باختصار

مقالة عن قصيدة لكيتس كما تطبعها مجلة أدبية. يكتب المؤلف رمزًا قصيرًا لكل مصدر، فيطبع Postext المؤلف والصفحة بين قوسين وقائمة الأعمال المستشهد بها في آخر المقالة، على أسلوب MLA.

ما الذي ستنضده

مقالة من مجلة أدبية فصلية: أربع صفحات عمّن ينطق البيتين الأخيرين من قصيدة كيتس "Ode on a Grecian Urn". الصفحة صفحة مجلة قياسها 150 × 230 mm منضَّدة بخط Spectral، وعناوين الأقسام والترويسات بخط Spectral SC، وصفحة الافتتاح في شريط بلون الطلاء الأسود فوق شريط بلون الطين الأحمر، وهما لونا الإناء الأتّيكي. تتبع الاستشهادات أسلوب MLA 9، أسلوب معظم أقسام الأدب وتاريخ الفن: المؤلف والصفحة بين قوسين، والصفحة وحدها حين تذكر الجملة اسم المؤلف، وعنوان مختصر حين يشترك عملان في مؤلف واحد، وقائمة Works Cited في صفحة خاصة بها. كل استشهاد مفتاح في النص، والأسلوب إعداد واحد.

طريقة التحضير

#1 · الأسلوب MLA والبيانات CSL

الكود هو الجواب المختصر أعلاه. يُسجَّل محرّك الاستشهادات مرة واحدة، ويسمّي citations.style أسلوب MLA المرفق؛ ومنه يكتب citeproc-js كل استشهاد والقائمة. توجد المراجع في كتلة :::references{format=csl-yaml} في آخر المقالة. تُستعمل CSL-YAML هنا بدل BibTeX لأن MLA يحتاج إلى عنوان مختصر لعملَي كيتس، وقارئ BibTeX في postext 1.12.1 يُسقط الحقل shorttitle؛ واسم الحقل في CSL هو title-short.

#2 · ثلاثة أنواع من الاستشهاد

يستشهد النص بعمل بالصيغة [@jack1967]، فتُطبع "(Jack)" لأن المقالة تحيل إلى الكتاب كله. ومع رقم صفحة تطبع [@keats-letters, 41] العبارة "(Keats, Letters 41)": فالمقالة تستشهد بعملين لكيتس، فيضيف citeproc العنوان المختصر للتمييز بينهما. وحين تذكر الجملة الناقدَ باسمه، تُسقط [-@eliot1932, 230] الاسم وتطبع "(230)". وبعد أن يُستشهد بالقصيدة مع أرقام أبياتها، تحمل الاقتباسات اللاحقة منها الأرقام وحدها، مكتوبة بين قوسين عاديين، كما يسمح MLA.

#3 · اقتباس كتلي يأتي استشهاده بعد النقطة

script.js · الأسطر 48–52في الكود الكامل
// More than four lines of prose go in a Markdown blockquote: in ink, indented, with no
// first-line indent. Its citation follows the final full stop, as MLA asks.
const blockquote = {
  color: col('ink'), italic: false, indent: em(2), firstLineIndent: em(0),
};

تمتد الرسالة عن Negative Capability إلى أكثر من أربعة أسطر من النثر، فتُفصل اقتباسًا كتليًا في Markdown: بحروف قائمة، وبلون الحبر، ومُزاحة بمقدار 2 em بلا مسافة بادئة للسطر الأول. يضع MLA استشهاد الاقتباس الكتلي بعد نقطته الأخيرة، ويفعل المصدر الشيء نفسه: …fact and reason. [@keats-letters, 48]. ويفصل :::space{lines=0.5} فوقه وتحته الاقتباسَ عن الفقرات المحيطة به.

