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.
The difference was mostly harmless in the common case "(see manref(foo)(42))",
which expanded to "(see man page foo(42))" under ztexi.yo, but in other
contexts the ztexi.yo expansion was was nonsensical; for example:
"the BSD manref(echo)(1) command"
"the string returned by the manref(getlogin)(3) system call"
"advisory file locking (via the manref(fcntl)(2) system call)"
"this is the exact opposite from manref(ls)(1),"
While there, copyedit some uses of manref()().
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.
Works for both normal and typeset case, also var+=...
Still to do: allow to be mixed with straight array assignment,
improve typeset -p, implement [key]+=value.
If the child's resisdent set size in megabytes exceeds this, print
out the resource (TIMEFMT) string. Document you need to add memory
usage to this by hand.
Combination of 12 commits from interrupt_abort branch.
Basic strategy is to introduce bits to errflag and to set and
reset them separately.
Remove interrupt status on return to main keymap.
Turn off ERRFLAG_INT for always block.
Restore bit thereafter: we probably need a new variable in order
to allow user interrupts to be reset in the always block.
Add TRY_BLOCK_INTERRUPT
This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too.
Ensure propagation of SIGINT from exited job.
If received by foreground job, shell uses ERRFLAG_INT, not
ERRFLAG_ERROR, to set the new state.
Reset errflag before precmd()
Add always block in _main_completion to fix ZLS_COLORS
Ensures we get the right state of $ZLS_COLORS at the end of _main_complete
even if there's an interrupt. However, the "right state" is a bit messy
as it depends on styles.
