Adapted to Docutils_ by Günter Milde. Additional Credits ================== Portions of the SmartyPants original work are based on Brad Choate's nifty MTRegex plug-in. `Brad Choate`_ also contributed a few bits of source code to this plug-in. Brad Choate is a fine hacker indeed. `Jeremy Hedley`_ and `Charles Wiltgen`_ deserve mention for exemplary beta testing of the original SmartyPants. `Rael Dornfest`_ ported SmartyPants to Blosxom. .. _Brad Choate: http://bradchoate.com/ .. _Jeremy Hedley: http://antipixel.com/ .. _Charles Wiltgen: http://playbacktime.com/ .. _Rael Dornfest: http://raelity.org/ Copyright and License ===================== SmartyPants_ license (3-Clause BSD license): Copyright (c) 2003 John Gruber (http://daringfireball.net/) All rights reserved.

SmartyPants does not modify characters within ``<pre>``, ``<code>``, ``<kbd>``, ``<math>`` or ``<script>`` tag blocks. Typically, these tags are used to display text where smart quotes and other "smart punctuation" would not be appropriate, such as source code or example markup. Backslash Escapes ================= If you need to use literal straight quotes (or plain hyphens and periods), `smartquotes` accepts the following backslash escape sequences to force ASCII-punctuation. Mind, that you need two backslashes as Docutils expands it, too. ======== ========= Escape Character ======== ========= ``\\`` \\ ``\\"`` \\" ``\\'`` \\' ``\\.`` \\. ``\\-`` \\- ``\\``` \\` ======== ========= This is useful, for example, when you want to use straight quotes as foot and inch marks: 6\\'2\\" tall; a 17\\" iMac. Caveats ======= Why You Might Not Want to Use Smart Quotes in Your Weblog --------------------------------------------------------- For one thing, you might not care. Most normal, mentally stable individuals do not take notice of proper typographic punctuation. Many design and typography nerds, however, break out in a nasty rash when they encounter, say, a restaurant sign that uses a straight apostrophe to spell "Joe's". If you're the sort of person who just doesn't care, you might well want to continue not caring. Using straight quotes -- and sticking to the 7-bit ASCII character set in general -- is certainly a simpler way to live. Even if you *do* care about accurate typography, you still might want to think twice before educating the quote characters in your weblog. One side effect of publishing curly quote characters is that it makes your weblog a bit harder for others to quote from using copy-and-paste. What happens is that when someone copies text from your blog, the copied text contains the 8-bit curly quote characters (as well as the 8-bit characters for em-dashes and ellipses, if you use these options). These characters are not standard across different text encoding methods, which is why they need to be encoded as characters. People copying text from your weblog, however, may not notice that you're using curly quotes, and they'll go ahead and paste the unencoded 8-bit characters copied from their browser into an email message or their own weblog. When pasted as raw "smart quotes", these characters are likely to get mangled beyond recognition. That said, my own opinion is that any decent text editor or email client makes it easy to stupefy smart quote characters into their 7-bit equivalents, and I don't consider it my problem if you're using an indecent text editor or email client. Algorithmic Shortcomings ------------------------ One situation in which quotes will get curled the wrong way is when apostrophes are used at the start of leading contractions. For example:: 'Twas the night before Christmas. In the case above, SmartyPants will turn the apostrophe into an opening secondary quote, when in fact it should be the `RIGHT SINGLE QUOTATION MARK` character which is also "the preferred character to use for apostrophe" (Unicode). I don't think this problem can be solved in the general case -- every word processor I've tried gets this wrong as well. In such cases, it's best to inset the `RIGHT SINGLE QUOTATION MARK` (’) by hand. In English, the same character is used for apostrophe and closing secondary quote (both plain and "smart" ones). For other locales (French, Italean, Swiss, ...) "smart" secondary closing quotes differ from the curly apostrophe. .. class:: language-fr Il dit : "C'est 'super' !" If the apostrophe is used at the end of a word, it cannot be distinguished from a secondary quote by the algorithm. Therefore, a text like:: .. class:: language-de-CH "Er sagt: 'Ich fass' es nicht.'" will get a single closing guillemet instead of an apostrophe. This can be prevented by use use of the `RIGHT SINGLE QUOTATION MARK` in the source:: - "Er sagt: 'Ich fass' es nicht.'" + "Er sagt: 'Ich fass’ es nicht.'"

