NAME

       HTML::Template::Compiled - Template System Compiles HTML::Template files to Perl code

VERSION

       $VERSION = "1.001"

SYNOPSIS

         use HTML::Template::Compiled;
         # recommended options:
         # case_sensitive => 1
         # search_path_on_include => 1
         # use_query => 0
         # default_escape => 'HTML' # <-- HIGHLY RECOMMENDED

         # note that the following
         # use HTML::Template::Compiled speed => 1
         # is deprecated (can be problematic under persistent environments)

         # or for the biggest compatibility with HTML::Template
         # case_sensitive => 0
         # search_path_on_include => 0
         # use_query => 1
         # note that the following
         # use HTML::Template::Compiled compatible => 1;
         # is deprecated (can be problematic under persistent environments)

         # or use HTML::Template::Compiled::Classic

           my $htc = HTML::Template::Compiled->new(
               filename            => 'test.tmpl',
               case_sensitive      => 1,
               default_escape      => 'HTML',
           );
           $htc->param(
               BAND => $name,
               ALBUMS => [
                   { TITLE => $t1, YEAR => $y1 },
                   { TITLE => $t2, YEAR => $y2 },
               ],
           );
           print $htc->output;

         test.tmpl:
         Band: <TMPL_VAR BAND>
         <TMPL_LOOP ALBUMS>
         Title: <TMPL_VAR TITLE> (<TMPL_VAR YEAR>)
         </TMPL_LOOP>

         Or use different tag styles:
         Band: <%= BAND %>
         <%loop ALBUMS %>
         Title: <%= TITLE %> (<%= YEAR %>)
         <%/loop %>
         Band: [%= BAND %]
         [%loop ALBUMS %]
         Title: [%= TITLE %] ([%= YEAR %])
         [%/loop %]

DESCRIPTION

       HTML::Template::Compiled is a template system which can be used for HTML::Template
       templates with almost the same API. It offers more flexible template delimiters,
       additional tags and features, and by compiling the template into perl code it can run
       significantly faster in persistent environments such as FastCGI or mod_perl.

       The goal is to offer more features for flexibility but keep the basic syntax as easy as it
       is.

       Features at a glance:

       Dot notation for objects, hashes and arrays
       Use expressions without any disadvantages like those in HTML::Template::Expr
       Write escaping plugins and plugins for new tags
       Alternate delimiters, e.g. "[%if %]" and "<%if %>"
       Avoid "global_vars" option by using the "SET_VAR" tag to create aliases.
       Tags ELSIF, EACH, WHILE, COMMENT, WRAPPER, SWITCH/CASE, INCLUDE_VAR
       Chomp newlines/whitespace

       For a quick reference, see HTML::Template::Compiled::Reference.

       As the basic features work like in HTML::Template, please get familiar with its
       documentation before.

       HTML::Template::Compiled (HTC) does not implement all features of HTML::Template (see
       "COMPATIBILITY"), and it has got some additional features which are explained below:
       "ADDITIONAL FEATURES"

       See "BENCHMARKS" for some examples on the performance. Since it depends highly on the
       options used and on the template size there can be no general statement on its
       performance.

       You might want to use HTML::Template::Compiled::Lazy for CGI environments as it doesn't
       parse the template before calling output. But note that HTC::Lazy isn't much tested, and I
       don't use it myself, so there's a lack of experience.  If you use it and have problems,
       please report.

       HTC will use a lot of memory because it keeps all template objects in memory.  If you are
       on mod_perl, and have a lot of templates, you should preload them at server startup to be
       sure that it is in shared memory. At the moment HTC is not fully tested for keeping all
       data in shared memory (e.g. when a copy-on-write occurs), but it seems like it's behaving
       well.  For preloading you can use
         HTML::Template::Compiled->preload($cache_dir).

       Generating code, writing it on disk and later eval() it can open security holes, for
       example if you have more users on the same machine that can access the same files (usually
       an http server running as 'www' or 'nobody'). See "SECURITY" for details what you can do
       to safe yourself.

       NOTE: If you don't need any of the additional features listed below and if you don't need
       the speed (in many cases it's probably not worth trading speed for memory), then you might
       be better off with just using HTML::Template.

       NOTE2: If you have any questions, bug reports, send them to me and not to Sam Tregar.
       This module is developed by me at the moment, independently from HTML::Template, although
       I try to get most of the tests from it passing for HTC. See "RESOURCES" for current
       information.

   FEATURES FROM HTML::TEMPLATE
       TMPL_VAR
       TMPL_LOOP
       TMPL_(IF|UNLESS|ELSE)
       TMPL_INCLUDE
       HTML_TEMPLATE_ROOT
       ESCAPE=(HTML|URL|JS|0)
       DEFAULT=...
       "__first__", "__last__", "__inner__", "__outer__", "__odd__", "__counter__", "__even__"
       <!-- TMPL_VAR NAME=PARAM1 -->
       case insensitive var names
           use option case_sensitive => 0 to use this feature (slow down)

       filters
       vars that are subrefs - not implemented, only in HTML::Template::Compiled::Classic
       scalarref, arrayref, filehandle
       "global_vars"
       "query"
           Has a bug (doesn't return parameters in included files of included files).  I'm
           working on that.

   ADDITIONAL FEATURES
       What can HTC do for you additionally to HTML::Template?

       tag TMPL_ELSIF
           No need to have cascading "if-else-if-else"s

       tag TMPL_EACH
           Iterate over a hash. See "TMPL_EACH"

       tag TMPL_WITH
           see "TMPL_WITH"

       tag TMPL_WHILE
           see "TMPL_WHILE"

       tag TMPL_SET_VAR
           see "SET_VAR"

       tag TMPL_USE_VARS
           see "USE_VARS"

       tags TMPL_COMMENT, TMPL_NOPARSE, TMPL_VERBATIM
           see "TMPL_COMMENT", "TMPL_NOPARSE", "TMPL_VERBATIM"

       tag TMPL_WRAPPER
           see "WRAPPER"

       "__index__"
           Additional loop variable ("__counter__ -1")

       "__break__"
           Additional loop variable (see "TMPL_LOOP")

       "__filename__", "__filenameshort__" (since 0.91_001)
           Insert the template filename for debugging:

               <%= __filename__ %>
               <%= __filenameshort__ %>

           will turn out as:
               templates/path/file.html
               path/file.html

           See also option debug_file in "OPTIONS" for adding the filename globally.

       tags TMPL_SWITCH, TMPL_CASE
           see "TMPL_SWITCH"

       "TMPL_PERL"
           Include perl code in your template. See "RUNNING PERL WITH TMPL_PERL"

       CHOMP
           New in version 0.96_001, please report any bugs and send me suggestions.

