actionlint

CI Badge API Document

actionlint is a static checker for GitHub Actions workflow files. Try it online!

Features:

  • Syntax check for workflow files to check unexpected or missing keys following workflow syntax
  • Strong type check for ${{ }} expressions to catch several semantic errors like access to not existing property, type mismatches, ...
  • Actions usage check to check that inputs at with: and outputs in steps.{id}.outputs are correct
  • Reusable workflow check to check inputs/outputs/secrets of reusable workflows and workflow calls
  • shellcheck and pyflakes integrations for scripts at run:
  • Security checks; script injection by untrusted inputs, hard-coded credentials
  • Other several useful checks; glob syntax validation, dependencies check for needs:, runner label validation, cron syntax validation, ...

See the full list of checks done by actionlint.

actionlint reports 7 errors

Example of broken workflow:

on:
  push:
    branch: main
    tags:
      - 'v\d+'
jobs:
  test:
    strategy:
      matrix:
        os: [macos-latest, linux-latest]
    runs-on: ${{ matrix.os }}
    steps:
      - run: echo "Checking commit '${{ github.event.head_commit.message }}'"

        if: ${{ github.repository.permissions.admin == true }}
      - run: npm install && npm test

Why?

  • Running a workflow is time consuming. You need to push the changes and wait until the workflow runs on GitHub even if it contains some trivial mistakes. act is useful to debug the workflow locally. But it is not suitable for CI and still time consuming when your workflow gets larger.
  • Checks of workflow files by GitHub are very loose. It reports no error even if unexpected keys are in mappings (meant that some typos in keys). And also it reports no error when accessing to property which is actually not existing. For example matrix.foo when no foo is defined in matrix: section, it is evaluated to null and causes no error.
  • Some mistakes silently break a workflow. Most common case I saw is specifying missing property to cache key. In the case cache silently does not work properly but a workflow itself runs without error. So you might not notice the mistake forever.

Quick start

Install actionlint command by downloading the released binary or by Homebrew or by go install. See the installation document for more details like how to manage the command with several package managers or run via Docker container.

go install github.com/rhysd/actionlint/cmd/actionlint@latest

Basically all you need to do is run the actionlint command in your repository. actionlint automatically detects workflows and checks errors. actionlint focuses on finding out mistakes. It tries to catch errors as much as possible and make false positives as minimal as possible.

actionlint

Another option to try actionlint is the online playground. Your browser can run actionlint through WebAssembly.

See the usage document for more details.

Documents

  • Checks: Full list of all checks done by actionlint with example inputs, outputs, and playground links.
  • Installation: Installation instructions. Prebuilt binaries, Homebrew package, a Docker image, building from source, a download script (for CI) are available.
  • Usage: How to use actionlint command locally or on GitHub Actions, the online playground, an official Docker image, and integrations with reviewdog, Problem Matchers, super-linter, pre-commit, VS Code.
  • Configuration: How to configure actionlint behavior. Currently only labels of self-hosted runners can be configured.
  • Go API: How to use actionlint as Go library.
  • References: Links to resources.

Bug reporting

When you see some bugs or false positives, it is helpful to file a new issue with a minimal example of input. Giving me some feedbacks like feature requests or ideas of additional checks is also welcome.

PopularActions is data set of known popular actions. Keys are specs (owner/repo@ref) of actions and values are their metadata.

Functions

func EqualTypes added in v1.6.4 

func EqualTypes(l, r ExprType) bool

EqualTypes returns if the two types are equal.

func LexExpression added in v1.6.1 

func LexExpression(src string) ([]*Token, int, *ExprError)

LexExpression lexes the given string as expression syntax. The parameter must contain '}}' which represents end of expression. Otherwise this function will report an error that it encountered unexpected EOF.

func Parse 

func Parse(b []byte) (*Workflow, []*Error)

Parse parses given source as byte sequence into workflow syntax tree. It returns all errors detected while parsing the input. It means that detecting one error does not stop parsing. Even if one or more errors are detected, parser will try to continue parsing and finding more errors.

func VisitExprNode added in v1.6.1 

func VisitExprNode(n ExprNode, f VisitExprNodeFunc)

VisitExprNode visits the given expression syntax tree with given function f.

