Hi Juraj I do not know it on top of my head. I will check ... For example you get a stream in which you can work [[[eval=true stream nextPutAll: '__WfManagedObject comment:__ ' ; nextPutAll: WfManagedObject comment; cr; lf. ]]] Now I would like to get automatically some png.

Hi,

Pillar allows to evaluate a script and use its output instead of the script itself, e.g.,

-=-=-=- [[[eval=true DateAndTime now printString ]]] -=-=-=-

How can I test it in a Pharo image? I tried:

-=-=-=- document := PRPillarParser parse: '[[[eval=true DateAndTime now printString ]]]' readStream.

PRHTMLWriter write: document. -=-=-=-

It returns: <figure><pre><code>DateAndTime now printString</code></pre><figcaption></figcaption></figure>

Then I tried:

-=-=-=- transformedDocument := (PRScriptEvaluator executeOn: (PRCompilationContext withDocument: document withConfiguration: PRPillarConfiguration new)) input.

PRHTMLWriter write: transformedDocument. -=-=-=-

And it returns an empty string. What should I do to be able to obtain an HTML output with the output of `DateAndTime now printString`?

-=-=-=- documentWithImage := PRPillarParser parse: '[[[eval=true ByteArray streamContents: [ :writeStream | PNGReadWriter putForm: World submorphs atRandom imageForm onStream: writeStream ] ]]]' readStream. -=-=-=-

What is the best practice if the evaluated result should be a screenshot?

Thanks! Juraj
