Peter Stephenson d6b027c3c1 51350: ${(S)...//#%...} didn't match the whole string 2023-02-06 14:16:17 +00:00
Peter Stephenson 76d095df9d 51306: error message in ${unset?error} should be expanded 2023-02-02 10:12:17 +00:00
Oliver Kiddle 667ead3a64 51258, 51272: refactor handling of terminal attributes, removing OFF flags in zattr 2023-01-10 20:53:17 +01:00
Oliver Kiddle a73c705b0c 51212: remove STOUC() macro 
This served as a workaround for ancient compilers where casts to
unsigned char were broken.

Jun-ichi Takimoto 8154ddc62d 49853 + 49882/49883: make "${arr[*]:off}" compatible with ksh/bash 2022-03-29 11:09:36 +09:00
Jun-ichi Takimoto 9b3a292410 49166: fix coredump in ${name:offset:length} with ill-formatted length 2021-07-19 09:13:03 +09:00

Bart Schaefer 82ff9f24f1 48560: add TYPESET_TO_UNSET option to remove initialization of parameters 
Changes typeset such that ${newparam-notset} yields "notset" and
"typeset -p newparam" does not show an assignment to the parameter.  This
is similar to the default behavior of bash and ksh, with minor differences
in typeset output.

Also add tests for some POSIX incompatibilities plus minor changes for test
harness robustness.

Daniel Shahaf 4ba9008ec7 48379: Make the parameter expansion subscript flags parse error message, "error in flags", identify the location of the parse error. 2021-04-08 02:19:39 +00:00

Peter Stephenson 7865486994 46100: Fix =subst before =(subst) 
This occurs with SH file expansion ordering.

Add test.

Peter Stephenson b8dc5a7f6d 44435: Handling digita arguments for :h and :t. 
Pick number of leading or trailing path components to substitute.
Active in history, brace parameters, glob qualifiers.

Add tests for all three environments.

Bart Schaefer c19a0927e1 43921: ${\var} should be an error 2018-12-21 11:41:07 -08:00
Peter Stephenson 50f8fa972c 43837 plus test from Daniel: Empty string in nested subst. 
Skip Nularg or there is a bogus character at the start.
 2018-11-21 10:10:03 +00:00
Peter Stephenson f99f7dca75 43616: Various parameter setting and display fixes. 
Mostly to do with typeset -p and tied variables and their interaction.

Some general tied variable fixes.

Jun-ichi Takimoto baedd62f0d 43219 (except term{cap,info}.c): fix several memory leaks 2018-07-31 22:15:58 +09:00
Joey Pabalinas 110b13e109 42313: avoid null-pointer deref when using ${(PA)...} on an empty array result 2018-01-23 22:28:08 -08:00
Peter Stephenson b3fa5c528c 41877: Separate out SH_FILE_EXPANSION loop from parameter substitution. 
Parameter substitution can add nodes that need to be rescanned by
it, but not by file expansion, so the two don't play well together.
 2017-10-13 18:17:09 +01:00
Barton E. Schaefer b84d69cf52 41828, 41830: skip SHFILEEXPANSION for new nodes added by stringsubst() in prefork() 2017-10-08 18:08:09 -07:00
Peter Stephenson 728f2adfc8 Add typeset -p1, like typeset -p with newlines 2017-10-01 17:53:56 +01:00
Peter Stephenson 6230e82d44 41764 (test tweaked): allow [key]+=value when modifying arrays 2017-09-27 09:41:50 +01:00
Peter Stephenson 7d4b41b52a 41747: Don't create hash entry if just checking existence. 
Pass a flag in indicating this case.
 2017-09-25 20:03:05 +01:00
Peter Stephenson 85b0dd7133 Updates for ksh array element syntax. 
Move detection of key/value pairs down into prefork().

Detect normal array assignment and [key]=val array assignemnt
separately.  Mark key / value pairs with Marker and pass up flag.  Deal
with marked triads specially later on.

Peter Stephenson e44600d9aa 41661: Need to remove tokens before using bufferwords() for (z) 2017-09-10 18:01:39 +01:00
Barton E. Schaefer 207263a61e 40929 (replaces 40598): paramsubst() should always return scalar when PREFORK_SINGLE was passed in from prefork() 
Previous commit (74fe4d09) consumed too much of the input linked list,
leading to later expansions being skipped.  This commit converts from
array to string sooner, but may thereby alter rc_expand_param and array
element uniqueness behavior.

Barton E. Schaefer 420fc41b7c 40832: fix $x:P when PWD=/ 2017-03-11 14:40:12 -08:00
Peter Stephenson f3f8537cfa 40760: Always tokenize unquoted - to Dash. 
This fixes use of pattern match character ranges in unusual contexts.

Attempt to detect a tokenized - in cases where we don't care.
 2017-03-07 10:43:58 +00:00
Barton E. Schaefer 4b8db48c6b 40640: the (A) parameter flag forces array result even if assignment syntax is not used 2017-02-25 15:56:50 -08:00
Barton E. Schaefer 74fe4d0950 40598: paramsubst() should always return scalar when PREFORK_SINGLE was passed 2017-02-20 13:26:49 -08:00
Barton E. Schaefer b3c186028e 40593: SHWORDSPLIT + unset IFS should cause default splitting of $@ 2017-02-20 13:26:49 -08:00
Peter Stephenson 4d6097657c 40375: autoload with explicit path mustn't trash already loaded function. 
Also remove unnecessary dupstring() on already duplicated string
when expanding =cmd.
 2017-01-18 09:57:55 +00:00
Barton E. Schaefer c4dba4f2e6 users/22319: ${ary1:^ary2} should not change isarr state of expansion of ary1 
Unless ary1 is made from a scalar, semantics of (@) in double quotes is lost.
 2017-01-03 14:44:12 -08:00
Barton E. Schaefer a409adc33b 40071: change Dash back to "-" before evaluating named directory expansions 2016-12-03 15:00:46 -08:00
Barton E. Schaefer 3ba86f4db4 40034: clear badcshglob when ignoring errors 2016-11-29 12:35:57 -08:00
Eitan Adler 110ffae9fe 40035: Cosmetic fixes for comments and documentation. 
Mostly fixes to doubled words.
 2016-11-29 17:13:52 +00:00
Peter Stephenson 921b39ac6b 39949: Special case for "-" in directory names. 
It can be sh-tokenized to Dash to allow for appearing in ranges
after substitution, so needs to be turned back to "-" in that case.
