It often happens that I will be using a piece of software, and I will have the opportunity to specify something to the effect of 'qualifying extensions', and extensions that meet that criteria will be applied to that setting.
User can upload files. Allowed file types (separate by comma):[text field here].
I think that example is perfect, because it is just the sort of place where the ambiguity gets introduced.
What is the acceptable format here:
*.gif,*.jpg,*.pdf,*.svg,...(I grant that for the example above, it's probably obvious not to put it this way)
A lot of times, putting in the wrong format won't cause an error, but, the filter won't work, and you may not notice until your down the road a bit. Not wanting to deal with that future, (given the example above) I put in both -
.svg,svg,gif,.gif,pdf,.pdf,jpg,.jpg - which seems stupid.
I have seen each of the specified formats be the one that the software requires, and no matter what format the program wants, it almost never makes it explicit.
My questions are as follows:
Am I crazy for thinking this is an issue? / Does anyone else share my experience here?
Given with the example above (perhaps applying more universally as well), what is the best way to remove the ambiguity?
