This will only work with AllegroCL + 6.2 if you've applied all patches with (SYS:UPDATE-ALLEGRO). + +1.3. You can also use ASDF instead of MK:DEFSYSTEM in a similar way + (use the .asd files instead of the .system files). + +1.4. For LispWorks there's a file 'lispworks-defsystem.lisp' which includes + a system definition for LispWork's Common Defsystem. + +2. Test + +CL-PPCRE comes with a test suite that can be used to check its +compatibility with Perl's regex syntax. See the documentation on how +to use this test suite for benchmarks and on how to write your own +tests. + +2.1. If you've used 'load.lisp' to load CL-PPCRE you already have the + test suite loaded and can start the default tests with + + (cl-ppcre-test:test) + +2.2. With MK:DEFSYSTEM you need to compile the 'cl-ppcre-test' system + as well before you can proceed as in 2.1. + +2.3. Same for ASDF. + +Depending on your machine and your CL implementation the default test +will take between a few seconds and a couple of minutes. (It will +print a dot for every tenth test case while it proceeds to give some +visual feedback.) It should exactly report three 'errors' (662, 790, +and 1439) which are explained in the documentation. + +MCL might report an error for the ninth test case which is also +explained in the docs. + +Genera notes (thanks to Patrick O'Donnell): Some more tests will fail +because characters like #\Return, #\Linefeed, or #\Tab have encodings +which differ from Perl's (and thus CL-PPCRE's) expectations.

(Well - as far as you can be +compatible with a language defined by its ever-changing +implementation. As of December 2002 CL-PPCRE was <a href="#perl">more +compatible</a> with the regex semantics of Perl&nbsp;5.8.0 than, say, +Perl&nbsp;5.6.1 was...) It even correctly parses and +applies <a href="http://www.oreilly.com/catalog/regex2/">Jeffrey +Friedl's</a> famous 6600-byte long RFC822 address pattern. + +<li>It is <b>fast</b>. Used with a Lisp compiler which compiles to +native code it is <a href="#performance">on par</a> with Perl's highly +optimized regex engine (written in C) which to my knowledge is faster +than most other regex engines around. + +<li>It is <b>portable</b>, i.e. the code aims to be strictly <a +href="http://www.lispworks.com/documentation/HyperSpec/Front/index.htm%22%3EANSI-c...</a>. If +you encounter any deviations, this is an error and should be +reported to <a +href="#mail">the mailing list</a>. CL-PPCRE has been +successfully tested with the following Common Lisp implementations: + +<ul> + +<li><a href="http://www.franz.com/products/allegrocl/">Allegro Common Lisp</a> +<li><a href="http://armedbear.org/abcl.html">Armed Bear Common Lisp</a> +<li><a href="http://clisp.sourceforge.net/">CLISP</a> +<li><a href="http://www.cons.org/cmucl/">CMUCL</a> +<li><a href="http://www.cormanlisp.com/">Corman Lisp</a> +<li><a href="http://ecls.sourceforge.net/">ECL</a> +<li><a href="http://www.symbolics.com/">Genera</a> +<li><a href="http://www.digitool.com/">Macintosh Common Lisp</a> +<li><a href="http://openmcl.clozure.com/">OpenMCL</a> +<li><a href="http://sbcl.sourceforge.net/">SBCL</a> +<li><a href="http://www.scieneer.com/scl/">Scieneer Common Lisp</a> +<li><a href="http://www.lispworks.com/">LispWorks</a> + +</ul> + +If you succeed in using CL-PPCRE on other platforms, please <a +href="#mail">let us know</a>. + +<br> +Note that the tests mainly made sure that the package compiled +without errors and that the <a href="#test">test suite</a> - which +compiles about 1,500 regex strings into scanners and applies these to +target strings with the <a href="#scan"><code>SCAN</code></a> function +- yields the expected results. Other functions like <a +href="#split"><code>SPLIT</code></a>, <a +href="#all-matches"><code>ALL-MATCHES</code></a>, <a +href="#regex-replace"><code>REGEX-REPLACE</code></a>, <a +href="#regex-apropos"><code>REGEX-APROPOS</code></a>, or <a +href="#do-scans">the <code>DO</code>-macros</a> have only been tested +on CMUCL and LispWorks which were my main development platforms. + +<br>Also, I don't have the time to re-test any implementation with +every new release of CL-PPCRE. <a href="#mail">Let us +know</a> if your implementation is listed above and fails with a +recent version and I'll try to fix it. + +<li>It is <b>thread-safe</b>. Although the code uses closures +extensively, no state which dynamically changes during the scanning +process is stored in the lexical environments of the closures, so it +should be safe to use CL-PPCRE in a multi-threaded program. Tests with +LispWorks and Scieneer Common Lisp seem to confirm this. + +<li>It comes with <b>convenient features</b> like a <a +href="#split"><code>SPLIT</code></a> function, a couple of <a +href="#do-scans"><code>DO</code>-like loop constructs</a>, and a <a +href="#regex-apropos"><code>regex-based APROPOS feature</code></a> +similar to the one found in <a +href="http://www.gnu.org/software/emacs/emacs.html%22%3EEmacs</a>. + +<li>In addition to specifying regular expressions as strings like in +Perl you can also use <a +href="#create-scanner2"><b>S-expressions</b></a> which obviously is +more Lisp-y. + +<li>Is it is fully <b>documented</b> so I might have a chance to +understand my own code in about six months... :) + +<li>It comes with a <a +href="http://www.opensource.org/licenses/bsd-license.php%22%3E<b>BSD-style +license</b></a> so you can basically do with it whatever you want. + +</ul> + +CL-PPCRE has been used successfully in various applications like <a +href="http://nostoc.stanford.edu/Docs/%22%3EBioBike</a>, +<a href="http://clutu.com/">clutu</a>, +<a

