Diagramme de séquence

• Texte en entrée, diagramme en sortie. Le code source est l'unique source de vérité : ce que vous lisez est exactement ce qui est rendu.
• Facile à modifier. Ajustez une ligne de texte plutôt que de déplacer des cadres.
• Itération rapide. Les outils d'aperçu en direct effectuent le rendu pendant que vous tapez, ce qui permet de repérer les erreurs au plus tôt.

Autre style de flèches

• Pour indiquer un message perdu, terminer la flèche avec x
• Utiliser \ ou / à la place de < ou > pour avoir seulement la partie supérieure ou inférieure de la flèche.
• Doubler un des caractères (par exemple, >> ou //)pour avoir une flèche plus fine.
• Utiliser -- à la place de - pour avoir des pointillés.
• Utiliser "o" après la flèche
• Utiliser une flèche bi-directionnelle <->

@startuml Bob ->x Alice Bob -> Alice Bob ->> Alice Bob -\ Alice Bob \\- Alice Bob //-- Alice Bob ->o Alice Bob o\\-- Alice Bob <-> Alice Bob <->o Alice @enduml
