Hanna Code

Recommended Posts

Hi,

first of all: I think the addition of this particular module is great! I can think of quite a few itches I could scratch with that.

Something I've been wondering about: How would I go about accessing specific repeater fields with the Hanna Code.

Say for example I have a repeater including a Text field, a Date and a Price.

I'd fill the text Field with

Come on the [[date]], bring [[price]]$ in small used bills. Thank you for your cooperation.

The frontend should obviously render this as

Come on the 4th of July, bring 50$ in small used bills. Thank you for your cooperation.

If Text, Date and Price where just page fields, this would be pretty obvious. However for them being fields inside a repeater I think there's something like the jQuery siblings selector needed, but I don't see anything like that in the api documentation.

Any input on this would be very much appreciated :-)

Is there any way to get Hanna code to render within Hanna code?

I've got two tags.

[[tooltip]] and [[info]]

What I'm trying to do is this:

[[tooltip text="[[info]]" tooltip="test"]]

And then using the following snippet within the [[tooltip]] hanna code:

$hanna = wire('modules')->get('TextformatterHannaCode');
echo "<a class='tooltip' href='#' title='{$tooltip}'>".$hanna->render($text)."</a>";

This doesn't seem to be working unfortunately. Any ideas on how to make this work?

[[info]] just echos out an img tag.

Cheers

@Sinmok,

From your example you are trying to add a tooltip.   I don't know what front-end framework you are working with on your website, however with Zurb Foundation 4 you can do a tooltip using Hanna Code as follows:

<span data-tooltip class="has-tip" title="Tooltips are awesome, you should totally use them!">extended information</span>

Your Type would be Text/HTML.

Then you just add the Hanna Code in a field that supports Hanna Code.

This may not answer your specific request for having Hanna Code within Hanna Code, but it does show how a tooltip can be added using Hanna Code.  Good Day.

This turned out to be an issue with the order of variables returned by core TemplateFile::getArray. It was doing an array_merge which gave preference to API variables, preventing them from being overwritten. Maybe that's a good thing in general, but I don't think we want that limitation. I went ahead and changed it in dev. Now it gives preference to local variables, which enables Hanna Code to provide the behavior it was supposed to. 

I think I've found another issue related to the use of $page in a Hanna code: if the field containing the hanna code is in a repeater, $page seems to point to something internal to the repeater instead of pointing to the page containing the repeater field.

Example with a hanna code echoing the page id:

// in a field directly in the home page
echo $page->id;
--> 1

// in the field from a repeater on the same home page
echo $page->id;
--> 1060

From what I understand by looking at the repeater module source code, repeaters are implemented with pages. So the observed behavior is probably a side effect of this.

Any idea of how to fix this ?

@jean-luk

Yes repeaters are in fact internal pages, so doing the following should help (not tested):

if ($page instanceof RepeaterPage) {

$id = $page->parent->id;

} else {

$id = $page->id;

} 

echo $id;

@slkwrm
 
Thanks for the hint.
 
Actually it turns out that the repeater page's parent is not the page where the repeater field is, but this page can be got by calling the method getForPage. So the correct code is:

$containerPage = $page;
if ($page instanceof RepeaterPage) {
   $containerPage = $page->getForPage();
}

// can be checked with
echo $containerPage->id;

I added this container page calculation at the right place (I hope!) in TextformatterHannaCode.module and the repeater field case now seems to work for hanna codes.

Finally I'm not sure about the best way of handling this hanna-code-inside-reapeater-field case…
 
On one hand, a naive hanna code writer like myself would expect $page to refer to the user-visible field container page;
 
On the other hand, having a reference to the current "repeater page" can be useful in many cases, like this one:

If Text, Date and Price where just page fields, this would be pretty obvious. However for them being fields inside a repeater I think there's something like the jQuery siblings selector needed, but I don't see anything like that in the api documentation.
 
Any input on this would be very much appreciated  :-)

 
Maybe a solution would be to have two different PHP variables accessible from within the hanna code, where the one referring to the repeater page would be null if the current field is not part of a repeater.
 
