Answered: GitHub's Camo Aggressive Caching Prevent Diagrams from being Updated in Markdown

Sun, 20 Oct 2024 15:05:01 +0000

I had the same problem in C4-PlantUML that after an PR the ex. Layout.md document (is stored on Github) is not correct updated (and old mages are still drawn based on old C4_*.puml documents).
Based on your found url About anonymized URLs - GitHub Docs I fixed it with curl -X PURGE commands

1) open the non working Layout.md in my browser
2a) (optional open the non working image in a separate tab)
Copy the link of the non working image
2b) purged the cached image with the corresponding curl command `curl -X PURGE https://camo.githubusercontent.com/....` in a shell.
(in my case repeat 2a+2b 10 times manually, but if you have automatic generated UML diagrams, then I assume you can automate this process too)
3) Then I cleaned my local cache too (maybe obsolete)
4) Reloaded the problematic Layout.md and all images are correct displayed.

Changing Font Name of a Spot Letter

Mon, 27 Feb 2023 16:54:47 +0000

Hello!

I was wondering if it's possible to change the font used in the spot letter of a class diagram? Last week I posted a similar question regarding changing the spot background color, font color, and border color. I was directed to using the new <style> features, however I haven't figured out how to use <style> to change the font of the spot letter.

So far, I have tried a couple different variations of using the `fontName` field within the style block. For instance, I have tried both:

<style>
spot{
    FontName: Verdana; 
}

</style>

And

<style>
spot{
    spotClass {
        FontName: Verdana;
    }
}
</style>

Answered: How to change color of single switch diamond in activity diagram

Tue, 22 Mar 2022 15:12:27 +0000

Hello K.,

For that you can use style, but it concerns the two diamonds (the first of the test, and the last of the 'endswitch'), you can not change colour separately, but sequentially, as:

@startuml
<style>
diamond {
  BackgroundColor White/Yellow
}
</style>

start
switch (test?)
case ( condition A )
  :Text 1;
case ( condition B ) 
  :Text 2;

<style>
diamond {
  BackgroundColor palegreen
}
</style>

endswitch

switch (test2?)
case ( condition A2 )
  :Text 12;
case ( condition B2 ) 
  :Text 22;

<style>
diamond {
  BackgroundColor red
}
</style>

endswitch
stop

Enjoy,

Answered: is it possible to make a single object wider/longer in my component diagram

Wed, 22 Dec 2021 22:15:43 +0000

Plantuml sizes a component based on its contents, there is no way to specify size (so the following are clumsy workarounds).

Normally I would do this by including trailing spaces to increase width and blank lines to increase height. Using a monospaced font makes width easier to control (but more granular). (See https://forum.plantuml.net/14765/textarea-in-salt for ideas to wrap this in a simple macro).

component A [
<font:monospace>            </font>
<font:monospace>            </font>
A
<font:monospace>            </font>
<font:monospace>            </font>
]

And here is a bonus idea using raw Graphviz contents to specify a height and width numerically. I'm not sure whether it is worth the deviation from Plantuml syntax - probably not. It would need manual adjustment to fit non-default themes.

component Z [
{{
digraph G {
graph [pad=0]
n [fillcolor=lemonchiffon style=filled margin=0 height=0.4 width=6 shape=plaintext fontname="SansSerif" fontsize=11 label="Some text goes here"]
}
}}
]

Cannot easily customize note on class members

Sun, 12 Sep 2021 05:18:44 +0000

It appears customization of notes on class members is currently limited. In particular, you cannot specify the background colour for the note using the "standard" syntax:

note left of class_name::member/' cannot specify color anywhere on this line '/
    this is a note
end note

You can instead customize a floating note and then attach it to the class attribute. It works but often changes the layout in unusual ways. Using the [hidden] connector between the classes is not always successful.

I (mis?)understand from the history that this feature is still a work in progress. Can we have a cleaner and more consistent syntax for this?

