@; to associate `history` to the right package:

@(declare-exporting compiler/commands/read)
|
|
|
|
The @exec{raco read} command @racket[read]s and pretty-prints the
|
|
contents of the given files. This command is useful for showing
|
|
how a @tt{#reader} or @hash-lang[]-based reader extension converts
|
|
input to an S-expression. It is also useful for pretty-printing a term
|
|
that is already in S-expression form.

Command-line flags:

|
|
|
@itemlist[
|
|
@item{@Flag{n} @nonterm{n} or @DFlag{columns} @nonterm{n} --- format output for a display with @nonterm{n} columns}
|
|
@item{@Flag{h} or @DFlag{help} --- show help information for this command}
|
|
@item{@DFlag{} --- do not treat remaining arguments as switches}
