LLVM, Clang and LLD are quite light on dependencies, requiring only standard

build tools to be built. Go is of course necessary to build TinyGo itself.

* Go (1.18+)

* GNU Make

* Go (1.13+)

# How to contribute
|
||||
|
||||
Thank you for your interest in improving TinyGo.
|
||||
|
||||
We would like your help to make this project better, so we appreciate any contributions. See if one of the following descriptions matches your situation:
|
||||
|
||||
### New to TinyGo
|
||||
|
||||
We'd love to get your feedback on getting started with TinyGo. Run into any difficulty, confusion, or anything else? You are not alone. We want to know about your experience, so we can help the next people. Please open a Github issue with your questions, or you can also get in touch directly with us on our Slack channel at [https://gophers.slack.com/messages/CDJD3SUP6](https://gophers.slack.com/messages/CDJD3SUP6).
|
||||
|
||||
### Something in TinyGo is not working as you expect
|
||||
|
||||
Please open a Github issue with your problem, and we will be happy to assist.
|
||||
|
||||
### Something in Go that you want/need does not appear to be in TinyGo
|
||||
|
||||
We probably have not implemented it yet. Please take a look at our [Roadmap](https://github.com/tinygo-org/tinygo/wiki/Roadmap). Your pull request adding the functionality to TinyGo would be greatly appreciated.
|
||||
|
||||
Please open a Github issue. We want to help, and also make sure that there is no duplications of efforts. Sometimes what you need is already being worked on by someone else.
|
||||
|
||||
A long tail of small (and large) language features haven't been implemented yet. In almost all cases, the compiler will show a `todo:` error from `compiler/compiler.go` when you try to use it. You can try implementing it, or open a bug report with a small code sample that fails to compile.
|
||||
|
||||
### Some specific hardware you want to use does not appear to be in TinyGo
|
||||
|
||||
As above, we probably have not implemented it yet. Your contribution adding the hardware support to TinyGo would be greatly appreciated.
|
||||
|
||||
Please start by opening a Github issue. We want to help you to help us to help you.
|
||||
|
||||
Lots of targets/boards are still unsupported. Adding an architecture often requires a few compiler changes, but if the architecture is supported you can try implementing support for a new chip or board in `src/runtime`. For details, see [this wiki entry on adding archs/chips/boards](https://github.com/tinygo-org/tinygo/wiki/Adding-a-new-board).
|
||||
|
||||
Microcontrollers have lots of peripherals (I2C, SPI, ADC, etc.) and many don't have an implementation yet in the `machine` package. Adding support for new peripherals is very useful.
|
||||
|
||||
## How to use our Github repository
|
||||
|
||||
The `release` branch of this repo will always have the latest released version of TinyGo. All of the active development work for the next release will take place in the `dev` branch. TinyGo will use semantic versioning and will create a tag/release for each release.
|
||||
|
||||
Here is how to contribute back some code or documentation:
|
||||
|
||||
- Fork repo
|
||||
- Create a feature branch off of the `dev` branch
|
||||
- Make some useful change
|
||||
- Make sure the tests still pass
|
||||
- Submit a pull request against the `dev` branch.
|
||||
- Be kind
|
||||
|
||||
## How to run tests
|
||||
|
||||
To run the tests:
|
||||
|
||||
```
|
||||
make test
|
||||
```

TinyGo is a Go compiler intended for use in small places such as microcontrollers, WebAssembly (wasm/wasi), and command-line tools.
|
||||
TinyGo is a Go compiler intended for use in small places such as microcontrollers, WebAssembly (Wasm), and command-line tools.
|
||||
|
||||
It reuses libraries used by the [Go language tools](https://golang.org/pkg/go/) alongside [LLVM](http://llvm.org) to provide an alternative way to compile programs written in the Go programming language.
|
||||
|
||||
## Embedded
|
||||
|
||||
Here is an example program that blinks the built-in LED when run directly on any supported board with onboard LED:
|
||||
|
||||
```go
|
||||
@@ -37,62 +35,86 @@ The above program can be compiled and run without modification on an Arduino Uno
|
||||
tinygo flash -target arduino examples/blinky1
|
||||
```
|
||||
|
||||
## WebAssembly
|
||||
|
||||
TinyGo is very useful for compiling programs both for use in browsers (WASM) as well as for use on servers and other edge devices (WASI).
|
||||
|
||||
TinyGo programs can run in Fastly Compute@Edge (https://developer.fastly.com/learning/compute/go/), Fermyon Spin (https://developer.fermyon.com/spin/go-components), wazero (https://wazero.io/languages/tinygo/) and many other WebAssembly runtimes.
|
||||
|
||||
Here is a small TinyGo program for use by a WASI host application:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
//go:wasm-module yourmodulename
|
||||
//export add
|
||||
func add(x, y uint32) uint32 {
|
||||
return x + y
|
||||
}
|
||||
|
||||
// main is required for the `wasi` target, even if it isn't used.
|
||||
func main() {}
|
||||
```
|
||||
|
||||
This compiles the above TinyGo program for use on any WASI runtime:
|
||||
|
||||
```shell
|
||||
tinygo build -o main.wasm -target=wasi main.go
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
See the [getting started instructions](https://tinygo.org/getting-started/) for information on how to install TinyGo, as well as how to run the TinyGo compiler using our Docker container.

### WebAssembly
|
||||
|
||||
TinyGo programs can be compiled for both WASM and WASI targets.
|
||||
|
||||
For more information, see https://tinygo.org/docs/guides/webassembly/
|
||||
|
||||
### Operating Systems
|
||||
|
||||
You can also compile programs for Linux, macOS, and Windows targets.
|
||||
|
||||
For more information:

||||
- Linux https://tinygo.org/docs/guides/linux/
|

|
||||
- macOS https://tinygo.org/docs/guides/macos/
|
||||
|
||||
- Windows https://tinygo.org/docs/guides/windows/
|
||||
For more information, see [this list of boards](https://tinygo.org/microcontrollers/). Pull requests for additional support are welcome!

Non-goals:
|
||||
|
||||
* Using more than one core.
|
||||
* Be efficient while using zillions of goroutines. However, good goroutine support is certainly a goal.
|
||||
* Be as fast as `gc`. However, LLVM will probably be better at optimizing certain things so TinyGo might actually turn out to be faster for number crunching.
|

* Be able to compile every Go program out there.
