# 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` (>= 3.9) being installed.


```bash
pip install risset
```

This will install the script "risset" into your path


### Linux

In certain linux distributions it is not allowed to install packages to the
system python. In that case the recommended way is to install risset within
its own virtual environment. On ubuntu this can be done via `pipx`:

```bash
sudo apt install pipx
pipx install risset
```


# Quick start

```bash

# list all defined packages

$ risset list

    $ risset show <plugin>


### install

Install one or multiple plugins

    $ risset install [--force] <plugin> [<plugin2>, ...]

Install a given plugin for the current platform. Plugins are installed into
the user folder (no administrator requirements are needed). Look at the `info`
command to query information about the system.

    $ risset man [options] <opcode>


##### Options

# 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`
See one of the examples in https://github.com/csound-plugins/csound-plugins/tree/master/src for
more information about the manifest
