That is strange. What happens if you just create the obj directory manually?

Re: [Mason] Poet Toolbar injection

In your app.psgi, there should be a line

enable "Debug”;

Remove that.

Re: [Mason] mason 2 extends and .mp files

Yeah, I don’t think there’s any way to do this, because the .mp gets an

entirely of the extends %flag and a %class section. :/

Any particular reason you need to keep using Apache, as opposed to (say)

Sorry, I don’t normally like to answer questions that way :), it’s just that

 Sure, now - when it is shortened, the error is clearly visible - the empty %

 What is strange, the error-message - what says:

 the line15 is the closing }} of the second filter. When removed the empty % 
 % the page is rendered OK.
 
 So, incorrect error detection.
 
 For curiosity, when remove the correct % $.title %, the error message 
 changes to usable one:
 
 whitespace required after '%' at /.../comps/tmp/index.mc line 5
 
 After this, i checked some variants:
 
 %% - (without space)  the error is:  '%' without matching '%' at
 % % - (one space): whitespace required after '%' at
 %  % - (two or more spaces): whitespace required before '%' at
 
 IMHO, if the % \s* % construction is intentionaly not allowed, it should 
 give a consistent error message - or at least - should NOT detected as an 
 filter }} closing error.
 
 Lastly - IMHO the % \s* % should be rendered as an EMPTY string.

In Poet::Mason it sets the default cache_root_class to Poet's Cache class:

method get_options ($class:) {

 Hello,
 
 We wanted to start using Poet::Cache in our application and discovered a 
 really weird problem. Following manual from here 
 (http://search.cpan.org/~jswartz/Poet-0.10/lib/Poet/Cache.pm), we need to 
 configure default cache store - I did it for Memcached, in global.cfg:
 
 cache:
 defaults:
  driver: Memcached
  servers: [127.0.0.1:11211]
 
 Then I should just start my app and use $m-cache in Mason components, right? 
 The problem is - whenever I use $m-cache, it uses File driver instead of 
 Memcached. I checked and it looks like Poet::Cache works well when used from 
 scripts or Perl modules (it loads correct cache object), but for Mason 
 components its always default File cache.
 
 This led me to Mason::Plugins::Cache and I realized that I have no idea how 
 this class works together with Poet's caching. It seems that the problem lies 
 somewhere in between - Poet's configuration is not passed correctly to 
 Mason::Plugin, but why?

Re: [Mason] dhandler calls function defined in another dhandler, why?

[Jonathan Swartz]

All HTML::Mason components are defined in the same package, so you should not 
use named subroutines. Use anonymous subroutines instead.

Re: [Mason] Trouble capturing the values of multi-select form elements

Are you using Poet? If so this might help:

 Hi,
 
 I'm new to mason2. In html::mason it was fairly easy to capture the 
 values of a multi-select formfield in the receiving component. Now, when 
 I post values only 1 value is received. Same problem occurs when I use a 
 checkbox that can be ticket more than once.
 
 This is my form:
 
 form action=query_design method=post
 select name=table_classes multiple=multiple
 option value=table-borderedtable-bordered/option
 option value=table-condensedtable-condensed/option
 option value=table-hovertable-hover/option
 /select
 button type=submit name=submit value=OKOK/button
 /form
 
 This is a piece of code in the receiving component 'query_design.mc', 
 testing whether a list or a scalar variable is received:
 
 % my @list;
 % eval { @list = @{$.table_classes}; }; # check if list is received
 % if ( !$@ ) { # It is indeed a list
 %   for my $i ( @list ) {
 listvalue--% $i %br
 %   }
 % } else { # It's a scalar
 % $.table_classes %
 % }
 
 Now, even when i select all 3 values in the select field 
 'table_classes', only 1 value is received. So no list...
 
 In html::mason I could grab the values as a list in this way!
 
 Question: how to capture all the values of multiselect form fields in 
 the receiving component?
 
 Kind regards,
 
 Wil Peters.

Re: [Mason] Component from a string?

[Jonathan Swartz]

I haven't thought about how to do on-the-fly component compilation in Mason 2 
yet. It made the code a lot cleaner not to have to plan for it, and I wasn't 
sure if anyone would need it. :)

It should be possible since Class::MOP and Moose have utilities for creating 
classes on the fly. Let me know if you come up with a good solution.

 Index files are for being displayed, when a directory is hit. Having
 them only displayed when allow_path_info is set is like having to define
 allow_path_info inside of all dhandlers.

Agreed.

Re: [Mason] index files do not work on 2.20 if allow_path_info is not set

[Jonathan Swartz]

Oliver - I think you're right, this was a mistake. It was the result of

   https://github.com/jonswar/perl-mason/issues/8

I'm not sure what the right behavior should be. For the sake of good SEO, you 
generally want canonical urls and it's suboptimal to allow /foo/bar and 
/foo/bar/ to map to the exact same thing. One of them should redirect to the 
other. In the old Apache world, /foo/bar would redirect to /foo/bar/, but these 
days it is much more common to have urls without trailing slashes.

Feedback welcome. I agree, though, the current situation is very un-DWIM-ish.

 Hi
 
 while reading through latest Mason::Manual::RequestDispatch and
 Mason::Interp::_build_match_request_path to understand trailing slash
 handling I found that my installation was Mason-2.19 and latest was 2.20
 with the trailing slash change for directories.
 
 So I updated and everything looks broken now. ;-)
 
 As far as I can see an access to a directory with trailing slash
 (except / itself) will never match an index.mc until allow_path_info is
 set to 1.
 This is the only way to get the check  in _build_match_request_path for
 index.mc valid, because path_info now is '/' and it is not a dhandler.
 
 This is really bad, what was the reason to do it this way?
 Maybe the simplest fix could be a check similar to is_dhandler like
 is_index to get index files delivered without allow_path_info set.
 
