Les syllabes sont comptées en scandant sans - élision des <em>e</em> muets sauf quand un mot se termine par un <em>e</em> - muet et le mot suivant commence par une voyelle ou un <em>h</em> non aspiré - (ou si c'est le dernier mot du vers). Le nombre de syllabes n'est <em>pas</em> - ce que vous obtenez en lisant le poème comme vous parlez tous les jours. - Certains groupes de voyelles peuvent prendre deux syllabes soit - systématiquement (par exemple "Léon") soit par une <em>diérèse</em> facultative - ou obligatoire ("passion")&nbsp;; plint utilise une approximation permissive - des diérèses effectivement autorisées déduite à partir d'un corpus de textes - classiques.</dd> - <dt id="whatcheck_hemistiche">Hémistiche</dt> - <dd>Les alexandrins classiques sont divisés en deux <em>hémistiches</em> de - 6 syllabes. La césure ne doit pas couper un mot et le premier hémistiche ne - doit pas se finir par un son faible (ie. une fin féminine non élidée).</dd> - <dt id="whatcheck_rhyme">Rime</dt> - <dd>La contrainte poétique la plus connue est que les vers doivent rimer. Les - phonèmes communs dans une rime doivent inclure un son vocalique (par exemple - "tâte" et "bête" ne riment pas parce que leur suffixe commun est [t] qui ne - contient pas de son vocalique). Les rimes sont vérifiées par plint avec une - approximation permissive de la prononciation de la fin des vers. Plint confond - [ɛ] et [ɛː] ("mettre" et "maître") et [a] et [ɑ] ("patte" et "pâte") mais pas - [ɛ̃] et [œ̃] ("brin" et "brun") ou [ɔ] et [o] ("cotte" et "côte"). Quand toutes - les règles classiques sont suivies, certaines rimes comme la rime normande ou - la rime avec liaison supposée sont acceptées.</dd> - <dt id="whatcheck_eye">Rime pour l'œil</dt> - <dd>En poésie classique, un degré minimal de rime "pour l'œil" est exigé - (ainsi "-é" et "-er" ne riment pas), avec une certaine tolérance (pour "-é" et - "-ai" notamment).</dd> - <dt id="whatcheck_genre">Genre des rimes.</dt> - <dd>En poésie classique, les rimes doivent être <em>féminines</em> ou - <em>masculines</em>. Une rime est féminine si elle se termine par un "e", "es" - ou "ent" silencieux, et est masculine dans le cas contraire. Les rimes doivent - faire rimer alternativement deux terminaisons féminines et deux terminaisons - masculines. plint vérifie cela, avec une approximation permissive pour - déterminer si une terminaison est féminine ou non.</dd> - <dt id="whatcheck_ambiguous">Motifs ambigus</dt> - <dd>Certains motifs comme "-ies" et "-ées", ou "-ie" ou "-ée" suivis - d'une consonne ou d'un 'h' aspiré, sont interdits en poésie classique. - La raison est que ces motifs sont ambigus car ils pouvaient être prononcés ou - élidés suivant les règles classiques de prosodie à l'époque, ce qui empêchait - de compter correctement les syllabes. Selon la prosodie moderne, ils sont - toujours élidés, mais ils sont toujours interdits suivant les règles - classiques : plint les signale.</dd> - <dt id="whatcheck_hiatus">Hiatus</dt> - <dd>Le hiatus (juxtaposition de sons vocaliques sans 'e' muet intercalaire) - est interdit en poésie classique et signalé. Plus précisément, il y a hiatus - lorsqu'un mot se termine par une voyelle (sauf 'e' muet) et que le mot suivant - commence par une voyelle ou par un <em>h</em> non-aspiré. Les consonnes - muettes en fin de mot évitent l'hiatus, sauf dans le cas particulier du mot - "et" (dont on considère qu'il se termine par un son vocalique).</dd> - <dt id="whatcheck_repeated">Mots répétés</dt> - <dd>On ne doit pas faire rimer un mot avec lui-même (mais on peut faire rimer - un mot avec des homographes de nature grammaticale différente), ainsi, plint - signale une erreur si le nombre d'occurrences d'un mot connu dans un motif de - rimes est plus grand par son nombre de natures grammaticales possibles.