Easy to implement, but, as always, not so easy to keep it consistent with the rest of the PW API. 
 
Ryan, your opinion about this?

Got a feeling this is a server issue but I'm getting an error I can't seem to recover from after saving a simple HTML code:

Method Sanitizer::entities does not exist or is not callable in this context

I can't even load the Hanna Code config screen - even if I try to ununstall/install it again. It hasn't written any files to /site/assets/cache/HannaCode/ either.

I'm running PW 2.2.9 on PHP version 5.2.17. Stuck! :)

Marty, not sure why there is no sanitizer entities method there. Maybe we didn't have it in 2.2, I don't recall. Try replacing your wire/core/Sanitizer.php file with a fresh copy. It should be fine to take the one from 2.3 or 2.4.

Jean-luc, glad to see you found the getForPage method. This is exactly the way that repeater pages are meant to refer to their containing page, whether in a Hanna code or elsewhere.

Perhaps this has come up already in this thread, haven't read it all, and I don't want to be a nay-sayer, but if it's primarily aimed at super users i.e. us devs, why have a GUI at all? Why not leave out the whole visual stuff and have HannaCode parse the text and search for template files (or template file in a subdir like templates/hanna) with the HannaCode name.

[[my-hanna foo=bar]] looks for templates/hanna/my-hanna.php and passes the params like with any other regular template. This way we can edit our hanna-codes in our IDE or text editor of choice with all the highlighting and we can push it into version control, no need to fiddle around with exports or imports between installations.

Am I missing something?

@owzim, just throwing in some possible reasons:

  • Not all superusers are developers. Whether or not that's a good thing, Hanna Code allows people with no access to actual code to add features that would normally require such an access -- or at least some way to edit files on disk.
  • It's not just about PHP code. Tiny snippets of random HTML or JS can be easily added without having to add files for those too.
  • Hanna Code provides easy way to quickly sketch and test code snippets you're not going to need in the longer term. This is also handy when working in an environment where same site exists on multiple locations sharing database but not code (in which case moving a snippet of code in disk from one location to another would typically require extra steps).

That being said, I really believe that Hanna Code would benefit from more fine-grained access management.

This could mean three different permissions: hanna-code-html, hanna-code-javascript and hanna-code-php. Or perhaps just two -- hanna-code to add all sorts of snippets and another, limited permission for creating only HTML + JS snippets.

The way it is right now, I can't imagine giving a client access to creating their own Hanna Code snippets, but if it allowed me to limit that access to less destructive features this module would have a lot more potential.

Edit: almost forgot to mention that of course you could already add the sort of thing you're talking about, though the syntax would be slightly different (filename as a variable). GUI doesn't make that impossible and you don't really have to use it unless you want to :)

...sorry don't read the whole threat, too

short questions about HannaCode:

-> Is ther a Overview/Post with contributed examples for "Hannas"

-> If yes who can i contribute

i've got a few of this little helpers from another system (the CMS Argos and i used and contributed before find PW) there was an Admintool that's called "Droplets". There exists a "Dropletgallery" and we had a WYSIWYG Plugin for choose one for the editor to use.

Best Regards mr-fan


Example for a "dropletCode" could this used in Hanna as it is or need special threatment or changes...

//:genQR creates QR Codes with google Charts API
//:Use: [[genQR?size=150&link=http://what-ever.com]]
 
 Parameters:
 $size - default is 200 px
 $link - default if nothing set is google.com
 
if ( !isset($size) ){    $size = 200; };
$width = $size;
$height = $size;
if ( !isset($link) ){ $link = "http://google.com"; };
$url = urlencode(".$link."); 
return "<img src=\"http://chart.googleapis.com/chart?chs={$width}x{$height}&cht=qr&chl=$url\" />";

just for the starting point - i've more like this to share if it's usefull :rolleyes:


a starting point coudl even be a gist repo?

