# 100 Facts Quizzer

A Perl module(!) that I wrote in 2004 to give students randomized quizzes over

the web on Java syntax. Questions are based on flexible templates written in

a custom domain-specific language (DSL).

Note that this is eight years before CodeCademy got millions of dollars in

funding for doing the same thing.

Here's an example question template:

```

	$x=$choose(i,j,k,x,y,z,a,b,c,foo,bar,qwerty)

	$val=$irand(-20,20)

	$rel=$choose(<,>,<=,>=,==,!=)

	$desc=$choose_same(less than, greater than, less than or equal to, \

		greater than or equal to, equal to, not equal to)

	$desc2=$choose_same(under, over, at most, at least, the same as, \

		not the same as)

	
Write a boolean expression using one variable.  The question will

	be of the form "...write an expression which is true when <var>

	is <relation> <value> and false otherwise."


	
All variables will be integers.


	
Variants:

	


		
Phrased with the words "less than", "greater than", "less than or

		equal to", "greater than or equal to", "equal to", or "not equal to".

		

Phrased with more obscure words that mean the same thing:

		

		"under"            instead of  "less than"

		"over"             instead of  "greater than"

		"at most"          instead of  "less than or equal to"

		"at least"         instead of  "greater than or equal to"

		"the same as"      instead of  "equal to"

		"not the same as"  instead of  "not equal to"

		

	



	
Examples:



( qwerty <= -18 ) // "...true when qwerty is at most -18 and false otherwise"

( bar != 10 )     // "...true when bar is not equal to 10 and false otherwise"



	
Note that responses without the surrounding parentheses will be counted

	wrong.


	
Write a boolean expression that is true when the variable

	$x is $desc $val and false otherwise.


	( $x $rel $val )

	
Write a boolean expression that is true when the variable

	$x is $desc2 $val and false otherwise.


	( $x $rel $val )

```

Stuff inside the `` tags is HTML and shown to the students when

they're looking at the Study Guide. There's a preamble which randomly chooses

some identifiers and stores them into variables.

Then several `` blocks follow, each containing a different formulation

of the same essential question. Both the question and its answer get to use

the variables from the preamble.

The module canonicalizes their response to ignore syntactically-insignificant

whitespace and such like.
