This is expected to be called by a parser routine that has
- recognized'\N' and needs to handle the rest. RExC_parse is
+ recognized '\N' and needs to handle the rest. RExC_parse is
expected to point at the first char following the N at the time
of the call.
+
+ The \N may be inside (indicated by valuep not being NULL) or outside a
+ character class.
+
+ \N may begin either a named sequence, or if outside a character class, mean
+ to match a non-newline. For non single-quoted regexes, the tokenizer has
+ attempted to decide which, and in the case of a named sequence converted it
+ into one of the forms: \N{} (if the sequence is null), or \N{U+c1.c2...},
+ where c1... are the characters in the sequence. For single-quoted regexes,
+ the tokenizer passes the \N sequence through unchanged; this code will not
+ attempt to determine this nor expand those. The net effect is that if the
+ beginning of the passed-in pattern isn't '{U+' or there is no '}', it
+ signals that this \N occurrence means to match a non-newline.
+
+ Only the \N{U+...} form should occur in a character class, for the same
+ reason that '.' inside a character class means to just match a period: it
+ just doesn't make sense.
If valuep is non-null then it is assumed that we are parsing inside
of a charclass definition and the first codepoint in the resolved
string is returned via *valuep and the routine will return NULL.
In this mode if a multichar string is returned from the charnames
- handler a warning will be issued, and only the first char in the
+ handler, a warning will be issued, and only the first char in the
sequence will be examined. If the string returned is zero length
then the value of *valuep is undefined and NON-NULL will
be returned to indicate failure. (This will NOT be a valid pointer
to a regnode.)
- If value is null then it is assumed that we are parsing normal text
- and inserts a new EXACT node into the program containing the resolved
- string and returns a pointer to the new node. If the string is
- zerolength a NOTHING node is emitted.
-
+ If valuep is null then it is assumed that we are parsing normal text and a
+ new EXACT node is inserted into the program containing the resolved string,
+ and a pointer to the new node is returned. But if the string is zero length
+ a NOTHING node is emitted instead.
+
On success RExC_parse is set to the char following the endbrace.
- Parsing failures will generate a fatal errorvia vFAIL(...)
-
- NOTE: We cache all results from the charnames handler locally in
- the RExC_charnames hash (created on first use) to prevent a charnames
- handler from playing silly-buggers and returning a short string and
- then a long string for a given pattern. Since the regexp program
- size is calculated during an initial parse this would result
- in a buffer overrun so we cache to prevent the charname result from
- changing during the course of the parse.