 From my point of view (is_index and path_info eq '') could lead to a
 redirect adding a slash to path if attribute force_directory_slash is
 set.

Re: [Mason] Passing complex GET parameters to Mason2

[Jonathan Swartz]

$.args ($self-args) will return a hashref of arguments passed to a component. 
It's like %ARGS, except that it's a method call rather than a magic scalar.

 Hello,
 
 We ran into a problem recently – we have quite complex form that is used to 
 edit multiple rows of data. This means we have input structure like this:
 
 input type=text name=row_1 /
 input type=text name=row_2 /
 input type=text name=row_n /
 
 There can be also additional data related to each row so:
 input type=radio name=row_1_type /
 input type=radio name=row_1_category /
 
 With old Mason we could just use %ARGS and process it manually with regexps 
 and create nested array-hash structure:
 
 [0] = { name = …, type = …, category = … },
 [1] = { name = …, type = …, category = … },
 [n] = { name = …, type = …, category = … }
 
 But Mason2 uses Moose constructor and requires parameters to be defined as 
 attributes – its obvious defining every possible number of such row data will 
 be very tedious and ugly:
 
 %class
 has 'row_1_name';
 has 'row_1_type';
 has 'row_1_category'
 .
 .
 .
 has 'row_n_name';
 has 'row_n_type';
 has 'row_n_category'
 /%class
 
 How to solve this problem in a Mason2 way? Some frameworks allow to use 
 naming convention with square brackets that describe nested nature of input 
 data:
 
 input type=text name=row[1][name] /
 input type=radio name=row[1][type] /
 
 etc. but I don't think Mason2 supports this. Would it be possible to create 
 some pre-processing method that would prepare data in such format for passing 
 into Moose constructor, so we could use more advanced Moose attributes for 
 GET data, and just pre-process it before it reaches the actual component? Or 
 is there a better way?
 
 Other way to do this I think is to use class meta methods and just create 
 needed attributes on runtime, this would save a lot of typing, but we still 
 are not flexible, as we need to generate certain number of input rows, and if 
 we receive one more row it will break. 
 
 Mason2 is great so far, but sometimes we run into problems when doing more 
 advanced stuff thats not described anywhere. Hope someone can point us in the 
 right direction.
 
 Regards,
 KN

Re: [Mason] Mason 2 and Dancer error.

[Jonathan Swartz]

Don't know. So I assume it works with simple template, but not with Mason?

The stack trace isn't helpful, unfortunately, as it doesn't mention who is 
calling Memoize::flush_cache.

This is naturally a Poet/Mason site, albeit a very simple one - the source is

 All i need is a clean HTML/CSS home page and skeleton, with logo and color

 You'd be saving hours of painful effort for me. I'd be happy to return the

This ought to be easy to do, as it's a common need.

You can certainly do this in /eshop/warenkorb/versand:

but that's tedious, there ought to be a way to create a single configuration 
table and handle this all at a higher level just before control enters Mason.

 I think basically all the perl sections should combine with all the inline

 more HTML
 %perl
 another block 
 /%perl
 
 /%method 
 
 % other inline mason back in main component
 %perl
 perl in main component
 /%perl
 some embedded HTML in main component
 
 I probably do nonsense like that, but if I do I should really be moving 
 those methods to the end of the component.
 
 
 
 When running masontidy on a sample file I get a lot of output like 
 Ignoring -b; you may not specify a destination stream and -b together.  
 Not sure what that means, but I assume it is something from perltidy.
 
 No idea, did you put -b in your perltidy options list? You shouldn't need to.
 
 I am an idiot - I forgot there even WAS a local .perltidyrc.  I haven't used 
 perl tidy on that project in years.  Thanks!
  
 When building on a Windows machine the generated .bat file works fine, but 
 the generated native perl has the wrong #! line in it.  Not sure if there 
 is a way to fix that, but if there is then it would work right when called 
 from a Cygwin shell on Windows (I use that for a development environment 
 sometimes).
 
 I just have #!/usr/bin/perl at the top of bin/mason, I've always thought 
 that was the correct thing to put. I don't have a Windows environment but 
 let me know if you figure out a way to fix it.
 
 I will give it a think.

 perl tidy on that project in years.  Thanks!
  
 When building on a Windows machine the generated .bat file works fine, but 
 the generated native perl has the wrong #! line in it.  Not sure if there is 
 a way to fix that, but if there is then it would work right when called from 
 a Cygwin shell on Windows (I use that for a development environment 
 sometimes).
 
 I just have #!/usr/bin/perl at the top of bin/mason, I've always thought that 
 was the correct thing to put. I don't have a Windows environment but let me 
 know if you figure out a way to fix it.
 
 I will give it a think.

 Well, I am ;-). The most useful part is automatic indentation. I guess that
 your recently announced masontidy could help in that regard.
 
 Further along the awesomeness scale: For pure perl scripts, I find
 flymake very useful. Imagine having on-the-fly syntax checking while
 writing Mason2 code! I guess this would have to activate the mason
 compiler behind the scenes somehow. Is this possible?

You can call

   $interp-_compile($source_file, $path)

where $source_file is the component file and $path is the component path. The 
latter doesn't really matter for validation purposes.

This wlil return the generated class that would normally go into an object 
file, or throw a fatal error if there was a syntax problem.

There ought to be a public API method for this, but I'm not sure the existing 
_compile is the right level to expose.

Give it a try and let me know.

Ah. I'll just have to generate an empty .perltidyrc and point it explicitly to 
that in the tests.

