e44600d9aa 41661: Need to remove tokens before using bufferwords() for (z) 2017-09-10 18:01:39 +01:00

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.

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.

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.

07c8fbe596 34943: Fixes for "command" with multiple options.

system path.

a4b8ee13be zsh-users/21903: Fix ${...?...} in interactive shell. 
On failure should abort back to top level, but we reset the error
flag around commands.  Add a hard error flag that's only reset at top level.

c6c9f5daf2 34322: bug with interface to parsestr() etc. 
Was showing up in places like ${(e)...} where command substitution
could reallocate the token string, but actually there was never any
guarantee that the lexer wouldn't do that, so this was always
a bit iffy.

d067ebcacd 33876: etc.: Separate errors and keyboards interrupts 
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.
