Cannot reproduce the example

[moodymudskipper]

Hi and thanks for the promising package. Unfortunately I can't reproduce the example from the README :

library(plantuml)
x <- '
(*) --> "Initialization"

if "Some Test" then
  -->[true] "Some Activity"
  --> "Another activity"
  -right-> (*)
else
  ->[false] "Something else"
  -->[Ending process] (*)
endif
'
x <- plantuml( 
  x
)

plot( 
  x = x
)
#> Warning in system2(command = java_bin, args = paste(java_opt, cmd,

I see it might be due to java, and ghostscript, but I thought I'd describe the issue as I encountered it before changing anything on my system.

After installing java it still doesn't work but the output is a bit different :

library(plantuml)
x <- '
(*) --> "Initialization"

if "Some Test" then
  -->[true] "Some Activity"
  --> "Another activity"
  -right-> (*)
else
  ->[false] "Something else"
  -->[Ending process] (*)
endif
'
x <- plantuml( 
  x
)

plot( 
  x = x
)

  x, 
  file = "./README_files/test.svg" 
)
#> [1] 1

If I follow the suggestion in the image :

library(plantuml)
x <- "testdot"

x <- plantuml( 
  x
)
plot( 
  x = x,
  vector = FALSE
)

#> [1] 0

This is likely a missing Ghostscript installation. Please check out the PlantUML site for hours to install all the dependencies under Windows.

If that does not help, please report back here.

Thanks.

I installed ghostscript, and also installed graphViz after seeing this :

https://github.com/de-jcup/eclipse-asciidoctor-editor/issues/47

After restarting computer :

library(plantuml)
x <- '

if "Some Test" then
  -->[true] "Some Activity"
  --> "Another activity"
  -right-> (*)
else
  ->[false] "Something else"
  -->[Ending process] (*)
endif
'
x <- plantuml( 
  x
)

plot( 
  x = x

If I do simplify it as suggested :

library(plantuml)
x <- 'Bob -> Alice: Hello!'
x <- plantuml( 
  x
)

plot( 
  x = x
)

I don't know what to more to install from plantUML's website to solve this.

[rkrug]

Have you seen this: https://stackoverflow.com/questions/35256501/windows-rgrimport-ghostscript-error-status-127 ?

I do not have a windows computer at the moment, so I can't try.

Does it work, when you use plantuml from the command line (outside R)?

[moodymudskipper]

I've tried to do : Sys.setenv(R_GSCMD = normalizePath("C:/Program Files/gs/gs9.52/bin/gswin64c.exe")) (that's where my binaries are), and it changes the error for both your first example and my simplified example into :

plot( 
  x = x
)
#> ERROR
#> 3
#> Syntax Error?
#> Some diagram description contains errors
#> invalid character in attribute value
#> attributes construct error
#> Couldn't find end of Start Tag picture line 3
#> Extra content at the end of the document
#> Erreur : 1: invalid character in attribute value
#> 2: attributes construct error
#> 3: Couldn't find end of Start Tag picture line 3
#> 4: Extra content at the end of the document

I've yet to tried through command line

[robozor]

I have this ERROR too. Any help?

invalid character in attribute value attributes construct error Couldn't find end of Start Tag picture line 3 Extra content at the end of the document Error: 1: invalid character in attribute value 2: attributes construct error 3: Couldn't find end of Start Tag picture line 3 4: Extra content at the end of the document

[rkrug]

Can you produce the graph from the command line using plantuml? I do not have a windows computer at hand and I do not see the error on a Mac.

Please check

1. to produce a plantuml graph from the command line, as described on the plantuml website.

If this works, try again fron R. If not, get in contact with the plantuml mailing list for help.

Could you please report back?

Thanks.

[rkrug]

@ambica-aas It seems you have a plantuml problem and not a problem with platuml in R?

If it is actually a problem with the R package plantuml, could you please open a new issue and post some reproducible code?

At the moment, I have no way of knowing what you did and therefore no way of even guessing what the problem is.

Just be aware, this is NOT the plantuml support - that one you can find at PlantUML Forum.

[ambica-aas]

OK, sorry.

