…ependency on the forked `go-flags` package and switching to the upstream version. Here's what was done: 1. **Updated `go.mod`**: - Removed the replace directive for `github.com/jessevdk/go-flags => github.com/alexcb/go-flags` - Upgraded from `go-flags v1.5.0` to `v1.6.1` which includes the `AllowBoolValues` flag that was needed 2. **Modified `util/flagutil/parse.go`**: - Added a preprocessing approach to handle the `ArgumentMod` functionality that existed in the fork - Implemented `getBoolFlagNames()` function to identify boolean flags using reflection - Implemented `preprocessArgs()` function to apply modifier functions to boolean flag values before parsing - This allows the same functionality (expanding variables in boolean flag values) without needing the fork's custom `ArgumentMod` callback 3. **Updated `earthfile2llb/interpreter.go`**: - Modified `flagValModifierFuncWithContext()` to work without the `IsBool()` method from the fork - Since our preprocessing only calls the modifier for boolean flags, we can safely assume all calls are for boolean flags 4. **Updated `features/features.go`**: - Removed the unused `instrumentVersion()` function that didn't modify anything anyway - Passed `nil` instead to `ParseArgsWithValueModifierAndOptions()` The alexcb fork added two features: 1. `ArgumentMod` callback - allowed modifying flag values before parsing 2. `IsBool()` method on Option - allowed checking if a flag is boolean The upstream `go-flags v1.6.1` includes `AllowBoolValues` which was the other key feature needed. By preprocessing arguments before passing them to go-flags, we achieve the same functionality without needing the fork. - All existing tests pass - The project builds successfully without errors or warnings - The functionality is preserved - boolean flags can still have their values modified (e.g., for variable expansion) before parsing This solution is cleaner and more maintainable as it uses the actively maintained upstream library rather than a stale fork from 2021.

Code Review
This pull request successfully removes the dependency on a forked go-flags package, migrating to the upstream version. This is a positive change for maintainability. The core of this change is the new argument pre-processing logic in util/flagutil/parse.go which replaces the ArgumentMod functionality from the fork. My review focuses on this new logic, and I've provided a few suggestions to enhance its robustness and align it with project conventions. Specifically, I've noted a violation of a project coding rule and pointed out some limitations in the new implementation concerning embedded structs and short flag parsing, which could be improved to prevent future issues. Overall, the changes are well-implemented and move the project in the right direction.
This commit addresses all review comments from gemini-code-assist in PR #320: 1. **Handle embedded structs in getBoolFlagNames()** - Added collectBoolFlags() helper function to recursively scan embedded structs - This ensures boolean flags in embedded structs are properly identified - Aligns with go-flags library's support for embedded structs 2. **Fix if-with-initializer linting violation** - Split variable declarations from if conditions - Moved shortTag and longTag declarations to separate lines - Prevents potential conflicts with project linting rules 3. **Improve short flag handling in preprocessArgs()** - Added support for short flags with attached values (-f=value) - Added handling for clustered short flags (-abc) - Properly handles modifier functions for last flag in clusters - More robust and closer to standard go-flags behavior 4. **Added comprehensive tests** - TestGetBoolFlagNames: tests simple structs, embedded structs, and nil data - TestPreprocessArgs: tests all short flag patterns and edge cases - All tests pass, verifying the improvements work correctly These changes improve maintainability and robustness while preserving all existing functionality.
Add blank lines before if statements after assignments in util/flagutil/parse.go to comply with wsl linter requirements. The wsl linter requires blank lines between different statement types for better code readability. All tests continue to pass after these formatting fixes.

Speaking loud. :) I'm curious why we need to copy values from a struct to a map.
I'm going look at the implementation later.
