vim.buffers *python-buffers* |

A mapping object providing access to the list of vim buffers. The |

object supports the following operations: > |
|
8
|
|
|
:py b = vim.buffers[i] # Indexing (read-only) |
|
9
|
|
|
:py b in vim.buffers # Membership test |
|
10
|
|
|
:py n = len(vim.buffers) # Number of elements |
|

|
|
|
:py for b in vim.buffers: # Iterating over buffer list |
|
12
|
|
|
|
|

|
The key for indexing into vim.buffers[] is the buffer number as described in |
|

*python-buffer*. |
