lunchup v1.1.1

Lunchup

Lunchup is a tool to randomly generate lunchtime meetup groups withing a larger organization. Lunchup takes into account any number of "cohort" groups, weighting its output to mix up those cohorts as much as possible.

Installation

npm install -g lunchup

Usage

lunchup SIZE [CSV ...]

Lunchup takes all input CSVs (including STDIN) of names to Cohorts, emitting a new CSV of names to groups. With no Cohort data, this list is simply randomized.

For example, given the input:

Schoon, 200
Dave, 200
Jim, 100
Larry, 400
Fred, 300
Stephen, 300

You might see the following:

> lunchup 3 in.csv
Dave,0
Larry,0
Fred,0
Schoon,1
Stephen,1
Jim,1

Rolling groups

If lunchup is a tool you use repeatedly with the same input data, you can feed previous results into lunchup:

> lunchup 3 in.csv > week_1.csv
> lunchup 3 in.csv week_1.csv > week_2.csv

Or, more succinctly:

> ls | xargs -n 1 echo | sort -r -f # (Figure out today's week number)
> lunchup 3 *.csv > week_n.csv
