# ![Prybar](https://raw.githubusercontent.com/replit/prybar/master/logo.svg)

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

## Why

At [Repl.it](https://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!

## How it works

Prybar, written in [Go](https://golang.org/), maintains a common
command-line interface that calls into a select language backend. When
possible, the language backends are implemented using cgo and the
language's C-bindings. Otherwise, they make use of a small script
written in the host language which starts a Prybar-compatible REPL.

## Usage

Usage: ./prybar-LANG [FLAGS] [FILENAME]...
      -I	interactive (use readline repl)
      -c string
        	execute without printing result
      -e string
        	evaluate and print result
      -i	interactive (use language repl)
      -ps1 string
        	repl prompt (default "--> ")
      -ps2 string
        	repl continuation prompt (default "... ")
      -q	don't print language version

## Start to Develop with Nix

Look in `packages` in `flake.nix`. For each package present, you can do

```
nix build .#<package name>
```

to build it. The result will be a directory named `result`.

Example:

```
$ nix build .#prybar-python311
$ ls result/bin
prybar-python311
```

Alternately, you can use the nix shell. Enter

```
nix develop
```

to drop into a shell that has all dependencies installed an ready to go.

If you don't have nix yet, install that: https://nixos.org/

## Build and run

% make help
    usage:
      make all          Build all Prybar binaries
      make prybar-LANG  Build the Prybar binary for LANG
      make docker       Run a shell with Prybar inside Docker 
                        (don't do this in the nix shell, although this is
                                                not needed if you use nix)
      make image        Build a Docker image with Prybar for distribution
      make test         Run integration tests
      make test-image   Test Docker image for distribution
      make clean        Remove build artifacts
      make help         Show this message

### Distribution

Run `make image` to create a Docker image containing not only Prybar's
dependencies and source code but also its compiled binaries, which can
be embedded inside other Docker images by means of `COPY
--from=basicer/prybar`.

This image is automatically built and deployed to [Docker
Hub](https://hub.docker.com/) every time a commit is merged to
`master`.
