File \href{https://github.com/hrbrmstr/htmltidy/issues}{an issue} if there are other \code{libtidy}
|
|
|
|
|
options you'd like supported.
|
|
|
|
|
|
|
|
|
|
It is likely that the most used options will be:
|
|
|
|
|
|
|
|
|
|
\itemize{
|
|
|
|
|
\item{\code{TidyXhtmlOut} (logical)},
|
|
|
|
|
\item{\code{TidyHtmlOut} (logical)} and
|
|
|
|
|
\item{\code{TidyDocType} which should be one of "\code{omit}",
|
|
|
|
|
"\code{html5}", "\code{auto}", "\code{strict}" or "\code{loose}"}.
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
You can clean up Microsoft Word (2000) and Google Docs HTML via logical settings for
|
|
|
|
|
\code{TidyWord2000} and \code{TidyGDocClean}, respectively.
|
|
|
|
|
|
|
|
|
|
It may also be advantageous to remove all comments with \code{TidyHideComments}.
