I got result that a file, which was imported ONLY in project's .pch file, was an unused import. This is a false positive, app wouldn't compile without it.

My project contains a mixture of Objective-C and C++ code, wonder if you scan also .mm files. I took a look at some fui file, found this " k.path.gsub(/.h$/, '.m' ", which looks a bit suspicious.

fui does not search in .xib and .storyboard files for used classes. As result those classes marked as unused.

I was looking for a tool that can help me to remove unused #import at top of a class.

This utility is nice, but it does not "find unused import", but find unused class (as stated in the readme).

Is it possible/expected to have the fui command tell :

SomeClass.m:14 unused import of SomeOtherClass.h

?

You can use the image scanning and useless resources related to the swift, useless code scanning?

Hello
Dustin Barker，Could I not scan files larger than 500kb? My project sdk contains more than 500kb framework, no scan out.thanks!

I'm getting this error when I try to use fui:

/usr/bin/fui:19:in `load': /Library/Ruby/Gems/1.8/gems/fui-0.2.0/bin/fui:9: syntax error, unexpected ':', expecting $end (SyntaxError)
flag [:p, :path], desc: 'Path to search', default_value: Dir.pwd
                       ^
    from /usr/bin/fui:19

Categories marked as unused in all source code.

https://developer.apple.com/library/ios/documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/CustomizingExistingClasses/CustomizingExistingClasses.html

For example, some of these forward declarations are no longer unused:

#import <Foundation/Foundation.h>

@class Foo;
@class Bar;
@protocol Bar;

@interface Qux

@property (nonatomic, strong) Baz *baz;

@end

Probably via customClass? See http://iosdevweekly.com/issues/130.

I know almost nothing about Ruby. When I run fui I see the following
/usr/bin/fui:19:in `load': /Library/Ruby/Gems/1.8/gems/fui-0.2.0/bin/fui:9: syntax error, unexpected ':', expecting $end (SyntaxError)
flag [:p, :path], desc: 'Path to search', default_value: Dir.pwd

My macbook have ruby 1.8.7. Help appreciated.

Travis-CI is no more. Inspire from dblock/ruby-enum#34 for example.

There're .xib files associated with an unused view that should be deleted.

When use fui find in project directory in terminal , no content appear in console . How can I know the command is executing ? And does it working ?

Hey, I ran this against an objective-c code base, but no matter how many unused imports I add, I don't get any results. I turned on verbose, and it is scanning the files that have unused imports. This is an xcode 5.1.1 (ios7) project. Thoughts?

Contribute a RELEASING doc ala https://github.com/dblock/strava-ruby-client/blob/master/RELEASING.md and release next version.

execute fui find command. its list all files in the current folder, not the unused class file

You can write a responder (see http://stackoverflow.com/questions/6741746/how-do-responder-chain-works-in-iphone-what-are-the-next-responders) that doesn't get included into anything.

We have this:

#import "ARArtworkViewController.h"

@interface ARArtworkViewController (ButtonActions)

@end

@implementation ARArtworkViewController (ButtonActions)

- (void)tappedSomething:(SomeView *)sender
{

}

This causes a false positive.

We could go as far as edit the xcproj file and remove the files being deleted.

For example, a class named "Test.h" and "Test.mm".
"Test.mm" import "a.h"

However, "a.h" will be marked as unused.

...as in
#include "header.h"

Would be cool if we could run fui from within XCode, so a plugin would be great. Thanks.

when i try to find all unused classes, it tells me that one of them is not used when it clearly is. could it be that it's because the import for it is in a class extension, and so fui doesn't believe it's being imported at all? i typically have MyClass.h and MyClass_Private.h, and this private header which is a class extension is where it's imported

Hi there,
After I type 'fui' in terminal, I get an error:
-bash: /usr/local/bin/fui: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory

It seems that this tool has dependency of ruby 2.3, but my system ruby version is not 2.3.

Anyone please help me? Thanks.

Hello,

I am running fui with
fui -v --path=src --ignore-path=src/Pods find
but end up with an error
error: undefined local variable or method `project_path' for #<Fui::Project:0x00007f9731a5c8d0>

What is the reason for such error and is there a workaround known?

Cheers, Andy

Does it support swift 2.3 / swift 3 ?
It would be really nice.

I noticed that if you have a file that is imported and accidentally missing a space

 #import"filename.h"

it is not counted and therefore the file can be marked as unused even if it is. The #import search should ideally be a regex that supports any amount of spaces.
