Splitting Codes into Classes

I’m happy to say I’m a heavy VIM user, but it would not be a proud thing for me if it caused troubles to other people I’m working with. Yes, I have to put .*.sw* in the .gitignore file, but I’m talking about something else: I tend to create very long file to edit. For example, in the project I’m currently working on, the ViewControllers.swift file has more than 3000 lines.

While it’s super convenient for me to edit everything in the same file using / and * to search for contents, and using H and L to bprev and bnext between things like AppDelegate.swift, ViewControllers.swift and Const.swift, it would a disaster for someone else to read the code. So if I’m working on a project or a module, I’d work in a way that I’m comfortable with, but when it’s time to collaborate with other developers, I need to break things up in to ViewControllers/MyClass1.swift etc.

To automate this, I created a swift-split script in my Github script repo, which was previous named source-split and perhaps I’ll rename it back after I add support to other formats. Basically it splits source file by classes and put them inside a directory that is named after the original filename, e.g. split MyClasses.swift to MyClasses/MyClass1.swift, MyClasses/MyClass2.swift etc. For now, it’s still under development at the time being, and I’m going to update this post after I make any progress:

USAGE:
	swift-split.php SOURCE_FILE1 SOURCE_FILE2 ...
NOTES:
	By default, OUTPUT_DIRX is the main part of the filename.
	Currently only SWIFT source files are supported.
ABOUT SWIFT SPLITTER:
	Nested classes and structs will not be splitted.
	Currently the 'import' part is not done correctly. Please modify this script to get it work.

As mentioned in the README, you need to modify the script to correctly apply the import list. You can also add them manually after splitting.
