Introduction
In this tutorial we learn how to install python-funcparserlib on CentOS 7.
What is python-funcparserlib
Parser combinators are just higher-order functions that take parsers as their arguments and return them as result values. Parser combinators are * First-class values * Extremely composable * Tend to make the code quite compact * Resemble the readable notation of xBNF grammars Parsers made with funcparserlib are pure-Python LL(*) parsers. It means that it’s very easy to write them without thinking about look-aheads and all that hardcore parsing stuff. But the recursive descent parsing is a rather slow method compared to LL(k) or LR(k) algorithms. So the primary domain for funcparserlib is parsing little languages or external DSLs (domain specific languages).
We can use yum or dnf to install python-funcparserlib on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install python-funcparserlib.
