Changelog

master - unreleased

0.0.6 - 2022-02-16

  • (internal) restructure custom WikipediaQL selectors internally into having "attrs" and "functions" (CSS pseudo-selectors), paving the way for more consistency;
  • add sentence:first and section:first functions;
  • improve default YAML output formatting;
  • improve table-data quasi-selector behavior to handle mid-table full-row th (it gets attached as a prefix to subsequent rows).

0.0.5 - 2022-01-26

  • Add executable script wikipedia_ql to run from command-line!
  • Streamline and simplify the language.
    • There is now only one way of nesting: selector1 >> selector2, {} is left only for grouping purposes;
    • Follow the CSS selectors intuition: text["pattern"] is now text:matches("pattern"), sentence["pattern"] is sentence:contains("pattern"), and text-group[1] is text-group[group=1]
  • A number of internal bugfixes and simplifications
  • The further development is covered in near-the-realtime on my Substack

0.0.4 - 2021-11-30

  • The largest highlight is table-data quasi-selector/filter, allowing to regularize tables and fetch data by columns/rows. See Tables.md for details;
  • Improve results joining to be (a bit) more reasonable and allowing to fetch multiple hashes;
  • Add support for fetching style attributes (naive!) with selectors like @style-background;
  • Support $= and ^= attribute operators.

0.0.3 - 2021-10-08

The largest highlight of the release is links following: now you can go through pages graph in a single query!

from wikipedia_ql import media_wiki

wikipedia = media_wiki.Wikipedia()

pprint(wikipedia.query(r'''
    from "The Wachowskis" {
        section[heading="Films"] {
            table >> tr >> td:nth-child(2) {
                a -> {
                    @title as "film";
                    section[heading="Critical response"]
                        >> sentence["Rotten Tomatoes"]
                        >> text["\d+%"] as "rotten-tomatoes";
                }
            }
        }
    }
'''))

This prints:

[{'film': 'Assassins (1995 film)'},
 {'film': 'Bound (1996 film)', 'rotten-tomatoes': '89%'},
 {'film': 'The Matrix', 'rotten-tomatoes': '88%'},
 {'film': 'The Matrix Revisited'},
 {'film': 'The Animatrix'},
 {'film': 'V for Vendetta (film)', 'rotten-tomatoes': '73%'},
 {'film': 'The Invasion (film)'},
 {'film': 'Speed Racer (film)', 'rotten-tomatoes': '41%'},
 {'film': 'Ninja Assassin', 'rotten-tomatoes': '26%'},
 {'film': 'Cloud Atlas (film)', 'rotten-tomatoes': '66%'},
 {'film': 'Jupiter Ascending', 'rotten-tomatoes': '27%'},
 {'film': 'The Matrix Resurrections'}]

(Yeah, not all movies are there... Table parsing is still to be enhanced)

Other changes in query language:

  • text without pattern (the text of entire element);
  • text-group["group name"] named groups from text patterns;
  • sentence without pattern (all sentences in the scope)
  • standalone @attribute (attribute of the current selected element);
  • for @href and img@src attributes URLs are now expanded to fully-qualified ones.

Changes to HTTP query engine:

  • Using Parsoid API instead of default Wikipedia api.php to fetch HTML content — #2;
  • Providing sensible User-Agent string (and allow library user to rewrite it) — #1.

0.0.2 - 2021-07-05
