You may modify your copy or copies of the Program or any portion of +it, and copy and distribute such modifications under the terms of Paragraph +1 above, provided that you also do the following: + + a) cause the modified files to carry prominent notices stating that + you changed the files and the date of any change; and + + b) cause the whole of any work that you distribute or publish, that + in whole or in part contains the Program or any part thereof, either + with or without modifications, to be licensed at no charge to all + third parties under the terms of this General Public License (except + that you may choose to grant warranty protection to some or all + third parties, at your option). + + c) If the modified program normally reads commands interactively when + run, you must cause it, when started running for such interactive use + in the simplest and most usual way, to print or display an + announcement including an appropriate copyright notice and a notice + that there is no warranty (or else, saying that you provide a + warranty) and that users may redistribute the program under these + conditions, and telling the user how to view a copy of this General + Public License. + + d) You may charge a fee for the physical act of transferring a + copy, and you may at your option offer warranty protection in + exchange for a fee. + +Mere aggregation of another independent work with the Program (or its +derivative) on a volume of a storage or distribution medium does not bring +the other work under the scope of these terms. + + 3. You may copy and distribute the Program (or a portion or derivative of +it, under Paragraph 2) in object code or executable form under the terms of +Paragraphs 1 and 2 above provided that you also do one of the following: + + a) accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Paragraphs 1 and 2 above; or, + + b) accompany it with a written offer, valid for at least three + years, to give any third party free (except for a nominal charge + for the cost of distribution) a complete machine-readable copy of the + corresponding source code, to be distributed under the terms of + Paragraphs 1 and 2 above; or, + + c) accompany it with the information you received as to where the + corresponding source code may be obtained. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form alone.) + +Source code for a work means the preferred form of the work for making +modifications to it. For an executable file, complete source code means +all the source code for all modules it contains; but, as a special +exception, it need not include source code for modules which are standard +libraries that accompany the operating system on which the executable +file runs, or for standard header files or definitions files that +accompany that operating system. + + 4. You may not copy, modify, sublicense, distribute or transfer the +Program except as expressly provided under this General Public License. +Any attempt otherwise to copy, modify, sublicense, distribute or transfer +the Program is void, and will automatically terminate your rights to use +the Program under this License. However, parties who have received +copies, or rights to use copies, from you under this General Public +License will not have their licenses terminated so long as such parties +remain in full compliance. + + 5. By copying, distributing or modifying the Program (or any work based +on the Program) you indicate your acceptance of this license to do so, +and all its terms and conditions. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the original +licensor to copy, distribute or modify the Program subject to these +terms and conditions. You may not impose any further restrictions on the +recipients' exercise of the rights granted herein. + + 7. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of the license which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +the license, you may choose any version ever published by the Free Software +Foundation. + + 8. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to humanity, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest to +attach them to the start of each source file to most effectively convey +the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 1, or (at your option) + any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19xx name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the +appropriate parts of the General Public License. Of course, the +commands you use may be called something other than `show w' and `show +c'; they could even be mouse-clicks or menu items--whatever suits your +program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

(You will + not be required to justify it to the Copyright Holder, but only to the + computing community at large as a market that must bear the fee.) + - "Freely Available" means that no fee is charged for the item itself, though + there may be fees involved in handling the item. It also means that + recipients of the item may redistribute it under the same conditions they + received it. + +1. You may make and give away verbatim copies of the source form of the +Standard Version of this Package without restriction, provided that you +duplicate all of the original copyright notices and associated disclaimers. + +2. You may apply bug fixes, portability fixes and other modifications derived +from the Public Domain or from the Copyright Holder. A Package modified in such +a way shall still be considered the Standard Version. + +3. You may otherwise modify your copy of this Package in any way, provided that +you insert a prominent notice in each changed file stating how and when you +changed that file, and provided that you do at least ONE of the following: + + a) place your modifications in the Public Domain or otherwise make them + Freely Available, such as by posting said modifications to Usenet or an + equivalent medium, or placing the modifications on a major archive site + such as ftp.uu.net, or by allowing the Copyright Holder to include your + modifications in the Standard Version of the Package. + + b) use the modified Package only within your corporation or organization. + + c) rename any non-standard executables so the names do not conflict with + standard executables, which must also be provided, and provide a separate + manual page for each non-standard executable that clearly documents how it + differs from the Standard Version. + + d) make other distribution arrangements with the Copyright Holder. + +4. You may distribute the programs of this Package in object code or executable +form, provided that you do at least ONE of the following: + + a) distribute a Standard Version of the executables and library files, + together with instructions (in the manual page or equivalent) on where to + get the Standard Version. + + b) accompany the distribution with the machine-readable source of the Package + with your modifications. + + c) accompany any non-standard executables with their corresponding Standard + Version executables, giving the non-standard executables non-standard + names, and clearly documenting the differences in manual pages (or + equivalent), together with instructions on where to get the Standard + Version. + + d) make other distribution arrangements with the Copyright Holder. + +5. You may charge a reasonable copying fee for any distribution of this +Package. You may charge any fee you choose for support of this Package. You +may not charge a fee for this Package itself.

