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-<LANG>: an option for defining a line-oriented stateless regex parser,
• --mline-regex-<LANG>: an option for defining a multiline-oriented stateless regex parser, and
• --_mtable-regex-<LANG>: 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-<LANG>=TABLE/PATTERN/...
• --regex2-<LANG>=TABLE/PATTERN/...
• --ltable-<LANG>=TABLE/PATTERM/...
• --pcre2-<LANG>=TABLE/PATTERN/...
• --stable-<LANG>=TABLE/PATTERN/...
• ...

Which one do you like?