(Do nothing.) :1: Performs default SmartyPants transformations: quotes (including \`\`backticks'' -style), em-dashes, and ellipses. "``--``" (dash dash) is used to signify an em-dash; there is no support for en-dashes :2: Same as smarty_pants="1", except that it uses the old-school typewriter shorthand for dashes: "``--``" (dash dash) for en-dashes, "``---``" (dash dash dash) for em-dashes. :3: Same as smarty_pants="2", but inverts the shorthand for dashes: "``--``" (dash dash) for em-dashes, and "``---``" (dash dash dash) for en-dashes. :-1: Stupefy mode. Reverses the SmartyPants transformation process, turning the characters produced by SmartyPants into their ASCII equivalents. E.g. the LEFT DOUBLE QUOTATION MARK (“) is turned into a simple double-quote (\"), "—" is turned into two dashes, etc. The following single-character attribute values can be combined to toggle individual transformations from within the smarty_pants attribute. For example, ``"1"`` is equivalent to ``"qBde"``. :q: Educates normal quote characters: (") and ('). :b: Educates \`\`backticks'' -style double quotes. :B: Educates \`\`backticks'' -style double quotes and \`single' quotes. :d: Educates em-dashes. :D: Educates em-dashes and en-dashes, using old-school typewriter shorthand: (dash dash) for en-dashes, (dash dash dash) for em-dashes. :i: Educates em-dashes and en-dashes, using inverted old-school typewriter shorthand: (dash dash) for em-dashes, (dash dash dash) for en-dashes. :e: Educates ellipses. :w: Translates any instance of ``"`` into a normal double-quote character. This should be of no interest to most people, but of particular interest to anyone who writes their posts using Dreamweaver, as Dreamweaver inexplicably uses this entity to represent a literal double-quote character. SmartyPants only educates normal quotes, not entities (because ordinarily, entities are used for the explicit purpose of representing the specific character they represent). The "w" option must be used in conjunction with one (or both) of the other quote options ("q" or "b"). Thus, if you wish to apply all SmartyPants transformations (quotes, en- and em-dashes, and ellipses) and also translate ``"`` entities into regular quotes so SmartyPants can educate them, you should pass the following to the smarty_pants attribute: """ default_smartypants_attr = "1" import re, sys class smartchars(object): """Smart quotes and dashes """ endash = u'–' # "–" EN DASH emdash = u'—' # "—" EM DASH ellipsis = u'…' # "…" HORIZONTAL ELLIPSIS apostrophe = u'’' # "’" RIGHT SINGLE QUOTATION MARK # quote characters (language-specific, set in __init__()) # [1] http://en.wikipedia.org/wiki/Non-English_usage_of_quotation_marks # [2] http://de.wikipedia.org/wiki/Anf%C3%BChrungszeichen#Andere_Sprachen # [3] https://fr.wikipedia.org/wiki/Guillemet # [4] http://typographisme.net/post/Les-espaces-typographiques-et-le-web # [5] http://www.btb.termiumplus.gc.ca/tpv2guides/guides/redac/index-fra.html # [6] https://en.wikipedia.org/wiki/Hebrew_punctuation#Quotation_marks # [7] http://www.tustep.uni-tuebingen.de/bi/bi00/bi001t1-anfuehrung.pdf # [8] http://www.korrekturavdelingen.no/anforselstegn.htm # [9] Typografisk håndbok.

Two reasons why: First, unlike the en- and em-dash syntax supported by EducateDashesOldSchool(), it's compatible with existing entries written before SmartyPants 1.1, back when "--" was only used for em-dashes. Second, em-dashes are more common than en-dashes, and so it sort of makes sense that the shortcut should be shorter to type. (Thanks to Aaron Swartz for the idea.)
