presentation-replace-output & clim:*command-unparser*
Date: Thu, 11 Jun 1992 14:38 EDT
I'm using CLIM 1.0 and MCL 2.0b1p3 and have two questions.
The first concerns presentation-replace-output. I have the following code:
(clim:presentation-replace-input stream chosen-object type clim-view
:buffer-start (1- (clim::input-position stream)))
; OBS! I'm using a undocumented clim function ^^^^^^^^^^^^^^^^^^^^
The function is documented to have a :buffer-start keyword which tells
which part of the buffer to replace. The default is
(clim::input-position stream), but I want to erase the last character,
hence the use of 1-. The problem is that clim::input-position is
undocumented, can I have the same effect using a documented function.
It seems strange to document the keyword argument when there is no
useful documented way of using it.
It's exported in CLIM II.
The second question concerns unparsing commands. I read commands
myself and want to echo them using the standard unparser:
(funcall clim:*command-unparser* (clim:find-command-table
However, I get an error:
> Error: value NIL is not of the expected type
> While executing: CLIM:EXPAND-PRESENTATION-TYPE-ABBREVIATION
> Type Command-. to abort.
See the RestartsI menu item for further choices.
The backtrace reveals a call to clim:present that somehow gets nil as
the type specifier. A have checked that the command given to the
unparser is a legal command. Am I using the clim:*command-unparser*
wrong? In case, what should I do? Bug? Where?
Why not just use this:
(present command `(command :command-table ,(frame-command-table frame))
