Hana

Hana is an elegant, clean and minimalistic interpreted programming language inspired from lua, python and javascript <3

⚠️ WIP ...

For now Doxygen docs - 🌸 Hana Documentation

Deps

• Cmake >= 3.12
• Flex
• Bison
• LLVM (version 10.0.1)

Building the interpreter

git clone https://github.com/syylvette/Hana.git
cd Hana
mkdir Build && cd Build
cmake .. && make

## Generates a binary 'hana' in Build/Hana directory
./hana -h  ## Lists the usage

Builiding the binary might take few minutes depending on your Pc.
You can also get the binary from Releases, but it will probably only work on Arch or Arch other based distros, as the binary was built on Arch linux with x86 architecture.

Usage

Create a hana file

touch hello.hana && vim hello.hana

writeln("Hello World!")

Run

Using the hana interpreter

hana hello.hana

Output

Hello World!