Where was your .perltidyrc? I couldn't reproduce this. It looks for

[Mason] Mason tidy

[Jonathan Swartz]

File under ought to have been written ten years ago, but oh well:

https://metacpan.org/module/masontidy

masontidy tidies the Perl code embedded in Mason components. It works with 
%-lines, % % tags, and the various Perl blocks, in both Mason 1 and Mason 2 
syntax.

It does not (yet) attempt to tidy the HTML or other non-Perl content in a 
component.

See below for an example. Please give it a try (make sure you have backup!) and 
let me know of problems.

Re: [Mason] Mason2: Filter (component with content) syntax

[Jonathan Swartz]

Hi Roman,

There are two separate issues here: (1) where are filters defined, and (2) how 
are they applied.

1. In Mason 2 filters are defined by methods, rather than by components. This 
makes sense for a large variety of filters that don't output content of their 
own but simply process their incoming content in some way. e.g. an uppercase 
filter:

method Upper () {
return sub { uc($_[0]) }
}

However, it is still possible to define a filter out of a piece of component, 
e.g. your example of a Javascript filter that wraps its input with a script tag:

%filter Javascript
  script type=javascript
% $yield-() %
  /script
/%filter

2. As you know the main syntax for applying filters is with perl lines, e.g.

% $.Upper {{
some text that will be uppercased
% }}

I chose this because it seemed like a similar situation to other 
brace-delimited control structures: if, for, while, etc.

However, there is an another syntax for applying filters that is still 
supported, though currently not documented:

% $.Upper { % some text that will be uppercased % } %

I think this is more like the inline markup you are looking for. It is too 
much tag soup for me, but if people like it for certain situations then we 
could leave it officially supported and document it.

Jon

 In my old code I had components (methods) with content which served as
 an active markup adding some real markup before and after block of
 text without any changes to the content. Examples:
 
 | SELF:javascript 
 javascript to be properly wrapped by script tag, CDATA section and
 jquery onDomReady wrapper
 /
 
  SELF:elem, ($important? 'strong': ()) text to be empasized or not/
 
  SELF:elem, ($active? ('a', href=$edit_url): ()) text to be make
 link or not/
 
 
 I appreciated that the old syntax was visually similar to HTML markup
 and could be placed (indented) accordingly.
 
   td SELF:elem, ($active? ('a', href=$edit_url): ()) text to
 be make link or not//td
 
 Is there some similar syntax for active markup, not actually
 changing its content, available also in Mason2?
 
 Thanks for reply,

Re: [Mason] Running multiple Mason scripts

[Jonathan Swartz]

Hi Marc - just working through email backlog and noticed that this went 
unanswered.

First of all, as you may have noticed, all the psgi/plack Mason support has 
moved to Poet, so I'd suggest you look there if you are still pursuing this.

If you have several different sites, I think it is cleanest to have a separate 
Poet environment for each of them, with its own app.psgi and Mason component 
root. You can run them on different ports and have an nginx or similar running 
in front that maps domain names to different ports. This is what I do on my own 
servers.

HTH,
Jon

 Hi folks,
 
 I'm wondering that here is any preferred/recommentd component
 distribution method?
 

Display components tend to be site and application specific; I've never figured 
out a way to package them generically. I think the best thing to do for now is 
publish components, or entire example Mason/Poet sites, on github and let 
people pick out what they need.

 The second question is about the html-template separation.
 
 E.g. What is the best way having an separate directory, e.g.
 /templates, where one can put some _poet-specific_ site-templates,
 together with template-specific methods, css, js and etc.. and the
 main execution flow only fill the template as one of last actions -
 probably from /Base.mc.
 
 How to implement for example:
   http://example.com/some/component?template=print
 
 e.g. in the normal execution flow the site will use some default
 template, but when get the arg template=print (or any other
 template-name) will search the /templates for the requested
 template (like print) and will use/fill that one...
 
 I understand than this is too application specific, and some apps
 simply doesn't need this, but would be nice have some hints, what is
 the right way to do this tasks like this. Is the right way using
 subrequests here with $m-visit ? Any other hints?

Yes, I think $m-visit is the right way to do this.

Yes, right now there are a number of singletons in Poet: the environment, the 
configuration, and the Mason interpreter. This is easiest and most convenient 
in the common case, but obviously there's more than one person who would like 
multiple Poet object sets per process...

Unfortunately I'm not in this situation right now, so the solution is likely to

[Mason] new Mason/Poet site - help wanted

[Jonathan Swartz]

I want to create a new Mason/Poet site to replace the current masonhq.com. I 
see it along the lines of sites like

   Moose (http://moose.iinteractive.com/)
   PSGI/Plack (http://plackperl.org/)
   Dancer (http://perldancer.org/)

i.e., much less ambitious and self-contained, mostly some nice marketing, a few 
menu items, and links off to search.cpan.org and github. I'll also host the 
existing frozen wiki content for archive purposes.

The problem is, I am *really* bad and slow with website design, it's way too 
open-ended for me and I am effectively style-blind. So I'm asking for help from 
some dedicated/grateful Mason user(s) out there with some design sense. All i 
need is a clean HTML/CSS home page and skeleton, with logo and color choices, 
and I can add any additional pages. :)

You'd be saving hours of painful effort for me. I'd be happy to return the 
favor by working on your favorite features/documentation, by giving you 
personalized help in converting your existing Mason 1 site, etc. And hopefully 
it will lead to more adoption/retention for Mason.

Let me know - thanks!

Re: [Mason] Mason advantages

[Jonathan Swartz]

Hi Marc,

As the author I'm obviously biased, but I'll give you my take on the three key 
differences between Poet+Mason and analagous combos, e.g. Catalyst+TT, 
Dancer+TT, and Mojolicious.

