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 '}'