The second value is only returned if <a href="#*allow-named-registers*"><code>*ALLOW-NAMED-REGISTERS*</code></a> is <i>true</i>. It represents a list of strings mapping registers to their respective names - the first element stands for first register, the second element for second register, etc. You have to store this value if you want to map a register number to its name later as <i>scanner</i> doesn't capture any information about register names. If a register isn't named, it has NIL as its name. +<p> +The mode keyword arguments are equivalent to the +<code>&quot;imsx&quot;</code> modifiers in Perl. The +<code>destructive</code> keyword will be ignored. +<p> +The function accepts most of the regex syntax of Perl 5 as described +in <a +href="http://perldoc.perl.org/perlre.html%22%3E<code>man +perlre</code></a> including extended features like non-greedy +repetitions, positive and negative look-ahead and look-behind +assertions, &quot;standalone&quot; subexpressions, and conditional +subpatterns.

Names are case-sensitive and don't need to be unique. See <a href="#*allow-named-registers*"><code>*ALLOW-NAMED-REGISTERS*</code></a> for details. + + +<li><code>(:BACK-REFERENCE &lt;<i>ref</i>&gt;)</code> is a +back-reference to a register group. <code>&lt;<i>ref</i>&gt;</code> is +a positive integer or a string denoting a register name. If there are +several registers with the same name, the regex engine tries to +successfully match at least of them, starting with the most recently +seen register continuing to the least recently seen one, until a match +is found. See <a +href="#*allow-named-registers*"><code>*ALLOW-NAMED-REGISTERS*</code></a> +for more information. + +<li><a class=none name="filterdef"><code>(:FILTER &lt;<i>function</i>&gt; <tt>&amp;optional</tt> +&lt;<i>length</i>&gt;)</code></a> where +<code>&lt;<i>function</i>&gt;</code> is a <a +href="http://www.lispworks.com/documentation/HyperSpec/Body/26_glo_f.htm#function_... +designator</a> and <code>&lt;<i>length</i>&gt;</code> is a +non-negative integer or <code>NIL</code> is a user-defined <a +href="#filters">filter</a>. + +<li><code>(:REGEX &lt;<i>string</i>&gt;)</code> where +<code>&lt;<i>string</i>&gt;</code> is an +embedded <a href="#create-scanner">regular expression in Perl +syntax</a>. + +<li><code>(:CHAR-CLASS|:INVERTED-CHAR-CLASS +{&lt;<i>item</i>&gt;}*)</code> where <code>&lt;<i>item</i>&gt;</code> +is either a character, a <em>character range</em>, or a symbol for a +special character class (see above) will be translated into a (one +character wide) character class. A <em>character range</em> looks like +<code>(:RANGE &lt;<i>char1</i>&gt; &lt;<i>char2</i>&gt;)</code> where +<code>&lt;<i>char1</i>&gt;</code> and +<code>&lt;<i>char2</i>&gt;</code> are characters such that +<code>(CHAR&lt;= &lt;<i>char1</i>&gt; &lt;<i>char2</i>&gt;)</code> is +true.

