HannaCodeDialog

Recommended Posts

I have had this module sitting in a 95% complete state for a while now and have finally made the push to get it out there. Thanks to @teppo for his Hanna Code Helper module which I referred to and borrowed from during development.

HannaCodeDialog

A module for ProcessWire CMS/CMF. Provides a number of enhancements for working with Hanna Code tags in CKEditor. The main enhancement is that Hanna tags in a CKEditor field may be double-clicked to edit their attributes using core ProcessWire inputfields in a modal dialog.

Requires the Hanna Code module.

Installation

Install the HannaCodeDialog module using any of the normal methods.

For any CKEditor field where you want the "Insert Hanna tag" dropdown menu to appear in the CKEditor toolbar, visit the field settings and add "HannaDropdown" to the "CKEditor Toolbar" settings field.

Module configuration

Visit the module configuration screen to set any of the following:

  • Exclude prefix: Hanna tags named with this prefix will not appear in the CKEditor toolbar dropdown menu for Hanna tag insertion.
  • Exclude Hanna tags: Hanna tags selected here will not appear in the CKEditor toolbar dropdown menu for Hanna tag insertion.
  • Background colour of tag widgets: you can customise the background colour used for Hanna tags in CKEditor if you like.
  • Dialog width: in pixels
  • Dialog height: in pixels

Features

Insert tag from toolbar dropdown menu

Place the cursor in the CKEditor window where you want to insert your Hanna tag, then select the tag from the "Insert Hanna tag" dropdown.

'Insert Hanna tag' dropdown

Advanced: if you want to control which tags appear in the dropdown on particular pages or templates you can hook HannaCodeDialog::getDropdownTags. See the forum support thread for examples .

Edit tag attributes in modal dialog

Insert a tag using the dropdown or double-click an existing tag in the CKEditor window to edit the tag attributes in a modal dialog.

Modal dialog

Tags are widgets

Hanna tags that have been inserted in a CKEditor window are "widgets" - they have a background colour for easy identification, are protected from accidental editing, and can be moved within the text by drag-and-drop.

![Hanna tag widget]hcd-widget

Options for tag attributes may be defined

You can define options for a tag attribute so that editors must choose an option rather than type text. This is useful for when only certain strings are valid for an attribute and also has the benefit of avoiding typos.

Add a new attribute for the Hanna tag, named the same as the existing attribute you want to add options for, followed by "__options". The options themselves are defined as a string, using a pipe character as a delimiter between options. Example for an existing attribute named "vegetables":

vegetables__options=Spinach|Pumpkin|Celery|Tomato|Brussels Sprout|Potato

You can define a default for an attribute as normal. Use a pipe delimiter if defining multiple options as the default, for example:

vegetables=Tomato|Potato

Dynamic options

Besides defining static options as above, you can use one Hanna tag to dynamically generate options for another. For instance, you could create a Hanna tag that generates options based on images that have been uploaded to the page, or the titles of children of the page.

Your Hanna tag that generates the options should echo a string of options delimited by pipe characters (i.e. the same format as a static options string).

You will probably want to name the Hanna tag that generates the options so that it starts with an underscore (or whatever prefix you have configured as the "exclude" prefix in the module config), to avoid it appearing as an insertable tag in the HannaCodeDialog dropdown menu.

Example for an existing attribute named "image":

image__options=[[_images_on_page]]

And the code for the _images_on_page tag:

<?php
$image_names = array();
$image_fields = $page->fields->find('type=FieldtypeImage')->explode('name');
foreach($image_fields as $image_field) {
    $image_names = array_unique( array_merge($image_names, $page->$image_field->explode('name') ) );
}
echo implode('|', $image_names);

Advanced: define or manipulate options in a hook

You can hook HannaCodeDialog::prepareOptions to define or manipulate options for a Hanna tag attribute. Your Hanna tag must include a someattribute__options attribute in order for the hook to fire. The prepareOptions method receives the following arguments that can be used in your hook:

  • options_string Any existing string of options you have set for the attribute
  • attribute_name The name of the attribute the options are for
  • tag_name The name of the Hanna tag
  • page The page being edited

If you hook after HannaCodeDialog::prepareOptions then your hook should set $event->return to an array of option values, or an associative array in the form of $value => $label.

