Cary_travelcommand

A Cary command which accepts as the body a series of "travel legs" in the form

lhr->dub 4-8 aug 2015 staying in Kilkenny, Ireland
dub->lhr 8 Aug 2015

The staying in clause is optional and Cary will attempt to use the destination of that leg as the overnight stay. It is fairly flexible on routing, but still makes mistakes. It attempts to return a travel estimate with leg travel costs based on a configurable set of estimators and daily lodging and other per diem costs based on DoD travel tables.

The airline travel costs are estimated via Google's QPX API, and requires a developer API key.

Requirements

Cary_travelcommand relies on cary_perdiemcommand to look up per diem tables. It also relies on jinja2 and pyparsing.

For the QPX estimator, the google API client is also required (google-api-python-client)

Configuration

In your Cary local_conf.py file, please include configuration similar to the following (this repeats some data such as the locstring and db from Cary_perdiemcommand. If TEMPLATE_PATH is omitted, the default templates from the module will be used.

QPX_API_KEY = "my_api_key"

from travel_costs import make_test_estimator, QPXCostEstimator
TRAVEL_CONFIG = dict(
    LOCSTRING_FILENAME=PERDIEM_CONFIG['LOCSTRING_FILENAME'],
    DB_FILENAME=PERDIEM_CONFIG['DB_FILENAME'],
    TEMPLATE_PATH="/home/vputz/cary/plugin_data/travel",  # optional!
    AIRPORT_DATA="/path/to/airports.csv",
    TRAIN_STATION_DATA="/path/to/train_locations.txt",
    cost_estimators=[QPXCostEstimator(QPX_API_KEY)]
