I used it in a loop to skip to the next element in several places in my 5.2 project:
for filename in keys( all_filenames ) do
if file_failed_to_open[filename] then
goto nextfile
end
-- Open a file
local output_filename = get_output_filename( filename )
local file_writer = codewriter.create( output_filename )
-- failure? go to the next file
if not file_writer then
goto nextfile
end
-- Do stuff with the file here ...
::nextfile::
end
I also used it here for the same purpose, and also to repeat this loop again if necessary. When a new noun is added, it basically needs to be done again. This probably isn't the most efficient way of doing things, but hey, optimize later, right?
-- Now, go through every verb and find out if it should be included based on the nouns obtained
-- for each verb,
local potentially_used_verbs = {}
::check_all_verbs::
for index, verb in verbs.file_pairs( filename ) do
-- Go to the next if this verb's already been added, no need to check it again
if potentially_used_verbs[verb] then goto next_verb end
-- (code here to "goto next_verb" if the verb had an input parameter that wasn't in the nouns list.)
-- (code here to set the "new noun added" flag if a new noun was detected in the current verb)
if new_noun_added then
goto check_all_verbs
end
::next_verb::
end
