问题 Is it possible to take a static library written in C++ and somehow integrate it into a .NET process in a way that the .NET process will be integrated with the lib into one exe file? What I mean is that I know I can invoke a c++ DLL from within a C# process but the user will still have to have the C++ DLL, but is it possible to use a lib instead of a DLL?(this way the user won't even know that the exe uses my library). and if it is possible, how? 回答1: Unique among other managed languages, C++

问题 Creating custom commands in flask needs access to the app, which is generally created in app.py like this: import click from flask import Flask app = Flask(__name__) @app.cli.command("create-user") @click.argument("name") def create_user(name): ... However, in order not to bloat my app.py, I want to put my custom commands in a separate file e.g. commands.py , but this doesn't work because the entrypoint to my project is app.py , so I'll have to import app in commands.py and import my commands

问题 How can I echo a line into multiple files in a single command? Example: echo Hello World! into file1.log and file2.log EDIT: Windows-XP Batch Script CHALLENGE: Give me a one-liner =D. If it can't be done w/one line I'm not interested. My solution was ECHO Hello World!>tmp.log & COPY file1.log + tmp.log & COPY file2.log + tmp.log But I'm hoping for one that is a single command and not multiple commands. 回答1: If you need it only for single lines (of input) you can write your own tee with batch.

问题 AFAIK, it should be possible. I know that convert of ImageMagick makes this task trivial, but I cannot use ImageMagick, therefore I am leaning towards Gimp (on Windows). I have tried with this Guile script: (define (resize-image filename new-filename scale) (let* ((image (car (gimp-file-load RUN-NONINTERACTIVE filename filename))) (drawable (car (gimp-image-get-active-layer image))) (width (gimp-image-width image)) (height (gimp-image-height image))) (gimp-image-scale-full image (* width

问题 I am making a command line interface in Python 3.1.1 using the cmd module. Is there a way to create a command with more than one name e.g. "quit" and "exit"? Or would it just be a case of making a number of commands that all reference the same function? 回答1: Yes, it would just be a case of making a number of commands that all reference the same function. This is common. It often helps to provide multiple common aliases for a command. It makes the user's life simpler because the odds of them

问题 I've got a Phonegap/Cordova 3.0 app that I am testing on Android. Since version 2.x, Cordova relies heavily on the command-line terminal. I've done all the setup stuff and I can build the app. But two things are troubling me. First of all, an Android project has two www folders. One is [myproject]/www. The other is [myproject]/platforms/android/assets/www. I'm not sure which of these folders to edit when I am fixing bugs. If I am correct, the first one is where you place your app files before

问题 In a spark shell or application (written in Scala/maven build), I am unable to use the static builder method from the Apache Commons CLI package. I have confirmed that I am including the jar in the class path and have access to the Option class along with other classes in the package like Options , DefaultParser , etc. Why can I not use this public static method in Scala? import org.apache.commons.cli.Option val opt = Option.builder("foo").build() error: value builder is not a member of
