Pattern Expand VS Code Extension
Create files and directories using brace expansion patterns.
Features
- Brace lists:
{a,b,c} → a, b, c
- Numeric ranges:
{1..5} → 1, 2, 3, 4, 5
- Zero-padded ranges:
{01..10} → 01, 02, ..., 10
- Descending ranges:
{5..1} → 5, 4, 3, 2, 1
- Character ranges:
{a..f} → a, b, c, d, e, f
- Multiple groups (cartesian product):
{a,b}-{1,2} → a-1, a-2, b-1, b-2
- Nested groups:
{a,{b,c}} → a, b, c
Usage
- Open Command Palette (
Ctrl+Shift+P / Cmd+Shift+P)
- Run Pattern New File
