Tip of the Day Kiosk

JSL to write HTML.

@cbaril requested a slide deck for the JMP Tip of the Day items to run in kiosk mode. The tips are stored in a JMP install directory as HTML files that will display in a browser. Here's some JSL that will create an index.html file to play the tips in a loop. There really isn't much JSL here: load the file names and insert them into an HTML/JavaScript template, write the result to disk and open it in a browser. Most of the magic is in the CSS and JavaScript; Google was my friend. You'll need to adjust the tip of the day directory for your machine. I only tested with FireFox and a couple of other browsers. You can change the 1.5s transition (two places) and the 10s delay (one place, 10000 ms).

If( JMP Version() < "16", Throw( "This JSL needs JMP 16 or greater" ) );

todd = Match( Left( JMP Version(), 2 ),
	"16", "C:\Program Files\SAS\JMP\16\Tip of the Day\",
	"17", "C:\Program Files\SAS\JMP\17\Tip of the Day\",
	"18", "C:\Program Files\JMP\JMPEA\18\Tip of the Day\",
	Throw( "open the jsl and add the tip file location for JMP " || JMP Version() )
);

If( !Directory Exists( todd ), Throw( "Can't find " || todd ) );
todd = Substitute( todd, "\", "/" );
filelist = Filter Each( {f}, Files In Directory( todd ), Ends With( f, ".htm" ) );
filelist = Transform Each( {f}, filelist, "'file://" || todd || f || "'" );

html = Save Text File(
	"$temp/index.html",
	Eval Insert(
		"
<html>
	<head>