Choice of inputfield for attribute

You can choose the inputfield that is used for an attribute in the dialog.

For text attributes the supported inputfields are text (this is the default inputfield for text attributes so it isn't necessary to specify it if you want it) and textarea. Note: any manual line breaks inside a textarea are removed because these will break the CKEditor tag widget.

Inputfields that support the selection of a single option are select (this is the default inputfield for attributes with options so it isn't necessary to specify it if you want it) and radios.

Inputfields that support the selection of multiple options are selectmultiple, asmselect and checkboxes.

You can also specify a checkbox inputfield - this is not for attributes with defined options but will limit an attribute to an integer value of 1 or 0.

The names of the inputfield types are case-insensitive.

Example for an existing attribute named "vegetables":

vegetables__type=asmselect

Descriptions and notes for inputfields

You can add a description or notes to an attribute and these will be displayed in the dialog.

Example for an existing attribute named "vegetables":

vegetables__description=Please select vegetables for your soup.
vegetables__notes=Pumpkin and celery is a delicious combination.

Notes

When creating or editing a Hanna tag you can view a basic cheatsheet outlining the HannaCodeDialog features relating to attributes below the "Attributes" config inputfield.

Troubleshooting

HannaCodeDialog includes and automatically loads the third-party CKEditor plugins Line Utilities and Widget. If you have added these plugins to your CKEditor field already for some purpose and experience problems with HannaCodeDialog try deactivating those plugins from the CKEditor field settings.

Great thing @Robin S! Something to make content creation even easier.

I see there is an option to exclude some Hanna codes from the list. What do you think about a whitelist option (preferably overridden on a template basis)?

In v0.0.2 I have added a hookable method that supplies the array of tag names for the dropdown menu. You can use an 'after' hook to control what appears in the dropdown. A couple of examples...

Define the tags for a given template:

$this->addHookAfter('HannaCodeDialog::getDropdownTags', function($event) {
    $page = $event->arguments('page');
    // Show only these tags on pages using the 'basic_page' template
    if($page->template == 'basic_page') {
        $event->return = ['some_tag', 'another_tag'];
    }
});

Remove certain tags for a given template:

$this->addHookAfter('HannaCodeDialog::getDropdownTags', function($event) {
    $page = $event->arguments('page');
    $tags = $event->return;
    // Remove these tags on pages using the 'basic_page' template
    if($page->template == 'basic_page') {
        $filtered_tags = array_filter($tags, function($tag) {
            return !in_array($tag, ['some_tag', 'another_tag']);
        });
        $event->return = array_values($filtered_tags);
    }
});

it's working well so far... the only error i encountered was because the hanna code module config may not even be populated if you install hanna code and use the defaults, and never actually save the module, so one option would be to also check if the index for that module config is set, (around like 150 of the module)...

Thanks for the report @Macrura, fixed with isset() now (no version change).

It bugs me a bit that PW doesn't save default values to the module config automatically in the module installation routine. Seems to me that is the whole point of defining a default - so some config value is present if nothing has been set manually.

it's a really amazing module, and will be indispensable for any site using hanna codes, i can already see this solving major problems with users entering incorrect stuff into their hanna codes. the options and description stuff is also amazing work!

Thank you, @Robin S, for this nice module. But I'm not sure I can use it for my special case.

To let my editor user embed a video from a internal page into a textarea (CKE), he would insert a HannaCode like this:

[[video source='LINK']]

Here the editor has to doubleclick the string LINK to select it, and click the "Link" Button of the CKE. The modal window "Insert Link" opens, and the user just needs to click "Select Page" to choose the page containing the wanted video in a field of type File. The HannaCode "video" itself would wrap the file data with the necessary code provided by the videoplayer script in use. This all works fine - even if I admit it's not very elegant.

After installing the HannaCodeDialog module, the string LINK appeares in the input field "source" of the dialog, of course. But there it's not possible to evoke the Insert Link action of the CKE. (And if there exist already some other calls of this HannaCode in the CKE-textarea, they also would become the functinoality of the module, and those LINKs were not editable anymore, too.)

