Datasette: publish_subcommand hook + default plugins mechanism, used for publish heroku/now (via) I just landed a new plugin hook to Datasette master: publish_subcommand, which lets you define new publisher subcommands for the “datasette publish” CLI tool in addition to Heroku and Zeit Now. As part of this I’ve refactored the heroku/now publisher implementations into two default plugins that ship as part of Datasette—I hope to use this pattern for other core functionality in the future. # 26th July 2018, 5:27 am

datasette-vega (via) I wrote a visualization plugin for Datasette that uses the excellent Vega “visualization grammar” library to provide bar, line and scatter charts configurable against any Datasette table or SQL query. # 29th June 2018, 3 pm

Datasette 0.19: Plugins Documentation (via) I’ve released the first preview of Datasette’s new plugin support, which uses the pluggy package originally developed for py.test. So far the only two plugin hooks are for SQLite connection creation (allowing custom SQL functions to be registered) and Jinja2 template environment initialization (for custom template tags), but this release is mainly about exercising the plugin registration mechanism and starting to gather feedback. Lots more to come. # 17th April 2018, 3:59 am
