Datasette on Codespaces, sqlite-utils API reference documentation and other weeknotes
This week I broke my streak of not sending out the Datasette newsletter, figured out how to use Sphinx for Python class documentation, worked out how to run Datasette on GitHub Codespaces, implemented Datasette column metadata and got tantalizingly close to a solution for an elusive Datasette feature.
[... 2,164 words]Adding Sphinx autodoc to a project, and configuring Read The Docs to build it. My TIL notes from figuring out how to use sphinx-autodoc for the sqlite-utils reference documentation today.
sqlite-utils API reference (via) I released sqlite-utils 3.15.1 today with just one change, but it’s a big one: I’ve added docstrings and type annotations to nearly every method in the library, and I’ve started using sphinx-autodoc to generate an API reference page in the documentation directly from those docstrings. I’ve deliberately avoided building this kind of documentation in the past because I so often see projects where the class reference is the ONLY documentation, which I find makes it really hard to figure out how to actually use it. sqlite-utils already has extensive narrative prose documentation so in this case I think it’s a useful enhancement—especially since the docstrings and type hints can help improve the usability of the library in IDEs and Jupyter notebooks.
Everything new in Datasette since January, plus Django SQL Dashboard. I sent out the first Datasette newsletter since late January this year, covering everything that’s new in Datasette and sqlite-utils this year and introducing Django SQL Dashboard.
Apply conversion functions to data in SQLite columns with the sqlite-utils CLI tool
Earlier this week I released sqlite-utils 3.14 with a powerful new command-line tool: sqlite-utils convert, which applies a conversion function to data stored in a SQLite column.
Weeknotes: sqlite-utils updates, Datasette and asgi-csrf, open-sourcing VIAL
Some work on sqlite-utils, asgi-csrf, a Datasette alpha and we open-sourced VIAL.
Joining CSV and JSON data with an in-memory SQLite database
The new sqlite-utils memory command can import CSV and JSON data directly into an in-memory SQLite database, combine and query it using SQL and output the results as CSV, JSON or various other formats of plain text tables.
Weeknotes: New releases across nine different projects
A new release and security patch for Datasette, plus releases of sqlite-utils, datasette-auth-passwords, django-sql-dashboard, datasette-upload-csvs, xml-analyser, datasette-placekey, datasette-mask-columns and db-to-sqlite.
[... 861 words]Weeknotes: Docker architectures, sqlite-utils 3.7, nearly there with Datasette 0.57
This week I learned a whole bunch about using Docker to emulate different architectures, released sqlite-utils 3.7 and made a ton of progress towards the almost-ready-to-ship Datasette 0.57.
[... 1,081 words]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]sqlite-utils 3.2 (via) As discussed in my weeknotes yesterday, this is the release of sqlite-utils that adds the new “cached table counts via triggers” mechanism.
