SmartyPants can perform the following transformations: =over 4 =item * Straight quotes ( " and ' ) into "curly" quote HTML entities =item * Backticks-style quotes (``like this'') into "curly" quote HTML entities =item * Dashes (C<--> and C<--->) into en- and em-dash entities =item * Three consecutive dots (C<...>) into an ellipsis entity =back SmartyPants is a combination plug-in -- the same file works with Movable Type, Blosxom, BBEdit, and as a standalone Perl script. Version requirements and installation instructions for each of these tools can be found in the readme file that accompanies this script. SmartyPants does not modify characters within C<< <pre> >>, C<< <code> >>, C<< <kbd> >>, C<< <script> >>, or C<< <math> >> 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. =head2 Backslash Escapes If you need to use literal straight quotes (or plain hyphens and periods), SmartyPants accepts the following backslash escape sequences to force non-smart punctuation. It does so by transforming the escape sequence into a decimal-encoded HTML entity: Escape Value Character ------ ----- --------- \\ \ \ \" " " \' ' ' \. . . \- - - \` ` ` This is useful, for example, when you want to use straight quotes as foot and inch marks: 6'2" tall; a 17" iMac. =head1 OPTIONS Use "--" to end switch parsing. For example, to open a file named "-z", use: SmartyPants.pl -- -z =over 4 =item B<-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. =item B<-2> Same as B<-1>, except that it uses the old-school typewriter shorthand for dashes: '--' (dash dash) for en-dashes, '---' (dash dash dash) for em-dashes. =item B<-3> Same as B<-2>, but inverts the shorthand for dashes: '--' (dash dash) for em-dashes, and '---' (dash dash dash) for en-dashes. =item B<-v>, B<--version> Display SmartyPants's version number and copyright information. =item B<-s>, B<--shortversion> Display the short-form version number. =back =head1 BUGS To file bug reports or feature requests (other than topics listed in the Caveats section above) please send email to: smartypants@daringfireball.net If the bug involves quotes being curled the wrong way, please send example text to illustrate. =head2 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 single-quote, when in fact it should be a closing one. 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 use the proper HTML entity for closing single-quotes (C<’>) by hand. =head1 VERSION HISTORY 1.5.1: Fri 12 Mar 2004 + Fixed a goof where if you had SmartyPants 1.5.0 installed, but didn't have Markdown installed, when SmartyPants checked for Markdown's presence, it created a blank entry in MT's global hash of installed text filters. This showed up in MT's Text Formatting pop-up menu as a blank entry. 1.5: Tue 9 Mar 2004 + Integration with Markdown. If Markdown is already loaded when SmartyPants loads, SmartyPants will add a new global text filter, "Markdown With Smartypants". + Preliminary command-line options parsing. -1 -2 -3 -v -V + dot-space-dot-space-dot now counts as an ellipsis. This is the style used by Project Gutenberg: http://www.gutenberg.net/faq/index.shtml#V.110 (Thanks to Fred Condo for the patch.) + Added `<math>` to the list of tags to skip (pre, code, etc.). 1.4.1: Sat 8 Nov 2003 + The bug fix from 1.4 for dashes followed by quotes with no intervening spaces now actually works. + " " now counts as whitespace where necessary. (Thanks to Greg Knauss for the patch.) 1.4: Mon 30 Jun 2003 + Improved the HTML tokenizer so that it will parse nested <> pairs up to five levels deep. Previously, it only parsed up to two levels. What we *should* do is allow for any arbitrary level of nesting, but to do so, we would need to use Perl's ?? construct (see Fried's "Mastering Regular Expressions", 2nd Ed., pp. 328-331), and sadly, this would only work in Perl 5.6 or later. SmartyPants still supports Perl 5.00503. I suppose we could test for the version and build a regex accordingly, but I don't think I want to maintain two separate patterns. + Thanks to Stepan Riha, the tokenizer now handles HTML comments: <!-- comment --> and PHP-style processor instructions: <?php code ?> + The quote educator now handles situations where dashes are used without whitespace, e.g.: "dashes"--without spaces--"are tricky" + Special case for decade abbreviations like this: the '80s. This only works for the sequence appostrophe-digit-digit-s. 1.3: Tue 13 May 2003 + Plugged the biggest hole in SmartyPants's smart quotes algorithm. Previous versions were hopelessly confused by single-character quote tokens, such as: <p>"<i>Tricky!</i>"</p> The problem was that the EducateQuotes() function works on each token separately, with no means of getting surrounding context from the previous or next tokens. The solution is to curl these single-character quote tokens as a special case, *before* calling EducateQuotes(). + New single-quotes backtick mode for smarty_pants attribute. The only way to turn it on is to include "B" in the configuration string, e.g. to translate backtick quotes, dashes, and ellipses: smarty_pants="Bde" + Fixed a bug where an opening quote would get curled the wrong way if the quote started with three dots, e.g.: <p>"...meanwhile"</p> + Fixed a bug where opening quotes would get curled the wrong way if there were double sets of quotes within each other, e.g.: <p>"'Some' people."