# pysh

Python-enhanced bash scripts.

[![Build Status](https://travis-ci.org/sharkdp/pysh.svg?branch=master)](https://travis-ci.org/sharkdp/pysh)

`pysh` allows you to write bash scripts that include short snippets of Python

code with a local environment that is shared between bash and Python.

## Example

Lines that start with `#> ` are evaluated as Python:

```bash

##### From bash to python #####

bashVariable="Hello world"

#> print("{} from python!".format(bashVariable))

##### From python to bash #####

#> pythonVariable = " ".join(["Hello", "world"])

echo "$pythonVariable from bash!"

######## Back and forth #######

for file in *.csv; do

    echo

    echo "before: $file"

    #> base, ext = os.path.splitext(file)

    #> file = base.upper() + ext

    echo "after:  $file"

done

```

Run it:

```

> ls

dummy.csv  important.csv  example.sh

> pysh example.sh

Hello world from python!

Hello world from bash!

before: dummy.csv

after:  DUMMY.csv

before: important.csv

after:  IMPORTANT.csv

```

## Caveats

This is only supported for Python 3.4 and above due to [`redirect_stdout`](https://docs.python.org/3/library/contextlib.html#contextlib.redirect_stdout).

## Disclaimer / warning

This is a prototype implementation with lots of evil hacks.
