Param Daemon

Param Daemon

Usage: param_daemon [-ahr] [map_filename] [ini filename]

This program read the ini file and provides parameter definitions. If the ini file is not specified, param_daemon looks in the current directory, the parent directory (../carmen.ini), and in a sibling src directory (../src/carmen.ini).

The ini file has a format defined elsewhere, but if multiple robots are defined in the ini file, then the param_daemon requires an argument to specify the robot (-r or --robot).

If the argument '-a' is given, then parameters are alphabetized when the param_daemon is queried, otherwise, the parameters are preserved in the order given in the ini file.

If a map file is specified as a command-line argument, then the param_daemon will act as a map server.

Param Edit

This program can be used to interact with the param_daemon. When parameters are modified, on/off parameters have their new values propagated to the param_daemon instantly. Numerical and string parameters are propagated when <return> is pressed. If a parameter name is underlined, its value has not been propagated to the param_daemon. Note that only some modules subscribe to changed parameter values. In some cases, modules may need to be restarted to acquire the new parameter value.

Param Tool

The param_tool allows the param_daemon to be controlled from the command line.

Usage: ./param_tool <action> <...>

<action> is one of: set, get, install, reread. Run ./param_tool help <action> to get help on using each action.

Usage: ./param_tool set <parameter name> <parameter value>

Sets a parameter value. The parameter name should be specified as a full module_variable pair.

Usage: ./param_tool get <module name | parameter name>

If a full parameter name is specified as a module_variable name, then prints out the current value of the parameter.

If a module name is specified, prints out all variables of that module.

Usage: ./param_tool install [parameter set] <parameter file>

Loads all the parameters from <parameter file>="">. If the parameter file contains multiple parameter sets, delimited using [set name], then the optional argument can be used to specify a particular set of parameters.

Usage: ./param_tool reread

Causes the param_daemon to reread the ini file, erasing all local changes.
