1 /*@ S-nail - a mail user agent derived from Berkeley Mail.
2 *@ Account, macro and variable handling.
3 *@ HOWTO add a new non-dynamic boolean or value option:
4 *@ - add an entry to nail.h:enum okeys
5 *@ - run mk-okey-map.pl
6 *@ - update the manual!
7 *@ TODO . should be recursive environment based.
8 *@ TODO Otherwise, the `localopts' should be an attribute of the lex_input.c
9 *@ TODO command context, so that it belongs to the execution context
10 *@ TODO we are running in, instead of being global data. See, e.g.,
11 *@ TODO the a_LEX_SLICE comment in lex_input.c.
12 *@ TODO . undefining and overwriting a macro should always be possible:
13 *@ TODO simply place the thing in a delete-later list and replace the
14 *@ TODO accessible entry! (instant delete if on top recursion level.)
15 *@ TODO . Likewise, overwriting an existing should be like delete+create
16 *@ TODO . once we can have non-fatal !0 returns for commands, we should
17 *@ TODO return error if "(environ)? unset" goes for non-existent.
