195743f195 Ok, sh.c should be working now. Many thanks to Larry Doolittle
for his timely help -- nearly all of the work in this patch is
his.

32f8c170b0 Remember to delete un-expandable variables, and do a better job of expanding
shell-specific things in case the wordexp implementation is broken (ie. the
stubbed out wordexp in uClibc).

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!

54851d3c65 Fixed a memory leak in lash. It seems that close_all was calling close()
directly instead of calling mark_closed(), which allowed the memory allocated
by mark_open() to never be freed.

5165fbed63 Oops. Since dirent.h depends on BB_FEATURE_SH_TAB_COMPLETION, put it
after busybox.h is included.
2001-02-20 06:42:29 +00:00
Eric Andersen
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.

cbe31dace5 It turns out that DODMALLOC was broken when I reorganized busybox.h
header file usage before the 0.49 release.  To fix it, I had to move
the '#include "busybox.h"' to the end of the list of #include files.

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.

67991cf824 This patch, put together by Manuel Novoa III, is a merge of work

af4ac77d9d Apply a patch from Larry Doolittle to add "-all" and "-none" switches
to multibuild.pl.  I did a little formatting adjustments to make it
_very_ obvious when things stop working.  I also removed the USE_PROCFS
config option -- just do the right thing when USE_DEVPS_PATCH is enabled.

e9f07fb6e8 Another sh.c patch from Larry Doolittle. This makes redirects work properly
with non-forking shell builtins.  Especially helpful for "read".  This patch
also beautifies builtin_fg_bg, clarifies the problems with
run_command_predicate, makes if/then/else support the default, and corrects the
sense of the BB_FEATURE_SH_ENVIRONMENT comment.

Eric Andersen
86349776d0 Ok, this is a pretty major update to sh.c. I renamed all the variables and
function names to conform with the style guide.  I also did a lot of work on
the if-then-alse-fi logic and added prototype (i.e. it segfaults when enabled)
line continuation support.

Furthermore, this patch includes Larry Doolittle's work on restructuring some
of the data structures that represent the job and child_program, allowing
several simplifications and fixing several bugs.

3522eb1ab3 First pass at writing a shell for busybox.
Works fine, full job control support, etc.
No syntax yet (if, then, while, etc).  Handles

TODO: add command editing, add syntax suport.
