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