+<h4 id="_module_name">2.1.1. module name</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed users to set the fully qualified name of the module in its declaration, such as</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[module qualified::module::name(...)]</pre>

+<h4 id="_multiple_inheritance">2.1.2. multiple inheritance</h4>
+<div class="paragraph">
+<p>The acceleo 3 module declaration allowed users to declare multiple "extends" modules:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[module qualified::module::name(...) extends another::module, and::a:second::module]</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 modules can only define a single extended module.</p>
+</div>
+<div class="paragraph">
+<p><strong>Only the first extended module was taken into account</strong> in Acceleo 3 so the migration can just strip all but the first extended modules' name.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_module_imports">2.1.3. module imports</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed imports of modules through unqualified names. This is forbidden in Acceleo 4 and the fully qualified names of the imports are required.</p>
+</div>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_templates">2.2. Templates</h3>
+<div class="paragraph">
+<p><strong>Important notes:</strong> The Migration tool needs to somehow mark every template which had duplicated signatures (same name, same argument list, different pre-condition) to be manually checked after migration.</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Acceleo 4 does not allow duplicated signatures and has no pre-condition, so duplicated templates might have to be combined into a single one with their pre-condition as an <code>If-Else</code> block inside.</p>
+</li>
+<li>
+<p>Initialization blocks could be different on duplicated templates, depending on the pre-condition. The migrated <code>Let</code> block thus needs to be different per branch of the above <code>If-Else</code>.</p>
+</li>
+</ul>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 templates will automatically override their super-module templates if the signature matches. This was not the case in Acceleo 3 and matching templates thus need to be marked for manual varification.</p>
+</div>
+<div class="sect3">
+<h4 id="_overriding">2.2.1. Overriding</h4>
+<div class="paragraph">
+<p>Acceleo 3 templates allowed users to override an arbitrary template through the "overrides" keyword:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[template public aTemplateName(...) overrides anotherTemplateName]</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 only allows a template of name "xyz" to override a template from the extended module with the same "xyz" name.</p>
+</div>
+<div class="paragraph">
+<p>Furthermore, Acceleo 4 templates will automatically override their super-module’s public or protected templates if they have the same signature.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_pre_conditions">2.2.2. Pre-conditions</h4>
+<div class="paragraph">
+<p>Acceleo 4 does not allow pre-conditions on templates.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_post_treatment">2.2.3. Post-treatment</h4>
+<div class="paragraph">
+<p>Acceleo 3 used an implicit String-typed variable so the post expression could be a simple call without a variable:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[template public aTemplateName(...) post (trim())]</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 doesn’t allow implicit variables. The result of the template call will be stored in the <code>self</code> variable and the migration must thus transform this expression into:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[template public aTemplateName(...) post (self.trim())]</pre>
+</div>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_init_block">2.2.4. Init block</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed variable initialization blocks on the template:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[template public aTemplateName(...) {var1 = 'string'; var2 = param1.feature;}]</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 removes the initialization blocks altogether, so the variable declarations must be transformed into a <code>let</code> block at the start of the template.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_namesakes">2.2.5. Namesakes</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed multiple templates with the same name and same argument list to co-exist within the same module, as long as their pre-condition differed.</p>
+</div>
+<div class="paragraph">
+<p>PENDING choice, remove one of the two:
+Though Acceleo 4 will allow multiple templates with the same signature to exist in a module, only the first one will ever be resolved for a call or override, all subsequent being ignored.
+Acceleo 4 does not allow multiple templates with the same signature in a given module.</p>

+<h3 id="_query">2.3. Query</h3>
+<div class="sect3">
+<h4 id="_java_services">2.3.1. Java services</h4>
+<div class="paragraph">
+<p>The best practice for Acceleo 3 was to wrap java services inside of a query. The special <code>invoke</code> service was used to this end.</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>[query public hasStereotype(element : uml::Element, stereotypeName : String) : Boolean =

+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 allows users to directly import java services.</p>
+</div>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_file_block">2.4. File Block</h3>
+<div class="paragraph">
+<p>The second argument for the file block in Acceleo 3 was a boolean (false = overwrite the file, true = append at the end of the file).</p>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 uses an enumeration, which allows the keyword "overwrite", "append" or "create" instead.</p>

+<div class="sect3">
+<h4 id="_simplified_syntax">2.5.1. Simplified Syntax</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed for loops in two formats:</p>

+<div class="listingblock">
+<div class="content">
+<pre>[for (i : E | expr)]...[/for]</pre>

+<p>Acceleo 4 only allows for the first of these two formats.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_iteration_count">2.5.2. Iteration count</h4>
+<div class="paragraph">
+<p>Acceleo 3 defined an implicit variable, <code>i</code>, that held the current iteration count.</p>

