3.3.2 mischief/dye-pack: Protecting Syntax Objects
| (require mischief/dye-pack) | package: mischief |
parameter
(current-dye-packs stx) → void? stx : syntax?
Stores the syntax object used for arming and disarming dye packs in the current
syntax transformer.
procedure
(call-with-disarmed-dye-packs stx proc [ #:inspector inspector]) → any stx : syntax? proc : (-> syntax? any) inspector : (or/c inspector? #false) = #false
Calls proc with a version of stx whose dye packs are disarmed
using insp. Stores the original stx in
current-dye-packs during the execution of proc.
Equivalent to:
(parameterize {[current-dye-packs stx]} (proc (syntax-disarm stx inspector)))
syntax
(with-disarmed-dye-packs name-id stx-expr body ...+)
Executes body with name-id bound to a disarmed version of
stx-expr using the declaration inspector for the enclosing module.
Stores the value of the original stx-expr in
current-dye-packs during the execution of proc.
Equivalent to:
(call-with-disarmed-dye-packs stx-expr #:inspector (module-code-inspector) (lambda {name-id} body ...))
procedure
(rearm-dye-packs stx [ #:dye-packs dye-packs #:mode mode]) → syntax? stx : syntax? dye-packs : syntax? = (current-dye-packs) mode : any/c = #false
Produces a version of stx in which the dye packs on dye-packs
are rearmed. If mode is #false, always rearms the dye packs
for the whole syntax object. If mode is a non-symbol true value, the
dye packs are pushed to nested syntax objects in accordance with the
'taint-mode syntax property. If mode is a symbol, sets the
'taint-mode property of stx to mode and then rearms
according to it.