Please see the example here: http://www.plantuml.com/plantuml/uml/SoWkIImgAStDuKhEIImkLeY0qf5GEWfAEq9f9oZjp0LbkENdArHpAG11Kc8HLoqNLuI2JOskBaWSneo4CQ9W34SOmmdA09cNbr-Igf1OhE1dgA0Sd5tfb5EQ2ZQt92EpM0684XL0AhXIyr8W32wWGZqza4LMLY2x7O0oG8y00000

Answered: how to make multiple @startuml@enduml blocks (in 1 file) generate into one diagram

Mon, 21 Jun 2021 19:58:57 +0000

Hello A.,

If you have only several @startuml/@enduml (no other diagram type), you could add on the beginning of the file, for a first diagram, this definition:

@startuml
'Change only this value depending of the number of @startuml/@enduml on the full file
!$max=3
!$i=1
label l [
!while $i < $max+1
  {{
  !include %filename()!$i
  }}
  !$i = $i +1
!endwhile
]
@enduml

Here is a full example, for a file named "filename.pu":

@startuml
'Change only this value depending of the number of @startuml/@enduml
!$max=3
!$i=1
label l [
!while $i < $max+1
  {{
  !include %filename()!$i
  }}
  !$i = $i +1
!endwhile
]
@enduml

@startuml
title AAA
a -> b
@enduml

@startuml
title BBB
[c]
@enduml

@startuml
title CCC
[A] lasts 4 days
then [B] lasts 2 days
@enduml

Then you observe the expected result: all diagrams of the file on the first output image (on the first image named 'finame.png' ).

If that can help,
Regards,
Th.

Arrow head style (in a sequence diagram)

Tue, 27 Oct 2020 08:05:54 +0000

Is it possible to change the size (and style) of the arrow head in a sequence diagram? I know I can use different connection types to change the arrow head, but I'm thinking more in line of reducing the "width" of the arrow head.

Answered: maxAsciiMessageLength dosn't work

Tue, 06 Oct 2020 07:02:01 +0000

All those settings are not very consistent, and we should probably implement something easier to understand, but there is a maxMessageSize setting :

Answered: What do the numbers 25 and 45 represent after round Corner? Like what is the range and what do larger numbers mean?

Mon, 31 Aug 2020 13:13:34 +0000

To add to The-Lu's great visual answer with some extra technical detail for SVG format.

If you use that example SVG picture: http://www.plantuml.com/plantuml/svg/VT91oeGW5C3nlQSGJw1Ft4N4zvr4J6AeT7ZPQfYxZsdI39YkYl_l2JqQjg0nxEj2jldXdXhrIl-qcIVqknkDNppIWDfjCLaNo1T3Qu9sqsBfYz1uqiI_HsUnwz3mlgV7uRK8PuHQ57bKr2TpX6gKESfgL3cgQXJyg89N8wG8ARu9kJwSnKVsytuDKixYJUScxWmK0_T6S9QDQ5rK43IGB4Wsa2f8DP3WKPMztIee2f8Qh1lZd_O1

Then a modern browser (I tried Edge and Opera) will let you right-click and 'inspect element'. You can then highlight the different 'rect' components in the text sidebar and it will highlight the rectangle it refers to in the graphic. You'll see that the rects with rounded corners have parameters 'rx' and 'ry' that are both set to half the roundCorner value. rx and ry define the radii of an ellipse at the corner - and since both are set the same you get a circle (until you max one out). The value is an absolute amount (as opposed to being relative to the shape size) and I think the default unit for svg is pixels. The maximum meaningful size for rx is half the width of the rectangle at which point you get no straight line part. Similarly for ry and the height.

Take the "roundCorner 50" example:

rect[Attributes Style] {
fill: rgb(254, 254, 206);
filter: url(#fi4dkuyxad8cj);
height: 52.5938;
rx: 25;
ry: 25;
width: 132;
x: 7;
y: 233;
}

rx and ry are set to half of 50. Since that is almost exactly half the height , you get no perceivable straight line at the sides.

