Porting Datasette to ASGI, and Turtles all the way down
This evening I finally closed a Datasette issue that I opened more than 13 months ago: #272: Port Datasette to ASGI. A few notes on why this is such an important step for the project.
[... 1082 words]json-flatten. A little Python library I wrote that attempts to flatten a JSON object into a set of key/value pairs suitable for transmitting in a query string or using to construct an HTML form. I first wrote this back in 2015 as a Gist—I’ve reconstructed the Gist commit history in a new repository and shipped it to PyPI. # 22nd June 2019, 4:51 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
datasette-render-binary (via) Yet another tiny Datasette plugin. This one attempts to render binary data in a slightly more readable fashion—it shows ASCII characters as they are, and shows all other data as monospace octets. Useful as a tool for exploring new unfamiliar databases as it makes it easier to spot if a binary column may contain a decipherable binary format. # 9th June 2019, 4:22 pm
datasette-bplist (via) It turns out an OS X laptop is positively crammed with SQLite databases, and many of them contain values that are data structures encoded using Apple’s binary plist format. datasette-bplist is my new plugin to help explore those files: it provides a display hook for rendering their contents, and a custom bplist_to_json() SQL function which can be used to extract and query information that is embedded in those values. The README includes tips on how to pull interesting EXIF data out of the SQLite database that sits behind Apple Photos. # 9th June 2019, 1:26 am