</dd> - <dt id="whatcheck_illegal">Caractères interdits</dt> - <dd>Les caractères que plint ne reconnaît pas (notamment les chiffres arabes) - sont signalés comme des erreurs, d'une part parce qu'ils sont sans doute - irréguliers en poésie classique, d'autre part parce que cela signifie sans - doute que plint va mal interpréter le vers.</dd> - <dt id="whatcheck_length">Longueur</dt> - <dd>Pour certains types de poèmes (par exemple les sonnets), le nombre de vers - est fixé, et une erreur est levée si le modèle n'est pas complet ou s'il a été - répété.</dd> -</dl> - -<h2>Qu'est-ce qui n'est pas vérifié par plint&nbsp;?</h2> - -<p>Le comptage des syllabes est effectué par une approximation permissive qui -peut autoriser certaines diérèses ou synérèses non autorisées. Aucune -vérification n'est faite pour s'assurer que la césure à l'hémistiche se fait à -une position grammaticale raisonnable. Les rimes sont calculées par une -approximation permissive, et il en va de même pour les genres. Il est interdit -de faire rimer des mots dérivés l'un de l'autre (par exemple "justice" et -"injustice") mais plint, faute de données, ne peut vérifier pas cette -contrainte. Plint ne vérifie pas que les mots sont correctement orthographiés ou -s'ils existent effectivement en français, ou si le poème a un sens de façon -générale&nbsp;: par exemple, <q>Tatata tatati tatati tatata</q> est reconnu -comme un alexandrin classique parfaitement valide.</p> - -<h2 id="log">Vie privée&nbsp;: Est-ce que des logs sont conservés&nbsp;?</h2> - -<p>Oui, des logs peuvent être conservés, afin de pouvoir identifier, quand le -programme plante, pourquoi le poème d'entrée l'a fait planter. Je conserve donc -des informations sur les requêtes entrantes (poème, adresse IP).

Le premier est obligatoire, les deux derniers -sont facultatifs. -</p> -<p> -La métrique indique le nombre de syllabes du vers, et la position des -hémistiches éventuelles. Il s'agit de totaux de syllabes, séparés par '/' pour -indiquer les hémistiches. Par exemple, "6/6" est un alexandrin classique, "12" -est un alexandrin non nécessairement pourvu de césure à l'hémistiche. -</p> -<p> -L'identifiant de rime sert à regrouper les vers qui doivent rimer ensemble. Les -vers ayant le même identifiant doivent rimer. Pour préciser le type de rime -attendue, il est possible de terminer l'identifiant par ':' suivie d'une liste -de valeurs séparées par '|'. La première valeur est soit "no" pour désactiver -les contraintes classiques sur la rime (et n'exiger que la rime phonétique), -soit n'importe quoi d'autre pour activer les règles classiques (ce qui est fait -par défaut). La seconde valeur est un nombre minimal de phonèmes communs -nécessaires pour qu'une rime soit acceptée (1 par défaut). -</p> -<p> -L'identifiant de genre de rime sert à regrouper les vers qui doivent avoir une -rime de même genre. Les conventions supplémentaires sont que deux identifiants -de casse inversée (tels que "ex" et "EX") ont des genres opposés -obligatoirement, et que "m" et "f" sont obligatoirement masculin et féminin -respectivement. -</p> -<p> -Si des identifiants ne sont pas spécifiés, alors la contrainte correspondante -n'est pas spécifiée. -</p> -<p> -Une fois le format épuisé, il est lu à nouveau à partir du début, jusqu'à la fin -du poème. Les identifiants de rime et de genre sont réinitialisés (ie. peuvent -prendre n'importe quelle valeur), sauf ceux qui commencent par '!'.

