Description:
pygmars is a simple lexing and parsing library designed to craft lightweight
lexers and parsers using regular expressions. pygmars allows you to craft
simple lexers that recognizes words based on regular expressions and identify
sequences of words using lightweight grammars to obtain a parse tree. The
lexing task transforms a sequence of words or strings (e.g. already split in
words) in a sequence of Token objects, assigning a label to each word and
tracking their position and line number. In particular, the lexing output is
designed to be compatible with the output of Pygments lexers. It becomes
possible to build simple grammars on top of existing Pygments lexers to perform
lightweight parsing of the many (130+) programming languages supported by
Pygments. The parsing task transforms a sequence of Tokens in a parse Tree
where each node in the tree is recognized and assigned a label. Parsing is
using regular expression-based grammar rules applied to recognize Token
sequences. These rules are evaluated sequentially and not recursively: this
keeps things simple and works very well in practice. This approach and the
rules syntax has been battle-tested with NLTK from which pygmars is derived.