#4 · قائمة Works Cited في صفحة خاصة بها

script.js · السطر 119في الكود الكامل
  headingStyles: [{ id: 'works-cited', breakBefore: { enabled: true, parity: 'any' } }],

يأخذ العنوان نمطًا ينتقل إلى صفحة جديدة، ويضع :::bibliography{title=""} القائمة تحته من غير عنوان ثانٍ. القائمة مرتبة أبجديًا بمسافة بادئة معلَّقة، ويبدأ العمل الثاني لكيتس بشَرطة بطول ثلاثة em مكان اسمه، كما يطلب MLA للمؤلفين المكرَّرين. ويُطبع رقم صفحة سفلي في ذيل هذه الصفحة وصفحة الافتتاح، حيث تغيب الترويسات.

#5 · صفحة افتتاح بلونَي إناء

const markdown = String.raw`---
نموذج Markdown · أسطر: 95 · content.en.mdtitle: "Cold Pastoral" author: "Helena Ward" --- # Cold Pastoral {#essay kicker="Essays · Romantic Poetry" sub="On the voice in the last two lines of Keats’s “Ode on a Grecian Urn”" byline="Helena Ward"} No Greek urn answers to the one Keats describes. Readers who went looking for it in the British Museum found parts of several: the heifer led to sacrifice on the Parthenon frieze, which Keats saw among the Elgin Marbles in the spring of 1817, and the Bacchic dancers of the Townley Vase, with those of the Borghese Vase in the Louvre, known in London through engravings [@jack1967]. The nearest thing to a single source is a sheet of paper. Keats traced an engraving of the Sosibios Vase, a marble krater signed by an Athenian sculptor of the first century BCE, from Henry Moses’s book of antique vases, and the tracing survives [@mcdermott1948]. The urn of the poem is a composite, assembled from marbles and from prints of marbles, and at the end it speaks. Keats wrote the ode in May 1819. It was first printed in January 1820 in the *Annals of the Fine Arts*, a London magazine about painting and sculpture, and that summer he collected it in his third and last book of poems. The two printings differ in one mark of punctuation, and much of what has been written about the poem since turns on that mark. ## The questions The ode opens by naming its object three times, as a “still unravish’d bride of quietness,” a “foster-child of silence and slow time” and a “Sylvan historian” [@keats-ode, lines 1–3]. The names are a courtesy: the speaker wants the historian to tell its tale. “What men or gods are these? What maidens loth? / What mad pursuit? What struggle to escape?” (8–9). The urn does not answer, and for three stanzas the speaker answers for it, praising the “unheard” melodies of the painted pipes over heard ones (11–12) and a lover who will never reach the girl but will always love her. The fourth stanza turns from the dancers to a procession, a priest leading a heifer “lowing at the skies” (33), and then to a town that is not on the urn at all, emptied of its people by the sacrifice and left silent “for evermore” (38). Here the questions stop being answerable even in principle. The town exists only because the procession has to have come from somewhere. ## The punctuation of the last lines In the last stanza the speaker gives up questioning. The urn “dost tease us out of thought / As doth eternity: Cold Pastoral!” (44–45), and it will outlast this generation as “a friend to man, to whom thou say’st, / ‘Beauty is truth, truth beauty,’—that is all / Ye know on earth, and all ye need to know” (48–50). In the 1820 volume the inverted commas close after “beauty,” so the urn says five words and someone else says the rest. The *Annals* text has no inverted commas, and neither have the transcripts made by Keats’s friends [@stillinger1974]. An editor has to choose, and the choice decides who says “that is all”: the urn to mankind, the poet to his reader, or the poet to the figures on the urn. The lines have had hostile readers. T. S. Eliot found the couplet “a serious blemish on a beautiful poem” [-@eliot1932, 230], a statement that was either untrue or one he could not understand. Cleanth Brooks answered that the words are “a speech ‘in character’” [-@brooks1947, 165], fitted to the urn that utters them, and set them beside Edgar’s “Ripeness is all” in *King Lear*. His reading needs the 1820 punctuation: if the urn speaks only the five words inside the commas, the motto is the urn’s, and the comment after the dash belongs to the poet who has listened to it. ## The letters Keats had written about beauty and truth before he wrote about the urn. “What the Imagination seizes as Beauty must be truth—whether it existed before or not,” he told Benjamin Bailey in November 1817 [@keats-letters, 41]. A month later, walking home from the Christmas pantomime, he named the quality he thought a poet most needed: :::space{lines=0.5} > I had not a dispute, but a disquisition, with Dilke upon various subjects; several things dove-tailed in my mind, and at once it struck me what quality went to form a Man of Achievement, especially in Literature, and which Shakspeare possessed so enormously—I mean Negative Capability, that is, when a man is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason. [@keats-letters, 48] :::space{lines=0.5} Read with the letter beside it, the couplet is less a doctrine than a refusal. The urn has answered none of the speaker’s questions about who the figures are or where the town stands. What it offers instead is a sentence that cannot be checked, and the poet’s comment accepts that this is all the urn will give. The speaker who began by demanding a tale ends content with half knowledge, which is the state the letter asks a poet to bear. ## Works Cited {style="works-cited"} :::bibliography{title=""} :::paragraphs{style="colophon"} Set in Spectral and Spectral SC (SIL OFL).