+</div>
+<div class="sect3">
+<h4 id="_before_separator_after">2.5.3. before, separator, after</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed users to specify a <code>before</code> expression that would be inserted right before the content generated by the loop body <em>if the loop had any iteration</em>. An <code>after</code> that would similarly inserted after the loop body if it generated any content, and finally a <code>separator</code> which content would be inserted in-between each iteration result.</p>
+</div>

+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 doesn’t have any similar mechanics. The migration could convert this to a <code>Let</code> holding the content of the iteration expression, then a <code>If</code> only generating before and after if the collection is not empty. Separator could be similarly handled with an <code>If</code> generating for all but the last iteration.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_pre_condition">2.5.4. Pre-condition</h4>
+<div class="paragraph">
+<p>Acceleo 3 allowed users to specify a pre-condition that would be evaluated every iteration and that would prevent all generation for that iteration if <code>false</code>.</p>

+<div class="content">
+<pre>[for (number : Integer | Sequence{1, 2, 3}) ? (isEven(number))]

+</div>
+</div>
+<div class="paragraph">
+<p>Acceleo 4 removes the initialization blocks altogether, so the variable declarations must be transformed into a <code>let</code> block before the <code>For</code> block.</p>

+<div class="paragraph">
+<p><strong>Note</strong> the initialization block was evaluated before the for itself, and not for every loop.</p>

+</div>
+</div>
+<div class="sect2">
+<h3 id="_let_statement">2.6. Let Statement</h3>
+<div class="paragraph">
+<p>Acceleo 3 only allowed a single variable per <code>Let</code>, forcing users to have multiple nested <code>Let</code> blocks to define more. The migration could aggregate multiple nested blocks into one with multiple variables if the nested blocks don’t use one of the outer `Let’s variable.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_invocation">2.7. Invocation</h3>
+<div class="paragraph">
+<p>Acceleo 3 made use of implicit variables allowing module writers to avoid always specifying the target of an expression or call:</p>

+<p>The MTL specification enforces that "A query is required to produce the same result each time it is invoked with the same arguments.". The result of a query call was thus cached in Acceleo 3, and never reevaluated. (This behavior could be disabled through a preference for Acceleo 3.)</p>