1) Builds upon the best of CPAN

Poet+Mason depends proudly on Moose and Plack/PSGI (as well as a few other 
best-of-breed CPAN distributions). Being able to depend on the presence of 
these powerful modules means that we get quite a lot for free, and can focus on 
interesting features instead of reinventing the wheel. Mason components compile 
down to Moose classes. Mason and Poet plugins are Moose roles. Poet freely 
takes advantage of PSGI middleware and uses the Plack::Request/Plack::Response 
objects as a base request/response API.  There aren't separate branches of code 
or feature sets or documentation for Moose/non-Moose users or for PSGI/non-PSGI 
users.

In contrast, Dancer and Mojolicious are proud of their lack of dependencies, 
because it makes installation easier; true enough. But this means a lot of 
wheel reinvention and divergent usage patterns depending on what is present. 
Dancer, for example, invents its own before/after hooks and its own base 
request/response API. Mojolicious, with its zero dependency promise, has to 
reinvent everything for its baseline behavior.

Some people do seem afraid of the cost of Moose installation and of largish 
installation chains in general. So for them, the lack of dependencies is an 
advantage. My feeling is that tools like local::lib and perlbrew and cpanm and 
Pinto and Carton make it increasingly easy to control the Perl and CPAN 
environment that your application uses (with or without root access), so why 
not depend on the best?

2) Perl-based template language

Mason does not attempt to invent a new programming language syntax for 
templates.  It is just Perl, wrapped with just enough extra syntax and features 
to facilitiate templating. Mason components compile into Moose classes in an 
obvious way.

This gives Mason templates enormous power (whatever Perl can do, Mason can do) 
and just as importantly, predictability - if you know Perl and Moose then you 
know how your components will behave, and if you forget how a piece of Mason 
syntax translates, you can just look at the compiled class or walk through with 
the Perl debugger.

In contrast, TT is really is a separate language that you have to learn and 
understand.  It is well-designed in some aspects, but is undeniably (and 
intentionally) weak compared with Perl and has a number of well-known quirks 
(e.g. with variable scoping).

One purported advantage of TT over Mason is that it is friendlier for 
non-programmers (e.g. designers). Another is that its weakness as a programming 
language is actually a strength, in that it encourages you to put complex code 
into Perl classes.

The paragraphs above apply equally to HTML::Template, except it is even further 
along the intetionally-weak/quirky/designer-friendly spectrum.

3) Combined controller and view

In most frameworks the controllers and views are strictly separated. A 
controller gathers data from appropriate model(s), then constructs a hash of 
data and passes it to a template to render the page.

In theory the controller method and template are decoupled, so that you could 
create multiple templates for a single controller method (one for browser, one 
for mobile, etc.).

In practice, you almost never do this; there is one template per controller 
method, and the two *are* quite coupled. If you want to figure out how a page 
is rendered, you have to look at both the controller and view. If you want to 
change how the page is rendered in any meaningful way, you have to modify both 
the controller and the view. So with Catalyst development you constantly having 
to look in, and edit, two places at once. You also have more decisions to make 
about which code goes where.

In Poet+Mason, it's very clear which component handles a URL, and that 
component contains both the controller and the view. You only have to look in 
one place and modify things in one place, and you aren't wasting time packing 
and unpacking a stash in between two coupled pieces of code.

Catalyst and MVC devotees would say that the separation between C and V is 
valuable, to ensure you aren't doing too much in templates. Whether this 
applies when said templates compile to full OO classes is less clear.

Hope that helps!

 Are you talking about a speed issue besides startup speed?
 
 Honestly, I'd surprised if Mason 2 was significantly slower than Mason 1 
 at run time.

Mason 2 is noticeably *faster* than Mason 1 in terms of raw component call 
speed. This is because Mason 1 component calls did a bunch of custom stack 
maintenance and so on, whereas in Mason 2 it is pretty much 
component_class-new(@args)-run().

Mason 2 is probably slower to startup than Mason 1, like anything that uses 
Moose. I can't get real worked up over this. I use Moose for all sorts of stuff 
and the startup speed never seems to bother me. I guess I'm not running lots of 
tiny scripts real frequently?

Need to rerun and publish these benchmarks.

Re: [Mason] Mason2: no default HTML escaping

[Jonathan Swartz]

 As you noted, escaping by default would be fine and largely a non-argument if 
 Mason were explicitly a Web template language, but it's not.
 

I'm confused Stephen, because this statement seems to contradict your other 
statement that escaping by default never works right, because too many 
templates contain a mix of html, javascript, css, etc. and that this is 
action at a distance (paraphrasing).

Mason is not explicitly a Web template language, but Poet *is* explicitly a web 
framework and reserves the right to tweak Mason settings appropriately. So it 
might well be reasonable to turn on HTML escaping by default for Poet.

In any case, it seems like default escaping is a reasonable feature for Mason 
to make available sans any scary caveats. Though ideally you'd be able to turn 
it on/off on a component or a directory basis, or even on a partial-component 
basis, rather than a giant on/off switch for your whole site. 

If a thoughtful framework like django does this by default, then I'd say it's a 
pretty good bet Poet ought to as well.

Re: [Mason] Mason2: no default HTML escaping

[Jonathan Swartz]

 I think the default for text outside a %perl block should be HTML style 
 escaping, since it seems that most Mason2 apps are web apps and most non-web 
 Mason2 apps would need some sort of Perl to generate their output (and there 
 is always the here-doc for boilerplate text).

Have to disagree, I use Mason to generate httpd.conf files all the time. In 
fact Poet will have a plugin to do just that.

But for the specific Mason interpreter that Poet creates to answer web 
requests, I am leaning towards escaping html by default, as long as there are 
various convenient ways to turn it off.

Re: [Mason] Trouble Installing Poet

The latest Moose (2.06) broke Mason pre-2.19 in a big way; I was importing

Hence, lots of errors about attibutes.

