Weeknotes: airtable-export, generating screenshots in GitHub Actions, Dogsheep!

This week I figured out how to populate Datasette from Airtable, wrote code to generate social media preview card page screenshots using Puppeteer, and made a big breakthrough with my Dogsheep project.

airtable-export. I wrote a command-line utility for exporting data from Airtable and dumping it to disk as YAML, JSON or newline delimited JSON files. This means you can backup an Airtable database from a GitHub Action and get a commit history of changes made to your data. # 29th August 2020, 9:48 pm

More YAML

Paul Tchistopolskii’s XML Alternatives reminded me to take another look at YAML. The specification has been updated since I last looked and seems to be a bit more complicated, but it’s still a very nicely designed format. Implementations are available for Perl, Python and Ruby with C and Java on the way but strangely no one seems to be doing one for PHP yet. I’m doing a course at Uni on compilers at the moment which includes quite a lot of stuff about writing parsers so I’m very tempted to have a go at a YAML implementation in the next few weeks just to try stuff out. The possibility of easily swapping relatively complex data structures between PHP and Python is pretty tempting as well.

YAML

I forget quite how I got there, but the other day I found myself reading about YAMLYAML Ain’t Markup Language. It looks really interesting.

Where it differs from the IT world’s favourite buzzword is that YAML is specifically designed to handle the three most common data structures—scalars (single values), lists and dictionaries. Here’s a sample (taken from the official specification):