           You can set global chomp options in the constructor. These work like in Template-
           Toolkit:

               my $htc = HTML::Template::Compiled->new(
                   pre_chomp  => 0, # 0, 1, 2, 3, default 0
                   post_chomp => 1, # 0, 1, 2, 3, default 0
               );

           Meaning of the values: 0: Don't chomp 1: remove only spaces in the line before or
           after the tag 2: remove all whitespaces before or after the tag, and replace with one
           space 3: remove all whitespaces before or after the tag

           In the template you can change that feature by using PRE_CHOMP and POST_CHOMP
           attributes:

               <%= foo PRE_CHOMP=3 POST_CHOMP=1 %>

           The experimental tags +..._chomp have been removed.

       Generating perl code
           See "IMPLEMENTATION"

       better variable access
           dot-notation for accessing hash values. See "EXTENDED VARIABLE ACCESS"

       rendering objects
           dot-notation for accessing object methods. See "RENDERING OBJECTS"

       output to filehandle
           See "OPTIONS"

       Dynamic includes
           "INCLUDE_VAR", "INCLUDE_STRING". See "INCLUDE"

       tag TMPL_IF_DEFINED
           Check for definedness instead of truth:
             <TMPL_IF_DEFINED NAME="var">

       ALIAS
           Set an alias for a loop variable. You can use the alias then with $alias.  The syntax
           without the "$" is also possible but not recommended any more.

           For example, these two loops are functionally equivalent:

            <tmpl_loop foo>
              <tmpl_var _>
            </tmpl_loop foo>
            <tmpl_loop foo alias=current>
              <tmpl_var $current>
            </tmpl_loop foo>

           This works with "TMPL_LOOP" and "TMPL_WHILE" at the moment.

           You can also set aliases with the "SET_VAR" tag. See "SET_VAR"

           To use template parameters with a "$" at the beginning (which is not officially
           supported, but some are obviously using it), you can set:

               local $HTML::Template::Compiled::Compiler::DISABLE_NEW_ALIAS = 1;

           This is only a temporary workaround and will be removed some day!

           Note that you are also able to access variables with dollar signs like this:

               <tmpl_var _.$foo >

           since underscore means current position in the parameter stash, and aliases are only
           recognized at the beginning of a template var. But note that dollar signs are still
           not officially supported.

       Chained escaping
           See "ESCAPING"

       tagstyles
           For those who like it (i like it because it is shorter than TMPL_), you can use <% %>
           tags and the <%= tag instead of <%VAR (which will work, too):

            <%IF blah%>  <%= VARIABLE%>  <%/IF%>

           Define your own tagstyles and/or deactivate predefined ones.  See "OPTIONS" tagstyle.

       pre_chomp, post_chomp
           See "CHOMP"

   MISSING AND DIFFERENT FEATURES
       There are some features of H::T that are missing or behaving different.  I'll try to list
       them here.

       MISSING FEATURES

       die_on_bad_params
           I don't think I'll implement that.

       force_untaint
           Not planned at the moment

       vanguard_compatibility_mode
           Not planned.

       shared_cache, double_cache
           Not planned at the moment

       blind_cache
           Not sure if I should implement. In HTC you have the possibility to set the expire time
           of the templates (after that time in memory the template file is rechecked if it has
           changed), so setting a very high value for expire_time would have the same effect as
           blind_cache.  See "CACHING" "expire_time"

       double_file_cache
           If I understand correctly, in HT, this enables memory and file cache at the same time.
           In HTC, this is not needed. If you use file_cache and cache, both are used.

       file_cache_dir_mode
           Not planned. The cache dir must exist, and subdirectories are not created at the
           moment.

       cache_lazy_vars, cache_lazy_loops
           Not planned at the moment (This would be for HTML::Template::Compiled::Classic, since
           it implements code refs).

       utf8
           Might be added in the future, HTC already has "open_mode"

       various debug options
           Might be implemented in the future

       associate
           Not planned.

       max_includes
           Not planned

       die_on_missing_include
           Maybe

       DIFFERENT FEATURES

       case_sensitive
           default is 1 (on).

           Deactivate by passing option case_sensitive 0.

           Note (again): this will slow down templating a lot (50%).

           Explanation: This has nothing to do with "TMPL_IF" or "tmpl_if". It's about the
           variable names. With case_sensitive set to 1, the following tags are different:

               <tmpl_var Foo> prints the value of hash key 'Foo'
               <tmpl_var fOO> prints the value of hash key 'fOO'

           With case_sensitive set to 0, all your parameters passed to "param()" are converted to
           lowercase, and the following tags are the same:

               <tmpl_var Foo> prints the value of hash key 'foo'
               <tmpl_var fOO> prints the value of hash key 'foo'

       subref variables
           As of version 0.69, subref variables are not supported any more with
           HTML::Template::Compiled. Use HTML::Template::Compiled::Classic (contained in this
           distribution) instead. It provides most features of HTC.

       search_path_on_include
           Default: 0

           In the HTML::Template documentation it says, if search_path_on_include is set to 1,
           the paths of the path option are searched, while the default behaviour is to look
           "only" in the current template directory.

           It's not clear if it still searches in the current directory if set to 1. I found out
           that it is not, so you cannot have both.

           In HTML::Template::Compiled, search_path_on_include can have three values:
               0: search current template directory
               1: search paths specified
               2: search paths and current template directory.

       open_mode
           In HTC you should leave out the "<" at the beginning.

           If you want to have your templates read in utf-8, use

               open_mode => ':encoding(utf-8)',

           as an option.

       use_query
           default is 0 (off). Set it via the option "use_query"

       Arrayrefs
           At the moment this snippet

             <tmpl_if arrayref>true<tmpl_else>false</tmpl_if arrayref>

           with this code:

               $htc->param(arrayref => []);

           will print true in HTC and false in HTML::Template. In HTML::Template an array is true
           if it has content, in HTC it's true if it (the reference) is defined. I'll try to find
           a way to change that behaviour, though that might be for the cost of speed.

