A python module for pulling data from the Twitch.tv APIs (kraken, tmi, rechat).
pip install itch
Starting in August 2016, the kraken API will require an application client id.
If the environment variable TWITCH_CLIENT_ID
is set, itch will use this. There is no default value, but you can use the APIs without one until August;
after which you will have to supply your own.
itch models wrap their own API endpoints, so most items can be loaded by name using the static get
method, and used as dictionaries.
It'd be wise to familiarize yourself with the return values from the kraken v3 resources,
as most keys (like id
and name
) are not explicitly mentioned in the module, but read from json and made into a dict
.
>>> from itch.models import Channel >>> c = Channel.get('itmejp') >>> c.followers 248650 >>> c.created_at datetime.datetime(2010, 2, 28, 9, 30, 51)
All dates are made into timezone-absent datetime
instances. Nested objects are usually rolled into specialized classes of their own.
Lists of objects, where API paging is involved is done through generators, allowing you to seamlessly iterate over every item of a collection.

>>> for follow in c.list_following(): ... print follow.created_at, follow.channel.name ... 2011-03-04 03:16:19 giantbomb 2012-10-17 02:36:20 day9tv 2014-01-18 02:14:50 greenspeak 2014-01-20 00:50:58 towelliee 2014-07-16 05:42:50 camiwins 2014-07-28 23:31:00 incontroltv ... <snip>
Video objects can reprint chat, if the VOD is still available on twitch.tv .
>>> for video in c.past_streams(): ... for chatline in video.chat_replay(): ... print "[%s] %s: %s" % (video.id, chatline['from'], chatline.message) ... break ... break ... [v80935574] mwthecool: Hey everyone!
Channel
method get_chatters
can pull real-time chatters, moderators, and admins.
>>> map(str, c.get_chatters().moderators) ['crosseye_jack', 'gray_mask', 'itmebot', 'itmejp', 'reginaldxiv', 'strippin', 'tahkai11', 'zodiacviii']
Currently, only a file-based cache adapter is ready. Adapters for redis
and memcached
are planned for future releases.
Cache keys are the sha256
of URLs with query parameters, and the values are compressed responses.
To add a cache adapter, plug a CacheInterface
compliant subclass directly to the itch.TwitchAPI
before making requests.
from cache.filetree import FileTreeCache from itch import TwitchAPI TwitchAPI.set_caching(FileTreeCache())
The FileTreeCache
accepts the optional environment variable TWITCH_CACHE_TEMP
to set the cache path on disk.
rcache.RedisCache
requires the pip module redis
, which is not installed by itch. Starting with itch 0.3, the required modules can be installed by pip installing itch[cache]
or itch[complete]
.
This cache makes use the following environment variables:
REDIS_HOST (default: localhost) REDIS_PORT (default: 6379) REDIS_PASSWORD (default: '') REDIS_DB (default: 1)
mcache.MemcacheCache
requires the pip module python-memcached
, which is not installed by itch.
This cache makes use the MEMCACHE_SERVERS
environment variable, which should be a comma separated list
of <host>:<port>
items. The default value is 127.0.0.1:11211
.
Starting with itch 0.3, the required modules can be installed by pip installing itch[cache]
or itch[complete]
.
The command line tool prints tab-separated reports that are suitable for the plotter.
$ itch -h usage: itch [-h] [-d {asc,desc}] [-l LIMIT] [-c {file,redis,memcache}] [{chatlog,created,chatters,num_following,num_followers,followers,following,loots_streams}] [channel] Twitch.tv APIs module positional arguments: {chatlog,created,chatters,num_following,num_followers,followers,following,loots_streams} command channel channel optional arguments: -h, --help show this help message and exit -d {asc,desc}, --direction {asc,desc} sorting direction -l LIMIT, --limit LIMIT number of items to pull -c {file,redis,memcache}, --cache {file,redis,memcache} cache type. See README for required env vars
The cli tool itch-plot
renders charts with data extracted from the itch
CLI or other custom tools. The
module requires the pip modules matplotlib
and scipy
, which is not installed by itch (because numpy
).
Starting with itch 0.3, the required modules can be installed by pip installing itch[plot]
or itch[complete]
.
$ itch-plot -h usage: itch-plot [-h] [-x XFIELD] [-y YFIELD] [-m XMIN] [-M XMAX] [-n YMIN] [-N YMAX] [-d DELIMITER] [-r] [-s] [-S STREAMS] [-t {scatter,line,mixed}] [-l LABEL] [-T TITLE] [-D] [infile] [outfile] plot generator positional arguments: infile InFile outfile OutFile optional arguments: -h, --help show this help message and exit -x XFIELD X axis field name -y YFIELD Y axis field name -m XMIN, --xmin XMIN min x value -M XMAX, --xmax XMAX maz x value -n YMIN, --ymin YMIN yin x value -N YMAX, --ymax YMAX max y value -d DELIMITER, --delimiter DELIMITER field delimiter -r, --record print whole record (for saving subsets) -s, --silent skip printouts -S STREAMS, --streams STREAMS streams json -t {scatter,line,mixed}, --type {scatter,line,mixed} graph type -l LABEL, --label LABEL x label -T TITLE, --title TITLE chart title -D, --density Density coloration; much slower renders
Example data pull and chart render:
# dump the last 1K followers to a file itch -l 1000 -c file followers burkeblack > followers.csv # dump the last 20 streams to a file itch -l 20 -c file loots_streams burkeblack > streams.csv # plot the followers while overlaying the streams, # trimming the viewport and setting a title. itch-plot -sS streams.csv -m '2016-07-25' -M '2016-08-01' \ -T 'BurkeBlack - last 1K' followers.csv plot.png
Here is the resulting graph
Focused on my own use-cases, kraken v3 resources are not completely covered. This initial release of itch does not currently work with subscribers or subscriptions, games, or top stream lists.
