This module provides tools for port I/O.
This library is unstable;
compatibility will not be maintained.
See Unstable for more information.
(read-all [reader port]) → list? |
reader : (-> any/c) = read |
port : input-port? = (current-input-port) |
This function produces a list of all the values produced by calling
(reader) while current-input-port is set to port, up
until it produces eof.
Examples: | ||||||
|
(read-all-syntax [reader port]) → (syntax/c list?) |
reader : (-> (or/c syntax? eof-object?)) = read |
port : input-port? = (current-input-port) |
This function produces a syntax object containing a list of all the syntax
objects produced by calling (reader) while current-input-port
is set to port, up until it produces eof. The source location
of the result spans the entire portion of the port that was read.
Examples: | ||||||||||||||
|
(port->srcloc port [source span]) → srcloc? |
port : port? |
source : any/c = (object-name port) |
span : exact-nonnegative-integer? = 0 |
Produces a srcloc structure representing the current position of a
port, using the provided source and span values to fill in
missing fields. This function relies on port-next-location, so line
counting must be enabled for port to get meaningful results.
Examples: | ||||||||||