A new syntax for Entity-Relationship (or Information Enineering) ERD diagrams

Tue, 19 Mar 2019 10:30:17 +0000

I would like to point there's already some kind of "textual representation" for ER that could have been ported to PlantUML. I have found a comprehensive document about it. In short, it could have been like this:

@startuml

' __ could signal the Primary Key (just a suggestion)

entity Bus (__reg_no, make, size, deck, no_of_pass)
entity Route (__route_no, avg_pass)
entity Driver (__emp_no, name, cell)
entity Stage (__stage_no)
entity Town (__name)

Bus m..1 Route : is serviced by
Route 1..m Stage : comprises
Driver m..1 : is allocated to
Stage n..m Town : Passes-though
Route n..m Town : Passes-though

@enduml

Which is more readable than the cryptic }|-|| (which is related to the drawn symbols, I know).
Also, the attributes can be written in a more classical way, less "java-ish", as shown in the entities declarations. I.e., the "Bus" entity would be shown as:

If attributes are listed and not hidden (`hide attributes`, i.e.) they could be also drawn following the ERD stadard, UseCase-like oval surrounding their entity, something like this:

NOTE: Since I used a Use-case diagram, I couldn't add the ERD symbols to the line ends.

And, just for completeness and drive the developers crazy, declare the relationships as diamonds if declared:

skinparam erdModel chen

etc.

But, just a thought. Document the current implementation would be nice enough. O:)

Answered: How can I tag classes then show only classes bearing given tags in a class diagram?

Fri, 02 Mar 2018 08:38:53 +0000

We could extends the syntax of the hide/show syntax to hide by default all created classes/interface/enum/annotations.

This is not implemented yet, but imagine a new "hide everything" feature that would by default hide every classes/interface/enum/annotations created.
You would have to declare classes you want to show (in your !include file of each classes).

So something like:

@startuml
hide everything
class foo1
show foo1
class foo2
show foo2
' foo3 and foo4 are not explicitely shown, so they would be hidden.
foo3 --> foo4
@enduml

would only show foo1 and foo2.

Would this suit your needs ?

Answered: Break in while loop renders incorrectly

Tue, 27 Feb 2018 18:42:58 +0000

Thanks for your report.

The fact is that this "break" feature is still beta and was only implemented for "repeat" loop (and not "while" loop).

Anyway, adding this feature to while loop was not so hard, so we did it in last beta http://beta.plantuml.net/plantuml.jar

We've upgraded the online server so your example is working now (use ctrl-F5 to force cache reload) http://www.plantuml.com/plantuml/uml/HSun3i8m30NGtQVmc5wX5Q8IB2nCN20bloGYJQhQLSNjSLXOREdxIT-ZgDzqNp8TCMMucx3d4q_dZfEm-q0wOkwlbQKkq9ZAQx0WpKq6aq-J6b7-zW7HUmreRjhWtxQH1UnARG0bf9bi_XgflsJumliwa6XTQRIB_VC5

However, do not expect too much on this feature. It will work on simple case, but will fail on complex ones.

So we are interested in feedback!

Answered: Use TikZ styles

Tue, 10 Oct 2017 11:14:46 +0000

This sounds like a good idea but this is difficult to implement right now.
'Drawing' in PNG/SVG/EPS/TikZ is done by a low-level generic layer that has no idea about style/class/package/label

However, it would be possible to detect duplicated commands like \draw[color=plantucolor0002,line width=1.5pt] and to generated dedicated style for them (but that would have generated names like aid23sdh) and then have:

\begin{tikzpicture}[yscale=-1,
aid23sdh/.style={color=plantucolor0002,line width=1.5pt}
]
\draw[aid23sdh] (30pt,32pt) rectangle (481pt,341pt);

would this fits your needs ?

Note that this needs some work...

