# The Kitten Programming Language
[][gitter] [](https://travis-ci.org/evincarofautumn/kitten)
**Kitten** is a statically typed, [stack-based functional programming language][concatenative] designed for simplicity, speed, and safety. This is an in-progress implementation of that language, including:
* An interactive console for testing code
* An interpreter
* A native-code compiler producing static executables (incomplete)
## Contributing
I need help to make Kitten a reality! If you’re interested in helping in any way, you’re more than welcome, even if you’re not experienced with Haskell or compiler development. You can look at the project for the [initial release] to see what I’m working on, and check out the [contribution guidelines][contributing] for suggestions on how you can help.
## Resources
* Browse some [examples][examples] to get a feel for the language
* Join the [chat room][gitter] to ask questions
* Skim a quick [intro][intro] on the [official site][site]
* Read the most recent updates to the [ebook][ebook]
* Read my article introducing some interesting things about concatenative programming, [Why Concatenative Programming Matters][wcpm]
* Watch my lecture describing the theory, history, and implementation techniques of the paradigm, [Concatenative Programming: From Ivory to Metal][cpim]
## Building and Installing
If you’re building the compiler just to try it out or work on it, you can follow the preferred build method of using [Stack]:
```
git clone https://github.com/evincarofautumn/kitten.git
cd kitten
stack setup # only necessary on first build
stack build
stack exec kitten
stack exec kitten --
```
However, if you want to *install* Kitten in a standard location outside the build directory, due to a deficiency in Stack’s support for Cabal’s `data-files` feature, it is **not** recommended to use `stack install` to install a copy of the executable, because this will not install the *common vocabulary* `common.ktn` containing Kitten’s standard library.
There are two workarounds. One is to forgo Stack, and build and install Kitten using Cabal directly:
```
cabal sandbox init
cabal install --only-dependencies
cabal install --prefix="$HOME/.local"
```
This will correctly install the common vocab so that Kitten can find it. The preferred install location for Kitten is `~/.local` on Unix-like systems (so the executable resides at `~/.local/bin/kitten`) or `%APPDATA%\local` on Windows (resp. `%APPDATA%\local\bin\kitten.exe`).
The other option is to manually copy `common.ktn` to the install directory:
```
stack install
cp common.ktn ~/.local/bin/
```
It’s also recommended to add the install directory (`~/.local/bin` or `%APPDATA\local\bin`) to your `PATH` so that you can invoke `kitten` directly without a path prefix.
These are the only files installed by Kitten, so to uninstall it, you only need to delete the compiler and common vocab from the install directory.