           As of HTML::Template::Compiled 0.85 you can use this syntax:

               <tmpl_if arrayref# >true<tmpl_else>false</tmpl_if >

           In HTML::Template::Compiled::Classic 0.04 it works as in HTML::Template.

       debug_cache
           Additional to 0 or 1 it can take an array ref for debugging only specific cache
           operations.

       Note: the following is deprecated:

           To be compatible in all of the above options all use:

             use HTML::Template::Compiled compatible => 1;

           If you don't care about these options you should use

             use HTML::Template::Compiled speed => 1;

        which is the default but depending on user wishes that might change.

   DEPRECATED
       class methods ExpireTime, EnableSub, CaseSensitive, SearchPathOnInclude, UseQuery
       option formatter_path
       tag USE_VARS, not needed anymore
       option cache_dir (replaced by file_cache_dir)
       options method_call, deref, default_path, dumper
       import tags short, compatible, speed

   ESCAPING
       Like in HTML::Template, you have "ESCAPE=HTML", "ESCAPE=URL" and "ESCAPE_JS".
       "ESCAPE=HTML" will only escape '"&<>. If you want to escape more, use "ESCAPE=HTML_ALL".
       Additionally you have "ESCAPE=DUMP", which by default will generate a Data::Dumper output.

       You can also chain different escapings, like "ESCAPE=DUMP|HTML".

       Additionally to ESCAPE=JS you have ESCAPE=IJSON which does not escape the single quote.

   INCLUDE
       Additionally to

         <TMPL_INCLUDE NAME="file.htc">

       you can do an include of a template variable:

         <TMPL_INCLUDE_VAR NAME="file_include_var">
         $htc->param(file_include_var => "file.htc");

       Using "INCLUDE VAR="..."" is deprecated.

       You can also include strings:

           template:
           inc: <%include_string foo %>

           code:
           $htc->param(
               foo => 'included=<%= bar%>',
               bar => 'real',
           );

           output:
           inc: included=real

       Note that included strings are not cached and cannot include files or strings themselves.

   EXTENDED VARIABLE ACCESS
       With HTC, you have more control over how you access your template parameters. An example:

         my %hash = (
           SELF => '/path/to/script.pl',
           LANGUAGE => 'de',
           BAND => 'Bauhaus',
           ALBUMS => [
           {
             NAME => 'Mask',
             SONGS => [ { NAME => 'Hair of the Dog' }, ... ],
           },
           ],
           INFO => {
             BIOGRAPHY => '...',
             LINK => '...'
           },
           NAME => "Cool script",
         );

       Now in the TMPL_LOOP "ALBUMS" you would like to access the path to your script, stored in
       $hash{SELF}. in HTML::Template you have to set the option "global_vars", so you can access
       $hash{SELF} from everywhere. Unfortunately, now "NAME" is also global, which might not a
       problem in this simple example, but in a more complicated template this is impossible.
       With HTC, you wouldn't use "global_vars" here, but you can say:

         <TMPL_VAR .SELF>

       to access the root element, and you could even say ".INFO.BIOGRAPHY" or
       "ALBUMS[0].SONGS[0].NAME" (the latter has changed since version 0.79)

   RENDERING OBJECTS
       This is still in development, so I might change the API here.

       Additionally to feeding a simple hash to HTC, you can feed it objects.  To do method calls
       you can also use '.' in the template.

         my $htc = HTML::Template::Compiled->new(
           ...
         );

         $htc->param(
           VAR => "blah",
           OBJECT => bless({...}, "Your::Class"),
         );

         <TMPL_VAR NAME="OBJECT.fullname">
         <TMPL_WITH OBJECT>
         Name: <TMPL_VAR fullname>
         </TMPL_WITH>

       "fullname" will call the fullname method of your Your::Class object.

       It's recommended to just use the default . value for methods and dereferencing.

       I might stop supporting that you can set the values for method calls by setting an option.
       Ideally I would like to have that behaviour changed only by inheriting.

   RUNNING PERL WITH TMPL_PERL
       Yes, templating systems are for separating code and templates. But as it turned out to be
       implemented much easier than expressions i decided to implement it. But expressions are
       also available with the option "use_expressions".

       Note: If you have templates that can be edited by untrustworthy persons then you don't
       want them to include perl code.

       So, how do you use the perl-tag? First, you have to set the option "use_perl" to 1 when
       creating a template object.

       Important note: don't use "print" in the included code. Usually the template code is
       concatenated and returned to your perl script.  To 'print' something out use

           __OUT__ 2**3;

       This will be turned into something like

           $OUT .= 2**3;
           # or
           print $fh 2**3;

       Important note 2: HTC does not parse Perl. if you use the classic tag-delimiters like
       this:

           <tmpl_perl if (__CURRENT__->count > 42) { >

       this will not work as it might seem. Use other delimiters instead:

           <%perl if (__CURRENT__->count > 42) { %>

       Example:

           <tmpl_loop list>
           <tmpl_perl unless (__INDEX__ % 3) { >
             </tr><tr>
           <tmpl_perl } >
           </tmpl_loop list>

           # takes the current position of the parameter
           # hash, key 'foo' and multiplies it with 3
           <%perl __OUT__ __CURRENT__->{foo} * 3; %>

       List of special keywords inside a perl-tag:

       __OUT__
           Is turned into "$OUT .=" or "print $fh"

       __HTC__
           Is turned into the variable containing the current template object.

       __CURRENT__
           Turned into the variable containing the current position in the parameter hash.

       __ROOT__
           Turned into the variable containig the parameter hash.

       __INDEX__
           Turned into the current index of a loop (starting with 0).

   INHERITANCE
       It's possible since version 0.69 to inherit from HTML::Template::Compiled.  It's just not
       documented, and internal method names might change in the near future. I'll try to fix the
       API and document which methods you can inherit.

       METHODS TO INHERIT

       method_call
           Default is "sub method_call { '.' }"

       deref
           Default is "sub deref { '.' }"

       formatter_path
           Deprecated, see HTML::Template::Compiled::Formatter please.

       compile_early
           Define if every included file should be checked and parsed at compile time of the
           including template or later when it is really used.

           Default is "sub compile_early { 1 }"

       parser_class
           Default is "sub parser_class { 'HTML::Template::Compiled::Parser' }"

           You can write your own parser class (which must inherit from
           HTML::Template::Compiled::Parser) and use this.

