Methods
process
Do the bulk of the conversion work.
SmartQuotes
Quotes to entities.
SmartDashes
Call the individual dash conversion to entities functions.
SmartEllipses
Call the individual ellipse conversion to entities functions.
EducateQuotes
Parameter: String.
Returns: The string, with "educated" curly quote HTML entities.
Example input: "Isn't this fun?"
Example output: “Isn’t this fun?”
EducateBackticks
Replace double (back)ticks w/ HTML entities.
EducateSingleBackticks
Replace single (back)ticks w/ HTML entities.
EducateDashes
Dashes to HTML entity
Parameter: String.
Returns: The string, with each instance of "--" translated to
an em-dash HTML entity.
EducateDashesOldSchool
Dashes to entities.
Parameter: String.
Returns: The string, with each instance of "--" translated to
an en-dash HTML entity, and each "---" translated to
an em-dash HTML entity.
EducateDashesOldSchoolInverted
Parameter: String.
Returns: The string, with each instance of "--" translated to
an em-dash HTML entity, and each "---" translated to
an en-dash HTML entity. 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.)
EducateEllipses
Parameter: String.
Returns: The string, with each instance of "..." translated to
an ellipsis HTML entity.
Example input: Huh...?
Example output: Huh…?
StupefyEntities
Parameter: String.
Returns: The string, with each SmartyPants HTML entity translated to
its ASCII counterpart.
Example input: “Hello — world.”
Example output: "Hello -- world."
SmartyPantsVersion
Return the version of SmartyPants.
ProcessEscapes
Parameter: String.
Returns: The string, with after processing the following backslash
escape sequences. This is useful if you want to force a "dumb"
quote or other character to appear.

Name
Text::SmartyPants - cute little punctuation assistant
Synopsis
SmartyPants is a free web publishing plug-in for Movable Type, Blosxom, and BBEdit that
easily translates plain ASCII punctuation characters into "smart" typographic punctuation
HTML entities.
Description
SmartyPants can perform the following transformations:
• Straight quotes ( " and ' ) into "curly" quote HTML entities
• Backticks-style quotes (``like this'') into "curly" quote HTML entities
• Dashes ("--" and "---") into en- and em-dash entities
• Three consecutive dots ("...") into an ellipsis entity
This means you can write, edit, and save your posts using plain old ASCII straight quotes,
plain dashes, and plain dots, but your published posts (and final HTML output) will appear
with smart quotes, em-dashes, and proper ellipses.
SmartyPants is a combination plug-in -- the same file works with Movable Type, Blosxom,
and BBEdit. It can also be used from a Unix-style command-line. Version requirements and
installation instructions for each of these tools can be found in the corresponding sub-
section under "Installation", below.
SmartyPants does not modify characters within "<pre>", "<code>", "<kbd>", 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), 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.
MT-Textile Integration
Movable Type users should also note that SmartyPants can work in conjunction with Brad
Choate's MT-Textile plug-in:
http://bradchoate.com/past/mttextile.php
MT-Textile is a port of Dean Allen's original Textile project to Perl and Movable Type.
MT-Textile by itself only translates Textile markup to HTML. However, if SmartyPants is
also installed, MT-Textile will call on SmartyPants to educate quotes, dashes, and
ellipses, automatically. Using SmartyPants in conjunction with MT-Textile requires no
modifications to your Movable Type templates.
Textile is Dean Allen's "humane web text generator", an easy-to-write and easy-to-read
shorthand for writing text for the web. An online Textile web application is available at
Mr. Allen's site:
http://textism.com/tools/textile/
Installation
Movable Type
SmartyPants works with Movable Type version 2.5 or later.
1. Copy the "SmartyPants.pl" file into your Movable Type "plugins" directory. The
"plugins" directory should be in the same directory as "mt.cgi"; if it doesn't already
exist, use your FTP program to create it. Your installation should look like this:
(mt home)/plugins/SmartyPants.pl
2. If you're using SmartyPants with Brad Choate's MT-Textile, you're done.
If not, to activate SmartyPants on your weblog, you need to edit your MT templates.
