Right -- there's currently no way to lift a module declaration after
expansion starts working on expressions within a module.
I think that operation could be added, and I'll look into it as soon as
possible.

I've changed esc;w so that it disables the anchor.
Meanwhile, I would welcome someone who wanted to take on the task of a more

Which lifting function? All of the ones I found didn't do what I
needed when called from an expression context, as the lifted syntax
was also in expression context. (syntax-local-lift-expression, and
syntax-local-lift-module-end-declaration)

I notice that there are many keystrokes missing in emacs keybindings.
Besides this copy-clipboard (M-w) does not work like in emacs. When I mark
a region and press Alt-w, the editor does not exit select mode. This means
that I am not able to move to another place and paste the selected region.

That's the right idea, but the "libsqlite3" is also needed for Mac OS X
PPC.
I think that
(define-runtime-path sqlite-path
(case (system-type)
[(windows) '(so "sqlite3")]
[else '(so "libsqlite3")]))
is probably best, along the same lines as `openssl/libcrypto`.

Lift the module definition to top and require in the expression position?

I dont think there's any way to specify the alignment of the entire
slide. You'd have to do each element separately.
For example, using
(para "Please align left")
as the title would align left and
(para #:align 'right "Please align left")
would align right.
If all your slides have the same st
> I tend to just use (vl-append gap-size items ...)
That doesn't align left relative to the entire slide. You'd have to
wrap a para or something else around it.
Here is a super basic macro that aligns-left everything on a slide:
(define-syntax-rule (left-slide title x ...)
(slide #:title (para
In complement, note that it's quite common to use (item "Some text") and
(subitem "One precision: ..."), which are left-aligned (but, like `para',
has a #:align keyword for another kind of alignment).

Hi all,
I am writing for a presentation using Slideshow. I want to align picts left.
But it aligns center. Below is my code

Matthew,
I think the problem may be that "#lang" is triggering a search for
`slon/main` before falling back to `slon/lang/reader`, and since no
`slon/main` is embedded, the attempt looks for a "slon" collection. The
"#lang" search continues as it should when an "slon" collection is
found and no
Currently we do not have a safe way of checking #:property options in
TR, so writing the struct in R and requiring it is the only solution
right now.

Matthew,
Assuming that this module is `slon/lang/reader`, does it help to add
++lib slon/lang/reader
to the `raco exe` command, along with the `++lib` argument that you
have already?
Unfortunately, no. Nothing has changed:
$ raco exe ++lib slon/slon-language ++lib slon/lang/reader slon

Matthew,

Is that reader in a `reader` submodule, or is it in a separate
".../lang/reader.rkt" module file?
In a separate file:
$ cat lang/reader.rkt
(module reader syntax/module-reader
#:language 'slon/slon-languag
You have a reader for your language that is triggered by "#lang",
right?
Is that reader in a `reader` submodule, or is it in a separate
".../lang/reader.rkt" module file?
