Flamalyzer - Static code analysis for Flamingo projects

Flamalyzer is a vet-like tool which detects common errors in Flamingo projects.

Installation

go install flamingo.me/flamalyzer@latest

Usage

Flamalyzer [FLAGS] [PATH]

Flags

There are different Flags which can be passed, if no Flags given the Flamalyzer will run in default mode.

--configFolder=[PATH]

To define the path to your config-files, the default is ./.flamalyzer

--configSuffix=[SUFFIX]

To define a string which must occur in the config-files name which should be loaded (useful if you have different files for different use-cases)

--debugFlamalyzer

To enable more information about what's going on in the program. Like info if the given configFolder-Path isn't configured properly.

Run Flamalyzer within vet

go vet -vettool=$(which flamalyzer) [PATH]

Filewatcher

Flamalyzer can be used as external filewatcher to enable error-highlighting in the IDE. Flamalyzer's output matches exactly vet's output, so the filewatcher configuration from vet can be used.

Available Analyses

Dingo: Pointer receiver check

This analysis checks that an inject-function has a pointer-receiver

Dingo: correct interface binding check

This analysis checks that an instance implements the interface it is bound to.

Dingo: proper inject tags check

This analysis checks if the inject tags are used properly.

"inject tags" should be used for annotated injections only (e.g. config), otherwise inject method should be used.

This means:

No empty inject tags
Inject tags can be defined in the Inject-Function or must be referenced if defined outside
They must be declared in the same package as the Inject-Function

Architecture: dependency conventions check

This analysis checks all import statements below the entry path that the provided Group-Conventions are respected.

Configuration example:

entrypaths: ["src/architecture"]
groups:
  infrastructure: ["infrastructure", "interfaces", "application", "domain"]
  interfaces:     ["interfaces", "application", "domain"]
  application:    ["application", "domain"]
  domain:         ["domain"]

Configuration

The Configuration is done via yaml-files.

The files are expected in ./.flamalyzer

The directory can be specified by --configFolder=[PATH]

config.yaml example:

# Config of the Dingo-Analyzer
dingoAnalyzer:
  checkPointerReceiver: false
  checkStrictTagsAndFunctions: false
  checkCorrectInterfaceToInstanceBinding: false

# Config of the DependencyConventions-Analyzer
architectureAnalyzer:
  entryPaths: []
  checkDependencyConventions: true
  groups:
    infrastructure: ["infrastructure", "interfaces", "application", "domain"]
    interfaces:     ["interfaces", "application", "domain"]
    application:    ["application", "domain"]
    domain:         ["domain"]

There is the possibility to filter the files which should be read in.

Use --configSuffix=[SUFFIX] to pass a string which must be part of config-file name.
