Add core.query/serialize?

Not sure if this is something you’d be interesting in having in the core here/in utils, is the leftover helper modules I created while maintaining my fork.

As I was writing HPI_API I added a core.serialize and core.query to my HPI fork as well.

It is quite magical (as it just resolves the function name with a string) but it lets me do some simple queries pretty easily, and play around with pipelines in the shell without having to worry about how to interop with python/dumping something from the REPL

https://github.com/seanbreckenridge/HPI/blob/master/my/utils/query.py https://github.com/seanbreckenridge/HPI/blob/master/my/utils/serialize.py

and then a script that exposes that info:

https://github.com/seanbreckenridge/HPI/blob/master/scripts/hpi_query

As some examples, 5 songs I listened to recently:

$ hpi_query my.mpv history | jq -r '.[] | .path' | grep -i 'music' | head -n 5
/home/sean/Music/Radiohead/1994 - The Bends/11 - Sulk.mp3
/home/sean/Music/Radiohead/1994 - The Bends/02 - The Bends.mp3
/home/sean/Music/Nujabes/Nujabes - Metaphorical Music (2003) [V0]/10. Next View.mp3
/home/sean/Music/Earth, Wind & Fire/Earth Wind And Fire - Greatest Hits - [MP3-V0]/16 - After The Love Has Gone.mp3
/home/sean/Music/Darren Korb/Darren Korb - Transistor Original Soundtrack[2013] (V0)/14 - Darren Korb - Apex Beat.mp3

I also use this in my menu bar, to print how many calories/water I’ve drank today:

Like:

#!/bin/bash
# how many water I've had today

((BLOCK_BUTTON == 3)) && notify-send "$("${REPOS}/HPI/scripts/water-recent")"

HPI_QUERY="${REPOS}/HPI/scripts/hpi_query"
{
	"${HPI_QUERY}" --days 1 'my.food' 'water' | jq -r '.[] | .glasses'
	echo 0
} | datamash sum 1

Have even had some fun creating graphs like this in the terminal:

hpi_query my.food food | jq -r '.[] | "\(.on)\t\(.calories)"' | datamash groupby 1 sum 2 | sort | termgraph | head

could probably remove the click/simplejson dependencies, they were just thrown in there because it was fast and I always have those installed anyways

Maybe query could be a subcommand on the hpi script? instead of installing it as a separate script

[seanbreckenridge]

Only remaining task for this issue is to create a CLI for query. to combine my.core.query.select and my.core.serialize.dumps, (and probably creating a couple helper functions in my.core.query to glue the two together)

I think I can implement that well enough in argparse for now, and the switch to click can be later

[seanbreckenridge]

classes are often ‘forwarded’ from the original modules

Ah right. Could also use a combination of all three of these approaches. The hook approach also seems fine, would just require looping over the (I assume top-level) dict in the module in default function.

Defining a hook in the source module seems a bit too hacky/magical, as my.core.serialize may need importlib machinery then?

Will try to implement
