Les compilateurs permettent d'analyser et + manipuler des données textuelles. Leurs + applications sont très nombreuses. Hoa\Compiler propose de + manipuler plusieurs compilateurs selon les besoins.

+ +

Table des matières

+ + + +

Introduction

+ +
Ce + qui se conçoit bien s'énonce clairement, et les mots pour le dire viennent + aisément.
+

Un langage est une façon d'exprimer ou de + formuler une solution à un + problème. Et des problèmes, il en existe beaucoup. Nous + lisons et écrivons dans plusieurs langages au quotidien, et certains de ces + langages sont compris par des machines. + Cette opération est possible grâce aux compilateurs.

+

La + théorie + des langages étudie entre autres l'analyse automatique de + ces langages à travers des outils comme des automates ou des + grammaires. Il est nécessaire d'avoir un cours détaillé pour + bien comprendre tous ces concepts. Toutefois, nous allons essayer de + vulgariser un minimum pour permettre une utilisation correcte de + Hoa\Compiler.

+ +

Langage et grammaire

+ +

Un langage est un ensemble de mots. + Chaque mot est une séquence de symboles + appartenant à un alphabet. Un symbole représente la plus + petite unité lexicale d'un langage, il est atomique et nous + l'appellons lexème (ou token en anglais). + Les séquences de lexèmes représentant les mots sont construites avec des + règles. À partir d'un mot et d'une règle racine, nous allons + essayer de dériver ses sous-règles. Si une dérivation existe, + alors le mot est considéré comme valide, sinon il est + considéré comme invalide. Nous parlons aussi de + reconnaissance de mots. Par exemple, si nous considérons les + règles suivantes :

+ 
    exp ::= exp + exp
+          | nombre
+ nombre ::= chiffre nombre
+          | chiffre
+chiffre ::= 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9
+

Le mot que nous voulons reconnaître est 7 + 35. La règle + racine est exp. Si nous la dérivons (de gauche à droite + et de haut en bas, ou left-to-right et + top-to-bottom en anglais), nous pouvons avoir + exp + exp ou nombre (la + disjonction, i.e. le « ou », est représentée par le + symbole « | ») :

+ 
exp + exp | nombre
+→ exp + exp
+→ ( exp + exp | nombre ) + exp
+→ nombre + exp
+→ ( chiffre nombre | chiffre ) + exp
+

Nous continuons à dériver jusqu'à éliminer toutes les + règles et n'avoir que des lexèmes :

+ 
…
+→ ( chiffre nombre | chiffre ) + exp
+→ chiffre + exp
+→ ( 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 ) + exp
+→ 7 + exp
+→ 7 + ( exp + exp | nombre )
+→ 7 + nombre
+→ 7 + ( chiffre nombre | chiffre )
+→ 7 + chiffre nombre
+→ 7 + ( 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 ) nombre
+→ 7 + 3 nombre
+→ 7 + 3 ( chiffre nombre | chiffre )
+→ 7 + 3 chiffre
+→ 7 + 3 ( 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 )
+→ 7 + 3 5
+

Une dériviation existe bel et bien pour reconnaître le mot 7 + + 35, c'est donc un mot valide pour ces règles.

+

Un ensemble de règles est appelé une grammaire. Et donc, + une grammaire représente un langage !

+

Toutefois, il existe plusieurs catégories de grammaires. C'est en 1956 qu'a + été formulée la + hiérarchie + de Chomsky, classant les grammaires en quatre + niveaux :

+
    +
  1. grammaires générales, ou unrestricted + grammars, reconnaissant les langages dits de Turing, aucune + restriction n'est imposée aux règles ;
    2. +
  2. grammaires contextuelles, ou + context-sensitive grammars, reconnaissant les langages + contextuels ;
    3. +
  3. grammaires algébriques, ou context-free + grammars, reconnaissant les langages algébriques, basés sur les + automates à pile ;
    4. +
  4. grammaires régulières, ou regular + grammars, reconnaissant les langages réguliers.
    5. +
+

Chaque niveau reconnait le niveau suivant. Hoa\Compiler ne + traite que les langages définis par les grammaires de niveau 3 et 4. Pour + donner rapidement une idée, les grammaires régulières peuvent s'apparenter aux + expressions + régulières (comme les PCRE), bien connues + des développeurs. Mais les grammaires régulières ne permettent pas par exemple + de reconnaître des couples de symboles (comme des + parenthèses, des accolades ou des guillemets), alors que les grammaires + algébriques le permettent (grâce à la notion de piles de lexèmes).

+ +

Reconnaissance de mots

+ +
+ +

En général, le processus de compilation débute par deux + analyses : lexicale et + syntaxique. Une analyse lexicale consiste à + découper un mot en une séquence de lexèmes. + Cette séquence sera ensuite utilisée par l'analyseur syntaxique afin de + vérifier que le mot appartient au langage.

+

Selon la grammaire, la reconnaissance ne se fera pas de la même manière, + mais le principe reste identique : prendre les lexèmes les uns après les + autres dans la séquence et vérifier qu'ils permettent + d'avancer dans la dérivation des règles de + notre grammaire.

+

Les analyses syntaxiques sont aussi classées en + catégories : LL, LR, LALR etc. Hoa\Compiler ne + propose que des analyseurs syntaxiques LL, pour Left-to-right + Leftmost derivation, i.e. de la plus haute règle vers la plus + profonde, et les règles sont dérivées de la gauche vers la droite. Là encore, + il existe des sous-catégories, dont deux que traite + Hoa\Compiler : LL(1) et LL(*). D'une manière générale, on parle + d'analyseurs syntaxiques LL(k) : si un lexème ne permet pas de + dériver une règle comme il faut, alors l'analyseur peut + revenir jusqu'à k étapes en arrière ; nous parlons + aussi de backtrack. Autrement dit, les règles peuvent être + ambiguës : à chaque fois que nous dérivons une règle de la + grammaire, nous avons plusieurs choix possibles et l'analyseur peut se + tromper, c'est pourquoi il doit parfois revenir en arrière. La variable + k permet de définir le niveau d'ambiguïté. Si une + grammaire peut être analysée par un analyseur syntaxique LL(1), elle est dite + non-ambiguë : à chaque lexème utilisé pour dériver nos + règles, il n'y a qu'un seul choix possible. Et si nous avons un analyseur + syntaxique LL(*), cela signifie que la variable k est + indéfinie. L'exemple suivant illustre une grammaire + non-ambiguë :

+ 
rule ::= a b c | d e f
+

Et cet exemple illustre une grammaire ambiguë :

+ 
rule1 ::= a rule2
+rule2 ::= b rule3 | b rule4
+rule3 ::= c d
+rule4 ::= e f
+

Voyons quand nous essayons de trouver une dérivation pour le mot + abef à partir de la règle racine rule1 :

+ 
rule1
+→ a rule2                      a  bef ✔
+  → a (b rule3 | b rule4)      a  bef
+    → a b rule3               ab  ef  ✔
+      → a b c d              abe  f   ✖
+    ← a b rule3               ab  ef  ✖
+  ← a (b rule3 | b rule4)      a  bef
+    → a b rule4               ab  ef  ✔
+      → a b e f             abef      ✔
+

La règle rule2 est ambiguë, ce qui peut entraîner une mauvaise + dérivation et donc un retour en arrière, un + backtracking.

