Module: TemplateEngineFactory

Recommended Posts

Nevermind.  Rookie mistake.  I just needed to check if the post.template == "calendar-posting" before trying to access post.event_description.

@gmclelland

Twig sometimes has problems when you try to access a property via magic getter. I consistently use $page->get('my_field') to avoid this issue. So in your example, you could use {{ post.get('event_description') }}.

Thanks @Wanze, I haven't ran into any issues so far, but that's good to know.  The only thing I'm currently stuck on right now is trying to figure out how to get the TwigExtensions module to work with the latest versions of TemplateEngineTwig.  It was working previously before TemplateEngineTwig 1.1.0.  Any help testing is appreciated.

Are you using TwigExtensions library at all in your projects?  If not, don't you need the date functions and text truncating functions?

After I get my sites upgraded to the latest version of TemplateEngineFactory and TemplateEngineTwig, I can start checking into a possible bug I think I see with the new changes to handle Wire404Exception.

Side note:  I really appreciate the work you've done on this module.  To me it is so much cleaner looking at Twig code than looking at a php mixed with html.   I like that in Processwire, I can simply build up my variables in the template to be sent to the view.  That way my views(Twig files) are very simple and contain simple logic only.

Hi @Sipho

Sorry I missed your post. I don't know/use markup regions myself, so it's hard for me to help. Does your code work if you disable the TemplateEngineFactory module? If it works, then somehow markup regions are not respected when your ProcessWire templates are getting rendered by this module. I try to look into this at the end of this week.

Cheers

@Wanze It does work when I disable TemplateEngineFactory (and move my home.php file back into templates/).

I don't really know how ProcessWire renders templates under the hood but it could be that it only renders markup regions of files under templates/.

I would greatly appreciate it if you could take a look at it. You can take a look at this tutorial to get started using markup regions.

Hi @Wanze

I don't know if it's possible in the current state of the module to disable "Global File Template" for a given template file.

I needed this feature in order to work with a REST API endpoint. The problem is when I try to get JSON data from http://my.sites.sek/api, the markup of the global template file is sent.

 

I forked your module and added an option to ignore the global template file on given template. If it make sense, I can send a pull request.

Hi @Sipho

MarkupRegions is currently only processed during Page::render(). TemplateEngineProcessWire uses TemplateFile::render() to return the markup, where MarkupRegions are not recognized/populated.

Here are the relevant lines: https://github.com/processwire/processwire/blob/master/wire/modules/PageRender.module#L521-L526

It should be possible to integrate this logic into TemplateFile::render via hooks. Unfortunately I do not have much time for ProcessWire these days 😕
I'm happy to accept a pull request though :)

Cheers

Hello @Wanse and all of you,

This plugin is a must, thank you Wanse.

For 2 days I have been searching, I guess I have a pattern problem with my twig templates.

  1. My global template is base.twig
  2. Inside I have {% block home %}{% endblock %} and several includes parts.
  3. Nothing from this block is displayed. It works only if I keep my global template file field empty.
  4. In my home.twig I have
{% extends 'base.twig' %}
{% block home %}
<div id="corps"> <div id="titres">
<div id="titre">{{ page.title }}</div>
</div>
 <div class="hr"></div>
<br>
{% block engagement %}{% endblock %}
{% endblock %}

What do you think ?

In my base.twix I have all my html code...

Thank you

Hello @Sten So what exactly is the problem? Don't you get any output? What happens? What is you path to templates in the config of the module? I have /templates/views and with my twig files in this directory everything works fine. Did you choose twig as the template files suffix?
Your code and extend seem to be correct.
The global template file field has to be empty so you can work with extends like you do

@Sten

Your twig templates look fine, the problem is the global template file setting. Just leave that config empty. This is a "global setting" of the TemplateEngineFactory which is supported by all engines, but actually makes no sense in Twig and generally in engines supporting template inheritance. It was introduced by a feature request, but now I think it's more confusing than useful.

