Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Changing macro input to wildcard fails if other wildcard inputs in use


If I have existing wildcard inputs in a macro that are connected to something in the macro, then I add a new input (any non-wildcard type) and try to change that input type to wildcard, the input doesn't change, even though the details panel says it is now a wildcard:

alt text


  • Disconnect the existing wildcard pin(s) then change the new input to wildcard, it changes successfully.

  • After unsuccessfully changing the type to wildcard, you can delete the input and add a new one - which will be created as a wildcard type by default (since that was the last type you used).

So easily workaroundable and also unlikely to go unnoticed so it's pretty minor, but worth reporting.

To reproduce:

  1. Make a new macro, add two inputs and one output (any non-wildcard type)

  2. Change the first input, and the output, to wildcard, and connect them together

  3. Try to change the second input to wildcard - note that it changes in the details panel but the input itself stays whatever type it was

Expected result: The input type should change to wildcard (or if it's difficult to fix, the details panel should at least display the type correctly i.e. not allow you to change it to wildcard)
