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 plugins.json, listing all available plugins. Each entry in the index has the form

{
    "plugins": {
        "myplugin@1.0.0": "plugins/<collection>/<version>/manifests/myplugin.json",
        "..." : "..."
    }
}

The path to the manifest is relative to the plugins.json file inside the git repository.

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

{
    "name": "name_of_the_plugin",
    "libname": "name_of_the_shared_library",
    "version": "major.minor.patch",
    "short_description": "a short description",
    "long_description": "a long description",
    "csound_version": "minimal_csound_version",
    "binaries": {
        "linux": {
            "url": "path_or_url_of_binary",
            "build_platform": "major.minor.patch",
            "extra_binaries": ["url1", "url2", "..."]
        },
        "macos": {
            "url": "...",
            "build_platform": "..."
        },
        "windows": "..."
    },
    "doc": "rel/path/to/docfolder",
    "opcodes": ["foo", "bar", "baz"],
    "author": "Plugin Author",
    "email": "[e-mail]",
    "repository": "https://url/to/were/the/source/is/developed"
}

Explanation of each term

In general, each field holding a url can be either a link or a path relative to the manifest itself.

• name: name of the plugin. For example, "chaoticoscils". This name must be unique
• libname: the name of the shared library, without extension (example: libchaoticoscils). This is used to check if the plugin is installed.
• 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 path to the shared binary itself (relative to the manifest), or a downloadable url pointing to the shared library. At the moment only path are supported
  • extra_binaries: an optional field holding an array of other binaries needed
  • build_platform: a string identifying the platform used to build the binary
• doc: (optional) A relative path to the folder holding the man pages for the opcodes. Defaults to a folder named "doc" besides the manifest file
• 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

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.

TODO

• subcommand doc: show documentation about an opcode inside a plugin
