Sort & Unique Lines

A VS Code extension that sorts and removes duplicate lines instantly. Select specific lines or leave unselected to process the entire file, then press Alt+W.

Requirements

VS Code 1.130 or newer. Older builds will not list or install this extension.

Installation

From Marketplace

Install from VS Code Marketplace

Or search "Sort & Unique Lines" in the Extensions view (Ctrl+Shift+X).

From VSIX

Download the .vsix file from releases, then:

code --install-extension sort-unique-lines-1.2.0.vsix

From Source

git clone https://github.com/LabinatorSolutions/sort-unique-lines.git
cd sort-unique-lines
bun install
bun run compile
bun run package
code --install-extension sort-unique-lines-*.vsix

Usage

1. Select lines in any editor (or select nothing to process the entire file)
2. Press Alt+W
3. The selection is replaced with sorted, deduplicated lines
4. Undo with Ctrl+Z as usual

With multiple cursors, every selection is sorted independently in a single undo step. Selections that land on the same lines are merged first.

Features

• Sorts lines ascending or descending
• Removes duplicate lines (case-insensitive dedup by default)
• Trims leading/trailing whitespace (configurable)
• Strips blank lines (configurable)
• Case-sensitive mode available
• Works on a selection, several multi-cursor selections, or the entire file
• Settings are language-overridable, so .txt can behave differently from source files
• Zero runtime dependencies

Configuration

All settings live under File > Preferences > Settings → search "Sort & Unique Lines".

Setting	Type	Default	Description
sort-unique-lines.sortOrder	"ascending" | "descending"	"ascending"	Sort direction
sort-unique-lines.caseSensitive	boolean	false	Treat uppercase/lowercase as different
sort-unique-lines.removeBlankLines	boolean	true	Strip empty and whitespace-only lines
sort-unique-lines.trimLines	boolean	true	Trim whitespace from each line before sorting

All four are language-overridable — scope them per language with a "[markdown]": { ... } block in your settings.

Keybinding

Default: Alt+W
Change it in File > Preferences > Keyboard Shortcuts → search "Sort & Unique Lines".
