There has been a lot of activity around Juice Calculators recently. And I've been scratching an itch of my own. It's the end of a long weekend of hacking about but it's ready for at least a demo and requests for comments.

It's a command line tool, using arguments and files and terminals and such. This quickmix is a bit untested, both it and ejmu are quick frontends to the backend calculation engine and may be slightly unforgiving.

$ ./quickmix \
  n 'Pluid Clone' \
  f 'Absinthe (TFA)' 12 \
  f 'Kiwi Double (TFA)' 8 \
  f 'Ecto Cooler (FW)' 2 \
  f 'Sweetener (TFA)' 2 \
  nic 18 100 \
  r vg 30 pg 100 \
  s 10

There's also an eJuice Me Up reader, ATM it doesn't use the mixing information from the .rec files, it just uses the flavor information. But that's easily changed. It's hard coded to my 18mg 70/30 PG/VG 10ml preferences.

$ ./ejmu rec/TinasNYCheesecakeStrawberriesCream.rec

The EJMU engine can also write out EJMU files (to a certain extent), It does have the ability to read in the older version of the .rec files and clean them up by moving comments in the flavor fields into the notes section.

The calculation engine supports a bunch of things not really shown here. Any flavor/nic can have any components of any ratio that can count towards the total volume or not, so it will handle PGA, DW, ACV, ... The final output is rather pluggable so there could be a variety of possibilities (HTML, PDF, D3, ...).

I haven't decided on a canonical recipe format, but it should be flexible enough to handle about anything. And it is missing a few things just because I haven't gotten around to them yet. I want to add more metadata (author, url, notes, ...)

So, what do you think? Does anybody else have a hankering for a command line utility like juice calculation engine?