If none of the -predefined templates suit you, you can <a href="#template">write your - own</a>.</p> - -<h2 id="whatcheck">What does plint check?</h2> -<p>Here are some simplified explanations. To know all the details, go read the -source code.</p> -<dl> - <dt id="whatcheck_syllable">Syllable count</dt> - <dd>The number of syllables in each verse is usually fixed (12 in - alexandrines, for instance). Syllables are counted in a reading with no - elision of mute <em>e</em>'s except at the end of a word <em>and</em> when - the following word starts with a vowel or non-aspirated <em>h</em> (or if it - is the last word). The syllable count is <em>not</em> what you get with a - colloquial everyday reading. Some vowels clusters can count for two - syllables either naturally ("Léon") or through <em>diérèse</em> ("passion"); - plint uses a tolerant approximation of allowed <em>diérèses</em> trained on a - corpus of classical texts.</dd> - <dt id="whatcheck_hemistiche">Hemistiche</dt> - <dd>For classical alexandrines, the 12 syllables are separated in two groups - of 6 with an intermediate cesura (the <em>hémistiche</em>). The cesura must - not split a word and must not end in a weak sound (essentially, a non-elided - feminine ending).</dd> - <dt id="whatcheck_rhyme">Rhyme.</dt> - <dd>The fact that verses must rhyme is the most well-known poetic constraint. - The rhyming phonemes must include a vowel (eg. "tâte" and "bête" do not rhyme - because their common phoneme suffix is [t] which does not include a vowel - sound). plint enforces rhymes trough a liberal approximation of the - pronunciation of verse endings. Plint merges [ɛ] et [ɛː] ("mettre" and - "maître") and [a] and [ɑ] ("patte" and "pâte") but distinguishes [ɛ̃] and [œ̃] - ("brin" and "brun") and [ɔ] and [o] ("cotte" and "côte"). When all classical - rules are enforced, some rhymes such as <em>rime normande</em> and rhymes for - a <em>liaison supposée</em> are accepted though they do not rhyme - phonetically.</dd> - <dt id="whatcheck_eye">Eye rhyme.</dt> - <dd>Classical rules require a minimal degree of <em>rime pour l'œil</em> (end - letter similarity); thus "-é" and "-er" do not rhyme, although common - tolerances exist, such as allowing "-é" and "-ai".</dd> - <dt id="whatcheck_genre">Rhyme genre.</dt> - <dd>In classical verse, rhymes must be made between feminine verse endings, or - masculine verse endings. A verse ending is feminine if it ends with a silent - "e", "es" or "ent", and masculine otherwise. plint enforces this, with a - liberal approximation to try to guess if an ending is indeed silent. Besides, - feminine and masculine rhymes must alternate.</dd> - <dt id="whatcheck_ambiguous">Ambiguous patterns</dt> - <dd>Some patterns such as "-ées" or "-ies", or "-ée" and "-ie" followed by an - aspirated 'h' or a consonant, are forbidden by classical rules. They are - called "ambiguous" because, according to classical prosody rules at the time, - they could be either pronounced or elided, so it was unclear how to count - syllables. In modern French, they are always elided, but classical poetry - still prohibits them. They are - reported by plint.</dd> - <dt id="whatcheck_hiatus">Hiatus</dt> - <dd>Juxtaposition of vowel sounds in two adjacent words with no mute 'e' in - the middle is forbidden and reported. Specifically, it is forbidden to end a - word with a vowel (except mute 'e') and have the next word start with a vowel - or a non-aspirated <em>h</em>. Mute consonants at the end of the word avoid - hiatus, except in the specific case of the word "et" (which is considered to - end by a vowel sound).</dd> - <dt id="whatcheck_repeated">Repeated words</dt> - <dd>A word may not rhyme with itself, but may rhyme with a homograph of a - different grammatical nature, so plint will report as error any multiple - occurrences of a known word in a rhyme pattern if the number of occurrences is - more than the number of grammatical natures for the word.</dd> - <dt id="whatcheck_illegal">Illegal characters</dt> - <dd>Characters that are not understood by plint, such as arabic numerals, are - reported as errors: on the one hand, they are probably best avoided in - classical poetry; on the second hand plint will probably misinterpret the - verse if it does not understand some of the characters.</dd> - <dt id="whatcheck_length">Poem length</dt> - <dd>For some poetic forms such as the <em>sonnet</em>, the number of verses is - fixed, so an error is raised if the pattern was not completed to the end or - was repeated.</dd> -</dl> - -<h2>What isn't checked by plint?