foo.replace(/,([^,]*)$/, ‘ and $1’) use the $ (end of line) anchor to give you your position, and look for a pattern to the right of the comma index which does not include any further commas. Edit: The above works exactly for the requirements defined (though the replacement string is arbitrarily loose) but based on criticism … Read more

By default you can use the methods of the Java String object: #set( $a = “Hello” ) #set( $b = $a.replace(“l”, “+”) ) ${b} will produce He++o and you can also use velocity variables as arguments to your method calls, e.g.: #set( $a = “Hello” ) #set( $b = “+” ) #set( $c = $a.replace(“l”, … Read more
A variation that takes into account subdirectories (untested): find /var/www -type f -exec sed -i ‘s/privelages/privileges/g’ {} \; This will find all files (not directories, specified by -type f) under /var/www, and perform a sed command to replace “privelages” with “privileges” on each file it finds.
Do this so you don’t have to think about it: s = s.Replace(“‘”, @”\'”);
From UINavigationController reference: This method (popViewControllerAnimated:) removes the top view controller from the stack and makes the new top of the stack the active view controller. If the view controller at the top of the stack is the root view controller, this method does nothing. In other words, you cannot pop the last item on … Read more
A one liner cmd /e:on /v:on /c “for %f in (“* *.exe”) do (set “n=%~nxf” & set “n=!n: =_!” & ren “%~ff” “!n!” )” Spawn a cmd instance, with extensions and delayed expansion enabled, and for each exe file with spaces in name, replace spaces with underscores and rename the file with the new name
Use backreferences (i.e. brackets) to keep only the parts of the expression that you want to remember. You can recall the contents in the replacement string by using $1, $2, etc.: preg_replace(‘/(text1)text2(text3)/is’,’$1$2′,$html);
Looks like a good opportunity to use a loop: mapping = { ‘A’:’1′, ‘B’:’2′, ‘C’:’3′, ‘D’:’4′, ‘E’:’5′} for k, v in mapping.iteritems(): my_string = my_string.replace(k, v) A faster approach if you don’t mind the parentheses would be: mapping = [ (‘A’, ‘1’), (‘B’, ‘2’), (‘C’, ‘3’), (‘D’, ‘4’), (‘E’, ‘5’) ] for k, v in … Read more
