Advanced tools
This gem allows you to scrape stock exchange data from the following exchanges:
Install the gem and add to the application's Gemfile by executing:
$ bundle add rulethu_stock_exchange
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install rulethu_stock_exchange
** Make sure you have firefox browser installed **
Require the gem
require 'rulethu_stock_exchange'
Get the stock exchange. (Currently available stock exchanges are ZSE, JSE and LSE)
exchange = RulethuStockExchange::Exchanges::LSE
Create a Scraper passing in the url for the exchangew
scraper = RulethuStockExchange::Scraper.new exchange[:url]
Scrape the data passing in a selector
html = scraper.scrape exchange[:selector]
Create a parser to parse the data
parser = RulethuStockExchange::Parser.new html
Parse the data
data = parser.parse()
Write the data to JSON file
filename = RulethuStockExchange::IO.write_to_json_file data, 'lse'
Convert the JSON file to CSV
RulethuStockExchange::IO.json_to_csv filename
The CSV file is generated as follows
For Zimbabwe Stock Exchange, the procedure is the same as in the previous example except that the parsing method is different as shown below.
data = parser.parse_zse()
After checking out the repo, run bin/setup
