With PR #987 merged,
mathcode blocks can now be used to display mathematical formulae, Based on this work, this PR adds the feature to usechemcode blocks to display chemical formulae. With this PR merged, you can now write something like:Please note that this PR relies on render hook templates, a feature that is available as of hugo 0.93. For users with older hugo versions., the old, now deprecated way of coding a formulae on its own line is still available.
Furthermore, this PR brings in some additions that streamline and ease the use of formulae for technical writers:
When `math' or 'chem' blocks are used on a page, the required scripts are now loaded automatically. There is no need to enable KaTeX and/or ´mhchem´ in the site configuration any more (only when using hugo 0.93 or newer).
Up to now, KaTeX and/or
mhchemscripts were enabled in the sitewideconfigfile. Once enabled, scripts were loaded for all pages, even it there were no formulae present on the page. With this PR in place, activation of scripts is now possible on a per page basis, too, simply by adding attributes in the page front matter:Also, the documentation page in the user guide was adapted in order to reflect the changes introduced with this PR.