+Acceleo 4 Language
+
+:source-highlighter: highlightjs
+:listing-caption: Listing
+:toc:
+:toclevels: 3
+:sectnums:
+:icons: image
+
+== Preface
+
+=== Intended Audience
+
+This guide was written to describe the elements composing the Acceleo 4 templating language. This will not delve into the Acceleo Query Language (AQL) description.
+
+== Module
+
+An Acceleo module is defined in its own file and is the main container for generation <<Template,templates>> (that will generate text) and <<Query,queries>> (which purpose is to extract information from the input models).
+
+The name of the module will be qualified according to its location in the source folder of the project.
+
+An Acceleo file must start with the module declaration in the following format:
+
+----
+[**
+<module documentation>
+@author <author name>
+@version <version number>
+@since <first version in which this module appeared>
+/]
+[module <module name>('http://metamodel/URI/1', 'http://metamodel/URI/1', <additional_URIs>) extends <other module qualified name>]
+----
+
+Module documentation::
+The documentation of a module is optional, and can contain both the description of the module and optional metadata such as the author and version number.
+Module name::
+The module name can only contain alphanumeric (and underscore `_`) characters and cannot start with a number.
+Metamodel URIs::
+The metamodel(s) from which this module will take types. The list has to be exhaustive: if multiple connected metamodels are used, then all must be listed in the module declaration.
+Extends::
+The qualified name of another module. Acceleo allows you to override _protected_ and _public_ visibility templates from the extended module. Extending multiple modules is not allowed.
+*Note* that the extended module's name has to be qualified, even when overriding modules located in the same package.
+
+See also the <<syntax#_module,Module syntax documentation>>.
+
+=== Imports
+
+An Acceleo module can import any number of other modules. All _public_ visibility templates and queries from the imported module(s) can be called by the importer.
+
+Importing modules can be done right after the module declaration line and requires the following format:
+
+----
+[import <other module qualified name>/]
+----
+
+*Note* that modules can only be referenced through their qualified name, even if they are located in the same package.
+
+See also the <<syntax#_import,Import>> as well as the <<syntax#_module_reference,Module Reference>> syntax documentation.
+
+=== Module Elements
+
+Following the imports declaration, any number of module element can now be written as the body of our Module. Please refer to <<Template>> and <<Query>> sections below for more information.
+
+== Template
+
+A Template is a set of Acceleo statements used to generate text. It is delimited by `[template ...][/template]` tags.
+
+The template signature must include the visbility and the name, and can optionally define a post-treatment expression.
+
+----
+[**
+<template documentation>
+@param class <documentation of the parameter>
+/]
+[template public generate(class : ecore::EClass) post (self.trim())]
+[/template]
+----
+
+visibility::
+One of
++
+* public : Public templates will be visible from all modules importing or extending the module declaring them. They can be overridden by extending modules.
+* protected : Protected templates will only be visible from extending modules and can be overridden.
+* private : Private templates are only visible by the defining module and cannot be overridden.
+name::
+The name of the template. Only alphanumeric (and underscore `_`) characters are allowed, and the name cannot start with a number.
+arguments::
+Arguments follow the <<_variable,format for variables>>.
+post::
+The post-treatment expression will be called on the result of the template (stored in variable `self`) and needs to be applicable to a String.
+
+*The result of a template is always a String.*
+
+See also the <<syntax#_template,Template syntax documentation>>.
+
+=== Main template
+
+Acceleo defines a special metadata tag on templates to specify the main entry point(s) of a generation, the template(s) that will be called first during the workflow. This metadata tag, `@main`, needs to be in the comments preceding the template, or within the template documentation
+
+Such templates do not necessarily contain a <<_file_block,File>> block themselves.
+
+Example:
+
+----
+[**
+<template documentation>
+@param class <param documentation>
+@main
+/]
+[template public generate(class : ecore::EClass)]
+[file (class.name + '.txt', overwrite)]
+Class [class.name/] structural features:
+[for (feature | class.eStructuralFeatures)]
+[feature.name/]
+[/for]
+[/file]
+[/template]
+----
+
+== Query
+
+A query is a re-useable AQL expression that can return any type of Object. They are commonly used to extract information from the input models. A query is enclosed in a `[query ...]` tag.
+
+The query signature must include the visibility and its name.
+
+----
+[**
+<query documentation>
+@param class <documentation of the parameter>
+/]
+[query public getPublicProperties(class : uml::Class) : Set(uml::Property) =
+ class.attribute->select(property : uml::Property | property.visibility = uml::VisbilityKind::public)
+/]
+----
+
+visibility::
+One of
++
+* public : Public templates will be visible from all modules importing or extending the module declaring them. They can be overridden by extending modules.
+* protected : Protected templates will only be visible from extending modules and can be overridden.
+* private : Private templates are only visible by the defining module and cannot be overridden.
+name::
+The name of the query. Only alphanumeric (and underscore `_`) characters are allowed, and the name cannot start with a number.
+arguments::
+Arguments follow the <<_variable,format for variables>>.
+return type::
+The return type describes the kind of object this query is expected to return. If the expression does not return an object of the accurate type, the evaluation will fail at runtime.
