Diagnostic

pub(all) struct Diagnostic {
  code : String
  kind : String
  severity : Severity
  title : String
  message : String
  span : @moonrockz/gleam-parser/span.SrcSpan
SrcSpan
  labels : ArrayView[Label]
  text : String
  hint : String?
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

A problem found while scanning or parsing, in the Gleam compiler's shape: a title ("Syntax error"), a primary span with its message (the compiler's label text), extra labels, and an optional hint. code is one of codes().

Diagnostic::Diagnostic

source

#alias(new, deprecated="Use `Diagnostic(...)` instead")
fn Diagnostic::Diagnostic(code~ : String, severity~ : Severity, title~ : String, message~ : String, span~ : @moonrockz/gleam-parser/span.SrcSpan
SrcSpan, kind? : String, labels? : Array[Label], text? : String, hint? : String?) -> Diagnostic

Create a diagnostic with no extra labels, body text or hint by default.

test {
  let d = @diagnostic.Diagnostic(
    code="GL-SCAN-001",
    severity=Error,
    title="Syntax error",
    message="I don't know what this character means",
    span=@span.SrcSpan::from_ints(2, 3).unwrap(),
  )
  debug_inspect(d.is_error(), content="true")
  debug_inspect(d.labels.length(), content="0")
}

Diagnostic::is_error

source

fn Diagnostic::is_error(self : Diagnostic) -> Bool

Label

source

pub(all) struct Label {
  span : @moonrockz/gleam-parser/span.SrcSpan
SrcSpan
  text : String
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

A span with the text the compiler shows under it.

Severity

source

pub(all) enum Severity {
  Error
  Warning
} derive(Eq, Hash, @moonbitlang/core/debug.Debug
Debug)

How serious a diagnostic is. A file with an Error is rejected; a Warning does not stop parsing.

codes

source

fn codes() -> ArrayView[String]

Every diagnostic code, in table order.

description

source

fn description(code : String) -> String?

The one-line description of a code, or None for an unknown code.
