Hydrogen is a small, lightweight programming language with C-style syntax. It's intepreted, dynamically typed, and sports a blazingly fast tracing JIT compiler, along with an easy to use C API, allowing you to quickly embed Hydrogen in your own programs.
Hydrogen is built using the CMake build system:
$ git clone https://github.com/GravityScore/Hydrogen
$ cd Hydrogen
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make installThis clones the GitHub repository, builds Hydrogen, and installs it on your system (in /usr/local).
You can run Hydrogen code using the command line interface:
$ hydrogen test.hyYou can start a REPL session like so:
$ hydrogenThe command line interface has a number of options:
| Option | Description |
|---|---|
-h |
Shows this help information. |
-v |
Shows the version number of the current Hydrogen installation. |
-b |
Prints the program's compiled bytecode. |
-s |
Doesn't execute a file, but rather treats the command line arguments as Hydrogen source code. |
-joff |
Turns off JIT compilation during runtime (slows down program execution). |
-jinfo |
Shows information about hot loops that are JIT-compiled during execution. |