[ambica-aas]

I've tried to do : Sys.setenv(R_GSCMD = normalizePath("C:/Program Files/gs/gs9.52/bin/gswin64c.exe")) (that's where my binaries are), and it changes the error for both your first example and my simplified example into :

I've yet to tried through command line

Try parameter "vector = FALSE") plot(x=x, vector = FALSE)

[consultantleon]

I found this issue and using the setting vector = FALSE seemed to solve the issue as @ambica-aas suggested. However I get a code box displayed under the picture with text "## [1] 0" , see picture :

Slowly getting to the point to give up on the idea to use inline plantuml code in R blocks now as I can't get it to display nicely. When I paste the uml on the plantuml site (//www.plantuml.com/plantuml) it displays cleanly without the extra text box...

[rkrug]

Thanks for your patience. I will see if I find some time to look into this next week.

Sorry for they slow responses. Could you please check if the errors still occurs using a release >= v.0.6.5 (from R-Universe at https://rkrug.r-universe.dev/plantuml or github)?

I made major changes in the use of plantuml an the handling of the plantuml graphs.

Thanks.

[moodymudskipper]

Thanks, I am now from a Mac but these work and a plot is displayed :

plot( 
  x = x
)

plot( 
  x = x,
  vector = FALSE
)

They return a path visibly though, should it be invisible ?

The last call fails however:

plot( 
  x, 
  file = "./README_files/test.svg" 
)
#> Warning in file.create(to[okay]): cannot create file './README_files/test.svg',
#> reason 'No such file or directory'
#> Error in read_data(svg): Argument 'svg' or 'css' must be a file path, url, or raw vector.

This also works as intended, I think :

suppressPackageStartupMessages(library(plantuml))
x <- "testdot"

x <- plantuml( 
  x
)
plot( 
  x = x,
  vector = FALSE
)

#> [1] "/var/folders/mp/qvg2y_jx63bgk_s0xxh2zr140000gp/T//RtmpptD7no/plantuml.e73c3ec6ceb8.svg"

^{Created on 2023-01-27 with reprex v2.0.2}

And the Bob/Alice example works with and without vector = FALSE

[rkrug]

Could you please give me a reproducible example, so that we talk about the same "x"?

[rkrug]

Also: the argument vector is not used anymore. I should put in a warning.

[moodymudskipper]

Sure, it was the example from the top post, see below:

suppressPackageStartupMessages(library(plantuml))
x <- '
(*) --> "Initialization"

if "Some Test" then
  -->[true] "Some Activity"
  --> "Another activity"
  -right-> (*)
else
  ->[false] "Something else"
  -->[Ending process] (*)
endif
'
x <- plantuml( 
  x
)

plot( 
  x = x
)

#> [1] "/var/folders/mp/qvg2y_jx63bgk_s0xxh2zr140000gp/T//RtmpYmZxc2/plantuml.ec83443022cc.svg"

[rkrug]

could you try running dir.create("./README_files") before running the example?

[rkrug]

And also:

server_status()
server_info()

So that we see which server is used (should be the web server)

> server_status()
http://www.plantuml.com/plantuml/ 
                                2 
> server_info()
$version
[1] "1.2023.1beta4"

$PicoWebServer
[1] FALSE

$formats
[1] "png" "svg" "txt"

This does indeed remove the warning :

suppressPackageStartupMessages(library(plantuml))
x <- '
(*) --> "Initialization"

if "Some Test" then
  -->[true] "Some Activity"
  --> "Another activity"
  -right-> (*)
else
  ->[false] "Something else"
  -->[Ending process] (*)
endif
'
x <- plantuml( 
  x
)

dir.create("./README_files")

plot( 
  x, 
  file = "./README_files/test.svg" 
)

#> [1] "./README_files/test.svg"

plantuml::server_status()
#> http://www.plantuml.com/plantuml/ 
#>                                 2
plantuml::server_info()
#> $version
#> [1] "1.2023.1beta4"
#> 
#> $PicoWebServer
#> [1] FALSE

OK - I thought that I put in a dir.create() to create the directory - thanks for your help, I will fix this in the next release.