@ozwim - not sure if you already know about this, but i follow Soma's suggestion and have a folder called 'hannas' and then keep all the hanna codes there; and then using this in the hanna code itself:

include($config->paths->templates . "hannas/some-hanna-code.php");

@mr-fan - that's great - we should try and setup a place to share hanna codes... maybe github? I have a lot of examples also

Mr-fan, you're right, the PW Hanna system seems to be very like the "WB-droplets" we are familiar with, coming from WebsiteBaker. There is even an integration with the editor, called HannaCodeHelper. Check it out in the Modules repo.

Ok first try seems to work with given atr in Hanna Code like:

[[genQR size="400" link="http:\\google.com"]]

but the fallback option would be nice to have a QR Code from the current Link - May used for events or articles....

heres my code for first hanna experiments may i missed the wrong API handling??

<?php 

//:genQR creates QR Codes with google Charts API
//:Use: [[genQR?size=150&link=http://what-ever.com]]
//
// Parameters:
// $size - default is 200 px
// $link - default if nothing set is google.com
 
if ( !isset($size) ){    $size = 200; };
$width = $size;
$height = $size;
if ( !isset($link) ){ $link = $page->httpUrl; };

echo "<img src=\"http://chart.googleapis.com/chart?chs={$width}x{$height}&cht=qr&chl=$link\" />";
//  to testing link url echo "<p>$link</p>";

like written it works with a link="some.link" and if not it doesn't take the current url $page->httpUrl;
:(

for a repo would be a cool place to have something like a hanna code gallery or overview of some snippets...??

like in our old system (argos and mine) there was a snippetgallery for this: http://www.websitebakers.com/pages/droplets/official-library.php

maybe there is some inspriation for PW HannaCode or if i getting more familiar with PW i can port some for usage with PW.

To make PW more user friendly (especially for non-coders) I think it would be best to create a Hannacode subsection in the Modules section on the regular PW site. Personally I think regular users should not be send to some Github page, as it is far too technical, intimidating, and therefore unfriendly environment for non-coders. Hannacodes are (as far as I can tell, as a newer than new newbie) ready to use code snippets and as such could be offered on the regular site.

I am not quite sure whether you are having problems with your code working or not. It works perfectly for me if I don't define a link - it defaults to the current page and if I do define it goes to that link. Can you tell us exactly what isn't working and what the link is instead?

Effectively they are/do the same thing. I think Ryan got the name and inspiration from WP's Hana code.

@Argos: PW is much more Coding like our older System but for the frontend it isn't that hard to use it seems to me. For the Frontend it depends an procedural Coding combining with the PW API it's really amazing - Backend and process are mostly OOP PHP and a little bit more devwork

so i don't know what is wrong:

[[genQR size="200"]]

and same code as above but with echo the $link give me a screen like this (second QR is emty with no $link is given)

(....system is PW 2.4 clean install with some testaddons and the basic-site profil)

thanks for take a look

I am at a loss for why it isn't working for you. Not that it matter, but here is a slightly cleaned up version of your code:

if (!isset($size)) $size = 200;
if (!isset($link)) $link = $page->httpUrl;

echo "<img src='http://chart.googleapis.com/chart?chs={$size}x{$size}&cht=qr&chl=$link' />";

You had unnecessary curly braces and extra semi-colons and also since these are square, there is no need to define the width and height separately. If you wanted you could even make it a one liner:

echo "<img src='http://chart.googleapis.com/chart?chs=" . (isset($size) ? $size : 200) ."x" . (isset($size) ? $size : 200) ."&cht=qr&chl=" . (isset($link) ? $link : $page->httpUrl) . "' />";

Although you do sacrifice a little readability.

One other quick thing - in your google.com example, you are using backslashes instead of forwardslashes - probably just a typo :)

I'm sorry, I wasn't clear enough. What I meant was, what is the difference between the modules "Hannacode" and "Shortcode"? These are two different shortcode type modules.

