tweaks: remove unneeded settings and unsettings of MULTIBUFFER
...
In the preceding commit, open_buffer() was changed so that it gets
told whether to load into a new buffer or not, so it is no longer
needed to convey this information through a flag.

input: do not crash if sctofunc() returns NULL

This fixes a regression introduced by commit 54103d8e: a crash that
can be triggered by running 'nano --restrict' and pressing <Insert>.

This assumes that all movement functions are located together,
starting with to_first_line() and ending with do_right().

tweaks: refactor the implanting of a key expansion
2018-02-27 13:34:32 +01:00
01457ae3d3
input: handle the implant() function separately, as it is special
...
The implant() function itself cannot be bound to anything, so it
is not in the linked list of functions -- trying to find it would
lead to a NULL pointer, and thus to a segfault.
This fixes https://savannah.gnu.org/bugs/?53233 .
2018-02-27 11:11:02 +01:00
54103d8ed1
tweaks: elide another variable, to call a function less often
...
Instead of always calling sctofunc(), it is now only called when
in view mode OR when (after the keystroke's function has been run)
no need for a refresh has been established yet.
2018-02-25 10:41:51 +01:00

The new option 'set errorcolor' allows the user to specify the color
combination for the status bar when an error message is displayed.
2018-02-23 12:35:17 +01:00
28933cf572
tweaks: remove two superfluous checks, and restrict two others
...
When 'refresh_needed' is already TRUE, there is no need any more
to check whether it should be set.
[Those first two calls are leftovers from before the time that
reset_multis() morphed into check_the_multis().]
2018-02-14 17:29:59 +01:00
7a038adfd4
input: don't stop prepending when the user adds text via a shortcut
...
When characters are added via Verbatim Input or by pressing <Tab>,
the prepend flag should be retained, just like when characters are
typed directly.

new feature: allow binding a key to a string (in a nanorc file)

In this way a single keystroke can produce a fragment of text or a
series of commands, or a mix of the two. It is like a prerecorded
macro.
This fulfills https://savannah.gnu.org/bugs/?52931 .
