#include "chartab.ih"
/*
The regular expression of chartab-elements consists of the following
parts:
"[[:space:]]*" - start with optional whitespace
"'((\\\\)?.)'" - followed by one character between
single quotes, optionally preceded
by a backslash
"[[:space:]]*" - followed by optional white space
"=" - and an '=' sign
"[[:space:]]*" - followed by optional white space
"\"(((\\\\.)|[^\"])*)\"" - followed by any series of chars,
each optionally preceded by a \,
enclosed in double string quotes
d_regex_oct is identical to d_regex, but has the character expression
"'\\\\([0-7]{3})'" - three octal digits preceded by a \,
surrounded by single quotes.
Example: '\123'
d_regex_hex is identical to d_regex, but has the character expression
"'0x([0-9a-fA-F]{2})'" - 0x followed by 2 hex digits,
surrounded by single quotes.
Example: '0xab'
