NAME

html - Produce HTML code for Tranquility

SYNOPSIS

html( s )

DESCRIPTION

html() sends the HTML code in the argument string s to the HTML window for Tranquility.

Like other Tranquility functions that create HTML elements, html() opens a new browser window when called if one did not previously exist.

Elements in s will be placed on the HTML page, left to right, top to bottom in order of being called.

RETURN VALUE

html() has no return value.

EXAMPLES

The following example from page 7 of the Tranquility Programmer’s Manual
https://www.cs.drexel.edu/~bls96/tranquility.pdf creates a table of factorials.

fun fact(n) {
     if .n == 0 {
          return 1
     }
     else {
          return .n * fact(.n - 1)
     }
}

fun genfacts(n) {
     var i, ftab

     ftab : alloc(.n)
     i : 0
     loop {
          until .i >= .n
          (.ftab + .i) : fact(.i)
          i : .i + 1
     }
     return .ftab
}

fun filltable() {
     var i, ftab, istr

     html("<center>0)
     html("<table border=1><tr><th>n</th><th>n!</th></tr>0)
     ftab : genfacts(13)
     istr : alloc(12)
     i : 0
     loop {
          until .i > 12
          html("<tr><td>")
          i2s(.istr, .i)
          html(.istr)
          html("</td><td>")
          i2s(.istr, .(.ftab + .i))
          html(.istr)
          html("</td></tr>0)
          i : .i + 1
     }
     html("</table></center>0)
}


fun init () {
     html("<center>")
     button("Make Table", filltable)
     html("<p>Factorials</p>0/center>0)
}
