Read the installation steps to get daScript for your system, then read the tutorial.

We are going to need git, cmake, vscode and a C++ compiler for your platform.

git clone https://github.com/GaijinEntertainment/daScript
cd daScript
cmake -B build -G "Unix Makefiles"
cd build && make daScript -j$(nproc)

You may also want to create a symlink in the /bin directory for easy access to the compiler.

sudo ln -s /home/andrew/daScript/bin/daScript /bin/das

Currently, the best supported editor is VSCode.

To set up the language server follow these instructions: daScript-plugin

Hint: if the autocompletion doesn't seem to work, try increasing dascript.server.connectTimeout plugin parameter up to 10 (or 20 in case of Debug build).

Now let's test what we've got:

1. Start small, an obligatory Hello world

# File: hello_world.das
# Run: das hello_world.das

[export]
def main
    print("Hello world\n")

In case you are wondering [export] annotation here ensures that function can be called externally given context.
