Help packaging a python-based tool

[robinbowes]

I've packaged my python app jobhound, and I'm not entirely happy with how it installs. I seems to pull down a lot more dependencies than other brew formulae and takes a looong time to install.

This is what the install looks like:

The formula is here: https://github.com/yo61/homebrew-tap/blob/main/Formula/jobhound.rb

Am I doing something wrong, or is this expected behaviour?

[SMillerDev]

That is expected behaviour for a source build. If you made the tap using brew tap-new it also came with a workflow to automatically build binaries though, which would be much faster.

[robinbowes]

That sounds like the bit I'm missing. Where can I read more about that?

[robinbowes]

The answer was to use brew tap-new and build bottles, as documented at https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap

I'm now banging my head on the recently-added release cooldown feature.

But I'll deal with that separately.

[robinbowes]

Following up on this.

The bottle install takes under 1.5 secs vs the 115 seconds of the original src install!

That's a 76.7x speed up, a 98.7% reduction in installation time, nearly 2 orders of magnitude faster!

Thanks for pointing me in the right direction.

R.