Please upgrade to the latest Mason and try again. Let me know if this does not

Re: [Mason] Odd session behaviour - plackup vs starman

Please keep replies on the mailing list, thanks.

You need to use $session-set and $session-get. Otherwise you are just setting

plackup.

You need to use the File store for the same reason - Starman has multiple

I still think it is difficult to est this default, given that substitution tags 
can be used when generating javascript, JSON, css, etc. even in a web 
environment.  At the very least we'd need the ability to turn the default 
on/off on a per-component or directory basis, rather than for an entire site.

 
 2) DefaultFilter should be implemented and documented in core Mason, so that 
 it doesn't require a separate plugin install.
 
 I think this should happen either way. Maybe not move into the core,
 but at least document it, and remove the big scary CAVEAT section from
 the DefaultFilter docs (I know its not your module, but I think if you
 suggested it to Stephen he would agree).

For now, I've added DefaultFilter to the Mason documentation in multiple places.

 The previous paragraph, and the fact that we can't target components
 to specific HTTP methods (like Dave mentioned in the GET/POST
 parameters thread), argue that the Mason dispatcher is a bit too
 limited. I have mixed feelings about it. On one hand I like that its
 simple, just drop files into a directory and you are done. On the
 other, if we could add route filters for HTTP method, mime/type and/or
 others, we could tweak the defaults for each request, and provide
 saner HTTP error codes.


The Mason dispatcher will probably always be feature-light compared with other 
frameworks. But adding the ability to filter on GET/POST does seem reasonable. 
Suggestions on syntax welcome. It could be a class method, e.g.

CLASS-allow_http_methods('POST');

or perhaps Mason looks for specifically named methods, e.g.

method handle_POST {
...
}

[Mason] Poet: a web framework for Mason

[Jonathan Swartz]

I'm pleased to announce Poet, a modern Perl web framework designed especially 
for Mason developers:

http://search.cpan.org/perldoc?Poet

Features include:

   * A common-sense directory hierarchy for web development

   * A configuration system that scales elegantly with multiple coders and 
multiple layers (development/production)

   * Integration with PSGI/Plack for server APIs and engines

   * Integration with Log::Log4perl for logging, wrapped with much simpler 
configuration

   * Integration with CHI for powerful and flexible caching

   * Easy access to common objects and utilities from anywhere in your 
application

   * And of course, the power of Mason, for request routing and content 
generation.

Poet was designed and developed over the past six years at Hearst Digital 
Media. Today it is used to generate Hearst's magazine websites (including 
Cosmopolitan, Esquire and Good Housekeeping) as well as many internal systems. 
I'm very grateful to Hearst for agreeing to this open source release (though 
they bear no responsibility for its support or maintenance).

Some people nowadays use Mason as a view layer in a large MVC framework (i.e. 
as a replacement for TT), and that's just fine, even if it leaves some of 
Mason's features untouched.

But Poet is a web framework for those who, like me, think Mason is a great way 
to handle the *whole* web request, not just the view layer. For those who like 
their page logic right next to their template, MVC doctrine be damned. Poet 
just turns web requests into Mason requests, and happily lets Mason handle the 
rest of the work. At the same time it provides the web development structure 
and utilities that Mason, as a templating system, has always felt obligated 
to omit.

There's much more to come than I could put in this initial release, and I'm 
looking forward to pressing on with it!

Feedback welcome as always.

 #1 is hard to do because Mason is supposed to be content-type agnostic -

 Here is a question to ponder.
 
 Mason, it seems, was born originally with the idea in mind for 
 generating web pages.  Tools that are generic have their place, but so 
 do tools that specialize.  Tools that specialize can implement 
 optimizations since they do not have to consider possibilities outside 
 their specialty.  Case in point is the question of HTML filters in the 
 Mason core.
 
 So, the question is: Has anyone used Mason for anything serious other 
 than web page generation?  If the amount of people or projects using 
 Mason that are not web based is essentially zero, it may be better to 
 add web specific features and optimizations.
 
 I do not know the answer to this question, except my own experience, 
 which is that 100% of my Mason projects are for the web.

I use Mason to generate httpd and other conf files at work.

You're probably correct, though, that 99% of Mason's use is in generating web 
content. However, that isn't always HTML pages; I've used it to generate 
javscript and JSON results too, where HTML escaping would definitely be 
unwelcome.

So I think it's better to have a well-supported, easy way to html-escape all 
substitution tags than to put this in as the global default.

 The default filter is defined in the interpreter instance. If you need
 to use Mason to generate any type of content, you can perfectly have
 different interpreters with different default filters. Anything wrong
 with that?
 

Nothing wrong with that. It's fine to be able to set a default filter in each 
interpreter. I just don't think it can be the default for Mason out of the box.

 If users really insist on having the same Mason interpreter to render
 different types of contents, maybe the default filter should be a
 property of the component? Define it in Base.mc for your HTML
 generating component directory .. job done.


That would be nice. The problem is that the default filter affects compilation 
of the component (in particular, it affects how % % tags are converted to 
Perl) so it isn't a simple call you could put in the %class section, for 
example - it would have to be a %flags, and currently there is no way to 
inherit those.

But I agree, it's appealing to be able to set the default filter on a 
per-component basis, just for the components that output HTML. Would just like 
a better syntax than

   %flags
   default_filters = ['H']
   /%flags

Yuck.

2) DefaultFilter should be implemented and documented in core Mason, so that it 
doesn't require a separate plugin install.

#1 is hard to do because Mason is supposed to be content-type agnostic - usable 
for HTML generation but also other kinds of content generation.

#2 is more reasonable.

 I Agree with Pedro. Being able to define a default filter and
 explicitly choose another one (or none) when needed is much better
 from a security point of view, but also for programming convenience
 (who said I'm lazy at typing | html ? :)).
 
