Abandoned Resource String Detection

This command line program detects unused resource strings in an iOS or OS X application.

Updated to Swift 3, thanks to @astaeck on Oct-17-2016

Usage

Open a Terminal to the directory which contains the AbandonedStrings executable, and run the following command:

$ ./AbandonedStrings /Users/your-username/path/to/source/code

What to expect

If a .strings file contains…

"some_string_identifier" = "Some Display Text";

…this program will consider that resource string to be abandoned if…

"some_string_identifier"

…is not found in any of the source code files (namely, files with a .h, .m, .swift or .jsbundle extension).

More details

This program searches through the source code files in an iOS app project, looking for resource strings (in a .strings file) whose identifiers are not referenced by the application's source code.

The search logic does not take into account if code is commented out, so it won't be as reliable if your application has a lot of commented-out code.

It also does not try to determine the context in which string identifiers are used, such as whether or not the string is being used to look up a localized string value or if it just happens to match a resource string identifier by coincidence.

Also, this program is ineffective if resource string identifiers are referenced via constants or dynamically constructed.

Disclaimer

As noted above, this program uses a simple heuristic and is not guaranteed to produce perfect results for every codebase.

    Updated to Swift 3 and added Storyboard as optional argument

    This pull request converts the project to the latest Swift 3 version. Furthermore it adds the possibility to enter "storyboard" as last optional command line argument to enable also the search for identifiers which are used inside the visual files. You can also add more root directory paths.

    You're a gentleman & a scholar - thanks for the great tool!

    This PR:

    • makes main.swift executable
    • allows for running from the command line per the docs (for those not used to running swift that way)

  • Parallelize + add

    Parallelize + add "write" option

    Hi there, thanks for making this! It was missing 2 things I needed:

    1. it was really slow (I have a large source-base), because it was confined to one thread. It is now parallelized so you can use all your CPU cores
    2. I want this to (destructively) modify my strings files, so I added a "write" parameter. If "write" is present, it'll update the strings files. I made separate commits for (1) and (2). All the best -tim

  • No results when '.strings' files are not UTF8 encoded

    No results when '.strings' files are not UTF8 encoded

    Don't know if you've had this problem, but I got no results running abandoned-strings on my source. Turned out it was thecontentsOfFile method failing due to the encoding of the .strings files not being UTF8 encoded. I changed the method thusly to fix it.

    func contentsOfFile(filePath: String) -> String {
    do {
        let usedEncoding = UnsafeMutablePointer<NSStringEncoding>()
        return try String(contentsOfFile: filePath, usedEncoding: usedEncoding)
    }
    catch { return "" }
}

  • Crash due to force unwrapping

    Crash due to force unwrapping

    Seeing quite a few crashes here: let endIndex = lineWithoutFirstQuote.index(of:"\"")!

    It would be best to remove all force unwrapping and make functions like extractStringIdentifierFromTrimmedLine return optional strings.
