Hello world/Newbie: Difference between revisions

=={{header|Jakt}}==

The Jakt compiler must be built from source; check [https://github.com/SerenityOS/jakt/blob/main/documentation/cmake-bootstrap.md the bootstrapping documentation] for the instructions.

As of writing, clang 14 seems to be the recommended version for compiling.

In summary, install cmake and run the following commands to build:

<syntaxhighlight lang="sh">

cmake -B build -GNinja

cmake --build build

</syntaxhighlight>

To compile hello world, save the following to hello.jakt:

<syntaxhighlight lang="jakt">

fn main() {

println("Hello world!")

}

</syntaxhighlight>

To compile it, run the following command in the directory containing hello.jakt.

<syntaxhighlight lang="sh">

jakt hello.jakt

</syntaxhighlight>

The built executable will be ./build/hello.

Specifying -cr will automatically run the program after building.

<syntaxhighlight lang="sh">

jakt -cr hello.jakt

</syntaxhighlight>

Output will go to the terminal.
