/* FIXME: a big list of fixes that must occur. |
|
* |
|
* (1) Distinction not between ROFF_TEXT and ROFF_LAYOUT, but instead |
|
* ROFF_ATOM and ROFF_NODE, which designate line spacing. If |
|
* ROFF_ATOM, we need not remember any state. |
|
* |
|
* (2) Have a maybe-NULL list of possible subsequent children for each |
|
* node. Bl, e.g., can only have It children (roffparse). |
|
* |
|
* (3) Have a maybe-NULL list of possible parents for each node. It, |
|
* e.g., can only have Bl as a parent (roffparse). |
|
* |
|
* (N.B. If (2) were complete, (3) wouldn't be necessary.) |
|
* |
|
* (4) Scope rules. If Pp exists, it closes the scope out from the |
|
* previous Pp (if it exists). Same with Sh and Ss. If El exists, |
|
* it closes out Bl and interim It. |
|
* |
|
* (5) Nesting. Sh cannot be any descendant of Sh. Bl, however, can be |
|
* nested within an It. |
|
* |
|
* Once that's done, we're golden. |
