Hungry Backspace

Hungry Backspace for Sublime Text

Overview

This small plugin brings to Sublime Text the “hungry backspace” feature from IntelliJ. The hungry backspace retains the scope (indentation) when the backspace key is pressed on an empty line.

Live demo

Warning

This plugin is NOT meant to replace backspace entirely, it is meant to be used in conjunction with the original backspace function which is now accessed by Shift+Backspace

(!) USE THE DEFAULT BACKSPACE WHENEVER YOU NEED IT USING SHIFT+BACKSPACE

Version

1.1.4

What's new

New features demo

Added 3 new features based on IntelliJ's smart backspace, of which two are experimental and one is enabled by default.

• [Experimental] When you press backspace with your cursor at line start if the indentation level of the current line is wrong it is reindented Options: “enabled”/ “disabled” / “forced”

  "right_to_left_backspacing" : true

• If you are on line start and the upper line is empty the current line gets moved one up

  "consume_above_line": true

• [Experimental] If you are on line start and press backspace and the upper line is not empty the current lines contents get moved up Options: “enabled”/ “disabled” / “forced”

  “backspace_line_content_move”: “enabled”
