Does not work, nothing happens when saving

[jon301]

Hi

I'm trying to make this plugin work with the following example :

test.uml

@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml

When I save the file, nothing happens.

For information, when I run the following command in the terminal :
java -Dapple.awt.UIElement=true -splash: -jar .vim/plugged/vim-slumlord/plantuml.jar -charset UTF-8 -tutxt test.uml
This generates test.utxt file correctly containing the ascii output of the diagram.

Do you have an idea what could be the problem ?

[jon301]

For information, when I try to save an empty file in test.uml, I get the following error

Error detected while processing function slumlord#updatePreview[6]..<SNR>202_mungeDiagramInTmpFile[2]..<SNR>202_convertNonAsciiSupportedSyntax:
line    3:
"test.uml" 0L, 0C written

This means that the plugin is well installed and reacts to file saves. But it just can't inline the output inside the file when the syntax is valid (no errors, nothing happens) :/

[smilesun]

Nothing happened as well when I save the file, and I have set let s:jar_path = expand("<sfile>:p:h") . "/../plantuml.jar" to the right path, but still it does not work , I am using Uubuntu 16.04

[dylan-chong]

Can confirm @jon301 's results. @scrooloose Are you still alive?

[mitermayer]

Loooks like this plugging stopped working all the sudden with lastest vim

[kinowarrior]

Not working either :( @scrooloose - thoughts please?

[kinowarrior]

With empty file I see:

Error detected while processing function slumlord#updatePreview[15]..161_mungeDiagramInTmpFile[2]..161_convertNonAsciiSupportedSyntax:

With a valid, populated file nothing happens & no messages available in nvim.

[kinowarrior]

Well, it seems to be creaking along, semi-working & throwing errors at the same time for some diagrams:

[kinowarrior]

Regression of this issue I think.

[kinowarrior]

Hmm, the error messages have stopped appearing. It seems that once the temporary file under eg. /var/folders/w_/lkyx406x43v1_507sn2j31jc0000gn/T/nvimWdTnjz/1.utxt has been created, it becomes stable thereafter.

[mitermayer]

@kinowarrior how did you fix it ? how did you create the above file ?

[Slyces]

For users that might want to use the plugin in the future, it's quite easy to fix it.
You just need to replace the plantuml.jar provided in the repo by the latest version available that you can find on the official website.

Example of results obtained:

[Komar0ff]

@Slyces doesn't work for me (Vim 8.1)

[jeames00]

Same for me, nothing happens when saving a .uml file (either empty or with valid markup). Also no change when replacing the plantuml.jar file with one from the PlantUML website. I'm using Neovim v0.4.4.

[sava-j]

Hello, I also had this problem, but modifying slumlord.vim and changing the way the plantuml jar is invoked solved the problem for me - more precisely, invoking the jar in headless mode (adding "-Djava.awt.headless=true" option). I'll create a pull request and let the author decide whether I missed anything there.

[kdurant]

I encount ths same problem.

@kdurant
For the sake of trying it out, can you please try the forked repo or to apply the linked PR? Hopefully that will solve your problem, too.
