NetplanTUI Version 1.0.2

NetplanTUI – Version 1.0.2

Networking, Validation & UI Enhancements

IP & CIDR Handling

• Added robust IPv4 and IPv6 validation for both single IPs and CIDR notation.
• Supports host-address CIDRs (e.g., 192.168.0.1/24) and automatically normalizes them to proper network prefixes (e.g., 192.168.0.0/24) in YAML output.
• Invalid input is preserved and displayed with inline token highlighting, allowing users to fix only the incorrect parts.

IPv4 / IPv6 Mode Support

• Introduced an IP Mode toggle: IPv4, IPv6, or Both.
• YAML generation adapts based on the selected mode:
  • Correctly sets dhcp4 / dhcp6
  • Outputs only the relevant address and gateway fields
  • Adds support for separate gateway4 and gateway6 when both protocols are enabled.

Nameserver Validation

• Nameservers are individually validated as IPv4/IPv6 addresses.
• Supports comma-separated lists with inline highlighting for invalid entries.

Interface Discovery

• Detects system interfaces using getifaddrs.
• Interfaces are shown in a selectable list, simplifying the “Interface Name” input.

DHCP-Aware UI

• When DHCP is enabled, address/gateway/nameserver fields are automatically hidden to reduce clutter.

Help Menu

• Added an in-app Help screen explaining:
  • Field purposes
  • CIDR rules
  • Validation behavior
  • YAML generation logic

YAML Generation Improvements

• YAML preview now includes:
  • dhcp4 / dhcp6
  • gateway4 / gateway6
  • Normalized CIDR addresses
  • Validated nameservers block
• Preview displayed in the TUI before writing config files.
