var IncludeStackByDefault = false

IncludeStackByDefault is whether to include the stack by default on all errors. This is exported to allow Encore's CI platform to set this to true for CI/CD builds.

var TerminalWidth = 100

TerminalWidth is the width of the terminal in columns that we're rendering to.

We default to 100 characters, but the CLI overrides this when it renders errors. When using the value, note it might be very small (e.g. 5) if the user has shrunk their terminal window super small. Thus any code which uses this or creates new widths off it should cope with <= 0 values.


func AddHintFromGo

func AddHintFromGo(err error, fileset *token.FileSet, node ast.Node, hint string)

func ColoursInErrors

func ColoursInErrors(enabled bool)

func ExtractFromPanic

func ExtractFromPanic(recovered any) error

ExtractFromPanic returns the first ErrInSrc or ErrorList found in the recovered value.

If no value is recovered, then nil is returned.

func Panic

func Panic(list ErrorList)


type Bailout

type Bailout struct {
	List ErrorList

Bailout is a panic value that can be used to

func (Bailout) Error added in v1.9.3

type CharacterSet struct {
	HorizontalBar rune
	VerticalBar   rune
	CrossBar      rune
	VerticalBreak rune
	VerticalGap   rune
	UpArrow       rune
	RightArrow    rune

type ErrInSrc

type ErrInSrc struct {
	// The parameters of the error
	// This is an internal data type to force the
	// creation of these inside `srcerrors`
	Params ErrParams `json:"params"`

	// The Stack trace of where the error was created within the Encore codebase
	// this will be empty if the error was created in a production build of Encore.
	// To populate this, build Encore with the tag `dev_build`.
	Stack []*StackFrame `json:"stack,omitempty"`

ErrInSrc represents an error which occurred due to the source code of the application being run through Encore.

It supports the concept of one of more locations within the users source code which caused the error. The locations will be rendered in the final output.

Construct these using helper functions in the `srcerrors` package as we can use that as a central repository error types