This is why Xslate is +developed, which is the best template engine for web applications. + +The concept of Xslate is strongly influenced by Text::MicroTemplate +and Template-Toolkit 2, but the central philosophy of Xslate is different +from them. That is, the philosophy is __sandboxing__ that the template logic +should not have no access outside the template beyond your permission. + +Other remarkable features are as follows: + +## Features + +### High performance + +This engine introduces the virtual machine paradigm. Templates are +compiled into intermediate code, and then executed by the virtual machine, +which is highly optimized for rendering templates. Thus, Xslate is +much faster than any other template engines. + +The template roundup project by Sam Graham shows Text::Xslate got +amazingly high scores in _instance\_reuse_ condition +(i.e. for persistent applications). + +- The template roundup project + + [http://illusori.co.uk/projects/Template-Roundup/](http://illusori.co.uk/projects/Template-Roundup/) + +- Perl Template Roundup October 2010 Performance vs Variant Report: instance\_reuse + + [http://illusori.co.uk/projects/Template-Roundup/201010/performance\_vs\_variant\_by\_feature\_for\_instance\_reuse.html](http://illusori.co.uk/projects/Template-Roundup/201010/performance\_vs\_variant\_by\_feature\_for\_instance\_reuse.html) + +There are also benchmarks in `benchmark/` directory in the Xslate distribution. + +### Smart escaping for HTML metacharacters + +Xslate employs the __smart escaping strategy__, where a template engine +escapes all the HTML metacharacters in template expressions unless users +mark values as __raw__. +That is, the output is unlikely to prone to XSS. + +### Template cascading + +Xslate supports the __template cascading__, which allows you to extend +templates with block modifiers. It is like a traditional template inclusion, +but is more powerful. + +This mechanism is also called as template inheritance. + +### Easiness to enhance + +Xslate is ready to enhance. You can add functions and methods to the template +engine and even add a new syntax via extending the parser. + +# INTERFACE + +## Methods + +### __Text::Xslate->new(%options)__ + +Creates a new Xslate template engine with options. You can reuse the instance +for multiple call of `render()`. + +Possible options are: + +- `path => \@path // ['.']` + + Specifies the include paths, which may be directory names or virtual paths, + i.e. HASH references which contain `$file_name => $content` pairs. + + Note that if you use taint mode (`-T`), you have to give absolute paths + to `path` and `cache_dir`. Otherwise you'll get errors because they + depend on the current working directory which might not be secure. + +- `cache => $level // 1` + + Sets the cache level. + + If `$level == 1` (default), Xslate caches compiled templates on the disk, and + checks the freshness of the original templates every time. + + If `$level >= 2`, caches will be created but the freshness + will not be checked. + + `$level == 0` uses no caches, which is provided for testing. + +- `cache_dir => $dir // "$ENV{HOME}/.xslate_cache"` + + Specifies the directory used for caches. If `$ENV{HOME}` doesn't exist, + `File::Spec->tmpdir` will be used. + + You __should__ specify this option for productions to avoid conflicts of + template names. + +- `function => \%functions` + + Specifies a function map which contains name-coderef pairs. + A function `f` may be called as `f($arg)` or `$arg | f` in templates. + + Note that those registered function have to return a __text string__, + not a binary string unless you want to handle bytes in whole templates. + Make sure what you want to use returns whether text string or binary + strings. + + For example, some methods of `Time::Piece` might return a binary string + which is encoded in UTF-8, so you'd like to decode their values. + + # under LANG=ja_JP.UTF-8 on MacOSX (Darwin 11.2.0) + use Time::Piece; + use Encode qw(decode); + + sub ctime { + my $ctime = Time::Piece->new->strftime; # UTF-8 encoded bytes + return decode "UTF-8", $ctime; + } + + my $tx = Text::Xslate->new( + function => { + ctime => \&ctime, + }, + ..., + ); + + Built-in functions are described in [Text::Xslate::Manual::Builtin](http://search.cpan.org/perldoc?Text::Xslate::Manual::Builtin). + +- `module => [$module => ?