This updates the data driven transaction script tests to combine the previously separate valid and invalid test data files into a single file and adds a field for the expected result. This is a nice improvement since it means tests can now ensure script failures are due to a specific expected reason as opposed to only generically detecting failure as the previous format required. Since it is possible that the script engine might return more fine grained errors than that test data expects, the test adapter handles this by allowing expected errors in the test data to be mapped to multiple txscript errors. While performing the conversion, it also adds several tests for the following areas: - The test harness itself to ensure the parsing logic, particularly for the recently added repetition syntax, is working as intended - All of the opcodes which were converted to NOPs in Decred to ensure they are also discouraged from use - All of the reserved opcodes in Decred |

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
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. -
Manually Signing a Transaction Output
Demonstrates manually creating and signing a redeem transaction.
