SwiftFormat

Python script for auto formatting Swift code, similar to Clang format.

Current status: Gonna rewrite this to Swift.

Usage

auto format a file

Usage: 
--file [FILE] The file to format
--output [FILE] The file to write the formatted output to

python format.py --file inputfilename.swift --output outputfilename.swift

Demo

Contributing

All contributions are more than welcome, suggestions on how to move forward is appreciated.

Test format

Put source code to be formatted above @@@, and under put the correct way it should be formatted after running the format script.

class test() {{var str = "teststr" }}
@@@
class test() {
    {
        var str = "teststr"
    }
}

For each rule thats added, add a test file that shows how it should format correctly. The test checks that all files are formatted correctly as shown under the @@@ in their file.

Run tests

python tests.py
TEST OK for python/SwiftFormatter/testCases/indentation/indentTest.test
TEST OK for python/SwiftFormatter/testCases/indentation/lotsOfCurlyBraces.test
TEST OK for python/SwiftFormatter/testCases/indentation/mulitplemethodsinclass.test
TEST OK for python/SwiftFormatter/testCases/indentation/prefixedSpaces.test
TEST OK for python/SwiftFormatter/testCases/indentation/twoCurly.test

TODO

Add alot more formatting rules
be able to turn rules on/off

macholib can be used to analyze and edit Mach-O headers, the executable format used by Mac OS X. It's typically used as a dependency analysis tool, and also to rewrite dylib references in Mach-O headers to be @executable_path relative. Though this tool targets a platform specific file format, it is pure python code that is platform and endian independent.
