" 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. | |

" Keep Python keywords in alphabetical order inside groups for easy | |
" comparison with the table in the 'Python Language Reference' | |
" https://docs.python.org/2/reference/lexical_analysis.html#keywords, | |
" https://docs.python.org/3/reference/lexical_analysis.html#keywords. | |
" Groups are in the order presented in NAMING CONVENTIONS in syntax.txt. | |
" Exceptions come last at the end of each group (class and def below). | |
" | |
" Keywords 'with' and 'as' are new in Python 2.6 | |
" (use 'from __future__ import with_statement' in Python 2.5). | |
" | |
" Some compromises had to be made to support both Python 3 and 2. | |
" We include Python 3 features, but when a definition is duplicated, | |
" the last definition takes precedence. | |
" | |
" - 'False', 'None', and 'True' are keywords in Python 3 but they are | |
" built-ins in 2 and will be highlighted as built-ins below. | |
" - 'exec' is a built-in in Python 3 and will be highlighted as | |
" built-in below. | |
" - 'nonlocal' is a keyword in Python 3 and will be highlighted. | |
" - 'print' is a built-in in Python 3 and will be highlighted as | |
" built-in below (use 'from __future__ import print_function' in 2) | |
" - async and await were added in Python 3.5 and are soft keywords. | |

" The word boundaries are *not* the floating-point number boundaries | |
