Allowing them would require support for immutable fxvectors and
flvectors, interning, and more. Since the motivation for reader
support is to make marshaling and unmarshaling easier, allow
them only in `read' mode. Change printing to make then unquotable.
More generally, a `splicing-syntax-parameterize' wrapping immediate
compile-time code effectively parameterizes the compile-time code as
well as any macro-triggered compile-time code. This is implemented by
using a compile-time parameter that complements each syntax binding.
Use `raise-user-error' for `raco pkg ...' errors, so that stack
traces don't print out for external errors. Reformat error messages
generally to match current conventions. Use logging for debugging
output.
The default `raco pkg' mode should work right for a
multiple-version installation (because everything in
Racket should work in a multiple-version installation).
Along the same lines, `raco pkg' should work if the
installation directory is unwriteable. So, the default
mode is user-specific and version-specific.
Use `--shared' or `-s' for user-specific, all-version
installs.
By default, `raco pkg show' now shows packages installed
in all three modes (installation-wide, user- and version-
specific, and user-specific all-version). Use `-i', `-u',
or `-s' to show just one of them.
For now, "METADATA.rktd" is still recognized as a fallback.
Also, rewrite package source type and name inference,
make ".zip" the default format for `raco pkg create',
and many doc edits.
Now works with the handler argument omitted, in which case
the default handler is used. Note that the default handler
cannot be used in conjunction with the default prompt tag
because it is unsound to do so.
Change `bit-vector-count' to `bit-vector-length', add arguments
to `bit-vector-copy', use `racket/private/vector-wraps' (which
should be moved to a public place) to implement things like
`for/bit-vector'.
Handle close parentheses in a smarter way while in
auto-parens mode and be a little more smart about
inserting brace pairs in general.
In summary:
- Add some "smart-skip" behavior to insert-close-paren,
described in the documentation.
- When auto-parens mode is enabled,
the existing "balance-parens" keybinding invokes
insert-close-paren with a smart-skip argument of
'adjacent
- A new "balance-parens-forward" keybinding invokes
insert-close-paren with a smart-skip argument of
'forward (whether or not auto-parens mode is
enabled)
- Enable basic smart-skip behavior for
strings ("...") and |...| pairs, specifically, typing
a double-quote or bar character when the cursor
immediately precedes one causes the cursor to simply
skip over the existing one
- Tweak auto-insertion of block comment pairs; i.e.
typing hash and a bar results in a properly balanced
#||# pair. Also, when you type a bar character when
the cursor immediately precedes a closing bar and
hash of a comment, then the cursor skips over both
characters (this seems better than having it just
skip over the bar, and then having to introduce a
new keybinding to detect when a hash is typed while
the cursor is between a bar and a hash)
- In strings and line/block comments, auto-parens mode
no longer has any effect (you can still use the M+..
keybindings to force insertion of a particular brace
pair)
- Detect when a character constant is being typed, and
don't insert brace pairs if so; i.e. if the cursor
is immediately after #\ , then typing any open parens,
double quote, or bar, does _not_ result in the
insertion of an open/close pair even in auto-parens
mode
- Add a bunch of tests related to auto-parens, matching
pairs of braces, strings, comments, etc. to
collects/tests/framework/racket.rkt
Changes the implementation of highlight-range so that it
only recomputes all of the new locations from the positions
when on-reflow is called (otherwise only computing the
relevant ones) and make the on-reflow callback chop itself
up, in case there are lots of highlighted ranges to avoid
tying up the event loop.
Changes searching so that it doesn't neccessarily compute
the entire search results in a single event callback
(but also make it start the computation more aggressively)
Overall, this changes the strategy from one that, for any potentially
long-running callback, just tried to push it off into the future, into
a strategy that tries to avoid long-running callbacks by breaking the
work up into chunks, but starting the first chunk immediately (in a
low-priority callback).
Also, misc other changes to make this work better and generally clean
things up.
