beep and don't do anything else. This mimics the behavor of ^D outside in
normal terminal mode. (^D in vi scrolls forwards and as such isn't
appropriate to emulation)
- c_gets() was usually returning a length, but sometimes
one of the CC_xxx values (which are small +ve integers)!
- fixed c_gets() by putting a ' ' under the cursor.
From David Laight.
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.
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
Ensure that the <readline/history.h> link to <readline/readline.h> is
installed too for 'make includes'. Also, avoid creating obj dir.
This is finally real fix for lib/12929.
XXX Is this right?
them there.
readline.h of libedit had to move to subdirectory 'readline', due to the way
BSD makefiles work; this is better than potentially fragile Makefile hacks
* pad entries shorter than 'max' by spaces correctly
* fix off-by-one error which caused extra newline to be printed
if the list fit exactly to a screen
* fix typo in _rl_qsort_string_compare, which caused the list to not
be sorted after all
implement displaying of possible completions, add hook to display the list
on second rl_complete() invocation in row (typically, double <TAB>)
This addresses the completion part of lib/11581 by Richard Earnshaw.
hardcoded value of 4.
A_K_NKEYS is currently 6 and this mismatch was stomping memory when
initializing the keys. (specifically gdb lost the exec file name if it was
a long path name).
properly together. xxgdb communicates with a gdb running on a pty
that it sets to -echo,-onlcr prior to forking the gdb process.
GNU readline preserves the -echo setting while libedit was undoing it
(setting the tty to a sane state and totally confusing xxgdb's parser).
this diff simply disables libedit if both readline emulation and
"stty -echo" are used/set. that is enough to make xxgdb work once
again, but (XXX) this is not how GNU readline handles stty -echo (it
does not echo anything, but editing commands like ^A,^K, etc.
still work), so the readline emulation isn't perfect.

This makes gdb \ escaping work reliably and fixes lib/9511 by Assar Westerlund.
I wrote for tcsh(1) three years ago.
- implement EL_RPROMPT, which allows a setting/getting of a function which
returns a string to be used as the right-side prompt.
- improve HISTORY and AUTHORS sections in editline(3).
- bump shlib minor version for EL_RPROMPT.
XXX: due to an implementation issue, the rprompt has a 1 space gap before the
edge of the logical screen. editline's logical screen is 1 space less
than the full screen width, so there's a 2 space gap between the rprompt
and the right end of the physical screen. i'm not concerned about this.
re_refresh(): cast the character passed to re_addc() to unsigned char,
so we don't end up calling isprint() with negative value
when chars are signed and character value is >= 128
- don't reopen fp if it was successfully opened in a previous check
- use strlcpy()/strlcat() instead of snprintf() to build a pathname,
since the former are more portable to other systems than the latter
* whitespace fascism
plus a few bogons noted along the way:
1) Set EDIT_DISABLED if terminal type is emacs.
2) fix bug in NO_TTY mode which caused it to not notice CR or LF
3) implement EDIT_DISABLED within libedit to be somewhat like NO_TTY,
except that a prompt is printed first.
* implement el_get(EditLine *, int op, void *result), which does the
inverse of el_set()
* add EL_EDITMODE operation to el_set and el_get; if non zero editing
is enabled (the default).
* add "edit on | off" editrc command, which modifies EL_EDITMODE.
users can now add '*:edit off' in ~/.editrc as an advisory to
disable editing.
NOTE: at this time EL_EDITMODE is just an indication of the
state of the 'edit' command. It's up to the application to check
this after el_source() or el_parse() to determine if editing is still
required.
of the user's namespace. We need to do this because the readline
emulation functions call term_beep(), but readline isn't built using
the same (funky) namespace-protection method as the rest of libedit (it's
included like a normal library object).
Without this (fairly disgusting) hack, any program linked against
libedit will fail to link with an unresolved reference to term_beep()
if using an Elf toolchain (e.g. on the Alpha).
XXX Why this doesn't happen with NetBSD's a.out toolchain is a mystery
XXX to me, and I'm not sure I really want to know (given that a.out
XXX _should_ break the same way as Elf does in this case).
anywhere else.
- for now, override WARNS=0 in librpcsvc and libwrap, until they're
cleaned up
- rcsid police
lib is now clean (except for librpcsvc and libwrap) on the i386, and
this should motivate the other ports to fix any other minor problems
that their compilers pick up that the i386 version doesn't.
