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.

|

* So what's going on here then? I'm glad you asked. To test
|
|
* whether we should start menu completion, we test whether
|
|
* compstate[insert] has been set to "menu", but only if we found
|
|
* patterns in the code. It's not clear to me from the
|
|
* documentation why the second condition would apply, but sure
|
|
* enough if I remove it the test suite falls over. (Testing
|
|
* comppatmatch at the later point doesn't work because compstate
|
|
* is likely to have been reset by the point we actually insert
|
|
* the completions, after all functions have exited; this is at
|
|
* least part of the problem.) In the present case, we are not
|
|
* doing matching on the code because all the clever stuff has
|
|
* been done over our heads and we've simply between told to
|
|
* insert it. However, we still need to take account of ambiguous
|
|
* completions properly. To do this, we rely on the caller to
|
|
* pass down the same prefix/suffix with the patterns that we
|
|
* would get if we were doing matching, and test those for
|
|
* patterns. This gets us out of the hole apparently without
|
|
* breaking anything. The particular case where this is needed is
|
|
* approximate file completion: this does its own matching but
|
|
* _approximate still sets the prefix to include the pattern.
