Building the first program
Creating a package
To create your first package, run a pen create
command with your package's name in your terminal.
pen create foo
Then, you should see a directory named foo
in your current directory. When you go into the directory, you should see a main.pen
source file and a pen.json
file for package configuration.
Building a package
To build the package, run a pen build
command in the foo
directory.
pen build
Then, you will see an executable file named app
in the directory. Run it to see your first "Hello, world!"
./app # -> Hello, world!
Now, you can start editing source files and build your own application in Pen!