To +circumvent this you can always use the equivalent parse tree <code>(:GROUP +&lt;<i>string</i>&gt;)</code> instead. +<p> +Note that <code>CREATE-SCANNER</code> doesn't always check +for the well-formedness of its first argument, i.e. you are expected +to provide <em>correct</em> parse trees. + +<p> +The usage of the keyword argument <code>extended-mode</code> obviously +doesn't make sense if <code>CREATE-SCANNER</code> is applied to parse +trees and will signal an error. +<p> +If <code>destructive</code> is not <code>NIL</code> (the default is +<code>NIL</code>), the function is allowed to destructively modify +<code><i>parse-tree</i></code> while creating the scanner. +<p> +If you want to find out how parse trees are related to Perl regex +strings, you should play around with +<code>CL-PPCRE::PARSE-STRING</code> - a function which converts Perl +regex strings to parse trees.

Filters can only be used within <a +href="#create-scanner2">parse trees</a>, not within Perl regex +strings. +<p> +A filter is defined by its <em>filter function</em> which must be a +function of one argument. During the parsing process this function +might be called once or several times or it might not be called at +all. If it's called, its argument is an integer <code><i>pos</i></code> +which is the current position within the target string. The filter can +either return <code>NIL</code> (which means that the subexpression +represented by this filter didn't match) or an integer not smaller +than <code><i>pos</i></code> for success. A zero-length assertion +should return <code><i>pos</i></code> itself while a filter which +wants to consume <code>N</code> characters should return +<code>(+&nbsp;POS&nbsp;N)</code>. +<p> +If you supply the optional value <code><i>length</i></code> and it is +not <code>NIL</code>, then this is a promise to the regex engine that +your filter will <em>always</em> consume <em>exactly</em> +<code><i>length</i></code> characters. The regex engine might use this +information for optimization purposes but it is otherwise irrelevant +to the outcome of the matching process. +<p> +The filter function can access the following special variables from +its code body: +<ul> + +<li><code>CL-PPCRE::*STRING*</code>: The target (a string) of the +current matching process. + +<li><code>CL-PPCRE::*START-POS*</code> and +<code>CL-PPCRE::*END-POS*</code>: The start and end (integers) indices +of the current matching process. These correspond to the +<code>START</code> and <code>END</code> keyword parameters of <a +href="#scan"><code>SCAN</code></a>. + +<li><code>CL-PPCRE::*REAL-START-POS*</code>: The initial starting +position. This is only relevant for repeated scans (as in <a +href="#do-scans"><code>DO-SCANS</code></a>) where +<code>CL-PPCRE::*START-POS*</code> will be moved forward while +<code>CL-PPCRE::*REAL-START-POS*</code> won't. For normal scans the +value of this variable is <code>NIL</code>. + +<li><CODE>CL-PPCRE::*REG-STARTS*</CODE> and +<CODE>CL-PPCRE::*REG-ENDS*</CODE>: Two simple vectors which denote the +start and end indices of registers within the regular expression.

if it can reduce significant +parts of the matching process to cases where it can advance through +the target string one character at a time. This leads to C code where +you can very efficiently test and increment a pointer into a string in +a tight loop and can hardly be beaten with CL. In almost all other +cases, the CMUCL/CL-PPCRE combination is usually faster than Perl - +sometimes a lot faster. +<p> +As most of the examples above were chosen to make Perl look good +here's <a href="benchmarks.2002-12-22.txt">another benchmark</a> - the +result of running <a href="#test"><code>perltest.pl</code></a> against the +full <a href="#test"><code>testdata</code></a> file with a time +limit of 0.1 seconds, CL-PPCRE&nbsp;0.1.2 on CMUCL&nbsp;18e-pre +vs. Perl&nbsp;5.6.1. CL-PPCRE is faster than Perl in 1511 of 1545 +cases - in 1045 cases it's more than twice as fast. +<p> +Note that Perl as well as CL-PPCRE keep the rightmost matches in +registers - keep that in mind if you benchmark against other regex +implementations. Also note that <code>CL-PPCRE-TEST:TEST</code> +automatically skips test cases where Perl and CL-PPCRE don't agree. + +<h4><a name="other" class=none>Other performance issues</a></h4> + +While the scanners created by CL-PPCRE are pretty fast, the process +which creates scanners from Perl regex strings and parse trees isn't +that speedy and conses a lot. It is recommended that you store and +re-use scanners if possible. The <code>DO-</code>macros will do this +for you automatically. +<p> +However, beginning with version&nbsp;0.5.2, CL-PPCRE uses a <a +name="compiler-macro" +href="http://www.lispworks.com/documentation/HyperSpec/Body/26_glo_c.htm#compiler_... +macro</a> and <a +href="http://www.lispworks.com/documentation/HyperSpec/Body/s_ld_tim.htm%22%3E<code>LOAD-TIME-VALUE</code></a> +to make sure that the scanner is only built once if the first argument +to <a href="#scan"><code>SCAN</code></a>, <a href="#scan-to-strings"><code>SCAN-TO-STRINGS</code></a>, <a href="#split"><code>SPLIT</code></a>, +<a href="#regex-replace"><code>REGEX-REPLACE</code></a>, or <a href="#regex-replace-all"><code>REGEX-REPLACE-ALL</code></a> is a <a +href="http://www.lispworks.com/documentation/HyperSpec/Body/26_glo_c.htm#constant_... +form</a>.

