Hello and thanks for a nice plugin. Have an issue when using "plantuml.jar".

From the code:

try:
    output = None
    if use_web:
        output = plantuml_web(uml_path)
    else:
        plantuml_path = os.path.abspath(args.plantuml_path or PLANTUMLPATH)
        plantuml_exec(uml_path, plantuml_path=plantuml_path)
    svg_name = output[0]
    return SVG(filename=svg_name)
finally:

When "use_web" is "false" the output variable will be "None" meaning that there will be an exception on line:

svg_name = output[0]

Suggests that the line above is changed to:

        output = plantuml_exec(uml_path, plantuml_path=plantuml_path)

Hi,

maybe you can help - I get following error:

pip2 install iplantuml
Collecting iplantuml
  Using cached IPlantUML-0.0.3.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-wli4gI/iplantuml/setup.py", line 18
        print(line, end='')
                       ^
    SyntaxError: invalid syntax
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-wli4gI/iplantuml/

I have to use pip2 as I have python3 as well on my system.

This package works great (and is simple) in colab.research.google.com (it's how I'm using it).

But, whenever there's a mistake in the PlantUML source, there's a traceback that is not useful, instead of a helpful error that PlantUML's server is giving.

For example, in the following cell, note is mistyped with a space in the middle: no te which is a syntax error:

%%plantuml

@startuml
Alice->Bob: Authentication Request
no te right of Bob: Bob thinks about it
Bob->Alice: Authentication Response
@enduml

If I try that on the PlantUML server, I see this info:

If I try it in colab, I get this:

---------------------------------------------------------------------------

I did install it with pip but get error:
ERROR:root:Cell magic %%plantuml not found.

If the PlantUML script is the same, there is no reason to refetch or send to the JVM. Add a decorator that caches if the script matches the last one.

Hi，Since Plantuml original exported SVG support，so we could add hyperlink inside the UML rendering，could we change the SVG out put set up to support this features?
Thanks!

Hello,
I am trying to use plantuml in a jupyter notebook (jupyter 6.4.0). iplantuml process the Bob/Alice example fine but it also prints this message just before the svg output:

Writing output for /home/jf/gitCours/MCS_python/jupyter/ada01c00-65da-4b72-8c8d-df573196bc2d.uml to ada01c00-65da-4b72-8c8d-df573196bc2d.svg

It seems that this message is generated by plantweb, when I tested it in command line. I think that iplantuml should not forward this to the output, just the svg. No ?
Below the screenshot of my test.
Regards.

This:

%%plantuml auth

gets an error.

This, on the other hand,

%%plantuml --jar 

@startuml auth
etc.

works, but, the image returned to the notebook by the magic is the temp name, not the given name, resulting in a file-not-found.

Using iplantuml 0.1.1 with jupyterlab 2.2.6 and Python 3.9.5.

when I import in my notebook I get:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-3db08b9b1ba5> in <module>
----> 1 import iplantuml

ModuleNotFoundError: No module named 'iplantuml'

I’m trying to use the !include directive from Colab, and I can’t get it to work. I’ve tried both as a local file in Colab and as a URL from Google Drive, both without success.
I have created a post on the PlantUml Forum, explaining the case.

pypi/warehouse#2381

Errors occured when pip install iplantuml.

Error 1: TypeError

I copied this example from Math in PlantUML

@startuml
Bob -> Alice : Can you solve: <math>ax^2+bx+c=0</math>
Alice --> Bob: <math>x = (-b+-sqrt(b^2-4ac))/(2a)</math>
@enduml

to p.uml

In a JupyterLab notebook, I have this code cell

%%bash
plantweb --format auto p.uml

The generated p.svg does not shows beautiful math, it still shows the AsciiMath code:

But when I changed the code cell to

%%bash
plantweb --format png p.uml

the generated p.png looks beautifully formatted.

The --format auto and --format svg do not correctly format the AsciiMath and jLatexMath code.

following the README to specify a custom jar path on installation I get a 'no such option: --jarpath' error.

the command i used:

pip install iplantuml --jarpath /usr/local/bin/plantuml.jar

Hello,
I have a problem with you'r command, i would like to change the path because i use windows10.
When i try "python setup.py install iplantuml --jarpath /my/custom/path/plantuml.jar" it's return me my command are invalid 'iplantuml" command ?
It's weird because i have clone with no problem the repo :/

I keep getting this error when I try to use iplantuml in jupyter notebook within visual studio code. Can you please tell iplantuml is supported within vs code?

First, thanks for the good work! If find this extension to be a simple yet very useful example of the potential behind Jupyter :)

The current mechanism allowing path customization for the PlantUML .jar file uses an option passed to setup.py at install time. This precludes pip install iplantuml and seems unnecessarily unwieldy to me.

Why not use an age-old but customization-friendly environment variable for this purpose insead? Something like PLANTUML_JAR_FILE would do the trick.

Or maybe the java executable could even be part of the variable (like https://pypi.python.org/pypi/sphinxcontrib-plantuml does it) so it would be more PLANTUML_RUN_COMMAND.

The second option would be extra convenient in situations where the Java binary is not on the PATH. For example my Windows dev box has no JRE installed, but a version of it is bundled with PyCharm: I'd rather not have its java.exe on the PATH but wouldn't mind using it for the specific purpose of running PlantUML, just as the plantuml4idea plugin runs it inside PyCharm (I am fully aware, however, that this is a matter of convenience and consider the ability to customize this of lesser importance than customizing the .jar path).
