<h1 class="top">Syntax tree - strict mode</h1>

<p>This chapter presents the Camlp5 syntax tree when Camlp5 is installed
  in <em>strict</em> mode.</p>

<div id="tableofcontents">
</div>

<h2>Introduction</h2>

<p>This syntax tree is defined in the module "<tt>MLast</tt>" provided
  by Camlp5. Each node corresponds to a syntactic entity of the
  corresponding type.</p>

<p>For example, the syntax tree of the statement "<tt>if</tt>" can
  be written:</p>

<pre>
  MLast.ExIfe loc e1 e2 e3
</pre>

<p>where "<tt>loc</tt>" is the location in the source, and
  "<tt>e1</tt>", "<tt>e2</tt>" and "<tt>e3</tt>" are
  respectively the expression after the "<tt>if</tt>", the one after
  the "<tt>then</tt>" and the one after the "<tt>else</tt>".</p>

<p>If a program needs to manipulate syntax trees, it can use the nodes
  defined in the module "<tt>MLast</tt>". The programmer must know how
  the concrete syntax is transformed into this abstract syntax.</p>

<p>A simpler solution is to use one of the quotation kits
  "<tt>q_MLast.cmo</tt>" or "<tt>q_ast.cmo</tt>". Both propose
  <a href="quot.html">quotations</a> which represent the abstract
  syntax (the nodes of the module "<tt>MLast</tt>") into concrete
  syntax with antiquotations to bind variables inside. The example
  above can be written:</p>

<pre>
  &lt;:expr&lt; if $e1$ then $e2$ else $e3$ >>
</pre>

<p>This representation is very interesting when one wants to
  manipulate complicated syntax trees. Here is an example taken from
  the Camlp5 sources themselves:</p>

<pre>
  &lt;:expr&lt;
    match try Some $f$ with [ Stream.Failure -> None ] with
    [ Some $p$ -> $e$
    | _ -> raise (Stream.Error $e2$) ]
  >>
</pre>

<p>This example was in a position of a pattern. In abstract syntax, it
  should have been written:</p>

<pre>
  MLast.ExMat _
    (MLast.ExTry _ (MLast.ExApp _ (MLast.ExUid _ (Ploc.VaVal "Some")) f)
       (Ploc.VaVal
          [(MLast.PaAcc _ (MLast.PaUid _ (Ploc.VaVal "Stream"))
             (MLast.PaUid _ (Ploc.VaVal "Failure")),
            Ploc.VaVal None, MLast.ExUid _ (Ploc.VaVal "None"))]))
    (Ploc.VaVal
       [(MLast.PaApp _ (MLast.PaUid _ (Ploc.VaVal "Some")) p,
         Ploc.VaVal None, e);
        (MLast.PaAny _, Ploc.VaVal None,
         MLast.ExApp _ (MLast.ExLid _ (Ploc.VaVal "raise"))
           (MLast.ExApp _
              (MLast.ExAcc _ (MLast.ExUid _ (Ploc.VaVal "Stream"))
                 (MLast.ExUid _ (Ploc.VaVal "Error")))
              e2))])
</pre>

<p>Which is less readable and much more complicated to build and
  update.</p>

<p>Instead of thinking of "a syntax tree", the programmer can think of
  "a piece of program".</p>

<h2>Location</h2>

<p>In all syntax tree nodes, the first parameter is the source
  location of the node.</p>

<h3>In expressions</h3>

<p>When a quotation is in the context of an expression, the location
  parameter is "<tt>loc</tt>" in the node and in all its possible
  sub-nodes. Example: if we consider the quotation:</p>

<pre>
  &lt;:sig_item&lt; value foo : int -> bool >>
</pre>

<p>This quotation, in a context of an expression, is equivalent
  to:</p>

<pre>
  MLast.SgVal loc (Ploc.VaVal "foo")
    (MLast.TyArr loc (MLast.TyLid loc (Ploc.VaVal "int"))
       (MLast.TyLid loc (Ploc.VaVal "bool")));
</pre>

<p>The name "<tt>loc</tt>" is predefined. However, it is possible to
  change it, using the argument "<tt>-loc</tt>" of the Camlp5 shell
  commands.</p>

<p>Consequently, if there is no variable "<tt>loc</tt>" defined in the
  context of the quotation, or if it is not of the good type, a
  semantic error occur in the OCaml compiler ("Unbound value
  loc").</p>

<p>Note that in the <a href="grammars.html">extensible grammars</a>,
  the variable "<tt>loc</tt>" is bound, in all semantic actions, to
  the location of the rule.</p>

<p>If the created node has no location, the programmer can define a
  variable named "<tt>loc</tt>" equal to "<tt>Ploc.dummy</tt>".</p>

<h3>In patterns</h3>

<p>When a quotation is in the context of a pattern, the location
  parameter of all nodes and possible sub-nodes is set to the wildcard
  ("<tt>_</tt>"). The same example above:</p>

