# risset: a package manager for csound

This is the repository of risset, a package manager for csound external
plugins and user-defined-opcodes. The index aggregating all available packages is kept 
at [risset-data](https://github.com/csound-plugins/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:

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

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

# Quick start

```bash
# list all defined packages
$ risset list

# Contributing

In order to add/modify a plugin, clone [risset-data](https://github.com/csound-plugins/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

```json
{
    "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
is always `risset.json`

#### Example of a manifest for a plugin

```json
{
  "name": "else",
  "version": "1.10.0",  
  "opcodes": [
    "accum",
    "atstop",
    "bisect",
    "crackle",
	...
  ],
  "short_description": "Miscellaneous plugins",
  "long_description": "Collection of miscellaneous plugins",
  "csound_version": "6.16",
  "author": "Eduardo Moguillansky",
  "email": "eduardo.moguillansky@gmail.com",

  "binaries": {
    "linux": {
      "url": "https://github.com/csound-plugins/csound-plugins/releases/download/v1.10.0/csound-plugins--linux.zip",
      "extractpath": "libelse.so",
      "build_platform": "Ubuntu 18.04"
    },

	  "extractpath": "libelse.dylib",
      "build_platform": "10.14.0"
    },
    "windows": {
      "url": "https://github.com/csound-plugins/csound-plugins/releases/download/v1.10.0/csound-plugins--win64.zip",
	  "extractpath": "libelse.dll",
      "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.
