A monitor for craigslist searches.

Project description

A monitor for craigslist searches.
*Does not work on Windows.

The craigslist monitor uses a command line interface to create web scrapers which monitor craigslist searches for new listings. A scraper monitoring a search will check periodically for new listings and output their details into a text file.

Commands/Flags

Manager

  • To list the names of all active scrapers: cmonitor manager -l
  • To quit the manager and all active scrapers: cmonitor manager -q
  • To stop an active scraper: cmonitor manager -s <scraper_name>

Add

  • If a listing contains words specified by –exclude-words, the scraper will not output the details of that listing: cmonitor add <scraper details> -e [words...]
  • If –renewals is used, the scraper will output the details of listings that have been renewed (off by default): cmonitor add <scraper details> -r
  • The two positive digits following –time-refresh are used with random.randrange to determine how long (in seconds) until the scraper checks for new listing (default is 60 and 180): cmonitor add <scraper details> -t 200 300
