LPeg is a new pattern-matching library for Lua, based on Parsing Expression
|
|
Grammars (PEGs).
|
|
|
|
The library offers several functions to create and compose patterns. With the
|
|
use of metamethods, several of these functions are provided as infix or prefix
|
|
operators. On the one hand, the result is usually much more verbose than the
|
|
typical encoding of patterns using the so called regular expressions (which
|
|
typically are not regular expressions in the formal sense). On the other hand,
|
|
first-class patterns allow much better documentation (as it is easy to comment
|
|
the code, to break complex definitions in smaller parts, etc.) and are
|
|
extensible, as we can define new functions to create and compose patterns.
