I would assume that you have a 32-bit Notepad++ (from placement in x86) and you are trying to load a 64-bit plugin.

Programs and their DLLs (a plugin is a DLL) must match in bitness.

@Fruchtzwerg94 Splitting a sequence diagram using newpage does not work, only the first page is visible and exportable.
I dont see any page navigation option in the context menu.
I have version 1.3.0.7

Good catch @sendhilv . For me it looks like an issue with PlanUML itself. Therefore I’ve created this issue. Let’s see what the developers of PlantUML say about it.

Hi @sendhilv ,

after some more investigation it seems like I can already come up with a first solution here. I’ve updated the current implementation to support pages as well. It’s not tested deeply but it’s worth a try. With the latest change you are able to navigate pages like shown here:

It’s not yet released officially so you need download the version to test here:
Added support for multiple pages per document Continuous Integration #63

Would be great if you could do some deeper tests. Please have a look at it and give me some feedback / let me know if it works for you.

Hi all,

with the latest changes, the plugin version 1.4.0.8 is now officially available.
Biggest change is the multi page support:

Also, PlantUML was updated to 1.2022.8, an error message for non UTF-8 documents was added, the file name of generated diagram is shown in the status bar and the plugin colors are automatically updated if Notepad++ colors are changed.

Have fun with it and let me know if there are questions, problems or feedback.

Cheers,
Philipp

Hi - I tried this on a SysML V2 file and got this: Failed to render.jpg

@Andy-Lapping said in [New plugin] PlantUML Viewer:

SysML V2 file

Hi Andy,
obviously the diagram can’t be rendered by PlanUML. Since you are not showing a minimal set of data you want to render, its nearly impossible to say whats the reason for the error.
But a guess from my side: Keep in mind PlantUML is not SysML. Most propably the SysML standard you are talking about is not supported by PlantUML.

For all of you who are interested in: A new version 1.7.0.11 is released and available.

PlantUML version updated to 1.2024.3
Set generation working directory to current file to allow relative includes
SVG.NET library updated to 3.4.7, dependent ExCSS library updated to 4.2.3 to fix SVG export namespace prefix not set accordingly

You can download it at the 1.7.0.11 release or just wait to the next Notepad++ update to get it with the plugin manager.

@Fruchtzwerg94 Great plugin --Thanks! Do you have a suggestion on the best way to set the path to java.exe in a portable copy of npp? That is, the npp-port will be regularly copied to machines that do not access the internet. It would be nice to copy npp-port over along with a jre (maintaining a relative path), and not have to set the jre path in the npp settings after copy.

Hi @XOR_0110 ,

happy to hear you like it.
You are lucky, a few weeks ago, I’ve commited a change where I changed the way Java is detected. Previously, the environment variable was checked only. Since a lot of devices are not set up with the corresponding environment variable (JAVA_PATH), I’ve added a registry detection as well.
It is not officially released yet, but have a look at the following build: PlantUmlViewer/9022421474
If Java is installed, it should be detected automatically by leaving the setting empty.
Let me know if this works for you.

BR, Philipp

@Fruchtzwerg94 I can’t assume java is installed, so I have been copying portable npp with jre in the plugins folder. Then after I have to go into npp plugins settings and tell it jre is in the plugins folder. Would be helpful if there was a way to give the settings a local path starting from the npp portable folder, or from the npp plugins folder.

Hi @XOR_0110 ,

relative paths are possible as well. So for me, the following works: …\Java\jre1.8.0_361\bin\java.exe. The path is resolved relative to the notepad++.exe. So if your Java JRE is parallel to the Notepad++ folder, this should do the trick.

@Fruchtzwerg94 Thanks! That’s exactly what I needed.
