zrtool 0.1.0

CLI tool to deal with ZoomR16 project

zrtool

zrtool is a little cli tool that let you do some actions on a ZoomR16 project. For now, you can backup a project in a compressed format, and extract any data you need from it. You can also get the original uncompressed project if you want to restore a backuped project into you ZoomR16 device.

Installation

zrtool need a proper installation of flac (https://www.xiph.org/flac/) to work. The flac encoder and decoder is available on most platform, e.g. apt install flac for debian based OS.

zrtool will try to use the flac command line. If the flac binary is not accessible from your PATH, it can be specified with the ZRTOOL_FLAC_BIN environnement.

The recommended way to install zrtool is by using pipx:

pipx install zrtool

If you don't want to install pipx to manage python cli tools installation, zrtool can also be installed with pip:

pip install zrtool

Usage example

All this options are not yet available. They will be included in version 1.0.0. To see what's already implemented refer to the CHANGES document.

Backup a project under the zrpa format.

$ zrtool archive [--compress|--no-compress] PRJ000/ project-000.zrpa

Convert back to the original format.

$ zrtool export [--number N] project-000.zrpa [foo/]

It will create a directory PROJ000 in the foo directory. If foo is not specified, create PROJ000 in the current directory. Number is optional, if not given the number of the project is determined by the project that can be found in the target directory. If specified this number is used to define the name of the project directory.

    [--not] \
    --zprop "name" "Test" \
    --zprop-track "fader" 80 1 \
    --tag "title" ".*song" \
    --tag-file "title" ".*song" "MONO-000" \
