C++ interpreter / console / snippet compiler

阅读更多关于 C++ interpreter / console / snippet compiler

I am looking for a program where I can enter a C++ code snippet in one window, press a button, and get output in another window. Compilation should somehow be hidden behind the button. On a per-snippet basis would be fine, full interactive probably asking too much. It should run under Linux/Unix. Main use case would be learning/testing/short debugging, etc. Related stuff I found: -- the Reinteract project for python (which i'm told sage has features similar to) -- the same thread for C# here: C# Console? -- the CINT interpreter from the CERN ROOT project (which may be close, but maybe there

How can I check to see if a Python script was started interactively?

阅读更多关于 How can I check to see if a Python script was started interactively?

问题 I'd like for a script of mine to have 2 behaviours, one when started as a scheduled task, and another if started manually. How could I test for interactiveness? EDIT: this could either be a cron job, or started by a windows batch file, through the scheduled tasks. 回答1: You should simply add a command-line switch in the scheduled task, and check for it in your script, modifying the behavior as appropriate. Explicit is better than implicit. One benefit to this design: you'll be able to test

问题 How does one code an interactive response in this while loop? #!/bin/bash shows=$(< ${HOME}/.get_iplayer/tv.cache) # ... # ... stuff with shows omitted ... # ... function print_show { # ... return } while read -r line do print_show "$line" read -n 1 -p "do stuff?

The app will (from what Ive

How to do interactive SMS in .NET?

阅读更多关于 How to do interactive SMS in .NET?

问题 I want to write an app that sends an SMS to users, and when the recipients texts back, I receive that response, including the originating phone number, and my program can react to that response. I've googled "Interactive SMS" but didn't find anything that was clearly a fit. Has anyone else done this, got any recommendations for a paid service that provides this kind of functionality? Alternatively, do you have any other recommendations for how to build this service into my app, which will

问题 I need to automate a interactive rebase or replace it by other commands. Just let me explain my current situation: In an svn->git transition i need to rebase the newly created git repository to fix a "history cut-offs" made during SVN. Here is my manual workflow to fix the problem. branchNEW: containing history from SOMEDAY until now branchOLD: containing history from past to SOMEDAY EDIT or as ascii: branchNEW: Y - Z branchOLD: W - X Both branches have no common commits.

Detecting when a python script is being run interactively in ipython

阅读更多关于 Detecting when a python script is being run interactively in ipython

问题 Is there a way for a python script to automatically detect whether it is being run interactively or not? Alternatively, can one detect whether ipython is being used versus the regular c python executable? Background: My python scripts generally have a call to exit() in them. From time to time, I run the scripts interactively for debugging and profiling, usually in ipython. When I'm running interactively, I want to suppress the calls to exit. Clarification : Suppose I have a script, myscript

git rebase interactive: squash merge commits together

阅读更多关于 git rebase interactive: squash merge commits together

I wanted to have a simple solution to squash two merge commits together during an interactive rebase. My repository looks like: X --- Y --------- M1 -------- M2 (my-feature) / / / / / / a --- b --- c --- d --- e --- f (stable) That is, I have a my-feature branch that has been merged twice recently, with no real commits in between. I don't just want to rebase the my-feature branch since it is a published branch of its own, I just want to squash together the last two merge commits into one (haven't published those commits yet) X --- Y ---- M (my-feature) / / / / a --- ... -- f (stable) I tried:

How can I start an interactive console for Perl?

阅读更多关于 How can I start an interactive console for Perl?

How can I start an interactive console for Perl, similar to the irb command for Ruby or python for Python? You can use the perl debugger on a trivial program, like so: perl -de1 Alternatively there's Alexis Sukrieh 's Perl Console application, but I haven't used it. Not only did Matt Trout write an article about a REPL, he actually wrote one - Devel::REPL I've used it a bit and it works fairly well, and it's under active development. BTW, I have no idea why someone modded down the person who mentioned using "perl -e" from the console. This isn't really a REPL, true, but it's fantastically
