[Rock-dev] configuration of dynamic properties

Thu Jul 25 18:00:49 CEST 2013

Problem solved.

A coma AND a space are required to clearly separate the different values 
of a vector in a config .yml file. i.e: 

in .orogen:
property "property_name", "std::vector<int>"

in .yml:
property_name: [1,2,3,4]  -> does not work
property_name: [1, 2, 3, 4] -> this works

Vector can be of any type (numeric, string, boolean)

Hello, 

Yes I tried removing the quotes and then it accepts the whole vector as a 
single item, I mean the vector is size 1. And the same happens with the 
other two fields of the can_parameters structure (CanId and Type), where I 
put a lists of integer numbers and it treats them like a single number. 
The only case it works is when I put only one parameter per field (as if I 
had one single motor). But at the moment I put more than one item in the 
vectors the data does not make sense anymore. 

The config vector for CanId [1,10,11] will be understood as a single value 
[11011], and the same with Type and Name. In the case of Name it even 
takes the coma. The config vector for Name: 
[WHEEL_DRIVE_FL,WHEEL_DRIVE_FR,WHEEL_DRIVE_CL] is interpreted as 
"WHEEL_DRIVE_FL,WHEEL_DRIVE_FR,WHEEL_DRIVE_CL" 

Any ideas why these is happening?

Hello Martin,

Did you try to remove the quotes?
I have this in the orogen:

# A configuration property (here, a std::string). Its value can be 
retrieved
   # in the C++ code with # _config_value.get() and 
_config_value.set(new_value).
   property "config_value", "/std/string", "Hola"
   property "config_vector", "std::vector<std::string>"

And then the yml file is:

--- name:default
# A configuration property (here, a std::string). Its value can be 
retrieved
# in the C++ code with # _config_value.get() and 
_config_value.set(new_value).
config_value: Hola
# no documentation available for this property
config_vector: [Hola, Adios, Buenas]

It worked for me. Have a look to the attached screenshot.

Regards,

Javier.

Dear all, 

I have a property in a component of the following defined structure: 

struct CanParams 
{ 
       std::vector<int> CanId; 
       std::vector<std::string> Name; 
       std::vector<MotorType> Type; 
} 

with 

enum MotorType 
{ 
       WHEEL_DRIVE, 
       WHEEL_STEER, 
       WHEEL_WALK, 
       etc. 
} 

In the .yml configuration file I set the values for CanParams structure as 
follows: 

--- name:default 
can_parameters: 
       CanId: [1,10,11,12, etc. ] 
       Name: ["WHEEL_DRIVE_FL","WHEEL_DRIVE_FR","WHEEL_DRIVE_CL", etc. ] 
       Type: [WHEEL_DRIVE,WHEEL_DRIVE,WHEEL_DRIVE, etc. ] 
num_nodes: 19 
etc. 

When applying this conf file it shows an error loading the .yml file, 
precisely when loading the Name field. I don't know if the nomenclature I 
am using is the right one, I have tried with single quotes, semicolon, etc 
but nome seems to work. Attached an screenshot of the error.
