Installation

Melang relies on the core C library Melon, so it needs to be installed first. We can use the following commands to quickly install Melon:

git clone https://github.com/Water-Melon/Melon.git
cd Melon
./configure
make
sudo make install

If you are a Windows user, please refer to Melon installation for more details.

Then, we can execute the following commands to install Melang:

git clone https://github.com/Water-Melon/Melang.git
cd Melang
./configure
make all
sudo make install

The configure command has the following parameters:

• --help Output the help information.
• --prefix The installation path for Melang.
• --melon-prefix The installation path for the core library Melon.
• --lib-prefix The installation path for the dynamic libraries used by the Melang.
• --enable-mysql Enable the MySQL feature, which means compiling the MySQL dynamic library used by Melang.
• --mysql_header_path The header files path for libmysqlclient (If they cannot be found in /usr/include or any other default header loading path).
• --mysql_lib_path The library path for libmysqlclient (If they cannot be found in /usr/lib or any other default library loading path.).
• --enable-wasm Compile into a wasm format file.
• --debug Enable debug mode, which is used for developing and debugging Melang.

Now you can use Melang for development.

Example

Here is a Melang script file.

//example.m

sys = Import('sys');
sys.print("Hello World!");

Then execute

melang example.m

The output is

Hello World!
