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