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

-
Extracting Details from Standard Scripts Demonstrates extracting information from a standard public key script.
-
Manually Signing a Transaction Output Demonstrates manually creating and signing a redeem transaction.
-
Counting Opcodes in Scripts Demonstrates creating a script tokenizer instance and using it to count the number of opcodes a script contains.
