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