" 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.
