The generics library now generates a `name/c` macro
for a generic interface `name`. The combinator can be
used to contract instances (or constructors) of a
generic interface across standard contract boundaries.
See PR 12860; some of problem related to the PR were "fixed" by
adjusting the guarantees that are specified in the documentation.
Another problem was that non-consecutive bytes could be returned.
For all currently supported platforms, the result was already
portable, despite the documentation's hedging.
Also fixed up the documentation in other ways, such as the fact
that `seconds->date' returns a `date*'.
* The old function was removed completely, people will get it from
`racket/base' anyway.
* I also removed its documentation. I thought about leaving a note in,
but if `define-ffi-definer' is the preferred style, then this should
be done when there's a way to make `define-ffi-definer' use it. (Eg,
some new #:keyword that adds a way to change the defined name.)
* Note that the function is added to `racket/private/string' and not to
`racket/string' because the latter deals only with strings, and the
new function accepts byte strings too. It might be better to start a
new `racket/regexp' module for these functions.
Add extra intitial-message lines, use "..." on a field name
to indicate that it could reasonably be hidden by default,
and refine some existing messages.
Includes the addition of 'overflow and 'start-overflow-work
events, whcih are effectively specializations of 'sync and
'start-work to expose overflow handling.
Also, fix a bug related to a potential GC during mark-stack
restore from a lightweight continuation.
- added some color (mostly to try to disambiguate the lines)
- several of the things named '*-element' actually belong under content, not element.
- element has 'content', not the substructs.
- convertible?s are content's.
- the 'content' field in an element is not a list, but simply a content.
- there are a bunch of things under target-element.
- image-element was missing fields
- collect-element was missing the collect field
For example, a syntactic form box is labeled with "SYNTAX". Forms
such as `defform' and `defthing' now support a `#:kind' option
for setting the label.
Added alises for call-with-continuation-prompt,
abort-current-continuation, and call-with-composable-continuation.
Also allow % and fcontrol to take an optional prompt tag argument.
Revise the subword matching to have three different levels for full
match (= a permutation of the input), a generic match for all parts, and
everything else.
Instead of just one array for exact results and one for all the rest,
use one array for each possible comparison result, and concatenate them
all for the final list.
