risset: a package manager for csound

This is the repository of risset, a package manager for csound external plugins and user-defined-opcodes. Plugin binaries and documentation is kept in a separate repository at risset-data

Installation

risset depends only on git and python3 (>= 3.7) being installed. For linux this is already the case, for macos and windows both need to be installed.

pip3 install risset

or via git:

git clone https://github.com/csound-plugins/risset
cd risset
python3 setup.py install

These commands will install the script "risset" into your path.

Contributing

In order to add/modify a plugin, clone risset-data

At the root of the repository there is an index file rissetindex.json, listing all available plugins. Each entry in the index has the form

{
    "version": "1.0.0",
    "plugins": {
        "else": {
            "url": "https://github.com/csound-plugins/csound-plugins.git",
            "path": "src/else"
        },
        "pathtools": {
            "url": "https://github.com/csound-plugins/csound-plugins.git",
            "path": "src/pathtools"
        },
        "klib": {
            "url": "https://github.com/csound-plugins/csound-plugins.git",
            "path": "src/klib"
        },
        "beosc": {
            "url": "https://github.com/csound-plugins/csound-plugins.git",
            "path": "src/beosc"
        },
        "vst3": {
            "url": "https://github.com/csound-plugins/vst3-risset.git"
        }
    }
}

The url + optional path points to a risset.json manifest file

Manifest

Each plugin has an accompanying manifest in the .json format. The name of this file should correspond to the name of the plugin: "myplugin.json"

Example of a manifest for a plugin

      "build_platform": "Windows 10"
    }
  }
}

Explanation of each term

• name: name of the plugin. This name must be unique
• version: a version string indicating the version of these binaries. The version should have the form "MAYOR.MINOR.PATCH" or "MAJOR.MINOR", where each term is an integer
• short_description: "A series of chaotic oscillators / noise generators"
• long_description (optional): "A longer description of what these opcodes do"
• csound_version: The minimal version of csound needed to run these opcodes. Example "6.14.0" (a string)
• binaries: A dictionary with platforms as keys. Possible platforms: "linux", "macos", "windows". The value for each entry should be itself a dictionary of the form:
  • url: the url where to download the plugin. Can point to a zip file.
  • extractpath: for the case when the url points to a compressed file, this field indicates whcat should be extracted from the compressed file
  • build_platform: a string identifying the platform used to build the binary
• opcodes: A list of all opcodes included in this plugin (for documentation purposes)
• author: The name of the author / mainteiner
• email: email of the author / mainteiner
• repository: the URL were the source code for this plugin is hosted, for reference

Platform support

It is desirable, but not a requirement, that all opcodes support the three major desktop platforms: linux, macos and windows. Support for a given platform is indicated by the availability of a binary for the given platform in the manifest.json file.