           HTML::Template::Compiled::Lazy uses this.

   DEBUGGING
       For printing out the contents of all the parameters you can do:

         <TMPL_LOOP ALBUMS>
         Dump: <TMPL_VAR _ ESCAPE=DUMP|HTML>
         </TMPL_LOOP>

       The special name "_" gives you the current parameter and "ESCAPE=DUMP" will by default
       generate a Data::Dumper output of the current variable, in this case it will dump out the
       contents of every album in a loop. To correctly display that in html "|HTML" will escape
       html entities.

   TMPL_WITH
       If you have a deep leveled hash you might not want to always write
       THE.FULL.PATH.TO.YOUR.VAR. Jump to your desired level once and then you need only one
       level. Compare:

         <TMPL_WITH DEEP.PATH.TO.HASH>
         <TMPL_VAR NAME>: <TMPL_VAR AGE>
         </TMPL_WITH>

         <TMPL_VAR DEEP.PATH.TO.HASH.NAME>: <TMPL_VAR DEEP.PATH.TO.HASH.AGE>

       Inside TMPL_WITH you can't reference parent nodes unless you're using global_vars.

   TMPL_LOOP
       The special name "_" gives you the current parameter. In loops you can use it like this:

        <tmpl_loop foo>
         Current item: <tmpl_var _ >
        </tmpl_loop>

       Also you can give the current item an alias. See "ALIAS".

       The LOOP tag allows you to define a JOIN attribute:

        <tmpl_loop favourite_colors join=", ">
         <tmpl_var _ >
        </tmpl_loop>

       This will output something like "blue, pink, yellow".  This is easier than doing:

        <tmpl_loop favourite_colors>
        <tmpl_unless __first__>, </tmpl_unless>
         <tmpl_var _ >
        </tmpl_loop>

       The "LOOP", "WHILE" and "EACH" tags allow you to define a BREAK attribute:

        <tmpl_loop bingo break="3"> <tmpl_var _ ><if __break__>\n</if></tmpl_loop>

           $htc->param(bingo => [qw(X 0 _ _ X 0 _ _ X)]);

       outputs

           X 0 _
           _ X 0
           _ _ X

       So specifying BREAK=3 sets __break__ to 1 every 3rd loop iteration.

       TMPL_LOOP expects an array reference, also if it is a method call. If you want to iterate
       with TMPL_LOOP over a list from a method call, set the attribute "context=list":

           <tmpl_loop object.list_method context=list>
               <tmpl_var _ >
           </tmpl_loop>

   TMPL_WHILE
       Useful for iterating, for example over database resultsets.  The directive

         <tmpl_while resultset.fetchrow>
           <tmpl_var _.0>
         </tmpl_while>

       will work like:
         while (my $row = $resultset->fetchrow) {
           print $row->[0];
         }

       So the special variable name _ is set to the current item returned by the iterator.

       You also can use "ALIAS" here.

   TMPL_EACH
       Iterating over a hash. Internally it is not implemented as an each, so you can also sort
       the output:

           Sorted alphanumerically by default (since 0.93):
               <tmpl_each letters >
                   <tmpl_var __key__ >:<tmpl_var __value__>
               </tmpl_each letters >
           Sorted numerically:
               <tmpl_each numbers sort=num >
                   <tmpl_var __key__ >:<tmpl_var __value__>
               </tmpl_each numbers >
           Not sorted:
               <tmpl_each numbers sort=0 >
                   <tmpl_var __key__ >:<tmpl_var __value__>
               </tmpl_each numbers >
           Sorted alphanumerically:
               <tmpl_each letters sort=alpha >
                   <tmpl_var __key__ >:<tmpl_var __value__>
               </tmpl_each letters >

       You have to set the option "loop_context_vars" to true to use the special vars "__key__"
       and "__value__".

       If you want to iterate over a hash instead of a hashref (some methods might return plain
       hashes instead of references and TMPL_EACH expects a ref), then you can set
       "context=list":

           <tmpl_each object.hash_method context=list>
           <tmpl_var __key__ >
           </tmpl_each>

       Since 1.000_001 you can also define by which variable you want to sort.  If you have a
       hash with hashes as values:

           $htc->param(
               letters => {
                   1 => { letter =>'b' },
                   2 => { letter =>'a' },
                   3 => { letter =>'c' },
               },
           );
           <%each letters sort=alpha sortby="letter" %>
           <%set_var val value=__value__ %>
           <%= __key__ %> = <%= $val.letter %>
           <%/each%>

   SET_VAR
       Since 0.96_002

       Sets a local variable to the value given in "value" or "expr"

           <tmpl_set foo expr=23>
           <tmpl_set name=bar expr=23>
           <tmpl_set boo value=var.boo>
           <tmpl_set oof expr="21*2">
           <tmpl_var $foo>
           <tmpl_var $bar>
           ...

       "value=.." behaves like a variable name from the parameter stash.  The variable name to
       set must match /[0-9a-z_]+/i

       You can refer to an alias via $alias or simply "alias". Note that the latter syntax is not
       recommeded any more since it can conflict with parameters from the stash.

       If you want to use aliases in includes, you need to use the $alias syntax.

   USE_VARS
       deprecated. Was added in 0.96_004 to make it possible to use aliases set with "alias=..."
       or "SET_VAR" in includes. Now you should rather use the <$alias> syntax.

       The following explanation is just there for history and will be removed some time in the
       future. For now it still works.

       Necessary if you want vars like SET_VAR and loop aliases from outside in includes.  Before
       the first use in the include, add:

           <tmpl_use_vars foo,bar,boo >

       so that the compiler recognizes them as user defined vars and not parameters from the
       stash.  This statement is valid until the end of the template so you cannot "overwrite"
       parameters of the stash locally.

   WRAPPER
       Since 0.97_005. Experimental. Please test.

       Needs option "loop_context_vars".

       Works similar to WRAPPER in Template-Toolkit.

       Is similar to TMPL_INCLUDE, just that the included wrapper is wrapped around the content.
       It can be used to avoid including head and foot separately.

