path

问题 I have a project I can build on both Linux and Windows using CMake. The only issue is that Unix-style paths, in CMakeLists.txt, can't work on Windows (which uses backslashes instead of slashes, also requiring the drive letter). Is there any way I can write a cross-platform CMakeLists.txt? 回答1: You question affects different details: Just don't use backslashes. Windows will also process slashes. Don't use drive letters. Use relative paths everywhere. GET_FILENAME_COMPONENT(X "${CMAKE_CURRENT

问题 I'm looking for a Delphi function which returns the file URL path from the Windows path. Is there something for it built-in in Delphi ? Example: Input C:\Users\Documents\File.txt Output file:///C:/Users/Documents/File.txt Thanks 回答1: You can use the UrlCreateFromPath API function. Here is the example: uses ComObj, WinInet, ShLwApi; function FilePathToURL(const FilePath: string): string; var BufferLen: DWORD; begin BufferLen := INTERNET_MAX_URL_LENGTH; SetLength(Result, BufferLen); OleCheck

问题 I was wondering, what is the longest possible name length allowed by the Windows kernel? E.g.: I know the kernel uses UNICODE_STRING structures to hold all object paths, and since the byte length of a wide-character string is stored inside a USHORT , that allows for a maximum path length of 2^15 - 1 characters. Is there a similar, hard restriction on a file name (rather than path)? (I don't care if NTFS or FAT32 imposes a particular restriction; I'm looking for the longest possible

问题 Is there a way to set relative path to the icon in win shortcut? for the target location it works fine: %windir%\system32\cmd.exe /c "cd %CD% && start fileToExecute.bat" I read that win shortcuts can pick up icon from .exe files automatically but what to do if my target file is a batch file? 回答1: It's not entirely clear what you're asking, since your title says one thing but your question says another. if the question is whether it is possible to set a relative path for the icon location in a

问题 I am using Python on Mac OSX Leopard. I am trying to run the program 'dot' (part of Graphviz) from Python: # -*- coding: utf-8 -*- import os print os.environ['PATH'] print os.system("ls >> a.txt") print os.system("dot -o9.png -Tpng ./6.dot") The command "ls" is there just to make sure that python is in the correct directory. It is. The result that I get is: /usr/bin:/bin:/usr/sbin:/sbin 0 32512 My understanding is that 32512 error means that python could not find the file, and since the file

问题 This is my Python program: #!/usr/bin/env python import os BASE_PATH = os.path.dirname(__file__) print BASE_PATH If I run this using python myfile.py it prints an empty string. If I run it using myfile.py , it prints the correct path. Why is this? I'm using Windows Vista and Python 2.6.2. 回答1: It's just a harmless windows quirk; you can compensate by using os.path.abspath(__file__) , see the docs 回答2: os.path.normpath(os.path.join(os.getcwd(),os.path.dirname(__file__))) 回答3: In many cases it

问题 When running Ruby code on NetBeans (like when running the tests) I'm having some failures because a program is not being found. That program is installed somewhere in /opt and while for the shell I get that added to my PATH, it seems NetBeans is not getting it. How do I specify the PATH in NetBeans? 回答1: In Unix, in your netbeans install directory (we'll call it $NETBEANS), there's an etc directory. $NETBEANS/etc/netbeans.conf can be changed to add things to your PATH or set other environment

问题 What's the most concise (but safe) way to remove a drive name, network path, etc. from an absolute path in C#? For example, converting \\networkmachine\foo\bar or C:\foo\bar to \foo\bar . There seem to be a good number of questions already answered with regards to path matters, but I couldn't quite find what I was looking for. My own first thought that came to mind was to use Path.GetFullPath() to ensure I'm indeed working with an absolute path and then to just use a regular expression to

问题 I'm running the following applescript: tell application "Finder" set input to POSIX file "/Users/sam/Desktop/Resized" set theFiles to (every file of folder input whose name does not contain "- Resized") end tell return theFiles It's working as it should, though it's returning: {document file "HighResCat.jpg" of folder "Resized" of folder "Desktop" of folder "sam" of folder "Users" of startup disk of application "Finder", document file "madonna.jpg" of folder "Resized" of folder "Desktop" of
