Aria2p

Command-line tool and Python library to interact with an aria2c daemon process through JSON-RPC.

Requirements

aria2p requires Python 3.6. To install Python 3.6, I recommend pyenv:

# install pyenv
git clone https://github.com/pyenv/pyenv ~/.pyenv

# setup pyenv (you should also put these two lines in .bashrc or similar)
export PATH="${HOME}/.pyenv/bin:${PATH}"
eval "$(pyenv init -)"

# install Python 3.6
pyenv install 3.6.7

# make it available globally
pyenv global system 3.6.7

Installation

With pip:

python3.6 -m pip install aria2p

With pipx:

# install pipx with the recommended method
curl https://raw.githubusercontent.com/cs01/pipx/master/get-pipx.py | python3

pipx install --python python3.6 aria2p

Usage (as a library)

This library is still a work in progress. Some things listed here might not be implemented yet.

import aria2p

# initialization, these are the default values
aria2 = aria2p.API(
    aria2p.JSONRPCClient(
        host="http://localhost",
        port=6800,
        secret=""
    )
)

# list downloads
downloads = aria2.get_downloads()

for download in downloads:
    print(download.name, download.download_speed)
    
# add downloads
magnet_uri = "magnet:?xt=urn:..."

download = aria2.add_magnet(magnet_uri)

Usage (command-line)

For now, the command-line tool can only call methods using the client. More options directly using the API will come later.

aria2p -m,--method METHOD_NAME [-p,--params PARAMS... | -j,--json-params JSON_STRING]

The METHOD_NAME can be the exact method name, or just the name without the prefix. It is case-insensitive, and dashes and underscores will be removed. The following are all equivalent:

• aria2.addUri
• aria2.adduri
• addUri
• ADDURI
• aria2.ADD-URI
• add_uri
• A-d_D-u_R-i (yes it's valid)
• A---R---I---A---2.a__d__d__u__r__i (I think you got it)
• and even more ugly forms...

Calling aria2p without any arguments will simply display the list of current downloads:

GID   STATUS  PROGRESS  NAME

There is no interactive mode yet, but you can use watch to see how the downloads progress:

watch -d -t -n1 aria2p

Examples

List all available methods. This example uses jq.

$ aria2p -m listmethods | jq
[
  "aria2.addUri",
  "aria2.addTorrent",
  "aria2.getPeers",
  "aria2.addMetalink",
  "aria2.remove",
  "aria2.pause",
  "aria2.forcePause",
  "aria2.pauseAll",
  "aria2.forcePauseAll",
  "aria2.unpause",
  "aria2.unpauseAll",
  "aria2.forceRemove",
  "aria2.changePosition",
  "aria2.tellStatus",
  "aria2.getUris",
  "aria2.getFiles",
  "aria2.getServers",
  "aria2.tellActive",
  "aria2.tellWaiting",
  "aria2.tellStopped",
  "aria2.getOption",
  "aria2.changeUri",
  "aria2.changeOption",
  "aria2.getGlobalOption",
  "aria2.changeGlobalOption",
  "aria2.purgeDownloadResult",
  "aria2.removeDownloadResult",
  "aria2.getVersion",
  "aria2.getSessionInfo",
  "aria2.shutdown",
  "aria2.forceShutdown",
  "aria2.getGlobalStat",
  "aria2.saveSession",
  "system.multicall",
  "system.listMethods",
  "system.listNotifications"
]

List the GIDs (identifiers) of all active downloads. Note that we must give the parameters as a JSON string.

$ aria2p -m tellactive -j '[["gid"]]'
[{"gid": "b686cad55029d4df"}, {"gid": "4b39a1ad8fd94e26"}, {"gid": "9d331cc4b287e5df"}, {"gid": "8c9de0df753a5195"}]

Pause a download using its GID. Note that when a single string argument is required, it can be passed directly with -p.

$ aria2p -m pause -p b686cad55029d4df
"b686cad55029d4df"

Add a download using magnet URIs. This example uses jq -r to remove the quotation marks around the result.

$ aria2p -m adduri -j '[["magnet:?xt=urn:..."]]' | jq -r
4b39a1ad8fd94e26f

Purge download results (remove completed downloads from the list).

$ aria2p -m purge_download_result
"OK"
