问题 What is an easy way to provide a string value to my user and let the user edit it... without him having to retype the whole string if it's not 100% correct. 回答1: Though it's difficult to tell for sure what you're asking for, you probably want Term::ReadLine. 回答2: See Term::Prompt or Prompt::ReadKey. 回答3: Or for something a bit higher level, perhaps IO::Prompt 回答4: Or if you have Perl 5.10.0 or higher, try Damian Conway's IO::Prompter (the successor to IO::Prompt). I wish I could use it for

问题 After weeks of research on this topic I've finally decided to start a thread of my own in hope there is someone out there with experience that can help. I've scoured the internet trying to understand the various coding examples out there, but I've come up short trying to put a working solution together. Let me start with some background-- Background: I have a vb.net application that is getting delivered to Windows Servers and PCs in my organization using CA IT Client Manager (ITCM). Much like

问题 I have a python script that needs to call the defined $EDITOR or $VISUAL . When the Python script is called alone, I am able to launch the $EDITOR without a hitch, but the moment I pipe something to the Python script, the $EDITOR is unable to launch. Right now, I am using nano which shows Received SIGHUP or SIGTERM every time. It appears to be the same issue described here. sinister:Programming [1313]$ echo "import os;os.system('nano')" > "sample.py" sinister:Programming [1314]$ python sample

问题 Just a short moment ago my question on how to embed an rgl in shiny was answered by Mike, but we seem to have stumbled into another issue, This is the code example: library(rgl) library(car) library(shiny) cars$time <- cars$dist/cars$speed ui <- fluidPage( hr("how do we get the plot inside this app window rather than in a popup?"), rglwidgetOutput("plot", width = 800, height = 600) ) server <- (function(input, output) { output$plot <- renderRglwidget ({ rgl.open(useNULL=F) scatter3d(x=cars

问题 I have an executable in Linux that can interact with stdin/stdout. I'm trying to write a program in C++ that can interactively call this program, send commands to its stdin, and capture it's stdout. I've been getting really confused. I don't want to fork my program (do I?). I do want my program to be able to start the "client", send data, get output, send more data, get more output, ..., and close the "client". P.S. Yes, I'm sure this has been asked before, but I've spent a few hours really

问题 How to run an interactive shell on android? (rooted device) I need the nexts steps: 1 - Execute shell process (onCreate) Process p = Runtime.getRuntime().exec(String[]{"su","-c","sh"}); 2 - Get the output (onCreate) BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream)); //dos is a field (a class attribute) dos = new DataOutputStream(p.getOutputStream()); new Thread(new Runnable() { @Override public void run() { String l; //wait the console output and write it while(

问题 EDIT: Bah, finally found a discussion on the Runtime Error, although it focuses on using PythonWin, which I did not have installed at the time. After installing PythonWin and setting up GTK (as per an earlier question), I was still encountering the error. The solution from the discussion board here was to append plt.close() after the for loop. This seems to work. However: From the command line, window is still unmovable while plotting. When exiting, PyEval_RestoreThread no longer runs into

问题 Very similar to this question: How can I start an interactive console for Perl? I just want to be able to start entering VBS statements, one at a time, and have them evaluated straight away, like Python's IDLE. 回答1: I wrote this a couple years ago. It's based on this blog post (archived here), but with a couple enhancements. Essentially it's a REPL (Read, Execute, Print, Loop) using the Execute statement: Do While True WScript.StdOut.Write(">>> ") line = Trim(WScript.StdIn.ReadLine) If LCase

问题 Typically a Shiny server would spawn separate instances for individual users, so that multiple people can individually use the same app at the same time. This answer shows how to make a simple multi-user chat room using Shiny, and this answer explains how multiple users can connect to the same session via direct IP. I got the chat example to work, two users both see the messages immediately as they're being sent, and as such can chat to one another. I'm wondering if it is at all possible to
