Project Overview

Project Name: Julia backend for Cantor

A Brief Description: The goal of the project is to implement Julia support for Cantor worksheet application with folowing features: command execution, variable management, syntax-highlighting, inline plotting and binding to existing wizards.

Status:

• Completed :
  • Command execution
    • Error handling
    • Interrupt handling
    • Multiline input
    • Syntax errors
    • Unit-tests
  • Syntax highlighting
    • Simple keyword highlighting
    • Highlighting based on extracted symbols and their types
    • Correct highlighting of string literals and comments (ported also to Python backend)
  • Variable management
    • Showing available variables
    • Saving, loading, clearing, adding new variable
    • Caching of modules variables for faster update
  • Inline plots
  • Tab-completion
    • Accounts current context, not simply showing all known symbols
  • Bindings for linear algebra and plotting wizards

• In progress:
  • Unit-tests for inline plots
  • Unit-tests for tab-completion

This is what I learned during GSoC:

• Working with Phabricator
• Get deeper knowledge of Qt5
• Get familiar with KDEFrameworks
• Understanding good Julia internals, especially part connected with embedding
• More advanced Git stuff, like rebases
