adopting HCL v2.18.0 so that the standard library unicode tables (used for case folding, etc) will also be from Unicode 15.

v2.17.1

Enhancements

• hclsyntax: When evaluating string templates that have a long known constant prefix, HCL will truncate the known prefix to avoid creating excessively-large refinements. String prefix refinements are intended primarily for relatively-short fixed prefixes, such as https:// at the start of a URL known to use that scheme. (#617)
• ext/tryfunc: The "try" and "can" functions now handle unknown values slightly more precisely, and so can return known values in more situations when given expressions referring to unknown symbols. (#622)

Bugs Fixed

• ext/typeexpr: Will no longer try to refine unknown values of unknown type when dealing with a user-specified type constraint containing the any keyword, avoiding an incorrect panic at runtime. (#625)
• ext/typeexpr: Now correctly handles attempts to declare the same object type attribute multiple times by returning an error. Previously this could potentially panic by creating an incoherent internal state. (#624)
