* Lex everything except SGML, multiline, SHEBANG * Prepend SHEBANG#! to tokens * Support SGML tag/attribute extraction * Multiline comments * WIP cont'd; productionifying * Compile before test * Add extension to gemspec * Add flex task to build lexer * Reentrant extra data storage * regenerate lexer * use prefix * rebuild lexer on linux * Optimise a number of operations: * Don't read and split the entire file if we only ever use the first/last n lines * Only consider the first 50KiB when using heuristics/classifying. This can save a *lot* of time; running a large number of regexes over 1MiB of text takes a while. * Memoize File.size/read/stat; re-reading in a 500KiB file every time `data` is called adds up a lot. * Use single regex for C++ * act like #lines * [1][-2..-1] => nil, ffs * k may not be set
