Is there a command which will print the path of the file in the repo-browser in the command line? SVN diff only prints the file name. Thank you. svn info path/to/filename will show you several pieces of information. The ones you're looking for are URL and Repository Root: $ svn info mydialog.h [...] URL: http://svn.server.net/my-repo/trunk/ui/mydialog.h Repository Root: http://svn.server.net/my-repo [...] URL is the absolute position of the file, and Repository Root is the base URL of the repository. URL will always start with the address of Repository Root, so if you trim Repository Root from

After I make a jump to anywhere in the world, whether in the current file or a different file, is it possible to make vim automatically run zz (re-center on current line)? I want this after things like search, ctrl-o and ctrl-i ... and pretty much any movement other than hjkl . Thanks. Voila: " Center screen on next/previous selection. nnoremap n nzz nnoremap N Nzz " Last and next jump should center too. nnoremap <C-o> <C-o>zz nnoremap <C-i> <C-i>zz 来源： https://stackoverflow.com/questions/2372584/auto-zz-in-vim-after-a-jump

How would one replace all instances of 'foo' with 'bar' and 'bar' with 'foo' in vim? Aside from using a temporary word for the change, you could also use abolish plugin like this: :%SubVert/{foo,bar}/{bar,foo}/g kev Take a look at this: how to write only one pattern to exchange two strings in two-ways in vim :s/foo\|bar/\={'foo':'bar','bar':'foo'}[submatch(0)]/g :%s/foo/bbaarr/g :%s/bar/foo/g :%s/bbaarr/foo/g It must exist an smartest way to do it, but this one will work for sure ! You can do it using temp word. Just be sure that it doesn't exists in the current document. /\<asd123\> :%s/\<foo

I am trying to change the java.io.tmpdir directory using this command java -Djava.io.tmpdir=/temporary But this doesnot succeed and displays the 'Usage' of the java command. I am doing this in a RHEL machine. Thanks in advance I have deployed an application on WebLogiv which uses axis2 version 1.5. I find that axis2 1.5 using java.io.tmpdir to store its temp files.

I have a static class which contains a RoutedUICommand that I would like to use in binding. public static class CommandLibrary { public static ProjectViewModel Project { get; set; } public static RoutedUICommand AddPage { get; private set; } static CommandLibrary() { AddPage = new RoutedUICommand("AddPage", "AddPage", typeof(CommandLibrary)); } public static void AddPage_Executed(object sender, ExecutedRoutedEventArgs args) { Project.AddPage(); } public static void AddPage_CanExecute(object sender, CanExecuteRoutedEventArgs args) { // We need a project before we can add pages. if (Project !=

How would you run a command and pass some custom arguments with Flutter/Dart so they can then be accessed in the main() call such as: flutter run -device [my custom arg] So then I can access it with: void main(List<String> args) { print(args.toString()); } Thank you. There is no way to do that, because when you start an app on your device there are also no parameters that are passed. If this is for development, you can pass -t lib/my_alternate_main.dart to flutter run to easily switch between different settings where each alternate entry-point file calls the same application code with

In vim, when I hit :wq it is almost always an accident that occurred when attempting to input :w . I would like to disable :wq . The closest I found is cmap , but it has some odd behavior. If I do something like :cmap wq w I can no longer even input :wq ; it just remaps the keystroke sequence wq to w in command mode.

EDIT: clarified why :cmap is not an option for me A better solution can be: :cabbrev wq w But I'm not
