The following python modules are automatically imported into the scope before
'expression' is evaluated: 're', 'os', 'vim', 'string', 'random'.
Also, the following variables are defined:
'window' - alias for 'vim.current.window'
'buffer' - alias for 'vim.current.window.buffer'
'cursor' - alias for 'vim.current.cursor'
'line' and 'column' - aliases for cursor position
Global variable `snip` will be available with following properties:
'snip.window' - alias for 'vim.current.window'
'snip.buffer' - alias for 'vim.current.window.buffer'
'snip.cursor' - cursor object, which behaves like
'vim.current.window.cursor', but zero-indexed and with following
additional methods:
- 'preserve()' - special method for executing pre/post/jump actions;
- 'set(line, column)' - sets cursor to specified line and column;
- 'to_vim_cursor()' - returns 1-indexed cursor, suitable for assigning
to 'vim.current.window.cursor';
'snip.line' and 'snip.column' - aliases for cursor position (zero-indexed);
Keep in mind, that lines in vim numbered from 1, and lists in python starts
from 0, so to access the current line you need to use 'line-1'.
