christos | Stop the read module from poking the el_chared.c_macro data structure
currently belonging to the chared module. The read module does so
from three of its functions, while no other module uses the macro
data, not even the chared module itself. That's quite logical
because macros are a feature of input handling, all of which is
done by the read module, and none by the chared module. So move
the data into the read modules's own opaque data structure, struct
el_read_t.
That simplifies internal interfaces in several respects: The
semi-public chared.h has one fewer struct, one fewer #define, and
one fewer member in struct el_chared_t; all three move to one single
C file, read.c, and are now module-local. And the internal interface
function ch_reset() needs one fewer argument, making the code of many
functions in various modules more readable.
The price is one additional internal interface function, read_end(),
10 lines long including comments, called publicly from exactly one
place: el_end() in el.c. That's hardly an increase in complexity
since most other modules already have their *_end() function, read.c
was the odd one out not having one.

christos | From Ingo Schwarze:
* Replace fcns.c by a shorter and simpler func.h
and include it only in the one file needing it, map.c.
* Combine help.h and help.c into a simplified help.h
and include it only in the one file needing it, map.c.
* Check the very simple, static files editline.c, historyn.c, and
tokenizern.c into CVS rather than needlessly generating them.
* So we no longer autogenerate any C files. :-)
* Shorten and simplify makelist by deleting the options -n, -e, -bc,
and -m; the latter was unused and useless in the first place.
* Move the declaration of el_func_t from fcns.h to the header
actually needing it, map.h. Since that header is already
included by el.h for unrelated reasons, that makes el_func_t
just as globally available as before.
* No longer include the simplified fcns.h into el.h,
include it directly into the *.c files needing it.

christos | A very simple, non-intrusive patch to fix a segfault (and a
functional error) in c_gets(), file chared.c.
Run any program using libedit in the default way. At the el_[w]gets()
prompt, invoke ed-command (for example, in emacs mode, press the
escape key, then type the letter 'x'). You should see a ": " prompt.
Type the letter 'x' again. Now press the backspace key a few times,
looking at the screen after each key press:
- The 1st BS deletes the 'x'.
- The 2nd BS deletes the blank after the prompt.
- The 3rd BS deletes the colon of the prompt.
- The 4th BS moves the cursor up one line.
- The 5th BS gives me "Segmentation fault (core dumped)".
Depending on your platform, it might take a few more or a few less
backspaces for the buffer underrun to trigger the segfault, but
you should be able to hit it sooner or later no matter what.
Run the same program again, connect again and invoke ed-command again.
Now type: 'b', backspace, 'i', backspace, 'n', backspace, 'd', enter.
The "bind" command gets executed, even though you deleted what you
typed before hitting enter.

christos | From Ingo Scharze:
Let "el.h" include everything needed for struct editline,
and don't include that stuff multiple times. That also improves
consistency, also avoids circular inclusions, and also makes it
easier to follow what is going on, even though not quite as nice.
But it seems like the best we can do...

christos | cleanup inclusion of histedit.h (Ingo Schwarze)
|
| 1.41 |
| 14-Feb-2016 |
christos | From Ingo Schwarze:
As we have seen before, "histedit.h" can never get rid of including
the <wchar.h> header because using the data types defined there is
deeply ingrained in the public interfaces of libedit.
Now POSIX unconditionally requires that <wchar.h> defines the type
wint_t. Consequently, it can be used unconditionally, no matter
whether WIDECHAR is active or not. Consequently, the #define Int
is pointless.
Note that removing it is not gratuitious churn. Auditing for
integer signedness problems is already hard when only fundamental
types like "int" and "unsigned" are involved. It gets very hard
when types come into the picture that have platform-dependent
signedness, like "char" and "wint_t". Adding yet another layer
on top, changing both the signedness and the width in a platform-
dependent way, makes auditing yet harder, which IMHO is really
dangerous. Note that while removing the #define, i already found
one bug caused by this excessive complication - in the function
re_putc() in refresh.c. If WIDECHAR was defined, it printed an
Int = wint_t value with %c. Fortunately, that bug only affects
debugging, not production. The fix is contained in the patch.
With WIDECHAR, this doesn't change anything. For the case without
WIDECHAR, i checked that none of the places wants to store values
that might not fit in wint_t.
This only changes internal interfaces; public ones remain unchanged.

christos | PR/18995: David Laight: libedit fixes for posix conformant sh
The posix 'sh' specification defines vi-mode editing quite tightly.
The netbsd libedit code (used by sh to do this) was missing several
features, there were also minor errors in others.
Compare netbsd sh to the definition available from:
http://www.opengroup.org/onlinepubs/007904975/utilities/sh.html
In particular the following were not supported:
U - undo all changes to line
| - goto column
Y - yank to end of line
y - yank
# - comment out current line
@ - take input from shell alias [1]
G - goto numbered line in history buffer
v - edit history line with vi
_ - append word from last input line
. - redo last command
Other minor changes have also been made.
[1] This needs the shell to define an appropriate routine to
return the text of the alias. There is no requirement that
such a function exist.
