|
|
|
|
The @web-server provides a means of running Scheme servlets
|
|
from within DrScheme, or any other REPL.
|
|
|
|
@file{servlet-env.ss} provides the servlet API from @file{servlet.ss}
|
|
as well as the following special forms:
|
|
|
|
@defform[(on-web servlet-expr)]{This expands to @scheme[(on-web 8000 servlet-expr)].}
|
|
|
|
@defform[(on-web port servlet-expr)]{
|
|
This constructs a small servlet, where the body of the @scheme[start] procedure is
|
|
@scheme[servlet-expr], runs the @web-server on port @scheme[port], and opens
|
|
a browser to a URL accessing the constructed servlet. The call blocks until the
|
|
servlet finishes its computation, i.e. @scheme[servlet-expr] is evaluated, and
|
|
returns its result. @scheme[servlet-expr] may use the entire Scheme servlet API.