+ +

Compilateur de + compilateurs LL(k)

+ +

Écrire des compilateurs est une tâche laborieuse. Ce n'est + pas forcément toujours difficile mais souvent répétitif et long. C'est + pourquoi il existe des compilateurs de compilateurs, ou + autrement dit, des générateurs de compilateurs. La plupart du temps, ces + compilateurs de compilateurs utilisent un langage + intermédiaire pour écrire une grammaire. La bibliothèque + Hoa\Compiler propose la classe Hoa\Compiler\Llk\Llk + qui permet l'écriture de compilateurs de compilateurs à travers un langage + dédié.

+ +

Langage PP

+ +

Le langage PP, pour PHP Parser, permet d'exprimer des + grammaires algébriques. Il s'écrit dans des fichiers portant + l'extension .pp (voir le fichier + hoa://Library/Compiler/.Mime).

+

Une grammaire est constituée de lexèmes et de + règles. La déclaration d'un lexème se fait de la manière + suivante : %token namespace_in:name value -> + namespace_out, où name représente le + nom du lexème, value représente sa + valeur, au format PCRE + (attention à ne pas reconnaître de valeur vide, auquel cas une exception sera + levée), et namespace_in et + namespace_out représentent les noms des espaces + de noms et sont optionels (vaut default par défaut). Par + exemple number qui représente un nombre composé de chiffres de + 0 à 9 :

+ 
%token number \d+
+

Les espaces de noms représentent des sous-ensembles + disjoints de lexèmes, utilisés pour faciliter les analyses. + Une déclaration %skip est similaire à %token + excepté qu'elle représente un lexème à sauter, c'est à dire + à ne pas considérer. Un exemple courant de lexèmes %skip est les + espaces :

+ 
%skip space \s
+

Pour expliquer les règles, nous allons utiliser comme exemple la grammaire + Json.pp, grammaire légèrement simplifiée du + langage JSON (voir la + RFC4627). La grammaire + complète se situe dans le fichier + hoa://Library/Json/Grammar.pp. Ainsi :

+ 
%skip   space          \s
+// Scalars.
+%token  true           true
+%token  false          false
+%token  null           null
+// Strings.
+%token  quote_         "        -> string
+%token  string:string  [^"]+
+%token  string:_quote  "        -> default
+// Objects.
+%token  brace_         {
+%token _brace          }
+// Arrays.
+%token  bracket_       \[
+%token _bracket        \]
+// Rest.
+%token  colon          :
+%token  comma          ,
+%token  number         \d+
+
+value:
+    &lt;true> | &lt;false> | &lt;null> | string() | object() | array() | number()
+
+string:
+    ::quote_:: &lt;string> ::_quote::
+
+number:
+    &lt;number>
+
+#object:
+    ::brace_:: pair() ( ::comma:: pair() )* ::_brace::
+
+#pair:
+    string() ::colon:: value()
+
+#array:
+    ::bracket_:: value() ( ::comma:: value() )* ::_bracket::
+

Nous remarquons que nous avons deux espaces de noms pour les lexèmes : + default et string (cela permet de ne pas + confondre les lexèmes quote_ et + string:_quote qui ont la même représentation). Nous remarquons + ensuite la règle value qui est une disjonction + de plusieurs lexèmes et règles. Les constructions du langage + PP sont les suivantes :

+
    +
  • rule() pour appeler une + règle ;
    • +
  • &lt;token> et ::token:: + pour déclarer un lexème (les espaces de noms n'apparaissent + pas ici) ;
    • +
  • | pour une disjonction (un choix) ;
    • +
  • (…) pour grouper ;
    • +
  • e? pour dire que e est + optionel ;
    • +
  • e+ pour dire que e peut + apparaître 1 ou plusieurs fois ;
    • +
  • e* pour dire que e peut + apparaître 0 ou plusieurs fois ;
    • +
  • e{x,y} pour dire que e + peut apparaître entre x et y + fois ;
    • +
  • #node pour créer un nœud + node dans l'arbre ;
    • +
  • token[i] pour unifier + des lexèmes entre eux.
    • +
+

Peu de constructions mais amplement suffisantes.

+

Enfin, la grammaire du langage PP est écrite… dans le langage PP ! Vous + pourrez la trouver dans le fichier + hoa://Library/Compiler/Llk/Llk.pp.

+ +

Processus de compilation

+ +
+ +

Le processus de compilation qu'utilise Hoa\Compiler\Llk\Llk + est classique. Il commence par analyser lexicalement la + donnée textuelle, le mot, i.e. à transformer notre donnée en une + séquence de lexèmes. L'ordre de déclaration des lexèmes est + primordial car l'analyseur lexical va les prendre les uns après les autres. + Ensuite, c'est l'analyseur syntaxique qui entre en jeu afin + de reconnaître notre donnée.

+

Si l'analyse syntaxique est un succès, nous obtenons une + trace. Cette trace peut être transformée en AST, pour + Abstract Syntax Tree. Cet arbre représente notre donnée + textuelle après analyse. Il a l'avantage de pouvoir être visité (nous + détaillerons plus loin), ce qui permet par exemple d'ajouter de nouvelles + contraintes qui ne peuvent pas être exprimées dans la + grammaire, comme une vérification de type.

