buffer-matcher 0.1.1

More efficiently match bytes using memoryviews to prevent copying

Buffer matchers, as I refer to them, are wrappers around bytes that allow easier, more memory-efficient reading and pattern matching

These are used in my programming language Caustic's Lexer

Beyond base classes, this package provides two buffer matcher classes:

• DynamicBufferMatcher / dynamic.BufferMatcher
• StaticBufferMatcher / static.BufferMatcher

The buffer classes shown above can be .read(), .seek()ed through, and .match()ed against strings, callables, or regular expressions

The "dynamic" and "static" in the names refer to how they calculate line and column numbers -- namely, the "dynamic" buffer matcher calculates line and column numbers via properties, every time they are accessed; whilst the "static" buffer matcher calculates line and column numbers only when the position of the matcher is changed. "Dynamic" buffer matchers are recommended if line and column numbers are accessed less often than the position is changed, and vice-versa for "static" buffers.