The easiest way is to add the "smarty_pants" attribute to each MT template tag whose
contents you wish to apply SmartyPants' transformations. Obvious tags would include
"MTEntryTitle", "MTEntryBody", and "MTEntryMore". SmartyPants should work within any
MT content tag.
For example, to apply SmartyPants to your entry titles:
<$MTEntryTitle smarty_pants="1"$>
The value passed to "smarty_pants" specifies the way SmartyPants works. See
"Options", below, for full details on all of the supported options.
Blosxom
SmartyPants works with Blosxom version 2.0 or later.
1. Rename the "SmartyPants.pl" plug-in to "SmartyPants" (case is important). Movable Type
requires plug-ins to have a ".pl" extension; Blosxom forbids it (at least as of this
writing).
2. Copy the "SmartyPants" plug-in file to your Blosxom plug-ins folder. If you're not
sure where your Blosxom plug-ins folder is, see the Blosxom documentation for
information.
3. That's it. The entries in your weblog should now automatically have SmartyPants'
default transformations applied.
4. If you wish to configure SmartyPants' behavior, open the "SmartyPants" plug-in, and
edit the value of the $smartypants_attr configuration variable, located near the top
of the script. The default value is 1; see "Options", below, for the full list of
supported values.
BBEdit
SmartyPants works with BBEdit 6.1 or later on Mac OS X; and BBEdit 5.1 or later on Mac OS
9 or earlier (provided you have MacPerl installed).
1. Copy the "SmartyPants.pl" file to appropriate filters folder in your "BBEdit Support"
folder. On Mac OS X, this should be:
BBEdit Support:Unix Support:Unix Filters:
On Mac OS 9 or earlier, this should be:
BBEdit Support:MacPerl Support: Perl Filters:
See the BBEdit documentation for more details on the location of these folders.
You can rename "SmartyPants.pl" to whatever you wish.
2. That's it. To use SmartyPants, select some text in a BBEdit document, then choose
SmartyPants from the Filters sub-menu or the Filters floating palette. On Mac OS 9,
the Filters sub-menu is in the "Camel" menu; on Mac OS X, it is in the "#!" menu.
3. If you wish to configure SmartyPants' behavior, open the SmartyPants file and edit the
value of the $smartypants_attr configuration variable, located near the top of the
script. The default value is 1; see "Options", below, for the full list of supported
values.
Options
smarty_pants
For MT users, the "smarty_pants" template tag attribute is where you specify configuration
options. For Blosxom and BBEdit users, settings are specified by editing the value of the
$smartypants_attr variable in the script itself.
Numeric values are the easiest way to configure SmartyPants' behavior:
"0" Suppress all transformations. (Do nothing.)
"1" Performs default SmartyPants transformations: quotes (including ``backticks'' -style),
em-dashes, and ellipses. "--" (dash dash) is used to signify an em-dash; there is no
support for en-dashes.
"2" Same as smarty_pants="1", except that it uses the old-school typewriter shorthand for
dashes: "--" (dash dash) for en-dashes, "---" (dash dash dash) for em-dashes.
"3" Same as smarty_pants="2", but inverts the shorthand for dashes: "--" (dash dash) for
em-dashes, and "---" (dash dash dash) for en-dashes.
"-1"
Stupefy mode. Reverses the SmartyPants transformation process, turning the HTML
entities produced by SmartyPants into their ASCII equivalents. E.g. "“" is
turned into a simple double-quote ("), "—" is turned into two dashes, etc. This
is useful if you are using SmartyPants from Brad Choate's MT-Textile text filter, but
wish to suppress smart punctuation in specific MT templates, such as RSS feeds. Text
filters do their work before templates are processed; but you can use
smarty_pants="-1" to reverse the transformations in specific templates.
The following single-character attribute values can be combined to toggle individual
transformations from within the smarty_pants attribute. For example, to educate normal
quotes and em-dashes, but not ellipses or ``backticks'' -style quotes:
<$MTFoo smarty_pants="qd"$>
"q" Educates normal quote characters: (") and (').
"b" Educates ``backticks'' -style double quotes.
