I'm thinking of building an automated trading system.I think there's probably no services supplying informations of order book and top of book in the txt format.So I have to do scraping.I want to know whether one can extract text data programmatically and automatically from applications other than browsers.I want to get the output file ~/Desktop/foo.txt.So for example, when many lines more than 100 in terminal are scrolling,is it possible to do scraping the terminal output without using [ctrl + c + v] neither [Edit & Copy]?For second example, when many slides are appearing in the slide show mode of Libre Office Impress,is it possible to do scraping all the text data?I want to know the method applicable to all other applications.Is there such a method other than screenshot & OCR?What package offers such a function?