أخطاء شائعة

خطأ شائع

أي كائن headings يُلغي فاصل الصفحة قبل H1

ينتقل H1 افتراضيًا إلى صفحة فردية (always-odd)، لكن تمرير أي كائن headings يعيد ضبط هذا الافتراض، فتتوالى الفصول دون فاصل ولا يفعل span: 'page' شيئًا. أعد كتابة headings.levels[0].breakBefore: { enabled: true, parity } في كل إعداد. فصول تبدأ في صفحة فردية →

خطأ شائع

حمّل كل أوجه الخط قبل الإخراج

يقيس الإخراج النص بأوجه الخط التي حمّلها المتصفح ويخزّن العروض مؤقتًا، فالوجه الذي يصل بعد البناء الأول يترك فواصل أسطر خاطئة وملف PDF لم يعد يطابق الشاشة. حمّل كل وزن وكل نمط أولًا، واستدعِ clearMeasurementCache() قبل إعادة البناء إذا تأخر وصول أحدها. الخطوط قبل الإخراج →

خطأ شائع

لوحة الألوان المستبدلة لا تصل إلى عناصر التصميم ولا إلى لون الإحالة

يقرأ postext 1.4.1 الإعداد colorPalette في أنماط النص (المتن والعناوين والقوائم والتعليقات والجداول والإطارات) لكن لا في عناصر الترويسات والتذييلات والافتتاحيات وصفحات الأجزاء، ولا في bodyText.referenceColor: تحتفظ بالقيمة الست عشرية المكتوبة بجانب paletteId الخاص بها. حين تستبدل لوحة الألوان، لنسخة شاشة داكنة أو لإعادة تلوين، أعِد كتابة كل لون مرتبط من colorPalette قبل البناء. لوحة ألوان دلالية →

يخزّن المحرّك الإعدادات المحسوبة مؤقتًا بحسب هوية الكائن، فتعديل الإعداد في مكانه ثم البناء مجددًا يعيد استخدام النتيجة القديمة. ابنِ كائنًا جديدًا في كل بناء، ولهذا يكون إعداد الوصفة دالة مصنِّعة: config(). صفحات على اللوحة (Canvas) →

  • الاستشهاد السردي بلا صفحة، @stillinger1974 records، يطبع الاسم وبعده مسافة ثانية في postext 1.12.1. استشهد بعمل كهذا بين قوسين في آخر العبارة كما تفعل هذه المقالة، أو أعطِ رقم صفحة.
  • يطبع citeproc-js العناوين كما تعطيها البيانات. يستعمل MLA الأحرف الكبيرة في أوائل كلمات العناوين الإنجليزية (title case)، فاكتبها كذلك في المراجع.
