Refactor: Extract duplicate compilation loops into shared helper

[Copilot]

Two functions in pkg/cli/compile_command.go contained identical ~20-line compilation loops, differing only in file existence checking for watch mode.

Changes

• Added compileSingleFile() helper that consolidates per-file compilation logic with configurable existence checking
• Updated compileAllWorkflowFiles() to call helper with checkExists=false (bulk mode)
• Updated compileModifiedFiles() to call helper with checkExists=true (watch mode)
• Standardized verbose output to use fmt.Fprintf(os.Stderr, ...) consistently

Before

for _, file := range mdFiles {
    stats.Total++
    compileLog.Printf("Compiling: %s", file)
    if verbose {
        fmt.Printf("🔨 Compiling: %s\n", file)
    }
    if err := CompileWorkflowWithValidation(compiler, file, verbose, false, false, false, false, false); err != nil {
        fmt.Fprintln(os.Stderr, err.Error())
        stats.Errors++
        stats.FailedWorkflows = append(stats.FailedWorkflows, filepath.Base(file))
    } else {
        compileLog.Printf("Successfully compiled: %s", file)
    }
}

After

for _, file := range mdFiles {
    compileSingleFile(compiler, file, stats, verbose, false)
}

Eliminates ~40 lines of duplication. Future changes to compilation logic only require a single update.

Summary

The workflow compilation helpers now contain two near-identical loops that compile markdown workflows, track statistics, and emit logging. Maintaining both copies will cause divergence when behaviour changes.

Duplication Details

Pattern: Reused per-file compilation loop

• Severity: Medium
• Occurrences: 2
• Locations:
  • pkg/cli/compile_command.go (lines 887-903)
  • pkg/cli/compile_command.go (lines 937-959)
• Code Sample:

for _, file := range files {
    stats.Total++
    compileLog.Printf("Compiling: %s", file)
    if verbose {
        fmt.Fprintf(os.Stderr, "🔨 Compiling: %s\n", file)
    }
    if err := CompileWorkflowWithValidation(compiler, file, verbose, false, false, false, false, false); err != nil {
        fmt.Fprintln(os.Stderr, err.Error())
        stats.Errors++
        stats.FailedWorkflows = append(stats.FailedWorkflows, filepath.Base(file))
    } else {
        compileLog.Printf("Successfully compiled: %s", file)
    }
}

Impact Analysis

• Maintainability: Changes to logging, statistics, or validation need to be updated in two places, risking inconsistent behaviour.
• Bug Risk: Fixes for edge cases (e.g., error handling or verbose output) may be applied to one loop but not the other.
• Code Bloat: Duplicated ~15-line block inflates the command logic and obscures differences between watch and bulk modes.

Refactoring Recommendations

1. Extract a shared helper

   • Extract the per-file compilation logic into compileSingleFile(...) (or similar) used by both loops.
   • Estimated effort: 2-3 hours.
   • Benefits: Ensures consistent logging, statistics, and error handling in every compilation mode.

2. Unify post-loop housekeeping

   • Consolidate the .gitattributes update into the shared helper or a dedicated function invoked from both paths.
   • Estimated effort: 1 hour.
   • Benefits: Removes duplicated warning handling and allows future enhancements (e.g., retries) in one spot.

Implementation Checklist

• Review duplication findings
• Prioritize refactoring tasks
• Create refactoring plan
• Implement changes
• Update tests
• Verify no functionality broken

Pull Request Overview

This PR refactors duplicate compilation logic in the CLI by extracting a shared helper function. The main goal is to consolidate two nearly identical ~20-line compilation loops that only differed in file existence checking, reducing code duplication and improving maintainability.

Key changes:

• Added compileSingleFile() helper function to handle per-file compilation with configurable existence checking
• Refactored compileAllWorkflowFiles() and compileModifiedFiles() to use the new helper
• Updated GitHub Actions versions in the super-linter lock file to use pinned SHAs

The super-linter action should be pinned to a SHA commit rather than a tag, consistent with the security best practices described in the coding guidelines. All other actions in this file use SHA pinning (e.g., actions/checkout@08c6903cd8c0fde910a37f88322edcb5dd907a8). Pin this to the SHA for v8.2.1 with a comment indicating the version.
