RosettaCode helper for Arturo
This package provides a comprehensive RosettaCode API wrapper for Arturo, enabling easy interaction with the RosettaCode wiki. It handles authentication, task retrieval, solution parsing, as well as structured access to task content/categories/examples/etc.
Simply import it and start exploring RosettaCode tasks:
import 'rosetta!
; Connect to RosettaCode
rc: to :Rosetta []!
; Get all implemented tasks for Arturo
tasks: rc\implemented "Arturo"
print ["Arturo has" size tasks "implementations"]
; Get information about a specific task
task: last tasks
print task\description
; Get the Arturo solution
if solution: <= task\solution "Arturo" [
loop solution\code 'code ->
print code
]
; Find tasks without Arturo implementation
unimpl: rc\unimplemented "Arturo"
print ["Missing implementations:" size unimpl]
; Get draft tasks
drafts: rc\drafts
print ["Draft tasks:" size drafts]The main RosettaCode API client
to :Rosetta []
\wiki- underlying MediaWiki API client\loggedIn- authentication status
Authenticate with RosettaCode.

Retrieve task content.
task title :string
- :rcTask - task object with parsed content
- :null - task not found or request failure
Get all tasks with implementations for given language.
implemented lang :string
- :block - array of :rcTask objects
Find all tasks without implementation for given language.
unimplemented lang :string
- :block - array of :rcTask objects
Get draft programming tasks.
drafts
- :block - array of :rcTask objects
Represents a RosettaCode task with its content, solutions, and metadata
to :rcTask [wiki :MW, title :string]
\wiki- MediaWiki API client reference\title- task title
Get task content, loading from wiki if needed.
content
- :string - task wikitext content
- :null - request failure
Check if task is a draft.
draft?
- :logical -
trueif task is a draft - :null - content not available
Get task description.
description
- :string - task description (text before first solution)
- :null - content not available
Get task categories.
categories
- :block - array of category names
- :null - content not available
Get all language solutions.
solutions
- :block - array of :rcSolution objects
- :null - content not available
Get solution for specific language.
solution lang :string
- :rcSolution - solution object for the specified language
- :null - language not found or content not available
Represents a language solution with extracted code and output
to :rcSolution [language :string, content :string]
\language- programming language name\code- array of extracted code blocks (from<syntaxhighlight>tags)\output- extracted output text (from{{out}}section)
Tip
All task data is lazily loaded and cached! The first call to \content, \solutions, etc. fetches and parses the content, then subsequent calls use the cached data. 😉
