allow new line when writing mermaid

flowchart TB
  a["Proin_elementum_magna"] --> b["quis_enim_porta_congue<br>Orci_varius_natoque"] \
  c["penatibus_et_magnis_dis"] -->                                                  \
  e["parturient_montes_<br>                                                         \
     nascetur_ridiculus_mus.<br>                                                    \
     Vivamus eu_eros vitae<br>                                                      \
     risus_fringilla_sagittis."]

Today we have to write

flowchart TB
  a["Proin_elementum_magna"] --> b["quis_enim_porta_congue<br>Orci_varius_natoque"]  c["penatibus_et_magnis_dis"] --> e["parturient_montes_<br> nascetur_ridiculus_mus.<br> Vivamus  eu_eros vitae<br> risus_fringilla_sagittis."]

"\" to continue line could be a good solution

[lenicyl]

you can use \n instead of <br>

[LuisBL]

you can use \n instead of <br>

The request here is not to have new lines in mermaid rendering but to allow to have some \ line continue writing the source coden to have a more easy to read code

[jgreywolf]

You could always do something like this:

flowchart TB
  a["
  Proin_elementum_magna"] --> b["
  quis_enim_porta_congue<br>Orci_varius_natoque"]  
  c["
  penatibus_et_magnis_dis"] --> e["
  parturient_montes_<br> nascetur_ridiculus_mus.<br> Vivamus  eu_eros vitae<br> risus_fringilla_sagittis."]

Now that I am re-reading this - I am confused. Where are you creating diagrams that you need to do everything on one line? Because this:

flowchart TB
  a["Proin_elementum_magna"] --> b["quis_enim_porta_congue<br>Orci_varius_natoque"]
  c["penatibus_et_magnis_dis"] -->                                                 
  e["parturient_montes_<br>                                                        
     nascetur_ridiculus_mus.<br>                                                   
     Vivamus eu_eros vitae<br>                                                     
     risus_fringilla_sagittis."]

Works fine

It seems that sequence diagram notes is one place where newlines can't be used within quotations.

What works:

sequenceDiagram
    participant A
    participant B

    Note over A: Required variables: <br/> source id <br/> target id <br/> user <br/> group <br/> origin
    A->>B: make_request()

What I'd actually like to use:

sequenceDiagram
    participant A
    participant B

    Note over A: "
      Required variables: <br/>
      source id <br/>
      target id <br/>
      user <br/>
      group <br/>
      origin"
    A->>B: make_request()

I love the idea of mermaid diagrams - to have easily editable graphical content within markdown documentation. However, not being able to use line breaks in the source code makes any diagram that's a bit more complex very hard to read and manage, which kind of beats the original purpose.