+
+See also the <<syntax#_query,Query syntax documentation>>.
+
+== File Block
+
+File blocks are used to tell the Acceleo engine it must generate the body of the `[file ...]` block in an actual file.
+
+----
+[file (<uri>, <open mode>, <charset>)][/file]
+----
+
+uri::
+An AQL expression denoting the output file name. Must evaluate to a String.
+open mode::
+The open mode for the file. This can be one of:
++
+* append : Append to the end of the file if it already exists, create it otherwise.
+* overwrite : Overwrite the whole file if it already exists, create it otherwise.
+* create : Do not change the file if it already exists, create it otherwise.
+charset::
+This can be used to tell Acceleo which charset to use for the generated file. This is optional and will default to UTF-8
+
+Example:
+
+----
+[template public generate(class : ecore::EClass)]
+[file (class.name + '.java', append, 'UTF-8')]
+[/file]
+[/template]
+----
+
+*Note* that the file will only be generated if the engine actually evaluates the file block. For example, if the template containing that block is never called, or if the file block is included in an `If` block which condition evalutes to `false`, then no file will be created.
+
+See also the <<syntax#_file_statement,File Statement syntax documentation>>.
+
+== For loops
+
+For loops in Acceleo need to be expressed using the following syntax:
+
+----
+[for (<variable> | <iteration expression>) separator(<separator expression>)]...[/for]
+----
+
+variable::
+The variable follows the <<_variable,format for variables>>. The variable type must match the result of the iteration expression. If the expression returns a collection of Strings, then the variable will be of type String. Because of this, typing the variable is optional.
+iteration expression::
+An AQL expression returning a collection of elements on which to iterate. If the expression doesn't return a collection but a single element, it will be used to iterate only once.
+separator::
+The separator expression will be evaluated to insert content in-between the content generated for each iteration of the for body. It will not be generated if the for loop doesn't generate text or only generates one iteration worth of content.
+
+Example:
+
+----
+[template public generate(class : ecore::EClass)]
+[for (feature | class.eStructuralFeatures)]
+[/for]
+[/template]
+----
+
+See also the <<syntax#_for_statement,For Statement syntax documentation>>.
+
+== If conditions
+
+The `If` statement in Acceleo uses the following syntax:
+
+----
+[if (condition)]
+[elseif (condition)]
+[else]
+[/if]
+----
+
+`elseif` and `else` are both optional. If one of the `condition` expressions does not evaluate to a boolean an error will be logged and nothing will be generated for that `if` block.
+
+See also the <<syntax#_if_statement,If Statement syntax documentation>>.
+
+== Let block
+
+Acceleo `Let` blocks use the following syntax:
+
+----
+[let <variable1> = <init expression>, <variable2> = <init expression>]
+[/let]
+----
+
+`Let` blocks allow template writers to define temporary variables that will be visible within the scope of the block.
+
+The variables follow the <<_variable,format for variables>>. All of their typing is optional since they must match the return type of their initialization expression.
+
+*Note* that all variables are immutable. Nested `Let` blocks can override the value of a variable within their own scope, but the variable will go back to its former value once outside of the nested `Let`. This will produce a warning during validation.
+
+See also the <<syntax#_let_statemnet,Let Statement syntax documentation>>.
+
+== Protected Area
+
+A protected area defines a set of statements that should only be generated if the file doesn't exist on disk or it does not contain an area with the specified protected area's identifier.
+
+Protected areas allow module writers to create a "safe" part of the generated file that can be modified directly in the generated file, without fear of these manual modifications to be lost during subsequent generations.
+
+----
+[comment @main/]
+[template public generate(class : ecore::EClass)]
+[file (class.name + '.java', overwrite, 'UTF-8')/]
+// [protected (class.name + ' imports')]
+imports java.util.List;
+// [/protected]
+
+public class [class.name.toUpperFirst()/] {
+
+}
+[/file]
+[/template]
+----
+
+The expression within the protected block's signature serves as the protected area's identifier and *must be unique* in the generated file's scope.
+
+*There must be nothing present on the line after the protected area's signature.* Otherwise, everything following said signature will be considered to be part of the area's identifier by the engine and the code will not be properly protected.
+
+Please also note that the protected area's first and last line are marked as comments in the generated code (by generating `//` at the start of their respective line, since this is Java code). This is to avoid generating invalid Java code as the markers will be present in the generated file's contents.
+
+== Variable
+
+Acceleo 4 variables use the AQL syntax and inference logic for their typing.
+
+----
+<name> : <type>
+----
+
+name::
+Name of the variable. Only alphanumeric (and underscore`_`) characters are allowed, and the name cannot start with a number.
+type::
+Type of the variable. Four different kind of types are accepted
++
+* primitive : Integer, Double, String, Boolean
+* collection : Sequence, OrderedSet. Collection types have to be further specified with their content types, such as Sequence(String) for a list of String elements.
+* eclassifier : in the form <epackage_name>::<classifier_name> such as ecore::EClass.
+* union type : in the form {<epackage_name>::<classifier_name> | <epackage_name>::<classifier_name> | ...}. This kind of typing describes a variable that can be either one of the _n_ specified classifiers. e.g. {ecore::EAttribute | ecore::EReference }.