+

Manipulons un peu Hoa\Compiler\Llk\Llk. Cette classe est un + assistant pour lire une grammaire au format PP facilement. + Elle prend en seul argument un flux en lecture vers la grammaire et retourne + un compilateur Hoa\Compiler\Llk\Parser prêt à l'emploi. Sur ce + compilateur, nous allons appeler la méthode + Hoa\Compiler\Llk\Parser::parse pour analyser une donnée JSON. Si + la donnée est correcte, nous aurons en retour un AST, sinon une exception sera + levée. Enfin, nous allons utiliser le visiteur + Hoa\Compiler\Visitor\Dump pour afficher notre AST :

+ 
// 1. Load grammar.
+$compiler = Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp'));
+
+// 2. Parse a data.
+$ast      = $compiler->parse('{"foo": true, "bar": [null, 42]}');
+
+// 3. Dump the AST.
+$dump     = new Hoa\Compiler\Visitor\Dump();
+echo $dump->visit($ast);
+
+/**
+ * Will output:
+ *     >  #object
+ *     >  >  #pair
+ *     >  >  >  token(string:string, foo)
+ *     >  >  >  token(true, true)
+ *     >  >  #pair
+ *     >  >  >  token(string:string, bar)
+ *     >  >  >  #array
+ *     >  >  >  >  token(null, null)
+ *     >  >  >  >  token(number, 42)
+ */
+

Quand nous écrivons et testons une grammaire, nous allons répéter ces trois + tâches très régulièrement. C'est pourquoi, le script + hoa propose la commande compiler:pp. Cette commande + propose d'analyser une donnée par rapport à une grammaire et d'appliquer un + visiteur si besoin sur l'AST résultant. Notons que la lecture de la donnée + peut se faire à travers un + pipe :

+ 
$ echo '[1, [1, [2, 3], 5], 8]' | hoa compiler:pp Json.pp 0 --visitor dump
+>  #array
+>  >  token(number, 1)
+>  >  #array
+>  >  >  token(number, 1)
+>  >  >  #array
+>  >  >  >  token(number, 2)
+>  >  >  >  token(number, 3)
+>  >  >  token(number, 5)
+>  >  token(number, 8)
+

C'est un moyen pratique pour tester rapidement des données + par rapport à notre grammaire. Il ne faut pas hésiter à regarder l'aide de la + commande compiler:pp pour plus de détails !

+

Les analyses s'effectuent sur la règle racine mais nous + pouvons préciser une autre règle à l'aide du deuxième + argument de la méthode Hoa\Compiler\Llk\Parser::parse :

+ 
$compiler->parse('{"foo": true, "bar": [null, 42]}', 'object');
+

Pour utiliser la règle racine, il suffit de passer null.

+

Et enfin, pour ne pas générer l'AST mais uniquement savoir si la donnée est + valide ou pas, nous pouvons utiliser le dernier argument de notre méthode en + lui passant false :

+ 
$valid = $compiler->parse('{"foo": true, "bar": [null, 42]}', null, false);
+var_dump($valid);
+
+/**
+ * Will output:
+ *     bool(true)
+ */
+ +

Erreurs

+ +

Les erreurs de compilation sont remontées à travers des exceptions, + ainsi :

+ 
$ echo '{"foo" true}' | hoa compiler:pp Json.pp 0 --visitor dump
+Uncaught exception (Hoa\Compiler\Exception\UnexpectedToken):
+Hoa\Compiler\Llk\Parser::parse(): (0) Unexpected token "true" (true) at line 1
+and column 8:
+{"foo" true}
+       ↑
+in hoa://Library/Compiler/Llk/Parser.php at line 1
+

Plusieurs exceptions peuvent remonter selon le contexte :

+
    +
  • durant l'analyse lexicale, + Hoa\Compiler\Exception\UnrecognizedToken quand un lexème n'est + pas reconnu, i.e. quand la donnée textuelle ne peut plus être + découpée en une séquence de lexèmes, et + Hoa\Compiler\Exception\Lexer quand d'autres erreurs plus + générales arrivent, par exemple si un lexème reconnaît une valeur + vide ;
    • +
  • durant l'analyse syntaxique, + Hoa\Compiler\Exception\UnexpectedToken quand un lexème n'est + pas attendu, i.e. qu'il ne permet plus de dériver les règles de la + grammaire.
    • +
+

L'exception parente est Hoa\Compiler\Exception\Exception.

+ +

Nœuds

+ +

Le processus de compilation aboutit très souvent à la + production d'un AST. Il est important de contrôler sa + forme, sa taille, les données qu'il + contient etc. C'est pourquoi il est nécessaire de comprendre + la notation #node car elle permet de créer des + nœuds dans l'AST. Une précision tout d'abord, les lexèmes + déclarés avec la syntaxe &lt;token> apparaîtront + dans l'arbre, alors que les autres lexèmes, déclarés avec la syntaxe + ::token::, n'y apparaîtront pas. En effet, dans notre + dernier exemple, les lexèmes quote_, brace_, + colon, comma etc. n'apparaissent pas. Ensuite, il + est important de noter que les déclarations de nœuds se + surchargent les unes par rapport aux autres au sein d'une + même règle. Enfin, un nom de règle peut être précédé par + #, comme pour la règle #array, qui permet de définir + un nœud par défaut, mais il peut être surchargé. Par exemple, + si nous remplaçons la règle array par :

+ 
#array:
+    ::bracket_:: value() ( ::comma:: value() #bigarray )* ::_bracket::
+

Si le tableau ne contient qu'une seule valeur, le nœud s'appelera + #array, sinon il s'appelera #bigarray ; voyons + plutôt :

+ 
$ echo '[42]' | hoa compiler:pp Json.pp 0 --visitor dump
+>  #array
+>  >  token(number, 42)
+$ echo '[4, 2]' | hoa compiler:pp Json.pp 0 --visitor dump
+>  #bigarray
+>  >  token(number, 4)
+>  >  token(number, 2)
+

Bien sûr, il peut arriver qu'un nœud soit créé ou pas selon le dérivation + empruntée dans la règle. Le mécanisme est normalement assez + intuitif.

+ +

Espace de noms

+ +

Détaillons un peu le fonctionnement de l'analyseur lexical vis à vis des + espaces de noms.

+

Les lexèmes sont placés dans des espaces de noms, + c'est à dire que seuls les lexèmes de l'espace de noms + courant seront utilisés par l'analyseur lexical. L'espace de + noms par défaut est default. Pour déclarer l'espace de noms d'un + lexème, il faut utiliser l'opérateur :. Quand un lexème est + consommé, il peut changer l'espace courant pour la suite de + l'analyse lexicale, grâce à l'opérateur ->. Ainsi, nous allons + déclarer cinq lexèmes : foo et bar dans l'espace + default, baz dans ns1 et + qux et foo dans ns2. Le fait de + déclarer deux fois foo n'est pas gênant car ils sont dans des + espaces de noms différent :

+ 
%token      foo   fo+     -> ns1
+%token      bar   ba?r+   -> ns2
+%token  ns1:baz   ba?z+   -> default
+%token  ns2:qux   qux+
+%token  ns2:foo   FOO     -> ns1
+

Écrire default:bar est strictement équivalent à + bar. Le lexème foo emmène dans ns1, + bar dans ns2, ns1:baz dans + default, ns2:qux reste dans ns2 et + ns2:foo emmène dans ns1. Observons la séquence de + lexèmes produite par l'analyseur lexical avec la donnée + fooooobzzbarrrquxFOObaz :

