问题 We have a very complex SVN tree at my employer that has several project trees contained within the same repository, as follows (each leaf in this diagram has a complete trunk/branches/tags structure in it, btw) svn.contoso.com/root_repository_path/ |- project1 |- project2 | |- subprojectA | |- subprojectB |- project3 |- project4 |- |- subprojectA |- |- subprojectB |- project5 (the project I'm on) This works fine so far. However, a fellow developer did a bit of reorganizing, and moved project5

问题 Let's say we have a web directory with the following paths: framework/ index.php ... instance/ index.php -> ../framework/index.php (symlink) ... If we now make a request for (...)/instance/index.php PHP will resolve the symlinks and set __FILE__ as (...)/framework/index.php Is there a way around this so e.g. dirname(__FILE__) would be (...)/instance ? EDIT: Since it has been pointed out, I'm actually not sure if PHP itself is resolving the links or something else. In my case I'm using nginx

问题 Is it possible to get the path to files stored inside Core Data, or can I only extract the file itself? I need the path to files stored as NSData attribute in Core Data, not the database itself. Some iOS features often ask for an NSURL rather than the file itself, and I have yet to figure out how to combine this with Core Data. 回答1: There are no "files" inside of the database if you are using SQLite. The database is a single file. If you are storing binary data in your database then there is

问题 For one possible solution, see my second post below. Having a PHP array storing data from a tree structure, with the first column storing the id of the node, the second column storing the path of the parent node as a concatenation of id values, the third columns storing the name of the node, which is the best way to generate a text path (breadcrumbs) from the path done of ids? Example records: id | path | name --------------------- 1 | 0 | edible 14 | 1 | fruits 53 | 1.14 | apples 54 | 1.14 |

问题 So I have a make file which uses arm-eabi-none-xxx commands, but when I run make I get a "Command not Found" error: bash-4.2$ make arm-none-eabi-as -I source/ source/mailbox.s -o build/mailbox.o make: arm-none-eabi-as: Command not found make: *** [build/mailbox.o] Error 127 Weird bit, is the command exists and is in my path (the following is in the same directory as the makefile): bash-4.2$ arm-none-eabi-as --version GNU assembler (Sourcery G++ Lite 2008q3-66) 2.18.50.20080215 This assembler

问题 Working with this code What is the most elegant way to remove a path from the $PATH variable in Bash? export PATH=`echo ${PATH} | awk -v RS=: -v ORS=: '/SDE/ {next} {print}'` | sed 's/:*$//' In this instance if I run just the: export PATH=`echo ${PATH} | awk -v RS=: -v ORS=: '/SDE/ {next} {print}'` I can get the path containing /SDE/ removed; however a : remains. The sed command after I am assuming should remove that. When I run this entire command at once nothing gets removed at all. What is

问题 I recently installed RVM. After loading my .rvmrc I tried bundle install and got the error informing me bundler was not installed. After installing bundler , the bundler not installed error persisted. After some quick digging I discovered that the RVM gem paths are not being used by rubygems. Here is gem env : RubyGems Environment: - RUBYGEMS VERSION: 1.8.24 - RUBY VERSION: 1.9.2 (2011-07-09 patchlevel 290) [x86_64-linux] - INSTALLATION DIRECTORY: /home/jhalecom/ruby/gems - RUBY EXECUTABLE:

问题 Assume that I have a folder with some folders and pages on it: FolderA PageA1.php FolderB FolderB1 PageB11.php FolderB2 PageB21.php PageB1.php FolderC PageC1.php On PageB11 , I have: require_once 'FolderB2/PageB21.php'; While calling PageB11 on PageB1 : require_once 'FolderB1/PageB11.php'; It's work fine. But now the problem is, while on PageB11 also have a function that call the page itself ( PageB11 ), then the error showed: Warning: require_once(FolderB2/PageB21.php): failed to open stream