+= Acceleo
+Acceleo 3 to Acceleo 4 migration guide
+
+:doctype: book
+:source-highlighter: rouge
+:listing-caption: Listing
+:toc:
+:toclevels: 3
+:sectnums:
+:icons: image
+
+== Preface
+
+=== Intended Audience
+
+This guide was written to describe the behavior changes between the two versions of Acceleo, for the purpose of migrating from one to the next.
+
+== Language Changes
+
+=== Modules
+
+==== module name
+
+Acceleo 3 allowed users to set the fully qualified name of the module in its declaration, such as
+
+----
+[module qualified::module::name(...)]
+----
+
+Acceleo 4 forbids anything other than the actual module name and this should thus become.
+
+----
+[module name(...)]
+----
+
+Both versions require the module name to be equal to the name of the containing file minus the extension.
+
+==== multiple inheritance
+
+The acceleo 3 module declaration allowed users to declare multiple "extends" modules:
+
+----
+[module qualified::module::name(...) extends another::module, and::a:second::module]
+----
+
+Acceleo 4 modules can only define a single extended module.
+
+*Only the first extended module was taken into account* in Acceleo 3 so the migration can just strip all but the first extended modules' name.
+
+==== module imports
+
+Acceleo 3 allowed imports of modules through unqualified names. This is forbidden in Acceleo 4 and the fully qualified names of the imports are required.
+
+=== Templates
+
+*Important notes:* The Migration tool needs to somehow mark every template which had duplicated signatures (same name, same argument list, different pre-condition) to be manually checked after migration.
+
+* Acceleo 4 does not allow duplicated signatures and has no pre-condition, so duplicated templates might have to be combined into a single one with their pre-condition as an `If-Else` block inside.
+* Initialization blocks could be different on duplicated templates, depending on the pre-condition. The migrated `Let` block thus needs to be different per branch of the above `If-Else`.
+
+Acceleo 4 templates will automatically override their super-module templates if the signature matches. This was not the case in Acceleo 3 and matching templates thus need to be marked for manual verification.
+
+==== Overriding
+
+Acceleo 3 templates allowed users to override an arbitrary template through the "overrides" keyword:
+
+----
+[template public aTemplateName(...) overrides anotherTemplateName]
+----
+
+Acceleo 4 only allows a template of name "xyz" to override a template from the extended module with the same "xyz" name.
+
+Furthermore, Acceleo 4 templates will automatically override their super-module's public or protected templates if they have the same signature.
+
+==== Pre-conditions
+
+Acceleo 4 does not allow pre-conditions on templates.
+
+==== Post-treatment
+
+Acceleo 3 used an implicit String-typed variable so the post expression could be a simple call without a variable:
+
+----
+[template public aTemplateName(...) post (trim())]
+----
+
+Acceleo 4 doesn't allow implicit variables. The result of the template call will be stored in the `self` variable and the migration must thus transform this expression into:
+
+----
+[template public aTemplateName(...) post (self.trim())]
+----
+
+==== Init block
+
+Acceleo 3 allowed variable initialization blocks on the template:
+
+----
+[template public aTemplateName(...) {var1 = 'string'; var2 = param1.feature;}]
+----
+
+Acceleo 4 removes the initialization blocks altogether, so the variable declarations must be transformed into a `let` block at the start of the template.
+
+==== Namesakes
+
+Acceleo 3 allowed multiple templates with the same name and same argument list to co-exist within the same module, as long as their pre-condition differed.
+
+PENDING choice, remove one of the two:
+Though Acceleo 4 will allow multiple templates with the same signature to exist in a module, only the last one will ever be resolved for a call or override, all subsequent being ignored.
+Acceleo 4 does not allow multiple templates with the same signature in a given module.
+
+=== Query
+
+==== Java services
+
+The best practice for Acceleo 3 was to wrap java services inside of a query. The special `invoke` service was used to this end.
+
+----
+[query public hasStereotype(element : uml::Element, stereotypeName : String) : Boolean =
+ invoke('org.eclipse.acceleo.module.sample.services.UMLServices', 'hasStereotype(org.eclipse.uml2.uml.Element, java.lang.String)', Sequence{element, stereotypeName})
