Tidiers for a corpus object from the quanteda package

Details

For the most part, the tidy output is equivalent to the "documents" data frame in the corpus object, except that it is converted to a tbl_df, and texts column is renamed to text to be consistent with other uses in tidytext.

Similarly, the glance output is simply the "metadata" object, with NULL fields removed and turned into a one-row tbl_df.
