Update Copernicus Publications template to comply with editor’s guidelines following a manuscript bounce back during the typesetting step. Copernicus does not allow to add any
\usepackagecommand as they all are included incopernicus.clsfor supported LaTeX packages. This is leading to breaking changes with existing template - please follow the advice below.-
algorithms: truecannot be used anymore and as no more effect.\usepackage{algorithmic}and\usepackage{algorithm}has been removed from the template as the command are already done incopernicus.cls. Please, make surealgorithmsandalgorithmcxare installed. - Additionally, the template gained support for the
highlightparameter of [rmarkdown::pdf_document()] to enable or disable syntax highlighting with Pandoc. To comply with the above guideline by Copernicus, it is disabled by default (highlight: NULL) to prevent Pandoc adding any more packages required for its highlighting. Syntax highlighting can be reactivating by usinghighlight: "default"in the YAML header as this can be desirable before submitting for typesetting. (thanks, @RLumSK, @nuest, #391).
