A friendly interface for interacting with Vim using Python.

Installation

Examples:

• ~/vimfiles/.venv/bin/pip.exe install --upgrade vimlib
• cd ~/vimfiles && poetry install vimlib

Usage

Current

vimlib offers a convenient way to interact with the current environment, much like Vim's built-in current object.

from pyvim import current

Echo

vimlib offers a convenient way to print to Vim's stdout in a colorful, and flexible, manner.

import pyvim


# Print to STDOUT
pyvim.echo("Hello!")
# Print with chosen highlight group
pyvim.echo("Hello!", "PyVimSuccess")  # Built-In Green
pyvim.echo("Hello!", "PyVimCaution")  # Built-In Yellow
pyvim.echo("Hello!", "PyVimDanger")   # Built-In Red

Highlight Groups

vimlib offers a convenient way to interact with highlight groups.

from pyvim import current


# Boolean. Check if a highlight group is available
has_highlight = 'MyHighlightGroup' in pyvim.current.highlights

Visual Selection

vimlib offers a convenient way to interact with highlighted text. Also highlights the most recent highlighted text.

from pyvim import current


# String with the current, or last, selection.
# Support basic, linewise, and block visual highlights
selection = pyvim.current.selection

Utilities

vimlib offers convenient utilities.

System Commands

Note: Chaining will stack <CR> and other tokens.

from pyvim.utilities import wrap_vim_command


wrapped_command: str = wrap_vim_command(
    command="!py %",
    silent=True,
    clear=True,
)

print(wrapped_command)
# ":<C-U>silent !py %<CR>

Examples

>>> print(wrap_vim_command('w'))
:<C-u>w<CR>

>>> print(wrap_vim_command('w!', silent=True))
:<C-u>silent w!<CR>

Mappings

vimlib offers a convenient way to interact Vim mappings.

>>> import pyvim
>>>
>>>
>>> # Set <Leader>r to write current buffer to disk.
>>> # Equivalent to `:nmap <Leader>r :<C-u>silent w<CR>` in Vim.
>>> set_mapping('nmap', '<Leader>r', ':<C-u>silent w<CR>')

)

result = vim_function(...)
