Jazz is a language that makes programming embedded, web, apps etc easier using a simple scripting language with the tools you need built-in by the Rust and Lua communities.  (It's currently being renamed from Torchbear.)



## Blessed Rust Modules



As you wish to solve more use cases with your programs, you can access [Torchbear's functions](#built-in-modules), which are described below and viewable in the [bindings' documentation](https://foundpatterns.github.io/torchbear-docs/index.html) (generated using our [code map](http://github.com/foundpatterns/lua-module-map) app).

## Get Started



Jazz comes as a single executable (eg. as a binary `.exe` file) which makes it easy to install and easy to run apps.  It also comes with a package manager, called [Machu Picchu](https://github.com/foundpatterns/machu-picchu), which helps you to download more apps.



### Install



To install Jazz on Android or Windows, run this command using your terminal ([what's a terminal?](#what-is-a-terminal)):



```sh

 curl https://git.io/fpcV6 -sSfL | bash

```



MacOS and Linux users will need admin permissions to run:



```sh

 curl https://git.io/fpcV6 -sSfL | sudo bash

```



[The installer](https://github.com/foundpatterns/torchbear/blob/master/install.sh) automatically gets the latest version (which is also available on [Torchbear's GitHub releases page](https://github.com/foundpatterns/torchbear/releases)) and puts it in a convenient file location for you.  To do this, it downloads the latest zip file for your operating system and hardware architecture, then it unzips the executable to a place where it will run as a command.  You can do that manually or differently, as you like.



#### What is a terminal? (command prompt)



If you haven't heard of a terminal before, here's a [1 min intro to what is a terminal window](https://www.youtube.com/watch?v=zw7Nd67_aFw).  This works on Android, Windows, MacOS, and Linux devices very similarly, but you might need one other tool first:



* Android: install [Termux](https://termux.com/).



* Windows: install [Cmder](http://cmder.net/) Full (within your user directory, eg not in Program Files).



* MacOS:  mostly ready out-of-the-box.



* Linux: mostly ready out-of-the box.



* iOS: work in progress, see [Torchbear iOS build (iPhone and iPad)](https://github.com/foundpatterns/torchbear/issues/120)



* [Redox](https://redox-os.org/): work in progress, see [Torchbear Redox release](https://github.com/foundpatterns/torchbear/issues/18)



### Update



To update, run `torchup`.



### Uninstall



To uninstall, run `torchup --uninstall`.



## Development



#### Hello World App



1. put this in `init.lua`:



```lua

#!/usr/bin/env speakeasy



print("hello from Torchbear")

```



2. make it executable with `chmod +x init.lua`



3. then run it with `./init.lua`



**Note:** [Machu Picchu](https://github.com/foundpatterns/machu-picchu) also works as a dependency manager, making deploying and developing component-oriented software easy.  Check how other projects use it until more documentation is available.  Also can start finding some useful library scripts for your programs in our [Lunar Transit](https://github.com/lunar-transit) account.



#### Rust Development



You can compile from source by [installing Cargo](https://www.rust-lang.org/tools/install) (Rust's package manager) and installing `torchbear` using Cargo:



`cargo install torchbear`



Compiling from this repository also works similarly:



```

git clone https://github.com/foundpatterns/torchbear

cd torchbear

cargo build --release

```



Note: You will also need a C compiler, eg on Debian-based Linux distros `sudo apt install build-essential`.  Compilation will probably take several minutes depending on your machine and your network speed. The binary will end up in `./target/release/torchbear`.



## App Stores



* [Found Patterns Studio App Store](https://github.com/foundpatterns/app-store) (installed by default)

* yours?



## Contributors wanted



Torchbear extends Rust's growing library ecosystem. Developers and users alike are welcomed to participate in [Torchbear's issue queue](https://github.com/foundpatterns/torchbear/issues) for small changes and high impact contributions.  Everyone is invited.



Even moderately experienced Rust developers can work on [adding bindings](https://github.com/foundpatterns/torchbear/labels/feature%2Fbindings) or adding other functions.  There are many examples to learn from in the bindings directory.  Through this process, you'll learn a Rust library's API inside and out, and you'll put another tool into the hands of a thriving userbase.



Experienced Rust developers' reviews would be greatly appreciated, eg those familiar with low-level library idioms and especially those well-versed in [Actix](https://github.com/actix/actix).  Much of the power functionality built-in to Torchbear comes from libraries like Actix, Actix-Web, [Actix-Lua](https://github.com/poga/actix-lua), [rlua](https://github.com/kyren/rlua), and many more well-picked ones which need thorough review and careful analysis to make a good programming environment.



Users who who want to add a 'review' or 'story' about your use cases, simply add this "issue label" (type/review) or (type/story).  Everyone is welcomed to do so, and this will help users and developers understand Torchbear from eachother's points of view.  Developers who want to post other feedback and analysis will receive a hearty thank you.



## Community



Eveyone interested in learning and solving problems with programming and open-source tools in general is welcomed to come to [Found Patterns Studio's Discord Server](https://discord.gg/f6XSuWs) to meet fellow engineers and to work together on team-driven projects, like Torchbear.  If you haven't heard of [Discord](https://discordapp.com/) before, you could start with these videos, [Discord For Dummies: Basic Use and Set up Instructions for Discord App](https://www.youtube.com/watch?v=7BFytSpuAWs) and [How To Setup And Use Discord - Basic Overview Of Features and Tools](https://www.youtube.com/watch?v=E7xznRGg9WM).  We use it to help eachother use and build Torchbear and many other projects.  It's a safe and friendly place to get things done.
