2009-04-10hush: fix a few thinkos in function support; make it work on NOMMU;Denis Vlasenko
functions in child shells now even have $n passed to them! :) (in main shell it still doesn't work)
2009-04-10hush: first stab at function support. argv passing is not coded yet.Denis Vlasenko
Only very rudimentary testing was done. With function support off, code growth is zero, with it on: function old new delta run_list 2158 2339 +181 parse_stream 1929 2044 +115 find_builtin 24 67 +43 find_function - 36 +36 file_get 244 264 +20 pseudo_exec_argv 145 160 +15 free_strings - 7 +7 free_pipe 183 181 -2 done_word 735 728 -7 expand_variables 2227 2204 -23 ------------------------------------------------------------------------------ (add/remove: 2/0 grow/shrink: 5/3 up/down: 417/-32) Total: 385 bytes

2009-04-10hush: tighten up "for" variable name check.Denis Vlasenko
Add TODOs. Disable redir4.right part where we differ from bash. It is not a bug per standards. Add a few tests, one is in hush-bugs section: and_or_and_backgrounding.right. It will likely bite users in real world usage.
2009-04-10hush: fix typo in commentDenis Vlasenko
2009-04-10fix segfault on syntax error code pathDenis Vlasenko
2009-04-10hush: readability improvements.Denis Vlasenko
