Some users have asked for latex/tikz support.

So here is an beta version that has "-tlatex" flags in its command line.

https://dl.dropboxusercontent.com/u/13064071/plantuml.jar

We have choosen a simple diagram:

@startuml
class Subscriber {
  subscriberId
}
class AccumUsage {
  subscriberId
}
class IpSession {
  ipAddress
  specificData
  sapcOriginStateId
  apnId
}
Subscriber "1" --> "1..*" IpSession
Subscriber "1" --> "0..1" AccumUsage
@enduml


The goal of this test is to generate a tikz file like this :

https://www.writelatex.com/read/pgkkspzgzgpb

\documentclass{article}
\usepackage{tikz}
%
\begin{document}
\begin{tikzpicture}[yscale=-1]
\draw (131pt,29pt) rectangle (223pt,90.8359pt);
\node at (160pt,37.4531pt)[below right]{Subscriber};
\draw (132pt,61pt) -- (222pt,61pt);
\node at (137pt,65pt)[below right]{subscriberId};
\draw (132pt,82.8359pt) -- (222pt,82.8359pt);
\draw (31pt,212pt) rectangle (137pt,273.8359pt);
\node at (60pt,220.4531pt)[below right]{AccumUsage};
\draw (32pt,244pt) -- (136pt,244pt);
\node at (37pt,248pt)[below right]{subscriberId};
\draw (32pt,265.8359pt) -- (136pt,265.8359pt);
\draw (221pt,191pt) rectangle (318pt,294.3438pt);
\node at (254.95pt,199.4531pt)[below right]{IpSession};
\draw (222pt,223pt) -- (317pt,223pt);
\node at (227pt,227pt)[below right]{ipAddress};
\node at (227pt,240.8359pt)[below right]{specificData};
\node at (227pt,254.6719pt)[below right]{sapcOriginStateId};
\node at (227pt,268.5078pt)[below right]{apnId};
\draw (222pt,286.3438pt) -- (317pt,286.3438pt);
\draw (191.942pt,90.081pt) ..controls (205.204pt,115.893pt) and (224.952pt,154.325pt) .. (241.265pt,186.076pt);
\node at (191.0584pt,98.9168pt)[below right]{1};
\node at (230.3817pt,166.6703pt)[below right]{1..*};
\draw (162.058pt,90.081pt) ..controls (145.645pt,122.023pt) and (119.302pt,173.295pt) .. (101.824pt,207.31pt);
\node at (143.0082pt,98.7264pt)[below right]{1};
\node at (101.801pt,187.522pt)[below right]{0..1};
\end{tikzpicture}
\end{document}

 

Works is still in progress...

If this is the place to post bug reports on the Latex/tikz generation, the following simple file (lets call it test.uml) causes a NullPointerException:

@startuml
class Foo
class Bar <|-- Foo
@enduml
 
I am using the following command line: java -jar plantuml.jar -tlatex test.uml. Generating other formates (e.g., PNG) works as expected.
 
I've uploaded the full traceback here: http://hastebin.com/otesifiyil

It's the right place, thanks for the report.
We have solved this bug in the following beta:
https://dl.dropboxusercontent.com/u/13064071/plantuml.jar
Feel free to go on if you find any other issues (we've made almost no tests on the latex export).

I don't know if it's working as intended but when there is special latex character in the plantuml code, the generated latex won't compile.

For example:

@startuml
title any_string_with_underscore
@enduml

It generate :

% generated by Plantuml 8021

(...)
\node at (0pt,0pt)[below right]{any_string_with_underscore};
(...)

So you get an error with pdflatex :

! Missing $ inserted.
<inserted text>
                $
l.6 \node at (0pt,0pt)[below right]{any_
                                        string_with_underscore};
?

If you add backslashs it works (any\_string\_with\_underscore)

Thanks for the feedback, this is a bug.
There is a beta version here that fixes it:
https://dl.dropboxusercontent.com/u/13064071/plantuml.jar

By the way, we are in the middle of something. We'd like to use real guillemot instead of << and >> for rendering.

So with this beta, if you test:

@startuml
title any_string_with_underscore
actor foo << Foo >>
@enduml

You'll see that in the Latex code, we are now using \usepackage{aeguill} and the commands \guillemotleft \guillemotright
Any though about this?

Do not hesitate to post here if you find other issues with Latex : very few tests have been done.

The <<>> replacement looks fine to me, but I know what it is supposed to replace so maybe I'm prejudiced.

Another remark maybe : it would be possible to insert everything into a figure environnement and make the title "any_string_with_underscore" as the caption (maybe with an automatic label) ?

Like this :
\begin{figure}

\caption{\label{fig:plantuml-any_string_with_underscore} any\_string\_with\_underscore}
\end{figure}

I think that in most case you want to export to latex because you will use the diagram in your document and it will be inside a figure and the title of the diagram should be the caption.

 I think resizing the figure would be nice too because rigth now a figure can go way above the limit of the page. Edit : This is not simple at all to do in latex the text does not adapt well when you use scale in the tikz figure, and I don't think there is a simple solution to this.

Hi.

Extending a use case to another use case will generate a solid arrow instead of dashed arrow. My workaround: edit the generated LaTeX code manually by adding "dashed" inside the \draw[...].

