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 Go, 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: ./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

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/
% 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
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 every time a commit is merged to
master
.
