How to set up definitions (as in LaTeX) in scribble?

Questions & Answers
1

I am trying to use scribble to write a technical document, with "defined terms". I would like in one place to be able to make a definition and give it a tag, and then refer to that tag elsewhere (perhaps in the same doc, perhaps from another doc).

So something like this:

@definition[#:tag "partition"]{A @dt{disk partition} is a separated part of physical memory, defined in the partition table.}
... elsewhere
See @defref["partition"] for more details.

I am completely new to scribble and racket, but I have read parts of the documentation. I can see that section and secref resemble what I want, and that I'll probably need a new "tag type" (like 'part is used for sections). But I'm struggling to understand how to actually extend scribble in this way. I get that I probably need to define a new function, but how do I "hook in" to the tagging system?

Would elemtag and elemref do what you want?

Is the tech form sufficient? Along with deftech? See 4.2.7 Links

Thank you both. tech seems like exactly what I need! I'm a bit confused by the syntax. I can get it working just fine within a single document. I tried calling it from another file with

@tech[doc: '(lib "the-other-file.scrbl")]{field}

and it just renders with a "badlink" but no error. I get the same if I just put #:doc "the-other-file.scrbl". I could only find this cheat sheet to see how it works: Scribble Cheatsheet

I also noticed that I didn't get any warning when the ref was missing (if I made a typo). I do get a warning when I use secref with a section that

It may help.

You should only need #:doc if the definition of the term is in a different Scribble document, not if it is merely in a different file that ends up in the same document, e.g. via include-section.

Indeed, the distinction between document and file-on-disk is not unique to Scribble, but it did confuse me at first. When do I need special work for cross-references? When not? Depends on the document :slight_smile:
