Swift Script Include

Because running Swift in command-line doesn't support including other files, I made a quick Python script that takes in an input file and replaces all instances of include "somefile.swift" with the contents of that file. This happens recursively so that included files can also include other files.

swiftinclude.py

The Python script needs an input file and an output file. By default, the input file is main.swift, and the output file is app.swift. You can also specify your own input and output files:

./swiftinclude.py -i input.swift -o output.swift

makefile

The provided makefile assumes that you have a main.swift file and creates an app.swift file. Running make produces the app.swift file, and running make run produces the app.swift file and runs it.

Example

After downloading the repo, simply run make run.

The included example will print Hello, World! to the console. The contents of the simple example is provided below.

main.swift

include "lib/test.swift"
helloWorld()

lib/test.swift

func helloWorld() {
    print("Hello, World!")
}

Notes

• When using include "filename.swift", double quotes are required.
• All paths are relative to the location of the Python script.
• If a file is included in multiple places, only the first instance of the include statement will be replaced with the file contents.