 After all, software that uses default settings (right now I'm thinking
 of Catalyst's default model or default view) is not so uncommon..

Re: [Mason] Can Mason be used without a server?

[Jonathan Swartz]

Well, you need a server of some kind to create a web interface, but there are 
*very* simple servers nowadays, e.g. servers that fit inside a single Perl 
process.

Have you tried getting this to work on your local machine:

 Yes, sadly Dave is one of those that believe in a separate controller layer 
 in modules. They are all wrong, but they comprise about 90% of the Perl 
 community so what can you do :p
 
 Could you explain your opinion about this They are all wrong a bit more ?

Nic Wolff summarized this pretty well, but I'll give my spin.

In Catalyst, URLs are handled by controller classes. A controller gathers data 
from appropriate model(s), then constructs a hash of data and passes it to a 
template to render the page.

In theory the controller method and template are decoupled, so that you could 
create multiple templates for a single controller method (one for browser, one 
for mobile, etc.).

In practice, there is almost always a one-to-one correspondence between 
controller method and template, and the two *are* quite coupled. If you want to 
figure out how a page is rendered, you have to look at both the controller and 
view. If you want to change how the page is rendered in any meaningful way, you 
have to modify both the controller and the view. So I find that with Catalyst 
development I'm constantly having to look in, and edit, two places at once. I 
also have more decisions to make about which code goes where.

In Mason, URLs are handled by components. A component gathers data from 
appropriate model(s), then renders the page itself. You only have to look in 
one place and modify things in one place.

Now with Mason 1 one could make a case that it's better to put logic in real OO 
classes whenever possible. With Mason 2, components *are* Moose classes; you 
get just as much OO power and goodness in a component as you do in a class. For 
example, a component can have a BUILD method that sets up attributes based on 
URL, params etc., and a number of render methods that refer to those 
attributes. This is a much richer controller-view interaction than passing a 
hash between two completely separate pieces of code.

Re: [Mason] www.masonhq.com back to work?

[Jonathan Swartz]

 
 I've little interest in trying to make Mason 2 lightweight enough for 
 standard CGI.
 Honestly given the ready availability of mod_perl, FastCGI, and Starman, I 
 don't
 understand why standard CGI is even considered a viable option anymore (but 
 I'm sure
 diehard CGI fans will yell at me for saying this).
 
 I need to deply on my $4 per century hosting, but I need to use all the 
 latest software, and I expect everything to just work even though I can't 
 install CPAN modules, get a shell, or use more than 8MB of memory.
 
 Of course, while I joke, this is exactly why PHP has been so insanely 
 popular, so there's a lot to be said for actually making this work.

Yes, and I'm glad some other Perl solutions make an effort to work in a 
lightweight environment. (I know Mark Stosberg has long been the champion of 
plain CGI users for example). I'm just not interested in competing in this 
space myself. I'd rather cater to the power users that have a reasonably robust 
hosting solution and don't mind installing a few dependencies.

 Use Catalyst, Dancer, or some other framework that supports all of these

Plack/PSGI supports all these deployment modes, in fact it's kind of their 
raison d'etre. You don't
need Catalyst/Dancer for that. (In fact one of the things that bother me about

 do with Mason so that it will not utilize some of the slower Moose features?
 
 Moose doesn't have a FAQ, so I'm not sure what you're referring to.
 

search.cpan.org/perldoc?Moose::Manual::FAQ sure looks like one :)

 
 Here's some other possibilities ...
 
 * Nobody is using Mason 1 _or_ 2. They've all moved on to 
 Template::Declare, Quicksilver, and Ruby on Rails. Rails is for cool 
 people. Those of us still on the list are totally unhip losers.

I'd rephrase that as follows: Few people are using Mason or Perl for *new* web 
development projects; the've all moved on to Rails and Django. At least that's 
what I observe from my perch in San Francisco, which admittedly has a higher 
than normal share of hip people and startups.

Compare these pages to see what I mean:
http://sfbay.craigslist.org/search/jjj/sfc?query=perlsrchType=T
http://sfbay.craigslist.org/search/jjj/sfc?query=railssrchType=T

I know this is only one datapoint, but it's one that's very relevant to my life 
and has been moving in the wrong direction for a while.

Nonetheless, I'm still hopelessly devoted to Perl and so seek out the few jobs 
that feature it. :)

 * Mason 1 is very stable, and it has good documentation. People are happy 
 with it for now, and so aren't jumping to use a new templating system, 
 even one named Mason 2.

Yes.

And just so everyone understands where my expectations are at: I didn't 
*expect* a whole bunch of people to jump to Mason 2 any time soon (if ever). It 
was not that kind of mild upgrade. It's a big leap, something of an experiment, 
possibly a little before its time (given that Moose and especially Plack/PSGI 
are still maturing), more like a whole new templating system with a similar 
syntax than an upgrade as its name might suggest. I briefly thought about 
changing the name, but I'm too fond of this one.

 * The list was a lot more active in the days when people used Mason as 
 their entire web framework, often paired with mod_perl. I can't 
 count the number of threads we've had about mod_perl issues.
 

Yes. Take a look at the mailing list archives during the peak - e.g. 
http://marc.info/?l=masonr=1b=200010w=2 - and notice how many questions are 
not about Mason per se but rather mod_perl and Perl web development in general. 
I too see a lot of those same discussions in the Catalyst list now.

 Nowadays, the action has moved on to other places, like the Catalyst list. 
 People still use Mason 1 and/or 2, but it's a much smaller part of their

Re: [Mason] www.masonhq.com back to work?

[Jonathan Swartz]

 
 I do understand that much of this delay with Moose is startup and that 
 by pulling various tricks, like FastCGI or mod_perl, performance can be 
 improved past the first invocation.  I have not run a comparison test 
 using mod_perl or FastCGI yet.

