## OP_SCRIPT
A viewer and debugger of Bitcoin scripts. **Early development.**
## Features
1. Can fetch transactions from:
1. A Bitcoin node (requires a full node with `txindex=1`). Default.
1. [Blockstream.info](https://blockstream.info) JSON API. Use `--blockstream` flag.
1. Automatically finds related output.
1. Allows to navigate forward and backward.
1. Shows stack per line of code.
1. Shows opcodes information (hex code, input, output, and description).
1. Supports witness data (SegWit).
1. Uses [`btcd/txscript`](https://github.com/btcsuite/btcd/tree/master/txscript) under the hood.
## Usage
1. `go get github.com/Jeiwan/opscript`
1. `opscript help`
```shell
Usage:
opscript [flags] transactionHash:inputIndex
opscript [command]
Available Commands:
buildspec
help Help about any command
Flags:
--blockstream Use blockstream.info API to get transactions.
-h, --help help for opscript
--node Use Bitcoin node to get transactions (requires 'txindex=1'). (default true)

* `q` – quit
* `↑`/`↓` – navigate between lines of code
## Examples
* Using Blockstream.info API:
```shell
opscript --blockstream 70fde4687efab8dae09737f87e30042030288fec42fd9e12f34c435cdeb7812c
```
* Specifying input index:
```shell
opscript --blockstream 70fde4687efab8dae09737f87e30042030288fec42fd9e12f34c435cdeb7812c:0
```
* Using a Bitcoin node:
```shell
opscript --rpc-user=woot --rpc-pass=woot 70fde4687efab8dae09737f87e30042030288fec42fd9e12f34c435cdeb7812c
