Sublime Text, как запоминать позицию курсора в файлах ?

4.7.2022 - 164 просмотрa ;)

Создайте файл в Сабле:

sublime_text_4\Packages\User\cursor_positions.py

В него кладем

# cursor_positions.py

"""
A plugin for SublimeText which saves (remembers) cursor position when
a file is closed.
Install it by copying this file in ~/.config/sublime-text-3/Packages/User/
directory (Linux).

Сабля загрузит плагин и начнет запоминать позицию курсора.

Да есть вариант на странице Giampaolo Rodola (gmpy.dev)

Но у него коряво написано и на Венде не работает, а у меня работает .. )))

Если чего-то не будет работать конфиг лежит

\sublime_text_4\Data\Local\cursor_positions.session.json

там все позиции курсоров

Старый плагин BufferScroll почему-то не устанавливается на Sublime Text 4.

Считайте что вам повезло !
