Summary of Changes
Hello @IvanHunters, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the boot-to-talos tool by introducing a -yes flag, enabling fully automated and non-interactive execution. This change streamlines the installation process for scripting and automation workflows, complemented by clear documentation updates to guide users on its usage.
Highlights
- New Feature: Non-interactive Mode: Introduced a new
-yescommand-line flag to allow theboot-to-talostool to run in a fully automated, non-interactive mode, bypassing all user prompts for confirmation or input. - Core Logic Modification: Modified the
ask,askRequired, andaskYesNofunctions inmain.goto respect the new-yesflag. When active,askandaskYesNowill automatically accept their default values, whileaskRequiredwill log a fatal error if a required input is missing, as it cannot be auto-filled. - Documentation Update: Updated
README.mdto include a new section on 'Non-interactive installation' with practical usage examples for the-yesflag. Additionally, a comprehensive table detailing all available command-line flags and their descriptions has been added for clarity.

Code Review
This pull request introduces a -yes flag for non-interactive execution, which is a great addition for automation. The changes in main.go correctly implement this by bypassing user prompts, and the README.md is updated to document the new flag and list all available command-line options.
My review includes a few suggestions to improve the implementation and documentation:
- In
README.md, I've suggested a minor tweak to the flag type for consistency. - In
main.go, I've recommended a more descriptive help message for the new flag and a refactoring of theaskYesNofunction to improve readability, performance, and consistency of the output in non-interactive mode.

For consistency with other flags in this table, the type for -extra-kernel-arg should be string instead of value. This makes the documentation clearer for users.

The help text for the -yes flag could be more descriptive to better align with its function and the documentation in README.md. A more explicit description would clarify that it accepts defaults and skips all interactive prompts.

| flag.BoolVar(&yesFlag, "yes", false, "Run non-interactively, accepting defaults and skipping confirmations") |

| } |

This implementation creates a new map on every function call, which is inefficient. Using an if/else block would be more readable and performant.
Additionally, printing the string "yes" or "no" instead of the boolean true or false makes the non-interactive output more consistent with the ask function's behavior and the user-facing prompt.
| if yesFlag { | |
| fmt.Printf("%s [%s]: %v\n", msg, map[bool]string{true: "yes", false: "no"}[def], def) | |
| return def | |
| } | |
| if yesFlag { | |
| defStr := "no" | |
| if def { | |
| defStr = "yes" | |
| } | |
| fmt.Printf("%s [%s]: %s\n", msg, defStr, defStr) | |
| return def | |
| } |

Great, a non-interactive is exactly what I was missing <3 |
