11 Regular parsing

Programming languages have poor reading libraries since the lexical information that can be specified is directly tied to the structure of the language. For example, in C it’s hard to read a rational number because there is no type rational. Programs have been written to circumvent this problem: Lex [Lesk75], for example, is one of them. We choose to incorporate in Bigloo a set of new functions to assist in such parsing. The syntax for regular grammar (also known as regular analyser) of Bigloo 2.0 (the one described in this document) is not compatible with former Bigloo versions.
