Show ParseException

Defined in Data.Yaml.Internal

Methods

showsPrec :: Int -> ParseException -> ShowS

show :: ParseException -> String

showList :: [ParseException] -> ShowS

Exception ParseException

Defined in Data.Yaml.Internal

Methods

toException :: ParseException -> SomeException

fromException :: SomeException -> Maybe ParseException

displayException :: ParseException -> String

prettyPrintParseException :: ParseException -> String

Alternative to show to display a ParseException on the screen. Instead of displaying the data constructors applied to their arguments, a more textual output is returned. For example, instead of printing:

InvalidYaml (Just (YamlParseException {yamlProblem = "did not find expected ',' or '}'", yamlContext = "while parsing a flow mapping", yamlProblemMark = YamlMark {yamlIndex = 42, yamlLine = 2, yamlColumn = 12}})))

It looks more pleasant to print:

YAML parse exception at line 2, column 12,
while parsing a flow mapping:
did not find expected ',' or '}'

textToScientific :: Text -> Either String Scientific

stringScalar :: StringStyle -> Maybe Text -> Text -> Event

Encodes a string with the supplied style. This function handles the empty string case properly to avoid https://github.com/snoyberg/yaml/issues/24

defaultStringStyle :: StringStyle

Since: 0.11.2.0

isSpecialString :: Text -> Bool

Determine whether a string must be quoted in YAML and can't appear as plain text. Useful if you want to use setStringStyle.

Since: 0.10.2.0

specialStrings :: HashSet Text

Strings which must be escaped so as not to be treated as non-string scalars.

Since: 0.8.32

isNumeric :: Text -> Bool

Since: 0.8.32

objToStream :: ToJSON a => StringStyle -> a -> [Event]

Encode a value as a YAML document stream.
