This separates the test code related to parsing scripts using the human-readable short form used throughout the tests into a separate file so it can more easily be copied into other packages where it might be useful for the tests as well. Allowing it to be copied is preferred to making it part of the public API of some package since it is an ad-hoc format and it is not possible to access test-specific code across package boundaries without making it part of the actual public API. |

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
This package is part of the github.com/decred/dcrd/txscript/v3 module. Use
the standard go tooling for working with modules to incorporate it.
Examples
-
Standard Pay-to-pubkey-hash Script Demonstrates creating a script which pays to a Decred address. It also prints the created script hex and uses the DisasmString function to display the disassembled script.
-
Extracting Details from Standard Scripts Demonstrates extracting information from a standard public key script.
-
Counting Opcodes in Scripts Demonstrates creating a script tokenizer instance and using it to count the number of opcodes a script contains.