So I ended in uninstalling the module. May be this could be solved by using some dynamic options - I didn't dive into these yet.

And of course, very likely my way to use HannaCode at all is a bit stupid, anyway...

@ottogal, you are right - this module will not cover your way of using HannaCode.

But if you only needed to select from videos uploaded to the current page instead of letting the editor choose another page (or alternatively from one page that contains all videos), you could adapt the approach I show in the first post for creating select options from images on the page.

Yes, I considered this. But indeed each video has to be fetched from it's own page (child of one page "video pool")...  ???

If you have a "one video per page" setup then again you could dynamically generate options using another Hanna tag: get all children of "video pool" that have a video uploaded to them.

If people come up with any nifty usages of HannaCodeDialog it would be cool to get a bit of a library going in this thread.

Here's one to get the ball rolling.

Select FormBuilder form

For the foolproof selecting of a FormBuilder form to embed in a CKEditor field.

Import both of the export strings to use this. The code is shown here just for reference.

_formbuilder_forms

Export string (import this into Hanna Code):

!HannaCode:_formbuilder_forms:eyJuYW1lIjoiX2Zvcm1idWlsZGVyX2Zvcm1zIiwidHlwZSI6IjIiLCJjb2RlIjoiPD9waHBcbmVjaG8gaW1wbG9kZSgnfCcsIGl0ZXJhdG9yX3RvX2FycmF5KCRmb3Jtcy0+Z2V0SXRlcmF0b3IoKSkpOyJ9/!HannaCode

Code (just for reference):

<?php
echo implode('|', iterator_to_array($forms->getIterator()));

select_form

Export string (import this into Hanna Code):

!HannaCode:select_form:eyJuYW1lIjoic2VsZWN0X2Zvcm0iLCJ0eXBlIjoiMiIsImNvZGUiOiJcLypoY19hdHRyXG5mb3JtPVwiXCJcbmZvcm1fX29wdGlvbnM9XCJbW19mb3JtYnVpbGRlcl9mb3Jtc11dXCJcbmhjX2F0dHIqXC9cbjw/cGhwXG5pZigkZm9ybSkgZWNobyBcIjxwPmZvcm0tYnVpbGRlclwvJGZvcm08XC9wPlwiOyJ9/!HannaCode

Code (just for reference):

<?php
if($form) echo "<p>form-builder/$form</p>";

This module is just what I was looking for!

I'm using it to create links to a file download page, instead of to the file itself, with the 'dynamic options' method.

However, although it works perfectly, I'm getting a strange error in the Hanna dialogue modal window (see screenshot):

processwire_HannaCodeDialogue_error.png.4c1d8c79cfa35f04998895544cb16935.png

I have tried deleting the file compiler cache, but it did not resolve the issue.

Set-up Info:

  • Hanna Code: ver. 0.2.0
  • HannaCode Dialogue: ver. 0.0.3
  • ProcessWire: ver. 3.0.58
  • PHP: ver.  5.6.21

Thanks for the report. Are you running PHP 7.1? I think that's the version that started enforcing stricter numeric values and throwing errors like this.

I tested in PHP7.1 and I can't reproduce this issue. Also, I can't see how this error could be connected to HannaCodeDialog. From what I've read the "non well formed numeric value" error occurs when some arithmetic or other operation that expects an integer receives a string instead. And line 118 of Database.php is:

$timerTotalSinceStart = Debug::timer() - $timerFirstStartTime;

So probably Debug::timer() or $timerFirstStartTime is not an integer, but this is core code that relates to the debug mode tools and HannaCodeDialog has nothing to do with that.

Do you see the error as soon as you install HannaCodeDialog? Do you see it if you have no Hanna codes defined when the module is installed (I'm wondering if the problem is with one of your Hanna codes rather than the module itself)? If you uninstall HannaCodeDialog does the error go away?

Can I activate the Toolbar in CKEditor without choosing the Hanna Code Textformater and use the $hanna->render() API?

I will support this in the next version. The intention was to avoid needlessly attaching the plugins to every instance of CKEditor if the textformatter wasn't applied to that field, but I guess to support $hanna->render() there's no way to know if a CKEditor field needs the plugins or not.