Oh right - sorry I misunderstood. Both provide similar functionality, although I haven't actually used Nico's shortcode module, so not completely sure on the differences. I guess my advice would be to experiment with both and see which best provides you the functionality you need.

If it be ok - from the modside we could make a new Threat with only HannaCode Examples as Posts - i would sort them into groups in a first post? If this is welcome?

      ---- INITIAL POST FROM 2019-05-25 ----
      I wanted to let you know that I am currently working on a new ProcessWire module that fully integrates the Snipcart Shopping Cart System into ProcessWire. (this is a customer project, so I had to postpone the development of my other module GroupMailer).
      The new module SnipWire offers full integration of the Snipcart Shopping Cart System into ProcessWire.
      Here are some highlights:
      simple setup with (optional) pre-installed templates, product fields, sample products (quasi a complete shop system to get started immediately) store dashboard with all data from the snipcart system (no change to the snipcart dashboard itself required) Integrated REST API for controlling and querying snipcart data webhooks to trigger events from Snipcart (new order, new customer, etc.) multi currency support self-defined/configurable tax rates etc. Development is already well advanced and I plan to release the module in the next 2-3 months.
      I'm not sure yet if this will be a "Pro" module or if it will be made available for free.
      I would be grateful for suggestions and hints!
      (please have a look at the screenshots to get an idea what I'm talking about)

      Update 31.7.2019: AdminBar is now maintained by @teppo. Modules directory entry has been updated, as well as the "grab the code" link below.
      ***
      Latest screencast: http://www.screencas...73-ab3ba1fea30c
      Grab the code: https://github.com/teppokoivula/AdminBar
      ***
      I put this Adminbar thingy (from here: http://processwire.c...topic,50.0.html) to modules section and to it's own topic.
      I recorded quick and messy screencast (really, my first screencast ever) to show what I have made so far. You can see it from here: http://www.screencas...18-1bc0d49841b4
      When the modal goes off, I click on the "dark side". I make it so fast on screencast, so it might seem a little bit confusing. Current way is, that you can edit, go back to see the site (without saving anything), continue editing and save. After that you still have the edit window, but if you click "dark side" after saving, then the whole page will be reloaded and you see new edits live.
      I am not sure if that is best way: there are some strengths in this thinking, but it is probably better that after saving there shouldn't be a possibility to continue editing. It might confuse because then if you make edits, click on dark side -> *page refresh* -> You lose your edits.
      ***
      When I get my "starting module" from Ryan, I will turn this into real module. Now I had to make some little tweaks to ProcessPageEdit.module (to keep modal after form submits). These probably won't hurt anything:
      if($this->redirectUrl) $this->session->redirect($this->redirectUrl); if(!empty($_GET['modal'])) $this->session->redirect("./?id={$this->page->id}&modal=true"); // NEW LINE else $this->session->redirect("./?id={$this->page->id}");   and...
      if(!empty($_GET['modal'])) { $form->attr('action', './?id=' . $this->id . '&modal=true'); } else { $form->attr('action', './?id=' . $this->id); // OLD LINE }

      Jumplinks for ProcessWire
      Release: 1.5.54
      Composer: rockett/jumplinks
      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! :)

