    to Perl code

VERSION
    $VERSION = "1.000_002"

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($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.

  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 objcets
        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 expire_time 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>

    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 specifying for 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(

    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)

    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.

                  all_ht:  1 wallclock secs ( 0.40 usr +  0.00 sys =  0.40 CPU) @ 250.00/s (n=100)
                 all_htc:  1 wallclock secs ( 1.74 usr +  0.01 sys =  1.75 CPU) @ 57.14/s (n=100)
     all_ttaf_new_object:  1 wallclock secs ( 1.69 usr +  0.01 sys =  1.70 CPU) @ 58.82/s (n=100)
      all_tth_new_object:  1 wallclock secs ( 1.44 usr +  0.00 sys =  1.44 CPU) @ 69.44/s (n=100)

    With file cache:

                  all_ht:  1 wallclock secs ( 1.03 usr +  0.01 sys =  1.04 CPU) @ 379.81/s (n=395)
                 all_htc:  1 wallclock secs ( 1.07 usr +  0.00 sys =  1.07 CPU) @ 260.75/s (n=279)
     all_ttaf_new_object:  1 wallclock secs ( 1.07 usr +  0.04 sys =  1.11 CPU) @ 251.35/s (n=279)
      all_tth_new_object:  1 wallclock secs ( 1.01 usr +  0.04 sys =  1.05 CPU) @ 227.62/s (n=239)

    With memory cache:

           all_ht:  1 wallclock secs ( 1.04 usr +  0.00 sys =  1.04 CPU) @ 461.54/s (n=480)
          all_htc:  1 wallclock secs ( 1.05 usr +  0.01 sys =  1.06 CPU) @ 3168.87/s (n=3359)
     process_ttaf:  1 wallclock secs ( 1.04 usr +  0.00 sys =  1.04 CPU) @ 679.81/s (n=707)
      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:
    http://rt.cpan.org/NoAuth/Bugs.html?Dist=HTML-Template-Compiled

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.
