Eric Andersen 15649c11f3 Oops. I left in some debug noise. 2001-05-15 17:28:26 +00:00
Eric Andersen 20a69a77d2 Write set_local_var() and fixup lookup_param() so you can now use 
shell local variables.
 -Erik
 2001-05-15 17:24:44 +00:00
Eric Andersen 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!

Eric Andersen cfa88ecb72 Fix up some silly warnings 2001-05-11 18:08:16 +00:00
Eric Andersen 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.

Eric Andersen 9d94deabd3 Use xgetcwd 2001-05-11 16:36:03 +00:00
Eric Andersen 1a6d39b259 A few more structural updates for job control.

Eric Andersen 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.

Eric Andersen 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.

Eric Andersen 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

Matt Kraai d24f878546 Don't reset parents context when we encounter an terminator. Fixes 
if true; then if true; then true; fi; fi

Eric Andersen e5ffb911e8 If it fails to run a builtin, let it fall through to 
exec the real thing.

Matt Kraai 80abc45182 Move up waitpid error check so that errno isn't clobbered by tcsetpgrp. 2001-05-02 21:48:17 +00:00
Eric Andersen 0fcd447d59 Some more job control updates. It will now sucessfully background 
stuff.  Good luck getting things back into the foreground though...

Matt Kraai 20a3069ec0 Don't treat newline as pipe separator when processing substitutions. 2001-05-02 17:52:49 +00:00
Matt Kraai 9f8caf134f Fix $(...) construction. Noted and patched by Larry Doolittle 
<ldoolitt@recycle.lbl.gov>.  I'm just a patch whore.  :)
 2001-05-02 16:26:12 +00:00
Eric Andersen bafd94f154 First pass at getting job control working. This gets the infrastructure 
in place, but something is still missing/wrong in there.  Testing with
'grep foo &' seems to put _hush_ into the background.  Pondering...

Matt Kraai 1c8a59ab95 Use the current pgrp, not pid, when resetting the foreground process group. 
Fixes bizarre suspension when executing `echo`.

Matt Kraai f162e7d09d Don't segfault if the first word is the empty string. 2001-05-02 14:48:48 +00:00
Eric Andersen e67c3ce327 Another update from Larry: 
Makes hush return code equal to that of the last command executed.
    Fixes the mode where input comes from a file.
 2001-05-02 02:09:36 +00:00
Eric Andersen 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

Eric Andersen aac75e5a78 Some more hush.c updates from Larry Doolittle. 2001-04-30 18:18:45 +00:00
Eric Andersen 088875fec4 Use BUFSIZ for the_command to match size used in cmdedit 2001-04-27 07:49:41 +00:00
Eric Andersen 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.

Eric Andersen 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).

Eric Andersen ed424dbf1d Some patches from Gennady Feldman. Fixed a glob problem such that 
'ls *.h Config.h' works.  Fixed a silly typo with fg/bg process control.
Made cmdedit exit sanely when it cannot read input.

Mark Whitley 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.
