* This has scanning/parsing routines, each of which extract a macro and |

* its arguments and parameters, then know how to progress to the next |
* macro. Macros are parsed according as follows: |
* macro. |
* |
|
* ELEMENT: TEXT | epsilon |
|
* BLOCK: HEAD PUNCT BODY PUNCT BLOCK_TAIL PUNCT |
|
* BLOCK_TAIL: TAIL | epsilon |
|
* HEAD: ELEMENT | TEXT | BLOCK | epsilon |
|
* BODY: ELEMENT | TEXT | BLOCK | epsilon |
|
* TAIL: TEXT | epsilon |
|
* PUNCT: TEXT (delimiters) | epsilon |
|
* |
|
* These are arranged into a parse tree, an example of which follows: |
|
* |
|
* ROOT |
|
* BLOCK (.Sh) |
|
* HEAD |
|
* TEXT (`NAME') |
|
* BODY |
|
* ELEMENT (.Nm) |
|
* TEXT (`mdocml') |
|
* ELEMENT (.Nd) |
|
* TEXT (`mdoc macro compiler') |
|
* BLOCK (.Op) |
|
* HEAD |
|
* ELEMENT (.Fl) |
|
* TEXT (`v') |
|
* BLOCK (.Op) |
|
* HEAD |
|
* ELEMENT (.Fl) |
|
* TEXT (`v') |
|
* ELEMENT (.Fl) |
|
* TEXT (`W') |
|
* ELEMENT (.Ns) |
|
* ELEMENT (.Ar) |
|
* TEXT (`err...') |
|
* |
|
* These types are always per-line except for block bodies, which may |
|
* span multiple lines. Macros are assigned a parsing routine, which |
|
* corresponds to the type, in the mdoc_macros table. |
|
* |
|
* Note that types are general: there can be several parsing routines |
|
* corresponding to a single type. The macro_text function, for |
|
* example, parses an ELEMENT type (see the function definition for |
|
* details) that may be interrupted by further macros; the |
|
* macro_constant function, on the other hand, parses an ELEMENT type |
|
* spanning a single line. |
