# NectarJS becomes Nerd
Compile JavaScript and NerdLang in native binaries.
# What is NerdLang
NerdLang is a substract of JS with some additions, focus on efficiency.
**Nerd** is a **JavaScript native compiler** aiming to make JavaScript universal, Nerd is able to compile native apps for Windows, Mac, Linux, iOS, Android, Raspberry, STM32 and more.
> **Nerd** is in active development, join us on [Discord](https://discord.gg/cpe2UuN) if you need more information.
- [Roadmap on Trello](https://trello.com/invite/b/6F4rvEj2/ATTI8842296bacc92724fa8b4114fe1dc80aA9FA431B/nerd)
## Main objectives
* Supporting EcmaScript 3 standard (then 5, 6 ...)
* Supporting NodeJS and NPM ecosystem
* Supporting a maximum of platforms (Windows, Mac, Linux, Android, Arduino, ...)
* Being secure
* Embeding debuging tools
* Compile everything that can be transpiled in JS: Ruby (Opal), Python (Transcript, Brython, JavaScrypthon), TypeScript ...
# Get started
## Installation
### Install GCC/CLang for your platform
- Windows
Install Mingw and Clang for Windows here: http://winlibs.com/ or Clang here: https://releases.llvm.org/
You can also install Linux for Windows and use a linux system on Windows
You need MinGW with POSIX threads
- Linux / FreeBSD
Install it with your distro (apt install gcc, yum install gcc, ...).
You can use GCC, CLANG, as well as any derivative of those compilers (arm-gcc ...)
- Apple iOS
Install xCode and you are ready.
You can check your installation with `npm start njs_test`
## Usage
Simplest way to use Nerd:
```
nerd file.js / file.ng
```
The output file name will be automatically chosen regarding the target. You can specify another output with `-o something.out`
You can select a preset
```
nerd file.js --preset [none|speed|size]
```
You can also run the compiled executable just after compilation using --run:
```
nerd file.js --run
```
You can enable the quiet mode with --quiet:
```
nerd file.js --quiet
```
Changing the stack size (useful on Windows):
```
nerd --stack 10000000 flood.js
```
For more informations about compilation output, use `--verbose`
For help, use `--help`
