This is a textformatter module that will automatically replace titles of other pages on your site with links to those pages. For example, if you have a template glossary-term, and mention the exact title of one page using that template in a textfield, the title will be automatically linked to that page (if the textfield uses that formatter). This is good for SEO, and saves you some manual labour. You can configure which templates should get automatically linked, and of course the formatter is only active for the fields you add this formatter to. Note that if you need more manual control over when and where titles are automatically linked, you're probably better of using Autolink from a Glossary by @mr-fan.
Features
Allows you to limit the automatic links by template. Only includes published & visible pages by default, with an option to include hidden pages. Automatically excludes the current page, with an option to change that behaviour. Allows you to configure the minimum title length for linked pages. Doesn't overwrite existing links, and detects most edge cases (titles inside other tag's attributes, titles inside existing links et c.). Supports multi-language sites. Titles will only be linked if a title in the current language is set. Can add configurable attributes to all automatically created links. Includes the ability to use page fields as replacement patterns for attributes. For example, you can create CSS classes that include the name of the template of the linked page. Prefer oldest or newest page in the case of duplicate titles. Queries the database directly for improved performance. Has options to switch between case sensitive and case insensitive modes, and force case sensitive behaviour even for case insensitive database collations. Allows you to overwrite the module configuration via the API to call the module with different settings for different requirements on the same page. Download & Documentation
The module is now available in the modules directory: https://modules.processwire.com/modules/textformatter-page-title-links/
You can download & install it through the backend using the classname TextformatterPageTitleLinks.
To install it manually, download or clone the module from the Github repository into your site/modules folder and install through the backend.
The complete documentation can be found in the README in the repository. Make sure to check out the module configuration page after installing the module.
Requirements
PHP 7.1 or higher ProcessWire 3+ (it will probably work in older versions, I haven't tested those though). This is my first module, I hope it may become useful to some of you 🙂
If you find any errors or have some other suggestions or feedback, let me know!

File Info
A textformatter module for ProcessWire. The module can add information to local Pagefile links in two ways:
As extra markup before, within or after the link As data attributes on the link (handy if you want to use a Javascript tooltip library, for instance) Screenshots
Module config
Example of output
Installation
Install the File Info module.
Add the textformatter to one or more CKEditor fields.
Configuration
Add markup action (and general)
Select "Add markup to links" Select the Pagefile attributes that will be retrieved. The attribute "filesizeStrCustom" is similar to the core "filesizeStr" attribute but allows for setting a custom number of decimal places. If you select the "modified" or "created" attributes then you can define a date format for the value. Enter a class string to add to the links if needed. Define the markup that will be added to the links. Surround Pagefile attribute names in {brackets}. Attributes must be selected in the "Pagefile attributes" section in order to be available in the added markup. If you want include a space character at the start or end of the markup then you'll need >= PW 3.0.128. Select where the markup should be added: prepended or appended within the link, before the link, or after the link. Add data attributes action
Select "Add data attributes to links" Select the Pagefile attributes that will be retrieved. These attributes will be added to the file links as data attributes. Attributes with camelcase names will be converted to data attribute names that are all lowercase, i.e. filesizeStrCustom becomes data-filesizestrcustom. Hook
If you want to customise or add to the attributes that are retrieved from the Pagefile you can hook TextformatterFileInfo::getFileAttributes(). For example:
$wire->addHookAfter('TextformatterFileInfo::getFileAttributes', function(HookEvent $event) { $pagefile = $event->arguments(0); $page = $event->arguments(1); $field = $event->arguments(2); $attributes = $event->return; // Add a new attribute $attributes['sizeNote'] = $pagefile->filesize > 10000000 ? 'This file is pretty big' : 'This file is not so big'; $event->return = $attributes; });

UPDATE: I have published a stable version of this module!
Discussion thread:

Hello there,
I'm working on a tiny textformatter module that searches the text for titles of other pages on your site and creates hyperlinks to them. I'm not sure if something like this exists already, but I haven't found anything in the module directory, so I wrote my own solution 🙂
It's not properly tested yet and is still missing some functionality I would like to implement, so at the moment it should be considered in BETA. Features include limiting the pages that will get searched by template, and adding a custom CSS class to the generated hyperlinks. As I'm writing this I noticed that it will probably include unpublished and hidden pages at the moment, so yeah ... it's still in development alright 😅
You can download the module from Github:
https://github.com/MoritzLost/TextformatterPageTitleLinks
There's some more information in the readme as well.
Anyway, let me know what you think! I'm happy about any feedback, possible improvements or ideas on how to improve the module. Cheers.

