Install

$ pip install pybooks

Usage

Simple usage

from pybooks.pbook import Pbooks 

pbook = Pbooks( author='jerome',
                title='elements of statistic',
                weights=(9, 1)) 
         

pbook.main()

The weights argument is used to calculate the accuracy of all the items found and the final chosen url. For example, a weights of (9, 1) will place more important on the author accuracy than title's hence it is more likely that the result will have author's name more similar to the input. Default weights are (1, 1)

Optional arguments are show_result: Print the result at the end or not, threshold: Only print result with accuracy higher than threshold and log: Show process while running or not, etc. More arguments can be found in the documentation of the code.

You can modify or add additional sources by editing the file pybooks/sources.json and follow the existing format within the file.

Sources.json format, rules

Example: Library Genesis with elements of statistics as search term

The only components we need in the URL are: request: ?req=..., delimiter: + (elements+of+statistics) and pagination: page=... and term_concatenation: & (req=...&page=...)

INSIDE SOURCES.JSON

URL: main url without search terms
URL_RULES: dictionary contains keys and values as search rules.
HTML_RULES: Contains nested dictionary represent necessary components to conduct searches such as tags, attributes for titles, authors, rows and page body
.POSITION: The position of the that element in the row if there are other similar elements with similar tag and attributes, leave as null if it is unique
.TAG: The tag of the desired element
.ATTRIBUTE: Attributes of the tag, for exanple: {"class": "id", "...": "..", ...}. Leave the value of a key as true if an attribute has no value
