A web crawler in C++ which takes as input two cities and shows bus schedule between them.
It sends request to travelyaari.com and stores the response in Redis cache.

It can be used in the following two modes:

• A command line interface and,
  
• A webapp using codeIgniter MVC framework

• hiredis - C wrapper for Redis
  
• rapidjson - for parsing raw JSON repsonse

• crawl_cli.cpp - for command line interface.
  
• crawl_server.cpp - server for codeIgnitor MVC framework

• First install Redis server using the following command:
  sudo apt-get install redis-server

• Clone this repository:
  git clone https://github.com/prashkr/slink.git

• Run make install

• Run make compile

• Start redis server by typing redis-server on terminal.

• For command line interface
  ./crawl_cli <source_city> <destination_city>
e.g. ./crawl_cli Delhi Mumbai

• For Webapp

  • Copy codeIgnitor into your server folder so you can access the webapp on http://localhost
If you don't have a server running then you can use php to create a server
cd CodeIgniter-3.0.0
Run "php -S 127.0.0.1:80"
Now you can see the webapp on http://localhost
    
  • Run ./crawl_server so that server starts listening for request from Webapp.
