C# Regex match anything inside Parentheses

江枫思渺然 提交于 2019-11-29 02:24:07
问题 I want to match anything inside parentheses but the result must exclude the parentheses as well. Examples: Initialize(P90W) Brake(45X) Result: 990W 45X note results without the Parentheses. I've been trying to make this work but to no avail I tried a few variations but I know it's a simple thing I'm missing and I don't want to go using Replace to achieve it. var item = "Brake(45X)" Regex searchTerm = new Regex(@"\((.*)\)"); var value = (searchTerm.Match(item).Groups.Count > 0) ? searchTerm

parentheses in Python Conditionals

问题 I have a simple question regarding the use of parentheses in Python conditional statements. The following two snippets works just the same but I wonder if this is only true because of it's simplicity; >>> import os, socket >>> if ((socket.gethostname() == "bristle") or (socket.gethostname() == "rete")): ... DEBUG = False ... else: ... DEBUG = True ... >>> DEBUG and now without parentheses >>> import os, socket >>> if socket.gethostname() == "bristle" or socket.gethostname() == "rete": ...

Complex Git branch name broke all Git commands

I was trying to create a branch from master with the following command, git branch SSLOC-201_Implement___str__()_of_ProductSearchQuery when Git suddenly stopped responding. I suspect the unescaped () are to blame, somehow. Now, whenever I try to run any Git command, I get the same error: git:176: command not found: _of_ProductSearchQuery with the number after git increasing every time I type a command. Can anyone explain what happened? And how do I get back to normal? I'd like to delete that branch, but how can I do that? jub0bs Problem Can anyone explain what happened? [...] I'd love to be

How to select between brackets (or quotes or …) in Vim?

浪子不回头ぞ 提交于 2019-11-28 14:56:19
I'm sure there used to be a plugin for this kinda stuff, but now that I need it, I can't seem to find it (naturally), so I'll just ask nice and simple. What is the easiest way to select between brackets, or quotes, or generally a list of matching characters? write ( *, '(a)' ) 'Computed solution coefficients:' For example, here I'd like to select (a) , or Computed solution coefficients: . I'm not interested in multiline, just cases which occur on one line. Tim Whitcomb Use whatever navigation key you want to get inside the parentheses, then you can use either yi( or yi) to copy everything

Find String Inside Outermost Parenthesis

旧时模样 提交于 2019-11-28 14:36:00
Say that I have a string which contains both multiple sets and nesting of parenthesis. I want to extract only the string in the first parenthesis encountered, including whatever nested parenthesis it contains. For example: this (is(maybe)) a test (and maybe not) I want to extract: is(maybe) I believe this can be accomplished without the use of regexes, by which I can easily do it. So my question is how can this be accomplished without regexes? Pseudo code: iterate over chars if char is ( increment counter store position of first ( only if char is ) decrement counter if counter == 0 use index

What is the point of wrapping JavaScript statements in parentheses?

与世无争的帅哥 提交于 2019-11-28 13:05:59
I have discovered that wrapping different statements in parentheses will return the last one: (34892,47691876297,2000) => 2000 ('test',73,document.createElement('p')) => <p></p> And I also found out that all the statements are executed anyway: (console.log('test'), console.log('test2'), console.log('test3'), 6) Will log: test test2 test3 And the result will be 6. However, I've also found that some statements can't be used: (throw new Error(), 10) => SyntaxError: Unexpected token throw (if (1) console.log('test'), 5) => SyntaxError: Unexpected token if So, what is the point of this parenthesis

Javascript function in setInterval

问题 I have the following code: var foo=5; var los= function (){ alert(foo);}; setInterval(los, 1000); which works correctly. If I change it to : var los= function (){ alert(foo);}; setInterval(los(), 1000); it only executes once with no errors in console. Can someone explain me why this happens when I include the parentesis after los in the setInterval function? 回答1: Keep in mind that in JavaScript a function is an object, passed around like any other variable. So this is a reference to the

C# Regex - How to remove multiple paired parentheses from string

浪尽此生 提交于 2019-11-28 09:12:10
I am trying to figure out how to use C# regular expressions to remove all instances paired parentheses from a string. The parentheses and all text between them should be removed. The parentheses aren't always on the same line. Also, their might be nested parentheses. An example of the string would be This is a (string). I would like all of the (parentheses to be removed). This (is) a string. Nested ((parentheses) should) also be removed. (Thanks) for your help. The desired output should be as follows: This is a . I would like all of the . This a string. Nested also be removed. for your help.

Do parentheses make a difference when determining the size of an array?

The following program prints the same number twice on gcc 4.8.2: #include <stdio.h> int main() { char a[13]; printf("sizeof a is %zu\n", sizeof a ); printf("sizeof(a) is %zu\n", sizeof(a)); } According to this reddit post , gcc is not standard-conformant in this respect, because a parenthesized expression is not on the list of exceptions for when array-to-pointer decay does not happen. Is this guy correct? Here is the relevant standard quote: Except when it is the operand of the sizeof operator or the unary & operator, or is a character string literal used to initialize an array of character
