For my work i need a custom cite command, which creates a footnote with a custom style. For that i use the \DeclareCiteCommand command:


The footnote itself works, however there is a [ at the beginning of the footnote, which looks like this:

enter image description here

The [ appears when i use [\unspace], however if i remove it, there is an empty row with only a dot in it between the footnotes:

enter image description here

Is there a way to have the footnote without the [ and no empty rows? I'm not working with LaTeX for a long time, so i could not figure it out myself and didn't find any questions like that

  • Try wrapping the \unspace within {} instead of [] (cf. page 176 of the BibLaTeX manual for version 3.14). Please provide a minimal working example, so that suggestions like this can be easily tested.

  • using {} instead of [] result in the empty rows with dots like in the Question

Perhaps you are looking for something like the following

Sample output









\DeclareCiteCommand takes five mandatory arguments and only one optional one. Your syntax with [\unspace] looks like a second optional argument, but was being read as the first three mandatory arguments [, \unspace and ]. The spaces in your output were being added by end of line characters, which you need to comment out with % at appropriate places.

I have tried to guess how you might want to use the prenote.

  • It works thank you so much :) i was really frustrated because it didn't work for me. but your solution works exactly how i wanted it to be.
