CTAN update: chemfig

Date: April 19, 2019 10:06:14 AM CEST
Christian Tellechea submitted an update to the chemfig package. Version number: 1.4 License type: lppl1.3c Summary description: Draw molecules with easy syntax Announcement text:
chemfig v1.4 - many bugs are fixed - the private character in the macro name is no longer "@" but becomes "_" and the prefix of private macros is now "\CF_" IMPORTANT: this implies for advanced users who have used private macros to rename them - all old macros obsolete for more than a year are no longer defined and will throw a compilation error if used: \setcrambond, \setatomsep, \setbondoffset, \setdoublesep, \setangleincrement, \enablefixedbondlength, \disablefixedbondlength, \setnodestyle, \setbondstyle, \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle, \setarrowdefault, \setandsign, \setarrowoffset, \setcompoundsep, \setarrowlabelsep, \enablebondjoin, \disablebondjoin and \schemedebug From now on, the macro \setchemfig{<key>=<<values>} should be used to set parameters - the syntax \chemfig*[][]{} is no longer accepted and becomes \chemfig[<keys>=<values>]{<molecule code>} - the syntaxes \lewis[<coeff>]{<code>} and \Lewis[<coeff>]{<code>} are no longer accepted and become \lewis[<key>=<values>]{<code>} and \Lewis[<key>=<values>]{<code>}

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.
