Re: [racket-users] Export indentation preferences in a package's info.rkt?
IMO, the truly Racket-y way would be to attach a syntax property to the exported identifier that has information about how it should be indented. This is actually a major improvement over the current way DrRacket handles indentation because it would handle forms by their syntactic binding rather than by datums. That means that: 1. Multiple forms could have the same “name” and have different indentation. 2. Forms imported with rename-in, prefix-in, etc. would be indented properly. 3. Indentation settings come from the forms themselves rather than some unrelated configuration settings. I think all of those things are big wins over datum-based configuration. However, the obvious problem is that it means bindings need to be resolved before indentation settings can be retrieved since the binding needs to be resolved to access its syntax properties. In DrRacket, I wonder if this could work similarly to the recent improvement to blueboxes: IIUC, they work by binding now, but they perform some caching/guessing so that documentation can still be resolved before background expansion finishes. Leveraging the same technique would probably work for indentation information. Alexis -- You received this message because you are subscribed to the Google Groups Racket Users group.

Re: [racket-users] Export indentation preferences in a package's info.rkt?
I agree this would be nice but I think the right way to approach it would be to have metadata cached (via some more generic library supporting such metadata) with exported libraries in a file near the .zo and .dep files. Then drracket can figure out what is imported and then read those files for things like indentation. And, of course, there are likely to be other uses of such metadata.

Re: [racket-users] Export indentation preferences in a package's info.rkt?
In Emacs:
- Emacs Lisp (Elisp) macros can use a `declare` form to attach
metadata, including indentation info:
https://www.gnu.org/software/emacs/manual/html_node/elisp/Declare-Form.html
- Other (external) Lisp language modes have a convention that there's
an Elisp {lisp,scheme,racket}-indent-function that does indentation,
and, it looks for a property list, where the key is the name of a
macro and the value is usually a number. Users can at least tweak this
in their Emacs init file. For example for racket-mode:
https://github.com/greghendershott/racket-mode/blob/master/Reference.md#racket-indent-line
For Racket:
- I like the idea of collections being able to provide indentation
info for special forms.
- I'd like the info to be easily accessible to both DrRacket and other
tools (including but not limited to racket-mode :)).
- Off the top of my head, it doesn't seem very Rackety to give
functions a runtime blob of metadata.
- Probably a more Rackety way to do this would be in a submodule. Much
like doc, indentation info feels like something that's not about run
time (or even compile time). Doc is about doc time, and indentation
is about edit time (or tool time).
Also, like doc, there's an xref database aspect to this -- given a
namespace and a symbol foo, you want to quickly lookup the indentation
for the correct foo. In fact, maybe doc time vs. edit time is a
distinction without a difference. Maybe the answer is to allow docs to
be more structured -- such as, instead of a blob of HTML, here's the
blue box part, here's the remaining part, here's the (optional, new)
indentation value, and so on. [It could still be a blob of HTML, I
guess -- just one tagged more finely ala so-called semantic HTML.]
Sorry that turned into a longer ramble than I expected.

[racket-users] Export indentation preferences in a package's info.rkt?
I find it irritating when I have to repeatedly add various macros exported by libraries to their proper group in the Indenting section of DrRacket's settings so that they're properly formatted. Is there a way for a package's info.rkt to specify default indentation preferences for it's macros for DrRacket to make sense of? If not, would that be something easy enough to do and useful enough to be worth doing? -- You received this message because you are subscribed to the Google Groups Racket Users group.

I would really like to have such a feature.
