535 # TODO: Figure out how to make the ${value} evaluation "lazy" (meaning
536 # evaluating it only when the user did not set anything and thus the
537 # default is needed). This might be needed to avoid potentially costly
538 # keyword invocations when they are not needed. Currently no need for
539 # this was identified, thus leaving it here as a TODO. Based on
540 # comments the best approach would be to create another keyword that
541 # expects a ScalarClosure in the place of ${value} and calls the
542 # closure to get the value but only if the value is needed).
543 # The best idea how to implement this "laziness" would be to have the
544 # used to define another keyword that will be responsible for getting
545 # the default value and then passing the name of this getter keyword
546 # to this keyword. Then this keyword would call the getter (to obtain
547 # the expensive default value) only if it discovers that this value
548 # is really needed (because the variable is not set yet).
549 # TODO: Is the above TODO really necessary? Right now we don't have any
550 # examples of "expensive default values" where to obtain the default
551 # value is so expensive on resources (e.g. need to SSH somewhere to
552 # check something) that we would want to skip the calculation if the
553 # variable for which it is needed has a value already provided by the
554 # user using "pybot -v" or something. One example would be
555 # JAVA_HOME if it would be designed as user-configurable variable
556 # (currently it is not; users can specify "use jdk7" or "use jdk8"
557 # but not "use the jdk over there"; and there actually is no JAVA_HOME
558 # present in the resource, rather the Java invocation command uses the
559 # Java invocation with a full path). The default value of JAVA_HOME
560 # has to be obtained by issuing commands on the SSH connection where
561 # the resulting Java invocation command will be used (to check
562 # multiple candidate paths until one that fits is found) and we could
563 # skip all this checking if a JAVA_HOME was supplied by the user using