\@import_args, ...]` + + Imports functions from _$module_, which may be a function-based or bridge module. + Optional _@import\_args_ are passed to `import` as `$module->import(@import_args)`. + + For example: + + # for function-based modules + my $tx = Text::Xslate->new( + module => ['Digest::SHA1' => [qw(sha1_hex)]], + ); + print $tx->render_string( + '<: sha1_hex($x).substr(0, 6) :>', + { x => foo() }, + ); # => 0beec7 + + # for bridge modules + my $tx = Text::Xslate->new( + module => ['Text::Xslate::Bridge::Star'], + ); + print $tx->render_string( + '<: $x.uc() :>', + { x => 'foo' }, + ); # => 'FOO' + + Because you can use function-based modules with the `module` option, and + also can invoke any object methods in templates, Xslate doesn't require + specific namespaces for plugins. + +- `html_builder_module => [$module => ?\@import_args, ...]` + + Imports functions from _$module_, wrapping each function with `html_builder()`. + +- `input_layer => $perliolayers // ':utf8'` + + Specifies PerlIO layers to open template files. + +- `verbose => $level // 1` + + Specifies the verbose level. + + If `$level == 0`, all the possible errors will be ignored. + + If `$level >= 1` (default), trivial errors (e.g. to print nil) will be ignored, + but severe errors (e.g. for a method to throw the error) will be warned. + + If `$level >= 2`, all the possible errors will be warned. + +- `suffix => $ext // '.tx'` + + Specify the template suffix, which is used for `cascade` and `include` + in Kolon. + + Note that this is used for static name resolution. That is, the compiler + uses it but the runtime engine doesn't. + +- `syntax => $name // 'Kolon'` + + Specifies the template syntax you want to use. + + _$name_ may be a short name (e.g. `Kolon`), or a fully qualified name + (e.g. `Text::Xslate::Syntax::Kolon`). + + This option is passed to the compiler directly. + +- `type => $type // 'html'` + + Specifies the output content type. If _$type_ is `html` or `xml`, + smart escaping is applied to template expressions. That is, + they are interpolated via the `html_escape` filter. + If _$type_ is `text` smart escaping is not applied so that it is + suitable for plain texts like e-mails. + + _$type_ may be __html__, __xml__ (identical to `html`), and __text__. + + This option is passed to the compiler directly. + +- `line_start => $token // $parser_defined_str` + + Specify the token to start line code as a string, which `quotemeta` will be applied to. If you give `undef`, the line code style is disabled. + + This option is passed to the parser via the compiler. + +- `tag_start => $str // $parser_defined_str` + + Specify the token to start inline code as a string, which `quotemeta` will be applied to. + + This option is passed to the parser via the compiler. + +- `tag_end => $str // $parser_defined_str` + + Specify the token to end inline code as a string, which `quotemeta` will be applied to. + + This option is passed to the parser via the compiler. + +- `header => \@template_files` + + Specify the header template files, which are inserted to the head of each template. + + This option is passed to the compiler. + +- `footer => \@template_files` + + Specify the footer template files, which are inserted to the foot of each template. + + This option is passed to the compiler. + +- `warn_handler => \&cb` + + Specify the callback _&cb_ which is called on warnings. + +- `die_handler => \&cb` + + Specify the callback _&cb_ which is called on fatal errors. + +- `pre_process_handler => \&cb` + + Specify the callback _&cb_ which is called after templates are loaded from the disk + in order to pre-process template. + + For example: + + # Remove withespace from templates + my $tx = Text::Xslate->new( + pre_process_handler => sub { + my $text = shift; + $text=~s/\s+//g; + return $text; + } + ); + + The first argument is the template text string, which can be both __text strings__ and `byte strings`. + + This filter is applied only to files, not a string template for `render_string`. + +### __$tx->render($file, \\%vars) :Str__ + +Renders a template file with given variables, and returns the result. +_\\%vars_ is optional. + +Note that _$file_ may be cached according to the cache level. + +### __$tx->render\_string($string, \\%vars) :Str__ + +Renders a template string with given variables, and returns the result. +_\\%vars_ is optional. + +Note that _$string_ is never cached, so this method should be avoided in +production environment. If you want in-memory templates, consider the _path_ +option for HASH references which are cached as you expect: + + my %vpath = ( + 'hello.tx' => 'Hello, <: $lang :> world!', + ); + + my $tx = Text::Xslate->new( path => \%vpath ); + print $tx->render('hello.tx', { lang => 'Xslate' }); + +Note that _$string_ must be a text string, not a binary string. + +### __$tx->load\_file($file) :Void__ + +Loads _$file_ into memory for following `render()`. +Compiles and saves it as disk caches if needed. + +### __Text::Xslate->current\_engine :XslateEngine__ + +Returns the current Xslate engine while executing. Otherwise returns `undef`. +This method is significant when it is called by template functions and methods. + +### __Text::Xslate->current\_vars :HashRef__ -Install cpanm (App::cpanminus) and then run the following command to install -Xslate: +Returns the current variable table, namely the second argument of +`render()` while executing. Otherwise returns `undef`. - $ cpanm Text::Xslate +### __Text::Xslate->current\_file :Str__ -If you get the distribution, unpack it and build it as per the usual: +Returns the current file name while executing. Otherwise returns `undef`. +This method is significant when it is called by template functions and methods. - $ tar xzf Text-Xslate-{version}.tar.gz - $ cd Text-Xslate-{version} - $ perl Makefile.PL - $ make && make test +### __Text::Xslate->current\_line :Int__ -Then install it: +Returns the current line number while executing. Otherwise returns `undef`. +This method is significant when it is called by template functions and methods. - $ make install +### __Text::Xslate->print(...) :Void__ -If you want to install it from the repository, you must install authoring -tools. +Adds the argument into the output buffer. This method is available on executing. - $ cpanm < author/requires.cpanm +## Exportable functions -# DOCUMENTATION +### `mark_raw($str :Str) :RawStr` -Text::Xslate documentation is available as in POD. So you can do: +Marks _$str_ as raw, so that the content of _$str_ will be rendered as is, +so you have to escape these strings by yourself. - $ perldoc Text::Xslate +For example: -to read the documentation online with your favorite pager. + my $tx = Text::Xslate->new(); + my $tmpl = 'Mailaddress: <: $email :>'; + my %vars = ( + email => mark_raw('Foo <foo at example.com>'), + ); + print $tx->render_string($tmpl, \%email); + # => Mailaddress: Foo <foo@example.com> + +This function is available in templates as the `mark_raw` filter, although +the use of it is strongly discouraged. + +### `unmark_raw($str :Str) :Str` + +Clears the raw marker from _$str_, so that the content of _$str_ will +be escaped before rendered. + +This function is available in templates as the `unmark_raw` filter. + +### `html_escape($str :Str) :RawStr` + +Escapes HTML meta characters in _$str_, and returns it as a raw string (see above). +If _$str_ is already a raw string, it returns _$str_ as is. + +By default, this function will be automatically applied to all the template +expressions. + +This function is available in templates as the `html` filter, but you'd better +to use `unmark_raw` to ensure expressions to be html-escaped. + +### `uri_escape($str :Str) :Str` + +Escapes URI unsafe characters in _$str_, and returns it. + +This function is available in templates as the `uri` filter. + +### `html_builder { block } | \&function :CodeRef` + +Wraps a block or _&function_ with `mark_raw` so that the new subroutine +will return a raw string. + +This function is used to tell the xslate engine that _&function_ is an +HTML builder that returns HTML sources. For example: + + sub some_html_builder { + my @args = @_; + my $html; + # build HTML ... + return $html; + } + + my $tx = Text::Xslate->new( + function => { + some_html_builder => html_builder(\&some_html_builder), + }, + ); + +See also [Text::Xslate::Manual::Cookbook](http://search.cpan.org/perldoc?Text::Xslate::Manual::Cookbook). + +## Command line interface + +The `xslate(1)` command is provided as a CLI to the Text::Xslate module, +which is used to process directory trees or to evaluate one liners. +For example: + + $ xslate -Dname=value -o dest_path src_path + + $ xslate -e 'Hello, <: $ARGV[0] :> wolrd!'