The most important rule is probably that you shouldn't use +capturing groups if you don't need the captured information, i.e. use +<code>&quot;(?:a|b)*&quot;</code> instead of +<code>&quot;(a|b)*&quot;</code> if you don't need to refer to the +register. (In fact, in this particular case CL-PPCRE will be able to +optimize away the register group, but it won't if you replace +<code>&quot;a|b&quot;</code> with, say, +<code>&quot;a|bc&quot;</code>.) +<p> +Another point worth mentioning is that you definitely should use +single-line mode if you have long strings without +<code>#\Newline</code> (or where you don't care about the line breaks) +and plan to use regular expressions like +<code>&quot;.*&quot;</code>. See the <a href="#bench">benchmarks</a> +for comparisons between single-line mode and normal mode with such +target strings. +<p> +Another thing to consider is that, for performance reasons, CL-PPCRE +assumes that most of the target strings you're trying to match are <a +href="http://www.lispworks.com/documentation/HyperSpec/Body/t_smp_st.htm%22%3Esimp... +strings</a> and coerces non-simple strings to simple strings before +scanning them. If you plan on working with non-simple strings mostly, +you might consider modifying the CL-PPCRE source code. This is easy: +Change all occurences of <code>SCHAR</code> to <code>CHAR</code> and +redefine the macro in <code>util.lisp</code> where the coercion takes +place - that's all. + +<br>&nbsp;<br><h3><a name="bugs" class=none>Bugs and problems</a></h3> + +<h4><a name="stack" class=none>Stack overflow</a></h4> + +CL-PPCRE can optimize away a lot of unnecessary backtracking but +sometimes this simply isn't possible.

This cannot happen in Perl due to its +complicated interpolation rules - see <code>man&nbsp;perlop</code> for +the scary details. It <em>can</em> happen in CL-PPCRE, though. +Bummer! +<p> +What gives? <code>&quot;\Q...\E&quot;</code> in CL-PPCRE should only +be used in literal strings.

Shouldn't something like <code>(CL-PPCRE:SCAN&nbsp;A&nbsp;A)</code> always return a true value? No, because the first and the second argument to <code>SCAN</code> are handled differently: The first argument is fed to CL-PPCRE's parser and is treated like a Perl regular expression. In particular, the parser "sees" <code>\y</code> and converts it to <code>y</code> because <code>\y</code> has no special meaning in regular expressions. So, the regular expression is the constant string <code>"yy"</code>. But the second argument isn't converted - it is left as is, i.e. it's equivalent to Perl's <code>'y\y'</code>. In other words, this example would be equivalent to the Perl code + +<pre> +'y\y' =~ /y\y/; +</pre> + +or to + +<pre> +$a = 'y\y'; +$a =~ /$a/; +</pre> + +which should explain why it doesn't match. +<p> +Still confused?

