PlantUml:如何在opt条件下对序列图进行多行显示

Question

我试图在PlantUML中为下面的脚本做一个UML图。

[plantuml, target=diagram-sequence, format=png] 
....
@startuml
-> A: test
opt ((Exterme_DANGER_Forwith_cIES_MICRO_GYRO) || (Exterme_DANGER_Forwith_cIES_PANASONIC_GYRO)  || (Exterme_DANGER_Forwith_cIES_VIRTUAL)    || (Exterme_DANGER_Forwith_cIES_Cobra)     || (Exterme_DANGER_Forwith_cIES_VTI)    || (Exterme_DANGER_Forwith_cIES_VTI_SPI)    || (Exterme_DANGER_Forwith_cIES_VIRTUAL)    || (Exterme_DANGER_Forwith_cIES_VTI)     || (Exterme_DANGER_Forwith_cIES_VTI_SPI)   || (Exterme_DANGER_Forwith_cIES_VIRTUAL))    || (Exterme_DANGER_Forwith_cIES_Cobra5)  || (Exterme_DANGER_Forwith_cIES_Cobra4))
<- A
end opt
@enduml
....

当我这样做时，我看不到完整的图表。

​

有谁知道在图表中用多行表示大选项的方法吗？

Answer 1

添加新行\n将打破图中多行的opt，但它仍然位于PlantUML文本文件中的一个行上，这很难读懂。

为了提高可读性，在行尾添加\将允许跨多行拆分文本。

结合\n和\，可以在图和文件中将单行分割为多行：

@startuml
-> A: test
opt ( \
    (Exterme_DANGER_Forwith_cIES_MICRO_GYRO)       \n\
    || (Exterme_DANGER_Forwith_cIES_PANASONIC_GYRO)\n\
    || (Exterme_DANGER_Forwith_cIES_VIRTUAL)       \n\
    || (Exterme_DANGER_Forwith_cIES_Cobra)         \n\
    || (Exterme_DANGER_Forwith_cIES_VTI)           \n\
    || (Exterme_DANGER_Forwith_cIES_VTI_SPI)       \n\
    || (Exterme_DANGER_Forwith_cIES_VIRTUAL)       \n\
    || (Exterme_DANGER_Forwith_cIES_VTI)           \n\
    || (Exterme_DANGER_Forwith_cIES_VTI_SPI)       \n\
    || (Exterme_DANGER_Forwith_cIES_VIRTUAL))      \n\
    || (Exterme_DANGER_Forwith_cIES_Cobra5)        \n\
    || (Exterme_DANGER_Forwith_cIES_Cobra4)        \n\
)
<- A
end opt
@enduml
