interactive

问题 Just wondering, is it possible to create an interactive shell, using PHP alone. I mean something like you have with databases, python, etc. If it is, how? 回答1: Yes, it's possible. In order to be interactive, the program must be able to wait for and read in user input from stdin . In PHP, you can read from stdin by opening a file descriptor to 'php://stdin'. Taken from an answer to different question, here's an example of an interactive user prompt in PHP (when run from the command line, of

问题 This might be a silly question, but as I can\'t find an answer, I have to ask it. In interactive python I want to process a message which i get with: >>> message = sys.stdin.readlines() Everything works fine, but... how to stop it from getting an input and make it save into message variable? Stopping with ctrl+c stops whole process so there is no input to be saved anywhere. I guess there\'s an easy answer I just can\'t find... 回答1: For unix based system : Hello, you can tape : Ctrl d Ctrl d

问题 Is there any way to start a interactive shell in a container using Docker Compose only? I\'ve tried something like this, in my docker-compose.yml: myapp: image: alpine:latest entrypoint: /bin/sh When I start this container using docker-compose up it\'s exited immediately. Are there any flags I can add to the entrypoint command, or as and additional option to myapp, to start as interactive shell? I know there are native docker command options to achieve this, just curious if it\'s possible

问题 In a Python script, is there any way to tell if the interpreter is in interactive mode? This would be useful so that, for instance, when you run an interactive Python session and import a module, slightly different code is executed (for example, logging is turned off). I\'ve looked at tell whether python is in -i mode and tried the code there, however, that function only returns true if Python has been invoked with the -i flag and not when the command used to invoke interactive mode is python

问题 Is there a way to programmatically force a Python script to drop into a REPL at an arbitrary point in its execution, even if the script was launched from the command line? I\'m writing a quick and dirty plotting program, which I want to read data from stdin or a file, plot it, and then drop into the REPL to allow for the plot to be customized. 回答1: You could try using the interactive option for python: python -i program.py This will execute the code in program.py, then go to the REPL.

问题 I\'m trying to use git add --interactive to selectively add some changes to my index, but I continually receive the \"Your edited hunk does not apply. Edit again...\" message. I get this message even if I choose the e option, and immediately save/close my editor. In other words, without editing the hunk at all, the patch doesn\'t apply. Here\'s the exact example I\'m using (I\'m trying to put together a small demo): Original file: first change second change off branch third change off branch

问题 I used matplotlib to create some plot, which depends on 8 variables. I would like to study how the plot changes when I change some of them. I created some script that calls the matplotlib one and generates different snapshots that later I convert into a movie, it is not bad, but a bit clumsy. I wonder if somehow I could interact with the plot regeneration using keyboard keys to increase / decrease values of some of the variables and see instantly how the plot changes. What is the best

问题 I have a script that I want to run from within python (2.6.5) that follows the logic below: Prompt user for password. Looks like (\"Enter password: \") (*Note: Input does not echo to screen) Output irrelevant information Prompt user for response (\"Blah Blah filename.txt blah blah (Y/N)?: \") The last prompt line contains text which I need to parse (filename.txt). The response provided doesn\'t matter (The program could actually exit here without providing one, as long as I can parse the line

问题 Suppose I\'m using R\'s interactive console, and I\'ve just done something like this: long_running_command() That long-running command returns a value, and I\'ve just realized that I wanted to assign that value to a variable instead of discard it. So how can I get that value without running the command again? Is there a command like this? result = get_last_return_value() 回答1: .Last.value is an answer. It was answered once but you have better title. 来源： https://stackoverflow.com/questions

问题 Scenario: An interactive CLI Python program, that is in need for a password. That means also, there\'s no GUI solution possible. In bash I could get a password read in without re-prompting it on screen via read -s Is there something similar for Python? I.e., password = raw_input(\'Password: \', dont_print_statement_back_to_screen) Alternative: Replace the typed characters with \'*\' before sending them back to screen (aka browser\' style). 回答1: >>> import getpass >>> pw = getpass.getpass()
