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.
