400 [Arguments] ${name} ${value}
401 [Documentation] Set a default value for an user configurable variable.
402 ... This keyword is needed if your default value is calculated using
403 ... a complex expression which needs BuiltIn.Evaluate or even more
404 ... complex keywords. It sets the variable ${name} (the name of the
405 ... variable MUST be specified WITHOUT the ${} syntactic sugar due
406 ... to limitations of Robot Framework) to ${value} but only if the
407 ... variable ${name} was not set previously. This keyword is intended
408 ... for user configurable variables which are supposed to be set only
409 ... with pybot -v; calling this keyword on a variable that was already
410 ... set by another keyword will silently turn the call into a NOP and
411 ... thus is a bug in the suite or resource trying to call this
413 # TODO: Figure out how to make the ${value} evaluation "lazy" (meaning
414 # evaluating it only when the user did not set anything and thus the
415 # default is needed). This might be needed to avoid potentially costly
416 # keyword invocations when they are not needed. Currently no need for
417 # this was identified, thus leaving it here as a TODO. Based on
418 # comments the best approach would be to create another keyword that
419 # expects a ScalarClosure in the place of ${value} and calls the
420 # closure to get the value but only if the value is needed).
421 # The best idea how to implement this "laziness" would be to have the
422 # used to define another keyword that will be responsible for getting
423 # the default value and then passing the name of this getter keyword
424 # to this keyword. Then this keyword would call the getter (to obtain
425 # the expensive default value) only if it discovers that this value
426 # is really needed (because the variable is not set yet).
427 # TODO: Is the above TODO really necessary? Right now we don't have any
428 # examples of "expensive default values" where to obtain the default
429 # value is so expensive on resources (e.g. need to SSH somewhere to
430 # check something) that we would want to skip the calculation if the
431 # variable for which it is needed has a value already provided by the
432 # user using "pybot -v" or something. One example would be
433 # JAVA_HOME if it would be designed as user-configurable variable
434 # (currently it is not; users can specify "use jdk7" or "use jdk8"
435 # but not "use the jdk over there"; and there actually is no JAVA_HOME
436 # present in the resource, rather the Java invocation command uses the
437 # Java invocation with a full path). The default value of JAVA_HOME
438 # has to be obtained by issuing commands on the SSH connection where
439 # the resulting Java invocation command will be used (to check
440 # multiple candidate paths until one that fits is found) and we could
441 # skip all this checking if a JAVA_HOME was supplied by the user using