           <tmpl_wrapper wrapper.html >
           content: some var: <tmpl_var foo >
           </tmpl_wrapper>

       In wrapper.html the special loop context var "__wrapper__" is used for the included
       content:

           wrapper.html:
           <some><layout>
           <tmpl_var __wrapped__ >
           </layout></some>

       Important notes:

       If you are using "out_fh" to print directly to a filehandle instead of returning to a
       string, this feature might not be useful, since it is appending the content inside of the
       wrapper to a string and prints it when it comes to the end of the wrapper tag.  So if you
       are using "out_fh" to avoid generating long strings in memory, you should rather use
       TMPL_INCLUDE instead.

       Also you need perl 5.8 or higher to use it in combination with out_fh.

   TMPL_COMMENT
       For debugging purposes you can temporarily comment out regions:

         Wanted: <tmpl_var wanted>
           <tmpl_comment outer>
           this won't be printed
             <tmpl_comment inner>
               <tmpl_var unwanted>
             </tmpl_comment inner>
             <tmpl_var unwanted>
         </tmpl_comment outer>

         $htc->param(unwanted => "no thanks", wanted => "we want this");

       The output is (whitespaces stripped):

         Wanted: we want this

       HTC will ignore anything between COMMENT directives.  This is useful for debugging, and
       also for documentation inside the template which should not be outputted.

   TMPL_NOPARSE
       Anything between

         <tmpl_noparse>...</tmpl_noparse>

       will not be recognized as template directives. Same syntax as TMPL_COMMENT.  It will
       output the content, though.

   TMPL_VERBATIM
       Anything between

         <tmpl_verbatim>...</tmpl_verbatim>

       will not be recognized as template directives. Same syntax as "TMPL_NOPARSE", but it will
       be HTML-Escaped. This can be useful for debugging.

   TMPL_SWITCH
       The SWITCH directive has the same syntax as VAR, IF etc.  The CASE directive takes a
       simple string or a comma separated list of strings.  Yes, without quotes. This will
       probably change! I just don't know yet how it should look like. Suggestions?

       With that directive you can do simple string comparisons.

        <tmpl_switch language>(or <tmpl_switch name=language>)
         <tmpl_case de>echt cool
         <tmpl_case en>very cool
         <tmpl_case es>superculo
         <tmpl_case fr,se>don't speak french or swedish
         <tmpl_case default>sorry, no translation for cool in language <%=language%> available
         <tmpl_case>(same as default)
        </tmpl_switch>

       It's also possible to specify the default with a list of other strings:

        <tmpl_case fr,default>

       Note that the default case should always be the last statement before the closing switch.

   OPTIONS
       As you can cache the generated perl code in files, some of the options are fixed; that
       means for example if you set the option case_sensitive to 0 and the next time you call the
       same template with case_sensitive 1 then this will be ignored. The options below will be
       marked as (fixed).

       path
           Path to template files

       search_path_on_include
           Search the list of paths specified with "path" when including a template.  Default is
           0

           See "DIFFERENT FEATURES" for the additional possible value 2.

       file_cache
           Set to 1 if you want to use file caching and specify the path with file_cache_dir.

       file_cache_dir
           Path to caching directory (you have to create it before)

       cache_dir
           Replaced by file_cache_dir like in HTML::Template. Will be deprecated in future
           versions.

       cache
           Is 1 by default. If set to 0, no memory cacheing is done. Only recommendable if you
           have a dynamic template content (with scalarref, arrayre for example).

       expire_time
           Recheck template files on disk after "expire_time" seconds. See "CACHING"

       filename
           Template to parse

       scalarref
           Reference to a scalar with your template content. It's possible to cache scalarrefs,
           too, if you have Digest::MD5 installed. Note that your cache directory might get
           filled with files from earlier versions. Clean the cache regularly.

           Don't cache scalarrefs if you have dynamic strings. Your memory might get filled up
           fast!  Use the option

             cache => 0

           to disable memory caching.

       arrayref
           Reference to array containing lines of the template content (newlines have to be
           included)

       filehandle
           Filehandle which contains the template content. Note that HTC will not cache templates
           created like this.

       loop_context_vars (fixed)
           Vars like "__first__", "__last__", "__inner__", "__odd__", "__counter__", "__index__",
           "__outer__", "__even__"

           The variable "__index__" works just like "__counter__", only that it starts at 0
           instead of 1.

       global_vars (fixed)
           If set to 1, every outer variable can be accessed from anywhere in the enclosing
           scope.

           Default is 0.

           Note that I don't recommend using global_vars. For referring to parameters up in the
           stash you can use aliases via "alias=..." or "SET_VAR".  See "ALIAS" and "SET_VAR".

           If yoy still would like to be able to navigate up the parameter stash, you have the
           following option:

           If set to 2, you don't have global vars, but have the possibility to go up the stack
           one level. Example:

            <tmpl_var ...key>

           This will get you up 2 levels (remember: one dot means root in HTC) and access the
           'key' element.

           If set to 3 ("3 == 1|2") you have both, global vars and explicitly going up the stack.

           So setting global_vars to 2 can save you from global vars but still allows you to
           browse through the stack.

       default_escape
             my $htc = HTML::Template::Compiled->new(
               ...
               default_escape => 'HTML', # or URL
             );

           Now everything will be escaped for HTML unless you explicitly specify "ESCAPE=0" (no
           escaping) or "ESCAPE=URL".

       strict (since 0.97_001)
           Default: 1

           If set to 0 unknown tags will be ignored and output verbatim:

               <TMPL_FOOBAR anything ... <TMPL_VAR valid>

       line_info (fixed) (since 1.000_004)
           Default: 0

             my $htc = HTML::Template::Compiled->new(
                 ...
                 line_info => 1, # default 0
             );

           If any runtime errors occur, line information will output the template filename and
           line (instead of "eval" and the generated perl code line)

       warnings (fixed) (since 1.000_004)
           Default: 0

           If set to 1, runtime warnings (like use of uninitialized value) will be output to
           stderr.

           If set to 'fatal', any runtime warning will cause the script to die.

       no_includes (since 0.92)
           Default is 0. If set to 1, the tags INCLUDE, INCLUDE_VAR and INCLUDE_STRING will cause
           a template syntax error when creating. This can be useful when opening untrusted
           templates, otherwise any file in the filesystem could be opened.

       debug_file (fixed) (since 0.91_001)
           Additionally to the context_vars __filename__ and __filenameshort__ you can enable
           filename debugging globally.

           If the option is set to 'start', at the start of every template will be added:
               <!-- start templates/path/filename.html -->

           If set to 'end', at the end will be added:
               <!-- end templates/path/filename.html -->

           If set to 'start,end', both coments will be added.

