Description:

rpncalc 0.2.3

pol

Command line calculator using reverse polish notation
Decimal, hexadecimal, binary and octal number are supported
Usage
As a command line tool: pol
~$ pol
Reverse polish notation calculator
>5 10 * dec
50
>0xA 0x6 + hex
0x10
>q //quit the program
~$

Instructions are below
pol can also be use as a module
import rpn_calc
cal = rpn_calculator.Calculator()
cal.evaluate("1 2 + dec")
# print 3

Install
pol can be install from pip
pip install rpn-calc

If you want to install from a source distribution, extract the tarball and run the following command
python setup.py install

Documentation
This README is the Documentation
Repo
The code is on github
Config file
You can write your own command
By default commands from file ~/pol.yml (if exists) are add to the calculator
You can add other files with the flag -f/--file
Config files are written in YAML
Currently supported parameters

shortcut: shortcut to commands (see example below)
rounding: parameter used to round number (default: 0)

Example of a valid config file
shortcut:
- double = 2 * # double the last value of the stack
- 10* = 10 switch ** # same as 10 {x} **
rounding: 3

Command must be on the format {name_of_command = command}
Options
usage: pol [-h] [-v] [-l] [--ignore-local-config] [-f FILE [FILE ...]]

A RPN calculator written in python
Support decimal, hexadecimal, binary and octal

optional arguments:
-h, --help show this help message and exit
-v, --version show the version number and exit
-l, --list list all commands available and exit
--ignore-local-config
don't add commands from ~/.pol
-f FILE [FILE ...], --file FILE [FILE ...]
file with customs commands
