Open Source Go Linters

Container Image Linter for Security, Helping build the Best-Practice Docker Image, Easy to start. You can install dockle with the asdf version manager with this plugin, which automates the process of installing (and switching between) various versions of github release binaries. With asdf already installed, run commands to install dockle. You can scan your built image with Dockle in Travis CI/CircleCI. Though, you can ignore the specified target checkpoints by using .dockleignore file. Or, if you just want the results to display and not let the test fail for this, specify --exit-code to 0 in dockle command.

golangci-lint is a fast Go linters runner. It runs linters in parallel, uses caching, supports yaml config, has integrations with all major IDE and has dozens of linters included. ⚡ Very fast: runs linters in parallel, reuses Go build cache and caches analysis results. Yaml-based configuration. Integrations with VS Code, Sublime Text, GoLand, GNU Emacs, Vim, Atom, GitHub Actions. A lot of linters included, no need to install them. Minimum number of false positives because of tuned default settings. Nice output with colors, source code lines and marked identifiers.

Joker is a small interpreted dialect of Clojure written in Go. It is also a Clojure(Script) linter. Send HTTP requests, read and parse JSON, work with file system, start external processes etc. Checks for syntax errors, function arity mismatches, unresolvable symbols, unused namespaces, vars, bindings and much more. Joker uses .joke filename extension. Normally exits after executing the script, unless --exit-to-repl is specified before --file <filename> in which case drops into the REPL after the script is (successfully) executed. (Note use of --file, in this case, to ensure <filename> is not treated as a <socket> specification for the reply.) Our goal is to be suitable for scripting (lightweight, fast startup). This is something that Clojure is not good at and my personal itch I am trying to scratch. Also, to provide some tooling for Clojure and its dialects. Joker has linter mode which can be used for linting Joker, Clojure and ClojureScript code.

Prototool lets you handle the installation of protoc and the import of all of the well-known types behind the scenes in a platform-independent manner. Standardize building of your Protobuf files with a common configuration. Lint your Protobuf files with common linting rules according to Google' Style Guide, Uber's V1 Style Guide, Uber's V2 style guide, or your own set of configured lint rules. Format your Protobuf files in a consistent manner. Create Protobuf files from a template that passes lint, taking care of package naming for you. Generate stubs using any plugin based on a simple configuration file, including handling imports of all the well-known types. Call gRPC endpoints with ease, taking care of the JSON to binary conversion for you. Check for breaking changes on a per-package basis, verifying that your API never breaks.

The most opinionated Go source code linter. go-critic is a collection of checks that detect style, and performance issues as well as some common programming errors. We provide as many useful checks as possible. We’re prototyping and experimenting here. When specific check implementation is mature and proven useful, propose it’s integration into other linter. If a good checker can’t find a better home, it stays here. Almost 100 diagnostics that check for bugs, performance and style issues. Extensible without re-compilation with dynamic rules. Includes #opinionated checks with very strict and specific requirements. Self-documented: gocritic doc <checkname> gives a checker description. Usage of gocritic: gocritic [sub-command] [sub-command args...] Run gocritic without arguments to get help output.