Although CL-PPCRE is quite fast already, AllegroCL's engine will +most likely be even faster (but only on AllegroCL, of course). However, you might want to +stick to CL-PPCRE because you have a "legacy" application or because +you want your code to be portable to other Lisp implementations. +Therefore, beginning from version 1.2.0, CL-PPCRE offers a +"compatibility mode" where you can continue using the CL-PPCRE API as +described <a href="#dict">above</a> but deploy the AllegroCL regex +engine under the hood. (The details are: Calls to <a +href="#create-scanner"><code>CREATE-SCANNER</code></a> and <a +href="#scan"><code>SCAN</code></a> are dispatched to their AllegroCL +counterparts <a +href="http://www.franz.com/support/documentation/7.0/doc/operators/excl/compile-re...<code>EXCL:COMPILE-RE</code></a> +and <a +href="http://www.franz.com/support/documentation/7.0/doc/operators/excl/match-re.h...<code>EXCL:MATCH-RE</code></a> +while everything else is left as is.) +<p> +The advantage of this mode is that you'll get a much smaller image and +most likely faster code. (But note that CL-PPCRE needs to do a small amount of work to massage AllegroCL's output into the format expected by CL-PPCRE.) The downside is that your code won't be +fully compatible with CL-PPCRE anymore. Here are some of the +differences (most of which probably don't matter very often): +<ul> +<li>The AllegroCL engine doesn't offer <a +href="#parse-tree-synonym">parse tree synonyms</a> and <a href="#filters">filters</a>. +<li>The AllegroCL engine <a href="http://www.franz.com/support/documentation/7.0/doc/regexp.htm#regexp-new-compatibility-2">will choke on some regular expressions involving curly braces</a> that are accepted by Perl and CL-PPCRE's native engine. +<li>The AllegroCL engine's case-folding mode switch (which is used instead of CL-PPCRE's <a href="#create-scanner"><code>:CASE-INSENSITIVE</code> keyword parameter</a>) <a href="http://www.franz.com/support/documentation/7.0/doc/regexp.htm#regexp-new-matching-2">is currently only effective for ASCII characters</a>. +<li>The AllegroCL engine <a href="http://www.franz.com/support/documentation/7.0/doc/regexp.htm#regexp-new-compatibility-2">doesn't support</a> <a href="#*allow-quoting*">quoting of metacharacters</a>. +<li>In AllegroCL compatibility mode compiled regular expressions (as returned by <a href="#create-scanner"><code>CREATE-SCANNER</code></a>) aren't functions but structures. +</ul> +For more details about the AllegroCL engine and possible deviations from CL-PPCRE see the <a href="http://www.franz.com/support/documentation/7.0/doc/regexp.htm">documentation</a> at the <a href="http://www.franz.com/">Franz Inc. website</a>. +<p> +To use the AllegroCL compatibility mode you have to +<pre> +(push :use-acl-regexp2-engine *features*) +</pre> +<em>before</em> you compile CL-PPCRE. + +<br>&nbsp;<br><h3><a class=none name="ack">Acknowledgements</a></h3> + +Although I didn't use their code I was heavily inspired by looking at +the Scheme/CL regex implementations of <a +href="http://www.ccs.neu.edu/home/dorai/pregexp/pregexp.html%22%3EDorai +Sitaram</a> and <a +href="http://www.geocities.com/mparker762/clawk#regex%22%3EMichael +Parker</a>.

As a +stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking +(both directions), persistent connections (keep-alive), and SSL, but +it can also sit behind the +popular <a href='http://httpd.apache.org/'>Apache</a> using +Marc +Battyani's <a +href='http://www.fractalconcept.com/asp/html/mod_lisp.html%27%3Emod_lisp</a>. + +<p> + +Hunchentoot provides facilities like automatic session handling (with +and without cookies), logging (to Apache's log files or to a file in +the file system), customizable error handling, and easy access to GET +and POST parameters sent by the client. It does <em>not</em> include +functionality to programmatically generate HTML output. For this task +you can use any library you like, e.g. (shameless +self-plug) <a href="http://weitz.de/cl-who/">CL-WHO</a> +or <a href="http://weitz.de/html-template/">HTML-TEMPLATE</a>. + +<p> + +Hunchentoot talks with its front-end or with the client over TCP/IP +sockets and uses multiprocessing to handle several requests at the +same time. Therefore, it cannot be implemented completely +in <a +href="http://www.lispworks.com/documentation/HyperSpec/Front/index.htm%22%3Eportab... +Common Lisp</a>. It currently works with +<a href="http://www.lispworks.com/">LispWorks</a> (which is the main development and testing platform), +<a href="http://www.cons.org/cmucl/">CMUCL</a> (with MP +support), <a href="http://sbcl.sourceforge.net/">SBCL</a> (with +Unicode and <a href="http://abstractstuff.livejournal.com/26811.html">thread</a> <a href="http://common-lisp.net/pipermail/tbnl-devel/2006-November/000780.html">support</a>), +<a href="http://openmcl.clozure.com/">OpenMCL</a>, +and <a href="http://www.franz.com/products/allegrocl/">Allegro Common +Lisp</a>. (Note: You can use Hunchentoot with a version of SBCL +without threads, for example on Windows, but this is not recommended +except for development purposes.) Porting to other CL implementations +shouldn't be too hard, see the files <code>port-xxx.lisp</code> +and <code>unix-xxx.lisp</code> which comprise all the +implementation-specific code. + +<p> + +Hunchentoot comes with a <a +href="http://www.opensource.org/licenses/bsd-license.php%22%3EBSD-style +license</a> so you can basically do with it whatever you want. +<p> + +Hunchentoot is for example used by <a href="http://clutu.com/">clutu</a>, <a href="http://twitterbuzz.com/">TwitterBuzz</a>, +<a href="http://www.jalat.com/">Jalat</a>, <a href="http://heikestephan.de/">Heike Stephan</a>, +<a href="http://www.memetrics.com/">xOs</a>, +and <a href="http://syseng.nist.gov/moss">the</a> <a href="http://syseng.nist.gov/se-interop">NIST</a>. + +<p> +<font color=red>Download shortcut:</font> <a href="http://weitz.de/files/hunchentoot.tar.gz">http://weitz.de/files/hunchentoot.tar.gz</a>. +</blockquote> + +<br>&nbsp;<br><h3><a class=none name="contents">Contents</a></h3> +<ol> + <li><a href="#install">Download and installation</a> + <ol> + <li><a href='#proxy'>Hunchentoot behind a proxy</a> + <li><a href='#mod_lisp'>Hunchentoot behind mod_lisp</a> + </ol> + <li><a href="#mail">Support and mailing lists</a> + <li><a href="#example">Examples, tutorials, add-ons</a> + <li><a href="#reference">Function and variable reference</a> + <ol> + <li><a href='#servers'>Servers</a> + <li><a href='#handlers'>Handlers</a> + <li><a href='#requests'>Requests</a> + <li><a href='#replies'>Replies</a> + <li><a href='#cookies'>Cookies</a> + <li><a href='#sessions'>Sessions</a> + <li><a href='#log'>Logging and error handling</a> + <li><a href='#debug'>Debugging Hunchentoot applications</a> + <li><a href='#misc'>Miscellaneous</a> + </ol> + <li><a href="#ht-mp">The HUNCHENTOOT-MP package</a> + <li><a href="#performance">Performance</a> + <li><a href="#history">History</a> + <li><a href="#index">Symbol index</a> + <li><a href="#ack">Acknowledgements</a> +</ol> + +<br>&nbsp;<br><h3><a name="install" class=none>Download and installation</a></h3> + +Hunchentoot depends on a couple of other Lisp libraries which you'll need +to install first: +<ul> + <li>Pierre R.

