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
