running it on “~/.” (must be a directory) in a global readonly variable
• if readlink fails, use some more or less sane values (no idea what csh(1)
does in these cases, maybe some feedback here?)
• optimise, while here
• dirs, pushd, popd like ports/shells/csh (Berkeley C shell)
• precmd, chpwd like ports/shells/zsh (Z shell)
and implement keeping ${DIRSTACK[0]} up to date via chpwd()
instead of doing it on entry of pushd and dirs (so that it
can be used directly)
this is slow compared to earlier, but people seem to want it
we already do not 'function\nfoo\n{' for shell, like style(9) requires for
C programming, but 'function foo\n{' instead. however, we could treat the
function keyword as indentation initialiser and use 'function foo {' (on a
line for itself) – it looks different, unusual, but acceptable, and mksh's
own output (dumping with the “functions” builtin) does that too (although,
its indentation style sucks, but is legible enough)
place most stuff from /etc/profile in /etc/skel/.mkshrc; admins must make
sure to copy this file to users' homes on upgrade (benefit: non-login but
interactive shells also get all the goodies); fix some quoting; simplify,
reformat, change comments
• from an mksh point of view:
slight internal changes in dot.mkshrc; external commands are now prefixed
with “ulimit -c 0”; $TERM is defined; improvement in determining the host
name (e.g. on Debian if a FQDN is not given); declare locals as such both
in $PS1 and outside; remove superfluous quoting, quote properly; simplify
hd alias, add rot13 alias; place RCS ID at the bottom
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version
¹) side effect from creating API-correct cstrchr, cstrstr, etc.
uses goto so it must be better ☻
tested on mirbsd-current via both Makefile and Build.sh
of a pipeline is executed in a subshell' trick, don't use co-process
(because that's verbose twice in an interactive shell profile), move
the noglob block into the while and rid the redundant +o and local.
* sync dot.mkshrc sample with FreeWRT r383
* add some stuff from src/etc/profile and contrib/samples/etc_profile
* sync the latter two with reality and shorten
* teach the user in the mksh installation instructions to install the sample
NB: the sample is also covered by the MirOS licence
