Write an extension for I❤️LA so that you can program with it in VSCode.

  • minimum goal: be able to write I❤️LA (displayed in a pretty way) and to compile it on the local PC

  • close C++ optimization support gap

    • reason for the gap: choice of library, which library could be used instead?
    • generate efficient solutions for certain Optimization problems like using the Pseudo Inverse

  • complete semantic highlighting, error checking

  • latex Rendering

    • could use features exposed by VSCode LaTeX extensions

  • Compile-to-clipboard-functionality, Compile-to-shared library as possible feature

  • run with user input or file, output result or file

  • custom preprocessor import statement for I❤️LA (so that you can directly import compiled I❤️LA Code into C++ in the build process)

compilation features (implementation)

  • run i<3LA function
    • variable rename (of return type and function name)
      • possibly implicit inferred auto return type
    • compile to temporary script which obtains user-defined inputs
    • syntactically substitute generated random data with user-provided input
    • rewrite matlab output
      • change last line to "output = mat2str(value)"
      • run with octave --no-window-system --exec-path "$(pwd)" --eval "${functionName}()" 2> /dev/null
        • function name should coincide with file name
      • or pipe the error into a temporary log so that it can be shown if an error occurred during execution
    • rewrite python output
      • remove input print statements from the main if-block (only Python)
      • run with python3 ${fileName}.py
    • execute temporary script and delete it afterwards (or cache using the hash of a "normalized" iheartla program?)
      • normalization: remove all whitespace and replace newline with ';' replace variable names with generated ones and whitespace between juxtaposed variables
    • allow file input to be an i<3LA constant expression (either inline or as file path) or a list of inputs as a file which produces a list of outputs
    • allow output to file, (new) editor, clipboard, cursor or message box
  • compile i<3LA function into a new text editor (together with includes or imports)
  • compiler diagnostics (VSCode diagnostics provider)
  • compile output function to clipboard (VSCode has a clipboard API)
  • compile comments (or special #includes) and add the generated source code into the function body below the comment/#include
  • compile file to C++ generated shared library into the current directory
