Extracting JSL code from a journal

MFVIT — Mon, 18 Sep 2017 18:26:22 GMT

Hello!

Does anyone know how to ‘extract’ the JSL code of a given journal? It would be very useful to learn how to write JSL codes that generate reports/journals.

For example suppose you create a journal by adding text, file reference etc.. You want to save the script that would generate that journal. Is that possible?

Many thanks,

Marcello.

Sounds like you want something like this:


x = Current Journal(); // makes a new journal if none open

x << append( // add to the end of the journal

   Outline Box( "example", 

      V List Box( // the outline holds a vertical list of two items...

         Text Box( "hello" ), 

         Button Box( "there", Print( "run some JSL" ) ) 

) ) );

JMP has both .JSL and .JRN files and the contents of them looks similar, but only the .JSL files really have executable script language. The .JRN files have a description of what the JMP output looked like when the journal was created by journalling a platform's output. Except, as you've noticed, journals sometimes have buttons that have scripts that run when the button is pressed.

Or maybe you don't want a journal at all. You can also build complicated displays in a new window.

From the scripting index, this display only has one item:


g = Graph Box(

  Frame Size( 300, 300 ),

  Marker( Marker State( 3 ), [11 44 77], [75 25 50] );

  Pen Color( "Blue" );

  Line( [10 30 70], [88 22 44] );

);

New Window( "My Window's Title", g );

Thank you for you quick response. Suppose I have the journal corresponding to the jsl reported below and I save it as a jrn file. Can I get the jsl code starting from the jrn file? From an open report I can generate the jsl code that produces that report so I was wondering if that is possible also for an open journal. I think my view is too simplistic!! I am starting up with jsl.

Many thanks.

Journals created from JMP platforms do have a copy of the script would reproduce the platform if the data table was available. But journals created from your own scripts (like the earlier example) do not contain a copy of the script that made the journal. But a journal with buttons that run scripts does contain the button scripts.

The original purpose of a journal was to keep a record of the results of running a platform. Mostly the journal is a set of instructions (not JSL) for rebuilding the appearance of the platform without re-running the platform.

But because the platform's red-triangle menu is saved to the journal, the script for re-running the platform is in the journal.

What do you want to do? I think there is a better approach than "undoing" a journal, but I'm unclear on the goal.

Hello Craig,

Thank you very much for your clear explanation of how journals work in JMP. I am creating an add-in and I wanted to learn how to write the jsl code that makes the text appear on two columns. From your response to my other question I solved the problem.

Marcello.
