-v0.1 2010/06/23 - - Première version publique sur le CTAN ----------------------------------------------------------------------- -v0.2 2010/08/31 - - Ajout de la documentation en anglais. - - Correction de bugs. - - \printatom est désormais une macro publique. - - Les espaces sont permis dans les molécules. Ils seront - ignorés par défaut puisque les atomes sont composés en - mode math par \printatom - - Une paire de Lewis peut être représentée ":". - - Dans les cycles, une correction de la longueur du trait - déporté des liaisons doubles est fait de telle sorte que si - l'on écrit \chemfig{*5(=====)}, on obtient deux polygones - réguliers concentriques. - - La séquence de contrôle \setnodestyle permet de spécifier - le style des n?uds dessinés par tikz. ----------------------------------------------------------------------- -v0.3 2010/11/21 - - Amélioration de \definesubmol qui accepte les séquences de - contrôle. On peut aussi choisir un alias dont la substitution - est différente selon l'orientation de la liaison qui lui - arrive dessus. - - Le caractère "|" force la fin d'un atome. Si on écrit - "D|ef" alors, chemfig verra deux atomes "D" et "ef". - - Le caractère "#" est reconnu lorsqu'il suit un caractère de - liaison. Il doit être suivi d'un argument entre parenthèses - qui contient l'offset de début et de fin qui s'appliqueront - à cette liaison. - - La macro \chemfig admet un argument optionnel qui sera passé - à l'environnement tikzpicture dans lequel elle est dessinée - - Mise en place de la représentation des mécanismes - réactionnels avec la syntaxe "@{<nom>}" devant un atome où - "@{<nom>,<coeff>}" au tout début de l'argument d'une liaison. - Cette syntaxe permet de placer un n?ud (au sens de tikz) qui - deviendra l'extrémité des flèches des mécanismes. - Le tracé des flèches est faite par la macro \chemmove dont - l'argument optionnel devient celui de l'environnement - tikzpicture dans lequel sont faites les flèches. - - Pour le mécanisme d'alignement vertical via le \vphantom, la - commande \chemskipalign permet d'ignorer le groupe d'atomes - dans lequel elle est écrite. - - La commande \chemname permet d'afficher un nom sous une - molécule. la commande \chemnameinit initialise la plus grande - profondeur rencontrée. - - La commande \lewis a été modifiée de telle sorte que les - dessins des décorations soient proportionnels à 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 à jour du manuel en anglais. - - Ajout de \vflipnext et \hflipnext pour retourner - horizontalement ou verticalement la prochaine molécule. ----------------------------------------------------------------------- -v0.4 2011/03/07 - - chemfig est désormais écrit en plain-etex et donc - utilisable par d'autres formats que LaTeX. - - Un peu plus de rigueur avec les catcodes des caractères - spéciaux, notamment lorsque la commande \chemfig se trouve - dans l'argument de \chemmove, \chemabove, \chembelow, \chemrel. - TODO : faut-il \scantoker l'argument de \chemfig pour être - définitivement débarrassé de ces histoires de catcode ??? - - Correction d'un bug dans le calcul de l'angle des liaisons ----------------------------------------------------------------------- -v0.4a 2011/04/10 - - Correction d'un bug concernant l'argument optionnel en début - de molécule. ----------------------------------------------------------------------- -v0.4b 2011/04/24 - - l'argument de \chemfig est tokénisé avec \scantokens ce qui - rend caduc tout souci de code de catégorie, à part #. - - la commande \setbondstyle permet de définir le style des - liaisons. - - correction de l'affichage incorrect des doubles liaisons dans - les cycles après les commandes \hflipnext et \vflipnext - - correction d'un bug lorsqu'un alias commence une molécule ----------------------------------------------------------------------- -v1.0 2011/06/15 - - les schémas réactionnels sont désormais disponibles. - - \Chemabove et \Chembelow modifient la boite englobante. - - \Lewis modifie la boite englobante - - les macros \chemleft, \chemright, \chemup et \chemdown - affichent des délimiteurs extensibles à gauche, à droite, - au dessus et au dessous d'un matériel. ----------------------------------------------------------------------- -v1.0a 2011/09/18 - - les macros \Lewis et \lewis admettent un argument optionnel - - la macro \setlewisdist règle la distance entre les 2 - électrons ----------------------------------------------------------------------- -v1.0b 2011/11/29 - - la commande \merge est désormais protégée entre - \schemestart et \schemestop contre des définitions par d'autres - packages. - - \box0 est utilisé au lieu du maladroit \unhbox0 ----------------------------------------------------------------------- -v1.0c 2011/11/30 - - la macro \+ n'est plus explicitement écrite - - vérifie que eTeX est le moteur utilisé ----------------------------------------------------------------------- -v1.0d 2011/12/19 - - les cercles des cycles étaient tracés au mauvais moment. La - longueur de la liaison qui les précédait influait sur le - rayon du cercle : \chemfig{-[,0.5]**6(------)} donnait un bug - à l'affichage. ----------------------------------------------------------------------- -v1.0e 2012/01/13 - - la gestion des espaces dans les groupes d'atomes est - désormais plus rigoureuse. Plusieurs bugs ont été - corrigé ----------------------------------------------------------------------- -v1.0f 2012/02/24 - - correction d'un bug avec \definesubmol, les catcodes n'étaient - pas correctement gérés. ----------------------------------------------------------------------- -v1.0g 2012/11/16 - - correction d'un bug dans \CF_directarrow pour faire prendre en - compte le style des flèche par défaut - - correction d'un bug dans \CF_lewisc : la boite *doit* être - composée en dehors de l'environnement tikzpicture pour - éviter nullfont si jamais \printatom ne passe pas en mode - math. - - correction d'un bug dans \CF_chemfigc : si une longueur par - défaut est modifiée par [,<l>] au début d'une molécule - et si des cycles étaient emboités, cette longueur n'était - pas appliquée aux sous-cycles. - - ré-écriture des macros \chemabove et \chembemow pour - prendre en compte le bug (désormais corrigé) dans luatex. - - nouvelle macro \setstacksep qui définit l'espacement par - défaut dans les macros \chemabove et \chembelow. ----------------------------------------------------------------------- -v1.0h 2013/11/28 - - \chemname admet maintenant une version étoilé qui ne tient - pas compte des profondeurs précédentes. - - \CF_dpmax est géré globalement. - - correction d'un bug dans "-U>" : le style de la flèche - n'était pris en compte pour l'arc. - - correction d'un bug dans \CF_directarrow : l'angle de la - flèche n'était pas calculé ----------------------------------------------------------------------- -v1.1 2015/02/13 - - correction d'un bug dans \CF_seeksubmol : la macro - \CF_molecule est dépouillé de son éventuel espace - en première position. - - correction d'un bug dans \CF_arrowf : le nom du prochain - n?ud courant "end@arrow@i" était erroné dans le cas où une - flèche contenait un sous schéma. Ce nom doit dépendre de - \CF_schemenest. - - la jonction entre deux liaisons consécutives dans l'axe peut - être activé avec \enablebondjoin et désactivé avec - \disablebondjoin (préférable, état par défaut). - - \chemfig suivi d'une "*" demande à ce que les liaisons aient - une longueur invariable : la distance inter-atome devient donc - variable. Cette fonctionnalité est désactivé dans les - cycles afin que les polygones soient réguliers. - \enablefixedbondlength permet cette fonctionnalité pour - toutes les macros \chemfig (même non étoilée) tandis que - \disablefixedbondlength le désactive. ----------------------------------------------------------------------- -v1.1a 2015/02/23 - - correction d'un bug dans \CF_grabbondoffset. Si \chemfig est - dans l'argument d'une macro, les # sont doublés par l'action - de \scantokens de la macro \CF_chemfigb et il faut un - argument délimité avant "(" pour absorber tous les #. ----------------------------------------------------------------------- -v1.2 2015/10/08 - - correction d'un bug dans le tracé des liaisons de Cram. - - création de \setangleincrement. - - chargement de "arrows.meta" et définition de la flèche "CF" - basée sur "Stealth" et définie avec \pgfdeclarearrow. - Les anciennes flèches "CF_full" et "CF_half" sont - abandonnées puisque définies avec \pgfarrowsdeclare. - - flèche "-U>" corrigée : le placement des labels est - maintenant correct dans tous les cas. Ainsi : - -U>[<a>][<b>][<d>][r][a] - place le label <a> près du début de la flèche, quels que - soient les signes du rayon r et de l'angle a. - - \chemrel, \setchemrel et \chemsign sont supprimées. - - compatibilité, avec les limitations d'usage, avec la - librairie "externalize" : le \begin{tikzpicture} voit - désormais le \end{tikzpicture} correspondant dans la macro - \CF_chemfigb. ----------------------------------------------------------------------- -v1.2a 2015/10/21 - - erreur de copier-coller dans le code: une adresse url était - malencontreusement présente en plein milieu d'une ligne de - code ----------------------------------------------------------------------- -v1.2b 2015/11/15 - - bug dans \CF_seeksubmol qui laissait "*" dans le flux de - lecture de TeX. Un message d'erreur est également ajouté - en cas de "!" en fin de traitement. - - correction d'un bug dans \CF_setbondangle où l'angle [<:a>] - n'était pas évalué par \pgfmathsetmacro. ----------------------------------------------------------------------- -v1.2c 2015/11/20 - - Correction d'un bug dans \CF_setbondangle : l'angle renvoyé - pouvait être négatif - - Correction d'un bug dans \CF_directarrow : la macro \CF_ifempty - n'est pas correctement développée dans l'argument de - \pgfpointanchor ----------------------------------------------------------------------- -v1.2d 2015/12/01 - - correction d'un bug dans la flèche "-U" - - la version étoilée de \setcrambond dessine les liaisons de - Cram en pointillés sous forme de trait large et non pas sous - forme de triangle. ----------------------------------------------------------------------- -v1.2e 2017/05/20 - - la macro contenant la définition d'une flèche est - désormais "\CF_arrow(<nom>)", ainsi la macro \0 n'est plus - définie par \definearrow - - remerciements rajoutés après une suppression indue, pour ne - froisser aucune susceptibilité ----------------------------------------------------------------------- -v1.3 2018/03/08 - - tous les paramètres sont désormais passés via \setchemfig qui - fait appel à "simplekv". Par conséquent, _toutes_ les macros qui - réglaient des paramètres deviennent obsolètes, à savoir : - \setcrambond, \setatomsep, \setbondoffset, \setdoublesep, - \setangleincrement, \enablefixedbondlength, - \disablefixedbondlength, \setnodestyle, \setbondstyle, - \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle, - \setarrowdefault, \setandsign, \setarrowoffset, - \setcompoundsep, \setarrowlabelsep, \enablebondjoin, - \disablebondjoin et \schemedebug. - et ces macros seront *supprimées* dans une future version. - - la version étoilée "\chemfig*" et les deux arguments optionnels - de la macro "\chemfig[][]" sont également optionnels et seront - *supprimé*s dans une future version afin d'accéder à la syntaxe - \chemfig[clés=valeurs]{code} - - 6 nouveaux paramètres : "lewis radius", "arrow double sep", - "arrow double coeff", "arrow double harpoon", "cycle radius - coeff", "arrow head". - - correction d'un bug dans \CF_parsemergeopt qui dans certains - cas, envoyait vers l'affichage des caractères - - petit toilettage du code - - macro \polymerdelim (non documentée) expérimentale et encore - en phase de tests - - suppression d'un registre d'écriture de fichier ----------------------------------------------------------------------- -v1.31 2018/04/05 - - correction d'un espace indésirable dans \CF_ifnextchar ----------------------------------------------------------------------- -v1.32 2018/08/23 - - définition de \printatom, \CF_begintikzpicture et - \CF_endtikzpicture dans le fichier t-chemfig.tex ----------------------------------------------------------------------- -v1.33 2018/10/31 - - les macros définies par \definesubmol peuvent désormais avoir un ou - plusieurs arguments - - macro \polymerdelim documentée ----------------------------------------------------------------------- -v1.34 2019/02/23 - - bug dans la flèche "<->" corrigé ----------------------------------------------------------------------- -v1.4 2019/04/18 - - corrections de nombreux bugs - - caractère privé "_" et non plus "@" -> modifications à prévoir - notamment dans la doc avec les codes spécifiques aux flèches, ça - risque de couiner sur tex.stackexchange.com - - anciennes macros abandonnées et désormais indéfinies : - \setcrambond, \setatomsep, \setbondoffset, \setdoublesep, - \setangleincrement, \enablefixedbondlength, - \disablefixedbondlength, \setnodestyle, \setbondstyle, - \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle, - \setarrowdefault, \setandsign, \setarrowoffset, - \setcompoundsep, \setarrowlabelsep, \enablebondjoin, - \disablebondjoin et \schemedebug - - l'ancienne syntaxe \chemfig[][]{} est abandonnée et n'est plus - acceptée, désormais c'est - \chemfig[<clés>=<valeurs>]{<code molécule>} - - l'ancienne syntaxe \lewis[<coeff>] ou \Lewis[<coeff>] n'est - plus acceptée au profit de \lewis[<clés>=<valeurs>]
