# Wildcard insertions in arara compile instructions

Using arara I would like to know whether wildcard instructions can be passed in the instructions.

I would like to have a dynamic compile of my bu*.aux files when I use bibunits, because as I comment out different sections, the number of files changes constantly.

Short of pointing arara to a custom script written to call bibtex in a for loop for all produced bu*.aux files, does arara have a feature/tool that I have overlooked that would permit this? I.e. I think this similar to this question: Arara rule to delete files with wildcard and Deleting external/auxiliary files?, however, I am not sure whether the custom routine that provides user specified list of file extensions to clean, can be modified to work for the bibunits files. I commented out the lines from the linked question in my MWE arara compile sequence that I am wondering about composing a rule to handle with similar logic.

% arara: xelatex: {synctex: yes}
% arara: bibtex: { files: [ bu1, bu2] }
% !arara: bibtex: { files: [ bu*] }
% !clean: { extensions: [aux, bbl, bcl, blg <and more>] }
% arara: xelatex: {synctex: yes}
% arara: xelatex: {synctex: yes}
