Change value

Apache 2.0

Change the value of an HCL attribute while leaving its key intact. The new value replaces the whole existing expression, unless regex is enabled.

org.openrewrite.hcl.ChangeValue

Required

keyPathString

A JSONPath expression locating the attribute whose value to change.

valueString

The new value as an HCL expression. String values have to be quoted, e.g. "8.0", while true, 8, ["a", "b"] or var.engine_version are used as is. If regex is enabled, the replacement for the parts of the current value matching oldValue instead, keeping its quotes. Capturing groups can be used, e.g. db.t3.$1.

Optional

oldValueString

Only change the value if it matches the configured oldValue. It is compared to numbers, booleans and strings without interpolation, the latter without their quotes. Any other value, like a reference, is left unchanged when oldValue is set.

regexBoolean

DefaultTrueFalse

Default false. If enabled, oldValue will be interpreted as a Regular Expression, to replace only all parts that match the regex. Capturing group can be used in value.