One approach that I have used several times is to employ +Apache's <a +href="http://httpd.apache.org/docs/2.0/mod/mod_proxy.html%22%3Emod_proxy</a> +module with a configuration that looks like this: +<pre> +<a href="http://httpd.apache.org/docs/2.0/mod/mod_proxy.html#proxypass" class=noborder>ProxyPass</a> /hunchentoot http://127.0.0.1:3000/hunchentoot +<a href="http://httpd.apache.org/docs/2.0/mod/mod_proxy.html#proxypassreverse" class=noborder>ProxyPassReverse</a> /hunchentoot http://127.0.0.1:3000/hunchentoot +</pre> +This will tunnel all requests where the URI path begins with <code>"/hunchentoot"</code> to a (Hunchentoot) server listening on port&nbsp;3000 on the same machine. +<p> +Of course, there are <a href="http://www.red-bean.com/pipermail/lispweb/2006-October/001342.html">several other</a> (more lightweight) web proxies that +you could use instead of Apache. + +<h4><a name="mod_lisp" class=none>Hunchentoot behind mod_lisp</a></h4> + +You can also couple Hunchentoot more tightly with Apache +using <a +href='http://www.fractalconcept.com/asp/html/mod_lisp.html%27%3Emod_lisp</a>. +In this case, Apache will not send proxy requests to Hunchentoot, but +communicate with it directly using a simple, line-based protocol. The +downside of this approach is that it makes debugging harder. (Also, +with mod_lisp, +you <a +href="http://common-lisp.net/pipermail/mod-lisp-devel/2006-October/000098.html%22%... +accept request bodies that use chunked encoding</a>. With the usual +web browsers, this shouldn't be a problem, though.) +<p> +For this setup you need two things: + +<ul> + <li>The <a href='http://httpd.apache.org/'>Apache web server</a>. You can use either 1.3.x or 2.x. It is recommend that you use or build an Apache with <a href='http://httpd.apache.org/docs/dso.html'>DSO support</a>. + + <li>The <a +href='http://www.fractalconcept.com/asp/html/mod_lisp.html%27%3Emod_lisp</a> +Apache module by Marc Battyani. It is beyond the scope of this document to explain the +details of how to install mod_lisp, but if your Apache has DSO support, +it should suffice to issue a command like + +<pre> +apxs -c -i -a mod_lisp.c +</pre> + +as root (and afterwards restart Apache). +<p> +The newest version of mod_lisp is available from <a +href="http://www.fractalconcept.com:8000/public/open-source/mod_lisp/%22%3Ehttp://...</a>. For Apache&nbsp;1.3.x you +must use mod_lisp.c, for Apache&nbsp;2.x you must use mod_lisp2.c, which is a reimplementation of Marc's mod_lisp by Chris Hanson. +<p> +You can get pre-compiled modules for the Win32 version of Apache&nbsp;2 (but probably not the latest version) from <a href="http://www.fractalconcept.com:8000/public/open-source/mod_lisp/windows/">http://www.fractalconcept.com:8000/public/open-source/mod_lisp/windows/</a>. Put the file into Apache's <code>modules</code> folder and add the line +<pre> +LoadModule lisp_module modules/mod_lisp2.so +</pre> +to your <code>httpd.conf</code> file. + +</ul> + +Then you will have to configure Apache and mod_lisp to make them aware +of Hunchentoot. First, in your Apache configuration file (usually +called <code>httpd.conf</code>) add these lines + +<pre> +<a name='LispServer' class=noborder>LispServer</a> 127.0.0.1 3000 &quot;foo&quot; + +&lt;Location /hunchentoot&gt; + SetHandler lisp-handler +&lt;/Location&gt; +</pre> + +and afterwards restart Apache. This informs mod_lisp that there's a +Lisp listening on port&nbsp;3000 and named +&quot;foo&quot; - you can of course use any other name or port or +even put Hunchentoot on another physical machine. (In the latter case you'll +have to replace <code>127.0.0.1</code> with the FQDN or IP address of +this machine.) +<p> +The <code>Location/SetHandler</code> part means that every URL which +starts with <code>/hunchentoot</code> will be handled by mod_lisp (and thus +Hunchentoot) on this server. (Again, you can of course use other locations. See the +Apache documentation for things like <em>virtual hosts</em> or +directives like <code>LocationMatch</code>.) + +<p> + +To interface a Hunchentoot server with mod_lisp, you must start it +with the <code>:MOD-LISP-P</code> keyword parameter +of <a href="#start-server"><code>START-SERVER</code></a> set to a true +value. + +<br>&nbsp;<br><h3><a name="mail" class=none>Support and mailing lists</a></h3> + +For questions, bug reports, feature requests, improvements, or patches +please use +the <a +href="http://common-lisp.net/mailman/listinfo/tbnl-devel%22%3Etbnl-devel +mailing list</a>.