<pre>
  &lt;:sig_item&lt; value foo : int -> bool >>
</pre>

<p>is equivalent, in a pattern, to:</p>

<pre>
  MLast.SgVal _ (Ploc.VaVal "foo")
    (MLast.TyArr _ (MLast.TyLid _ (Ploc.VaVal "int"))
       (MLast.TyLid _ (Ploc.VaVal "bool")))
</pre>

<p>However, it is possible to generate a binding of the variable
  "<tt>loc</tt>" on the top node by writing a "colon" before the
  "less" in the quotation. The same example:</p>

<pre>
  &lt;:sig_item:&lt; value foo : int -> bool >>
</pre>

<p>is equivalent to:</p>

<pre>
  MLast.SgVal loc (Ploc.VaVal "foo")
    (MLast.TyArr _ (MLast.TyLid _ (Ploc.VaVal "int"))
       (MLast.TyLid _ (Ploc.VaVal "bool")))
</pre>

<h2>Antiquotations</h2>

<p>The expressions or patterns between dollar ($) characters are
  called <em>antiquotations</em>. In opposition to quotations which
  has its own syntax rules, the antiquotation is an area in the syntax
  of the enclosing context (expression or pattern). See the chapter
  about <a href="quot.html">quotations</a>.</p>

<p>If a quotation is in the context of an expression, the
  antiquotation must be an expression. It could be any expression,
  including function calls. Examples:</p>

<pre>
  value f e el = &lt;:expr&lt; [$e$ :: $loop False el$] >>;
  value patt_list p pl = &lt;:patt&lt; ( $list:[p::pl]$) >>;
</pre>

<p>If a quotation is in the context of an pattern, the antiquotation
  is a pattern. Any pattern is possible, including the wildcard
  character ("<tt>_</tt>"). Examples:</p>

<pre>
   fun [ &lt;:expr&lt; $lid:op$ $_$ $_$ >> -> op ]
   match p with [ &lt;:patt&lt; $_$ | $_$ >> -> Some p ]
</pre>

<h2>Two kinds of antiquotations</h2>

<h3>Preliminary remark</h3>

<p>In strict mode, we remark that most constructors defined of the
  module "<tt>MLast</tt>" are of type "<tt>Ploc.vala</tt>". This type
  is defined like this:</p>

<pre>
  type vala 'a =
    [ VaAnt of string
    | VaVal of 'a ]
  ;
</pre>

<p>The type argument is the real type of the node. For example, a
  value of type "<tt>bool</tt>" in transitional mode is frequently
  represented by a value of type "<tt>Ploc.vala bool</tt>".</p>

<p>The first case of the type "<tt>vala</tt>" corresponds to an
  antiquotation in the concrete syntax. The second case to a normal
  syntax situation, without antiquotation.</p>

<p>Example: in the "let" statement, the fact that it is "rec" or not
  is represented by a boolean. This boolean is, in the syntax tree,
  encapsulated with the type "<tt>Ploc.vala</tt>". The syntax tree of
  the two following lines:</p>

<pre>
  let x = y in z
  let rec x = y in z
</pre>

<p>start with, respectively:</p>

<pre>
  MLast.ExLet loc (Ploc.VaVal False)
    ... (* and so on *)
</pre>

<p>and:</p>

<pre>
  MLast.ExLet loc (Ploc.VaVal True)
    ... (* and so on *)
</pre>

<p>The case "<tt>Ploc.VaAnt s</tt>" is internally used by the parsers
  and by the quotation kit "<tt>q_ast.cmo</tt>" to record
  antiquotation strings representing the expression or the patterns
  having this value. For example, in this "let" statement:</p>

<pre>
  MLast.ExLet loc (Ploc.VaAnt s)
    ... (* and so on *)
</pre>

<p>The contents of this "<tt>s</tt>" is internally handled. For
  information, it contains the antiquotation string (kind included)
  together with representation of the location of the antiquotation
  in the quotation. See the next section.</p>

<h3>Antiquoting</h3>

<p>To antiquotate the fact that the "let" is with or without rec (a flag
  of type boolean), there are two ways.</p>

<h4>direct antiquoting</h4>

<p>The first way, hidding the type "<tt>Ploc.val</tt>", can be
  written with the antiquotation kind "flag":</p>

<pre>
  &lt;:expr&lt; let $flag:rf$ x = y in z >>
</pre>

<p>This corresponds to the syntax tree:</p>

<pre>
  MLast.ExLet loc (Ploc.VaVal rf)
     ... (* and so on *)
</pre>

<p>And, therefore, the type of the variable "<tt>rf</tt>" is simply
  "<tt>bool</tt>".</p>

<h4>general antiquoting</h4>

<p>The second way, introducing variables of type "<tt>Ploc.vala</tt>"
  can be written a kind prefixed by "<tt>_</tt>", namely here
  "<tt>_flag</tt>":</p>

