curly-braces

问题 In Java the following is completely valid: if (x == null) Y(); else Z(); I personally don't like it at all. I like all my IF statements to have braces: if (x == null) { Y(); } else { Z(); } The eclipse formatter is wonderful and can beautify my code in many other ways. Is there a way to have it add the braces to IF statements? 回答1: Under "Preferences": Java > Editor > Save Actions 1) Check "Additional actions" 2) Click "Configure…" 3) Go to the "Code Style" tab 4) Check "Use blocks in if

问题 In-class initializers (C++11 feature) must be enclosed in curly braces or follow a = sign. They may not be specified inside parenthesis. What is the reason for this? 回答1: I am not 100% positive about this, but this might be to prevent a syntax ambiguity. For example, consider the following class: class BadTimes { struct Overloaded; int Overloaded; // Legal, but a very strange idea. int confusing(Overloaded); // <-- This line }; What does the indicated line mean? As written, this is a

问题 I'm dealing with a line such : mkdir -p "$DEST_ROOT_PATH/"{"$DEST_DIR1","$DEST_DIR2", ..., "$DEST_DIRN"} This line is quite long. I want to cut it so its width will fit into a 80 columns line. I tried to escape an end of line with a backslash, but space alignement breaks the expansion : $ echo "ha"{a,b,\ > c} ha{a,b, c} 回答1: You could use this disgusting hack. echo "ha"{a,b,\ > ` `c} It opens a subshell with nothing in it, but gets processed before the expansion so the expansion just sees an

问题 I have a CSS file and a PHP file that I received from an overseas outsource partner. He prefers curly braces on a new line, while I am rather Old School and prefer the curly brace on the same line as the declaration. How can I use Bash and/or sed or other command-line tools to revert curly braces from this new style and into this older style? EDIT : Someone wanted to see an example. Okay, here goes: NEW SCHOOL STYLE I DO NOT LIKE body { padding:4px; margin:3px; } OLD SCHOOL I PREFER body {

问题 I'm trying to find out a name for code that is surrounded by double curly braces in Laravel. Do they even have a name. Are they known as double curly braces in all languages. The reason I want to know is that I still do not quite understand the scope of them. I know a lot of languages use them, but what is their name? For instance; if I want to know why double curly brace variables don't work in a Laravel @include; how do I find out? Another example is that I cannot add a tag on stack

问题 I've just started using emacs, and there's one feature I'd really like, and searching around a bit was fruitless. I hope someone else has done this because I don't want to learn elisp just yet. void foo()<cursor> I would like typing an "{" to cause this to happen void foo(){ <cursor> } I would like this to only happen in cc-mode, and only at the end of a line when not in a string/comment/etc The first thing that came to mind was rebinding "{" to do this always(I could figure out how to do
