RFC: line oriented statefull regex parser

[masatake]

After studying ctags for a long time, I have recognized what users, including myself, want is the way to define a "line-oriented stateful regex parser."

Currently, we have three:

• --regex-: an option for defining a line-oriented stateless regex parser,
• --mline-regex-: an option for defining a multiline-oriented stateless regex parser, and
• --_mtable-regex-: an option for defining byte-oriented stateful regex parser.

We can write a line-oriented stateful regex parser with --_mtable-regex. However, the parser definition with the option becomes a bit complicated. --_mtable-regex is too powerful for the purpose.

I'm looking for a good option name for defining a line-oriented stateful regex parser.

• --lregex-=TABLE/PATTERN/...
• --regex2-=TABLE/PATTERN/...
• --ltable-=TABLE/PATTERM/...
• --pcre2-=TABLE/PATTERN/...
• --stable-=TABLE/PATTERN/...
• ...

Which one do you like?
