Cross-database queries in SQLite (and weeknotes)
I released Datasette 0.55 and sqlite-utils 3.6 this week with a common theme across both releases: supporting cross-database joins.
[... 720 words]Video introduction to Datasette and sqlite-utils
I put together a 17 minute video introduction to Datasette and sqlite-utils for FOSDEM 2021, showing how you can use Datasette to explore data, and demonstrating using the sqlite-utils command-line tool to convert a CSV file into a SQLite database, and then publish it using datasette publish. Here’s the video, plus annotated screen captures with further links and commentary.
Weeknotes: Mostly messing around with map tiles
Most of what I worked on this week was covered in Serving map tiles from SQLite with MBTiles and datasette-tiles. I built two new plugins: datasette-tiles for serving map tiles, and datasette-basemap which bundles map tiles for zoom levels 0-6 of OpenStreetMap. I also released download-tiles for downloading tiles and bundling them into an MBTiles database.
[... 350 words]Weeknotes: datasette-export-notebook, PyInstaller packaged Datasette, CBSAs
What a terrible week. I’ve found it hard to concentrate on anything substantial. In a mostly futile attempt to distract myself from doomscrolling I’ve mainly been building some experimental output plugins, fiddling with PyInstaller and messing around with shapefiles.
[... 732 words]Weeknotes: A flurry of not-quite-finished features
My Christmas present to myself this year was to allow myself to spend a week working on stuff I found interesting, rather than sticking to the most important things. This may have been a mistake: it’s left me with a flurry of interesting but not-quite-finished features.

Natalie and I decided to escape San Francisco for election week, and have been holed up in Fort Bragg on the Northern California coast. I’ve mostly been on vacation, but I did find time to make some significant changes to sqlite-utils. Plus notes on an exciting Git scraping project.
[... 603 words]Weeknotes: evernote-to-sqlite, Datasette Weekly, scrapers, csv-diff, sqlite-utils
This week I built evernote-to-sqlite (see Building an Evernote to SQLite exporter), launched the Datasette Weekly newsletter, worked on some scrapers and pushed out some small improvements to several other projects.
Building an Evernote to SQLite exporter
I’ve been using Evernote for over a decade, and I’ve long wanted to export my data from it so I can do interesting things with it.

This week I completed the Software Carpentry instructor training course, added two foundational features to sqlite-utils and learned how to compile modules for SQLite.
Refactoring databases with sqlite-utils extract
Yesterday I described the new sqlite-utils transform mechanism for applying SQLite table transformations that go beyond those supported by ALTER TABLE. The other new feature in sqlite-utils 2.20 builds on that capability to allow you to refactor a database table by extracting columns into separate tables. I’ve called it sqlite-utils extract.
Executing advanced ALTER TABLE operations in SQLite
SQLite’s ALTER TABLE has some significant limitations: it can’t drop columns (UPDATE: that was fixed in SQLite 3.35.0 in March 2021), it can’t alter NOT NULL status, it can’t change column types. Since I spend a lot of time with SQLite these days I’ve written some code to fix this—both from Python and as a command-line utility.

Two new Datasette plugins this week: datasette-copyable, helping users copy-and-paste data from Datasette into other places, and datasette-insert-api, providing a JSON API for inserting and updating data and creating tables.

As of this morning, San Francisco is in a legally mandated shelter-in-place. I can hardly remember what life was like seven days ago. It’s been a very long, very crazy week. This was not a great week for getting stuff done.

Streaks is really working well for me. I’m at 12 days of commits to Datasette, 16 posting a daily Niche Museum, 19 of actually reviewing my email inbox and 14 of guitar practice. I rewarded myself for that last one by purchasing an actual classical (as opposed to acoustic) guitar.