+/]
+----
+
+Acceleo 4 allows users to directly import java services.
+
+=== File Block
+
+The second argument for the file block in Acceleo 3 was a boolean (false = overwrite the file, true = append at the end of the file).
+
+Acceleo 4 uses an enumeration, which allows the keyword "overwrite", "append" or "create" instead.
+
+=== For Block
+
+==== Simplified Syntax
+
+Acceleo 3 allowed for loops in two formats:
+
+----
+[for (i : E | expr)]...[/for]
+----
+
+----
+[for (expr)]...[/for]
+----
+
+In the second case, the loop variable was `self`.
+
+Acceleo 4 only allows for the first of these two formats. Note that typing the iteration variable is optional in Acceleo 4.
+
+==== Iteration count
+
+Acceleo 3 defined an implicit variable, `i`, that held the current iteration count.
+
+----
+[for (feature : ecore::EStructuralFeature | class.eStructuralFeatures)]
+iteration number [i/]
+[/for]
+----
+
+Acceleo 4 does not define any similar variable.
+
+==== before, separator, after
+
+Acceleo 3 allowed users to specify a `before` expression that would be inserted right before the content generated by the loop body _if the loop had any iteration_. An `after` that would similarly inserted after the loop body if it generated any content, and finally a `separator` which content would be inserted in-between each iteration result.
+
+----
+[for (number : Integer | Sequence{1, 2, 3}) before ('int[] array = new int[') separator (', ') after ('];')][number/][/for]
+----
+
+Acceleo 4 only supports `separator`. The migration could convert `before` and `after` into a `Let` holding the content of the iteration expression, then a `If` only generating before and after if the collection is not empty.
+
+==== Pre-condition
+
+Acceleo 3 allowed users to specify a pre-condition that would be evaluated every iteration and that would prevent all generation for that iteration if `false`.
+
+----
+[for (number : Integer | Sequence{1, 2, 3}) ? (isEven(number))]
+[number/]
+[/for]
+----
+
+Acceleo 4 does not have pre-conditions. This could be converted to an `If` at the start of the for body.
+
+==== Init block
+
+Acceleo 3 allowed variable initialization blocks on the for:
+
+----
+[for (feature : ecore::EStructuralFeature | class.eStructuralFeatures) {var : String = 'string'; className : String = class.name;}]
+[number/]
+[/for]
+----
+
+Acceleo 4 removes the initialization blocks altogether, so the variable declarations must be transformed into a `let` block before the `For` block.
+
+*Note* the initialization block was evaluated before the for itself, and not for every loop.
+
+=== Let Statement
+
+Acceleo 3 only allowed a single variable per `Let`, forcing users to have multiple nested `Let` blocks to define more. The migration could aggregate multiple nested blocks into one with multiple variables if the nested blocks don't use one of the outer `Let`'s variable.
+
+=== Invocation
+
+Acceleo 3 made use of implicit variables allowing module writers to avoid always specifying the target of an expression or call:
+
+----
+[template public generate(class : ecore::EClass)]
+[name/] is equivalent to [class.name/] or [self.name/]
+[eAllContents()/] is equivalent to [class.eAllContents()/] or [self.eAllContents()/]
+[/template]
+----
+
+The implicit variable is always `self`, but the value of `self` may not be intuitive in all cases.
+
+The migration will have to take specific care of properly replacing the implicit variable with the correct variable for Acceleo 4.
+
+==== Template
+
+Acceleo 3 : `self` is the first argument of the template.
+
+Acceleo 4 : PENDING
+
+==== Query
+
+Acceleo 3 : `self` is the first argument of the query.
+
+Acceleo 4 : PENDING
+
+==== For
+
+Acceleo 3 : `self` has the same value as the iteration variable.
+
+Acceleo 4 : PENDING
+
+==== If
+
+Acceleo 3 : The value of `self` is not changed within the `if` scope and remains the value of `self` outside of the `if`.
+
+Acceleo 4 : PENDING
+
+==== let
+
+Acceleo 3 : The value of `self` is not changed within the `let` scope and remains the value of `self` outside of the `let`.
+
+Acceleo 4 : PENDING
+
+==== Expression
+
+Acceleo 3/OCL : The value of `self` is defined by the current Acceleo scope and will not be altered by OCL.
+
+Acceleo 4/AQL : PENDING
+
+=== Module Element Call
+
+==== Template invocation
+
+Acceleo 3 allowed special template calls such as the following:
+
+----
+[template public aTemplate()]