Yes, much of the delay is startup - I'd be interested to see a comparison test 
with a persistent Perl environment. In my brief benchmarks Mason 2 was actually 
*faster* than Mason 1 in terms of component call overhead, because it is 
leveraging Moose's optimizations for constructors and method calls as opposed 
to implementing its own call stack etc.

FastCGI and mod_perl aren't tricks, they are the most basic common sense 
implementation choices. As in, not starting a Perl interpreter and loading all 
your modules and reinitializing your world for every request. It's like saying 
I don't feel like using a compiler and this hand-interpreted C is really 
slowing me down. :)  I don't begrudge you for using plain CGI in your 
environment if it works for you, but is it an important benchmark point for 
modern web development?

Check out http://search.cpan.org/perldoc?Starman for a really easy 
high-performance persistent engine to use with Plack/PSGI.

 However, note that Jonathan's rationale for stripping out the web code 
 and using Plack is that it allowed Mason 2 to run under a wide variety 
 of platforms and servers, not just Apache with mod_perl.
 
 http://search.cpan.org/~jswartz/Mason-2.15/lib/Mason.pm
 
 Under acknowledgements: Thanks to Tatsuhiko Miyagawa and the PSGI/Plack 
 team, who freed me from ever worrying about server backends again.

True, but plain CGI was honestly not on the list of things I was worrying about 
in the first place. :) Someone else had to write the CGI handler for Mason 1.

 
 Has anyone profiled Moose to find out what is actually taking so much 
 time?  I know this was done with PHP5 and a lot of the slowness (which 
 turned out to be in the way PHP4 created objects) was addressed.
 

I'm fairly sure the Moose team has profiled and optimized a whole bunch. AFAICT 
they are not *unconcerned* about performance, but their top priority is 
creating the most powerful post-modern OO system they can and that has a cost.


 I have not tested Mouse yet, but I plan to, however, the Mouse 
 documentation states it is 4 times faster than Moose.  I was going to 
 contact the author to find out what Moose has that Mouse omits to see if 
 anything Mason critical is missing.  Of course, Jonathan would be a 
 better choice to ask that question since he would know better than I if 
 any missing features might cause a problem.

I tried using Mouse once (for CHI) and backed out quickly. There were too many 
compromises IMO to ensure compatibility between Mouse and Moose. Again, to beat 
this into the ground, the main (only?) thing Mouse saves is startup time and 
that's just not important to me in a web context where you can have a 
persistent Perl interpreter. Obviously it is more important for people using 
Mason in a non-web context.

Hi Roman,

 I wanted all my templates to be considered utf8 source files. But I didn't

 /%class
 
 in each template.
 
 So I created custom Interp class and overwrote 
 Mason::Interp::write_object_file

 my ( $this, $object_file, $object_contents, @rest ) = @_;
 
 $object_contents = use utf8;\n$object_contents;
 return $orig-( $this, $object_file, $object_contents, @rest );

 But I found very quickly that this little modification broke my inheritance. 
 The reason was that generated code relies on # FLAGS comment to be at the 
 very first line of the object file:
 
 # FLAGS: {extends:/Page.mc}
 our ($_class_cmeta, $m, $_m_buffer, $_interp);
 BEGIN {
 local $_interp = Mason::Interp-current_load_interp;
 $_interp-component_moose_class-import;
 $_interp-component_import_class-import;

 I modified the custom class and put use utf8 after FLAGS line if present:
 
 around write_object_file = sub {
 my $orig = shift;
 my ( $this, $object_file, $object_contents, @rest ) = @_;
 
 # all content files are utf8
 # 2012-01-22 we must respect the flags
 $object_contents =~ /^(?:#\s*FLAGS.*?\n)?/sg;
 $object_contents =~ s/\G/use utf8;\n/;
 
 return $orig-( $this, $object_file, $object_contents, @rest );
 };
 
 It works but I am not sure how reliable this method is. Aren't there any 
 other lines except of FLAGS which further processing relied upon?
 
 Thanks for any reply

Re: [Mason] Mason2 Help

[Jonathan Swartz]

I've reproduced this on my server. The right content is being returned, but 
with a httpd/unix-directory content type.

   swartz GET -eSs http://localhost:2400
   GET http://localhost:2400 -- 200 OK
   Connection: close
   Date: Wed, 14 Sep 2011 18:10:50 GMT
   Server: Apache/2.2.3 (Unix)
   Content-Type: httpd/unix-directory
   Client-Date: Wed, 14 Sep 2011 18:10:51 GMT
   Client-Peer: 127.0.0.1:2400
   Client-Response-Num: 1
   Client-Transfer-Encoding: chunked
   
   Hi! The local time is Wed Sep 14 11:10:51 2011.

The DefaultType doesn't help in this case because the content type has 
already been set by mod_dir.

So what's the right way to handle this? Something inside the PSGI handler that 
sets the content type to text/html if it was already set to a directory?

Re: [Mason] Dancer/Mason2/Apache Not memoized error

[Jonathan Swartz]

Ok. Sorry to hear about your back :(, hope you feel better.

I was thinking about making this change, which changes the default data dir to 
always be alongside the comp root. If you are able, can you apply this change 
to your version and see if it makes the default better under apache? (For some 
reason I'm not able to reproduce your bug on my system).

Also, clearly, I need to improve the error message when the object dir is not 
writable.

Thanks

 But my small investigation points towards the default value of data_dir being 
 the issue. When running Dancer in standalone mode data_dir correctly points 
 to 'data' in the application's root. But when running under apache it appears 
 towant 'data' to be in /usr/sbin - where, on Ubuntu, apache2 resides.
 
 So setting data_dir to something sensible fixes my problem.

