Before making a pull request, it is useful to make sure that compile is successful and tests are passing for each commit in the branch. We can do that automatically using -x parameter.
For example:
git rebase -i -x make

Recover as the name implies, can attempt to recover from a panic.
The recover must be attempted in a deferred statement as normal execution flow has been halted. The recover statement must appear directly within the deferred function enclosure. Recover statements in functions called by deferred f...
Most analysis customization is in the createComponents class, where the Tokenizer and TokenFilters are defined.
CharFilters can be added in the initReader method.
Analyzer analyzer = new Analyzer() {

After you’ve downloaded, these are the files and folders you should see:
The bin folder holds the Cake console executables.
The config folder holds the Configuration files CakePHP uses. Database connection details, bootstrapping, core configuration files and more should be stored here.

It is illegal to access a reference to an object that has gone out of scope or been otherwise destroyed. Such a reference is said to be dangling since it no longer refers to a valid object.
#include <iostream>
int& getX() {
int x = 42;
return x;
}
int main() {
int& r...
Pair allows us to treat two objects as one object. Pairs can be easily constructed with the help of template function std::make_pair.
Alternative way is to create pair and assign its elements (first and second) later.
#include <iostream>
#include <utility>
int main()
{
std::p...
In pass by reference of parameter passing to a method, address of actual parameter is passed to formal parameter. So actual parameter value will be changed after returning from called function.

For now I think the catalog module contains almost everything you can add to a module.
Api - Contains the service contracts. A set of interfaces that should not be changed unless the minor version changes. Not mandatory for a custom module but nice to have for comercial extensions.

Once a CMake project is initialized via project(), the output verbosity of the resulting build script can be adjusted via:
CMAKE_VERBOSE_MAKEFILE
This variable can be set via CMake's command line when configuring a project:
cmake -DCMAKE_VERBOSE_MAKEFILE=ON <PATH_TO_PROJECT_ROOT>

The axis offsets for drawing the marker that are specified by refX and refY are applied before the rotation specified by the orient parameter. Below you can see the effects of various combinations of orient and refX, refY to illustrate this.

ODS (on-disk structure) version is a number representing version of the database low-level data layout structure (ODS). When a new feature is added to Firebird it might or might not require the structure of database pages or system tables (database metadata) to change. If it does, the ODS version mu...
Copy the package installer unit file to /etc where changes will not be overwritten on an upgrade:

QModelIndex does not actually know about it's parent/child indexes, it only contains a row, a column and a pointer, and it is the models responsibility to use this data to provide information an index's relations. The model therefore needs to do a lot of conversions from the void* stored inside the ...
