Cast is a Go library that provides easy and safe conversion (casting) between different types in Go programs. Especially when dealing with interface{} or dynamic/reflect-heavy code, it becomes cumbersome to assert types or convert values reliably; cast addresses that by offering a suite of functions to convert from any input to the target type with predictable behaviour. Rather than relying purely on raw type assertions, it offers ToInt, ToString, ToBool, ToTime, etc., and their...

Traceway is an OpenTelemetry-native observability platform that brings logs, traces, metrics, exceptions, session replay, real user monitoring, and AI tracing into one open-source product. It is designed so teams can point an OTLP exporter at it without adding vendor-specific SDKs or extra collector glue. The platform is aimed at small and growing engineering teams that want practical visibility into what is happening inside their systems and how to fix issues faster. It can be self-hosted...

Go-datastructures is a collection of useful, performant, and threadsafe Go datastructures. Interval tree for collision in n-dimensional ranges. Implemented via a red-black augmented tree. Extra dimensions are handled in simultaneous inserts/queries to save space although this may result in suboptimal time complexity. Intersection determined using bit arrays. In a single dimension, inserts, deletes, and queries should be in O(log n) time. Bitarray used to detect existence without having to...

...Existing WebSocket implementations do not allow users to reuse I/O buffers between connections in clear way. This library aims to export efficient low-level interface for working with the protocol without forcing only one way it could be used. Library is tagged as v1* so its API must not be broken during some improvements or refactoring. Example applications using ws are developed in separate repository ws-examples. We can apply the same pattern to read and write structured responses through a JSON encoder and decoder.Zero-copy upgrade helps to avoid unnecessary allocations and copying while handling HTTP Upgrade request.

gon is a simple, no-frills tool for signing and notarizing your CLI binaries for macOS. gon is available as a CLI that can be run manually or in automation pipelines. It is also available as a Go library for embedding in projects written in Go. gon can sign and notarize binaries written in any language. Beginning with macOS Catalina (10.15), Apple is requiring all software distributed outside of the Mac App Store to be signed and notarized. Software that isn't properly signed or notarized...

go-cache is an in-memory key:value store/cache similar to memcached that is suitable for applications running on a single machine. Its major advantage is that, being essentially a thread-safe map[string]interface{} with expiration times, it doesn't need to serialize or transmit its contents over the network. Any object can be stored, for a given duration or forever, and the cache can be safely used by multiple goroutines. Although go-cache isn't meant to be used as a persistent datastore,...
