The `follow:` keyword of ParserYAML does not work

There is this keyword for forwarding the parsing to a given file, e.g.

#File path1/sensor_follow.yaml

type:            "CAMERA"
intrinsics:
  distortion:    [0, 0]
  follow:        "path1/filename.yaml"

#File path1/filename.yaml

pinhole_model:   [320, 240, 320, 320]

which should end up being the same as

#File sensor_self_contained.yaml

type:            "CAMERA"
intrinsics:
  distortion:    [0, 0]
  pinhole_model: [320, 240, 320, 320]

However, this does not work.

The alternative, using "@path1/filename.yaml" does not seem to be adequate as it needs a root.

Strangely, I could make it work in gtest_parser_yaml.cpp.

However, I cannot make it work in hello_wolf_autoconf.yaml!

Both codes can be checked out in MR !313 (merged), branch 248-processor-constructors-and-creators-requiring-a-sensor-pointer

I followed a little and could go as far as parser_yaml.hpp L248 : generatePath where the parameter path is exactly hello_wolf/sensor_odom_2D.yaml.

Then this happens:

Generating hello_wolf/sensor_odom_2D.yaml
libc++abi.dylib: terminating with uncaught exception of type YAML::BadFile: bad file
Abort trap: 6

Is it a matter of absolute / relative path names?

Actually, with an absolute path, it works.

OK !! I found the issue: I forgot to provide a PATH_ROOT:

ParserYAML( file , PATH_ROOT );

:-D
