data PWarnType #

Type of parser warning. We do classify warnings.

Different application may decide not to show some, or have fatal behaviour on others

Constructors

PWTOther	Unclassified warning
PWTUTF	Invalid UTF encoding
PWTBoolCase	`true` or `false`, not `True` or `False`
PWTVersionTag	there are version with tags
PWTNewSyntax	New syntax used, but no `cabal-version: >= 1.2` specified
PWTOldSyntax	Old syntax used, and `cabal-version >= 1.2` specified
PWTDeprecatedField
PWTInvalidSubsection
PWTUnknownField
PWTUnknownSection
PWTTrailingFields
PWTExtraMainIs	extra main-is field
PWTExtraTestModule	extra test-module field
PWTExtraBenchmarkModule	extra benchmark-module field
PWTLexNBSP
PWTLexBOM
PWTLexTab
PWTQuirkyCabalFile	legacy cabal file that we know how to patch
PWTDoubleDash	Double dash token, most likely it's a mistake - it's not a comment
PWTMultipleSingularField	e.g. name or version should be specified only once.
PWTBuildTypeDefault	Workaround for derive-package having build-type: Default. See https://github.com/haskell/cabal/issues/5020.
PWTVersionLeadingZeros	See https://github.com/haskell-infra/hackage-trustees/issues/128
