v1.2.2

🔥 Release preview

The variable name is now always shown in the prompt, even when a comment block is present above the variable. Before, only the comment was rendered, so it wasn't clear which variable you were answering for.

Template:

# Traefik entrypoint
USE_TLS=<*false|true>

Before:

◆  Traefik entrypoint
└  ▶

After:

◆  USE_TLS
│  Traefik entrypoint
└  ▶

The same applies to the secret-generated log line, which now reads DB_PASSWORD (Database password): Generated 32-char secret.

🤔 Changes

• Always render the variable name in interactive prompts and in the secret-generated info log

v1.2.1

🔥 Release preview

Fix dollar sign ($) escaping in .env values to prevent shell variable interpolation issues.

Before: Passwords like abc$def were written unescaped, causing $def to be interpreted as a variable reference when sourced.

After: Values containing $ are now properly quoted and escaped:

# Input password: $Q7Kyp(vtU$eDRG#YSPizqW)BB3DePyi
# Output:
PASSWORD="\$Q7Kyp(vtU\$eDRG#YSPizqW)BB3DePyi"
