This is one of two mksh variants; the other uses a tmpfile:
alias doch='sudo mksh -c "${ fc -ln -1;}"'
Both quote correctly, unlike the above.
Maybe use $MKSH instead? (Quoted or unquoted? Hm. Probably quoted.)
Input on that welcome…
Testsuite:
• add new need-pass: {yes|no} attribute, default yes
• exit with 1 if a need-pass test failed unexpectedly
idea by Kacper Kornet <draenog@pld-linux.org>
• mark utf8bom-2 as need-pass: no
Infrstructure:
• add housekeeping function for making a tty raw
• switch functions with unused results to void
• struct op: u.charflag contains last char of ;; in TPAT
• var.c:arraysearch is now a global function
Language:
• add ;& (fall through) and ;| (examine next) delimiters
in addition to ;; (end case) as zsh extensions, because
POSIX standardised on ;& already
• add -A (read into array), -N (read exactly n bytes),
-n (read up to n bytes), -t (timeout) flags for read
from ksh93
• allow read -N -1 or -n -1 to slurp the entire input
• add -a (read into array the input characters) extension
specific to mksh to read, idea by David Korn
• add -e (exit with error if PWD was not set correctly
after a physical cd) to cd builtin, mandated by next
POSIX, and change error codes accordingly
Rewrites:
• full rewrite of read builtin and its manpage section
• add regression tetss for most of the new functionality
• duplicate hexdump demo tests for use of read -a
• use read -raN-1 in dot.mkshrc to get NUL safe base64,
DJB cdb hash and Jenkins one-at-a-time hash functions
add most of the mksh wtf edition dot.mkshrc patch, some commented
out; optimise some other cases (e.g. don't reset MKSH if set, don't
export already exported variables, etc.)
• ensure unsigned arithmetics is used in the cdb hash
• make the hash functions print their result again
• now we can use the Lb64{en,de}code trick of using stdin if "$*"==""
• optimise the one-at-a-time code for shell
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
strip it, but that might have other problems, better is to use realpath(2),
e.g. via readlink(1), for normalisation, or have the sysop fix it)
XXX make realpath a builtin?
* initialise the integers PPID, OPTIND, RANDOM, SECONDS, and TMOUT to base-10
* bring back PGRP as base-10 integer to the process group via getpgrp(2)
* initialise USER_ID as base-10 integer to the effective user id as retrieved
from geteuid(2) = $(id -u)
* use $USER_ID in dot.mkshrc instead of spawning an id(1) process
-> dot.mkshrc,v 1.34 now requires mksh R34
* convert more int to bool where appropriate
* remove dead code - getpgrp(2) cannot fail
* sync manual page to reality
* bump to mksh R34(beta) - feature freeze
XXX check if our_pgrp in jobs.c is still really needed, the setpgid call
XXX probably just makes us our own pgrp leader, and we might have to use
XXX and update kshpgrp accordingly - need feedback/help here but I think
XXX this simplification should be possible if I grok the code correctly.
etc/profile:
* adjust to $USER_ID changes in mksh (speed-up here, too)
mksh.hts:
* sync changelog
‣ now, a “ksh93” just requires ‘function precmd { :; }; set -o emacs’
afterwards to get rid of the annoying error messages
‣ I could lose that with the following idiom:
- PS1='$(precmd)…
+ PS1='$(typeset -i e=$?; typeset -f precmd >&- && { (return $e); precmd })…
but it didn’t seem worthwhile to me
• remove explicit licence blah, normal ./copyright applies
