Made as a dead-simple wrapper around Python that preimports

stuff from its **_math_ and _statistics_ modules** (including _numpy_, if available)

before dropping into the familiar REPL.

This replaces the functionality of several modern command-driven scientific calculators,

as available e.g. in Debian,

at less than half the source code lines spent! YMMV

Installation

------------

Download the script and put it somewhere on `$PATH`:

```sh

curl -vL 'https://bit.ly/pycalc-ng' | sudo tee /usr/local/bin/pycalc

sudo chmod +x /usr/local/bin/pycalc  # Mark it executable

```

Make sure Python 3 is available:

```sh

sudo apt install python3

```

A terminal emulator (`xterm` from _x11-utils_ (recommended), `gnome-terminal` or `konsole`)

serves as a simple GUI:

```sh

sudo apt install x11-utils

```

If you use a tiling window manager,

like _i3_, _awesome_, _xmonad_ or _dwm_,

additional utilities `xprop` and `xdotool` are required

to make the app window dialog-like (floating):

```sh

sudo apt install x11-utils xdotool

```

If you prefer a more full-featured Python REPL, such as _ptpython_ or _ipython3_

with syntax highlighting and Tab-based autocompletion,

those are automatically used if found!

```sh

sudo apt install ptpython  # or ipython3

```

Usage

-----

Simple invocation should spawn a new app window:

```sh

$ pycalc

```

... in which you can type your fancy equations:

```python-repl

>>> 1+1

2

```

Supports variable assignment just like Python does. Etc. 😋
