1230 /* Function argument lists are arguably the most complex part in the
1231 * parser. They are pretty tricky to understand because of the way
1232 * they are processed, and because of optional arguments that can be
1233 * omitted. When there are several optional arguments in a row,
1234 * omitting one automatically omits all following arguments. Optional
1235 * arguments can only be omitted when either
1237 * a) the omission is explicitly started with \default
1238 * b) the omission is implicitly started by an argument not matching
1239 * its predicate, and there is a mandatory argument later that can
1240 * "catch" the argument that does not fit.
1242 * When argument parsing starts, the lexer pushes EXPECT_SCM tokens
1243 * (corresponding to mandatory arguments and having a predicate
1244 * function as semantic value) or EXPECT_OPTIONAL EXPECT_SCM (where
1245 * the semantic value of the EXPECT_OPTIONAL token is the default to
1246 * use when the optional argument is omitted, and EXPECT_SCM again has
1247 * the argument predicate as semantic value) in reverse order to the
1248 * parser, followed by EXPECT_NO_MORE_ARGS. The argument list is then
1249 * processed inside-out while actual tokens are consumed.
1251 * This means that the argument list tokens determine the actions
1252 * taken as they arrive. The structure of the argument list is known
1253 * to the parser and stored in its parse stack when the first argument
1254 * is being parsed. What the parser does not know is which predicates
1255 * will match and whether or not \default will be appearing in the
1256 * argument list, and where.
1258 * Many of the basic nonterminals used for argument list scanning come
1259 * in a "normal" and a "closed" flavor. A closed expression is one
1260 * that can be parsed without a lookahead token. That makes it
1261 * feasible for an optional argument that may need to be skipped:
1262 * skipping can only be accomplished by pushing back the token into
1263 * the lexer, and that only works when there is no lookahead token.
1265 * Sequences of 0 or more optional arguments are scanned using either
1266 * function_arglist_backup or function_arglist_nonbackup. The first
1267 * is used when optional arguments are followed by at least one
1268 * mandatory argument: in that case optional arguments may be skipped
1269 * by either a false predicate (in which case the expression will be
1270 * pushed back as one or more tokens, preceded by a BACKUP token) or
1271 * by using \default.
1273 * If optional arguments are at the end of the argument list, they are
1274 * instead scanned using function_arglist_nonbackup: here the only
1275 * manner to enter into skipping of optional arguments is the use of
1278 * The argument list of a normal function call is parsed using
1279 * function_arglist. The part of an argument list before a mandatory
1280 * argument is parsed using function_arglist_optional.
1282 * The difference is that leading optional arguments are scanned using
1283 * function_arglist_nonbackup and function_arglist_backup,
1286 * Most other details are obvious in the rules themselves.