Hey Ryan, hey friends,
we, Mobile Trooper a digital agency based in Germany, use ProcessWire for an Enterprise-grade Intranet publishing portal which is under heavy development for over 3 years now. Over the years not only the user base grew but also the platform in general. We introduced lots and lots of features thanks to ProcessWire's absurd flexibility. We came along many CMS (or CMFs for that matter) that don't even come close to ProcessWire. Closest we came across was Locomotive (Rails-based) and Pimcore (PHP based).
So this is not your typical ProcessWire installation in terms of size.
Currently we count:
140 Templates (Some have 1 page, some have >6000 pages)
313 Fields
~ 15k Users (For an intranet portal? That's heavy.)
~ 195 431 Pages (At least that's the current AUTOINCREMENT)
I think we came to a point where ProcessWire isn't as scalable anymore as it used to be. Our latest research measured over 20 seconds of load time (the time PHP spent scambling the HTML together). That's unacceptable unfortunately. We've implemented common performance strategies like:
We're running on fat machines (DB server has 32 gigs RAM, Prod Web server has 32gigs as well. Both are running on quadcores (xeons) hosted by Azure.
We have load balancing in place, but still, a single server needs up to 20 sec to respond to a single request averaging at around about 12 sec.
In our research we came across pages that sent over 1000 SQL queries with lots of JOINs. This is obviously needed because of PWs architecture (a field a table) but does this slow mySQL down much? For the start page we need to get somewhere around 60-80 pages, each page needs to be queried for ~12 fields to be displayed correctly, is this too much? There are many different fields involved like multiple Page-fields which hold tags, categories etc.
We installed Profiler Pro but it does not seem to show us the real bottleneck, it just says that everything is kinda slow and sums up to the grand total we mentioned above.
ProCache does not help us because every user is seeing something different, so we can cache some fragments but they usually measure at around 10ms. We can't spend time optimising if we can't expect an affordable benefit. Therefore we opted against ProCache and used our own module which generates these cache fragments lazily.
That speeds up the whole page rendering to ~7 sec, this is acceptable compared to 20sec but still ridiculously long.
Our page consists of mainly dynamic parts changing every 2-5 minutes. It's different across multiple users based on their location, language and other preferences.
We also have about 120 people working on the processwire backend the whole day concurrently.
What do you guys think?
Here are my questions, hopefully we can collect these in a wiki or something because I'm sure more and more people will hit that break sooner than they hoped they would:
- Should we opt for optimising the database? Since >2k per request is a lot even for a mysql server, webserver cpu is basically idling at that time.
- Do you think at this point it makes sense to use ProcessWire as a simple REST API?
- In your experience, what fieldtypes are expensive? Page? RepeaterMatrix?
- Ryan, what do you consider as the primary bottleneck of processwire?
- Is the amount of fields too much? Would it be better if we would try to reuse fields as much as possible?
- Is there an option to hook onto ProcessWires SQL builder? So we can write custom SQL for some selectors?
Thanks and lots of wishes,
Pascal from Mobile Trooper

As I mentioned in this issue, I've create a new textformatter for ParsedownExtraPlugin, which adds some oomph to your markdown.
Repo: Parsedown Extra Plugin
Unlike the built-in textformatter for Parsedown and Parsedown Extra, this should be used when you want to use Extra with additional configuration/customisation.
Some examples:
### Test {.heading} - A [external link](https://google.com/){.google} with `google` as a class that opens in a new tab if the config property is set. - [Another link](/page){target=_blank} that opens in a new tab even though it isn't external. ```html .html <p>Test</p> ``` There's some config options available to you, such as setting attributes on all/external images and links, setting table and table-cell alignment classes, adjusting footnote classes and IDs, adding <code> attributes to their parent <pre> elements, and changing the <code> class if your syntax highlighter does not use language-*.
I was thinking about adding the ability to make links open in a new tab by appending a plus to the link syntax, but only external links should be opening in a new tab anyway. Further, this would add extra, unnecessary processing time.
Please let me know if you bump into any problems. ☺️
