Welcome to Apache Steve http://steve.apache.org/

Apache Steve is software to conduct a vote using the STV (Single Transferable Vote) and other voting algorithms. The tool grew out of the voting system used to elect the Apache Software Foundation Board of Directors.

Read more about STV at http://en.wikipedia.org/wiki/Single_transferable_vote

[!NOTE]

The v3 directory contains the current (ongoing) version of Steve. Read the v3/README.md file for more information about this version. Read the Getting Started Guide to set up a development environment for v3.

STV tally and what-if

Meek STV lives in monitoring/stv_tool.py. v3 tallies (steve.vtypes.stv) and the what-if CLI both call that module.

Load a vote file with LoadData.from_path (a file, not a directory):

Input	Behavior
vote-results.json (v3 tally JSON)	Source of truth. No warning.
raw_board_votes.txt (+ sibling board_nominations.ini)	Old-school. Warns on stderr.
raw_board_votes.json (v2 export)	Not a tally format. Warns and exits.

python3 monitoring/stv_tool.py path/to/vote-results.json
python3 monitoring/stv_tool.py -s 9 -v path/to/raw_board_votes.txt

What-if scenarios (seats, drop a candidate, runoff-only set) are whatif.py. The positional argv is fixed for whatif.rb:

python3 whatif.py [-v] VOTES_FILE [seats] [name ...]
python3 whatif.py VOTES_FILE -Lastname

Names may be first, last, or compacted full name (case-insensitive). A leading - on a name removes that candidate; otherwise only the named candidates run. Warnings for legacy files go to stderr so they do not break whatif.rb grepping of elected lines.

whatif.rb still consumes raw_board_votes.txt. Do not point it at v2 JSON. Prefer vote-results.json for new tallies.
