Weekly update – 18 April 2025

This week on the dev branch there are some issue fixes and new features. ProcessWire’s modal JS alert functions have been upgraded to use Uikit modals. Previously they were using Vex modals, but it appears that Vex is no longer maintained, so when we ran into an issue with them it just made sense to switch to Uikit for this, at least when AdminThemeUikit is the current admin theme. The JS functions affected are ProcessWire.alert(), ProcessWire.confirm() and ProcessWire.prompt(). All of which can be found in ProcessWire’s main.js file used by admin themes.

ProcessWire’s Markup Regions output method was updated this week to support class removal by wildcard or regular expression. When you specify a class attribute with a class name that starts with “-“ that means that you want to remove that class from the element you are overriding/appending/prepending. Previously you had to specify the full class name you wanted to remove. Now you can specify a wildcard like this:

<div id="content" class="-uk-width-*" pw-append></div>

That would make it remove all classes from #content that start with "uk-width-". You may place the wildcard anywhere in the expression that you want to, enabling you to remove by prefix or suffix. But if that’s not enough, you can also specify a regular expression like this, which would do the same thing as the above:

<div id="content" class="-/^uk-width-.*$/" pw-append></div>

That's probably overkill for most, but between the “/“ delimiters, you may use any PCRE regular expression.

Usually when we add a class to a markup region, we just specify it like a regular HTML class attribute. But if you want to add a class that would match what you are removing,  you’ll want to prefix your class name with a plus sign. That tells the Markup Regions processor not to remove it even if it matches your rule. For example, the following would remove all uk-width classes and then add a uk-width-1-4 class:

<div id="content" class="-uk-width-* +uk-width-1-4" pw-append></div>

Regarding the new ProcessWire website: it’s nearly done except for the homepage. I’m saving the best part for last. I’m not saying the site will launch tomorrow, as there’s still a lot of detail work to take care of too. But I did want to say that a lot of progress has been made and hopefully it won’t be too much longer before we launch it. Thanks for reading and have a great weekend!