+ [anotherTemplate() before ('inserted before generated body') separator ('in-between') after ('inserted after generated body')/]
+[/template]
+
+[template protected anotherTemplate()]
+ generated body
+[/template]
+----
+
+Both `before` and `after` expression are handled by Acceleo 3 and will respectively generate their content before and after the callee's generated text. This is true even if the callee does not generate any text.
+
+`separator` is not implemented by the engine so the migration can strip it entirely.
+
+==== Query invocation
+
+Similar to template invocations, query invocations support `before`, `separator` and `after` expressions. None of which is implemented in the Acceleo 3 generation engine so they can all be stripped entirely.
+
+=== Variable
+
+Acceleo 3 supported unqualified type names for the variables.
+
+----
+[let var : EPackage = anotherVar.eContainer()]
+ output text for EPackage named [var.name/]
+[/let]
+----
+
+Acceleo 4 only accepts qualified types for the classifiers and the above should become:
+
+----
+[let var : ecore::EPackage = anotherVar.eContainer()]
+ output text for EPackage named [var.name/]
+[/let]
+----
+
+=== Expressions
+
+Acceleo 3 was using OCL as the underlying expression language, while Acceleo 4 is using AQL. Please look at the https://www.eclipse.org/acceleo/documentation/#MigratingfromMTLqueries[AQL Documentation] for more information on migrating OCL expressions to AQL.
+
+== Behavior Changes
+
+=== Modules
+
+==== inheritance behavior
+
+In Acceleo 3, once an overriding module (child) called a public or protected template of its extended module (parent), the execution flow would never come down to the child again until we `returned` out of the callee. This is contrary to other Object-oriented languages in which a `super` template could call down an `overriden` other template from the child when necessary.
+
+If you consider the following simplified modules:
+
+----
+[module parentModule()/]
+
+[template public aTemplate()]
+ [anotherTemplate()/]
+[/template]
+
+[template protected anotherTemplate()]
+ parent behavior
+[/template]
+----
+
+----
+[module childModule() extends parentModule/]
+
+[template public main()]
+ [aTemplate()/]
+[/template]
+
+[template protected anotherTemplate()]
+ child behavior
+[/template]
+----
+
+=== Query
+
+==== Validation
+
+In Acceleo 3, the return type of a query was not validated at compile time, so it was very easy for ClassCastExceptions to occur at runtime or for invalid templates to be written with the error only detected at runtime.
+
+For example, the following will fail when we try to generate, but is valid for the compiler:
+
+----
+[template public generate(c : ecore::EClass)]
+ [file (c.name.concat('.java'), false, 'UTF-8')]
+ [for (attribute : ecore::EAttribute | getFeatures(c))]
+ attribute name : [attribute.name/] [if (attribute.iD)]is id attribute[/if]
+ [/for]
+ [/file]
+[/template]
+
+[query private getFeatures(c : ecore::EClass) : Set(ecore::EAttribute) = c.eStructuralFeatures/]
+----
+
+The template expected "getFeatures" to return a Set of Attributes, but the actual type is a set of EStructuralFeature. This will fail as soon as we try to generate for a class containing both attributes and references.
+
+Acceleo 4 validates the return type of the query's body expression.
+
+==== Cache
+
+The MTL specification enforces that "A query is required to produce the same result each time it is invoked with the same arguments.". The result of a query call was thus cached in Acceleo 3, and never reevaluated. (This behavior could be disabled through a preference for Acceleo 3.)
+
+Acceleo 4 will always reevaluate the query's body even if the same argument list is passed twice.
+
+=== Let Statement
+
+The Acceleo 3 let statement was equivalent to an "instance of" condition check to enter a block.
+
+If we consider the following let block:
+
+----
+[let var : EPackage = anotherVar.eContainer()]
+ output text for EPackage named [var.name/]
+[/let]
+----
+
+In Acceleo 3, if the result of evaluating `anotherVar.eContainer()` is of type `EPackage` (the declared type of variable `var`), then this block will output the result of evaluating its body. In any other event, this would output no text and cause no failure as the block would be simply ignored if the types do not match.
+
+In Acceleo 4, this same let block will cause validation errors if the type of `anotherVar.eContainer()` cannot be an `EPackage`.

