Examples

Login

Simply call pycaching.login() method and it will do everything for you.

import pycaching
geocaching = pycaching.login("user", "pass")

If you won’t provide an username or password, pycaching will try to load .gc_credentials file from current directory or home folder. It will try to parse it as JSON and use the keys username and password from that file as login credentials.

# sample .gc_credentials JSON file
{ "username": "myusername", "password": "mypassword" }

You can also provide multiple username and password tuples in a file as login credentials. The tuple to be used can be chosen by providing its username when calling pycaching.login(), e.g. pycaching.login("myusername2"). The first username and password tuple specified will be used as default if pycaching.login() is called without providing a username.

# sample .gc_credentials JSON file with mutiple users
[ { "username": "myusername1", "password": "mypassword1" },
  { "username": "myusername2", "password": "mypassword2" } ]

import pycaching
geocaching = pycaching.login()  # assume the .gc_credentials file is presented

In case you have a password manager in place featuring a command line interface (e.g. GNU pass) you may specify a password retrieval command using the password_cmd key instead of password.

# sample .gc_credentials JSON file with password command
{ "username": "myusername", "password_cmd": "pass geocaching.com/myUsername" }

Note that the password and password_cmd keys are mutually exclusive.

Load a cache details

cache = geocaching.get_cache("GC1PAR2")
print(cache.name)  # cache.load() is automatically called
print(cache.location)  # stored in cache, printed immediately

This uses lazy loading, so the Cache object is created immediately and the page is loaded when needed (accessing the name).

You can use a different method of loading cache details. It will be much faster, but it will load less details:

cache = geocaching.get_cache("GC1PAR2")
cache.load_quick()  # takes a small while
print(cache.name)  # stored in cache, printed immediately
print(cache.location)  # NOT stored in cache, will trigger full loading

You can also load a logbook for cache:

for log in cache.load_logbook(limit=200):
    print(log.visited, log.type, log.author, log.text)

Or its trackables:

for trackable in cache.load_trackables(limit=5):
    print(trackable.name)

Post a log to cache

geocaching.post_log("GC1PAR2", "Found cache in the rain. Nice place, TFTC!")

It is also possible to call post_log on Cache object, but you would have to create Log object manually and pass it to this method.

Search for all traditional caches around

from pycaching import Point
from pycaching.cache import Type

point = Point(56.25263, 15.26738)

for cache in geocaching.search(point, limit=50):
    if cache.type == Type.traditional:
        print(cache.name)

Notice the limit in the search function. It is because geocaching.search() returns a generator object, which would fetch the caches forever in case of a simple loop.

Geocode adress and search around

point = geocaching.geocode("Prague")

for cache in geocaching.search(point, limit=10):
    print(cache.name)

Find caches with their approximate locations in some area

Warning

This is currently not working because of this issue. Contributions are very welcome!

from pycaching import Point, Rectangle

rect = Rectangle(Point(60.15, 24.95), Point(60.17, 25.00))

for cache in geocaching.search_quick(rect, strict=True):
    print(cache.name, cache.location.precision)

Load trackable details

trackable = geocaching.get_trackable("TB3ZGT2")
print(trackable.name, trackable.goal, trackable.description, trackable.location)

Post a log for trackable

from pycaching.log import Log, Type as LogType
import datetime

log = Log(type=LogType.discovered_it, text="Nice TB!", visited=datetime.date.today())
tracking_code = "ABCDEF"
trackable.post_log(log, tracking_code)

Get geocaches by log type

from pycaching.log import Type as LogType

for find in geocaching.my_finds(limit=5):
    print(find.name)

for dnf in geocaching.my_dnfs(limit=2):
    print(dnf.name)

for note in geocaching.my_logs(LogType.note, limit=6):
    print(note.name)

Testing

Pycaching uses Betamax for testing, which speeds it up by recording network requests so that they can be mocked.

If you haven’t written or modified any tests, tests can be run like so:

python3 setup.py test

If you have written or modified tests, you must provide a username and password for testing. Don’t worry, these will not leave your computer. Betamax will insert a placeholder when it records any new cassettes. To run new tests, first set up the following environment variables:

PYCACHING_TEST_USERNAME="yourusername" PYCACHING_TEST_PASSWORD="yourpassword" python3 setup.py test

Substitute your username for yourusername and your password for yourpassword. After you have exported the environment variables once, you do not need to export them again, and can run tests with just python3 setup.py test.

To re-record a specific cassette in case of site changes, delete the corresponding JSON file and provide username and password as explained above. The missing cassette will be recorded for future usages.

Legal notice

Be sure to read Geocaching.com’s terms of use. By using this piece of software you break them and your Geocaching account may be suspended or even deleted. To prevent this, I recommend you to load the data you really need, nothing more. This software is provided “as is” and I am not responsible for any damage possibly caused by it.

Inspiration

Original version was inspired by these packages:

• Geocache Grabber (by Fuad Tabba)

• geocaching-py (by Lev Shamardin)

Although the new version was massively rewritten, I’d like to thank to their authors.
