sqlite-utils 2.14 (via) I finally figured out porter stemming with SQLite full-text search today—it turns out it’s as easy as adding tokenize=’porter’ to the CREATE VIRTUAL TABLE statement. So I just shipped sqlite-utils 2.14 with a tokenize= option (plus the ability to insert binary file data from stdin). # 1st August 2020, 9:19 pm

Fun with binary data and SQLite

This week I’ve been mainly experimenting with binary data storage in SQLite. sqlite-utils can now insert data from binary files, and datasette-media can serve content over HTTP that originated as binary BLOBs in a database file.

sqlite-utils 2.12 (via) I’ve been experimenting with ways of improving BLOB support in Datasette and sqlite-utils. This new version of sqlite-utils includes a “sqlite-utils insert-files” command, which can recursively crawl directories for files and add their contents to SQLite with configurable columns containing their metadata. I was inspired by Paul Ford who has been creating multi-GB SQLite databases of images and PDFs. It turns out that when disk space is cheap this is a pretty effective way of working with interesting corpuses of documents and images. # 27th July 2020, 7:36 am

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.

Weeknotes: this week was absurd

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.

Weeknotes: Python 3.7 on Glitch, datasette-render-markdown

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.

sqlite-utils 1.11. Amjith Ramanujam contributed an excellent new feature to sqlite-utils, which I’ve now released as part of version 1.11. Previously you could enable SQLite full-text-search on a table using the .enable_fts() method (or the “sqlite-utils enable-fts” CLI command) but it wouldn’t reflect future changes to the table—you had to use populate_fts() any time you inserted new records. Thanks to Amjith you can now pass create_triggers=True (or --create-triggers) to cause sqlite-utils to automatically add triggers that keeps the FTS index up-to-date any time a row is inserted, updated or deleted from the table. # 3rd September 2019, 1:05 am

Working with many-to-many relationships in sqlite-utils (via) I just released sqlite-utils 1.9 with syntactic sugar support for creating many-to-many relationships for records stored in SQLite databases. # 4th August 2019, 3:57 am

Convert Locations.kml (pulled from an iPhone backup) to SQLite. I’ve been playing around with data from my iPhone using the iPhone Backup Extractor app and one of the things it exports for you is a Locations.kml file full of location history data. I wrote a tiny script using Python’s ElementTree XMLPullParser to efficiently iterate through the Placemarks and yield them as dictionaries, which I then batch-inserted into sqlite-utils to create a SQLite database. # 14th June 2019, 12:45 am

paginate-json (via) I released a fun tiny utility: paginate-json, which knows how to paginate through JSON APIs that use the HTTP Link header for pagination. I built it so I could pull data from the GitHub API and pipe it directly into SQLite via sqlite-utils. # 12th June 2019, 3:22 pm

sqlite-utils 1.0. I just released sqlite-utils 1.0, with a couple of handy new features over 0.14: it can now automatically add columns to a database table if you attempt to insert data which doesn’t quite fit (using alter=True in the Python API or the --alter option to the “sqlite-utils insert” command). It also has the ability to output nested JSON column values on the command-line using the new --json-cols option. This is the first project I’ve marked as a 1.0 release in a very long time—I’ll be sticking to semver for this project from now on, bumping the major version only in the case of a backwards incompatible change. # 25th May 2019, 1:20 am