I'm having trouble understanding exactly what's going wrong for you here. Make sure you meet the prerequisites and have completed the installation process:

  • TextformatterHannaCode must be installed.
  • TextformatterHannaCode must be applied as a textformatter to your CKEditor field.
  • You must have at least one Hanna code created.
  • Install HannaCodeDialog module.
  • Edit the settings for your CKEditor field and in "Input > CKEditor Settings > CKEditor Toolbar" add "HannaDropdown" (to be precise, with a comma space separating it from the other items there)

v0.0.5 released. Allows use of the dropdown/dialog in CKEditor fields that do not have the Hanna Code textformatter applied to them, in order to support $hanna->render() usage.

I haven't tried this module so this request may be out of sync but how about adding items that wouldn't require Hanna code module? What I have in mind is having eg a

$config->hannaCodeDialogItems = array( item1 => function () { ... }, ... )

code somewhere in template files so one could easily insert custom items to ckeditor? Perhaps $config could be replaced with $page.

      First a note about my other modules...
      I have three existing modules that are similar in that they allow restrictions to be placed on repeating inputfields: Limit Repeater, Limit PageTable, Limit Table
      Restrict Repeater Matrix takes a different approach to the module configuration from those other modules. The module settings for Restrict Repeater Matrix are applied in the field settings rather in a module config screen. I think this new approach is better, but it means that it isn't practical to create different settings for different roles via the admin interface. Instead the module has a hookable method, allowing roles to be targeted and other advanced usages to be achieved via a hook. The result is that the module is more flexible.
      I intend to transition my other modules to the same approach over the coming weeks, but because this will result in breaking changes I will be releasing the updated modules under new names ("Restrict Repeater", etc) to avoid users upgrading via the Upgrades module without full awareness of the changes. The old modules will be marked as deprecated.
      Restrict Repeater Matrix
      A module for ProcessWire CMS/CMF. Allows restrictions and limits to be placed on Repeater Matrix fields. Requires ProcessWire >= v3.0.0 and FieldtypeRepeaterMatrix >= v0.0.5.
      For any matrix type in a Repeater Matrix field you have the option to:
      Disable settings for items (cannot change matrix type) Prevent drag-sorting of items Prevent cloning of items Prevent toggling of the published state of items Prevent trashing of items Limit the number of items that may be added to the inputfield. When the limit is reached the "Add new" button for the matrix type will be removed and the matrix type will not be available for selection in the "Type" dropdown of other matrix items. Please note that restrictions and limits are applied with CSS/JS so should not be considered tamper-proof.
      Usage
      Install the Restrict Repeater Matrix module.
      For each matrix type created in the Repeater Matrix field settings, a "Restrictions" fieldset is added at the bottom of the matrix type settings:

      For newly added matrix types, the settings must be saved first in order for the Restrictions fieldset to appear. Set restrictions for each matrix type as needed. A limit of zero means that no items of that matrix type may be added to the inputfield.
      Setting restrictions via a hook
      Besides setting restrictions in the field settings, you can also apply or modify restrictions by hookingRestrictRepeaterMatrix::checkRestrictions. This allows for more focused restrictions, for example, applying restrictions depending on the template of the page being edited or depending on the role of the user.
      The checkRestrictions() method receives the following arguments:
      $field This Repeater Matrix field $inputfield This Repeater Matrix inputfield $matrix_types An array of matrix types for this field. Each key is the matrix type name and the value is the matrix type integer. $page The page that is open in ProcessPageEdit The method returns a multi-dimensional array of matrix types and restrictions for each of those types. An example of a returned array:

      Example hooks
      Prevent the matrix type "images_block" from being added to "my_matrix_field" in a page with the "basic-page" template:
      $wire->addHookAfter('RestrictRepeaterMatrix::checkRestrictions', function(HookEvent $event) { $field = $event->arguments('field'); $page = $event->arguments('page'); $type_restrictions = $event->return; if($field->name === 'my_matrix_field' && $page->template->name === 'basic-page') { $type_restrictions['images_block']['limit'] = 0; } $event->return = $type_restrictions; }); Prevent non-superusers from trashing any Repeater Matrix items in "my_matrix_field":
      $wire->addHookAfter('RestrictRepeaterMatrix::checkRestrictions', function(HookEvent $event) { $field = $event->arguments('field'); $type_restrictions = $event->return; if($field->name === 'my_matrix_field' && !$this->user->isSuperuser()) { foreach($type_restrictions as $key => $value) { $type_restrictions[$key]['notrash'] = true; } } $event->return = $type_restrictions; }); http://modules.processwire.com/modules/restrict-repeater-matrix/

