Hi
I don't like vim syntax for writing scripts (set let a: g:variable). I
choose to use python environment for writing things in vim.
However I've encountered some problems.
One:
I have access to buffers from vim python object. However I don't know if I
can add buffer via vim objects or if this object is only for accessing the
buffers.
I cannot inherit Vim object. That is why I created my own wrapper for vim
native functions (line, getline, setline). I do that by vim.eval() command.
The problem is that to write into a buffer I have to switch into other
buffer and then I have to call in a loop setline which can only write into
current buffer.
My Write function in python makes vim call by vim.eval() as following
:b1 (select buffer1)
getline(...)
setline(...)
setlocal(...)
:b4 (select previous buffer)
When I am writing a lot of data to the buffer it takes time. It is too long
for me to accept. The speed of execution is only determined by python
environment? Or I shouldn't be using eval function, or is there any way to
speed things up?
For maximum efficiency and, most especially, portability, I would
recommend to learn Vim commands. They aren't really difficult, and their
documentation (the Vim help) is really top-class. Oh, the Perl, Python,
etc., interfaces do work, if you have them compiled-in and, if
dynamically linked, if you have the right versions of the libraries
available. But using them means exchanging messages both ways between
the Perl, Python, etc. interpreter and the Vim editor _in addition_ to
whatever tasks the interpreter and the editor normally do.
You _can_ use vim.command("edit foobar.py") in a python script to start
editing the file foobar.py (which will then be your current buffer,
unless Vim isn't willing to |abandon| (q.v.) the file you were editing
previously and raises an exception); but if you open a new buffer by typing
:py vim.command("edit foobar.py")
at the command-line (which is valid if Vim was compiled with +python,
the python libs are available, and you've already imported the vim
module into the python side of the interface), I will start thinking
that your preferred path from London to Westminster is through Rome.
Best regards,
Tony.