The array, +which will become the value of <code><i>var</i></code>, will be big +enough to hold all matching parameters, but not bigger. Array +elements not set as described above will be <code>NIL</code>. Note +that <code>VAR</code> will always be bound to an array, which may be +empty, so it will never be <code>NIL</code>, even if no appropriate +GET/POST parameters are found. +<p> +The full form of a <code>'HASH-TABLE</code> parameter type is + +<pre> + (hash-table inner-type key-type test-function), +</pre> + +but <code><i>key-type</i></code> and <code><i>test-function</i></code> +can be left out in which case they default to <code>'STRING</code> +and <code>'EQUAL</code>, respectively. For this parameter type, all +GET/POST parameters which have a name like the result of + +<pre> + (format nil "~A{~A}" real-name key) +</pre> + +(where <code><i>key</i></code> is a string that doesn't contain curly brackets) will +become the values (after conversion to <code><i>inner-type</i></code>) of a hash +table with test function <code><i>test-function</i></code> where <code><i>key</i></code> (after +conversion to <code><i>key-type</i></code>) will be the corresponding key. Note that +<code><i>var</i></code> will always be bound to a hash table, which +may be empty, so it will never be <code>NIL</code>, even if no +appropriate GET/POST parameters are found. +<p> +To make matters even more complicated, the three compound parameter +types also have an abbreviated form - just one of the +symbols <code>LIST</code>, <code>ARRAY</code>, +or <code>HASH-TABLE</code>.

As I had no immediate plans to release +my code (which was poorly organized, undocumented, and mostly +CMUCL-specific), I gave it to Jeff and he worked towards a release. He +added docstrings, refactored, added some stuff, and based it on KMRCL +to make it portable across several Lisp implementations. +<p> +Unfortunately, Jeff is at least as busy as I am so he didn't find the +time to finish a full release. But in spring&nbsp;2004 I needed a +documented version of the code for a client of mine who thought +it would be good if the toolkit were publicly available under an open +source license. So I took Jeff's code, refactored again (to sync with +the changes I had done in the meantime), and added documentation. +This resulted in TBNL&nbsp;0.1.0 (which initially required mod_lisp as its +front-end). Jeff's code (which includes a lot more stuff that I +didn't use) is still available from his own +website <a href='http://tbnl.org/'>tbnl.org</a>. +<p> +In March&nbsp;2005, Bob Hutchinson sent patches which enabled TBNL to use +other front-ends than mod_lisp. This made me aware that TBNL was +already <em>almost</em> a full web server, so eventually I wrote +Hunchentoot which <em>was</em> a full web server, implemented as a +wrapper around TBNL. Hunchentoot&nbsp;0.1.0 was released at the end of +2005 and was originally LispWorks-only. +<p> +Hunchentoot&nbsp;0.4.0, released in October&nbsp;2006, was the first release +which also worked with other Common Lisp implementations. It is a +major rewrite and also incorporates most of TBNL and replaces +it completely. + +<br>&nbsp;<br><h3><a class=none name="index">Symbol index</a></h3> + +Here are all exported symbols of the