      Here's a little text formatter module that redirects all external links found in a textarea (e.g. for hit counting) to a given URL.
      TextformatterExternalRedirect
      GitHub repo
      As TextFormatters do, this module modifies the contents of the textarea (HTML) at rendering time. It prepends the given URL to the link address for external links (http and https), optionally makes sure that the link is opened in a new window and allows you to add css classes to such links.
      All options can be configured in the module's configuration settings.
      Usage:
      Download the zip archive and extract it to site/modules, the rename the top folder to TextformatterExternalRedirect Go to the backend and select "Modules" -> "Refresh", then click "Install" for "External Link Redirect" Click "Settings" and configure the module
      Go into the field configuration for the field(s) you want this formatter to apply to and add it from the dropdown
      Done, now any external links in the configured fields will have the configured settings applied Feel free to leave feedback and post and questions you have here.

      Hey folks!
      Took a couple of late nights, but managed to turn this old gist of mine into a proper module. The name is SearchEngine, and currently it provides support for indexing page contents (into a hidden textarea field created automatically), and also includes a helper feature ("Finder") for querying said contents. No fancy features like stemming here yet, but something along those lines might be added later if it seems useful (and if I find a decent implementation to integrate).
      Though the API and selector engine make it really easy to create site search pages, I pretty much always end up duplicating the same features from site to site. Also – since it takes a bit of extra time – it's tempting to skip over some accessibility related things, and leave features like text highlighting out. Overall I think it makes sense to bundle all that into a module, which can then be reused over and over again 🙂
      Note: markup generation is not yet built into the module, which is why the examples below use PageArray::render() method to produce a simple list of results. This will be added later on, as a part of the same module or a separate Markup module. There's also no fancy JS API or anything like that (yet).
      This is an early release, so be kind – I got the find feature working last night (or perhaps this morning), and some final tweaks and updates were made just an hour ago 😅
      GitHub repository: https://github.com/teppokoivula/SearchEngine Modules directory: https://modules.processwire.com/modules/search-engine/ Demo: https://wireframe-framework.com/search/ Usage
      Install SearchEngine module. Note: the module will automatically create an index field install time, so be sure to define a custom field (via site config) before installation if you don't want it to be called "search_index". You can change the field name later as well, but you'll have to update the "index_field" option in site config or module settings (in Admin) after renaming it.
      Add the site search index field to templates you want to make searchable. Use selectors to query values in site search index. Note: you can use any operator for your selectors, you will likely find the '=' and '%=' operators most useful here. You can read more about selector operators from ProcessWire's documentation.
      Options
      By default the module will create a search index field called 'search_index' and store values from Page fields title, headline, summary, and body to said index field when a page is saved. You can modify this behaviour (field name and/or indexed page fields) either via the Module config screen in the PocessWire Admin, or by defining $config->SearchEngine array in your site config file or other applicable location:
      $config->SearchEngine = [ 'index_field' => 'search_index', 'indexed_fields' => [ 'title', 'headline', 'summary', 'body', ], 'prefixes' => [ 'link' => 'link:', ], 'find_args' => [ 'limit' => 25, 'sort' => 'sort', 'operator' => '%=', 'query_param' => null, 'selector_extra' => '', ], ]; You can access the search index field just like any other ProcessWire field with selectors:
      if ($q = $sanitizer->selectorValue($input->get->q)) { $results = $pages->find('search_index%=' . $query_string . ', limit=25'); echo $results->render(); echo $results->renderPager(); } Alternatively you can delegate the find operation to the SearchEngine module as well:
      $query = $modules->get('SearchEngine')->find($input->get->q); echo $query->resultsString; // alias for $query->results->render() echo $query->pager; // alias for $query->results->renderPager() Requirements
      ProcessWire >= 3.0.112 PHP >= 7.1.0 Note: later versions of the module may require Composer, or alternatively some additional features may require installing via Composer. This is still under consideration – so far there's nothing here that would really depend on it, but advanced features like stemming most likely would.
      Installing
      It's the usual thing: download or clone the SearchEngine directory into your /site/modules/ directory and install via Admin. Alternatively you can install SearchEngine with Composer by executing composer require teppokoivula/search-engine in your site directory.

