Description
Supports execution of multiple scripts chained together
Overview
Thanks for creating this project, I have found it quite nice to use recently in an educational context.
Made a very small addition that I have found useful, which just reads in multiple files concatenated together. This was nice for the question of "does script X unlock script Y". Figured I'd PR it in case it's useful for others!
Testing
Try writing up two scripts and execute them together
Ex.
Executing:
$ btcexec ./makes-eight.bs ./checks-equal-to-eight.bs Script in hex: 517693769376935887 Script size: 9 bytes -------------------------------------------------- Execution ended. Success: true Final stack: <01> Stats: ExecStats { max_nb_stack_items: 2, opcode_count: 0, start_validation_weight: 51, validation_weight: 51, } Time elapsed: 0msExecuting with --debug
