<p>In this set of assignments, published on <a href="https://weblab.tudelft.nl/cs4200/2021-2022/assignment/87683/view">WebLab</a>, we exercise the disambiguation of grammars following the material of <a href="../lecture/3.html">Lecture 3</a>.</p>
|
|
|
|
<!-- You can make the assignments directly in WebLab, but we recommend following the [instructions](/2021/homework/1-1-b) to set up a Spoofax project to make the assignments in Spoofax. -->
|
|
|
|
<p>The template for the assignments this week is: given this (ambiguous) context-free grammar:</p>
|
|
|
|
<ul>
|
|
<li>
|
|
<p>Show that the grammar is indeed ambiguous by giving a sentence and at least two different left-most derivations for that sentence and the corresponding abstract syntax trees.</p>
|
|
</li>
|
|
<li>
|
|
<p>Disambiguate the grammar using declarative disambiguation rules to indicate the associativity and priority of operators.</p>
|
|
</li>
|
|
<li>
|
|
<p>Transform the grammar to an unambiguous grammar with equivalent abstract syntax trees for sentences.</p>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>We also provide an assignment to exercise disambiguation using layout constraints.</p>
