fix missing bracket by slightly rewriting; from Alan R. S. Bueno
starting with an ‘!’ exclamation mark at the beginning of a com-
mand (PS1 not PS2), shall have the same effect as the predefined
“r” alias, to be compatible with csh and GNU bash’s “!string” to
«Execute last used command starting with string» – documentation
and feature request provided by wbx@ (Waldemar Brodkorb)
and it actually REDUCES code size to allow it as well; mention
in the manpage that it’s merely unportable (and of course exe-
cution time differs); sync clog
• expose “#ifdef MKSH_MIDNIGHTBSD01ASH_COMPAT” just in case they decide to
require it and show it in the ksh version automatically
• sync the use of non-ASCII characters over files (unification)
fix the regression test’s results while here, which have been
broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
bian; track down commits in all files of oksh-mirbsd and mksh
to get correct copyright years per-file, as is BSD custom
${foo:1:2} operates on characters ipv bytes – which means:
‣ set +U: octets
‣ set -U: MirOS OPTU-8 characters
for consistency I also adapted ${#stringname} to deliver the
length in characters ipv bytes; more may follow; for example
I’d like a way to expose the string width.
you can already get the MirOS OPTU-16 of a character in the
WTF-8 (「set -U」) mode with something like
│ typeset -Uui16 -Z7 x=1#${stringname:position:1}
which will correctly use the PUA EF80‥EFFF mapping for octets.
due to this being an incompatible change, bump to R38
also change the unicode-hexdump sample regression test and
add two news for ${x:1:2} and ${#x} checks in A/W mode ☺
which escapes $(…) content does not know if an imbedded ‘#’ is a comment
leader or something else like “16#foo”, “${#bla[*]}”, “${foo#bar}”, &c.
and the comment skip code does not know about nesting beforehand
⇒ document this problem in the place where it already documents that
the current code does not properly handle nested $($(…)) expressions
patches welcome
12:58⎜<gps23:#ksh> someone please tell me why: code=1; if [ "code" -eq 1 ] returns true
13:10⎜<mira|AO:#ksh> hm but I see the problem
13:10⎜<mira|AO:#ksh> code=1; x=code; [ "$x" -eq 1 ]
13:10⎜<mira|AO:#ksh> this is indeed unexpected
13:10⎜«pgas:#ksh» gps23: code=1+1;[ "code" -eq 2 ] && echo true #also works
as of now, we consider
13:13⎜«pgas:#ksh» gps23: when you use -eq there is something like an implicit $(( )) around the
⎜ arguments
13:14⎜«pgas:#ksh» [ code -eq 1 ] is the same as [ $((code)) -eq 1 ]
to be documented.
on Debian Lenny/amd64 (XXX need more verification; this
can be used for 64 bit arithmetics later too)
PPID, PGRP, RANDOM, USER_ID are now unsigned by default
“-sh” if -DMKSH_BINSHREDUCED was passed during compilation, for example
for Debian, but d̲e̲f̲i̲n̲i̲t̲i̲v̲e̲l̲y̲ n̲̲o̲̲t̲̲ for MirBSD™
• split up regression test to force this behaviour
• remove the gunk from our MirBSD™ startup scripts again
• mention arc4random.c changes on website, sync clog, warn packagers
abortion (^G – ^C is SIGINT and doesn’t work like this, but
that’s actually good IMO)
prompted by enquiry about the Emacs editing mode by <smultron:#MidnightBSD>
in a somewhat hackish way, and it’s still quite different from zsh,
but probably closer to a desired functionality
XXX this makes state by abusing 「modified」 and 「xmp」 (“the mark”).
‣ only if !MKSH_SMALL
‣ add appropriate regression test
• if FPOSIX is set, do not close fds > 2 on exec, Debian #499139
• add appropriate regression tests for keeping fds private or not
developers, I understand about 1% of the source code only) yet still
functional (just not en par with the emacs editing mode, but no known
regressions over oksh (in -current) and better functionality than most
other korn shells, according to Yofuh)
and make it fit into mksh’s model (also gives us a couple of things
GNU bash doesn’t have
• add regression tests for all of these
Lukas “smultron” Upton from MidnightBSD spotted a script with /bin/sh
shebang invalidly using “&>” in some Apple backup toolkit, 10x
XXX why fds are limited to one digit?