+ 
$pp = '%token      foo   fo+     -> ns1'     . "\n" .
+      '%token      bar   ba?r+   -> ns2'     . "\n" .
+      '%token  ns1:baz   ba?z+   -> default' . "\n" .
+      '%token  ns2:qux   qux+'               . "\n" .
+      '%token  ns2:foo   FOO     -> ns1';
+
+// 1. Parse PP.
+Hoa\Compiler\Llk\Llk::parsePP($pp, $tokens, $rawRules);
+
+// 2. Run the lexical analyzer.
+$lexer    = new Hoa\Compiler\Llk\Lexer();
+$sequence = $lexer->lexMe('fooooobzzbarrrquxFOObaz', $tokens);
+
+// 3. Pretty-print the result.
+$format   = '%' . (strlen((string) count($sequence)) + 1) . 's  ' .
+            '%-13s %-20s  %-20s  %6s' . "\n";
+$header   = sprintf($format, '#', 'namespace', 'token name', 'token value', 'offset');
+
+echo $header, str_repeat('-', strlen($header)), "\n";
+
+foreach($sequence as $i => $token)
+    printf(
+        $format,
+        $i,
+        $token['namespace'],
+        $token['token'],
+        $token['value'],
+        $token['offset']
+    );
+
+/**
+ * Will output:
+ *      #  namespace     token name            token value           offset
+ *     ---------------------------------------------------------------------
+ *      0  default       foo                   fooooo                     0
+ *      1  ns1           baz                   bzz                        6
+ *      2  default       bar                   barrr                      9
+ *      3  ns2           qux                   qux                       14
+ *      4  ns2           foo                   FOO                       17

+ *      6  default       EOF                   EOF                       23
+ */
+

Nous lisons les lexèmes, leur espace et leur valeur dans le tableau. La + donnée a pu être découpée, et nous sommes passés d'un espace + à un autre. Si cette fois nous essayons avec la donnée foqux, + nous aurons une erreur : fo correspond au lexème foo + dans l'espace default, nous changeons alors d'espace pour + ns1, et là, aucun lexème dans cet espace ne peut reconnaître au + moins q. Une erreur sera levée.

+

Jusqu'à maintenant, nous avons vu comment passer d'un espace à l'autre avec + l'opérateur ->. Aucun historique sur les espaces + traversés n'est conservé. Toutefois, dans certains cas rares, il peut arriver + qu'un espace de lexèmes soit accessible via plusieurs autres + et que nous aimerions qu'un lexème déclenche le retour vers l'espace de noms + précédent. Autrement dit, nous aimerions un historique des + espaces traversés et pouvoir y naviguer (en arrière uniquement). C'est le rôle + du mot-clé __shift__ * n, à utiliser après l'opérateur + -> et à la place du nom d'un espace. __shift__ est + équivalent à dire : revient à l'espace précédent. __shift__ est + équivalent à __shift__ * 1, et + __shift__ * n à : revient n fois à + l'espace précédent.

+

Lorsque le mot-clé __shift__ apparaît dans la grammaire, les + espaces sont gérés comme une pile, d'où le vocabulaire + shift. Il faut faire attention à bien dépiler les espaces + pour ne pas avoir une pile trop conséquente.

+

Prenons en exemple la grammaire suivante :

+ 
%token       foo1  a    -> ns1
+%token       foo2  x    -> ns2
+%token       end   e
+
+%token   ns1:bar   b
+%token   ns1:baz   c    -> ns3
+%token   ns1:tada  t    -> __shift__
+
+%token   ns2:bar   y
+%token   ns2:baz   z    -> ns3
+%token   ns2:tada  T    -> __shift__
+
+%token   ns3:qux   =   -> __shift__
+
+#test:
+    ( &lt;foo1> | &lt;foo2> ) &lt;bar> &lt;baz> &lt;qux> &lt;tada> &lt;end>
+

Cette grammaire reconnaît deux données : abc=te et + xyz=Te. Si le premier lexème foo1 est rencontré, + l'analyseur syntaxique changera d'espace pour ns1. Quand il + rencontrera le lexème ns1:baz, il passera dans ns3. + Ensuite, quand il rencontrera ns3:qux, il reviendra à l'espace + précédent, soit ns1. Et ainsi de suite. Maintenant, s'il ne + rencontre pas foo1 mais foo2, il ira dans l'espace + ns2, puis dans ns3 puis à nouveau ns2. + Les mots-clés __shift__ pour ns1:tada et + ns2:tada n'ont pas d'autres buts que de dépiler les espaces, mais + aucune ambiguïté n'existe : ces espaces ne sont accessibles que par un seul + espace, à savoir default.

+

Maintenant, enregistrons cette grammaire dans un fichier + NamespaceStack.pp et utilisons l'option + -s/--token-sequence de la commande hoa + compiler:pp :

+ 
$ echo -n 'abc=te' | hoa compiler:pp CrazyNamespace.pp 0 --token-sequence
+ #  namespace     token name            token value                     offset
+-------------------------------------------------------------------------------
+ 0  default       foo1                  a                                    0
+ 1  ns1           bar                   b                                    1

Nous voyons que l'analyse lexicale à réussi à jongler avec les espaces de + noms, comme attendu. Nous avions deux façons d'accéder à l'espace + ns3 : soit depuis ns1, soit depuis ns2. + L'analyseur a réussi à créer un historique des espaces et à y naviguer.

+ +

Unification

+ +

Une caractéristique qu'apporte le langage PP par rapport à d'autres + langages de grammaires connus est la capacité d'exprimer une + unification de lexèmes. Imaginons la grammaire + suivante :

+ 
%token  quote   '|"
+%token  string  \w+
+
+rule:
+    ::quote:: &lt;string> ::quote::
+

Les guillemets qui entourent la chaîne de caractère peuvent être de deux + sortes : simple, avec le symbole « ' », ou double, avec le + symbole « " ». Ainsi, les données "foo" et + 'foo' sont valides, mais également + "foo' et 'foo" !

+

L'unification des lexèmes permet d'ajouter une contraine + supplémentaire sur la valeur des lexèmes à l'exécution. La + syntaxe est la suivante : token[i]. La valeur + de i indique quels lexèmes vont devoir porter la même + valeur. Et enfin, l'unification est locale à une instance + d'une règle, c'est à dire qu'il n'y a pas d'unification entre les lexèmes de + plusieurs règles et que cela s'applique sur la règle appelée + uniquement. Ainsi, l'exemple devient :

+ 
rule:
+    ::quote[0]:: &lt;string> ::quote[0]::
+

Ce qui invalide les données "foo' et 'foo".

+

L'unification trouve de nombreuses applications, comme par exemple unifier + les noms des balises ouvrantes et fermantes du + langage XML.

