tg 5f8075fc82 introduce a tobool(cond) abstraction¹ and switch bool to char if !stdbool.h 
① currently: ((cond) ? true : false) but (!!(cond)) and casting to bool,
  the latter only if stdbool.h, would also work – which performs best on
  (and across) all supported systems?

tg 009d4c7b75 drop more currently unused 2011-03-07 20:09:34 +00:00
tg 2075dd23b2 drop unused 2011-03-07 20:08:48 +00:00
tg bfe34ba110 reduce data size by 320 bytes by packing struct lex_state tighter 
and reducing amount of them allocated in each “pack” from 31 to 7
since $(…) is recursive anyway (I tried hard to need even only 5)
 2011-03-07 20:07:52 +00:00
tg 1f392ab09b • more fixes (some regression, some new) 
• more testcases, stricter testcases
 2011-03-06 17:08:14 +00:00
tg 469da2e5e4 drop IFS-space-colon-3 because dash is the only shell which passes it, 
but ksh93 passes ifs.sh which I assume is more correct, and mksh and
ksh93 have the same result for this (as do bash2/4, posh; zsh differs)
 2011-03-06 17:06:17 +00:00
tg 7a6fb85db5 another _two_, gosh! 2011-03-06 02:28:59 +00:00
tg 14d8cecc82 plug _another_ %; versus %N output formatting bug 
(apparently, nobody noticed them because everyone outputted to files,
not to strings, and this logic differs for those)
 2011-03-06 02:14:09 +00:00
tg c995f7ca98 I thought of making COMSUB pass a pointer to the struct op *t->left around 
instead, but the parser for the so-called “backticks” (U+0060) still emits
plaintext COMSUB wdstrings, and the evaluation code emits plaintext if the
code is not run (‘-n’ option), so it’s not worth the effort and memory ma-
nagement issues, even though it _would_ optimise the most common case…

Bump version numbers, sync regression tests; add one testcase from the old
webpages too. Sync manpage, this now works, but keep the workaround in, as
“portability issue” with slightly changed wording.

Also, /bin/sleep must be used in one manpage example if sleep is built in.

tg 25905b91a7 the long-awaited recursive parser for COMSUB $(…) expressions 
fixes RedHat BZ#496791

tg e93daee5f4 dump TCASE as "case $foo in (1) blah ;; esac" not "… (1); blah …" 2011-03-06 00:52:02 +00:00
tg f3dbbe3f0c split malloc_os and friends further into 
• functions called by mksh’s grouping memory allocator
• functions called by mksh code itself

the latter may be changed to call the internal grouping allocator,
if a porter so desires (but if this were recommended, the code in
question would already do so, so…)
 2011-03-05 21:48:09 +00:00
tg 0b6afea352 introduce macros for malloc, realloc, free to hide them from mksh 
no code may henceforth use memory (de-)allocation functions directly
use these macros, porters can change them for abstraction
 2011-03-05 21:43:18 +00:00
tg ad2fd952e4 nvm, got it 2011-02-27 19:41:17 +00:00
tg 3019066e60 no idea why MiNT has this… issue… 2011-02-27 19:31:34 +00:00
tg 6a941a3c39 fix UWIN: don’t close fd #3 (also, int→bool) 2011-02-27 19:29:32 +00:00
tg e0c4ad7fa9 port to FreeMiNT: add OS uname and flags; 2>&- is evil™; $UNIXMODE must be preserved; unlink(2) is weird 2011-02-27 19:29:20 +00:00
tg 816bf86710 MKSH_NOPROSPECTOFWORK has no co-processes. at all. 2011-02-19 21:39:14 +00:00
tg 0b57abd4d3 • add -u option (POSIX: unbuffered ⇒ nop) to the built-in cat 
• PIPESTATUS now supported (like bash 2) whose last member
  may actually differ from $? since the latter may not be the
  result of a pipeline partial command
• add regression tests, documentation, etc.
 2011-02-18 22:26:13 +00:00
tg 36d41ed9ee * plug a regression introduced as a pasto (think, mira!) 
* add selftest-direct-builtin-call regression test, while here
 2011-02-13 21:13:08 +00:00
tg a796512040 • more comment and int→bool cleanup, add and improve some comments 
• in interactive mode, always look up {LC_{ALL,CTYPE},LANG} environment
  variables if setlocale/nl_langinfo(CODESET) doesn’t suffice
• add the ability to call any builtin (some don't make sense or wouldn't
  work) directly by analysing argv[0]
• for direct builtin calls, the {LC_{ALL,CTYPE},LANG} environment
  variables determine utf8-mode, even if MKSH_ASSUME_UTF8 was set
• when called as builtin, echo behaves POSIXish
• add domainname as alias for true on MirBSD only, to be able to link it
• sync mksh Makefiles with Build.sh output
• adjust manpage wrt release plans
• link some things to mksh now that we have callable builtins:
  bin/echo bin/kill bin/pwd bin/sleep (exact matches)
  bin/test bin/[ (were scripts before)
  bin/domainname=usr/bin/true usr/bin/false (move to /bin/ now)
• drop linked utilities and, except for echo and kill, their manpages
• adjust instbin and link a few more there as well

tg 8b73363c20 query for select(2) in preparation of sleep and read-with-timeout builtins; ualarm(3) and friends are too awkward to use so we ifdef these builtins on select support ☹ 2011-02-09 19:32:26 +00:00

tg d158038191 Limit history file size to 1 GiB for sanity (especially considering struct stat.sb_size is sometimes unsigned, sometimes signed, and sometimes larger than long, ugh…) 2011-02-09 15:08:01 +00:00
tg 5161342b9b fix warning about signed vs. unsigned comparision and potential truncation error 2011-02-09 13:08:27 +00:00
tg 4e0f597b5d fix prev-hist-word again, thanks Jörg-Volker Peetz 2011-02-09 13:08:18 +00:00
tg d4658a569e refactor code to be able to track whether we have a parameter substitution 
or a “proper” glob expansion; if there’s a dollar, but not a glob, refrain
from appending a space later (LP: #710539)
 2011-02-03 15:57:52 +00:00
tg 1c4aab3a3e when setting a UTF-8 locale, also set -o utf8-mode 
since we might start on e.g. GNU/Linux with a system-wide C locale

tg 45d99b9ec9 Scan for existence of <sys/file.h> which is not ubiquitous; allows 
klibc-mksh (despite no hope to get a signal of a job) persistent history

tg 30d8e3934d SUSv4 says trap foo UNKNOWN is not a syntax error, merely exit ≠0. 
Inspired by 673dab8698b0399c967216c02262eaf95361a75c.
 2011-01-30 01:36:00 +00:00
tg bdfcdc56c8 introduce MKSH_NOPROSPECTOFWORK which is like pdksh’s JOB_SIGS in reverse, like MKSH_UNEMPLOYED is pdksh’s JOBS in reverse; allows mksh to work (hah! no pun intended…) with klibc (and possibly, Syllable Desktop and Plan 9) for now, until they fix their bugs 2011-01-30 01:35:35 +00:00

tg 230f59d064 New functionality: assign here document to string variable directly, 
without cat and temp files. Hacked in Lëtzebuerg ☺

This was the third try. Where to put this was not palpable… same for =(…)
 2011-01-09 21:57:29 +00:00
tg b4948e430f this is a bashism but might be from ksh93 IIRC… still dead ugly as hell! 2010-12-19 20:00:56 +00:00

optimise libc wcwidth(3) implementation taken from mksh and sync these

tg beba20ea56 since dot.mkshrc is sourced by interactive shells anyway, and exporting 
PS1 may hurt other shells, do not export it any more
