If you want to stop using `local -` in rc and use `_s=$(set +o)`, etc., please do so consistently. > set -o noglob > > for line in $(set); do > @@ -241,6 +242,7 @@ list_vars() > ;; > esac > done > + eval $_s > } > > # set_rcvar [var] [defval] [desc] > @@ -292,6 +294,19 @@ set_rcvar_obsolete() > eval ${_var}_obsolete_msg=\"$*\" > } > +# expandpath str > +# Apply pathname expansion to str. > +# > +expandpath() > +{ > + local _s > + > + _s=$(set +o) > + set +o noglob > + echo $1 > + eval $_s > +} > + This is convenient but it should be kept in mind that unlike direct pathname expansion it will not handle correctly pathnames containing spaces. A comment may be appropriate. If you do not want to use `local -`, I would prefer `eval "$_s"` instead of `eval $_s` since not using the quotes requests word splitting which is not needed (although it should not break anything either). -- Jilles Tjoelker
