How do I use snippets in a 'Save As' Dialog?

[Empyreal]

I've got a snippet defined as:

"ds," = "{date:yyyy-MM-dd' '}"

I like to prepend dates to filenames and so when I'm in the SaveAs dialog of the Atom Editor, for instance, and I type my trigger, I just get a low-freq buzz (indicating snippet failure, I'm guessing).  

 

The snippets work as designed in the actual text of a file.  

 

Has anyone else run into this, or more to the point, does someone have a solution?  TIA!

@Empyreal I wonder if this is an Atom (electron) save dialog issue as it seems to work fine in the macOS native save dialog. Does it work fine for you in the TextEdit Save dialog?

*** Bingo.  It works fine in Text Edit, and doesn't work at all on Atom.  

 

It must be an electron thing.

 

Thanks for responding. I wonder if there is a workaround for electron apps?
