this means that various things that try to color and otherwise show info by
changing the way the editor looks no longer need to worry about whether it
is locked and delay things in some complicated way. also, this means that
users can edit while drracket is running the program which is hopefully
less confusing.
The change allows `raco setup' to reach a fixed point under Windows
for "redex/examples/cont-mark-transform".
I'm more and more convinced that `normal-case-path' is never
a good idea. In some cases, maybe it's good to recognize a
few extra equivalences, but it works badly when paths are taken
from many sources and are not consistently normalized. It's better
to just preserve case.
For basic normalization, `simplify-path' is the right choice. Use
inode identity (as `raco setup' does) when anything stronger
than `simplify-path' is needed.
The format previously included relative paths in the syntax
of the platform used to run `raco setup'. While a "cache.rktd"
built on Unix would work for Windows, the reverse would not
be true. Also, `raco setup' under Windows would get confused
because it would arrive at different relative paths for the
same collection (e.g., "drracket/private" and "drracket\\private").
The portable representation of relative paths is also
normalized.
A "cache.rktd" file still has absolute paths for Planet packages
or links installed with `raco link', but that's not a problem for
packaging a distribution with a portable "cache.rktd".
Also, `raco setup' cleans "cache.rtkd" by removing collections
that are omitted and by not including collections that have no
"info.rkt"/"info.ss" file.
Plus minor cleanups:
- fixed indentation
- removed useless gen-create-place function
- avoid using the guard position of syntax-case
- drop useless datum->syntax call (it returns syntax
objects unmodified and generate-temporary
returns a syntax object)
- "interal" => "internal"
- minimized the generated code (move into a function call)
- check to make sure constructed lambda expression is well-formed
- check to make sure 'place' is used inside a module (or else
several other things it use will fail)
