pycmc 0.0.11

pycmc Python Chartmetric Client

A Python client for the Chartmetric API. Query artists, their music,
and where their fans listen, by Musicfox.
And do it all in Python.
Installation
We highly recommend you install pycmc
into some type of virtual environment.
Then you should use pip or the like:
pip install pycmc

or
pipenv install pycmc # latest release


Using Pipenv you may need to pin the version, unless you allow for pre-releases. We don't have a beta or alpha qualifier but view this software
as such.

And don't forget you need an API subscription and subsequently, auth keys for Chartmetric -- see below.

⚠ Remember: You're not done yet; you'll need to set an authentication environment variable for queries.

Quick start
If you're already setup with your environment variable, you can query Rihanna's metadata with a quick call to the artist module:
>>> import pycmc
>>> rihanna_metadata = pycmc.artist.metadata(cmid=2316)

Yep, it's that simple.

"You should remember that it's peace of mind you're after and not just a fixed machine."
-- Robert Pirsig, via Phaedrus

Authentication
Chartmetric requires an authorization process to query their API. You can
see their docs here.
Add the CMCREDENTIALS environment variable
For pycmc you need to set a single
environment variable, CMCREDENTIALS, to equal your JSON authentication string of the following:
{
"token":"",
"scope":"",
"expires_in":"",
"refreshtoken":"your-chartmetric-token-here",
}


🔎 Be sure the above is a string when you set your environment variable.

How to set up pycmc authentication

Save the JSON file above to disk and note the absolute directory.
Using your absolute directory below,

# REQUIRED - Set your environment variable
export CMCREDENTIALS=$(cat path/to/credentials/file.json)
# OPTIONAL - Remove the .json file you created
rm -rf path/to/credentials/file.json

Design
To somewhat follow the API design of chartmetric and make our lives easier here,
we'll roughly adhere to the following module design where the pycmc package
contains the following modules:

album
artist
charts
curator
playlist
track
credentials
credentials_manager
utilities

Each module above provides (most) methods for a specific endpoint
to the chartmetric.com API, (mostly) labelled as their GET endpoints.
For example,
>>> 'API ALBUM META URL' = 'https://api.charmetric.io/api/album/:id'

Album Metadata
To get an album's metadata just call the metadata function:
>>> import pycmc
>>> pycmc.album.metadata('chartmetricID') # return dict of album metatdata

Spotify top charts
Obviously we'll start with the elephant in the room and get the top
charts from Spotify.
What was the US jamming to on the first day of the new year?
>>> cstracks = pycmc.charts.spotify.tracks(date='2019-01-01', )

Apple Music videos charts
What videos are charting in Apple Music on the same day as above?
>>> applemusic_vcharts = pycmc.charts.itunes.videos(date='2019-01-01')

Track metatdata
Let's get some metadata on the track Believe It by PARTYNEXTDOOR and Rihanna:
>>> believe_it = pycmc.track.metadata(cmid='28856569', )

Reference Documentation
We have hosted documentation over at our docs site
pycmc.docs.musicfox.io, which review the many endpoints offered by
the Chartmetric API.

pycmc development
Environment setup

Create an .env file in the application directory: touch pycmc/.env and populate with:
export CMCREDENTIALS="your-key"


Jump into your dev shell:
pipenv shell


And populate your environment:
source pycmc/.env



🎉 🎸 You're ready to rock! 🎸 🎉
Running the test suite
You'll obviously need to have an API key for Chartmetric to run tests.

ℹ️ The test suite is slowed to ~6s per request to the Chartmetric
API to protect production usage of the same keys, likely an issue (which we've handled herein) since
the API is rate limited.️

Run tests
pytest --cov=pycmc tests

Upload to the coverage tracker manually
First, DM @thinkjrs for the codecov token, which you'll need
to set below.
Coverage is typically updated automagically but if you need to manually generate the coverage on
https://codecov.io/gh/musicfox/pycmc, run:
export CODECOV_TOKEN="token-from-@thinkjrs"
./upload_coverage.bash

from your bash shell after running tests.
CI/CD on GCP
pycmc has a runner that builds a Python container, runs tests, and builds
the documentation site when new commits are pushed. As of December 2020 this is private
within the Musicfox Google Cloud Platform account.
Currently, you can track these builds in the action platform after you've been
given access to the repo.

Coming soon! We are planning to migrate to another
solution in the near future along with full tox-support (multiple python package build tests).
