Command-line tools that fetch a user's listening history from last.fm and perform analysis on it (e.g. what was I listening to last October?).

Usage

First, run update to fetch data from last.fm. This data is stored in a local SQLite database. Then, you can run the analysis commands top-artists and top-albums to get the top artists and albums for a given time period. Usage for these commands looks like:

$ last-fm-tools top-artists 2020-01 --user=foo
$ last-fm-tools top-albums 2020-01-01 2020-02-01 --user=foo --number=20

Configuration

Configuration options

• api_key and secret come from [https://www.last.fm/api/account/create]. Note that last.fm doesn't save these values, so you'll need to put them somewhere safe (e.g. the config file mentioned below, or a password manager).
• user is the last.fm username.
• database is the path to the sqlite database file.
• sendgrid_api_key (optional) is the API key for SendGrid, used for sending email reports
• from (optional) is the email address to send reports from

These may be specified either as normal flags, or as configuration options in $HOME/.last-fm-tools.yaml, forex:

database: "$HOME/lastfm.db"
api_key: ""
secret: ""
sendgrid_api_key: ""
from: "me@me.com"

Building

This project uses bazel for building. It's the only required dependency. To build and run directly using Bazel:

$ bazel run //:last-fm-tools -- update --user=foo --database=$HOME/lastfm.db

To run tests:

$ bazel test //...

Updating dependencies

To update dependencies edit [go.mod], and then run Gazelle:

bazel run //:gazelle -- update-repos -from_file=go.mod -to_macro=repositories.bzl%go_repositories
bazel run //:gazelle
