I’d look at the current function definition to be sure (C-h f citar—library-file-action), but open is the standard macOS command for opening files. The Linux equivalent is xdg-open. My guess is that somehow you’ve told citar or org or emacs to use open for these links. Or it’s possible that the citar devs accidentally hard coded open into the function.

Hi,

After updating a bunch of packages I'm getting this error message when I try to open an associated file via a reference:

[cite:@key]

Before it was working fine via emark either by clicking on the reference or by running embark-act on it. Now I get this instead:

citar--library-file-action: Symbol’s function definition is void: open

Any suggestions?