+:toc:
+:toclevels: 3
+:sectnums:
+:icons: image
+
+== Preface
+
+This document describe the syntax of an Acceleo 4 module.
+
+The syntax is described using the https://en.wikipedia.org/wiki/Backus%E2%80%93Naur_form[Backus Naur from] (BNF).
+
+== Syntax
+
+=== Comment
+
+A comment can be used to document any part of the <<Module>>. It generates nothing if placed directly or indirectly in a <<File Statement>>. For simplification comments will not be present in the BNF representation of the grammar.
+
+[source,ebnf,subs=+macros]
+----
+<<Comment>> = '[comment ' ... '/]'
+----
+
+=== Module
+
+The module is the top level element of a .mtl file. It represent a namespace declaring <<Template>> and <<Query>>. The name of the module is qualified by the location of the file in the source folder.
+
+[source,ebnf,subs=+macros]
+----
+<<Module>> =
+
+(<<Module Documentation>>)* '[module ' <<Identifier>> '(' <<Metamodel>> ',' (<<Metamodel>>)* ')' ('extends ' <<Module Reference>>)? '/]'
+
+<<Import>>*
+
+<<Module Element>>*
+----
+
+=== Identifier
+
+An identifier is used to name elements that need to be identified, or reference element that can be identified.
+
+[source,ebnf,subs=+macros]
+----
+<<Identifier>> = [a-zA-Z_][a-zA-Z_0-9]*
+----
+
+=== Module Documentation
+
+The module documentation should contains a description of the <<Module>>.
+
+It can also contain metadata such as the author, version, and since (the version since this <<Module>> exists).
+
+[source,ebnf,subs=+macros]
+----
+<<Module Documentation>> =
+
+'[**'
+
+...
+
+('@author' ...)?
+
+('@version' ...)?
+
+('@since' ...)?
+
+...
+
+'/]'
+----
+
+=== Metamodel
+
+This is the declaration of metamodels used by the module. Metamodels are referenced using their EPackage nsURI between simple quote.
+
+[source,ebnf,subs=+macros]
+----
+<<Metamodel>> = '\'' ... '\''
+----
+
+=== Import
+
+This allows a module to import other <<Module>> or service classes.
+
+[source,ebnf,subs=+macros]
+----
+<<Import>> = '[import ' <<Module Reference>> '/]'
+----
+
+=== Module Reference
+
+The module reference is a qualified reference to a <<Module>>
+
+[source,ebnf,subs=+macros]
+----
+<<Module Reference>> = <<Module Qualified Name>>
+----
+
+=== Module Qualified Name
+
+A module's name is qualified according to its location in the source folder of a project.
+
+[source,ebnf,subs=+macros]
+----
+<<Module Qualified Name>> = <<Identifier>> ('::' <<Identifier>>)*
+----
+
+=== Module Element
+
+A module element is either a <<Template>> or a <<Query>>.
+
+[source,ebnf,subs=+macros]
+----
+<<Module Element>> = <<Template>> | <<Query>>
+----
+
+=== Template
+
+A template returns a String produced using its contained <<Statement>>, it can be called as a service. It can be preceded by a <<Module Element documentation>>.
+
+[source,ebnf,subs=+macros]
+----
+<<Template>> =
+
+'[template ' <<Visibility>> <<Identifier>> '(' <<Parameter>>(',' <<Parameter>>)* ')' ('?' <<AQL Expression>>)? ('post (' <<AQL Expression>> ')')? ']'
+
+(<<Statement>>)*
+
+'[/template]'
+----
+
+=== Visibility
+
+The visibility defines the scope in which a <<Module Element>> can be called as a service.
+
+[source,ebnf,subs=+macros]
+----
+<<Visibility>> = 'private' | 'protected' | 'public'
+----
+
+=== Parameter
+
+A parameter is used to pass a value from the caller to a callee. This value can be later referenced using its identifier.
+
+[source,ebnf,subs=+macros]
+----
+<<Parameter>> = <<Identifier>> ':' <<AQL Type Literal>>
+----
+
+=== Statement
+
+A statement is a directive used to produce an output or control the execution flow.
+
+[source,ebnf,subs=+macros]
+----
+<<Statement>> =
+
+<<File Statement>> | <<For Statement>> | <<If Statement>> | <<Let Statement>> | <<Protected Area>> | <<Expression Statement>> | <<Text Statement>>
+----
+
+==== File Statement
+
+This statement is used to start the generation of a new file. Strings returned by a statement contained directly or indirectly in the execution flow, will be generated into that file.
+
+The file statement itself returns an empty String.
+
+[source,ebnf,subs=+macros]
+----
+<<File Statement>> =
+
+'[file ' '(' <<AQL Expression>> ',' <<Open Mode Kind>> (',' <<AQL Expression>>)? ')' ']'
+
+(<<Statement>>)*
+
+'[/file]'
+----
+
+==== For Statement
+
+This statement loops over a list of values and return the concatenation of all returned String.
+
+[source,ebnf,subs=+macros]
+----
+<<For Statement>> =
+
+'[for ' '(' <<Identifier>> (':' <<AQL Type Literal>>)? '|' <<AQL Expression>> ')' ['separator(' <<AQL Expression>> ')'] ']'
+
+(<<Statement>>)*
+
+'[/for]'
+----
+
+==== If Statement
+
+This statement create a branch in the execution flow and return the String of one of its branch according to the <<AQL Expression>> evaluated to true. If a condition doesn't evaluate to a boolean an empty String is generated and an error is logged.
+
+[source,ebnf,subs=+macros]
+----
+<<If Statement>> =
+
+'[if ' '(' <<AQL Expression>> ')' ']'
+
+(<<Statement>>)*
+
+('[elseif ' '(' <<AQL Expression>> ')' ']'
+
+(<<Statement>>)*)*
+
+('[else]'
+
+(<<Statement>>)*)?
+
+'[/if]'
+----
+
+==== Let Statement
+
+This statement allows to compute one or more <<AQL Expression>> and reference their value using an identifier. It can be used to improve readability of the template or increase performance when using the same <<AQL Expression>> many times in a block of <<Statement>>.
+
+[source,ebnf,subs=+macros]
+----
+<<Let Statement>> =
+
+'[let ' <<Identifier>> (':' <<AQL Type Literal>>)? '=' <<AQL Expression>> (',' <<Identifier>> (':' <<AQL Type Literal>>)? '=' <<AQL Expression>>)* ']'
+
+(<<Statement>>)*)?
+
+'[/let]'
+----
+
+==== Protected Area
+
+This statement declares an identified area in the generated file. If the generated file exists and a protected area with the same identifier exists in its contents, then the existing content of this area is directly returned. If it doesn't exist, then the concatenation of the body's statements results is returned.
+
+[source,ebnf,subs=+macros]
+----
+<<Protected Area>> =
+
+'[protected ' '(' <<AQL Expression>> ')' ']'
+
+(<<Statement>>)*)?
+
+'[/protected]'
+----
+
+==== Expression Statement
+
+This statement returns the String representation of the evaluation of its <<AQL Expression>>.
+
+[source,ebnf,subs=+macros]
+----
+<<Expression Statement>> = '[' <<AQL Expression>> '/]'
+----
+
+==== Text Statement
+
+This is any other text outside of '[' and ']'.
+
+=== AQL Expression
+
+This is an Acceleo Query Language expression. It is used to navigate through models and call services. In the context of Acceleo, <<Template>> and <<Query>> can be called as services.
+
+TODO link AQL documentation
+
+=== AQL Type Literal
+
+This is a type literal as defined in the Acceleo Query Language.
+
+TODO link AQL documentation
+
+=== Query
+
+A query references an <<AQL Expression>> with parameters and can be called as a service. It can be preceded by a <<Module Element documentation>>.
