Data Fields | |
| chew_public_state_t | chew_public_state |
| size_t | single_quote_length |
| bool | escape |
Current number of input characters commencing with the last '\'' that possibly opens a quotation in single quotes, or 0 whenever we are not within such a sequence. If this length ever exceeds 4 within a call to chew(), we conclude that it the sequence is not a quotation but simply characters following a free-standing independant apostrophe, and reset the value to 0.
The sole reason for tracking this length is to identify the 3-character sequence '"' as a quotation of the double-quote character and avoid falsely detecting the start or end of a quotation in double-quotes. The equivalent 4-character sequence '"' is unproblematic because the double-quote will be seen to be escaped.
