Oils for Unix

Bringing shell environments into the 21st century

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 invisibly 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 YSH, a new shell language influenced by Python, Ruby, JavaScript, JSON, and YAML. YSH also offers a basic interactive shell UI, and a "headless" API for building GUIs on top of shell. Through its set of specification languages, scripts can be translated to fast C++.

Goal of this project is to implement various new builtin YSH methods and functions (Str, Dict, IO, ...), implement JSON / J8 Data languages, create a Flag parsing lib and test framework, and significantly improve documentation throughout the entire project.
