How to check if directory 1 is a subdirectory of dir2 and vice versa

阅读更多关于 How to check if directory 1 is a subdirectory of dir2 and vice versa

问题 What is an easy way to check if directory 1 is a subdirectory of directory 2 and vice versa? I checked the Path and DirectoryInfo helperclasses but found no system-ready function for this. I thought it would be in there somewhere. Do you guys have an idea where to find this? I tried writing a check myself, but it's more complicated than I had anticipated when I started. 回答1: You can compare directory2 to directory1's Parent property when using a DirectoryInfo in both cases. DirectoryInfo d1 =

Extract a specific file from a zip archive without maintaining directory structure in python

阅读更多关于 Extract a specific file from a zip archive without maintaining directory structure in python

问题 I'm trying to extract a specific file from a zip archive using python. In this case, extract an apk's icon from the apk itself. I am currently using with zipfile.ZipFile('/path/to/my_file.apk') as z: # extract /res/drawable/icon.png from apk to /temp/... z.extract('/res/drawable/icon.png', 'temp/') which does work, in my script directory it's creating temp/res/drawable/icon.png which is temp plus the same path as the file is inside the apk. What I actually want is to end up with temp/icon.png

问题 Say you want want to create a programming project that mixes C++ and Python . The Foo C++ project structure uses CMake , and a Python module is created by using Swig . The tree structure would look something like this: ├── CMakeLists.txt ├── FooConfig.cmake.in ├── FooConfigVersion.cmake.in ├── Makefile ├── README ├── foo │ ├── CMakeLists.txt │ ├── config.hpp.in │ ├── foo.cpp │ └── foo.hpp └── swig └── foo.i Now you would like to make use of the Foo project within a Python project, say Bar : ├

Streaming recursive descent of a directory in Haskell

阅读更多关于 Streaming recursive descent of a directory in Haskell

问题 I am trying to do a recursive descent of a directory structure using Haskell. I would like to only retrieve the child directories and files as needed (lazily). I wrote the following code, but when I run it, the trace shows that all directories are visited before the first file: module Main where import Control.Monad ( forM, forM_, liftM ) import Debug.Trace ( trace ) import System.Directory ( doesDirectoryExist, getDirectoryContents ) import System.Environment ( getArgs ) import System

Directory structure for a C++ library

阅读更多关于 Directory structure for a C++ library

I am working on a C++ library. Ultimately, I would like to make it publicly available for multiple platforms (Linux and Windows at least), along with some examples and Python bindings. Work is progressing nicely, but at the moment the project is quite messy, built solely in and for Visual C++ and not multi-platform at all. Therefore, I feel a cleanup is in order. The first thing I'd like to improve is the project's directory structure. I'd like to create a structure that is suitable for the Automake tools to allow easy compilation on multiple platforms, but I've never used these before. Since

SVN: Checkout/export only the directory structure

阅读更多关于 SVN: Checkout/export only the directory structure

Is there a way to perform a SVN checkout (or export), which would fetch only the directory structure ; that is to say, no files? Dave Stenglein svn ls -R {svnrepo} | grep "/$" | xargs -n 1 mkdir -p Export, not a checkout. [Updated] With checkout: env REPO={repo} sh -c 'svn ls -R $REPO | grep "/\$" | xargs -n 1 svn co --depth=empty $REPO' This will be pretty slow for anything too large. You can specify --non-recursive to the checkout command, might help you to get what you want. jor There is a python script in the contrib tools of subversion , which creates the directory structure with empty

Folder structure of a PHP MVC framework… am I doing this right?

阅读更多关于 Folder structure of a PHP MVC framework… am I doing this right?

I'm currently working on my own PHP Framework, and I need some help figuring out if I'm going in the right direction or not... The framework is both for my own use and to generally advance my PHP skills further. I've encountered numerous problems that by overcoming them I have learned a great deal, and love being able to create something from nothing, so I'd rather not see answers like "Just use Zend"! ;) I have read a bunch of articles both on Stack Overflow and a bunch of other sites, but can't quite get the right answer I need, so hopefully someone can give me some helpful advice! I've

Official way of adding custom fonts to Rails 4?

阅读更多关于 Official way of adding custom fonts to Rails 4?

I'm researching how to add custom fonts to my Rails app, e.g. by adding a fonts folder in the assets folder - and I cannot find an "official" Rails way on how to do this. Yes, there are plenty of questions/answers here on SO about the matter, all seemingly with their own hacks. But shouldn't such a common practice go under Rails' famous "convention over configuration"? Or if I've missed it - where is the documentation reference on how to organize fonts in a Rails app? Nikhil Nanjappa Yes the link given will explain it well, however if u need another detailed explanation then here it is Firstly

Thousands of images, how should I organize the directory structure? (linux)

阅读更多关于 Thousands of images, how should I organize the directory structure? (linux)

I am getting thousands of pictures uploaded by thousands of users on my Linux server, which is hosted by 1and1.com (I believe they use CentOS, but am unsure of the version). This is a language agnostic question, however, for your reference, I am using PHP. My first thought was to just dump them all in the same directory, however, I remember a little while ago, there was a limit to how many files or directories could be dropped in a directory. My second thought was to partition the files inside directories based on the users email address (as it is what I am using for the user name anyhow) but

Storage Access Framework - failing to obtain document tree from uri (returned from Drive app)

阅读更多关于 Storage Access Framework - failing to obtain document tree from uri (returned from Drive app)

My Android app wants to create a folder in Google Drive and get the uri from the Drive app on the device. It sends an intent, you can see the code below: private void createFolder(String folderName) { Intent intent = new Intent(Intent.ACTION_CREATE_DOCUMENT); intent.addCategory(Intent.CATEGORY_OPENABLE); // Create a file with the requested MIME type. intent.setType("vnd.android.document/directory"); intent.putExtra(Intent.EXTRA_TITLE, folderName); startActivityForResult(intent, WRITE_REQUEST_CODE); } then it gets the returned data, you can see the code below: @Override protected void
