Most likely you have some system-specific include directories missing in your settings which makes it impossible for indexer to correctly parse iostream, thus the errors. Selecting Index -> Search For Unresolved Includes in the context menu of the project will give you the list of unresolved includes which you can search in /usr/include and add … Read more
Used properly, this can be a useful technique. Say you have a complex, performance critical subsystem with a fairly small public interface and a lot of non-reusable implementation code. The code runs to several thousand lines, a hundred or so private functions and quite a bit of private data. If you work with non-trivial embedded … Read more
extend – adds the specified module’s methods and constants to the target’s metaclass (i.e. the singleton class) e.g. if you call Klazz.extend(Mod), now Klazz has Mod’s methods (as class methods) if you call obj.extend(Mod), now obj has Mod’s methods (as instance methods), but no other instance of of obj.class has those methods added. extend is … Read more
I prefer the path syntax as it makes it very clear what namespace or module the header file belongs to. #include “Physics/Solver.h” Is very self-describing without requiring every module to prefix their name to header files. I almost never use the “..” syntax though, instead I have my project includes specify the correct base locations.
It’s relative to the main script, in this case A.php. Remember that include() just inserts code into the currently running script. That is, does it matter which file the include is called from No. If you want to make it matter, and do an include relative to B.php, use the __FILE__ constant (or __DIR__ since … Read more
The function could be called as if it was in the same JS File as long as the file containing the definition of the function has been loaded before the first use of the function. I.e. File1.js function alertNumber(number) { alert(number); } File2.js function alertOne() { alertNumber(“one”); } HTML <head> …. <script src=”https://stackoverflow.com/questions/3809862/File1.js” type=”text/javascript”></script> <script … Read more
Google’s cppclean (links to: download, documentation) can find several categories of C++ problems, and it can now find superfluous #includes. There’s also a Clang-based tool, include-what-you-use, that can do this. include-what-you-use can even suggest forward declarations (so you don’t have to #include so much) and optionally clean up your #includes for you. Current versions of … Read more
There is a setting: Project Settings -> Configuration Properties -> C/C++ -> Advanced -> Show Includes that will generate the tree. It maps to the compiler switch /showIncludes
This errors says your function is already defined ; which can mean : you have the same function defined in two files or you have the same function defined in two places in the same file or the file in which your function is defined is included two times (so, it seems the function is … Read more
Overview of JSP Syntax Elements First, to make things more clear, here is a short overview of JSP syntax elements: Directives: These convey information regarding the JSP page as a whole. Scripting elements: These are Java coding elements such as declarations, expressions, scriptlets, and comments. Objects and scopes: JSP objects can be created either explicitly … Read more
