459 ... for user configurable variables which are supposed to be set only

467 # keyword invocations when they are not needed. Currently no need for
468 # this was identified, thus leaving it here as a TODO. Based on
469 # comments the best approach would be to create another keyword that
470 # expects a ScalarClosure in the place of ${value} and calls the
471 # closure to get the value but only if the value is needed).
472 # The best idea how to implement this "laziness" would be to have the
473 # used to define another keyword that will be responsible for getting
474 # the default value and then passing the name of this getter keyword
475 # to this keyword. Then this keyword would call the getter (to obtain
476 # the expensive default value) only if it discovers that this value
477 # is really needed (because the variable is not set yet).
478 # TODO: Is the above TODO really necessary? Right now we don't have any
479 # examples of "expensive default values" where to obtain the default
480 # value is so expensive on resources (e.g. need to SSH somewhere to
481 # check something) that we would want to skip the calculation if the
482 # variable for which it is needed has a value already provided by the
483 # user using "pybot -v" or something. One example would be
484 # JAVA_HOME if it would be designed as user-configurable variable
485 # (currently it is not; users can specify "use jdk7" or "use jdk8"
486 # but not "use the jdk over there"; and there actually is no JAVA_HOME
487 # present in the resource, rather the Java invocation command uses the
488 # Java invocation with a full path). The default value of JAVA_HOME
489 # has to be obtained by issuing commands on the SSH connection where
490 # the resulting Java invocation command will be used (to check
491 # multiple candidate paths until one that fits is found) and we could
492 # skip all this checking if a JAVA_HOME was supplied by the user using
