Open Source Voting Results Reporter (ORR)

Build Status

Election results report generator (HTML/PDF/XLS)

See doc/ for a description of the orr application and how it can be used to create collections of html/pdf/xml/xls files from election data.

Following an election orr can be used to create results summary pages on election night, and detailed Statement of Vote reports with precinct detail on each contest.

This is an official project of San Francisco's Open Source Voting System Technical Advisory Committee (OSVTAC).

To install

  • Requires python version 3.6
$ pip install -e ./src

To run

For command-line help:

$ orr -h

For a small HTML example demonstrating much of the functionality:

$ orr -v --input-dir sampledata/minimal-test \
      --template-dir templates/demo-template \
      --extra-template templates/demo-template/extra \
      --output-subdir minimal-test

Then open _build/minimal-test/index.html in a browser. The example above includes:

  • 3 contests
  • 4 languages
  • a details page for each contest
  • a PDF "Statement of Vote"

This example can also be seen published on the web here:

The templates directory contains more sample Jinja2 templates.

See the doc directory for more info.

To run tests

The following runs the test suite, including an "end-to-end" test of a non-trivial template directory (the "demo-template" one):

$ python -m unittest discover orr

To run an individual test, e.g.:

$ python -m unittest orr orr.tests.test_utils.UtilsModuleTest.test_compute_percent

For available options for running tests:

$ python -m unittest -h

To update the end-to-end test

To regenerate the test expectation for the end-to-end test and see a diff with what is currently in source control:

$ ./scripts/

Docker (experimental)

$ orr-docker -h

To render a template directory to the build directory using Docker:

$ orr-docker --input-dir sampledata/minimal-test \
        --template-dir templates/demo-template \
        --extra-template templates/demo-template/extra \
        --output-subdir minimal-test

To run tests:

$ docker build -t orr . \
    && docker run --entrypoint python orr -m unittest discover orr

TODO: change the above to a bash script?


Work on this project started informally around the beginning of May 2018. The Open Source Voting System Technical Advisory Committee (OSVTAC) adopted it as an official project by unanimous vote at its June 14, 2018 meeting. The source code was first made public on June 18, 2018 under OSVTAC's GitHub account.

Note that because OSVTAC is an official meeting body of the City and County of San Francisco, members must follow San Francisco's Sunshine Ordinance and California's Brown Act. Thus, members are limited in the extent to which they can collaborate with one another outside of meetings.