Re: [Mason] Mason2 and utf8

[Jonathan Swartz]

Hi Jozef,

I'd like Mason to handle encoding intelligently, but since I don't regularly 
work with utf8, you and others will have to help me with the design.

This should probably be in a plugin, e.g. Mason::Plugin::UTF8.

Some have already thought about this on stackoverflow:

   http://stackoverflow.com/questions/5858596/how-to-make-mason2-utf8-clean

So for the things you particularly mention, something like this might work:

   package Mason::Plugin::UTF8;
   use Moose;
   with 'Mason::Plugin';
   1;

   package Mason::Plugin::UTF8::Request;
   use Mason::PluginRole;
   use Encode;

   # Encode all output in utf8 - ** only works with Mason 2.13 and beyond **
   #
   after 'process_output' = sub {
   my ($self, $outref) = @_;
   $$outref = encode_utf8( $$outref );
   };

   # Decode all parameters as utf8
   #
   around 'run' = sub {
   my $orig = shift;
   my $self = shift;
   
   my %params = @_;
   while (my ($key, $value) = each(%params)) {
   $value = decode_utf8($value);
   }
   $self-$orig(%params);
   }
   
   1;

It would probably be best if you or someone else knowledgable about utf8 issues 
created this plugin rather than myself. But let me know if there are things 
needed in the Mason core to make this easier.

Jon

Re: [Mason] Subclassing HTML::Mason::Request fails with unknown parameter 'ah' to constructor

[Jonathan Swartz]

Sorry, I don't know. I see that you copied that code directly out of the 
example in Subclassing.pod, but I've never tried to use it and can't say for 
sure if its behavior is still supported.

But presumably you should know whether your application are using ApacheHandler 
or CGIHandler, so it's probably unnecessary to try to alter the superclass 
dynamically.

 [Fri Jul 15 07:24:09 2011] [error] [client 172.16.189.1] The following 
 parameter was passed in the call to MyApp::Mason::Request-new() but was not 
 listed in the validation options: ah\n\nStack:\n  
 [/usr/share/perl5/HTML/Mason/ApacheHandler.pm:882]\n  
 [/usr/share/perl5/HTML/Mason/ApacheHandler.pm:822]\n  
 [/var/www/perl/MyApp/Mason.pm:41]\n  [-e:0]\n, referer: 
 http://fusion/index.html
 
 It seems that 'ah' is being passed in as an argument to the constructor of 
 the new class (MyApp::Mason::Request) but it is not being recognised by the 
 superclass.
 
 The new class (MyApp::Mason::Request) is very tiny / simple - at the moment 
 the only method that exists is 'new':
 
 sub new {
 
my $class = shift;
 
$class-alter_superclass(
$HTML::Mason::ApacheHandler::VERSION ?
'HTML::Mason::Request::ApacheHandler' :
$HTML::Mason::CGIHandler::VERSION ?
'HTML::Mason::Request::CGI' :
'HTML::Mason::Request' );
 
my $self = $class-SUPER::new( @_ );
 
return( $self );
 }
 
 httpd configuration is with a package:
 
 LocationMatch .*(\.html|\.pl|\.xml|\/)$
DefaultType text/html
SetHandler  perl-script
PerlHandler MyApp::Mason
 /LocationMatch
 
 And in the package MyApp::Mason there is
 
 my $apacheHandler = new HTML::Mason::ApacheHandler(
request_class = 'MyApp::Mason::Request',
 
 Everything kind of looks ok.
 
 Any help appreciated.

Re: [Mason] mason2: methods go vs visit

[Jonathan Swartz]

Ok. Can you actually post the full error message so I can see the stack? What 
version of Mason are you using? And can you run 't/Request.t' in the Mason 
distribution to see if it passes, since that tests visit()?

Thanks
Jon

Re: [Mason] Issues with HTMLFilters — Mason2 dies

Ok, thanks. I'll get right on this.

 Hi,
 
 after upgrading from Mason 2.07, HTMLFilters don't work anymore.
 
 Using % $foo | H % causes this error message:
 
 'ARRAY(0x107541e48)' is neither a code ref nor a filter object at 
 /opt/local/lib/perl5/site_perl/5.12.2/Mason/Request.pm line 353.
 
 It's also not possible to install the HTMLFilters plugin with the latest 
 Mason:

 Severity is critical, because it brakes Mason2 when using filters, which are 
 essential for 
 websites.
 
 I also filed a bug: #69038 — https://rt.cpan.org/Ticket/Display.html?id=69038

Re: [Mason] email on error

If you have a HTML::Mason::Exception object (which you should have if the error 
was thrown from inside Mason), you can call as_text or as_html on it. See 
HTML::Mason::Exceptions.

This was a parsing omission - $. does not work inside   tags. Will be fixed

Re: [Mason] Mason 2.0.6 - Plack session expiration

I think this is part of the psgi design, to have everything exposed to the app

[Mason] mason 2 file extensions

[Jonathan Swartz]

I want Mason 2 to have default file extensions that it facilitates and enforces 
(though they can be changed via parameters). Here's what I'm thinking of going 
with:

   .mc - top-level component
   
   A top-level component can serve as the page component in a request.
   
   .mi - internal component
   
   An internal component can only be accessed from other components.
   
   .mp - pure-perl component
   
   A pure-perl component contains only code; it is parsed as if its entire 
content
   was within a %class block. You do not need to (and are not allowed to) 
include
   Mason tags in this component, and it will not produce any output if called.

Originally I used .m for top-level component, but someone was kind enough to 
point out that this is used for Objective-C class files, which will become ever 
more widely used if Apple has its way. :)

I've checked all three of the above on http://www.fileinfo.com/ and they don't 
seem to have any strong associations.

Opinions welcome before this sets into stone!

Thanks
Jon
