Prybar is a universal interpreter front-end. Same interface, same REPL, different languages.

At Repl.it we're in the business of running REPLs. As it happens to be every language implements them differently. We wanted them to all behave the same: run code and drop into a REPL!

Prybar, written in Golang, maintains a common command-line interface that calls into a select language backend. The language backends are implemented using cgo and the language's C-bindings.

Usage of ./prybar-language:
  -I	like -i, but never use language REPL
  -c string
    	code to run
  -e string
    	expression to print
  -i	interactive
  -ps1 string
    	PS1 (default "--> ")
  -ps2 string
    	PS2 (default "... ")
  -q	quiet

Prybar uses a Unix make file to build each Prybar binary with pkg-config to find language dependencies on your system.

See Dockerfile for hints what packages to install on linux.

brew install go r ruby python python@2 lua spidermonkey

The script ./extract.sh can be used to compile and produce a tarball containing all the Prybar binaries. Each binary will be named prybar-<language>. You can build all languages by running make in the repo's root or run make prybar-<language> to build a specific language.
