* Another hush update from Larry:Eric Andersen2001-06-071-14/+16
| | | | | | | Fixes the interaction between if/then/else/fi syntax and variables. I planned to do it right from the beginning, but my implementation was buggy. Also adds the relevant test cases. Also adds some old Matt Kraai variable test cases that got left out somehow.

* It turns out job control in both hush and lash was broken by theEric Andersen2001-05-171-10/+22
| | | | | | signal handling in cmdedit.c. Disabling it makes the shells behave themselves again. hush isn't quite there, but is getting close... -Erik
* Move init of a bunch of globals into main so we are at leastEric Andersen2001-05-161-7/+16

* Write set_local_var() and fixup lookup_param() so you can now useEric Andersen2001-05-151-4/+101

* This patch covers one big part of variable handling.Eric Andersen2001-05-151-5/+49
| | | | | | | | | | | | | | | $ a=b foo should be handled correctly. $ a=b is parsed OK, but the actual variable setting is not yet written. Except for some weird exceptions related to quoting rules, this code passes (matches ash behavior) all the tests I threw at it. If someone now writes set_local_var(), and updates lookup_param() to match, we can claim success! - Larry
* Fix up some silly warningsEric Andersen2001-05-111-3/+3

* Fix a segfault in lash, hush, and cmdedit. Each of these usedEric Andersen2001-05-111-0/+6

* Fix a stupid segfault caused by dereferencing a NULL ptr.Eric Andersen2001-05-081-0/+2

* This patch from Evin Robertson <nitfol@my-deja.com> fixes export so it works.Eric Andersen2001-05-071-1/+4
| | | | | This way leaks memory, but oh well. We will probably fix that when we get around to doing local variables.
* More hush updates from Larry:Eric Andersen2001-05-071-19/+54
| | | | | | | Update some comments. Generate partial placeholders for the missing builtins. Write builtin_umask. Properly treat exec without arguments as a means to open/close files within the running script. Implement "4<&-" that encodes for file descriptor closure.
* Larry's variant on Evin Robertson's fix to what I messed upEric Andersen2001-05-041-1/+1
| | | | | | trying to make job control work. This fix makes it so that hush doesn't error out when init hasn't set up job control, as in when init=/bin/sh

* Move up waitpid error check so that errno isn't clobbered by tcsetpgrp.Matt Kraai2001-05-021-3/+3

* Some more job control updates. It will now sucessfully backgroundEric Andersen2001-05-021-46/+74

* Don't treat newline as pipe separator when processing substitutions.Matt Kraai2001-05-021-1/+4
|
* Fix $(...) construction. Noted and patched by Larry DoolittleMatt Kraai2001-05-021-0/+1

* First pass at getting job control working. This gets the infrastructureEric Andersen2001-05-021-13/+142

* Use the current pgrp, not pid, when resetting the foreground process group.Matt Kraai2001-05-021-1/+1
| | | | Fixes bizarre suspension when executing `echo`.
* Don't segfault if the first word is the empty string.Matt Kraai2001-05-021-2/+4
|
* Another update from Larry:Eric Andersen2001-05-021-17/+19
| | | | | Makes hush return code equal to that of the last command executed. Fixes the mode where input comes from a file.
* Another hush update from Larry:Eric Andersen2001-05-011-5/+13
| | | | | | | | | | | | | | Minor improvements. Something is still broken with running scripts via "hush filename". All the following are now handled acceptably (matches ash, not bash). if true; then echo foo1; fi if true; then echo foo2; fi if true; false; then echo bar; else echo foo3; fi if true || false; then echo foo4; fi - Larry
* Some more hush.c updates from Larry Doolittle.Eric Andersen2001-04-301-13/+46
