This commit merges changes that were developed in the "racket7" repo.
See that repo (which is no longer modified) for a more fine-grained
change history.
The commit includes experimental support for running Racket on Chez
Scheme, but that "CS" variant is not built by default.
The previous definition of define-simple-macro would fail (with
a very poor error message) if the user made a simple macro like:
(define-simple-macro (~or a b)
(let ([tmp a])
(if tmp tmp b)))
While the define-simple-macro form does allow syntax-parse patterns,
this should not be enabled for the initial head pattern, as described
in the define-simple-macro documentation.
* Update syntax/readerr documentation to match code.
This change simply updates the documentation to match the contract that's actually enforced on `raise-read-eof-error` and `raise-read-error`.
Fixes#1837.
* Fix additional typo noticed by @bennn
As discussed on the racket users list (subj: ~literal vs ~datum) at https://groups.google.com/d/msg/racket-users/KWANfGc7qcI/G_MClWJpBAAJ
New example based on code from Jens Axel Soegaard.
Caveat: I've run this in DrRacket with (require (for-syntax syntax/parse)) to verify the three distinct outputs, but am submitting this PR in-browser, so I haven't run the doc build on it myself.
* Fixed typo in the docs for serialization (serializable-struct/version → serializable-struct/versions)
* Fixed typo in scribble documentation (head pattern → a-pattern)
* Made the order of the argument descriptions match the order of the arguments in the documentation for import and export
* Wrong contract for syntax-local-value in the documentation.
* Clarified signature in documentation for expand-import, expand-export and pre-expand-export
* Corrected typo in documentation for "for".
* Fixed error message for function which seems to have been renamed in the docs
* Fixed typo in a comment in the tests
* Fixed a typo in the documentation for set-subtract.
* Use double ellipses for the free-id-table-set*, free-id-table-set*!, bound-id-table-set* and bound-id-table-set*! operations
* add lang-reader-module-paths to syntax/module-reader
to be used as the third argument to make-meta-reader in lang-extensions
like at-exp
* document lang-reader-module-paths
* use lang-reader-module-paths in at-exp
Changes signatures in `syntax/modcode` to accept `path-string?` arguments
instead of `path?`.
Before, the docs listed `path-string?` but the contracts used `path?`.
Now they agree.
The resolve-module-path-* functions effectively already had a default argument,
which is #f, this allows you to just directly call it with one argument.
