## Installation ## Installation
* Download the latest [release](https://github.com/BentonEdmondson/knock/releases). Make sure it is the correct version for your architecture (run `uname -m` to check). 1. Run `uname -ms` and, based on the output, download the latest corresponding [release](https://github.com/BentonEdmondson/knock/releases).
* Rename the binary and make it executable. 1. `cd` into the directory that knock is in (e.g. `cd ~/Downloads`).
* Run `knock /path/to/book.acsm` to perform the conversion. 1. Run `mv knock-version-arch-os knock` to rename the binary to `knock`.
1. Run `chmod +x knock` to make it executable.
1. Run `./knock ./path/to/book.acsm` to perform the conversion.
1. Run `mv knock ~/.local/bin` to allow it to be run from anywhere (might not work on some distributions).
### Nix and NixOS (with [flakes](https://nixos.wiki/wiki/Flakes) enabled)
If you are on a system with [Nix](https://github.com/NixOS/nix), you can use the following.
```
nix profile install github:BentonEdmondson/knock
```
If you are on [NixOS](https://github.com/NixOS/nixpkgs), you can add the flake to your system config.

## The Name
The name comes from the [D&D 5e spell](https://roll20.net/compendium/dnd5e/Knock#content) for freeing locked items:
> ### Knock
> *2nd level transmutation*\
> **Casting Time**: 1 action\
> **Range**: 60 feet\
> **Components**: V\
> **Duration**: Instantaneous\
> **Classes**: Bard, Sorcerer, Wizard\
> Choose an object that you can see within range. The object can be a door, a box, a chest, a set of manacles, a padlock, or another object that contains a mundane or magical means that prevents access. A target that is held shut by a mundane lock or that is stuck or barred becomes unlocked, unstuck, or unbarred. If the object has multiple locks, only one of them is unlocked. If you choose a target that is held shut with arcane lock, that spell is suppressed for 10 minutes, during which time the target can be opened and shut normally. When you cast the spell, a loud knock, audible from as far away as 300 feet, emanates from the target object.
