Oops is a Go library for structured error handling that serves as a drop-in replacement for the standard error type. It provides a fluent builder pattern to attach rich contextual information (error codes, domains, tags, key-value attributes, user/tenant data, HTTP request/response, timestamps, durations, hints, ownership) to errors, along with automatic stack trace capture and optional source code fragment extraction. The library implements the standard error interface, supports error wrapping and chaining, panic recovery, assertions, and integrates with major Go logging libraries (zap, zerolog, logrus, slog) via separate formatter packages. Its architecture centers on an immutable option chain (functional options) that defers stack frame symbolization to first read, minimizing allocation overhead for errors that are created but never inspected. Key entry points are the package-level functions (Wrap, Wrapf, New, Errorf, Join, Recover, Recoverf, Assert, Assertf) and the OopsErrorBuilder chainable methods. External dependencies are minimal: only github.com/oklog/ulid/v2, github.com/samber/lo, and go.opentelemetry.io/otel/trace for optional OpenTelemetry span context extraction. The codebase is well-tested, benchmarked, and follows Go best practices with comprehensive linting and security scanning.
This repository is a Cursor IDE trial reset tool that modifies system configurations to generate new unique identifiers for Cursor's telemetry fields. It consists of platform-specific scripts (shell for Linux/macOS, PowerShell for Windows) that stop Cursor processes, modify configuration files and registry entries, inject JavaScript hooks into Cursor's main.js files to intercept device identifier generation at runtime, and disable auto-update features. The tool works by creating persistent fake identifiers for telemetry.machineId, telemetry.macMachineId, telemetry.devDeviceId, and telemetry.sqmId, effectively resetting Cursor's trial period detection mechanisms.