      MarkupMenu is a markup module for generating menu trees. When provided a root page as a starting point, it generates a navigation tree (by default as a HTML "<ul>" element wrapped by a "<nav>" element) from that point onwards. If you've also provided it with current (active) page, the menu will be rendered accordingly, with current item highlighted and items rendered up to that item and its children (unless you disable the "collapsed" option, in which case the full page tree will be rendered instead).
      Modules directory: https://modules.processwire.com/modules/markup-menu/ GitHub repository: https://github.com/teppokoivula/MarkupMenu Usage
      As a markup module, MarkupMenu is intended for front-end use, but you can of course use it in a module as well. Typically you'll only need the render() method, which takes an array of options as its only argument:
      echo $modules->get('MarkupMenu')->render([ 'root_page' => $pages->get(1), 'current_page' => $page, ]); Note: if you omit root_page, site root page is used by default. If you omit current_page, the menu will be rendered, but current (active) page won't be highlighted etc.
      A slightly more complex example, based on what I'm using on one of my own sites to render a (single-level) top menu:
      echo $modules->get('MarkupMenu')->render([ 'current_page' => $page, 'templates' => [ 'nav' => '<nav class="{classes} menu--{menu_class_modifier}" aria-label="{aria_label}">%s</nav>', 'item_current' => '<a class="menu__item menu__item--current" href="{item.url}" tabindex="0" aria-label="Current page: {item.title}">{item.title}</a>', ], 'placeholders' => [ 'menu_class_modifier' => 'top', 'aria_label' => 'Main navigation', ], 'include' => [ 'root_page' => true, ], 'exclude' => [ 'level_greater_than' => 1, ], ]); Note: some things you see above may not be entirely sensible, such as the use of {menu_class_modifier} and {aria_label} placeholders. On the actual site the "nav" template is defined in site config, so I can define just these parts on a case-by-case basis while actual nav markup is maintained in one place.
      Please check out the README file for available render options. I'd very much prefer not to keep this list up to date in multiple places. Basically there are settings for defining "templates" for different parts of the menu (list, item, etc.), include array for defining rules for including in the menu and exclude array for the opposite effect, classes and placeholders arrays for overriding default classes and injecting custom placeholders, etc. 🙂
      MarkupMenu vs. MarkupSimpleNavigation
      TL;DR: this is another take on the same concept. There are many similarities, but also some differences – especially when it comes to the supported options and syntax. If you're currently using MarkupSimpleNavigation then there's probably no reason to switch over.
      I'd be surprised if someone didn't draw lines between this module and Soma's awesome MarkupSimpleNavigation. Simply put I've been using MSN (...) for years, and it's been great – but there are some issues with it, particularly in the markup generation area, and it also does some things in a way that doesn't quite work for me – the xtemplates thing being one of these. In some ways less about features, and more about style, I guess 🙂
      Anyhow, in MarkupMenu I've tried to correct those little hiccups, modernise the default markup, and allow for more flexibility with placeholder variables and additional / different options. MarkupMenu was built for ProcessWire 3.0.112+ and with PHP 7.1+ in mind, it's installable with Composer, and I have a few additional ideas (such as conditional placeholders) still on my todo list.
      One more small(ish) difference is that MarkupMenu supports overriding default options via $config->MarkupMenu. I find myself redefining the default markup for every site, which until now meant that each site had a wrapper function for MarkupSimpleNavigation (to avoid code / config repetition), and this way I've been able to leave that out 🙂
      Requirements
      ProcessWire >= 3.0.112 PHP >= 7.1.0 If you're working on an earlier version of ProcessWire or PHP, use MarkupSimpleNavigation instead.