If REAL-NAME is +not provided, it will be computed by downcasing the symbol name +of VAR. + +If URI (which is evaluated) is provided, then it must be a string or +a function designator for a function of one argument. In this case, +the handler will be returned by DISPATCH-EASY-HANDLERS, if URI is a +string and the script name of a request is URI, or if URI designates a +function and applying this function to the current request object +returns a true value. + +SERVER-NAMES (which is evaluated) can be a list of symbols which +means that the handler will be returned by DISPATCH-EASY-HANDLERS in +servers which have one of these names (see SERVER-NAME). +SERVER-NAMES can also be the symbol T which means that the handler +will be returned by DISPATCH-EASY-HANDLERS in every server. + +Whether the GET or POST parameter (or both) will be taken into +consideration, depends on REQUEST-TYPE which can +be :GET, :POST, :BOTH, or NIL. In the last case, the value of +DEFAULT-REQUEST-TYPE (the default of which is :BOTH) will be +used. + +The value of VAR will usually be a string (unless it resulted from a +file upload in which case it won't be converted at all), but if +PARAMETER-TYPE (which is evaluated) is provided, the string will be +converted to another Lisp type by the following rules: + +If the corresponding GET or POST parameter wasn't provided by the +client, VAR's value will be NIL. If PARAMETER-TYPE is 'STRING, VAR's +value remains as is. If PARAMETER-TYPE is 'INTEGER and the parameter +string consists solely of decimal digits, VAR's value will be the +corresponding integer, otherwise NIL. If PARAMETER-TYPE is 'KEYWORD, +VAR's value will be the keyword obtained by interning the upcased +parameter string into the keyword package. If PARAMETER-TYPE is +'CHARACTER and the parameter string is of length one, VAR's value will +be the single character of this string, otherwise NIL. If +PARAMETER-TYPE is 'BOOLEAN, VAR's value will always be T (unless it +is NIL by the first rule above, of course). If PARAMETER-TYPE is any +other atom, it is supposed to be a function designator for a unary +function which will be called to convert the string to something else. + +Those were the rules for `simple' types, but PARAMETER-TYPE can +also be a list starting with one of the symbols LIST, ARRAY, or +HASH-TABLE. The second value of the list must always be a simple +parameter type as in the last paragraph - we'll call it the +`inner type' below. + +In the case of 'LIST, all GET/POST parameters called REAL-NAME +will be collected, converted to the inner type, and assembled +into a list which will be the value of VAR. + +In the case of 'ARRAY, all GET/POST parameters which have a name +like the result of + + (format nil "~A[~A]" real-name n) + +where N is a non-negative integer, will be assembled into an +array where the Nth element will be set accordingly, after +conversion to the inner type. The array, which will become the +value of VAR, will be big enough to hold all matching parameters, +but not bigger. Array elements not set as described above will +be NIL. Note that VAR will always be bound to an array, which +may be empty, so it will never be NIL, even if no appropriate +GET/POST parameters are found. + +The full form of a 'HASH-TABLE parameter type is + + (hash-table inner-type key-type test-function), + +but KEY-TYPE and TEST-FUNCTION can be left out in which case they +default to 'STRING and 'EQUAL, respectively. For this parameter +type, all GET/POST parameters which have a name like the result +of + + (format nil "~A{~A}" real-name key) + +(where KEY is a string that doesn't contain curly brackets) will +become the values (after conversion to INNER-TYPE) of a hash +table with test function TEST-FUNCTION where KEY (after +conversion to KEY-TYPE) will be the corresponding key. Note that +VAR will always be bound to a hash table, which may be empty, so +it will never be NIL, even if no appropriate GET/POST parameters +are found. + +To make matters even more complicated, the three compound +parameter types also have an abbreviated form - just one of the +symbols LIST, ARRAY, or HASH-TABLE. In this case, the inner type +will default to 'STRING. + +If PARAMETER-TYPE is not provided or NIL, DEFAULT-PARAMETER-TYPE +(the default of which is 'STRING) will be used instead. + +If the result of the computations above would be that VAR would +be bound to NIL, then INIT-FORM (if provided) will be evaluated +instead, and VAR will be bound to the result of this evaluation. + +Handlers built with this macro are constructed in such a way that +the resulting Lisp function is useful even outside of +Hunchentoot.
