    Mergo

    Mergo

    Mergo: merging Go structs and maps since 2013

    A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements. Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection). Also a lovely comune (municipality) in the Province of Ancona in the Italian region of Marche.

    gojq

    gojq

    Pure Go implementation of jq

    This is an implementation of jq command written in Go language. You can also embed gojq as a library to your Go products. gojq is purely implemented with Go language and is completely portable. jq depends on the C standard library so the availability of math functions depends on the library. jq also depends on the regular expression library and it makes building scripts complex. gojq implements nice error messages for invalid query and JSON input. The error message of jq is sometimes...

    Miniredis

    Miniredis

    Pure Go Redis server for Go unittests

    Sometimes you want to test code which uses Redis, without making it a full-blown integration test. Miniredis implements (parts of) the Redis server, to be used in unittests. It enables a simple, cheap, in-memory, Redis replacement, with a real TCP interface. It saves you from using mock code, and since the redis server lives in the test process you can query for values directly, without going through the server stack. There are no dependencies on external binaries, so you can easily...

    mgmt

    mgmt

    Next generation distributed, event-driven, parallel config management!

    Mgmt is a real-time automation tool. It is familiar to existing configuration management software but is drastically more powerful as it can allow you to build real-time, closed-loop feedback systems, in a very safe way, and with a surprisingly small amount of our mcl code. For example, the following code will ensure that your file server is set to read-only when it's Friday. It can run continuously, intermittently, or on demand, and in the first case, it will guarantee that your system is...

    Dockertest

    Dockertest

    Write better integration tests!

    Use Docker to run your Golang integration tests against third party services on Microsoft Windows, Mac OSX and Linux! When developing applications, it is often necessary to use services that talk to a database system. Unit Testing these services can be cumbersome because mocking database/DBAL is strenuous. Making slight changes to the schema implies rewriting at least some, if not all of the mocks. The same goes for API changes in the DBAL. To avoid this, it is smarter to test these specific...

    Go of JSON Web Tokens

    A go (or 'golang' for search engine friendliness) implementation of JSON Web Tokens. Our support of Go versions is aligned with Go's version release policy. So we will support a major version of Go until there are two newer major releases. We no longer support building jwt-go with unsupported Go versions, as these contain security vulnerabilities that will not be fixed. In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for Bearer...

    A Go module datastore and proxy

    Athens provides a server for Go Modules that you can run. It serves public code and your private code for you, so you don’t have to pull directly from a version control system (VCS) like GitHub or GitLab.

Athens is a project building on top of vgo (or go1.11+) trying to bring dependencies closer to you so you can count on repeatable builds even at a time when VCS is down. The big goal of Athens is to...

It has a Jsonnet configuration file that aims to be simpler to write and maintain than using the Gmail web interface, to categorize, label, archive and manage your inbox automatically.

    fgprof is a sampling Go profiler that allows you to analyze On-CPU

    fgprof is a sampling Go profiler that allows you to analyze On-CPU as well as Off-CPU (e.g. I/O) time together. Go's builtin sampling CPU profiler can only show On-CPU time, but it's better than fgprof at that. Go also includes tracing profilers that can analyze I/O, but they can't be combined with the CPU profiler. fgprof is designed for analyzing applications with mixed I/O and CPU workloads. This kind of profiling is also known as wall-clock profiling. If this is the first time you hear...

    Bloom filters

    Go package implementing Bloom filters

    A Bloom filter is a concise/compressed representation of a set, where the main requirement is to make membership queries; i.e., whether an item is a member of a set. A Bloom filter will always correctly report the presence of an element in the set when the element is indeed present. A Bloom filter can use much less storage than the original set, but it allows for some 'false positives': it may sometimes report that an element is in the set whereas it is not. When you construct, you need to...
