A racket library for adding hygiene to reader extensions
documentation: http://docs.racket-lang.org/hygienic-reader-extension/index.html
(extend-reader reader-proc extend-readtable) → (-> A ... Any)
reader-proc : (-> A ... Any)
extend-readtable : (-> Readtable #:outer-scope (-> Syntax Syntax) Readtable)Extends the given reader-proc by making a function that calls it
with the current-readtable parameter extended with extend-readtable.
In addition to a readtable, it passes an outer-scope argument to the
extend-readtable function, which that function can pass into the
readtable procedures it adds. Those readtable procedures should use
the hygienic-app function to transform any input syntax objects into
the output syntax.
(hygienic-app proc stx #:outer-scope outer-scope) → Syntax
proc : (-> Syntax Syntax)
stx : Syntax
outer-scope : (-> Syntax Syntax)Applies proc to stx, but with extra scopes added to the input and
output to make it hygienic.
This is meant to be used within a readtable-proc added using the
extend-reader function, and the outer-scope argument should come
from the outer-scope argument passed to the extend-readtable
argument to that function.
