parentheses

In one of my scripts, I need to use variables that contain parenthesis inside IF statements, but either the string is missing a closing parenthesis or the script exits prematurely with * was unexpected at this time (not actually an asterisk), depending on the scenario. Example @echo off SET path=%programFiles(x86)% echo Perfect output: %path% IF NOT "%path%" == "" ( REM Variable is defined echo Broken output: %path% ) pause >nul Output Perfect output: C:\Program Files (x86) Broken output: C:\Program Files (x86 I think/know that this is because it thinks the closing parenthesis in C:\Program

I know the difference in purpose between parentheses () and curly braces {} when grouping commands in bash . But why does the curly brace construct require a semicolon after the last command, whereas for the parentheses construct, the semicolon is optional? $ while false; do ( echo "Hello"; echo "Goodbye"; ); done $ while false; do ( echo "Hello"; echo "Goodbye" ); done $ while false; do { echo "Hello"; echo "Goodbye"; }; done $ while false; do { echo "Hello"; echo "Goodbye" }; done bash: syntax error near unexpected token `done' $ I'm looking for some insight as to why this is the case. I'm

Would like to turn text with nested parenthesis to a nested array. Here is an example output from an NLP parser: (TOP (S (NP (PRP I)) (VP (VBP love) (NP (NP (DT a) (JJ big) (NN bed)) (PP (IN of) (NP (NNS roses))))) (. .))) (orig: I love a big bed of roses.) Would like to turn this into a nested array so it will look sg like this TOP S NP PRP I VP VBP Love etc. Found this php curly braces into array but that is not a nested array explanation by code: <?php class ParensParser { // something to keep track of parens nesting protected $stack = null; // current level protected $current = null; //

I'm implementing a pretty-printer for a JavaScript AST and I wanted to ask if someone is aware of a "proper" algorithm to automatically parenthesize expressions with minimal parentheses based on operator precedence and associativity . I haven't found any useful material on the google. What seems obvious is that an operator whose parent has a higher precedence should be parenthesized, e.g.: (x + y) * z // x + y has lower precedence However, there are also some operators which are not associative, in which case parentheses are still are needed, e.g.: x - (y - z) // both operators have the same

If I for example type "Integer." and then hit CTRL+SPACE, and now choose "valueOf" from the list, Eclipse always adds "()" after the function name. That is really annoying to me because often times I have an already existing statement and want to wrap a function around it. Example: I want to change String x = "hello world"; to String x = StringManipulator.uppercase("hello world"); If I write String x = StringManipulator."hello world"; and hit CTRL+SPACE on the dot character, it inserts String x = StringManipulator.uppercase()"hello world"; Is there any way to fix this behaviour? I don't need
