" Vim syntax file " Language: Python " Maintainer: Zvezdan Petkovic <zpetkovic@acm.org> " Last Change: 2016 Feb 20 " Credits: Neil Schemenauer <nas@python.ca> " Dmitry Vasiliev " " This version is a major rewrite by Zvezdan Petkovic. " " - introduced highlighting of doctests " - updated keywords, built-ins, and exceptions " - corrected regular expressions for " " * functions " * decorators " * strings " * escapes " * numbers " * space error " " - corrected synchronization " - more highlighting is ON by default, except " - space error highlighting is OFF by default " " Optional highlighting can be controlled using these variables.
