15649c11f3 Oops. I left in some debug noise. 2001-05-15 17:28:26 +00:00

20a69a77d2 Write set_local_var() and fixup lookup_param() so you can now use 
shell local variables.

78a7c99f7f This patch covers one big part of variable handling. 
$ 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!

5f265b755a Fix a segfault in lash, hush, and cmdedit. Each of these used 
xgetcwd, but did not check the return for a NULL, and then continued
to call strlen on the NULL when the cwd had been removed from under it.

45e92ba2ce This patch from Evin Robertson <nitfol@my-deja.com> fixes export so it works. 
This way leaks memory, but oh well.  We will probably fix that when we get
around to doing local variables.

83a2ae2184 More hush updates from Larry: 
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.

2dcfba7117 Larry's variant on Evin Robertson's fix to what I messed up 
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

4ed5e37d4b Another hush update from Larry: 
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

af44a0e8f4 An update to hush from Larry: 
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.

25f2703015 This is the initial checkin of Larry Doolittle's hush.c, using his 
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).

f594986b37 - Changed name of BB_FEATURE_SIMPLE_PROMPT to BB_FEATURE_SH_SIMPLE_PROMPT 
- Set BB_FEATURE_SH_STANDALONE_SHELL and BB_FEATURE_SH_APPLETS_ALWAYS_WIN to
   be off by default
 - Set BB_FEATURE_SH_SIMPLE_PROMPT to be on by default
 - Added some more magic to the Olympus section to make all the dependencies
   on the shell, cmdline editing, tab completion and friend work properly.
 - Tidied up the Olympus section with some whitespace. Checked the various
   scrips that parse through there and the extra whitespace shouldn't break
   anything.

ca6045955d Rework environment variable handling to use wordexp, per a suggestion from 
Larry Doolittle a couple of months ago.  This makes the stuff-expansion in lash
be ever so standards compliant.   This change needs testing by everyone, but
appears to be solid enough to let us close bug #1090.

It works for me; however, please test this change!

caeeb36784 This fixes lash so it handles environment variable expansion, regardless 
of where the environment variables are located in an argument.  This allows
things like 'echo foo$1$SHELL' to expand the same way bash would expand it.
Of course, to make this work I introduced a memory leak, and I am too tired
to find a way to fix it.

6faae7deb4 Commit Vladimir's latest cmdedit. I modified it slightly to ensure 
parse_prompt() would be called before cmdedit_init(), since cmdedit_init()
calls cmdedit_setwidth() which uses cmdedit_prmt_len, which is set by
parse_prompt().  Also, added a mod, so very narrow terminals should now wrap
properly...  This is working very nicely for me -- Vladimir has done some
very good work.
