Uses ffebad (primarily via - ffesta_ffebad_start) to indicate errors in form. In many cases, an invalid - statement form indicates another possible statement needs to be looked at - by ffest. In a few cases, a valid statement form might not completely - determine the nature of the statement, as in REALFUNCTIONA(B), which is - a valid form for either the first statement of a function named A taking - an argument named B or for the declaration of a real array named FUNCTIONA - with an adjustable size of B. A similar (though somewhat easier) choice - must be made for the statement-function-def vs. assignment forms, as in - the case of FOO(A) = A+2.0. - - A given parser consists of one or more state handlers, the first of which - is the initial state, and the last of which (for any given input) returns - control to a final state handler (ffesta_zero or ffesta_two, explained - below). The functions handling the states for a given parser usually have - the same names, differing only in the final number, as in ffestb_foo_ - (handles the initial state), ffestb_foo_1_, ffestb_foo_2_ (handle - subsequent states), although liberties sometimes are taken with the "foo" - part either when keywords are clarified into given statements or are - transferred into other possible areas. (For example, the type-name - states can hop over to _dummy_ functions when the FUNCTION or RECURSIVE - keywords are seen, though this kind of thing is kept to a minimum.) Only - the names without numbers are exported to the rest of ffest; the others - are local (static). - - Each initial state is provided with the first token in ffesta_tokens[0], - which will be killed upon return to the final state (ffesta_zero or - ffelex_swallow_tokens passed through to ffesta_zero), so while it may - be changed to another token, a valid token must be left there to be - killed. Also, a "convenient" array of tokens are left in - ffesta_tokens[1..FFESTA_tokensMAX]. The initial state of this set of - elements is undefined, thus, if tokens are stored here, they must be - killed before returning to the final state. Any parser may also use - cross-state local variables by sticking a structure containing storage - for those variables in the local union ffestb_local_ (unless the union - goes on strike). Furthermore, parsers that handle more than one first or - second tokens (like _varlist_, which handles EXTERNAL, INTENT, INTRINSIC, - OPTIONAL, - PUBLIC, or PRIVATE, and _endxyz_, which handles ENDBLOCK, ENDBLOCKDATA, - ENDDO, ENDIF, and so on) may expect arguments from ffest in the - ffest-wide union ffest_args_, the substructure specific to the parser. - - A parser's responsibility is: to call either ffesta_confirmed or - ffest_ffebad_start before returning to the final state; to be the only - parser that can possibly call ffesta_confirmed for a given statement; - to call ffest_ffebad_start immediately upon recognizing a bad token - (specifically one that another statement parser might confirm upon); - to call ffestc functions only after calling ffesta_confirmed and only - when ffesta_is_inhibited returns FALSE; and to call ffesta_is_inhibited - only after calling ffesta_confirmed. Confirm as early as reasonably - possible, even when only one ffestc function is called for the statement - later on, because early confirmation can enhance the error-reporting - capabilities if a subsequent error is detected and this parser isn't - the first possibility for the statement. - - To assist the parser, functions like ffesta_ffebad_1t and _1p_ have - been provided to make use of ffest_ffebad_start fairly easy. - - Modifications: -*/ - -/* Include files. */ - -#include "proj.h" -#include "stb.h" -#include "bad.h" -#include "expr.h" -#include "lex.h" -#include "malloc.h" -#include "src.h" -#include "sta.h" -#include "stc.h" -#include "stp.h" -#include "str.h" - -/* Externals defined here. */ - -struct _ffestb_args_ ffestb_args;
