问题 PHPStorm 8.0.3 for Mac wants to tell me about missing semicolons in my JavaScript. I don't want PHPStorm to do this. This blog page says... Built-in inspections help you detect errors and potential problems, from obvious ones like a missing semicolon ... Later, the blog indicates that "The full list of built-in inspections is available in Preferences | Inspections", but I can find no mention of semicolons in any of the subcategories of the 14 inspection categories. Is PHPStorm intransigent

问题 The code below works perfectly, however, PyCharm complains about syntax error in forward(100) #!/usr/bin/python from turtle import * forward(100) done() Since turtle is a stanrd library I don't think that I need to do additional configuration, am I right? 回答1: The forward() function is made available for importing by specifying __all__ in the turtle module, relevant part from the source code: _tg_turtle_functions = [..., 'forward', ...] __all__ = (_tg_classes + _tg_screen_functions + _tg

问题 When I am in a .java file the unused code is usually grayed out or has a green underline saying this code will probably (probably because of some weird JNI/Reflection corner cases) be unused. But I have this project with thousands of Java files and I want to find ALL INSTANCES of such probable-unused codes. How can I do that in IntelliJ IDEA? 回答1: Just use Analyze | Inspect Code with appropriate inspection enabled ( Unused declaration under Declaration redundancy group). Using IntelliJ 11 CE

问题 In the tracer callback set with python's sys.settrace() , I can get the function name, line number, etc. Now I want to know whether the current function being traced is called in a loop by its caller. Is there a way to do this? 来源： https://stackoverflow.com/questions/30770628/how-can-i-tell-if-a-function-is-called-in-a-loop-within-pythons-tracer-function

问题 Okay I've finally switched to PHP7. My code is a bit old and will be refurbished. Some of the problems are: class MagicClass function MagicClass(){ //etc } Which gives an deprecation warning during execution: Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; MagicClass has a deprecated constructor in This is good: class MagicClass function __construct(){ //etc } How can I get PhpStorm code inspection to warn me for such errors in my

问题 IntelliJ is suggesting to import com.sun.istack.internal.NotNull the @NotNull annotation (which is wrong) in the following program: public class Test implements Comparable<Test> { @Override public int compareTo(@NotNull Test o) { return 0; } } When trying the correct import com.intellij.annotations.NotNull (I think) it looks like it can't find the class: 回答1: You can Alt+Enter on the warning before you add the annotation, press Right, choose Edit Inspection Settings, then Configure

问题 I've read that the object's __ enter__() and __ exit__() methods are called every time 'with' is used. I understand that for user-defined objects, you can define those methods yourself, but I don't understand how this works for built-in objects/functions like 'open' or even the testcases. This code works as expected and I assume it closes the file with __ exit__(): with open('output.txt', 'w') as f: f.write('Hi there!') or with self.assertRaises(ValueError): remove_driver(self.driver) # self

问题 I have inherited a bunch of Python files and looking for a way to get an understanding of what is going on within them by collecting information about all the functions that have been defined and called within those files. Example of a file (MainModule.py): Import module1 Import module2 Import module3 ... Def func1(): ... Def func2(): ... result1 = Module1.funcX(args) result2 = Module2.funcY(args) ... By looking into this file, I want IDE to report what functions have been defined within this

问题 I know I can suppress warnings from IntelliJ IDEA inspections like that: @SuppressWarnings("CollectionDeclaredAsConcreteClass") public PropertiesExpander(Properties properties) { this.properties.putAll(properties); } For person from outside it may not be clear for which tool this suppression is needed. PMD uses prefixes for that: @SuppressWarnings("PMD.UnusedLocalVariable") FindBugs uses dedicated annotation: @SuppressFBWarnings("NP_NONNULL_FIELD_NOT_INITIALIZED_IN_CONSTRUCTOR") Is there any
