prettyPrintParseException :: ParseException -> String Source #
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 '}'

decodeHelper :: FromJSON a => ConduitM () Event Parse () -> IO (Either ParseException ([Warning], Either String a)) Source #
decodeHelper_ :: FromJSON a => ConduitM () Event Parse () -> IO (Either ParseException ([Warning], a)) Source #
stringScalar :: StringStyle -> Maybe Text -> Text -> Event Source #
Encodes a string with the supplied style. This function handles the empty string case properly to avoid https://github.com/snoyberg/yaml/issues/24
Since: 0.11.2.0
defaultStringStyle :: StringStyle Source #
Since: 0.11.2.0
isSpecialString :: Text -> Bool Source #
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 Source #
Strings which must be escaped so as not to be treated as non-string scalars.
Since: 0.8.32
objToStream :: ToJSON a => StringStyle -> a -> [Event] Source #
Encode a value as a YAML document stream.
Since: 0.11.2.0