<pre>
  &lt;:expr&lt; let $_flag:rf$ x = y in z >>
</pre>

<p>In that case, it corresponds to the syntax tree:</p>

<pre>
  MLast.ExLet loc rf
     ... (* and so on *)
</pre>

<p>And, therefore, the type of the variable "<tt>rf</tt>" is now
  "<tt>Ploc.vala bool</tt>".</p>

<h3>Remarks</h3>

<p>The first form of antiquotation ensures the compatibility with
  previous versions of Camlp5. The syntax tree is <em>not</em> the
  same, but the bound variables keep the same type.</p>

<p>All antiquotations kinds have these two forms: one with some name
  (e.g. "flag") and one with the same name prefixed by "a"
  (e.g. "aflag").</p>

<h2>Nodes and Quotations</h2>

<p>This section describes all nodes defined in the module "MLast" of
  Camlp5 and how to write them with quotations. Notice that, inside
  quotations, one is not restricted to these elementary cases, but
  any complex value can be used, resulting on possibly complex combined
  nodes.</p>

<p>The quotation forms are described here
    in <a href="revsynt.html">revised syntax</a> (like the rest of
    this document). In reality, it depends on which quotation kit is
    loaded:</p>

<ul>
  <li>If "<tt>q_MLast.cmo</tt>" is used, the revised syntax is
    mandatory: the quotations must be in that syntax without any
    extension.</li>
  <li>If "<tt>q_ast.cmo</tt>" is used, the quotation
    syntax <em>must</em> be in the current user syntax with
    all extensions added to compile the file.</li>
</ul>

<p>Last remark: in the following tables, the variables names give
  information of their types. The details can be found in the
  distributed source file "<tt>mLast.mli</tt>".</p>

  <p>Node used in the quotation expanders to tells at conversion to
    OCaml compiler syntax tree time, that all locations of the
    sub-tree is correcty located in the quotation. By default, in
    quotations, the locations of all generated nodes are the location
    of the whole quotation. This node allows to make an exception to
    this rule, since we know that the antiquotation belongs to the
    universe of the enclosing program. See the chapter

    section about antiquotations.</p>

<h4>type_decl</h4>

<p>What is after 'type' or 'and' in a type declaration.</p>

<p>The type "<tt>type_decl</tt>" is a record type corresponding to
  a type declaration. Its definition is:</p>

<pre>
  type type_decl =
    { tdNam : (loc * Ploc.vaval string);
      tdPrm : Ploc.vala (list type_var);
      tdPrv : Ploc.vala bool;
      tdDef : ctyp;
      tdCon : Ploc.vala (list (ctyp * ctyp)) }
  ;
</pre>

<p>The field "<tt>tdNam</tt>" is the type identifier (together with its
  location in the source).</p>

<p>The field "<tt>tdPrm</tt>" is the list of its possible parameters.</p>

<p>The field "<tt>tdPrv</tt>" tells if the type is private or not.</p>

<p>The field "<tt>tdDef</tt>" is the definition of the type.</p>

<p>The field "<tt>tdCon</tt>" is the possible list of type constraints.</p>

<h2>Nodes without quotations</h2>

<p>Some types defined in the AST tree module "<tt>MLast</tt>" don't
  have an associated quotation. They are:</p>

<ul>
  <li><tt>type_var</tt></li>
  <li><tt>class_infos</tt></li>
</ul>

<h3>type_var</h3>

<p>The type "<tt>type_var</tt>" is defined as:</p>

<pre>
  type type_var = (Ploc.vala string * (bool * bool));
</pre>

<p>The first boolean is "<tt>True</tt>" if the type variable is
  prefixed by "<tt>+</tt>" ("plus" sign). The second boolean is
  "<tt>True</tt>" if the type variable is prefixed by "<tt>-</tt>"
  ("minus" sign).</p>

<h3>class_infos</h3>

<p>The type "<tt>class_infos</tt>" is a record type parametrized with
  a type variable. It is common to:</p>

<ul>
  <li>the "class declaration" ("<tt>class ...</tt>" as structure item),
    the type variable being "<tt>class_expr</tt>",</li>
  <li>the "class description" ("<tt>class ...</tt>" as signature item),
    the type variable being "<tt>class_type</tt>",</li>
  <li>the "class type declaration" ("<tt>class type ...</tt>"), the
    type variable being "<tt>class_type</tt>".</li>
</ul>

<p>It is defined as:</p>

<pre>
  type class_infos 'a =
    { ciLoc : loc;
      ciVir : Ploc.vala bool;
      ciPrm : (loc * Ploc.vala (list type_var));
      ciNam : Ploc.vala string;
      ciExp : 'a }
  ;
</pre>

<p>The field "<tt>ciLoc</tt>" is the location of the whole definition.</p>

<p>The field "<tt>ciVir</tt>" tells whether the type is virtual or not.</p>

<p>The field "<tt>ciPrm</tt>" is the list of its possible parameters.</p>

<p>The field "<tt>ciNam</tt>" is the class identifier.</p>

<p>The field "<tt>ciExp</tt>" is the class definition, depending of its
  kind.</p>
