Create reusable error handling helpers to reduce boilerplate and
enforce consistency across the codebase:
- FatalError(format, args...): writes "Error: ..." to stderr and exits
- FatalErrorWithHint(message, hint): includes actionable suggestion
- WarnError(format, args...): writes "Warning: ..." to stderr
Prototyped in create.go to validate the approach - converted 13 error
patterns and 5 warning patterns. This reduces code from:
fmt.Fprintf(os.Stderr, "Error: %v\n", err)
os.Exit(1)
To simply:
FatalError("%v", err)
Also fixed countIssuesInJSONLFile reference after earlier refactoring.
See docs/ERROR_HANDLING.md for the three-pattern guideline.

// FatalError writes an error message to stderr and exits with code 1.
|
|
// Use this for fatal errors that prevent the command from completing.
|
|
//
|
|
// Pattern A from ERROR_HANDLING.md:
|
|
// - User input validation failures
|
|
// - Critical preconditions not met
|
|
// - Unrecoverable system errors
|
|
//
|
|
// Example:
|
|
//
|
|
// if err := store.CreateIssue(ctx, issue, actor); err != nil {
|
|
// FatalError("%v", err)
|
|
// }

|
|
|
|
// FatalErrorWithHint writes an error message with a hint to stderr and exits.
|
|
// Use this when you can provide an actionable suggestion to fix the error.
|
|
//
|
|
// Example:
|
|
//
|
|
// FatalErrorWithHint("database not found", "Run 'bd init' to create a database")
|
|

// WarnError writes a warning message to stderr and returns.
|
|
// Use this for optional operations that enhance functionality but aren't required.
|
|
//
|
|
// Pattern B from ERROR_HANDLING.md:
|
|
// - Metadata operations
|
|
// - Cleanup operations
|
|
// - Auxiliary features (git hooks, merge drivers)
|
|
//
|
|
// Example:
|
|
//
|
|
// if err := createConfigYaml(beadsDir, false); err != nil {
|
|
// WarnError("failed to create config.yaml: %v", err)
|
|
// }
