Naming pattern: --name

Default: {index}-{first}

# Zero-padded index: 001, 002...
--name "{index:3}-{first}"

# Use column value: 001-Budi
--name "{index:3}-{Source Text}"

# Slugified: 001-budi-santoso
--name "{index:3}-{slug:Source Text}"

Tokens

Token	Example	Description
{index}	1	1-based row number
{index:N}	001	Zero-padded to N digits
{first}	Budi	First column value (sanitized)
{Column}	Budi	Any column value (sanitized)
{slug:Column}	budi-santoso	Lowercase, accents removed, spaces → -

Collision handling

Duplicate names get -2, -3, … appended automatically:

1-Budi.mp4
2-Budi.mp4
3-Budi-2.mp4

Windows reserved names

CON, PRN, AUX, NUL, COM1–COM9, LPT1–LPT9 → prefixed with _:

_CON.mp4
_COM1.mp4

Config file

Set defaults in lakreet.config.json:

{
  "out": "dist",
  "name": "{index:3}-{slug:Source Text}",
  "render": {
    "format": "webm",
    "quality": "best",
    "resolution": "full"
  }
}

CLI flags override config.
