-v0.1 2010/06/23 - - Premi\`ere version publique sur le CTAN ----------------------------------------------------------------------- -v0.2 2010/08/31 - - Ajout de la documentation en anglais. - - Correction de bugs. - - \printatom est d\'esormais une macro publique. - - Les espaces sont permis dans les mol\'ecules. Ils seront - ignor\'es par d\'efaut puisque les atomes sont compos\'es en - mode math par \printatom - - Une paire de Lewis peut être repr\'esent\'ee ":". - - Dans les cycles, une correction de la longueur du trait - d\'eport\'e des liaisons doubles est fait de telle sorte que si - l'on \'ecrit \chemfig{*5(=====)}, on obtient deux polygones - r\'eguliers concentriques. - - La s\'equence de contr\^ole \setnodestyle permet de sp\'ecifier - le style des nœuds dessin\'es par tikz. ----------------------------------------------------------------------- -v0.3 2010/11/21 - - Am\'elioration de \definesubmol qui accepte les s\'equences de - contr\^ole. On peut aussi choisir un alias dont la substitution - est diff\'erente selon l'orientation de la liaison qui lui - arrive dessus. - - Le caract\`ere "|" force la fin d'un atome. Si on \'ecrit - "D|ef" alors, chemfig verra deux atomes "D" et "ef". - - Le caract\`ere "#" est reconnu lorsqu'il suit un caract\`ere de - liaison. Il doit être suivi d'un argument entre parenth\`eses - qui contient l'offset de d\'ebut et de fin qui s'appliqueront - \`a cette liaison. - - La macro \chemfig admet un argument optionnel qui sera pass\'e - \`a l'environnement tikzpicture dans lequel elle est dessin\'ee - - Mise en place de la repr\'esentation des m\'ecanismes - r\'eactionnels avec la synatxe "@{<nom>}" devant un atome o\`u - "@{<nom>,<coeff>}" au tout d\'ebut de l'argument d'une liaison. - Cette syntaxe permet de placer un nœud (au sens de tikz) qui - deviendra l'extr\'emit\'e des fl\`eches des m\'ecanismes. - Le trac\'e des fl\`eches est faite par la macro \chemmove dont - l'argument optionnel devient celui de l'environnement - tikspicture dans lequel sont faites les fl\`eches. - - Pour le m\'ecanisme d'alignement vertical via le \vphantom, la - commande \chemskipalign permet d'ignorer le groupe d'atomes - dans lequel elle est \'ecrite. - - La commande \chemname permet d'afficher un nom sous une - mol\'ecule. la commande \chemnameinit initialise la plus grande - profondeur rencontr\'ee. - - La commande \lewis a \'et\'e modifi\'ee de telle sorte que les - dessins des d\'ecorations soient proportionnels \`a la taille - de la police. ----------------------------------------------------------------------- -v0.3a 2011/01/08 - - Correction d'un bug dans l'argument optionnel de \definesubmol - lorsque celui-ci comporte des crochets. - - Mise \`a jour du manuel en anglais. - - Ajout de \vflipnext et \hflipnext pour retourner - horizontalement ou verticalement la prochaine mol\'ecule. ----------------------------------------------------------------------- -v0.4 2011/03/07 - - chemfig est d\'esormais \'ecrit en plain-etex et donc - utilisable par d'autres formats que LaTeX. - - Un peu plus de rigueur avec les catcodes des caract\`eres - sp\'eciaux, notamment lorsque la commande \chemfig se trouve - dans l'argument de \chemmove, \chemabove, \chembelow, \chemrel. - TODO : faut-il \scantoker l'argument de \chemfig pour \^etre - d\'efinitivement d\'ebarass\'e de ces histoires de catcode ??? - - Correction d'un bug dans le calcul de l'angle des liaisons
