This comes from ruamel.yaml module. I believe "<unicode string>" is
supposed to be the type of the data, not what it is. However, it is
possible to get something a bit more helpful, but it depends on which
parser is used. By default we use the C based parser (aka 'safe'). If
we use the round trip parser, we get this:
ruamel.yaml.scanner.ScannerError: while scanning a simple key
in "<unicode string>", line 84, column 5:
maxItems
^ (line: 84)
This can be enabled by passing '-n' (line numbers) to dt-doc-validate.
Currently, you have have to edit the Makefile to do this. The C parser
is a big difference in speed, so I don't want to change the default.
I can probably work around this and dump the erroring line, but I'm
not sure that's always useful. Many errors are indentation related and
those need some context. Plus just dumping the line can be done easily
with sed:
sed -n ${LINE}p <file>