"B" Educates ``backticks'' -style double quotes and `single' quotes.
"d" Educates em-dashes.
"D" Educates em-dashes and en-dashes, using old-school typewriter shorthand: (dash dash)
for en-dashes, (dash dash dash) for em-dashes.
"i" Educates em-dashes and en-dashes, using inverted old-school typewriter shorthand:
(dash dash) for em-dashes, (dash dash dash) for en-dashes.
"e" Educates ellipses.
"w" Translates any instance of """ into a normal double-quote character. This should
be of no interest to most people, but of particular interest to anyone who writes
their posts using Dreamweaver, as Dreamweaver inexplicably uses this entity to
represent a literal double-quote character. SmartyPants only educates normal quotes,
not entities (because ordinarily, entities are used for the explicit purpose of
representing the specific character they represent). The "w" option must be used in
conjunction with one (or both) of the other quote options ("q" or "b"). Thus, if you
wish to apply all SmartyPants transformations (quotes, en- and em-dashes, and
ellipses) and also translate """ entities into regular quotes so SmartyPants can
educate them, you should pass the following to the smarty_pants attribute:
<$MTFoo smarty_pants="qDew"$>
For Blosxom and BBEdit users, set:
my $smartypants_attr = "qDew";
Deprecated MT Attributes
The following Movable Type attributes are supported only for compatibility with older
versions of SmartyPants. They are obsoleted by the "smarty_pants" attribute, which offers
more control than these individual attributes. If you're setting up SmartyPants for the
first time, you should use the "SmartyPants" attribute instead.
Blosxom and BBEdit users should simply ignore this section.
smart_quotes
The smart_quotes attribute accepts the following values:
"0" Suppress all quote education. (Do nothing.)
"1" Default behavior. Educates normal quote characters: (") and (').
"2" Educate ``backticks'' -style double quotes (in addition to educating regular quotes).
Transforms each instance of two consecutive backtick characters ("``") into an opening
double-quote, and each instance of two consecutive apostrophes ('') into a closing
double-quote.
smart_dashes
The smart_dashes attribute accepts the following values:
"0" Suppress dash education. (Do nothing.)
"1" Default behavior. Transforms each instance of "--" (dash dash) into an HTML entity-
encoded em-dash.
"2" Educates both en- and em-dashes, using the old-school typewriter shorthand for dashes.
Each instance of "--" (dash dash) is turned into an HTML entity-encoded en-dash; each
instance of "---" (dash dash dash) is turned into an em-dash.
"3" Same as smart_dashes="2", but inverts the shorthand, using "--" (dash dash) for em-
dashes, and "---" (dash dash dash) for en-dashes. Although somewhat counterintuitive
in that the longer shortcut is used for the shorter dash, this syntax is backwards
compatible with SmartyPants 1.0's original syntax, which used (dash dash) for em-
dashes.
smart_ellipses
The smart_ellipses attribute accepts the following values:
"0" Suppress ellipsis education. (Do nothing.)
"1" Default behavior. Transforms each instance of "..." (dot dot dot) into an HTML entity-
encoded ellipsis. If there are four consecutive dots, SmartyPants assumes this means
"full stop" followed by "ellipsis".
Version Info Tag
If you include this tag in a Movable Type template:
<$MTSmartyPantsVersion$>
it will be replaced with a string representing the version number of the installed version
of SmartyPants, e.g. "1.2".
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
HTML entities 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 HTML entities.
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:
the '80s
'Twas the night before Christmas.
In both cases above, SmartyPants will turn the apostrophes into opening single-quotes,
when in fact they should be closing ones. 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 ("’") by hand.
(I should also note that my personal style is to abbreviate decades like this:
the 80's
so admittedly, I'm not all that interested in solving this problem.)

This plug-in effectively obsoletes the technique documented here:
http://daringfireball.net/2002/08/movable_type_smart_quote_devilry.html
However, the above instructions may still be of interest if for some reason you are still
running an older version of Movable Type.
Version History
1.0: Wed Nov 13, 2002
Initial release.
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.
1.2: 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".
1.2.1: 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.
1.2.2: 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.
1.3: 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.
