NSInvalidArgumentException issue

[cfjedimaster]

I'm getting this error when running appledoc on a set of code:

Oops, something went wrong... NSInvalidArgumentException: -[__NSCFString appendString:]: nil argument @ 0 CoreFoundation 0x00007fff95ea825c __exceptionPreprocess + 172 @ 1 libobjc.A.dylib 0x00007fff8b5b2e75 objc_exception_throw + 43 @ 2 CoreFoundation 0x00007fff95ea810c +[NSException raise:format:] + 204 @ 3 CoreFoundation 0x00007fff95e77def mutateError + 159 @ 4 appledoc 0x000000010cd34a3d appledoc + 84541 @ 5 appledoc 0x000000010cd3c293 appledoc + 115347 @ 6 appledoc 0x000000010cd343bc appledoc + 82876 @ 7 appledoc 0x000000010cd33e55 appledoc + 81493 @ 8 appledoc 0x000000010cd30f94 appledoc + 69524 @ 9 appledoc 0x000000010cd2ecb3 appledoc + 60595 @ 10 appledoc 0x000000010cd302c1 appledoc + 66241 @ 11 appledoc 0x000000010cd2ff6a appledoc + 65386 @ 12 appledoc 0x000000010cd2fba1 appledoc + 64417 @ 13 appledoc 0x000000010cd2e960 appledoc + 59744 @ 14 appledoc 0x000000010cd23540 appledoc + 13632 @ 15 appledoc 0x000000010cd21d57 appledoc + 7511 @ 16 appledoc 0x000000010cd21ec0 appledoc + 7872 @ 17 appledoc 0x000000010cd2204b appledoc + 8267 @ 18 appledoc 0x000000010cd21304 appledoc + 4868

When I increase the verbosity, I get this rightbefore (and I'm going to rename some stuff due to NDA-lameness):

Registering typedef block AdobeFooNetworkResponseCompletion... Matched AdobeFooNetworkResponseProgress typedef block definition at line 55.

The code in question is the last line of the file:

typedef void(^AdobeFooNetworkResponseProgress)(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpected);

Which as far as I know looks fine to me.

[ramonpoca]

I have been able to reproduce with a simple .h file:

          typedef void (^Foo)(Bar*);

and calling appledoc -p X -c X file.h Crashes at GBObjectiveCParser.m:matchTypedefBlockDefinitionForProvider line 503.

Seems that line 503 assumes that a name will follow "Bar*", consumes it and the next loop has already consumed over the ";".

I'm stumbling upon the same error as everybody else here. Anybody found a solution/workaround yet?

Blocks are not supported at present. Previously appledoc ignored them, but seems like latest changes broke that.

[he1ko]

first ... I love your work as well as my beautyful documentation made by appleDoc. ;-)

Nevertheless I run into the same errors on block definitions. Can you name a GIT revision in which blocks are properly ignored? I would prefer building my documentation for the whole project and editing the final HTML files where block explanations are missing later.

Thanks in advance!

[he1ko]

Sorry, if I might not have noticed the right entry in your docs - I think for the moment it would be helpful to provide a source comment type like

/**
 * ###PLEASE_IGNORE###
 */
typedef void(^myMethodCompletionHandler)(BOOL*);

I would add it above block definitions and their usage.

[tomaz]

Not sure which commit caused regression. If you're in time, try git bisect - start with one of older commits - ar least prior to beginning of this issue. Then it should take couple iterations until it'll point out regression...

[he1ko]

Thank you. No problem, docs are important for me - in the current project more than ever… so I’ll have the time. If I find a useful revision ignoring blocks, I’ll reply this to you so you can post it in the bug report, if you like.

bye…

Did anyone determine that which revision works? I'm on appledoc version: 2.2 (build 963) as well and seeing this issue. My other teammates are on v2.2 as well, not sure if they have the latest build, but aren't seeing an error with the same code we are trying to document.

I also tried the appledoc22 in brew but that one doesn't compile for me with an error about garbage collection is no longer supported.

[he1ko]

I haven’t found a revision that works both for ARC and with blocks.

[tomaz]

Latest master should compile on ARC - for compile with Xcode 5.1+. Not sure of homebrew status, I'm not managing that.

Block syntax is still not supported.

[sseyod]

I'm seeing the problem with Block syntax as well. Please fix ASAP :-D

[tomaz]

Let's hope for community contribution then ;)

[sseyod]

Hi tomaz,

As requested :) I've run this through XCode, and by commenting-out the code in GBObjectiveCParser.m from lines 490 to 517, the code then seems to work 100% OK (from my limited testing).

  /*
    if (![[self.tokenizer lookahead: 2] matches: @"void"]) {

... ... ... [values addObject: newArg];

             *consume = NO;
         }];
    }

*/ I hope this helps!

Pete

[sseyod]

My particular problem code was of this form:

typedef void (^TCallWhenDone) ()

[bochos]

same problem with: typedef void (^IconClickBlock)(NSInteger); comment out generates documentation

[JeremyBlastMotion]

Similar to above - but with a more complete call stack:

It looks like in GBCommentsProcessor.m: (BOOL)matchesObject:(id)object - is passed in a GBEnumConstantData object. This class does not match any of the handled "if" conditions and also does not implement the "methodSelector" message - which causes the app to crash.

I resolved the issue locally by adding another else if to Processing/GBCommentsProcessor.m - matchesObject: around line 52.

else if ([object isKindOfClass:[GBEnumConstantData class]]) return NO;