+ +

Abstract Syntax + Tree

+ +
+ +

Un arbre syntaxique abstrait représente la donnée + textuelle sous forme structurelle. Chaque + nœud de cet arbre est représenté par la classe + Hoa\Compiler\Llk\TreeNode. Parmis les méthodes utiles, nous + trouvons :

+
    +
  • getId pour obtenir l'identifiant du nœud ;
    • +
  • getValueToken pour obtenir le nom du lexème ;
    • +
  • getValueValue pour obtenir la valeur du lexème ;
    • +
  • isToken si le nœud représente un lexème ;
    • +
  • getChild($i) pour obtenir le + $i-ème enfant d'un nœud ;
    • +
  • getChildren pour obtenir tous les nœuds ;
    • +
  • getChildrenNumber pour connaître le nombre d'enfants ;
    • +
  • getParent pour obtenir le nœud parent ;
    • +
  • getData pour obtenir une référence vers un tableau de + données ;
    • +
  • accept pour appliquer un visiteur.
    • +
+

Les visiteurs sont le moyen le plus pratique pour + parcourir un AST. En guise d'exemple, nous allons écrire le + visiteur PrettyPrinter qui va réécrire une donnée JSON avec notre + propre convention (espacements, retours à la ligne etc.). Un visiteur doit + implémenter l'interface Hoa\Visitor\Visit et n'aura qu'une seule + méthode à écrire : visit qui prend trois arguments : + l'élément et deux arguments accessoires (en copie et en référence). Voyons + plutôt :

+ 
class PrettyPrinter implements Hoa\Visitor\Visit {
+
+    public function visit ( Hoa\Visitor\Element $element,
+                            &amp;$handle = null, $eldnah = null ) {
+
+        static $i      = 0;
+        static $indent = '    ';
+
+        // One behaviour per node in the AST.
+        switch($element->getId()) {
+
+            // Object: { … }.
+            case '#object':
+                echo '{', "\n";
+                ++$i;
+
+                foreach($element->getChildren() as $e => $child) {
+
+                    if(0 &lt; $e)
+                        echo ',', "\n";
+
+                    echo str_repeat($indent, $i);
+                    $child->accept($this, $handle, $eldnah);
+                }
+
+                echo "\n", str_repeat($indent, --$i), '}';
+              break;
+
+            // Array: [ … ].
+            case '#array':
+                echo '[', "\n";
+                ++$i;
+
+                foreach($element->getChildren() as $e => $child) {
+
+                    if(0 &lt; $e)
+                        echo ',', "\n";
+
+                    echo str_repeat($indent, $i);
+                    $child->accept($this, $handle, $eldnah);
+                }
+
+                echo "\n", str_repeat($indent, --$i), ']';
+              break;
+
+            // Pair: "…": ….
+            case '#pair':
+                echo $element->getChild(0)->accept($this, $handle, $eldnah),
+                     ': ',
+                     $element->getChild(1)->accept($this, $handle, $eldnah);
+              break;
+
+            // Many tokens.
+            case 'token':
+                switch($element->getValueToken()) {
+
+                    // String: "…".
+                    case 'string':
+                        echo '"', $element->getValueValue(), '"';
+                      break;
+
+                    // Booleans.
+                    case 'true':
+                    case 'false':
+
+                    // Null.
+                    case 'null':
+
+                    // Number.
+                    case 'number':
+                        echo $element->getValueValue();
+                      break;
+                }
+              break;
+        }
+    }
+}
+

Nous allons voir tout de suite un exemple d'utilisation :

+ 
$compiler    = Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp'));
+$ast         = $compiler->parse('{"foo": true, "bar": [null, 42]}');
+$prettyPrint = new PrettyPrinter();
+echo $prettyPrint->visit($ast);
+
+/**
+ * Will output:
+ *     {
+ *         "foo": true,
+ *         "bar": [
+ *             null,
+ *             42
+ *         ]
+ *     }
+ */
+

La méthode getData est très pratique pour + stocker des données susceptibles d'être + réutilisées, par exemple d'un visiteur à l'autre. Cette + méthode retourne une référence sur un tableau ; ainsi :

+ 
$data = $element->getData();
+
+if(!isset($data['previousComputing']))
+    throw new Exception('Need a previous computing.', 0);
+
+$previous = $data['previousComputing'];
+

Il est courant d'utiliser un visiteur par contrainte : + vérifiation des symboles, vérification de types etc. Certains peuvent laisser + des données nécessaires pour le suivant. La méthode getData + n'impose aucune structuration des données, elle propose uniquement un accès à + un tableau. Ce sera à vous de faire le reste.

+

Utiliser la classe Hoa\Compiler\Llk\TreeNode est vraiment + trivial et nous l'utiliserons la plupart du temps avec un + visiteur.

+ +

Traces

+ +
+ +

Le compilateur LL(k) que propose Hoa est clairement découpé en + plusieurs couches. Chaque couche est exploitable pour + permettre une modularité maximum. Quand la grammaire est traduite en « règles + machines » et que les analyseurs lexical et syntaxique ont validé une donnée, + il en résulte une trace. Cette trace est un tableau composé + de trois classes seulement :

+
    +
  • Hoa\Compiler\Llk\Rule\Entry quand l'analyseur syntaxique + est rentré dans une règle ;
    • +
  • Hoa\Compiler\Llk\Rule\Ekzit quand l'analyseur syntaxique + est sorti d'une règle ;
    • +
  • Hoa\Compiler\Llk\Rule\Token quand l'analyseur syntaxique a + rencontré un lexème.
    • +
+

Nous pouvons l'obtenir grâce à la méthode + Hoa\Compiler\Llk\Parser::getTrace. Pour bien comprendre cette + trace, nous allons commencer par un exemple :

+ 
$compiler = Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp'));
+$ast      = $compiler->parse('{"foo": true, "bar": [null, 42]}');
+$i        = 0;
+
+foreach($compiler->getTrace() as $element)
+    if($element instanceof Hoa\Compiler\Llk\Rule\Entry)
+        echo str_repeat('>   ', ++$i), 'enter ', $element->getRule(), "\n";
+    elseif($element instanceof Hoa\Compiler\Llk\Rule\Token)
+        echo str_repeat('    ', $i + 1), 'token ', $element->getTokenName(),
+             ', consumed ', $element->getValue(), "\n";
+    else
+        echo str_repeat('&lt;   ', $i--), 'ekzit ', $element->getRule(), "\n";
+
+/**

+ *                                                 token number, consumed 42
+ *     &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   ekzit value
+ *     &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   ekzit 20
+ *     &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   ekzit 21
+ *                                     token _bracket, consumed ]
+ *     &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   ekzit array
+ *     &lt;   &lt;   &lt;   &lt;   &lt;   &lt;   ekzit value

+ *     &lt;   &lt;   &lt;   ekzit 13
+ *                 token _brace, consumed }
+ *     &lt;   &lt;   ekzit object
+ *     &lt;   ekzit value
+ */
+

Cet exemple nous révèle plusieurs choses. Tout d'abord, les informations + que nous donne la trace peuvent être utiles : si nous sommes sur une règle, + nous avons son nom (avec la méthode getRule), et + si nous sommes sur un lexème, nous avons son nom (avec la + méthode getTokenName), sa représentation (sous + la forme d'une PCRE, avec la méthode getRepresentation), sa + valeur (avec la méthode getValue), si c'est un + nœud à conserver dans l'AST (avec la méthode + isKept) et son index d'unification s'il existe + (avec la méthode getUnificationIndex). Bien sûr, tout ceci est + modifiable, ce qui peut influencer la construction de l'AST qui est le + processus (optionnel) suivant.

