Summary description: Draw molecules with easy syntax
Announcement text:
chemfig 1.3 * All parameters are now set via \setchemfig{} with <key>=<value> syntax. The following macros, though still working, are now obsolete: \setcrambond, \setatomsep, \setbondoffset, \setdoublesep, \setangleincrement, \enablefixedbondlength, \disablefixedbondlength, \setnodestyle, \setbondstyle, \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle, \setarrowdefault, \setandsign, \setarrowoffset, \setcompoundsep, \setarrowlabelsep, \enablebondjoin, \disablebondjoin and \schemedebug * The starred version "\chemfig*" and the optionnals arguments "\chemfig[][]", though still, working are obsolete. The \setchemfig macro should be used instead. * 6 new parameters: "lewis radius", "arrow double sep", "arrow double coeff", "arrow double harpoon", "cycle radius coeff", "arrow head", all set via \setchemfig * Bugfix in \CF at parse@mergeopt * Code cleaning. * Macro \polymerdelim (undocumented), included in the code: this macro is exprimental and still in test. * No write register allocated by \newwrite
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/chemfig The package’s files themselves can be inspected at http://mirror.ctan.org/macros/generic/chemfig/

chemfig – Draw molecules with easy syntax
The package provides the command \chemfig{<code>}, which draws molecules using the TikZ package. The <code> argument provides instructions for the drawing operation.
While the diagrams produced are essentially 2-dimensional, the package supports many of the conventional notations for illustrating the 3-dimensional layout of a molecule.
The package uses TikZ for its actual drawing operations.
