* DQS
[[file:dqs.jpg]]
~dqs~ is an unofficial CLI implementation of Matt Fitzgerald's [[http://www.racingweight.com/index.html][Diet Quality Score]] system, written in December 2019–January 2020. It is optimized for fast keyboard input and visual feedback in a terminal.
** Usage
#+begin_src shell
dqs [-dir PATH] [-d YYYYMMDD] [command] [arguments]
#+end_src
Flags:
- =-dir= — path to the data directory (default: =$XDG_CONFIG_HOME/dqs=)
- =-d=, =-date= — entry date in =YYYYMMDD= format (default: today)
** Commands
If no command is specified, ~dqs~ prints the entry for the date in use. On first run, ~dqs~ prompts to configure user settings.

| =remove= | =<category> <portions> [...]= | Remove portions from an entry |
| =weight= | =<weight>= | Set weight on the entry (and user profile if today) |

*** Examples
#+begin_src shell
# Add portions by category name (case-insensitive):
dqs add "Whole Grains" 1 dairy 2 fruit 1.5
# Add or remove portions using category abbreviations:
dqs add wg 1 d 2 nsh 0.5 f 1.5 v 2
dqs remove ff 0.5 s 1 o 2
# Record weight, body fat, or a note:
dqs weight 70
dqs body-fat 15.5
dqs note set "Post-run recovery"
# Log or delete an entry for a past date:
dqs -d 20200104 add v 2 lpp 1.5
dqs -d 20200104 delete
#+end_src
** Interpreting the Output
- A full portion is marked with a full-color background.
- A half-portion colors the portion's points, but not the background.
- Green marks portions with positive points, yellow for zero points, and red for negative points.
- The total DQS, weight, body fat, and BMI are printed below the portion table.
