# Simple RPN calculator

## About

Very simple RPN calculator. Works with STDIN and arguments. Also has a gtk version.

## Build Status

[![Build Status](https://travis-ci.org/hasufell/clac.png)](https://travis-ci.org/hasufell/clac)

## Install

clac is installed using cabal:

```cabal install```

It works well in a sandbox too:

```cabal sandbox init && cabal install```

## Run

If your cabal binaries are in $PATH after installing, invoke clac like any

other program:

```

clac-cli

```

It can also be ran via cabal (inside a sandbox or not):

```cabal run clac-cli```

To run the gtk version:

```cabal run clac-gtk```

## Usage

Straightforward RPN calculator.

```

$ clac-cli 1 2 - 3 +

$ echo 1 2 - 3 + | clac-cli

$ clac-cli

  1 1 +^D

```

It supports multiple equations.

```clac-cli 1 1 + , 2 2 +```

For available operators, check the operator list.

```clac-cli -o```

To print the entire equation as a tree, run in verbose mode.

```clac-cli -v```

## TODO

* Using something more appropriate than Double

* Support for implicit multiple equations (currently only supports explicit)

* Better pretty printing (intermediate calculations for instance)
