crawler_detect.isCrawler('Mozilla/5.0 (compatible; Sosospider/2.0; +http://help.soso.com/webspider.htm)')
# true if crawler user agent detected
```

## Variant 2
```Python

crawler_detect.isCrawler()
# true if crawler user agent detected
```

## Variant 3
```Python
from crawlerdetect import CrawlerDetect
crawler_detect = CrawlerDetect(headers={'DOCUMENT_ROOT': '/home/test/public_html', 'GATEWAY_INTERFACE': 'CGI/1.1', 'HTTP_ACCEPT': '*/*', 'HTTP_ACCEPT_ENCODING': 'gzip, deflate', 'HTTP_CACHE_CONTROL': 'no-cache', 'HTTP_CONNECTION': 'Keep-Alive', 'HTTP_FROM': 'googlebot(at)googlebot.com', 'HTTP_HOST': 'www.test.com', 'HTTP_PRAGMA': 'no-cache', 'HTTP_USER_AGENT': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.71 Safari/537.36', 'PATH': '/bin:/usr/bin', 'QUERY_STRING': 'order=closingDate', 'REDIRECT_STATUS': '200', 'REMOTE_ADDR': '127.0.0.1', 'REMOTE_PORT': '3360', 'REQUEST_METHOD': 'GET', 'REQUEST_URI': '/?test=testing', 'SCRIPT_FILENAME': '/home/test/public_html/index.php', 'SCRIPT_NAME': '/index.php', 'SERVER_ADDR': '127.0.0.1', 'SERVER_ADMIN': 'webmaster@test.com', 'SERVER_NAME': 'www.test.com', 'SERVER_PORT': '80', 'SERVER_PROTOCOL': 'HTTP/1.1', 'SERVER_SIGNATURE': '', 'SERVER_SOFTWARE': 'Apache', 'UNIQUE_ID': 'Vx6MENRxerBUSDEQgFLAAAAAS', 'PHP_SELF': '/index.php', 'REQUEST_TIME_FLOAT': 1461619728.0705, 'REQUEST_TIME': 1461619728})

## Output the name of the bot that matched (if any)
```Python
from crawlerdetect import CrawlerDetect
crawler_detect = CrawlerDetect()
crawler_detect.isCrawler('Mozilla/5.0 (compatible; Sosospider/2.0; +http://help.soso.com/webspider.htm)')
# true if crawler user agent detected
crawler_detect.getMatches()
# Sosospider
```

## Get version of the library
```Python
import crawlerdetect
crawlerdetect.__version__
```

# Contributing

The patterns and testcases are synced from the PHP repo. If you find a bot/spider/crawler user agent that crawlerdetect fails to detect, please submit a pull request with the regex pattern and a testcase to the [upstream PHP repo](https://github.com/JayBizzle/Crawler-Detect).

Failing that, just create an issue with the user agent you have found, and we'll take it from there :)
