Another JSXBIN question.

[cbishop01]

Hi all. 

I have a Fit text to Frame script that works great.  However it adjusts the Fonts by .001 increments is there a way to change this to .02?  I know JSXBIN files cannot be edited but can another script running the Bin file override the font size?

Are you talking about script from in-tools?

Try to contact a script author and ask if he can help...

[cbishop01]

I'll contact the author.  I don't want to infringe on his/her work.  Thank you..  and yes this is from in-tools.  Its a great script.

here's my version, but it requires testing

//DESCRIPTION: Fit each text line to the frame width

#target:indesign;
app.doScript(doUndoWrapper, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "Fit text");
function doUndoWrapper()
{
    var pointStep = 2; // pt    
    if(app.selection[0] && app.selection[0].hasOwnProperty("parentStory")){    
        var text = app.selection[0].parentStory;
        if(text.contents.length == 0){
            exit(alert("Empty text frame selected!", "Error", 1));
        }else{
            // replace space to fixed width space (\u202F). 
            // But since fixed width space is non-breakable - we add discretionary line break (\u200B) before and after
            text.contents = text.contents.replace(/ /g, "\u200B\u202F\u200B");            
        }
        app.selection[0].textFramePreferences.firstBaselineOffset = FirstBaseline.CAP_HEIGHT;
        app.selection[0].textFramePreferences.verticalJustification = VerticalJustification.JUSTIFY_ALIGN;
        text.hyphenation = false;
        text.justification = Justification.FULLY_JUSTIFIED;        
        var lines = app.selection[0].parentStory.lines.length;
        for(var i = 0; i < lines; i++){
            // increasing text size till it break to the next line
            while(app.selection[0].parentStory.lines.length == lines){
               app.selection[0].parentStory.lines.pointSize += pointStep;
            };
            // roll back (to the last acceptable text size)
            app.selection[0].parentStory.lines.pointSize -= pointStep;
        }
        app.selection[0].fit(FitOptions.frameToContent);
    }else{
        exit(alert("Select text frame first!", "Error", 1));
    }
}

A generic fit-text-to-frame is reviewed here:

Indiscripts :: InDesign Scripting Forum Roundup #8

It is fast and flexible. Any text property can be made adjustable.

Hi Mark,

The link you provided is pointed to HORIZONTAL TEXT SCALE and here we are looking for text size change (fit text to frame), not horizontal text scale...

And your script seems not working, or I'm doing something wrong - nothing changes, and there are no errors

Hi Oleh,

Sorry, my mistake.

Two changes must be done to use my code:

1. Use 'pointSize' instead of 'horizontalScale' in parameter.

2. Remove the 1 != s.lines.length condition in the wrong() function (in the original script we had to handle single-line frames.)

The final snippet looks like

(function(/*Item[]*/a,/*str*/k,/*uint*/MIN,/*uint*/MAX, /*num*/PRECISION)  
{  
    var t, s, v, w, m = [],  
        wrong = function(){ return +t.overflows };
    while( t=a.pop() )  
    {  
        if( 'TextFrame'!=t.__class__ ) continue;  
        // Init  
        // ---  
        v = (s=t.parentStory);  
        m[0] = MIN;  
        m[1] = MAX;  
        // Try extremum and quit if status doesn't change  
        // ---  
        s = m[1-(w=wrong())];  
        if( w==wrong() ){ s=v; continue; }  
        // Binary search  
        // ---  
        while( m[1]-m[0] > PRECISION ){ m[w=wrong()] = s = (m[0]+m[1])/2; }  
        w && (s = m[0]);  
    }  
})(app.properties.selection||[], 'pointSize', 6, 36, .1);

Does it work better?

Mark, your script works now, but not at the expected way (for me). Seems your script just increase font size to fill the frame with text.

And, personally, I expected to increase each line of text to the frame width, like in a screenshot below...

I think that's what Fit text to frame should do. But looks like your script just do what topic starter was looking for - let's wait and see
