I have written the following code, borrowing parts from other commands:
;;;StartBookpart
(let ((tag "StartBookpart")(thetitle ""))
(d-DirectivePut-movementcontrol-override tag (logior
DENEMO_OVERRIDE_GRAPHIC DENEMO_OVERRIDE_TAGEDIT))
(set! thetitle (d-GetUserInputWithSnippets (_ "Start Bookpart")(_
"Give chapter title::") thetitle))
(disp thetitle)
(if thetitle
(begin
(d-DirectivePut-movementcontrol-prefix tag (string-append "
\\bookpart { %start of
bookpart\n \\header {\n title = {" thetitle "}\n }\n"))
(d-SetSaved #f)
)
(d-InfoDialog "Cancelled")
)
)
However, if I insert, e.g., Titletext in the dialog, it returns
(Titletext . \line\large{Titletext}
)
(this is what (disp thetitle) outputs), and (string-append ) gives an
error that that is not a string. How can I access the unprocessed input?
Moreover, when the user calls StartBookpart a second time I want to fill
the input field with the previous title. To this end, the clean title
has to be saved somewhere (or the generated code has to be parsed). How
can that be done?
