tg b330976689 this hack from commitid 1004651F21443013C37 is no longer necessary (thought so) 2016-07-26 22:55:35 +00:00
tg 9dbd643504 implement new evaluate-region editing command (!MKSH_SMALL)
while here, fixup x_redraw refactoring x_clrtoeol, x_pprompt, and x_lastpos

tg 04454868ff the limit parameter to x_redraw was completely bogus, drop it for now 2016-07-26 20:43:14 +00:00
tg 644536732b eek, forgot some conditions 2016-07-26 20:13:40 +00:00
tg 4310e75f75 make tmux hack workable for now (libtermcap is… ugly)
• track $TERM for the types tmux uses /^screen(-.*)?$/
• when tmux is in use (or GNU screen, really), use the, now
  hardcoded, clear-to-EOL string; otherwise, use the old behaviour
• drop unnecessary x_e_rebuildline()

carefully tested to behave no worse than R52b

tg c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)…
• if HAVE_STRING_POOLING is set to 1
• if HAVE_STRING_POOLING is set to 2 and not GCC < 4 is used
• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used

Closes: LP#1580348

tg 8370c0dd4d experimentally use MKSH_CLRTOEOL_STRING instead of lots of spaces followed
by lots of backspaces for many clearing scenarios; requested by tmux user

tg 0fd9337123 implement support for PC scancodes à la CHR$(0)+CHR$(&h48)
superseding an mksh-os2 patch which confirmed this is needed

Reference: my copy of the Schneider EURO PC manual 50032 for
Microsoft® GW-BASIC
2015-07-10 18:41:07 +00:00
tg 5613d6a04a an edchar cannot conceivably be NUL, so set them to the default;
this is confirmed to help fix OS/2 and plugs an uninitialised read
on systems without werase

tg 609b311919 more low-hanging fruits for EBCDIC; notes:
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
  ‣ used in some places
• (c - '0') → ksh_numdig(c)	# may take *x++ argument
• (c - 'A') → ksh_numuc(c)	# may NOT take *x+= argument
  ‣ idem for ksh_numlc(c) and 'a'
  ‣ these need changing for EBCDIC
  ‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹

tg 6b00977053 just another oksh rcsid-only sync (we bind to the Delete key since forever) 2015-04-11 22:09:49 +00:00
tg 532af35304 oksh rcsid sync; we have no set -o csh-history, and the manpage changes are just wrong, so, a nop 2015-03-14 05:17:17 +00:00
tg 61cea6b71b another oksh rcsid-only sync 2015-02-16 15:10:15 +00:00
tg 643bbe7c60 no need for this explicit one, emacsfn.h already defines them 2014-11-25 22:38:53 +00:00
tg 2f52b993a1 • Build.sh: fix NSIG detection for gcc-snapshot
• all: bump version to R50-current; add more comments; whitespace
• all: remove all mkssert(); we’ll do full re-runs of scan-build and,
  hopefully, Coverity Scan/Prevent
• check.t: fix a testcase (sed could exit false, but we don’t care)
• eval.c: fix tilde_ok data type (only unsigned may shl constantly)
• exec.c: fix shebang buf array accesses to always go via uint8_t *

tg 0d9b36daa3 prototype for a static function used before it’s defined
XXX add protos for all static functions (just: hard to find them)
2014-11-19 21:52:16 +00:00
tg 517bd63fe5 rename the “tilde” function; apparently, some system headers define it 2014-11-19 21:49:12 +00:00
tg 0432fc1a87 Get rid of left over NULL elements in x_ftab as NELEM() is used instead.
From Martin Natano. Also get rid of related checks.

tg 89e774fd7e • fix ${12345678901234567890} segfault (OOB access / integer overflow)
‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
  ‣ always use our wcwidth code
  ‣ only use our strlcpy code if none found
• fix a couple of gcc-snapshot and clang/scan-build warnings
• mksh R49~rc1
2014-01-05 21:57:29 +00:00
tg 2f7eec765d merge oksh’s “ctype cleanups” commit
(not much of it applies since we don’t use the OS’ table-based lookup)
2014-01-05 19:11:46 +00:00
tg c4c4fd7365 RCSID-only oksh sync (their whitespace changes don’t apply to us)
note that emacs.c partial peereboom rewrite is *not* merged, and kept that way
2013-11-30 17:33:51 +00:00
tg 7f16464902 slightly optimised and, more importantly, much more consistent (use only
one set of CTRL, UNCTRL, and new ISCTRL macros) C0 and DEL handling; the
optimisation only works for 7-bit ASCII, so those places 8-bit must pass
intact have an added check

also, while here, remove an editor oops (‘;’), oksh rcsid sync (they did
accept I was right wrt. set -e), int → bool, and code merge/cleanup
2013-09-24 20:19:45 +00:00
tg 5eb6995d75 Ypnose discovered a problem with multi-line prompts and SIGWINCH
related to caching some values (downside, pprompt gets back doprint option)
2013-08-16 10:59:03 +00:00
tg bf94b7e2ec fun: when writing this code I feared an off-by-one;
Steffen Daode Nurpmeso stumbled upon it and gave very detailed
instructions on how to reproduce it (thanks!); fix that

also only call x_bs0 if xcp < xep because *xep is undefined
2013-08-14 20:26:19 +00:00
tg c10e5bd237 reduce amount of .bss memory needed; initialise via AEDIT at x_init
or even first run of x_vi
2013-08-10 13:44:33 +00:00
tg 247e20c524 • Completely overhaul prompt length calculation and
prompt display routines; make Emacs and Vi share
  code, permitting reducing of duplication and code
  removal as well as more consistent behaviour; put
  some common code into shared helper functions, too
• New x_adjust() logic (Emacs mode): when determining
  what portion of a line to render use a much more
  sophisticated algorithm and try to fill up ⅔ of the
  total screen width (with line and prompt both) also
  as wished from Steffen Daode Nurpmeso

tg cb93db360d call afreeall(AEDIT) upon close; related to LP#1106116 2013-02-10 17:38:15 +00:00
tg 1da94d6159 pure RCSID sync with oksh, who also added a tabcompletion fix now, with
less code, but, even according to their own comments, not as good as ours
2013-02-10 17:18:49 +00:00
tg b2396677e7 harmonise sys_{sig,err}list ⓐ checks, ⓑ uses, ⓒ _decl values when not needed, ⓓ prototypes; ⓔ “const” is a keyword and thus space-separated from the preceding ‘*’ pointer indicator 2012-12-28 02:28:39 +00:00
tg 0780070d24 add a few assertions for LLVM+Clang 3.2 scan-build; no !DEBUG changes 2012-12-08 18:30:31 +00:00
tg cf807eb83a Add assertions and shuffle code around for LLVM+Clang scan-build. 2012-12-04 01:18:34 +00:00
tg b868c517b7 remove *all* nonnull assertions and other workarounds for clang scan-build
this beast evolved in the last 2½ years, and we’ve had trouble with
some of them earlier
