<p> No VM. No Bytecode. No packaging. No Garbage Collector. Fully compiled to native binaries. </p>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 if you need more information.
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
