6.1.16 news.ex
Search news pages
All this demo does is read several Web pages in parallel and report on the number of occurrences of a word or phrase. Each page is handled by a separate Euphoria task running in parallel with several other tasks.
6.1.16.1 Usage
eui news.ex string
or:
eui news.ex "a multi-word phrase"
Search is case insensitive.
This demo uses Euphoria's multitasking feature. It can run without change on all platforms supported by OpenEuphoria.
A Euphoria task is assigned to each instance URL query, searching the Web page text as it arrives. In this way, when a task is blocked due to a delayed response from a particular server, the program can easily switch to another task that is not blocked. The program quits after a period of 10-15 seconds with no progress made on any page.