           If set to 'start,short', 'end,short' or 'start,end,short' the path to the templates
           will be stripped:
               <!-- start path/filename.html -->
               <!-- end path/filename.html -->

       objects (fixed) (since 0.91_001)
           if set to true, you can use method calls like
               <%= object.method %>

           Default is 'strict' (true).  If set to 'strict', the method will be called if we have
           an object, otherwise it's treated as a hash lookup. If the method doesn't exist, it
           dies.  If set to 'nostrict', the method will be called only if the object 'can' do the
           method, otherwise it will return undef (this will need Scalar::Util).  If set to 0, no
           method calls are allowed.

       deref (fixed)
           Deprecated. Please inherit and overwrite method 'deref'. See "INHERITANCE"

           Define the string you want to use for dereferencing, default is "." at the moment:

            <TMPL_VAR hash.key>

       method_call (fixed)
           Deprecated. Please inherit and overwrite method 'method_call'. See "INHERITANCE"

           Define the string you want to use for method calls, default is . at the moment:

            <TMPL_VAR object.method>

           Don't use ->, though, like you could in earlier version. Var names can contain:
           Numbers, letters, '.', '/', '+', '-' and '_', just like HTML::Template. Note that if
           your var names contain dots, though, they will be treated as hash dereferences. If you
           want literal dots, use HTML::Template::Compiled::Classic instead.

       default_path (fixed)
           Deprecated, see HTML::Template::Compiled::Formatter please.

             my $htc = HTML::Template::Compiled->new(
               ...
               default_path
                    # default is PATH_DEREF
                 => HTML::Template::Compiled::Utils::PATH_FORMATTER,
             );

           Is needed if you have an unqualified tmpl_var that should be resolved as a call to
           your formatter, for example. Otherwise you have to call it fully qualified. If your
           formatter_path is '/', you'd say tmpl_var "_/method".  With the option default_path
           you can make that the default, so you don't need the "_/": "tmpl_var method". If you
           don't use formatters, don't care about this option.

       line_numbers
           NOTE: This option does not exist any more; line numbers will alway be reported.

           For debugging: prints the line number of the wrong tag, e.g. if you have a /TMPL_IF
           that does not have an opening tag.

       case_sensitive (fixed)
           default is 1, set it to 0 to use this feature like in HTML::Template. Note that this
           can slow down your program a lot (50%).

       dumper
           This option is deprecated as of version 0.76. You must now use a plugin instead, like
           HTML::Template::Compiled::Plugin::DHTML, for examle.

             my $t = HTML::Template::Compiled->new(
               ...
               dumper = sub { my_cool_dumper($_[0]) },
             );

             <TMPL_VAR var ESCAPE=DUMP>

           This will call "my_cool_dumper()" on "var".

           Alternatively you can use the DHTML plugin which is using "Data::TreeDumper" and
           "Data::TreeDumper::Renderer::DHTML". You'll get a  dumper like output which you can
           collapse and expand, for example. See Data::TreeDumper and
           Data::TreeDumper::Renderer::DHTML for more information.  Example:

             my $t = HTML::Template::Compiled->new(
               ...
               dumper = 'DHTML',
             );

           For an example see "examples/dhtml.html".

       out_fh (fixed)
             my $t = HTML::Template::Compiled->new(
               ...
               out_fh => 1,
             );
             ...
             $t->output($fh); # or output(\*STDOUT) or even output()

           This option is fixed, so if you create a template with "out_fh", every output of this
           template will print to a specified (or default "STDOUT") filehandle.

       filter
           Filter template code before parsing.

             my $t = HTML::Template::Compiled->new(
               ...
               filter => sub { myfilter( ${$_[0]} ) },
               # or
               filter => [ {
                   sub => sub { myfilter( ${$_[0]} ) },
                   format => 'scalar', # or array
                 },
                 ...
               ],
             );

       tagstyle (fixed)
           Specify which styles you want to use. This option takes an arrayref with strings of
           named tagstyles or your own regexes.

           At the moment there are the following named tagstyles builtin:

               # classic (active by default)
               <TMPL_IF foo><tmpl_var bar></TMPL_IF>

               # comment (active by default)
               <!-- TMPL_IF foo --><!-- TMPL_VAR bar --><!-- /TMPL_IF -->

               # asp (active by default)
               <%if foo%><%VAR bar%><%/if%>

               # php (not active by default)
               <?if foo?><?var bar?><?/if foo?>

               # tt (not active by default)
               [%if foo%][%var bar%][%/if foo%]

           You deactive a style by saying -stylename. You activate by saying +stylename.

           Define your own tagstyle by specifyin regexes. For example you want to use {"{if
           foo}}{{var bar}}{{/if foo}}", then your definition should be:

               [
                   qr({{), # start of opening tag
                   qr(}}), # end of opening tag
                   qr({{/), # start of closing tag
                   qr(}}), # end of closing tag
               ]

           NOTE: do not specify capturing parentheses in you regexes. If you need parentheses,
           use "(?:foo|bar)" instead of "(foo|bar)".

           Say you want to deactivate asp-style, comment-style, activate php- and tt-style and
           your own "{{}} " style, then say:

               my $htc = HTML::Template::Compiled->new(
                   ...
                   tagstyle => [
                       qw(-asp -comment +php +tt),
                       [ qr({{), qr(}}), qr({{/), qr(}})],
                   ],
               );

       use_expressions (since 0.91_003)
           Set to 1 if you want to use expressions. The basic expressions work more or less like
           in HTML::Template::Expr - I took the parsing code from it and used it with some minor
           changes - thanks to Sam Tregar.

               <%if expr="some.var > 3" %>It's grater than 3<%/if %>

           But with expressions you can also use more complex navigation through the template
           stash:

           You can use object methods with parameters. While a normal method call can only be
           called without parameters, like

               <%= object.name %>

           with expressions you can give it parameters:

               <%= expr="object.create_link('navi')" %>

           Inside function and method calls, hash keys you also can use template vars (array
           indices and hash keys since 0.96_003).

               <%= expr=".path.to.hash{var}" %>
               <%= expr=".path.to.hash{.another.var[123]}{'literal key'}" %>

           It is only minimally tested yet, so use with care and please report any bugs you find.

