阅读更多关于 In Eclipse, is it possible to find all methods in project that take a certain parameter type?

问题 So that's basically my question. I'm converting all methods ArrayLists to HashMaps in parameterized methods, but I don't want to convert all ArrayLists to HashMaps since there are a few that are used locally. This is more of a curiosity than anything, but it would be useful. So, in Eclipse, is it possible to find all methods in project that take a certain parameter type? 回答1: Press Ctrl + H or from menu bar Search - Search ... , then choose Java Search : Then click Limit To - Match locations

How can I set Chrome as default external browser in Eclipse for Mac?

阅读更多关于 How can I set Chrome as default external browser in Eclipse for Mac?

问题 I think that question is self-explained :-) When I browse to Application eclipse send me an error. 回答1: rubdottocom almost got it. The problem is, that the path contains spaces. If you write a new shell script with the following content: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome' $1 Eclipse can launch a new Chrome instance with it. Sadly, this way it is not possible to open a new tab in an already running instance, as the script exits with the following error message:

Text editor vertical lines on statements

阅读更多关于 Text editor vertical lines on statements

问题 In other text editors, such as Notepad++, if statements among other things had a vertical line connecting the if to the else , and the else to the end , which makes visual parsing much easier. Example (Vertical lines highlighted by black boxes): I was wondering if there was a way to do this in Visual Studio. 回答1: Have a look at the indent guides extension, this can do what I think you want. 回答2: This feature is now available as part of Visual Studio Productivity Power Tools. This is a free

Stepwise debugging of selected Python code

阅读更多关于 Stepwise debugging of selected Python code

问题 The essence: Using Spyder, it's possible to run parts of code by highlighting it and clicking F9 . This works with For Loops as well, but the problem (for me at least) is that it seems impossible to run the selected part step by step . I find this a bit strange since it's possible to run For Loops step by step under other cirmustances (and inspect the state of the variables at each step). Allow me to explain: The snippet below is an operation on two variables names = ['A', 'B', 'C'] and

Can I change the size of the Xcode IDE fonts?

阅读更多关于 Can I change the size of the Xcode IDE fonts?

问题 I'd like to change the font size of the "Groups & Files" panel of the Xcode IDE. I know how to change the "Fonts & Colors" in the preferences, but those (seem to) only affect the code window, not the rest of the IDE. Any ideas? Thanks! 回答1: I believe you can change the size of the Groups & Files pane by setting the PBXTableFontSize parameter in ~Library/Preferences/com.apple.Xcode.plist . This needs PBXTableFont to be set first to take effect. 1) Run defaults write com.apple.Xcode

Eclipse ignoring incorrect @Override annotations

阅读更多关于 Eclipse ignoring incorrect @Override annotations

问题 For some reason one of my eclipse installations is ignoring incorrectly set @Override annotations. For example, if I put @Override on a method that isn't overriden, it just completely ignores it. Any ideas on how to bring it back to a state where it will display an error for an incorrectly annotated method? 回答1: The definition of @Override changed slightly in Java 6 (and unfortunatly without proper documentation) wherein an @Override annotation on a method that implements an interface method

Is there a Javascript IDE that has nothing to do with a browser?

阅读更多关于 Is there a Javascript IDE that has nothing to do with a browser?

问题 Does anyone know of a program that lets you write javascript; then execute it - all the while having nothing to do with a browser? I don't want DOM manipulation, the equivalent of Console.Write is enough for me. I'm thinking of something along the lines of DrScheme - nice big code editing window, let's you run it, stop it. While all the other features (debugging, etc) would be wicked, they're not vital. (source: plt-scheme.org) 回答1: I've been doing some JavaScript work lately using Mozilla

How to include the percent character in the visual studio debugger command line arguments?

阅读更多关于 How to include the percent character in the visual studio debugger command line arguments?

问题 I want to debug a program in Visual Studio 2010 SP1 with an argument like: "file-%04d.jpg". But entering this string in Project Properties > Config Properties > Debugging > Command Arguments changes the "%04", resulting in argv[1] being set to: "file-[some unknown symbol]d.jpg". The percent character seems to be interpreted as an escape sequence which is not what I want. This does not happen in 2008. 回答1: %xx seems to be interpreted as an ascii escape. So %25 should result in a real %
