Why does Golang enforce curly bracket to not be on the next line?

问题 correct: if(true) { } incorrect: if(true) { } Why is this style enforced, does it have something to do with the language spec, or is it just because they prefer one style over another ? 回答1: Why are there braces but no semicolons? And why can't I put the opening brace on the next line? Go uses brace brackets for statement grouping, a syntax familiar to programmers who have worked with any language in the C family. Semicolons, however, are for parsers, not for people, and we wanted to

Purpose of Curly Brace Usage of C Code found in Linux (include/linux/list.h)?

廉价感情. 提交于 2019-12-07 09:20:05
问题 I came across the following code within Linux (include/linux/list.h). I'm confused about line 713. In particular, I don't understand ({ n = pos->member.next; 1; }). What is the curly braces doing? Why is there a '1' in this statement? If someone could explain this particular line it would be much appreciated. Note, I don't need an explanation of how link lists and #defines work, etc. 704 /** 705 * hlist_for_each_entry_safe - iterate over list of given type safe against removal of list entry

问题 How do I highlight operators/parentheses/brackets/etc. in VIM? I'm not interested in coloring matching or unmatching parentheses/brackets. I've tried ":hi cBracket/whatnot guifg=something" and ":hi Operator/cOperator guifg=something" but these don't seem to affect anything. 回答1: There are two parts to Vim syntax coloring: the syn command and the hi command. As far as I understand, you use syn to define syntax. For example: syn match parens /[(){}]/ Then you use hi to tell Vim how to highlight

Add curly braces to ggplot2 and then use ggsave

久未见 提交于 2019-12-05 15:17:25
问题 So this is very relevant to this question and this answer is an excellent solution. The problem is that when I try to export the plot using ggsave the curly braces aren't present. example: library(ggplot2) library(grid) library(pBrackets) x <- c(runif(10),runif(10)+2) y <- c(runif(10),runif(10)+2) the_plot <- qplot(x=x,y=y) + scale_x_continuous("",breaks=c(.5,2.5),labels=c("Low types","High types") ) + theme(axis.ticks = element_blank(), axis.ticks.length = unit(.85, "cm")) the_plot grid

Wrapping multiple statements in braces

问题 Is there a keyboard shortcut in Visual Studio 2010 (I'm using ReSharper 6.1 also) that will allow me to surround a selected block of text with curly braces? I tried "Surround With..." (Ctrl+K, Ctrl+S), but I didn't see an option in the list to choose curly braces as the surrounding element. The common use case for this is that I'll have an if-statement like the following: if (conditional) statement1; // the rest of the program I'll realize that there are some additional tasks that need to be

Possible Duplicate: Escape curly brace '{' in String.Format c# has a String.Format method that allows you to format a string but inserting params with the tokens {0} {1} I am trying to create a simple json string which requires curly brackets to be in the string, and so it is breaking the formatter String.Format("{ foo:'{0}', bar:'{1}' }", foo, bar); Adding an escape before the braces did not help Throws a exception saying my string is incorrectly formatted, anyone know how to get around this? You can escape the braces by doubling them up in your format strings: string.Format("{{ foo: '{0}',

How to make custom keyword statement

余生长醉 提交于 2019-12-04 20:26:36
How would I go about making a function that uses braces like if/for/while statements? I'm referring to this as a 'keyword statement' because I don't know what else to call it. Meaning, for example, if I wanted to make a 'repeat' function: repeat(3) { //do something } I guess a better question is, is this possible? If so, how would one go about doing this? You might define a range similar to a python range: // Range // ===== #include <iterator> #include <utility> template<typename T> class Range { public: typedef T value_type; public: class iterator { public: typedef typename std::forward
