Callang

Callang calls other languages to run scripts while in python.

Currently implemented languages

• Octave
  • MatLab¹ clone with some reverse compatability
  • Used for matric processing and general analytics
• R
  • General statistical analysis language

Executables used in python's subpocess call to run CLI, GUI, or Script

Use	Octave	R
Script execution	octave.exe	R.exe
Command line interface (CLI)	octave-cli.exe	R.exe
Graphical user interface (GUI)	octave-gui.exe	Rstudio.exe

Issues noticed

• Octave (.m) files will only run on relative paths if they are scripts, not functions

• Different versions of R installed are located in different folders. This can be solved by reading the directory with os rather than hardcoded.

  • Solved, somewhat ugly but reads directory, creates a string of the folder name and version, and then appends as the directory absolute path. Still only works on windows and in default installation location.

• GUI call leaves command line inoperable until the GUI is closed
