#!/usr/bin/env python import os, sys, subprocess, time while True: print subprocess.call("xsel", shell=True); time.sleep(1); Takes an entry from the clipboard and prints it, every 1 second.

Is it better, from a performance standpoint, to use "Example1"? I'm assuming that "Example2" would create a new string on the heap in each iteration while "Example1" would not... Example1: StringBuilder letsCount = new StringBuilder("Let's count! "); string sep = ", "; for(int i=; i< 100; i++) { letsCount.Append(i + sep); } Exa...
def checkCache(cachedText): for line in open("cache"): if cachedText + ":" in line: print line open("cache").close() else: requestDefinition(cachedText) This code searches each line of a file (cache) for a specific string (cachedText + ":"). If it does not find the specific stri...
I have trouble understanding the compilers. The following code does work in UNIX under g++, but under VC++ it would not even compile. Anyone can provide valid reasons why? #include <stdio.h> #include <iostream> #include <string.h> using namespace std; int main() { string tmp_nw_msg, crc_chksum, buffer; cout << "Enter the str...
I have some fairly simple (at least when you skip error checking, event stuff, et cetera) parameter classes. They are "assembled" kind of like this: public interface IParameter { Type ValueType { get; } object Value { get; set; } } public interface IParameter<TValue> : IParameter { new TValue Value { get; set; } } public a...
Hi, I might be asking this question incorrectly but what I would like to do is the following: Given a large String which could be many 100s of lines long match and replace a word exactly and make sure it does not replace and match any part of any other String. For example : Strings to Find = Mac Apple Microsoft Matt Damon I.B.M. Hur...
In Python I have four strings that include the formatting of a list: line1 ="['a.b.c','b.c.a','c.d.e']" line2 ="['def','efg']" line3 ="['f']" line4 ="['g']" How do I merge them all so I get a valid Python list such as: SumLine = ['a.b.c','b.c.a','c.d.e','def','efg','f','g'] ...
Can anyone please tell me how to multiply two number arrays in C? The number arrays are basically derived from two strings containing digits. eg: 123456 and 132465. Edit: I had two string as S1 = "123456" and S2="132546". I then converted these two strings into array of ints i.e. int IS1[6] and IS2[6] so that IS1[1] = 1, IS1[2] = 2......
In C#, strings are reference type but behaves like value type. e.g. string str = "I am a string"; str.Replace("am", "was"); //str still contains same value, //i want it to make "I was a string" I know i can do this by str = str.Replace("am", "was"); But i don't want to re-assign it. Is there anyway to make them behave like Refere...
I'm looking for a nice template engine or short piece of code to expand Ant-like variables in a string in Java. Example: String result = expand ("${firstName} ${familyName}", map); It should at least support java.util.Map but something that can handle beans or recursive lookups or lookups in a list of maps/objects would be welcome, to...

Due to the sheer annoyance of figuring out what to Google, I've decided to risk what any reputation I had to ask this rather simple question. As PEP8 suggests keeping below the 80 column rule for your python program, how can I abide to that with long strings, i.e. s = "this is my really, really, really, really, really, really, really l...

I'm pretty new to Python and am completely confused by .join() which I have read is the preferred method for concatenating strings. I try: strid = repr(595) print array.array('c', random.sample(string.ascii_letters, 20 - len(strid))) .tostring().join(strid) and get something like: 5wlfgALGbXOahekxSs9wlfgALGbXOahekxSs5 Why does...
