tree

Tree example

This example application reads its configuration from the KDB using code-generated functions. It then prints a tree defined inside the KDB.

Setup

CMake

# execute in the current directory or replace $PWD accordingly
mkdir "$PWD/cmake/build" && cd "$PWD/cmake/build"

cmake ..
cmake --build .

sudo kdb mount -R noresolver codegen_tree_example.conf "spec:/sw/example/tree/#0/current" specload "app=$PWD/application"
sudo kdb spec-mount "/sw/example/tree/#0/current"

Pkgconfig

# execute in the current directory or replace $PWD accordingly
cd "$PWD/pkgconfig"

make

sudo kdb mount -R noresolver codegen_tree_example.conf "spec:/sw/example/tree/#0/current" specload "app=$PWD/application"
sudo kdb spec-mount "/sw/example/tree/#0/current"

Running

To run the application, simply execute:

CMake

# execute in the current directory or replace $PWD accordingly
"$PWD/cmake/build/application"

Pkgconfig

# execute in the current directory or replace $PWD accordingly
# "$PWD/pkgconfig/application"

Configuration

The supported KDB configuration is described in spec.ini.

The root of the tree defined by root must be a reference to one of the node structs defined in tree/_. Each of these structs consists of two parts. First a string key tree/_/text that describes the text printed for this node and second an array tree/_/children/# of references to the other node structs, which are the children of the current node.