+

Ensuite, nous remarquons que parfois nous entrons dans une règle qui existe + dans la grammaire, comme object, pair, + value etc., et parfois nous entrons dans une règle + numérique, comme 13, 12, + 21, 20 etc. Quand la grammaire est interprétée pour + être transformée en « règles machines », chacune de ses règles est + linéarisée selon les opérateurs du langage PP :

+
    +
  • Hoa\Compiler\Llk\Rule\Choice pour une disjonction ;
    • +
  • Hoa\Compiler\Llk\Rule\Concatenation pour une + concaténation ;
    • +
  • Hoa\Compiler\Llk\Rule\Repetition pour une répétition ;
    • +
  • Hoa\Compiler\Llk\Rule\Token pour un lexème (déjà vu + précédemment).
    • +
+

Toutes les règles sous ce format sont accessibles à travers la méthode + Hoa\Compiler\Llk\Parser::getRules sous la forme d'un tableau. + Nous allons afficher toutes les règles accessibles depuis la + règle racine pour mieux comprendre :

+ 
$compiler = Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp'));
+
+// 1. Get all rules.
+$rules    = $compiler->getRules();
+
+// 2. Start with the root rule.
+$stack    = array($compiler->getRootRule() => true);
+
+while(false !== current($stack)) {
+
+    $rule = key($stack);
+    next($stack);
+    echo "\n", '"', $rule, '" is a ',
+         strtolower(substr(get_class($rules[$rule]), 22));
+
+    $subrules = $rules[$rule]->getContent();
+
+    // 3a. Token.
+    if(null === $subrules)
+        continue;
+
+    echo ' of rules: ';
+
+    // 3b. Other rules.
+    foreach((array) $rules[$rule]->getContent() as $subrule) {
+
+        if(!array_key_exists($subrule, $stack))
+            // 4. Unshift new rules to print.
+            $stack[$subrule] = true;
+
+        echo $subrule, ' ';
+    }
+}
+
+/**
+ * Will output:
+ *     "value" is a choice of rules: 1 2 3 string object array number
+ *     "1" is a token
+ *     "2" is a token
+ *     "3" is a token
+ *     "string" is a concatenation of rules: 5 6 7
+ *     "object" is a concatenation of rules: 10 pair 13 14
+ *     "array" is a concatenation of rules: 18 value 21 22
+ *     "number" is a token
+ *     "5" is a token
+ *     "6" is a token
+ *     "7" is a token
+ *     "10" is a token
+ *     "pair" is a concatenation of rules: string 16 value

+ *     "20" is a concatenation of rules: 19 value
+ *     "11" is a token
+ *     "19" is a token
+ */
+

Si nous lisons la règle object, nous savons que c'est la + concaténation des règles 10, pair, 13 + et 14. 10 est un lexème, pair est la + concaténation des règles string, 16 et + value, et ainsi de suite. La grammaire initiale est transformée + pour être sous sa forme la plus réduite possible. Ceci permet + de raisonner beaucoup plus facilement et + rapidement sur les règles. En effet, les traitements sur la + grammaire ne sont pas réservés aux AST. À l'étape précédente, avec la trace, + nous pouvons déjà effectuer des traitements.

+ +

Génération

+ +

Une grammaire peut être utile pour deux objectifs : + valider une donnée (si nous la voyons comme un automate) ou + générer des données. Jusqu'à présent, nous avons vu comment + valider une donnée à travers plusieurs processus : + préparation de notre compilateur, exécution des + analyseurs lexical et syntaxique résultant sur une + trace, transformation de la trace vers un + AST pour enfin visiter cet arbre. Mais nous + pouvons nous arrêter à la première étape, la préparation de notre compilateur, + pour exploiter les règles afin de générer une donnée qui sera valide par + rapport à notre grammaire.

+

Hoa\Compiler\Llk\Sampler propose trois algorithmes de + générations de données :

+
    +
  • génération aléatoire et uniforme ;
    • +
  • génération exhaustive bornée ;
    • +
  • génération basée sur la couverture.
    • +
+

Pourquoi proposer trois algorithmes ? Parce qu'il est illusoire de penser + qu'un seul algorithme peut suffir aux nombreux contextes + d'utilisations. Chacun répond à des besoins différents, nous l'expliquerons + plus loin.

+

Générer une donnée à partir d'une grammaire se fait en deux + étapes :

+
    +
  1. générer des valeurs pour les lexèmes afin d'avoir des données + brutes ;
    2. +
  2. générer un chemin dans les règles de la grammaire.
    3. +
+

Un chemin est équivalent à une dérivation, le vocabulaire est différent + selon notre objectif : validation ou génération.

+ +

Génération + isotropique de lexèmes

+ +

Pour générer les valeurs des lexèmes, peu importe l'algorithme utilisé, il + doit être rapide. Nous allons utiliser un parcours dit + isotrope. Nous partons d'une règle et nous avançons + uniquement à partir de choix aléatoires et uniformes + localement (uniquement pour ce choix). Par exemple si nous avons une + disjonction entre trois sous-règles, nous allons tirer aléatoirement et + uniformément entre 1 et 3. Si nous avons une concaténation, nous allons juste + concaténer chaque partie. Et enfin, une répétition n'est rien d'autre qu'une + disjonction de concaténation : en effet, e{1,3} est + strictement équivalent à e | ee | eee. + Illustrons plutôt :

+ 
([ae]+|[x-z]!){1,3}              repeat [ae]+|[x-z]! 2 times
+→ ([ae]+|[x-z]!)([ae]+|[x-z]!)  choose between [ae]+ and [x-z]!

+→ eay!
+

Cette génération est naïve mais ce n'est pas important. Ce + qui est vraiment important est la génération des chemins dans les règles, ou + autrement dit, la génération des séquences de lexèmes.

+ +

Génération aléatoire + et uniforme

+ +

Le premier algorithme est celui de la génération aléatoire + et uniforme. Cet algorithme est utile si nous voulons générer + des séquences de lexèmes de taille n fixe et avec + une uniformité non pas locale (comme avec un parcours + isotrope) mais sur l'ensemble de toutes les séquences + possibles. Succinctement, l'algorithme travaille en deux étapes : + pré-calcul (une seule fois par taille) puis + génération. Le pré-calcul est une étape + automatique et calcule le nombre de + séquences et sous-séquences possibles de taille n. Cette étape aide + au calcul de fonctions de distributions pour + guider la génération des séquences de lexèmes finales.

