* Rework environment variable handling to use wordexp, per a suggestion fromEric Andersen2001-03-081-108/+83
| | | | | | | | | 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! -Erik
* remove an unused variableEric Andersen2001-03-071-1/+0

* Fix the memory leak. No really this time.Eric Andersen2001-03-061-7/+9

* Fix func prototypeEric Andersen2001-03-061-0/+1

* Fixed a memory leak in lash. It seems that close_all was calling close()Eric Andersen2001-03-061-1/+1
| | | | | | directly instead of calling mark_closed(), which allowed the memory allocated by mark_open() to never be freed. -Erik
* Close open files before calling builtin_exec(). I've tested thisEric Andersen2001-03-061-0/+1
| | | | | and it fixes bug #1121. -Erik
* This fixes lash so it handles environment variable expansion, regardlessEric Andersen2001-02-201-17/+30
| | | | | | | | 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. -Erik
* Commit Vladimir's latest cmdedit. I modified it slightly to ensureEric Andersen2001-02-161-2/+1
| | | | | | | | 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.
* This patch, put together by Manuel Novoa III, is a merge of workEric Andersen2001-02-141-10/+7
| | | | | | done by Evin Robertson (bug#1105) and work from Manuel to make usage messages occupy less space and simplify how usage messages are displayed.
* Apply a patch from Larry Doolittle to add "-all" and "-none" switchesEric Andersen2001-02-011-1/+1
| | | | | | | 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. -Erik

* Patch from Larry Doolittle to set values to static variables that live in theEric Andersen2001-01-051-2/+15
| | | | | | bss at runtime, since sh.c can call sh.c, which causes these variables to not be set to their defaults as god intended. -Erik
* Fix a segfault by only constructing the prompt when we need to. If we don'tMatt Kraai2001-01-051-2/+2

* Another sh.c patch from Larry Doolittle. This makes redirects work properlyEric Andersen2000-12-211-37/+71
| | | | | | | 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.
* Fix a warning in sh.c. Remove use of getline() in md5sum sinceEric Andersen2000-12-201-1/+4
| | | | nobody else uses it and it is a GNU extension anyways...
* Ok, this is a pretty major update to sh.c. I renamed all the variables andEric Andersen2000-12-181-472/+618
| | | | | | | | | | | | 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. -Erik
