问题 What is the difference between the remap, noremap, nnoremap and vnoremap mapping commands in Vim? 回答1: remap is an option that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are mapping commands , described below: :map and :noremap are recursive and non-recursive versions of the various mapping commands. What that means is that if you do: :map j gg :map Q j :noremap W j j will be mapped to gg . Q will also be mapped to gg , because j

问题 I've tried lots of methods to run my shell script but none of these works from python3 script. The command is very simple and works in terminal without problem. Here's what I've tried without sucsess: #!/usr/bin/env python3 # -*- coding: utf-8 -*- import os dat = os.popen('sh commonBash.sh').read() print(dat) if "no" in dat: print('Not found') status = 'Install' else: print('Found') status = 'Remove' When I run in terminal the output is correct and working, but when I try to run in python

问题 I have a custom Control derived class and a view model to go with. The user can do several actions with this control, and I'm thinking it's best to implement these as RoutedCommand objects or ICommand derived objects in the view model so the ControlTemplates can bind to them. Binding a command to a button in one ControlTemplate should be straightforward, but how can I bind the command to e.g. the right mouse button in another ControlTemplate? Probably a MouseGesture is involved, but I'm

问题 I am receiving the error No such file or directory in my command line and I think it's because I am not saving the ruby files somewhere specific. All I did was create a random folder where I would save my ruby files. Do I need to save my scripts in the original ruby folder? Thanks! ** This is Windows 7. More info - All I did was make a simple file named "Matz.rb" because I'm currently reading the O'reilly Ruby book. In my code all I wrote was puts "Hello Matz". I saved this on my desktop.

问题 Hello I have seen some solutions on the internet, all of them are basically creating a file, however I want to store them in an array of char. Speed is really important for me and I don't want to spend any time for working on hard drive. So popen() is not a real solution for me. 回答1: Here is a working code snippet: char bash_cmd[256] = "ls -l": char buffer[1000]; FILE *pipe; int len; pipe = popen(bash_cmd, "r"); if (NULL == pipe) { perror("pipe"); exit(1); } fgets(buffer, sizeof(buffer), pipe