Cheers

Hello Jmartsch and Wanze,

It is great to be assisted, thank you 😊. I changed my config to have the global file field empty. So I put all my *.twig files in the views directory. I created partials directory for parts included in base.twig.
So I keep home.twig and engagement.twig in views.

in home.twig I have
 

{% block home %}
<div id="corps"> <div id="titres">
<div id="titre">{{ page.title }}</div>
</div>
 <div class="hr"></div>
<br>
{% block engagement %}{% endblock %}
{% endblock %}

In engagement.twig, I have
 

{% extends 'home.twig' %}
{% block engagement %}
<p>His cognitis Gallus ut serpens adpetitus telo vel saxo iamque spes extremas opperiens et succurrens saluti suae quavis ratione colligi omnes iussit armatos et cum starent attoniti, districta dentium acie stridens adeste inquit viri fortes mihi periclitanti vobiscum.</p>
<p>Mensarum enim voragines et varias voluptatum inlecebras, ne longius progrediar, praetermitto illuc transiturus quod quidam per ampla spatia urbis subversasque silices sine periculi metu properantes equos velut publicos signatis quod dicitur calceis agitant, familiarium agmina tamquam praedatorios globos post terga trahentes ne Sannione quidem, ut ait comicus, domi relicto. quos imitatae matronae complures opertis capitibus et basternis per latera civitatis cuncta discurrunt.</p>
{% endblock %}

But still engagement block is not displayed.

@Sten In home.twig, the block engagement block is nested inside the home block. In engagement.twig, this is not the case. Does it work if you either move it out of the home block in your parent template; or recreate the nested block structure in engagement.twig.

Hello,

I'm trying out TemplateEnginePug, and I get a blank page. I have a empty home.php and a views/home.pug. This one has a very basic paragraph. Still I get a blank page, without any error. Same with TemplateEngineJade. Can't manage to see a byte on screen no matter what.

Tested other template languages (twig, processwire, latte), and it works fine. Config debug is `true`.

Thanks!

Hey @Manaus 

I updated the Pug Engine to work with the latest version, it should work now again, please try!

Hi folks!

I just released a new major (2.x) version of the module. Important things first: This version includes backwards compatibility breaks. At the moment, only Twig and the bundled ProcessWire engine work with the 2.0 version. I will now contact maintainers that implemented other engines (Pug, Jade etc.) and ask them to release a 2.x version as well. The 1.x version of the module is still available on the 1.x branch and continues to exist.

So why a version 2.x? Basically it's the same concept, but done in the right way. 😉

  • The rendering via template engine is now integrated correctly into Page::render(). You can call the render() method on any page, and the module will render it via template engine. In version 1.x, this is only true for the current page.
  • Automatic page rendering is now optional, you can use the module to only integrate a template engine, without hooking into Page::render at all.
  • There are settings to enable/disable the automatic page rendering for templates. Because there might be templates where Page::render should not be replaced.
  • The module provides hooks to customize it for your needs.
  • I wrote a bunch of unit tests and use Travis for CI. Problems like "the 404 page is not displayed if a Wire404Exception is thrown in a controller" are now tested properly.

I am writing a documentation on everything, you can read it here: https://github.com/wanze/TemplateEngineFactory/blob/master/DOCUMENTATION.md

One important part is how to update from 1.x to 2.x. Depending on the feature usage of the module, this might involve some manual update steps, because the public API changed. If you try to update, please let me know about any issues you are encountering, so that we can add them to the documentation. Don't worry, you do not have to update, as the 1.x version continues to exist. For a new project, definitely start with 2.x!

Last but not least, modules providing template engines must be updated too, but this should be quite easy. For Twig, I decided to support installations only via Composer, and I think that this should be the way to go for the other modules. 3rd party dependencies must be manageable in a reliable way, and Composer is the right tool for this job.

Cheers

Nice! will you upgrade TemplateEngineSmarty also soon?

Actually I wanted to ask you if you would like to develop the 2.x version of TemplateEngineSmarty, and if you like, maintain the project? The implementation itself is really easy, you can basically copy + past from Twig and tweak/change things for Smarty. I only use Twig these days, so I might miss some useful/important stuff for Smarty. What do you think? 😄

Sure we can do that 🙂 Do you want to transfer the repo to our account: https://github.com/blue-tomato ?

