edt: Changes
1.2 What’s New in Version 4.0
=============================
Version 4.0 contains the following enhancements:
1. Scroll margins at the top and bottom of the window are now
supported. (The design was copied from ‘tpu-extras.el’.) By
default, this feature is enabled with the top margin set to 10% of
the window and the bottom margin set to 15% of the window. To
change these settings, you can invoke the function
‘edt-set-scroll-margins’ in your ‘.emacs’ file. For example, the
following line
(edt-set-scroll-margins "20%" "25%")
sets the top margin to 20% of the window and the bottom margin to
25% of the window. To disable this feature, set each margin to 0%.
You can also invoke ‘edt-set-scroll-margins’ interactively while
EDT Emulation is active to change the settings for that session.
*Please note:* Another way to set the scroll margins is to use the
Emacs customization feature to set the following two variables
directly: ‘edt-top-scroll-margin’ and ‘edt-bottom-scroll-margin’.
Enter the Emacs ‘customize’ command. First select the ‘Editing’
group and then select the ‘Emulations’ group. Finally, select the
‘Edt’ group and follow the directions.
2. The ‘SUBS’ command is now supported and bound to ‘GOLD-Enter’ by
default. (This design was copied from ‘tpu-edt.el’.) Note, in
earlier versions of EDT Emulation, ‘GOLD-Enter’ was assigned to the
Emacs function ‘query-replace’. The binding of ‘query-replace’ has
been moved to ‘GOLD-/’. If you prefer to restore ‘query-replace’
to ‘GOLD-Enter’, then use an EDT user customization file,
‘edt-user.el’, to do this (
Customizing).
3. EDT Emulation now also works in XEmacs, including the highlighting
of selected text.
4. If you access a workstation using an X Server, observe that the
initialization file generated by ‘edt-mapper.el’ will now contain
the name of the X Server vendor. This is a convenience for those
who have access to their Unix account from more than one type of X
Server. Since different X Servers typically require different EDT
emulation initialization files, ‘edt-mapper.el’ will now generate
these different initialization files and save them with different
names. Then, the correct initialization file for the particular X
server in use is loaded correctly automatically.
5. Also, ‘edt-mapper.el’ is now capable of binding an ASCII key
sequence, providing the ASCII key sequence prefix is already known
by Emacs to be a prefix. As a result of providing this support,
some terminal/keyboard/window system configurations, which don’t
have a complete set of sensible function key bindings built into
Emacs in ‘function-key-map’, can still be configured for use with
EDT Emulation. (Note: In a few rare circumstances this does not
work properly. In particular, it does not work if a subset of the
leading ASCII characters in a key sequence are recognized by Emacs
as having an existing binding. For example, if the keypad 7
(<KP7>) key generates the sequence ‘<ESC>Ow’ and ‘<ESC>O’ is
already bound to a function, pressing <KP7> when told to do so by
‘edt-mapper.el’ will result in ‘edt-mapper.el’ incorrectly mapping
‘<ESC>O’ to <KP7> and ‘w’ to <KP8>. If something like this happens
to you, it is probably a bug in the support for your keyboard
within Emacs *or* a bug in the Unix termcap/terminfo support for
your terminal *or* a bug in the terminal emulation software you are
using.)
6. The ‘edt-quit’ function (bound to ‘GOLD-q’ by default) has been
modified to warn the user when file-related buffer modifications
exist. It now cautions the user that those modifications will be
lost if the user quits without saving those buffers.
