“Curly Braces” are used in Python to define a dictionary. A dictionary is a data structure that maps one value to another – kind of like how an English dictionary maps a word to its definition. Python: dict = { “a” : “Apple”, “b” : “Banana”, } They are also used to format strings, instead … Read more
Just configure Smart Keys as follow: IDE Settings > Editor > General > Smart Keys > Surround selection on typing quote or brace. From the IntelliJ built-in help: If this check box is selected, the selected text on typing a quote, double-quote or brace, will be surrounded with these characters. If this check box is … Read more
Legacy code needed { } in order to do declarations at all In C89, you couldn’t just do int i; anywhere; declarations were only valid at the beginning of blocks. So: a = 1; int i; /* error */ i = 2; …wasn’t valid, but a = 1 if (e) { int i; …was fine, … Read more
Curly braces create dictionaries or sets. Square brackets create lists. They are called literals; a set literal: aset = {‘foo’, ‘bar’} or a dictionary literal: adict = {‘foo’: 42, ‘bar’: 81} empty_dict = {} or a list literal: alist = [‘foo’, ‘bar’, ‘bar’] empty_list = [] To create an empty set, you can only use … Read more
See the section on Substring removal on the parameter expansion page of the bash-hackers’ wiki: ${PARAMETER#PATTERN} and ${PARAMETER##PATTERN} This form is to remove the described pattern trying to match it from the beginning of the string. The operator # will try to remove the shortest text matching the pattern, while ## tries to do it … Read more
Curly braces are used to explicitly specify the end of a variable name. For example: echo “This square is {$square->width}00 centimeters broad.”; So, your case is really a combination of two special cases. You’re allowed to access class variables using curly braces and like so: $class->{‘variable_name’} // Same as $class->variable_name $class->{‘variable’ . ‘_name’} // Dynamic … Read more
Curly braces are not required, but they might come in handy to introduce a new declaration space. This behavior hasn’t changed since C# 1.0 as far as I know. The effect of omitting them is that all variables declared somewhere inside the switch statement are visible from their point of declaration throughout all case branches. … Read more
Under Tools → Options → Text Editor → C# → Formatting → New Lines are the rules for the open brace on each case (new methods, control blocks, etc), maybe you can find the one you want there.
The only purpose of the extra braces is to provide scope-limit. The List<PExp> copy will only exist within those braces, and will have no scope outside of them. If this is generated code, I assume the code-generator does this so it can insert some code (such as this) without having to worry about how many … Read more
Go Preferences -> Settings Search for C_Cpp.clang_format_fallbackStyle Click Edit, Copy to Settings Change from “Visual Studio” to “{ BasedOnStyle: Google, IndentWidth: 4 }” e.g. “C_Cpp.clang_format_fallbackStyle”: “{ BasedOnStyle: Google, IndentWidth: 4, ColumnLimit: 0}” btw ColumnLimit: 0 is helpful too, because google limit will break your code to next line when you do not need it. If … Read more