Answered: Wrong class widths after LaTeX export

Fri, 29 Sep 2017 13:30:19 +0000

This one is very difficult to solve.
Because box width are computed in Java using standard Java font.
And drawing is done by LaTeX using LaTeX font, which means that size does not match between both.

However, we've made few tests. We've written some heuristic which tries to guess how the font will size in LaTeX.

You can use beta 18 to check it:

Unfortunately the result will never be perfect here.

Ok. Nice idea!

In last beta https://www.dropbox.com/s/koo42q3d9gxw288/plantuml.jar?dl=0

we've added a flag -pipeimageindex N in the command line, so you can now have:

java -jar plantuml.jar -pipeimageindex 1 -pipe < test.txt

(the index starts at 0).

Is this what you are expecting ?

Answered: Please provide a skinparam to change the border style of a rectangle

Sat, 10 Jun 2017 07:01:00 +0000

Right now, you cannot define dashed rectangle. This only applies to links.

The only setting available beside colors is "round corner".

Working example:

@startuml
skinparam rectangle {
    BorderColor Blue
    BorderColor<<Software System>> Green
    RoundCorner<<Software System>> 25
}
rectangle rect1<<Software System>>
rectangle rect2

rect1 -[dashed]-> rect2

We might improve this in the future, but it's difficult to find a nice syntax. Ideas welcome!

Answered: Please provide a macro to access the PlantUML version

Mon, 29 May 2017 12:55:43 +0000

It's not possible in official release, but in last beta:

https://www.dropbox.com/s/koo42q3d9gxw288/plantuml.jar?dl=0

You can have:

@startuml
title this is %PLANTUML_VERSION%
alice -> bob : hello
!if %PLANTUML_VERSION% > 1201713
alice -> bob : A
!else
alice -> bob : B
!endif
@enduml

Unfortunately, this is not working with "old" release.

Thanks for the suggestion!

Answered: Please provide a macro to access the last modification date of the diagram source file

Sorry, you have to be more specific in your request: I am not sure to understand it fully.

Today, you can print the current version of PlantUML:
@startuml
version
@enduml

Or using the preprocessor ( http://plantuml.com/preprocessing ), you can also have:

@startuml
header generated at %DATE%
Bob -> Alice : hello
@enduml

Is this what you are expecting ?
Thanks!

Answered: Please provide nodes to represent queues and topics

Thu, 20 Apr 2017 07:12:16 +0000

With last beta
https://www.dropbox.com/s/koo42q3d9gxw288/plantuml.jar?dl=0

You can have:

@startuml
queue queue
pipe pipe
@enduml

Hope this helps!

Please add binary signals, compact format, dirac pulses, decimal events and steps bigger than one to Timing Diagram

Fri, 14 Apr 2017 13:06:55 +0000

I played a bit with timing diagrams and found several limitations.

Here they are :

how to draw binary signals ? (1 bit bus)
how to draw in a 'compact format (name of the signal + waveform on the same line) ?
how to draw 'dirac' pulses (typically an interrupt, very small compared to the other signals)
how to make the timeline more flexible :
allow decimal events (@1, @1.1)
allow steps bigger than one (graduation 10-20-30...up to 100 would give 10 graduations. Currently it gives 100 graduations, not readable)
allow non linear scale (10-20-30 ... 100 : 4 graduations with '...' between 30 and 100)

I suppose this list is not enough but if you are interested I can elaborate a bit more

Thanks,

Benoit

Please provide a skinparam to set the background color of the activity beta diamond node

Wed, 12 Apr 2017 17:25:07 +0000

I'd like a skinparam to set the background color of the activity beta diamond node.

It currently is the same as the skinparam activityBackgroundColor, but we normally use Yellow for the conditions, and another color for the actions.

Please allow to set sequence diagram groups color to transparent

Mon, 03 Apr 2017 10:27:48 +0000

Please allow to set sequence diagram boxes color to transparent, currently skinparam SequenceGroupBodyBackGroundColor transparent doesn't work.
