Apache Commons comes to the rescue (again). The Commons IO method FilenameUtils.separatorsToSystem(String path) will do what you want. Needless to say, Apache Commons IO will do a lot more besides and is worth looking at.
I use this code to keep my workstation from locking. It’s currently only set to move the mouse once every minute, you could easily adjust it though. It’s a hack, not an elegant solution. import java.awt.*; import java.util.*; public class Hal{ public static void main(String[] args) throws Exception{ Robot hal = new Robot(); Random random … Read more
Check out Code::Blocks as an option. Much lighter weight, updated constantly (via SVN nightlies), many of the same features as Eclipse. C::B has Doxyblocks, a plugin for Doxygen.
The principal problem with your code is the overuse of the double underscore namespace conflict prevention in a class that isn’t intended to be subclassed at all. In general, self.__foo is a code smell that should be accompanied by a comment along the lines of # This is a mixin and we don’t want arbitrary … Read more
The PRIuPTR macro (from <inttypes.h>) defines a decimal format for uintptr_t, which should always be large enough that you can cast a size_t to it without truncating, e.g. fprintf(stream, “Your size_t var has value %” PRIuPTR “.”, (uintptr_t) your_var);
Use if(CMAKE_CXX_COMPILER_VERSION VERSION_GREATER 4.2) as mentioned by onqtam. This obsolete answer was back from the 2.6 CMake days. You could run gcc -dumpversion and parse the output. Here is one way to do that: if (CMAKE_COMPILER_IS_GNUCC) execute_process(COMMAND ${CMAKE_C_COMPILER} -dumpversion OUTPUT_VARIABLE GCC_VERSION) string(REGEX MATCHALL “[0-9]+” GCC_VERSION_COMPONENTS ${GCC_VERSION}) list(GET GCC_VERSION_COMPONENTS 0 GCC_MAJOR) list(GET GCC_VERSION_COMPONENTS 1 GCC_MINOR) message(STATUS … Read more
It’s actually quite simple on Linux and other ELF systems: http://www.linuxjournal.com/content/embedding-file-executable-aka-hello-world-version-5967 OS X has bundles, so you just build your library as a framework and put the file in the bundle.
I don’t think it’s possible to completely hide the Windows/Unix divide with this one (unless, maybe, Boost has something). The most portable way would have to be getenv(“HOME”) on Unix and concatenating the results of getenv(“HOMEDRIVE”) and getenv(“HOMEPATH”) on Windows.
I’ve just run into the same problem. I haven’t tried it yet, but I plan to include versions of swt.jar for all platforms and load the correct one dynamically in the start of the main method. UPDATE: It worked. build.xml includes all jars: <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_linux_gtk_x86.jar”/> <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_macosx_x86.jar”/> <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_win32_x86.jar”/> <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_linux_gtk_x64.jar”/> … Read more
