Re: [pollen] Excessive spaces in pre
One can also produce the same behavior in `#lang scribble/text`:
#lang scribble/text
@(require pollen/template/html)
@(define (test)
(->html `(pre " 1\n 2\n 3\n 4")))
@(define (iden . s) s)
@iden{@(test)}
Given that this is not a Pollen problem per se, you might get a more satisfying
answer by posting on issue on the `racket/scribble` repo (I do, sometimes) and
see what they say. If the scribble authors agree it's a bug, and repair it,
then the fix will flow into Pollen too.

[pollen] Re: Excessive spaces in pre
Kind of. Here's an example:
@(define (test)
(->html `(pre " 1\n 2\n 3\n 4")))
@(define (iden . s) s)
@iden{@(test)}
which results in
1
2
3
4
while
@(define (test)
(->html `(pre " 1\n 2\n 3\n 4")))
@(define (iden . s) s)
@iden{@(test)}
results in:
1
2
3
4

Out of curiosity, why would you use that, rather than the `here-path` value in
`metas`?

I would probably convert `image` into a macro that expands into a function call
that secretly passes `here-path` as an argument. An example of this approach:

I agree that it's confusing if you don't know to expect. But does it
surface in any situation other than the slightly oddball case of putting
spaces in front of a `when/splice`?

[pollen] How to access a pollen source's path in pollen.rkt
Hello everyone —
Is there a way to access a pollen file's source path directly in the
pollen.rkt?
I know it's possible to pass it in using (current-contract-region), but
that's a bit unwieldy.
Example: you define an ◊image function in pollen.rkt that pulls in images
from different directories based on which chapter the current pollen source
belongs to. You'd rather not have to call
◊image[(current-contract-region)]{hamster.jpg} because it ruins the
aesthetic grace of your pollen file ;)
Is there a module I can require in pollen.rkt that will help me out?
Any suggestions warmly appreciated!
-A