      I've spent the last while experimenting with srcset implementation - and PageimageSrcset is the result:
      PageimageSrcset
      Provides configurable srcset and sizes properties/methods for Pageimage.
      Overview
      The main purpose of this module is to make srcset implementation as simple as possible in your template code. It does not handle images rendered in CKEditor or similar fields.
      For an introduction to srcset and sizes, please read this Mozilla article about responsive images.
      Pageimage::srcset()
      // The property, which uses the set rules in the module configuration $srcset = $image->srcset; // A method call, using a set rules string // Delimiting with a newline (\n) would also work, but not as readable $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x"); // The same as above but using an indexed/sequential array $srcset = $image->srcset([ "320", "480", "640x480 768w", "1240", "2048 2x", ]); // The same as above but using an associative array // No rule checking is performed $srcset = $image->srcset([ "320w" => [320], "480w" => [480], "768w" => [640, 480], "1240w" => [1240], "2x" => [2048], ]); // Use the default set rules with portrait images generated for mobile/tablet devices $srcset = $image->srcset(true); // Return the srcset using all arguments $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x", [ "portrait" => "320, 640", ]); // The set rules above are a demonstration, not a recommendation! Image variations are only created for set rules which require a smaller image than the Pageimage itself. On large sites this may still result in a lot of images being generated. If you have limited storage, please use this module wisely.
      Portrait Mode
      In many situations, the ratio of the image does not need to change at different screen sizes. However, images that cover the entire viewport are an exception to this and are often the ones that benefit most from srcset implementation.
      The main problem with cover images is that they need to display landscape on desktop devices and portrait when this orientation is used on mobile and tablet devices.
      You can automatically generate portrait images by enabling portrait mode. It is recommended that you use this in combination with Pageimage::focus() so that the portrait variations retain the correct subject.
      The generated variations are HiDPI/Retina versions. Their height is determined by the portrait ratio (e.g. 9:16). Variations are always generated, regardless of whether the original image is smaller. Upscaling is disabled though, so you may find that some variations are actually smaller than they say they are in their filename.
      The sizes attribute should be used when portrait mode is enabled. Pageimage::sizes will return (orientation: portrait) and (max-width: {maxWidth}px) 50vw by default, which handles the use of these images for retina devices. The maximum width used in this rule is the largest set width.
      Pageimage::sizes()
      There is no option to configure default sizes because in most cases 100vw is all you need, and you do not need to output this anyway as it is inferred when using the srcset attribute. You can use the method for custom sizes though:
      // The property $sizes = $image->sizes; // Returns 100vw in most cases // Returns '(orientation: portrait) and (max-width: {maxWidth}px)50vw' if portrait mode enabled // A method call, using a mixture of integer widths and media query rules // Integer widths are treated as a min-width media query rule $sizes = $image->sizes([ 480 => 50, "(orientation: portrait) and (max-width: 640px)" => 100, 960 => 25, ]); // (min-width: 480px) 50vw, (orientation: portrait) and (max-width: 640px) 100vw, (min-width: 960px) 25vw // Determine widths by UIkit 'child-width' classes $sizes = $image->sizes([ "uk-child-width-1-2@s", "uk-child-width-1-3@l", ]); // (min-width: 640px) 50vw, (min-width: 1200px) 33.33vw // Determine widths by UIkit 'width' classes $sizes = $image->sizes([ "uk-width-1-2@m", "uk-width-1-3@xl", ]); // (min-width: 960px) 50vw, (min-width: 1600px) 33.33vw // Return the portrait size rule $sizes = $image->sizes(true); // (orientation: portrait) and (max-width: {maxWidth}px) 50vw // The arguments above are a demonstration, not a recommendation! Pageimage::render()
      This module extends the options available to this method with:
      srcset: When the module is installed, this will always be added, unless set to false. Any values in the formats described above can be passed. sizes: Only used if specified. Any values in the formats described above can be passed. uk-img: If passed, as either true or as a valid uk-img value, then this attribute will be added. The srcset attribute will also become data-srcset. Please refer to the API Reference for more information about this method.
