I am trying to parse the following config.yaml file.
config.yaml
foo:
bar:
baz: [1, 2, 3, 4]
bam: "some_string_value"
test.cpp
YAML::Node configObj = YAML::LoadFile("cfig.yaml"); // loads file just fine
YAML::Node fooObj = configObj["foo"]; // this Node object is a Map
// iterate over foo node to get bar node
for( auto it = fooObj.begin(); it != fooObj.end(); ++it){
YAML::Node barMap = it->second; // this Node object is a Map
// iterate over bar node to get bad node
for( auto i = barMap.begin(); i != barMap.end(); ++i){
YAML::Node bazMap = i->second; // this node is a sequence
for( std::size_t i=0; i<bazMap.size(); i++
auto index = bazMap[i].as<int>(); // <<< This is the problem
}
}
}
The problem as far as I can see is that I am expecting index to be an int but bazMap[i].as<int>()
I am expecting to be 1 the first loop, 2 the second, etc. What I am getting instead is bazMap[i].as<int>()
is of type map. What am I missing in my understanding here?
Thanks,

Update The answer was that I stopped early in my nested for loops.
The answer that I found rests in that I was unclear on what I was getting.
In the config.yaml
file I was expecting the following:
foo.Type() == Map
bar.Type() == Sequence
baz.Type() == Sequence
but what I was getting was:
foo.Type() == Map
bar.Type() == Map
baz.Type() == Sequence
all I had to do to resolve this issue was to change the config file.
foo:
bar:
- baz: [1, 2, 3, 4]
- bam: "some_string_value"
Then it parsed exactly as I had expected.
So the issue was the format of the config file and not in the parsing logic.
