Oil Shell

Oil is a new Unix shell. Shell languages provide an (IEEE standardised) interactive command language and interactive scripting environment used to control computer operating systems. Shell scripts are deployed and used visibly and invisbly to command or glue together different applications and control the execution of tasks. Oil is the upgrade path from traditional shells like bash to a better and more structured language and runtime. It already runs thousands of lines of unmodified POSIX compliant shell scripts (as well as bash scripts which aren't compliant), but in a safer and more reliable way.

OSH can be smoothly upgraded to Oil, a new shell language influenced by Python, Ruby, JavaScript, JSON, and YAML. Oil also offers a basic interactive shell UI, and a "headless" API for building GUIs on top of shell. This project will finish the translation from statically typed Python to C++. This will let it match the speed of bash and existing shells, while offering reliable error handling, safe processing of user-supplied data, the elimination of quoting issues and better error messages and tools.