           A useful example: Output a number of items with their prices formatted.

               my $nf = Number::Format->new(...);
               my $htc = HTML::Template::Compiled->new(
                   filename => 'items.html',
                   use_expressions => 1,
               );
               $htc->param(
                   items => [
                       { size =>  50 * 1024 * 1024 * 1024, price => 49.95 },
                       { size => 250 * 1024 * 1024 * 1024, price => 110.99 },
                   ],
                   nf => $nf,
               );

           items.html:

               <%loop .items %>
               Size: <%= expr=".nf.format_bytes(size)" %>
               Price: <%= expr=".nf.format_price(price)" %>
               <%/loop %>

           Output:
               Size: 50G
               Price: 49,95 EUR

               Size: 250G
               Price: 110,99 EUR

       formatter
           Deprecated, see HTML::Template::Compiled::Formatter please.

           With formatter you can specify how an object should be rendered. This is useful if you
           don't want object methods to be called, but only a given subset of methods.

             my $htc = HTML::Template::Compiled->new(
             ...
             formatter => {
               'Your::Class' => {
                 fullname => sub {
                   $_[0]->first . ' ' . $_[0]->last
                 },
                 first => Your::Class->can('first'),
                 last => Your::Class->can('last'),
                 },
               },
             );
             # $obj is a Your::Class object
             $htc->param(obj => $obj);
             # Template:
             # Fullname: <tmpl_var obj/fullname>

       formatter_path (fixed)
           Deprecated, see HTML::Template::Compiled::Formatter please.

       debug
           If set to 1 you will get the generated perl code on standard error

       use_query
           Set it to 1 if you plan to use the query() method. Default is 0.

           Explanation: If you want to use query() to collect information on the template HTC has
           to do extra-work while compiling and uses extra-memory, so you can choose to save HTC
           work by setting use_query to 0 (default) or letting HTC do the extra work by setting
           it to 1. If you would like 1 to be the default, write me. If enough people write me,
           I'll think abou it =)

       use_perl
           Set to 1 if you want to use the perl-tag. See "TMPL_PERL". Default is 0.

       cache_debug
           Default: 0

           You can debug hits and misses for file cache and memory cache:

               # debug all cache
               my $htc = HTML::Template::Compiled->new(
                   cache_debug => 1,
                   ...
               );
               # only debug misses
               my $htc = HTML::Template::Compiled->new(
                   cache_debug => [qw/ file_miss mem_miss /],
                   ...
               );

           Possible values when passing an array ref: file_miss file_hit mem_miss mem_hit

           Output looks similar to HTML::Template cache_debug and will be output to STDERR via
           warn().

   METHODS
       clear_cache ([DIR])
           Class method. It will clear the memory cache either of a specified cache directory:

             HTML::Template::Compiled->clear_cache($cache_dir);

           or all memory caches:

             HTML::Template::Compiled->clear_cache();

       clear_filecache
           Class- or object-method. Removes all generated perl files from a given directory.

             # clear a directory
             HTML::Template::Compiled->clear_filecache('cache_directory');
             # clear this template's cache directory (and not one template file only!)
             $htc->clear_filecache();

       param
           Works like in HTML::Template.

       query
           Works like in HTML::Template. But it is not activated by default. If you want to use
           it, specify the use_query option.

       preload
           Class method. Will preload all template files from a given cachedir into memory.
           Should be done, for example in a mod_perl environment, at server startup, so all
           templates go into "shared memory"

             HTML::Template::Compiled->preload($cache_dir);

           If you don't do preloading in mod_perl, memory usage might go up if you have a lot of
           templates.

           Note: the directory is *not* the template directory. It should be the directory which
           you give as the file_cache_dir option.

       precompile
           Class method. It will precompile a list of template files into the specified cache
           directory. See "PRECOMPILE".

       clear_params
           Empty all parameters.

       debug_code (since 0.91_003)
           If you get an error from the generated template, you might want to debug the executed
           code. You can now call "debug_code" to get the compiled code and the line the error
           occurred. Note that the reported line might not be the exact line where the error
           occurred, also look around the line.  The template filename reported does currently
           only report the main template, not the name of an included template. I'll try to fix
           that.

               local $HTML::Template::Compiled::DEBUG = 1;
               my $htc = HTML::Template::Compiled->new(
                   filename => 'some_file_with_runtime_error.html',
               );
               eval {
                   print $htc->output;
               };
               if ($@) {
                   # reports as text
                   my $msg = $htc->debug_code;
                   # reports as a html table
                   my $msg_html = $htc->debug_code('html');
               }

       get_plugin
               my $plugin = $htc->get_plugin('Name::of::plugin');

           Returns the plugin object of that classname. If the plugin is only a string (the
           classname itself), it returns this string, so this method is only useful for plugin
           objects.

       var2expression
           Useful for plugins. Parses a template var ("name="foo.bar.baz"" and returns the perl
           expression for the compiler.

EXPORT

       None.

CACHING

       You create a template almost like in HTML::Template:

         my $t = HTML::Template::Compiled->new(
           path                => 'templates',
           loop_context_vars   => 1,
           filename            => 'test.html',
           # for testing without cache comment out
           file_cache          => 1,
           file_cache_dir      => "cache",
         );

       The next time you start your application and create a new template, HTC will read all
       generated perl files, and a call to the constructor like above won't parse the template,
       but just use the loaded code. If your template file has changed, though, then it will be
       parsed again.

       You can set the expire time of a template by passing the option

           expire_time => $seconds

       Note that

           HTML::Template::Compiled->ExpireTime($seconds);
           C<$HTML::Template::Compiled::NEW_CHECK>

       are deprecated since they change a global variable which is then visible in the whole
       process, so in persistent environments other apps might be affected.

       So an expire time of 600 seconds (default) will check after 10 minutes if the tmpl file
       was modified. Set it to a very high value will then ignore any changes, until you delete
       the generated code.  For development you should set it to 0, for a pre-production server
       you can set it to 60 seconds, for example. It can make quite a difference.

PLUGINS

       At the moment you can use and write plugins for the "ESCAPE" attribute. See
       HTML::Template::Compiled::Plugin::XMLEscape for an example how to use it; and have a look
       at the source code if you want to know how to write a plugin yourself.

