There are a couple of things that are unclear to me after reading the manual for GNU refer. I have been toying with it with limited success.
So these are my questions: 1. How do I change the label expression conditionally? 2. How do I make the citation appear in the footnotes with only a superscript number in the text? 3. Is it possible to modify the references section to include a page number for every time a reference was cited? 4. How do I delete the parentheses surrounding citations to more than one source? *Conditional label expressions.* In the refer documentation, there are five types of citation: Type 0: if the reference doesn't trigger the other types > Type 1: If it has a J field > Type 2: if it has an I field > Type 3: if it has a B field > Type 4: if it has a G or R field And the label command between .R1 and .R2 applies to every citation beneath it until the next .R1/.R2 block. *Conditional based on type.* I generally only cite two or three types of reference (cases, court rules, and statutes), but there are *many *types of reference in the law, and they all have particular styles. There are also rules about citation styles when citing to a source that has already been cited. Therefore, I would like to have another field, %Y(type), in the .ref file, and have refer choose the label expression based on the content of that field. Is that doable? *Conditional based on repetition.* I know that I can use the # flag to trigger the short style of the citation with refer, but the rule in my citation style is to use the long style the first time a reference is cited and the short style or ibid style for every subsequent reference. How can I trigger the short style or ibid style programmatically? *Citation footnotes* Another thing I could not find in the documentation is how to make a footnote of the reference with a superscript number as the label in the text and the full citation as the label in the footnote, kind of like how Wikipedia does it. I've tried a couple things, but I could not figure out how to get that behavior *Parentheses around multiple citations in text* For some reason, when I do multiple citations in a row, if I do not add my own argument to .[ or .], groff puts parentheses around the label. Because the delimiter for US legal citations is a semicolon, I can suppress that by just putting a semicolon after the .] of all but the last citation. However, that is inconvenient for moving things around later because I will not want a semicolon after every citation. So how do I stop the ( citation) and make it use only ;? *The references section* *Changing the label style in the references section.* If I do not do the no-label-in-references command, the references section has a completely different label style from the style I defined in the label expression. How do I change the style used in that REFERENCES section? *Putting page numbers in the references section.* In legal briefs, in the references section, we put each page number on which a reference was cited. I also like to break that down into a cases section, a rules section, and a statutes section (another reason for the %Y field, I think). Is it possible to have refer add a reference for page numbers to be collected and placed by groff in the references section for every citation in text?
