* This patch covers one big part of variable handling.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 git-svn-id: svn://busybox.net/trunk/busybox@2644 69ca8d6d-28ef-0310-b511-8ec308f3f277

* More hush updates from Larry: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. git-svn-id: svn://busybox.net/trunk/busybox@2555 69ca8d6d-28ef-0310-b511-8ec308f3f277

* An update to hush from Larry:andersen2001-04-271-94/+20
| | | | | | | | | | | | | | It should recover more smoothly from syntax errors, and it now has a decent guess when the reserved word construct is over (or not) to control execution and prompting. I took out all the redundant standalone test copies of libbb routines, but left in a hook so I can include those for my testing. I'll post that include file on my web site. - Larry git-svn-id: svn://busybox.net/trunk/busybox@2474 69ca8d6d-28ef-0310-b511-8ec308f3f277

| | | | | | | | | | | | | | | April 25, 2001 snapshot, adjusted a bit by me so it has cmdedit support. This checkin also removes sh.c. In the future sh.c will be a symlink to your shell of choice. For now, this symlink will default to pointing to lash.c (as in the past). If you change the symlink to point to hush.c, then thats what you will get. This symlink business is a temporary situation, which will be cleaned up Real Soon Now(tm). -Erik git-svn-id: svn://busybox.net/trunk/busybox@2466 69ca8d6d-28ef-0310-b511-8ec308f3f277
