JSLint: control comments (selective ignore)

阅读更多关于 JSLint: control comments (selective ignore)

Does JSLint have anything like JavaScript Lint's control comments (e.g. /*jsl:fallthru*/ ) to make it ignore certain passages? napoleonss Put /*ignore jslint start*/ before and /*ignore jslint end*/ after the code to be ignored. Ex: function ignore(){ /*ignore jslint start*/ var x; var y; /*ignore jslint end*/ } Or export JsLint settings, define your IgnoreErrorStart/ IgnoreErrorEnd symbols and import. Edit Some folks may confuse this answer with JSHint. In that case, use these: /*jshint ignore:start*/  /*jshint ignore:end*/ Taken from https://stackoverflow.com/a/26012357

JSHint and jQuery: '$' is not defined

阅读更多关于 JSHint and jQuery: '$' is not defined

问题 The following JS: (function() { "use strict"; $("#target").click(function(){ console.log("clicked"); }); }()); Yields: test.js: line 5, col 3, '$' is not defined. When linted using JSHint 0.5.5. Any ideas? 回答1: If you are using a relatively recent version of JSHint, the generally preferred approach is to create a .jshintrc file in the root of your project, and put this config in it: { "globals": { "$": false } } This declares to JSHint that $ is a global variable, and the false indicates that

Android Studio's “expected resource of type” checks?

阅读更多关于 Android Studio's “expected resource of type” checks?

问题 Android Studio Beta (0.8) has a nifty new feature where it checks that some int parameters are not arbitrary integers, but rather have some properties. For example, calling something like: setContentView(R.id.textView1); will correctly report that R.id.textView1 is not a layout id (the message is "expected resource of type layout"). There are other cases of this peppered around. Understandably, this protection is lost as soon as you add your own methods into the mix, e.g. private void

in c: func(void) vs. func() [duplicate]

阅读更多关于 in c: func(void) vs. func() [duplicate]

This question already has an answer here: Is it better to use C void arguments “void foo(void)” or not “void foo()”? [duplicate] 6 answers When a C function does not accept any arguments, does it have to be declared/defined with a "void" parameter by the language rules? PC-Lint seems to have problems when there's nothing at all in the argument-list, and I was wondering if it's something in the language syntax that I don't know about. Edit: I just found a duplicate (back-dupe? it came first) question, C void arguments , which has more answers and explanations. void means the function does not

Turning off eslint rule for a specific file

阅读更多关于 Turning off eslint rule for a specific file

问题 Is it possible to turn off the eslint rule for the whole file? Something such as: // eslint-disable-file no-use-before-define (Analogous to eslint-disable-line.) It happens to me quite often, that in a certain file, I'm breaking a specific rule on many places which is considered OK for that file, but I don't want to disable the rule for the whole project nor do I want to disable other rules for that specific file. 回答1: You can turn off/change a particular rule for a file by putting the

Ignoring return values in C

阅读更多关于 Ignoring return values in C

问题 Lately, I started using lint for static code analysis. One of the warning I get sometimes is regarding this issue. Let's say for instance that I've got the following function: uint32_t foo( void ); And let's say that I delibertly ignore the return value of the function. To make the warning dissapear, one can write (void) foo(); My question is, what is the "proper" way to write code like this, should I continue as I always did, since the compiler doesn't complain about it, or should I use the

Compiler warning for function defined without prototype in scope?

阅读更多关于 Compiler warning for function defined without prototype in scope?

问题 [Question inspired by a comment thread at this answer.] As everyone knows, since C99 it's an error to call a function that hasn't been declared, preferably with a proper prototype. But, going beyond that, I want my compiler to warn me if I define a function without a prototype declaration in scope, presumably included out of the same header file that the callers are using. (Unless the function is static, in which case all of this is moot.) The reason should be obvious: If there's a prototype

What exactly does Android's @hide annotation do?

阅读更多关于 What exactly does Android's @hide annotation do?

问题 Lots of internal APIs in Android are marked @hide . What exactly does this do? Another answer says that it only hides the methods from Javadoc, but that you can use reflection to access them. That makes no sense though - if they are only hidden from Javadoc then you surely wouldn't need reflection to access them. In fact I've found that I don't. I can still call some @hide methods (maybe just static ones?) and the app compiles and runs fine as far as I can tell. I just get a lint error: Note