      Hey folks!
      I'm happy to finally introduce a project I've been working on for quite a while now: it's called Wireframe, and it is an output framework for ProcessWire.
      Note that I'm posting this in the module development area, maily because this project is still in rather early stage. I've built a couple of sites with it myself, and parts of the codebase have been powering some pretty big and complex sites for many years now, but this should still be considered a soft launch 🙂
      --
      Long story short, Wireframe is a module that provides the "backbone" for building sites (and apps) with ProcessWire using an MVC (or perhaps MVVM – one of those three or four letter abbreviations anyway) inspired methodology. You could say that it's an output strategy, but I prefer the term "output framework" since in my mind the word "strategy" means something less tangible. A way of doing things, rather than a tool that actually does things.
      Wireframe (the module) provides a basic implementation for some familiar MVC concepts, such as Controllers and a View layer – the latter of which consists of layouts, partials, and template-specific views. There's no "model" layer, since in this context ProcessWire is the model. As a module Wireframe is actually quite simple – not even nearly the biggest one I've built – but there's still quite a bit of stuff to "get", so I've put together a demo & documentation site for it at https://wireframe-framework.com/.
      In addition to the core module, I'm also working on a couple of site profiles based on it. My current idea is actually to keep the module very light-weight, and implement most of the "opinionated" stuff in site profiles and/or companion modules. For an example MarkupMenu (which I released a while ago) was developed as one of those "companion modules" when I needed a menu module to use on the site profiles.
      Currently there are two public site profiles based on Wireframe:
      site-wireframe-docs is the demo&docs site mentioned above, just with placeholder content replaced with placeholder content. It's not a particularly complex site, but I believe it's still a pretty nice way to dig into the Wireframe module. site-wireframe-boilerplate is a boilerplate (or starter) site profile based on the docs site. This is still very much a work in progress, but essentially I'm trying to build a flexible yet full-featured starter profile you can just grab and start building upon. There will be a proper build process for resources, it will include most of the basic features one tends to need from site to site, etc. --
      Requirements and getting started:
      Wireframe can be installed just like any ProcessWire module. Just clone or download it to your site/modules/ directory and install. It doesn't, though, do a whole lot of stuff on itself – please check out the documentation site for a step-by-step guide on setting up the directory structure, adding the "bootstrap file", etc. You may find it easier to install one of the site profiles mentioned above, but note that this process involves the use of Composer. In the case of the site profiles you can install ProcessWire as usual and download or clone the site profile directory into your setup, but after that you should run "composer install" to get all the dependencies – including the Wireframe module – in place. Hard requirements for Wireframe are ProcessWire 3.0.112 and PHP 7.1+. The codebase is authored with current PHP versions in mind, and while running it on 7.0 may be possible, anything below that definitely won't work. A feature I added just today to the Wireframe module is that in case ProcessWire has write access to your site/templates/ directory, you can use the module settings screen to create the expected directories automatically. Currently that's all, and the module won't – for an example – create Controllers or layouts for you, so you should check out the site profiles for examples on these. (I'm probably going to include some additional helper features in the near future.)

      This project is loosely based on an earlier project called pw-mvc, i.e. the main concepts (such as Controllers and the View layer) are very similar. That being said, Wireframe is a major upgrade in terms of both functionality and architecture: namespaces and autoloader support are now baked in, the codebase requires PHP 7, Controllers are classes extending \Wireframe\Controller (instead of regular "flat" PHP files), implementation based on a module instead of a collection of drop-in files, etc.
      While Wireframe is indeed still in a relatively early stage (0.3.0 was launched today, in case version numbers matter) for the most part I'm happy with the way it works, and likely won't change it too drastically anytime soon – so feel free to give it a try, and if you do, please let me know how it went. I will continue building upon this project, and I am also constantly working on various side projects, such as the site profiles and a few unannounced helper modules.
      I should probably add that while Wireframe is not hard to use, it is more geared towards those interested in "software development" type methodology. With future updates to the module, the site profiles, and the docs I hope to lower the learning curve, but certain level of "developer focus" will remain. Although of course the optimal outcome would be if I could use this project to lure more folks towards that end of the spectrum... 🙂