Types

type ActionMetadata added in v1.5.0 

type ActionMetadata struct {
	// Name is "name" field of action.yaml
	Name string `yaml:"name" json:"name"`
	// Inputs is "inputs" field of action.yaml
	Inputs map[string]ActionMetadataInputRequired `yaml:"inputs" json:"inputs"`
	// Outputs is "outputs" field of action.yaml. Key is name of output. Description is omitted
	// since actionlint does not use it.
	Outputs map[string]struct{} `yaml:"outputs" json:"outputs"`
	// SkipInputs is flag to specify behavior of inputs check. When it is true, inputs for this
	// action will not be checked.
	SkipInputs bool `json:"skip_inputs"`
	// SkipOutputs is flag to specify a bit loose typing to outputs object. If it is set to
	// true, the outputs object accepts any properties along with strictly typed props.
	SkipOutputs bool `json:"skip_outputs"`
}

ActionMetadata represents structure of action.yaml. https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions

type ActionMetadataInputRequired added in v1.6.1 

type ActionMetadataInputRequired bool

ActionMetadataInputRequired represents if the action input is required to be set or not. https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#inputs

func (*ActionMetadataInputRequired) UnmarshalYAML added in v1.6.1 

func (required *ActionMetadataInputRequired) UnmarshalYAML(n *yaml.Node) error

UnmarshalYAML implements yaml.Unmarshaler.

type AnyType 

type AnyType struct{}

AnyType represents type which can be any type. It also indicates that a value of the type cannot be type-checked since it's type cannot be known statically.

func (AnyType) Assignable 

func (ty AnyType) Assignable(_ ExprType) bool

Assignable returns if other type can be assignable to the type.

func (AnyType) DeepCopy added in v1.6.8 

func (ty AnyType) DeepCopy() ExprType

DeepCopy duplicates itself. All its child types are copied recursively.

func (AnyType) Merge added in v1.6.4 

func (ty AnyType) Merge(other ExprType) ExprType

Merge merges other type into this type. When other type conflicts with this type, the merged result is any type as fallback.

func (AnyType) String 

func (ty AnyType) String() string

type ArrayDerefNode 

type ArrayDerefNode struct {
	// Receiver is an expression at receiver of array element dereference.
	Receiver ExprNode
}

ArrayDerefNode represents elements dereference of arrays like '*' in 'foo.bar.*.piyo'.

func (ArrayDerefNode) Token 

func (n ArrayDerefNode) Token() *Token

Token returns the first token of the node. This method is useful to get position of this node.

type ArrayType 

type ArrayType struct {
	// Elem is type of element of the array.
	Elem ExprType
	// Deref is true when this type was derived from object filtering syntax (foo.*).
	Deref bool
}

ArrayType is type for arrays.

func (*ArrayType) Assignable 

func (ty *ArrayType) Assignable(other ExprType) bool

Assignable returns if other type can be assignable to the type.

func (*ArrayType) DeepCopy added in v1.6.8 

func (ty *ArrayType) DeepCopy() ExprType

DeepCopy duplicates itself. All its child types are copied recursively.

func (*ArrayType) Merge added in v1.6.4 

func (ty *ArrayType) Merge(other ExprType) ExprType

Merge merges two object types into one. When other object has unknown props, they are merged into current object. When both have same property, when they are assignable, it remains as-is. Otherwise, the property falls back to any type.

func (*ArrayType) String 

func (ty *ArrayType) String() string

Note that an error is not cached. At first search, let's say this method returned an error since the reusable workflow is invalid. In this case, calling this method with the same spec later will not return the error again. It just will return nil. This behavior prevents repeating to report the same error from multiple places.

Calling this method is thread-safe.
