The following error occurs.

Error: [email protected] postinstall: `npm run getpuml && node scripts/get-vizjs.js`
Exit status 1

I set the version of node-plantuml to 0.9.0 in the package.json dependencies as fine.

Problem

UML diagrams are not shown (seems as broken link) on localhost serving (http://localhost:4000/) by npx honkit serve.
This is happen at the second time to run npx honkit serve, without deleting any generated directories or files.

Reproduce process

In the root dir of some Honkit's contents repository, emulating a "just after cloning" condition.

$ git clean -f
$ npm install
$ npx honkit serve

No problem is found until here. (All UML diagram are shown at http://localhost:4000/ )

Enter CTRL+C to stop serving process, then:

$ npx honkit serve

Access http://localhost:4000/, this problem happens.

Additional Info

• When the first time to run npx honkit serve, _book/assets/images/uml dir is created and images are copied.
• When the second time to run npx honkit serve, _book/assets dir is deleted automatically and not created.
• $repository_root/assets/images/uml dir and the generated images are remains.
• The same problem are happen for running npx honkit build twice.
• When I delete $repository_root/assets/images/uml manually and run npx honkit serve, the problem was fixed temporary.

Currently the generated image is pixelated on retina displays.

The puml file contain Chinese words then this plugin can not work fine.

In our documentation build system we are using Honkit with your plugin.
We tried to use [!include] directive
The files we tested are as follows.

test.md

@startuml
!include test.pu
@enduml

test.pu

@startuml
interface List
List : int size()
List : void clear()
List <|.. ArrayList
@enduml

The generated svg resulted in an error.

I wonder if you still support this plugin and could fix this issue. Or could give us a tip how to fix it.

Related to #7

When markdown files contains multiple UML diagram, some image links in built HTML are broken and these diagram image is not shown in HTML.
More details, the link for UML defined in the FIRST position in markdown file is OK, but the others are always broken.

After building I checked the assets/ directory and I confirmed all images are generated, but only ONE image was copied into _build/assets/ directory.

see honkit/honkit#142 (comment)

Probably, gitbook-plugin-uml generate *.svg on finish:before.
However, HonKit copy resources on generateAssets.

There seems to be a plan to fix it as follows.

Generate *.svg on page:before and it will fix this issue?

Either way, it seems that the timing must be before generateAssets.

When I first typed

gitbook install

I got

after I triggered the command the second time, the error gone. However I got another eror when build pages:

Here my gitbook version:

➜  pedia git:(refactor_tmp) ✗ gitbook --version
CLI version: 2.3.0
GitBook version: 3.2.3

MacOS latest
Node latest

The uml is v 1.0.1

The package being published does not include #9.

https://www.npmjs.com/package/gitbook-plugin-uml

Would you update npm package?

In our documentation build system we are using Gitbook with your plugin.

Most of the time we worked with embedded UML, which worked as a charm.
Recently we tried to use this approach:

{% uml src="test.plantuml"%}{% enduml %}

and Gitbook failed with the Error: ENOENT: no such file or directory, open 'test.plantuml' which is strange cause file was in the same folder as markdown that used it.

After short investigation I realized that plugin is trying to find this file not in the same folder with markdown file, but in the root of Gitbook working directory. Which is wrong, in my understanding, and changes the standard way of attaching assets in Gitbook.

I wonder if you still support this plugin and could fix this issue. Or could give us a tip how to fix it.

In v0.1.10, that's all ok.
In v0.1.11, it has broken image link.

reproduction

1. git clone https://gist.github.com/a7088b874a7055e0f8b5fc2dcbf0131e.git
2. cd a7088b874a7055e0f8b5fc2dcbf0131e
3. gitbook install && gitbook serve
4. Open http://localhost:4000
5. It has broken image link

Problem

Honkit shows following error if you write markdown code block with language uml / puml / plantuml inserting spaces between ``` and uml / puml / plantuml

could not find the language 'uml', did you forget to load/include a language module?
Error: Unknown language: "uml"

Reproduce process

Building following code reproduces the problem

``` uml
@startuml
actor -> (usecase)
@enduml
```

node-plantuml accesses sourceforge, but in my environment, access is restricted.
However, this seems to be solved in 0.7.0.

markushedvall/node-plantuml#20

Please update node-plantuml to 0.7.0.