</p> + Due to popular demand, four consecutive dots (....) will now be turned into an ellipsis followed by a period. Previous versions would turn this into a period followed by an ellipsis. If you really want a period-then-ellipsis sequence, escape the first period with a backslash: \.... + Removed "&" from our home-grown punctuation class, since it denotes an entity, not a literal ampersand punctuation character. This fixes a bug where SmartyPants would mis-curl the opening quote in something like this: "…whatever" + SmartyPants has always had a special case where it looks for "'s" in situations like this: <i>Custer</i>'s Last Stand This special case is now case-insensitive. 1.2.2: Thu Mar 13, 2003 + 1.2.1 contained a boneheaded addition which prevented SmartyPants from compiling under Perl 5.005. This has been remedied, and is the only change from 1.2.1. 1.2.1: Mon Mar 10, 2003 + New "stupefy mode" for smarty_pants attribute. If you set smarty_pants="-1" SmartyPants will perform reverse transformations, turning HTML entities into plain ASCII equivalents. E.g. "“" is turned into a simple double-quote ("), "—" is turned into two dashes, etc. This is useful if you are using SmartyPants from Brad Choate's MT-Textile text filter, but wish to suppress smart punctuation in specific MT templates, such as RSS feeds. Text filters do their work before templates are processed; but you can use smarty_pants="-1" to reverse the transformations in specific templates. + Replaced the POSIX-style regex character class [:punct:] with an ugly hard-coded normal character class of all punctuation; POSIX classes require Perl 5.6 or later, but SmartyPants still supports back to 5.005. + Several small changes to allow SmartyPants to work when Blosxom is running in static mode. 1.2: Thu Feb 27, 2003 + SmartyPants is now a combination plug-in, supporting both Movable Type (2.5 or later) and Blosxom (2.0 or later). It also works as a BBEdit text filter and standalone command-line Perl program. Thanks to Rael Dornfest for the initial Blosxom port (and for the excellent Blosxom plug-in API). + SmartyPants now accepts the following backslash escapes, to force non-smart punctuation. It does so by transforming the escape sequence into a decimal-encoded HTML entity: Escape Value Character ------ ----- --------- \\ \ \ \" " " \' ' ' \. . . \- - - \` ` ` Note that this could produce different results than previous versions of SmartyPants, if for some reason you have an article containing one or more of these sequences. (Thanks to Charles Wiltgen for the suggestion.) + Added a new option to support inverted en- and em-dash notation: "--" for em-dashes, "---" for en-dashes. This is compatible with SmartyPants' original "--" syntax for em-dashes, but also allows you to specify en-dashes. It can be invoked by using smart_dashes="3", smarty_pants="3", or smarty_pants="i". (Suggested by Aaron Swartz.) + Added a new option to automatically convert " entities into regular double-quotes before sending text to EducateQuotes() for processing. This is mainly for the benefit of people who write posts using Dreamweaver, which substitutes this entity for any literal quote char. The one and only way to invoke this option is to use the letter shortcuts for the smarty_pants attribute; the shortcut for this option is "w" (for Dream_w_eaver). (Suggested by Jonathon Delacour.) + Added <script> to the list of tags in which SmartyPants doesn't touch the contents. + Fixed a very subtle bug that would occur if a quote was the very last character in a body of text, preceded immediately by a tag. Lacking any context, previous versions of SmartyPants would turn this into an opening quote mark. It's now correctly turned into a closing one. + Opening quotes were being curled the wrong way when the subsequent character was punctuation. E.g.: "a '.foo' file". Fixed. + New MT global template tag: <$MTSmartyPantsVersion$> Prints the version number of SmartyPants, e.g. "1.2". 1.1: Wed Feb 5, 2003 + The smart_dashes template attribute now offers an option to use "--" for *en* dashes, and "---" for *em* dashes. + The default smart_dashes behavior now simply translates "--" (dash dash) into an em-dash. Previously, it would look for " -- " (space dash dash space), which was dumb, since many people do not use spaces around their em dashes. + Using the smarty_pants attribute with a value of "2" will do the same thing as smarty_pants="1", with one difference: it will use the new shortcuts for en- and em-dashes. + Closing quotes (single and double) were incorrectly curled in situations like this: "<a>foo</a>", where the comma could be just about any punctuation character. Fixed. + Added <kbd> to the list of tags in which text shouldn't be educated. 1.0: Wed Nov 13, 2002 Initial release. =head1 AUTHOR John Gruber http://daringfireball.net =head1 ADDITIONAL CREDITS Portions of this plug-in are based on Brad Choate's nifty MTRegex plug-in.
