@{Use this function to expand the contents of the definitions
window for use with external program processing tools.
This function uses
@scheme[drscheme:eval:build-user-eventspace/custodian]
to build the user's environment.
The arguments @scheme[language-settings], @scheme[init], and
@scheme[kill-termination] are passed to
@scheme[drscheme:eval:build-user-eventspace/custodian].
The @scheme[input] argument specifies the source of the program.
The @scheme[eval-compile-time-part?] argument indicates if
@scheme[expand]
is called or if
@scheme[expand-top-level-with-compile-time-evals]
is called when the program is expanded.
Roughly speaking, if your tool will evaluate each expression
itself by calling
@scheme[eval]
then pass @scheme[#f]. Otherwise, if your tool
just processes the expanded program, be sure to pass
@scheme[#t].
This function calls
@method[drscheme:language:language<%> front-end/complete-program]
to expand the program. Unlike when the @onscreen{Run} is clicked,
however, it does not call
@method[drscheme:language:language<%> front-end/finished-complete-program].
The first argument to @scheme[iter] is the expanded program
(represented as syntax) or eof.
The @scheme[iter] argument is called for each expression in the
expanded program and once more with eof, unless an error is
raised during expansion.
It is called from the user's thread.
If an exception is raised during expansion of the
user's program, @scheme[iter] is not called.
Consider setting the exception-handler during @scheme[init] to
handle this situation.
The second argument to @scheme[iter] is a thunk that
continues expanding the rest of the contents of the
definitions window. If the first argument to @scheme[iter] was
eof, this argument is just the primitive
@scheme[void].

kill this custodian, but it can safely be shutdown (with
@scheme[custodian-shutdown-all]) after the
expansion is finished.
It initializes the
user's eventspace's main thread with several parameters:
@itemize[
@item{ @scheme[current-custodian] is set to a new custodian.
}@item{
In addition, it calls
@scheme[drscheme:eval:set-basic-parameters].
}]
The @scheme[language-settings] argument is the current
language and its settings. See
@scheme[drscheme:language-configuration:make-language-settings]
for details on that structure.
If the program is associated with a DrScheme
frame, get the frame's language settings from the
@method[drscheme:unit:definitions-text<%> get-next-settings]
method of
@scheme[drscheme:unit:definitions-text<%>]. Also, the most recently chosen language in
the language dialog is saved via the framework's
preferences. Apply
@scheme[preferences:get]
to
@scheme[drscheme:language-configuration:get-settings-preferences-symbol]
for that @scheme[language-settings].
The @scheme[init] argument is called after the user's parameters
are all set, but before the program is run. It is called on
the user's thread. The
@scheme[current-directory] and
@scheme[current-load-relative-directory]
parameters are not set, so if there are appropriate directories,
the @scheme[init] argument is a good place to set them.
The @scheme[kill-termination] argument is called when the main thread of
the eventspace terminates, no matter if the custodian was
shutdown, or the thread was killed. This procedure is also
called when the thread terminates normally. This procedure is
called from a new, dedicated thread (@italic{i. e.}, not the thread
created to do the expansion, nor the thread that
@scheme[drscheme:eval:build-user-eventspace/custodian] was called from.)})
