This cleans up the code for handling the right opcode to explicitly call out its semantics which are likely not otherwise obvious as well as improve its readability. It also adds several tests to the reference script tests which exercise the semantics of the right opcode including both positive and negative tests. |

txscript
Package txscript implements the Decred transaction script language. There is a comprehensive test suite.
This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate Decred transaction scripts.
Decred Scripts
Decred provides a stack-based, FORTH-like language for the scripts in the Decred transactions. This language is not turing complete although it is still fairly powerful.
Installation and Updating
$ go get -u github.com/decred/dcrd/txscript
