The PRQL[1] syntax is built around pipelines and works pretty well.

I added a similar "get results as you type" feature to the SQLite integration in the Logfile Navigator (lnav)[2]. When entering PRQL queries, the preview will show the results for the current and previous stages of the pipeline. When you move the cursor around, the previews update accordingly. I was waiting years for something like PRQL to implement this since doing it with regular SQL requires more knowledge of the syntax and I didn't want to go down that path.

If you want to get started with prql check out qstudio https://www.timestored.com/qstudio/prql-ide it allows running prql easily against mysql postgresql duckdb etc

there's a PRQL extension for duckdb:

Nice work! The TUI looks really sharp and I like the histogram on top. Going to play with this today.

TIL awk patterns can be more than just regexes and can be combined with boolean operators. I've written a bit of awk and never realized this.

There's a ton of overlap between "powerful stuff that's easy to write in (g)awk" and "powerful stuff that's trivial to write in perl", but I find awk to be succinct without losing readability.

The article makes it sound like it uses various command-line tools (bash/awk/head/tail) to process the logs. So, I imagine it's not a huge leap to extend support to using journalctl to do that work instead.

One small hitch I found is that this kind of tools are fixes in what to process, so for example I can't use them for structured logging. If it has an escape hatch where I can supply my own pipe (for example `process = 'vector ....'`) then it will be enough.

> the Wayfarers series starting with “The Long Way to a Small, Angry Planet” is maybe the best collection of before-bed reading I’ve ever found.

I agree wholeheartedly and do, in fact, read them in bed. I transitioned to the Wayfarers after souring on The Expanse (I enjoyed most parts of those books, but the black ooze is not for me). The low-stakes, slice-of-life content is more up my alley.

Not exactly Seattle, but the Bellevue library has a makerspace — https://kcls.org/bellevuemakerspace/

Oh nice, the access to a professional quality sewing machine is a cool feature. I do some hobby upholstery and using my homegamer Singer is a real limiting factor.

They most certainly can be null as can “this”.

Only after dereferencing a null pointer, which would be the actual problem, not the fact that some reference or this is null.

You cannot have a null reference unless you invoke undefined behavior first.

I followed these instructions and the main advantage for us is that it can send notifications to phones and google/alexa devices. I ended up switching the software to sinric.pro, though.

> I do wish there was support for switching formats so I could switch between different "views" over the same data, maybe it will be possible someday :)

I created https://github.com/tstack/lnav/issues/1274 to remember this