</h2> - -<p>Syllable count is performed by a liberal estimate which may allow some -invalid <em>diérèses</em> and <em>synérèses</em> to make the count match. It is -not checked if <em>hémistiches</em> occur at a sensible grammatical position. -Rhyme is computed by a liberal heuristic, as well as rhyme genre. Rhymes between -words derived from one another, such as <em>justice</em> and <em>injustice</em>, -are usually not allowed, -but this is not checked by plint for lack of adequate data. More importantly, -plint will not check if the words you use exist in French, or are correctly -spelt, and if your poem makes any sense, does not contain spelling mistakes or -has any poetic value; it only enforces formal constraints. For instance, -<q>Tatata tatati tatati tatata</q> is recognized as a perfectly correct -classical alexandrine.</p> - -<h2 id="log">Privacy: Do you keep logs?</h2> - -<p>Yes, I do, because whenever the program chokes on a poem I need to figure out -what happened, and I need the input poem for that, so I keep a trace of incoming -requests (poem, IP address, etc.). Hence, if you want to run plint on confidential or -personal poems, do not submit them to the online version; instead, retrieve the -<a href="https://a3nm.net/git/plint">source code</a> and run plint locally.</p> - -<h2 id="template">How can I define my own templates?</h2> - -<p>Each template line will be checked against a non-blank poem line. When the -template is finished, it starts over from the beginning, and the rhyme and rhyme -genre identifiers (see below) are reinitialized unless they start with a '!'. -Each line contains one to three space-separated fields. The fields will be -interpreted in the following order:</p> -<ol> -<li>The first field is the <strong>metric indication</strong>. It is a list of -syllable counts separated by '/'s to indicate <em>hémistiches</em>. For -instance, "6/6" is a classical alexandrine, "12" is an alexandrine without -<em>hémistiche</em>. For technical reasons, the total number of syllables in a -verse is limited to 16.</li> -<li>The second field is the <strong>rhyme identifier</strong>. Verses with the -same rhyme identifier must rhyme. You can suffix the pattern with ":" followed -by a rhyme constraint. The rhyme constraint is up to two '|'-separated -values. The first value is either "no" to disable classical constraints and only -enforce phonetic rhyming, or anything else (default) to enable classical -constrains. The second value is a number of required common phonemes (default -1).</li> -<li>The third field is the <strong>rhyme genre</strong>. Verses with the same -rhyme genre identifier must have the same rhyme genre. Identifiers with opposite -case (like "ex" and "EX") must represent opposite genres, "m" must represent -masculine, "f" must represent feminine.</li> -</ol> -<p>Global options can be stated in lines starting with "! ", they are of the -form option:value and separated by spaces, with the following possibilities:</p> -<dl> - <dt>merge</dt> - <dd>The value should be a list of X-SAMPA phonemes (with plint's custom - mapping of multi-character to single-character phonemes) to merge (for - instance "oO"). Rhymes will be computed up to these merges.</dd> - <dt>normande_ok</dt> - <dd>The value should be true or false to allow or refuse rimes normandes. - Default is true.</dd> - <dt>hiatus_ok</dt> - <dd>The value should be true or false to allow or refuse hiatus (in the sense - of classical poetry). Default is false.</dd> - <dt>diaeresis</dt> - <dd>The value should be either "classical" to enforce an approximation of the - rules of classical verse or "permissive" to enforce a more permissive - approximations which will allow mostly all phonetically reasonable diérèses - and synérèses. Default is "classical".</dd> - <dt>forbidden_ok</dt> - <dd>The value should be true or false to allow or refuse patterns such as - "ées", "ies". Default is false. If you set this, it may be preferable to set - "diaeresis" to "permissive" so that the ambiguous patterns are counted - reasonably.</dd> - <dt>repeat_ok</dt> - <dd>If the value is false, the template will not repeat, and going beyond its - end will be an error. Default is true.</dd> - <dt>incomplete_ok</dt> - <dd>If the value is false, the poem should match the length of the template - (or a multiple thereof is repeat_ok was set), and not completing a template - run will be an error. Default is true.</dd> - <dt>phon_supposed_ok</dt> - <dd>Allow <em>liaison supposée</em> for rhymes (default is true).</dd> - <dt>eye_supposed_ok</dt> - <dd>Allow <em>liaison supposée</em> for <em>rimes pour l'œil</em> (default is - true).</dd> - <dt>eye_tolerance_ok</dt> - <dd>Allow tolerances for <em>rimes pour l'œil</em> such as "-é"/"-ai" (default - is true).</dd> - <dt>poor_eye_required</dt> - <dd>Require at least 2 characters in <em>rimes pour l'œil</em> when the sound - rhyme is poor (only one phoneme) and there are no monosyllabic words in the - rhyme (default is true, only applies to classical rhymes).</dd> - <dt>poor_eye_supposed_ok</dt> - <dd>Allow <em>liaison supposée</em> for the <em>rime pour l'œil</em> for - poor_eye_required (default is false).</dd> - <dt>poor_eye_vocalic_ok</dt> - <dd>Do not require the rhyme of poor_eye_required for successions of two - vocalic sounds (such as Noé/avoué).</dd> -</dl> - -<p>Sorry if all of this is a bit obscure.