      // Render an image using the default set rules echo $image->render(); // <img src='image.jpg' alt='' srcset='{default set rules}'> // Render an image using custom set rules echo $image->render(["srcset" => "480, 1240x640"]); // <img src='image.jpg' alt='' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w'> // Render an image using custom set rules and sizes // Also use the `markup` argument echo $image->render("<img class='image' src='{url}' alt='Image'>", [ "srcset" => "480, 1240", "sizes" => [1240 => 50], ]); // <img class='image' src='image.jpg' alt='Image' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 1240px) 50vw'> // Render an image using custom set rules and sizes // Enable uk-img echo $image->render([ "srcset" => "480, 1240", "sizes" => ["uk-child-width-1-2@m"], "uk-img" => true, ]); // <img src='image.jpg' alt='' data-uk-img data-srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 960px) 50vw'> // Render an image using portrait mode // Default rule sets used: 320, 640, 768, 1024, 1366, 1600 // Portrait widths used: 320, 640, 768 // Original image is 1000px wide // Not possible to use portrait mode and custom sets or portrait widths in render() // Sizes attribute automatically added echo $image->render(["srcset" => true]); // <img src='image.jpg' alt='' srcset='image.320x569-srcset-hidpi.jpg 320w, image.640x1138-srcset-hidpi.jpg 640w, image.768x1365-srcset-hidpi.jpg 768w, image.jpg 1024w' sizes='(orientation: portrait) and (max-width: 768px) 50vw'> Configuration
      To configure this module, go to Modules > Configure > PageimageSrcset.
      Set Rules
      These are the default set rules that will be used when none are specified, e.g. when calling the property: $image->srcset.
      Each set rule should be entered on a new line, in the format {width}x{height} {inherentwidth}w|{resolution}x.
      Not all arguments are required - you will probably find that specifying the width is sufficient for most cases. Here's a few examples of valid set rules and the sets they generate:
      Set Rule Set Generated Arguments Used 320 image.320x0-srcset.jpg 320w {width} 480x540 image.480x540-srcset.jpg 480w {width}x{height} 640x480 768w image.640x480-srcset.jpg 768w {width}x{height} {inherentwidth}w 2048 2x image.2048x0-srcset.jpg 2x {width} {resolution}x How you configure your rules is dependent on the needs of the site you are developing; there are no prescriptive rules that will meet the needs of most situations. This article gives a good overview of some of the things to consider.
      When you save your rules, a preview of the sets generated and an equivalent method call will be displayed to the right. Invalid rules will not be used, and you will be notified of this.
      Portrait Mode
      Set Widths
      A comma limited list of widths to create HiDPI/Retina portrait variations for.
      Crop Ratio
      The portrait ratio that should be used to crop the image. The default of 9:16 should be fine for most circumstances as this is the standard portrait ratio of most devices. However, you can specify something different if you want. If you add a landscape ratio, it will be switched to portrait when used.
      Any crops in the set rules ({width}x{height}) are ignored for portrait mode variations as this ratio is used instead.
      UIkit Widths
      If your website theme uses UIkit, you can pass an array of UIkit width classes to Pageimage::sizes to be converted to sizes. The values stored here are used to do this. If you have customised the breakpoints on your theme, you should also customise them here.
      Please note that only 1- widths are evaluated by Pageimage::sizes, e.g. uk-width-2-3 will not work.
      Remove Variations
      If checked, the image variations generated by this module are cleared on Submit. On large sites, this may take a while. It makes sense to run this after you have made changes to the set rules.
      Image Suffix
      You will see this field when Remove Variations is checked. The value is appended to the name of the images generated by this module and is used to identify variations. You should not encounter any issues with the default suffix, but if you find that it conflicts with any other functionality on your site, you can set a custom suffix instead.
      Debug Mode
      When this is enabled, a range of information is logged to pageimage-srcset.
      PageimageSrcsetDebug.js is also added to the <head> of your HTML pages. This will console.log a range of information about the images and nodes using srcset on your page after a window.onresize event is triggered. This can assist you in debugging your implementation.
      The browser will always use the highest resolution image it has loaded or has cached. You may need to disable browser caching to determine whether your set rules are working, and it makes sense to work from a small screen size and up. If you do it the other way, the browser is going to continue to use the higher resolution image it loaded first.
      UIkit Features
      This module implements some additional features that are tailored towards UIkit being used as the front-end theme framework, but this is not required to use the module.
      Installation
      Download the zip file at Github or clone the repo into your site/modules directory. If you downloaded the zip file, extract it in your sites/modules directory. In your admin, go to Modules > Refresh, then Modules > New, then click on the Install button for this module. ProcessWire >= 3.0.123 is required to use this module.
