You are encouraged to solve this task according to the task description, using any language you may know.
Find the total number of programming examples for each task and the total for all tasks.
Essentially, count the number of occurrences of =={{header| on each task page.
Output:
100 doors: 20 examples. 99 Bottles of Beer: 29 examples. Abstract type: 10 examples. Total: X examples.
For a full output, updated periodically, see Rosetta Code/Count examples/Full list.
You'll need to use the Media Wiki API, which you can find out about locally, here, or in Media Wiki's API documentation at, API:Query

jq
jq does not duplicate the functionality of `curl` but works seamlessly with it, as illustrated by the following bash script. Note in particular the use of jq's `@uri` filter in the bash function `titles`.
<lang bash>#!/bin/bash
- Produce lines of the form: URI TITLE
function titles {
local uri="http://www.rosettacode.org/mw/api.php?action=query&list=categorymembers" uri+="&cmtitle=Category:Programming_Tasks&cmlimit=5000&format=json" curl -Ss "$uri" | jq -r '.query.categorymembers[] | .title | "\(@uri) \(.)"'
}
- Syntax: count URI
function count {
local uri="$1" curl -Ss "http://rosettacode.org/mw/index.php?title=${uri}&action=raw" | jq -R -n 'reduce (inputs|select(test("=={{header\\|"))) as $x(0; .+1)'
}
local n=0 i while read uri title do
i=$(count "$uri") echo "$title: $i examples." n=$((n + i))
done < <(titles) echo Total: $n examples.</lang>
- Output:
100 doors: 252 examples. 15 Puzzle Game: 36 examples. 2048: 24 examples. ... Order two numerical lists: 65 examples. Ordered Partitions: 28 examples. Ordered words: 85 examples. Palindrome detection: 136 examples. Total: 32416 examples.

Retrieves counts for both Tasks and Draft Tasks. Save / Display results as a sortable wikitable rather than a static list. Click on a column header to sort on that column. To do a secondary sort, hold down the shift key and click on a second column header. Tasks have a gray (default) background, Draft Tasks have a yellow background.

Ruby
First, a RosettaCode module, saved as rosettacode.rb: <lang ruby>require 'open-uri' require 'rexml/document'
module RosettaCode
URL_ROOT = "http://rosettacode.org/mw"
def self.get_url(page, query) begin # Ruby 1.9.2 pstr = URI.encode_www_form_component(page) qstr = URI.encode_www_form(query) rescue NoMethodError require 'cgi' pstr = CGI.escape(page) qstr = query.map {|k,v| "%s=%s" % [CGI.escape(k.to_s), CGI.escape(v.to_s)]}.join("&") end url = "#{URL_ROOT}/#{pstr}?#{qstr}" p url if $DEBUG url end
def self.get_api_url(query) get_url "api.php", query end
def self.category_members(category) query = { "action" => "query", "list" => "categorymembers", "cmtitle" => "Category:#{category}", "format" => "xml", "cmlimit" => 500, } while true url = get_api_url query doc = REXML::Document.new open(url)
REXML::XPath.each(doc, "//cm") do |task| yield task.attribute("title").value end
continue = REXML::XPath.first(doc, "//query-continue") break if continue.nil? cm = REXML::XPath.first(continue, "categorymembers") query["cmcontinue"] = cm.attribute("cmcontinue").value end end
end</lang>
Then, we implement the task with: <lang ruby>require 'rosettacode'
total_examples = 0
RosettaCode.category_members("Programming_Tasks") do |task|
url = RosettaCode.get_url("index.php", {"action" => "raw", "title" => task}) examples = open(url).read.scan("=={{header").length puts "#{task}: #{examples}" total_examples += examples

puts puts "Total: #{total_examples}"</lang>
