pyrime

rime for python, attached to prompt-toolkit keybindings for some prompt-toolkit applications such as ptpython.

This project is consist of two parts:

• A python binding of librime
• A librime frontend on ptpython

Dependence

• librime

# Ubuntu
sudo apt-get -y install librime-dev librime1 pkg-config
sudo apt-mark auto librime-dev pkg-config
# ArchLinux
sudo pacman -S --noconfirm librime pkg-config
# Android Termux
apt-get -y install librime pkg-config
# Nix
# use nix-shell to create a virtual environment then build
# homebrew
brew install librime pkg-config
# Windows msys2
pacboy -S --noconfirm pkg-config librime gcc

Usage

Binding

from pyrime.key import Key
from pyrime.session import Session
from pyrime.ui import UI

session = Session()
key = Key.new("n")
ui = UI()
if not session.process_key(key.code, key.mask):
    raise Exception
context = session.get_context()
if context is None:
    raise Exception
content, _ = ui.draw(context)
print("\n".join(content))

A simplest example can be found by:

pip install pyrime[cli]
python -m pyrime

By default, pyrime search ibus/fcitx/trime's config paths. You can see where it found:

from pyrime.api import Traits

print(Traits.user_data_dir)

Frontend

~/.config/ptpython/config.py:

from ptpython.repl import PythonRepl
from prompt_toolkit.filters.app import (
    emacs_insert_mode,
    vi_insert_mode,
    vi_navigation_mode,
)
from prompt_toolkit.key_binding.key_processor import KeyPressEvent
from pyrime.ptpython.rime import Rime


def configure(repl: PythonRepl) -> None:
    rime = Rime(repl)

    @repl.add_key_binding("c-^", filter=rime.insert_mode)
    def _(event: KeyPressEvent) -> None:
        rime.is_enabled = not rime.is_enabled

If you have a special rime config path, you can:

import os

from ptpython.repl import PythonRepl
from pyrime.session import Session
from pyrime.api import Traits


def configure(repl: PythonRepl) -> None:

    rime = Rime(
        repl, Session(Traits(user_config_dir=os.path.expand("~/.config/rime")))
    )

If you have defined some key bindings which will disturb rime, try:

    @repl.add_key_binding("c-h", filter=emacs_insert_mode & ~rime.preedit_available())
    def _(event: KeyPressEvent) -> None:
        pass

If you want to exit rime in vi_navigation_mode, try:

    @repl.add_key_binding("escape", filter=emacs_insert_mode)
    def _(event: KeyPressEvent) -> None:
        """.

        :param event:
        :type event: KeyPressEvent
        :rtype: None
        """
        # rime.is_enabled will be stored to rime.iminsert
        rime.is_enabled = False
        event.app.editing_mode = EditingMode.VI
        event.app.vi_state.input_mode = InputMode.NAVIGATION

    # and a, I, A, ...
    @repl.add_key_binding("i", filter=vi_navigation_mode)
    def _(event: KeyPressEvent) -> None:
        """.

        :param event:
        :type event: KeyPressEvent
        :rtype: None
        """
        event.app.editing_mode = EditingMode.EMACS
        event.app.vi_state.input_mode = InputMode.INSERT
        # restore rime
        rime.is_enabled = rime.iminsert

It will remember rime status and enable it when reenter vi_insert_mode or emacs_insert_mode.

Some predefined key bindings are provided.
