A justfile containing recipes to help download, convert, rename, file and archive your audiobook collection.
The use of these recipes in intended for the sole purpose of maintaining a PERSONAL archive, and the resulting `.m4b` files should not be redistributed where doing so would violate your contract with the supplier of the original `.aax` and `.aaxc` files.
## Requirements
- [mise-en-place](https://mise.jdx.dev)
Mise will be used to install the other dependencies. If you don't want to use `mise`, then you need to install the following:
- [just](https://just.systems/)
- [audible-cli](https://github.com/mkb79/audible-cli) (recommended installation instuctions below)
- [fzf](https://github.com/junegunn/fzf)
- [jq](https://jqlang.github.io/jq/)
- [ffmpeg](https://ffmpeg.org)
- [refile-m4b](https://crates.io/crates/refile-m4b)
### Transitive Dependencies
For `refile-m4b` you will also need these libraries (or the equivalent for your OS):
- libtag1-dev
- libtagc0-dev
#### Debian
```shell
sudo apt install libtag1-dev libtagc0-dev
```
### Install `mise`
```shell
curl https://mise.run | sh
~/.local/bin/mise --version
```
### Install dependencies with `mise`
```shell
mise install
```
This will use the `.mise.toml` file to install all the required dependencies.
### Note on Installing `audible-cli` Manually
If you aren't using `mise` to install the `audible-cli` then note that the latest version (`v0.3.1`) doesn't work (at least for me), so I recommend using the latest version in the `master` branch.
## Usage
### Check prerequisites
Run the `doctor` recipe to verify prerequisites:
```shell
just doctor
```
e.g.:
```text
Verify required executables are on the path:
- OKAY : audible => ~/.local/share/mise/installs/pipx-mkb79-audible-cli/master/bin/audible
- OKAY : just => ~/.local/share/mise/installs/just/latest/bin/just
- OKAY : fzf => ~/.local/share/mise/installs/go-github-com-junegunn-fzf/latest/bin/fzf
- OKAY : jq => ~/.local/share/mise/installs/jq/latest/bin/jq
- OKAY : ffmpeg => ~/.local/share/mise/installs/ffmpeg/latest/bin/ffmpeg
- OKAY : refile-m4b => ~/.local/share/mise/installs/cargo-refile-m4b/latest/bin/refile-m4b
```
### Authenticate & Register
When prompted to name your profile, use the default: '`audible`'.
We use that name to locate the file `~/.audible/audible.json` when converting AAX files.
```shell
audible quickstart
audible activation-bytes
```
This will log in to you account, register a pseudo device in your account and store the details in `~/.audible/`.
### Fetch Library
Once you have bought a title or otherwise added to your account's library, you need to fetch a copy of the latest library list.
```shell
just fetch-library
```
This will create a new file `library-{date}.txt`, that contains a list of everything available in your account.
### Select, download and convert
The recommended workflow is to run the default recipe which will present you with a searchable list of your library.
From here you can select items to download by pressing `TAB` (for selecting mutliple titles), or `ENTER` to select just the one.
Once you have made your selection, the `.aax` and/or `.aaxc/.voucher` files will be downloaded, via a `./TEMP/` directory,
before being moved to either the `./AAX/` or `./AAXC/` directories.
Once downloaded they will be automatically converted to DRM free `.m4b` files in the `./M4B/` directory.
NOTE: After being converted the source files in the `./AAX/` and `./AAXC/` directories are deleted.
The files in `./M4B/` will then be refiled, by `refile-m4b`, into directories based on the author, series and title.
### Review
You are now free to rename and/or move the files to more closely fit your own prefered archival needs.
### Archive
Once you are happy you can run the '`archive`' recipe to move the files into your archive.
```shell
export AUDIOBOOK_ARCHIVE=/mnt/external/audio-books/
just archive
```
Set the `AUDIOBOOK_ARCHIVE` environment variable to the directory where you want your `.m4b` files to be stored.
NOTE: Once the files have been copied, the files in the `M4B` directory are deleted.
