The new names are `prompt-tag/c` and `continuation-mark-key/c`
to keep the names consistent with the values that are being
contracted. Also updated the HISTORY file.
Add `raise-argument-error', `raise-result-error', `raise-arguments-error',
and `raise-range-error'.
The old convention was designed for reporting on a single (sometimes very
long line). The new convention is
<name>: <short message>
<field>: <detail>
...
If <detail> is long or itself spans multiple lines, then it may
also use the form
<field>:
<detail>
where each line of <detail> is indented by 3 spaces.
Backtrace information is shown as a multi-line "context" field.
This reverts commit f3b687c8ed.
After discussion with Robby and Stevie, we concluded that
this procedure isn't necessary for now. If we ever think
of more examples where it's useful we can bring it back.
a chaperone contract", "no it definitely isn't" or "evaluate this code
at runtime to find out"; previously only the first two options
were available to opters
(this commit also includes other tweaks here and there so won't stand alone)
library (mostly in opt/c)
Specifically:
- add inlining declaration for ->i helper function
- modernized the opt/c contracts and improved them so that mutually
recursive define-opt/c functions recognize each other instead of
bailing out to the slow path.
- added =/c as an optimized contract
- improve the error message for the between and comparison opt
contracts
- adjust the blame struct so the name is created lazily, since opt/c
contracts just stick a copy o the contract into the thunk that
creates the name and we don't want to run those effects twice if we
can help it.
adjust 'one-of/c' and 'symbols' so they just use or/c (when possible)
improve or/c's stronger check so that, in the case that or/c is
getting eq or equal contracts, or/c's stronger check is as good as
'symbols'/'one-of/c's stronger check is.
change the implementation to special case struct procedures and to use
it in provide/contract.
This speeds up the rendering phase of the Guide documentation by more than 2x.
Thanks to Matthew for spotting the opportunity!
and documented and adjusted these libraries:
racket/contract/base
racket/contract/exists
racket/contract/parametric (renamed from exists)
racket/contract/region
