* 35046: unwind cmdstack when erroring out of lexing a parameter expansion in ↵Barton E. Schaefer2015-05-061-1/+4
| | | | braces
* 34905: no parse error after keyboard interrupt.Peter Stephenson2015-04-171-4/+6
| | | | | | | | Handled generally, though only showing up in special nested cases. Also fix ZLE so it doesn't cancel the interrupt flag when not actually returning from a local keymap.
* 34817: Catch some errors earlier when reading history.Peter Stephenson2015-03-291-0/+2
| | | | | | | | Mostly for the case of an interrupt. Don't try to process words when we know something's gone wrong. Also abort history reading earlier on an interrupt.
* 34781: add implicit space after alias expansion of tokens that form words ↵Barton E. Schaefer2015-03-281-0/+10
| | | | | | without spacing fixes crash when using completion immediately following such an alias
* 34804: refine POSIX_ALIAS change to preserve old behavior of [[ ]] conditionalsBarton E. Schaefer2015-03-281-4/+1

* 34758: fix yet more history / command subst interaction.Peter Stephenson2015-03-221-0/+19
| | | | | | In general we need to wind back over the history text input inside command substitution because there's no level of the input mechanism between history and the lexer.
* 34734: further aliasing adjustments and docBarton E. Schaefer2015-03-181-2/+8
| | | | | | | | restrict token aliasing (34641) to global aliases; tighten up POSIX_ALIASES to better match spec; update Aliasing doc to cover this and clarify older behavior 2015-03-18 Peter Stephenson <p.stephenson@samsung.com> * 34723: configure.ac: turn off fixed site function directory if
* 34651: Avoid core dump if no lexical tokenPeter Stephenson2015-03-051-0/+3

* 34641: make it possible to alias tokensPeter Stephenson2015-03-041-30/+41
|
* 34570: Another nasty command / math substituion thing.Peter Stephenson2015-02-191-19/+45
| | | | | | Mark arithmetic substitutions with tokens to make sure the substitution go knows what to do. Before it was guessing by counting the parentheses at the end.
* 34560: Fix $(( that's actually a multiline cmd subst.Peter Stephenson2015-02-161-0/+4
|
* 34543: Prevent crash on garbage bytes inside $(...)Barton E. Schaefer2015-02-141-2/+4
| | | | | | Garbage input (nul bytes, etc.) can cause the $(...) parser to become confused during look-ahead and attempt to back up the input too far. This commit catches the error but does not fix the underlying cause.
* 34322: bug with interface to parsestr() etc.Peter Stephenson2015-01-181-9/+21
| | | | | | | 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.
* 34319: fix alias expansion in history for command substitutionPeter Stephenson2015-01-181-1/+1

* 32413: turn off history word marking in cmd substPeter Stephenson2015-01-161-0/+2

|
* Rearrange context saving.Peter Stephenson2015-01-091-261/+60
| | | | | | | Variables are now associated with the module that declares them, being initialised and saved/restored there. However, as many variables are used for communication between modules, many of them are set in multiple places, so the assignment is ambiguous.
* Fix command substitutions to parse contents as they are read in.Peter Stephenson2015-01-081-178/+320
| | | | | | | Do this by refactoring misnamed lexsave()/lexrestore() to allow continuity of history and input. Add test.
* 33876: etc.: Separate errors and keyboards interruptsPeter Stephenson2014-12-111-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