       Using Plugins:

           my $htc = HTML::Template::Compiled->new(
               ...
               plugin => ['HTML::Template::Compiled::Foo::Bar'],
               # oor shorter:
               plugin => ['::Foo::Bar'],
           );

LAZY LOADING

       Let's say you're in a CGI environment and have a lot of includes in your template, but
       only few of them are actually used. HTML::Template::Compiled will (as HTML::Template does)
       parse all of your includes at once.  Just like the "use" function does in perl. To get a
       behaviour like require, use HTML::Template::Compiled::Lazy.

TODO

       associate, methods with simple parameters, expressions, pluggable, ...

IMPLEMENTATION

       HTC generates a perl subroutine out of every template. Each included template is a
       subroutine for itself. You can look at the generated code by activating file caching and
       looking into the cache directory. When you call "output()", the subroutine is called. The
       subroutine either creates a string and adds each template text or the results of the tags
       to the string, or it prints it directly to a filehandle. Because of the implementation you
       have to know at creation time of the module if you want to get a string back or if you
       want to print to a filehandle.

SECURITY

       HTML::Template::Compiled uses basically the same file caching model as, for example,
       Template- Toolkit does: The compiled Perl code is written to disk and later reread via
       "do" or by reading the file and "eval" the content.

       If you are sharing a read/write environment with untrusted users (for example on a machine
       with a webserver, like many webhosters offer, and all scripts are running as the same
       httpd user), realize that there is possibility of modifying the Perl code that is cached
       and then executed. The best solution is to not be in such an environment!

       In this case it is the safest option to generate your compiled templates on a local
       machine and just put the compiled templates onto the server, with no write access for the
       http server.  Set the "expire_time" option to a high value so that HTC never attempts to
       check the template timestamp to force a regenerating of the code.

       If you are alone on the machine, but you are running under taint mode (see perlsec) then
       you have to explicitly set the $UNTAINT variable to 1. HTC will then untaint the code for
       you and treat it as if it were safe (it hopefully is =).

PRECOMPILE

       I think there is no way to provide an easy function for precompiling, because every
       template can have different options.  If you have all your templates with the same
       options, then you can use the precompile class method.  It works like this:

         HTML::Template::Compiled->precompile(
           # usual options like path, default_escape, global_vars, file_cache_dir, ...
           filenames => [ list of template-filenames ],
         );

       This will then pre-compile all templates into file_cache_dir. Now you would just put this
       directory onto the server, and it doesn't need any write-permissions, as it will be never
       changed (until you update it because templates have changed).

BENCHMARKS

       The options "case_sensitive", "loop_context_vars" and "global_vars" can have the biggest
       influence on speed.

       Setting case_sensitive to 1, loop_context_vars to 0 and global_vars to 0 saves time.

       On the other hand, compared to HTML::Template, you have a large speed gain under mod_perl
       if you use case_sensitive = 1, loop_context_vars = 0, With CGI HTC is slower.

       See the "examples/bench.pl" contained in this distribution.

       Here are some examples from the benchmark script. I'm showing only Template::AutoFilter,
       Template::HTML, HTML::Template and HTC. These four modules allow to set automatic HTML
       escaping ('filter') for all variables.

        loop_context_vars 1
        global_vars 0
        case_sensitive 1
        default_escape HTML (respectively Template::AutoFilter and Template::HTML)

        ht: HTML::Template 2.10
        htc: HTML::Template::Compiled 0.95
        ttaf: Template::AutoFilter 0.112350 with Template 2.22
        tth: Template::HTML 0.02 with Template 2.22

       First test is with the test.(htc|tt) from the examples directory, about 900 bytes.

       Test without file cache and without memory cache.

         process_tth:  1 wallclock secs ( 1.05 usr +  0.00 sys =  1.05 CPU) @ 609.52/s (n=640)

       Now I'm using a template with about 18Kb by multiplying the example template 20 times. You
       can see that everything is running slower but some run more slower than others.

       Test without file cache and without memory cache.

                     all_ht:  8 wallclock secs ( 7.57 usr +  0.04 sys =  7.61 CPU) @ 13.14/s (n=100)
                    all_htc: 32 wallclock secs (32.08 usr +  0.06 sys = 32.14 CPU) @  3.11/s (n=100)
        all_ttaf_new_object: 36 wallclock secs (36.21 usr +  0.04 sys = 36.25 CPU) @  2.76/s (n=100)
         all_tth_new_object: 29 wallclock secs (28.92 usr +  0.05 sys = 28.97 CPU) @  3.45/s (n=100)

       With file cache:

                     all_ht:  8 wallclock secs ( 7.22 usr +  0.00 sys =  7.22 CPU) @ 13.85/s (n=100)
                    all_htc:  5 wallclock secs ( 5.32 usr +  0.00 sys =  5.32 CPU) @ 18.80/s (n=100)
        all_ttaf_new_object:  8 wallclock secs ( 7.59 usr +  0.15 sys =  7.74 CPU) @ 12.92/s (n=100)
         all_tth_new_object:  9 wallclock secs ( 8.74 usr +  0.19 sys =  8.93 CPU) @ 11.20/s (n=100)

       With memory cache:

              all_ht:  1 wallclock secs ( 1.04 usr +  0.01 sys =  1.05 CPU) @ 15.24/s (n=16)
             all_htc:  1 wallclock secs ( 1.12 usr +  0.00 sys =  1.12 CPU) @ 272.32/s (n=305)
        process_ttaf:  1 wallclock secs ( 1.07 usr +  0.00 sys =  1.07 CPU) @ 39.25/s (n=42)
         process_tth:  1 wallclock secs ( 1.05 usr +  0.00 sys =  1.05 CPU) @ 34.29/s (n=36)

       So the performance difference highly depends on the size of the template and on the
       various options.  You can see that using the 900byte template HTC is slower with file
       cache than HTML::Template, but with the 18Kb template it's faster.

EXAMPLES

       See "objects.html" in examples (and "examples/objects.pl") for an example how to feed
       objects to HTC.

BUGS

       Probably many bugs I don't know yet =)

       Use the bugtracking system to report a bug:

Why another Template System?

       You might ask why I implement yet another templating system. There are so many to choose
       from. Well, there are several reasons.

       I like the syntax of HTML::Template *because* it is very restricted.  It's also easy to
       use (template syntax and API).  However, there are some things I miss I try to implement
       here.

       I think while HTML::Template is quite good, the implementation can be made more efficient
       (and still pure Perl). That's what I'm trying to achieve.

       I use it in my web applications, so I first write it for myself =) If I can efficiently
       use it, it was worth it.