+

Nous allons générer 10 données aléatoires de taille 7, c'est à dire + composées de 7 lexèmes. Pour cela, nous allons utiliser la classe + Hoa\Compiler\Llk\Sampler\Uniform qui prend en premier argument + notre grammaire, en deuxième le générateur de valeurs de lexèmes (ici + Hoa\Regex\Visitor\Isototropic) et enfin la taille :

+ 
$sampler = new Hoa\Compiler\Llk\Sampler\Uniform(
+    // Grammar.
+    Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp')),
+    // Token sampler.
+    new Hoa\Regex\Visitor\Isotropic(new Hoa\Math\Sampler\Random()),
+    // Length.
+    7
+);
+
+for($i = 0; $i &lt; 10; ++$i)
+    echo $i, ' => ', $sampler->uniform(), "\n";
+
+/**
+ * Will output:
+ *     0 => [ false , null , null ]
+ *     1 => [ " l " , null ]
+ *     2 => [ [ true ] , true ]
+ *     3 => [ [ [ 4435 ] ] ]
+ *     4 => [ [ [ 9366 ] ] ]
+ *     5 => [ true , false , null ]
+ *     6 => { " |h&lt;# " : false }
+ *     7 => [ [ [ false ] ] ]
+ *     8 => [ false , true , 7 ]
+ *     9 => [ false , 5 , 79 ]
+ */
+

Nous pouvons redéfinir la taille avec la méthode + Hoa\Compiler\Llk\Sampler\Uniform::setLength. Nous aurons + peut-être remarqué que certains opérateurs de répétition n'ont pas de bornes + supérieures, comme + ou * ; dans ce cas, nous la + définissons à n.

+ +

Génération exhaustive + bornée

+ +

Le deuxième algorithme est celui de la génération exhaustive + bornée. Cet algorithme génère toutes les séquences + (c'est le côté exhaustif) de lexèmes de taille 1 jusqu'à + n (c'est le caractère borné). Un aspect très intéressant de cet + algorithme est que l'exhaustivité est une forme de preuve ! + L'algorithme fonctionne comme un itérateur et est très simple à utiliser :

+ 
$sampler = new Hoa\Compiler\Llk\Sampler\BoundedExhaustive(
+    // Grammar.
+    Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp')),
+    // Token sampler.
+    new Hoa\Regex\Visitor\Isotropic(new Hoa\Math\Sampler\Random()),
+    // Length.
+    7
+);
+
+foreach($sampler as $i => $data)
+    echo $i, ' => ', $data, "\n";
+
+/**
+ * Will output:
+ *     0 => true
+ *     1 => false
+ *     2 => null
+ *     3 => " 8u2 "
+ *     4 => { " ,M@aj{ " : true }
+ *     5 => { " x`|V " : false }
+ *     6 => { " NttB " : null }
+ *     7 => { " eJWwA " : 0 }
+ *     8 => [ true ]
+ *     9 => [ true , true ]
+ *     10 => [ true , true , true ]
+ *     11 => [ true , true , false ]
+ *     12 => [ true , true , null ]
+ *     13 => [ true , true , 32 ]
+ *     14 => [ true , false ]
+ *     15 => [ true , false , true ]
+ *     16 => [ true , false , false ]
+ *     17 => [ true , false , null ]
+ *     18 => [ true , false , 729 ]
+ *     19 => [ true , null ]
+ *     20 => [ true , null , true ]
+ *     21 => [ true , null , false ]
+ *     …
+ *     157 => [ 780 , 01559 , 32 ]
+ *     158 => 344
+ */
+

A l'instar de l'algorithme précédent, nous pouvons redéfinir la + borne maximum avec la méthode + Hoa\Compiler\Llk\Sampler\BoundedExhaustive::setLength. Et les + opérateurs de répétition sans borne supérieure utilisent n.

+ +

Génération basée + sur la couverture

+ +

Le dernier algorithme est celui de la génération basée sur la + couverture. Cet algorithme réduit l'explosion + combinatoire rencontrée avec l'algorithme précédent mais l'objectif + est tout autre : il va générer des séquences de lexèmes qui vont + « activer » toutes les branches des règles + de la grammaire. Une règle est dite couverte si et seulement si ses + sous-règles sont toutes couvertes, et un lexème est dit couvert s'il a été + utilisé dans une séquence. Pour assurer une diversité dans + les séquences produites, les points de choix entre des sous-règles non + couvertes sont résolus par tirages aléatoires. L'algorithme + fonctionne également comme un itérateur :

+ 
$sampler = new Hoa\Compiler\Llk\Sampler\Coverage(
+    // Grammar.
+    Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp')),
+    // Token sampler.
+    new Hoa\Regex\Visitor\Isotropic(new Hoa\Math\Sampler\Random())
+);
+
+foreach($sampler as $i => $data)
+    echo $i, ' => ', $data, "\n";
+
+/**
+ * Will output:
+ *     0 => true
+ *     1 => { " )o?bz " : null , " %3W) " : [ false , 130 , " 6 " ] }
+ *     2 => [ { " ny  " : true } ]
+ *     3 => { " Ne;[3 " : [ true , true ] , " th: " : true , " C[8} " : true }
+ */
+

Pour éviter l'explosion combinatoire et assurer la + termination de l'algorithme, nous utilisons + l'heuristique suivante sur les opérateurs de + répétition : * répétera 0, + 1 et 2 fois, + répétera 1 + et 2 fois, et enfin {x,y}, + répétera x, x + 1, + y - 1 et y fois. Cette heuristique + trouve ses origines dans le test aux limites.

+

Nous remarquons dans notre exemple que 4 données sont générées et suffisent + à couvrir l'ensemble de notre grammaire !

+ +

Comparaison entre + les algorithmes

+ +

Voici quelques indices pour savoir quand utiliser tel ou + tel autre algorithme.

+
+
Génération aléatoire et uniforme :
+
    +
  • rapide pour des petites données, grande diversité dans + les données et taille fixe ;
    • +
  • la phase de pré-calcul est exponentielle et donc + longue bien que, ensuite, la génération soit très rapide.
    • +
+
Génération exhaustive bornée :
+
    +
  • rapide pour des petites données et l'exhaustivité est + efficace ;
    • +
  • nombre exponentiel de données.
    • +
+
Génération basée sur la couverture :
+
    +
  • rapide pour des données de taille moyenne ou grande, + et diversité des données ;
    • +
  • ne considère pas de taille.
    • +
+
+ +

Compilateur de + compilateurs LL(1)

+ +

La documentation pour le compilateur LL(1), à travers la classe + Hoa\Compiler\Ll1 n'est pas encore écrite. L'objectif est + différent de Hoa\Compiler\Llk : il n'existe pas de langage + intermédiaire, les automates sont codés en dur avec des tableaux et ce type de + compilateurs est orienté haute performance. C'est pourquoi son comportement + est monolothique.

