`erlfmt_scan` returns `erl_anno:location()` in errors however `erlfmt_parse` mostly returns full `erlfmt_scan:anno()` maps. The errors from the parser also surface in the return value of `erlfmt:read_nodes[_string]`

There was a problem hiding this comment.
ret_err/2 throws a proper erl_anno:location(), not sure if it can be returned by parse_node or if it always returns erlfmt_scan:anno()

erlfmt_scanreturnserl_anno:location()in errors howevererlfmt_parsemostly returns fullerlfmt_scan:anno()maps. (I'm not sure if the parser should/can be changed to also returnlocation()as the code generated by yecc just takes the second element of the token tuple, without any transformation, if it is not anerl_anno:anno()https://github.com/erlang/otp/blob/maint/lib/parsetools/include/yeccpre.hrl#L147) The errors from the parser also surface in the return value oferlfmt:read_nodes[_string]I noticed this via dialyzer when calling
erlfmt_parsedirectly.