You can write me also via email for the details: markus.tiefenbacher {at} blue-tomato.com

      Happy new year, everybody 🥬
      I've been sitting on this Dashboard module I made for a client and finally came around to cleaning it up and releasing it to the wider public. This is how it looks.
      ProcessWire Dashboard

      If anyone is interested in trying this out, please go ahead! I'd love to get some feedback on it. If this proves useful and survives some real-world testing, I'll add this to the module directory.
      Download
      You can find the latest release on Github.
      Documentation
      Check out the documentation to get started. This is where you'll find information about included panel types and configuration options.
      Custom Panels
      My goal was to make it really simple to create custom panels. The easiest way to do that is to use the panel type template and have it render a file in your templates folder. This might be enough for 80% of all use cases. For anything more complex (FormBuilder submissions? Comments? Live chat?), you can add new panel types by creating modules that extend the DashboardPanel base class. Check out the documentation on custom panels or take a look at the HelloWorld panel to get started. I'm happy to merge any user-created modules into the main repo if they might be useful to more than a few people.
       Disclaimer
      This is a pre-release version. Please treat it as such — don't install it on production sites. Just making sure 🍇
      Roadmap
      These are the things I'm looking to implement myself at some point. The wishlist is a lot longer, but those are the 80/20 items that I probably won't regret spending time on.
      Improve documentation & add examples ⚙️ Panel types Google Analytics ⚙️ Add new page  🔥 Drafts 🔥 At a glance / Page counter 404s  Layout options Render multiple tabs per panel panel groups with heading and spacing between ✅ panel wrappers as grid item (e.g. stacked notices) ✅ Admin themes support AdminThemeReno and AdminThemeDefault ✅ Shortcuts panel add a table layout with icon, title & summary ✅ Chart panel add default styles for common chart types ✅ load chart data from JS file (currently passed as PHP array) Collection panel support image columns ✅ add buttons: view all & add new ✅

      This module is inspired by and similar to the Template Stubs module. The author of that module has not been active in the PW community for several years now and parts of the code for that module didn't make sense to me, so I decided to create my own module. Auto Template Stubs has only been tested with PhpStorm because that is the IDE that I use.
      Auto Template Stubs
      Automatically creates stub files for templates when fields or fieldgroups are saved.
      Stub files are useful if you are using an IDE (e.g. PhpStorm) that provides code assistance - the stub files let the IDE know what fields exist in each template and what data type each field returns. Depending on your IDE's features you get benefits such as code completion for field names as you type, type inference, inspection, documentation, etc.
      Installation
      Install the Auto Template Stubs module.
      Configuration
      You can change the class name prefix setting in the module config if you like. It's good to use a class name prefix because it reduces the chance that the class name will clash with an existing class name.
      The directory path used to store the stub files is configurable.
      There is a checkbox to manually trigger the regeneration of all stub files if needed.
      Usage
      Add a line near the top of each of your template files to tell your IDE what stub class name to associate with the $page variable within the template file. For example, with the default class name prefix you would add the following line at the top of the home.php template file:
      /** @var tpl_home $page */ Now enjoy code completion, etc, in your IDE.

      Adding data types for non-core Fieldtype modules
      The module includes the data types returned by all the core Fieldtype modules. If you want to add data types returned by one or more non-core Fieldtype modules then you can hook the AutoTemplateStubs::getReturnTypes() method. For example, in /site/ready.php:
      // Add data types for some non-core Fieldtype modules $wire->addHookAfter('AutoTemplateStubs::getReturnTypes', function(HookEvent $event) { $extra_types = [ 'FieldtypeDecimal' => 'string', 'FieldtypeLeafletMapMarker' => 'LeafletMapMarker', 'FieldtypeRepeaterMatrix' => 'RepeaterMatrixPageArray', 'FieldtypeTable' => 'TableRows', ]; $event->return = $event->return + $extra_types; }); Credits
      Inspired by and much credit to the Template Stubs module by mindplay.dk.

      Jumplinks for ProcessWire
      Release: 1.5.60
      Composer: rockett/jumplinks
      ⚠️ NOTICE: 1.5.60 is an important security patch-release for an XSS vulnerability discovered by @phlp. It's HIGHLY RECOMMENDED that all Jumplinks users update to the latest version as soon as possible.
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy! 🙂