+ +

Conclusion

+ +

Hoa\Compiler propose deux compilateurs de + compilateurs : Hoa\Compiler\Llk et + Hoa\Compiler\Ll1, afin de valider des données. + Le langage PP permet d'écrire des grammaires + algébriques de manière simple et + naturelle. Le compilateur de compilateurs LL(k) est + découpé en processus distincts ce qui le rend très + hackable. Enfin, différents algorithmes permettent de + générer des données à partir d'une grammaire selon le + contexte d'utilisation.

A +dedicated grammar language is provided for the last one: the PP language. + +## Installation + +With [Composer](http://getcomposer.org/), to include this library into your +dependencies, you need to require +[`hoa/compiler`](https://packagist.org/packages/hoa/compiler): + +```json +{ + "require": { + "hoa/compiler": "~2.0" + } +} +``` + +Please, read the website to [get more informations about how to +install](http://hoa-project.net/Source.html). + +## Quick usage + +As a quick overview, we will look at the PP language and the LL(k) compiler +compiler. + +### The PP language + +A grammar is constituted by tokens (the units of a word) and rules (please, see +the documentation for an introduction to the language theory). The PP language +declares tokens with the following construction: + +``` +%token [namespace:]name value [-> namespace] +``` + +The default namespace is `default`. The value of a token is represented by a +[PCRE](http://pcre.org/). We can skip tokens with the `%skip` construction. + +As an example, we will take the *simplified* grammar of the [JSON +language](http://json.org/). The complete grammar is in the +`hoa://Library/Json/Grammar.pp` file. Thus: + +``` +%skip space \s +// Scalars. +%token true true +%token false false +%token null null +// Strings. +%token quote_ " -> string +%token string:string [^"]+ +%token string:_quote " -> default +// Objects. +%token brace_ { +%token _brace } +// Arrays. +%token bracket_ \[ +%token _bracket \] +// Rest. +%token colon : +%token comma , +%token number \d+ + +value: + | | | string() | object() | array() | number() + +string: + ::quote_:: ::_quote:: + +number: + + +#object: + ::brace_:: pair() ( ::comma:: pair() )* ::_brace:: + +#pair: + string() ::colon:: value() + +#array: + ::bracket_:: value() ( ::comma:: value() )* ::_bracket:: +``` + +We can see the PP constructions: + + * `rule()` to call a rule; + * `` and `::token::` to declare a token; + * `|` for a disjunction; + * `(…)` to group multiple declarations; + * `e?` to say that `e` is optional; + * `e+` to say that `e` can appear at least 1 time; + * `e*` to say that `e` can appear 0 or many times; + * `e{x,y}` to say that `e` can appear between `x` and `y` times; + * `#node` to create a node the AST (resulting tree); + * `token[i]` to unify tokens value between them. + +Unification is very useful. For example, if we have a token that expresses a +quote (simple or double), we could have: + +``` +%token quote "|' +%token handle \w+ + +string: + ::quote:: ::quote:: +``` + +So, the data `"foo"` and `'foo'` will be valid, but also `"foo'` and `'foo"`! To +avoid this, we can add a new constraint on token value by unifying them, thus: + +``` +string: + ::quote[0]:: ::quote[0]:: +``` + +All `quote[0]` for the rule instance must have the same value. Another example +is the unification of XML tags name. + +### LL(k) compiler compiler + +The `Hoa\Compiler\Llk\Llk` class will transform a grammar into a compiler. The +following code will use the previous grammar to create a compiler, and we will +parse a JSON string. If the parsing succeed, it will produce an AST (stands for +Abstract Syntax Tree) we can visit, for example to dump the AST: + +```php +// 1. Load grammar. +$compiler = Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp')); + +// 2. Parse a data. +$ast = $compiler->parse('{"foo": true, "bar": [null, 42]}'); + +// 3. Dump the AST. +$dump = new Hoa\Compiler\Visitor\Dump(); +echo $dump->visit($ast); + +/** + * Will output: + * > #object + * > > #pair + * > > > token(string, foo) + * > > > token(true, true) + * > > #pair + * > > > token(string, bar) + * > > > #array + * > > > > token(null, null) + * > > > > token(number, 42) + */ +``` + +Pretty simple. + +### Compiler in CLI + +This library proposes a script to parse and apply a visitor on a data with a +specific grammar. Very useful. Moreover, we can use pipe (because +`Hoa\File\Read` —please, see the [`Hoa\File` +library](http://central.hoa-project.net/Resource/Library/File/)— supports `0` as +`stdin`), thus: + +```sh +$ echo '[1, [1, [2, 3], 5], 8]' | hoa compiler:pp Json.pp 0 --visitor dump +> #array +> > token(number, 1) +> > #array +> > > token(number, 1) +> > > #array +> > > > token(number, 2) +> > > > token(number, 3) +> > > token(number, 5) +> > token(number, 8) +``` + +You can apply any visitor classes. + +### Errors + +Errors are well-presented: + +```sh +$ echo '{"foo" true}' | hoa compiler:pp Json.pp 0 --visitor dump +Uncaught exception (Hoa\Compiler\Exception\UnexpectedToken): +Hoa\Compiler\Llk\Parser::parse(): (0) Unexpected token "true" (true) at line 1 +and column 8: +{"foo" true} + ↑ +in hoa://Library/Compiler/Llk/Parser.php at line 1 +``` + +### Samplers + +Some algorithms are available to generate data based on a grammar. We will give +only one example with the coverage-based generation algorithm that will activate +all branches and tokens in the grammar: + +```php +$sampler = new Hoa\Compiler\Llk\Sampler\Coverage( + // Grammar. + Hoa\Compiler\Llk\Llk::load(new Hoa\File\Read('Json.pp')), + // Token sampler. + new Hoa\Regex\Visitor\Isotropic(new Hoa\Math\Sampler\Random()) +); + +foreach($sampler as $i => $data) + echo $i, ' => ', $data, "\n"; + +/** + * Will output: + * 0 => true + * 1 => { " )o?bz " : null , " %3W) " : [ false , 130 , " 6 " ] } + * 2 => [ { " ny " : true } ] + * 3 => { " Ne;[3 " : [ true , true ] , " th: " : true , " C[8} " : true } + */ +``` + +## Documentation + +Different documentations can be found on the website: +[http://hoa-project.net/](http://hoa-project.net/). + +## License + +Hoa is under the New BSD License (BSD-3-Clause).
