Получите смещение текущего буфера в энергии (в частности, с помощью сценариев Python)
Я узнал много о Python путем чтения источника стандартной библиотеки, которая поставлется с Python. Я, кажется, не забываю иметь некоторых "a-ha!" моменты при чтении urllib2.py в частности.

If your vim is compiled with the +byte_offset option, then in a Python script after the usual import vim, you can use, e.g.:
vim.eval('line2byte(line("."))+col(".")')
to get the byte offset from start of file of the cursor position, and similarly for other marks. More generally, if you have a line/column pair this (assuming +byte_offset is how your vim was compiled with) is the way to get a byte offset (there's also a byte2line function to go the other way).
While the vim module does make a lot of functionality available directly to Python scripts in vim, I've found that vim.eval and vim.command are often the handiest (and sometimes the only;-) way to get in just as deep as needed;-). Oh, and I always try to have a vim compiled with +justabouteverything whenever I can;-).
You may also want to look at the statusline setting. This will add the bye offset to the statusline:
set statusline+=%o
See :h statusline
Just be careful because the default statusline is blank, and by appending the %o to it, you loose all the defaults.