Great work by the way. PlantUML really helps me.

Hey,

I cannot run 

plantuml -v -tlatex:nopreamble life-cycle.pum

on this simple diagram. Are you able to reproduce and fix?

The error message is shown below.

Thanks,

Unfortunately, export to LaTeX works only with UML diagrams.
Your diagram is a GraphViz/Dot one.
Sorry about that!

I think I found another bug for the "-tlatex" option. I have created a sequence diagram and some of the text field contain the special LaTeX character "%". This not automatically transformed into "\%".

When I do these changes manually, the *.latex file is build correctly into a PDF by the LaTeX environment.
commented May 23, 2018 by plantuml (294,960 points)
Thanks for the feedback.
This should be fixed in last beta http://beta.plantuml.net/plantuml.jar
Tell us if it's not working for you or if you find other bugs!

Hi!

Thanks for your quick reply!
I used PlantUML 1.2018.6
You're right. This error does not occur with the current PlantUML beta (1.2018.07beta3).

Thank you very much for your great work! Outstanding tool!

Hi and thank you for the great and powerful software!

I think I found a minor bug for the Latex export option. I created a class diagram with the following contents:

@startuml

"HDF5 data file" *-- RSSI

"HDF5 data file" *-- Pilot_Samples

"HDF5 data file" *-- FrameCompleteTime

Pilot_Samples .[#blue].> CSI : samps2csi()

Pilot_Samples .[#blue].> IQ : samps2csi()

class RSSI{

[Frame,User,BS antenna]

15026 x 9 x 96

}

class Pilot_Samples{

[Frame,BS antenna,Samples,I/Q]

15026 x 96 x 2016 x 2

}

class FrameCompleteTime{

256 x 2

}

class CSI{

[Frame,User,LTS1/2,BS ant,Subcarrier]

15026 x 9 x 2 x 96 x 52

}

class IQ{

[Frame,User,LTS1/2,BS ant,Samples]

15026 x 9 x 2 x 96 x 64

}

note "Samples = Samps per user * num of users\n2016 = 224 * 9\nnum of users = actual num + 1 for noise" as N1

Pilot_Samples .. N1

@enduml

The resulting diagram is correct, however the comment box is much wider than the one generated in the PNG image. You can see the difference on this screenshot: https://imgur.com/p6ceLMd

I generate the LaTeX file with

java -jar plantuml.jar -tlatex class.puml

By the way, is there an easy way to import the resulting file in a LaTeX document? So far I have had success by copying only the TikZ picture contents to a figure environment in the target document.

Thank you for your time and efforts!

About font, it's a issue that is impossible to fix...
You can see http://forum.plantuml.net/6495/wrong-class-widths-after-latex-export
The only workaround is to play with a special setting:
skinparam tikzFont 1.2;4.0
Try to slightly change the value to see if it helps

About your other question, you may have a look at http://forum.plantuml.net/4192/please-provide-command-parameter-output-without-preamble
Is this what you are looking for ?
commented Oct 17, 2018 by dando (140 points)
Thank you very much for the fast and accurate response!

I will take a close look at the references and will see if I can tweak the parameters in order to get a properly-sized comment box. This is anyway a minor issue so the diagram is quite usable as-is currently.

The "-tlatex:nopreamble" option works perfectly. I actually found it a tad later after initially posting the question but decided to not edit it.

Thanks again for your time and efforts!! Keep up the great work! :)

Great work. A 'sourcename.puml' should be processed without the surrounding LaTeX controls to enable an input from sourcname.tex into the document.

\documentclass{article}
\usepackage{tikz}
%
\begin{document}
\begin{tikzpicture}[yscale=-1]

\input{sourcename}

\end{tikzpicture}
\end{document}

Hello,
I'm not sure to understand the request.
Could you give more information ?
Thanks!
commented Feb 13, 2021 by Andreas
Not my request originally but I have the same opinion. The output generated by plantuml should only contain the part to be included in a document and not create a full latex document.
commented Feb 14, 2021 by plantuml (294,960 points)

You can use -tlatex:nopreamble to do so. Is this what you are looking for ?

commented Feb 15, 2021 by Andreas
Yes! I was stupid enough to miss that in the man page but it is there.

Thanks a lot and keep up the amazing work

If you use the symbol "~" in a class diagram as you do it by the name of the destructor, then the symbol is at the top of the line and not in the middle.

For example:

@startuml
class Test{
+ ~Test()
}
@enduml

I am not sure to understand your request. Is this a defect issue ?

The last example seems to work for us http://www.plantuml.com/plantuml/uml/SoWkIImgAStDuKhEIImkLWX9BIwfvj9Mg0CnD3IvQhaSKlDIWF80
commented Aug 5, 2019 by anonymous

The problem only occurs when you use the -tlatex flag. In the tikz file, the tilde symbol is generated with the command \~. However, in most fonts used by LaTeX, this symbol is not displayed correctly.

Replacing \~ with {\raise.35ex\hbox{$\scriptstyle\mathtt{\sim}$}} in the tikz file sloves the Problem for me, but I do not know if this works in all fonts and font sizes.
