tg 83c2ee87f4 • remove strcasestr.c, use home-grown implementation¹, call it stricmp,
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

tg ad05a2414b * edit.c: when tabcompleting a newline to backslash+newline, this
sequence is eaten before the command is called; cought by <TGEN>
  (Thomas E. Spanjaard) via IRC
  fix is to tabcomplete a newline to singlequote+newline+singlequote
* bump version

tg dd462f00d3 repair 'bind' builtin with no args output; damage taken in -r1.80 2007-02-07 02:01:43 +00:00

tg 0c809f3db9 static int (which was const) -> integrated into its only use 2007-01-15 02:11:34 +00:00
tg 29b62b186d okay, this didn't work out; changing window sizes when we're
actually within a (the emacs) editing mode does not work at
all, whether forced or not, only if we leave the editing mode
(at end of input); probably due to it saving stuff from e.g.
x_cols into xx_cols, etc.

-> remove SIGWINCH handling(!)
-> TIOCGWINSZ is now executed at end of every input line
-> use 'ESC #' if you direly need to change line size
2007-01-14 01:56:23 +00:00
tg 36e761840e * do *not* check the terminal size after each line processing,
only if we got a SIGWINCH -> interactive use speed-up on the
  slower boxen (slowness courtesy of otto@obsd)
* ^L (redraw line) now (always) checks window size; use this
  instead if required while editing the prompt; changes to the
  variables will still be propagated after the line is entered
2007-01-14 01:09:09 +00:00
tg 87f681b488 * revert some of the const-warning cleanup which must be done
with different means (reads, tricky magical kludgery)
  YES, THIS BREAKS -rHEAD, I KNOW.
* while here, fix spelling
2007-01-12 10:18:22 +00:00
tg 5891915f1b * Scan for __attribute__((...)) in general (the earliest was 2.5,
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
  if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
  scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more
2007-01-12 01:49:29 +00:00
tg 98e9111bbc remove the "set -o sh" option (dummy anyway),
"set +o emacs-usemeta" and "set -o vi-show8" which are always on now,
since we have proper internationalisation (i.e. utf-8) support, and
assume the user either has a 'C' locale and can't enter 8-bit chars,
his terminal is 8bit-transparent, or he has a 'UTF-8' locale.
2006-11-19 20:43:14 +00:00
tg 151d913115 remove all but these __CRAZY=Yes build warnings:
main.c: In function 'main':
 main.c:208: warning: cast discards qualifiers from pointer target type
 main.c:329: warning: cast discards qualifiers from pointer target type

no warnings at autoconf time left either; will take care of these two later
(might revisit changes from this commit), maybe change declararion for the
builtins to have their argv[] be const strings, and go through strict type
and qualifier checking again. this'll further improve stability.

XXX these changes might have introduced (more?) memory leaks,
XXX someone who knows about these tools should verify with
XXX automatic memory usage analysers (valgrind?)

still passes testsuite

tg 56ffbf7e70 hand-sorted ctypes/chtypes upgrade; use table-driven where they make
sense and preprocessored otherwise; unify the logic
saves 144t 1i and lots of cpp(1) time, as well as improves readability
2006-11-10 07:52:04 +00:00
tg feb7dddd44 * use only macros for ctype stuff any more
XXX one of these uses a gcc extension, ok for now tho
* don't include <ctype.h> any more at all
* don't try nl_langinfo in small mode, just check locale

saves 171 .text, 4 .data, 256 .bss, 1 import
2006-11-10 07:18:58 +00:00
tg 35b30679c7 since so many internal things hardcode 'C' locale anyway,
use own is{digit,lower,upper} macros that go via byte ranges

doesn't affect utf-8 hack because these only operate on single bytes anyway
saves 224t
2006-11-10 06:53:27 +00:00
tg b323a22b59 use tolower_() and toupper_() macros (if not available, our quick 'C' ones)
76t 8d 2i
2006-11-10 06:45:28 +00:00
tg ca2b1d88ca kill two others, saves 55t 8d 2i 2006-11-10 06:40:05 +00:00
tg d5e4c261db simplify. and, a few byte compares are cheaper than a structure
copy and a structure compare
gain: 103t 4d 1i
loss: had to move some code even though no diff (cvs issue)
2006-11-10 04:31:04 +00:00
tg f8e7fdbb71 use qsort(3) instead of rolling our own
saves 284 in .text, no added import since we already use qsort(3) once

tg f1e29cb1a1 use NELEM 2006-11-10 01:24:38 +00:00
tg 273ca89019 * check.t: add new regression test "typeset-padding-1" according to TFM
* edit.c: remove debug stuff again; next time better use shl.c functions ;)
* sh.h: add format attributes to a few shf functions
* histrap.c, var.c: fix format string mistakes
* main.c, sh.h: error_prefix and warningf take bool not int
* misc.c: make chvt() stuff use shf_* functions
* misc.c: rewrite the TIOCSTTY stuff to be better integrated in mksh,
  since it originally was an external patch
* misc.c: chvt() no longer fails if e.g. chown fails due to e.g. R/O / fs
* var.c: fix typeset padding for right-justified zero-filled

tg 36ac8dc0f7 get rid of the need of strlcat() altogether (only one use was left) 2006-11-09 15:02:31 +00:00
tg 39057dd592 add the new function utf_ptradj() which does the same as utf_widthadj()
except it doesn't return a value and is much cheaper (no internal con-
version to UCS-2, just range checking on the multibytes)
2006-11-09 00:39:27 +00:00
tg fb9c6e30bb fix another warning

tg b03ed7b315 * catch limit off in x_redraw (bytes vs chars vs curpos)
XXX should probably be screenpos, might need to use x_size* here
  XXX this seems to be the tab bug I noticed which we inherited from obsd
* catch backspace if x_col == 0 (XXX better)

tg 4fac7ec24b * remove redundancy
* integrate compat.h, version.h into sh.h (dependency trick didn't work anyway)
* mention #ksh in mksh(1) since the founder (twkm) said it's on topic too
  (don't remove mention of #mksh despite it's usually empty because of control)
2006-08-22 22:49:38 +00:00
tg 4661992d5b remove the 'stuff' functionality altogether,
ksh93 doesn't have it, and I don't know, nor
do I care about what "the BRL ^T mini-systat
feature" is.
2006-08-08 20:17:22 +00:00
tg 5176249248 * bind ^T to transpose-chars as documented in the manual page,
not to stuff, even if TIOCSTI is available
* it's transpose-chars not transpose

bug spotted by hondza who wondered that on ^T the line repeats itself forever
