5.0.0

Version 5.0 is the next major milestone in the development of the Fluid templating engine. Based on the previous efforts that went into Fluid 4, Fluid 5 continues to refactor and to modernize the underlining source code, which sometimes requires introducing strategic breaking changes. All breaking changes in this release have been pre-announced in Fluid 4, both in the changelog and by applying the @deprecated annotation or emitting a deprecation notice in the code.

These breaking changes allow us to ship meaningful new features that weren't possible before:

Streamlined ViewHelper Argument Validation

ViewHelpers now use the StrictArgumentProcessor to validate ViewHelper arguments. This means that argument validation behaves the same with ViewHelpers and with the <f:argument> ViewHelper, which was introduced with Fluid 4.2. While the new validation might require some adjustments in existing projects, it has clear advantages: ViewHelper instances can actually rely on the types specified in their API to be checked properly by Fluid, which makes a lot of custom validation code obsolete.

The new argument validation adds support for union types as well as iterable, countable and callable, which allows ViewHelpers to define a clearer API.

See #1062, #1074, #1194 and #1226 for more details.

Template File Resolving and File Extension

Fluid 5 now features an internal fallback chain for template file names. Template files are now resolved in the following order (first match wins):

templateRootPath: templates/
template: myTemplate
format: html

1. templates/myTemplate.fluid.html
2. templates/myTemplate.html
3. templates/myTemplate
4. templates/MyTemplate.fluid.html
5. templates/MyTemplate.html
6. templates/MyTemplate

This means that it's no longer necessary for template names to start with an uppercase character. Also, there is a new dedicated file extension *.fluid.* for Fluid templates: *.fluid.html instead of *.html, *.fluid.xml instead of *.xml, and so on. Because of the fallback chain, both can be added without breaking potential overrides from other template paths.

We recommend switching to the new file extension if Fluid 5 can be a hard requirement for your project. Otherwise, just stick to the existing general file extensions. The new file extension is entirely optional and will not be a requirement.

See #1243 and #1258 for more details.

Simplified Cache Warmup

Fluid 5 comes with a much simpler way to warmup the template cache in your project. The existing cache warmup functionality has been removed and replaced by a new implementation that requires much less configuration and context. By default, it makes use of the new *.fluid.* file extension to discover all Fluid templates in your project.

bin/fluid warmup \
    --cacheDirectory examples/cache/ \
    --path examples/Resources/
    --path examples/ResourceOverrides/

See #1224 for more details.

Alternative Syntax for CDATA Sections

A long-standing issue in Fluid templates has been that the Fluid variable and inline ViewHelper syntax collides with inlined CSS or JavaScript code. This issue has now been addressed with Fluid 5: A new alternative syntax has been introduced that makes collisions between CSS/JavaScript and Fluid far less likely.

The normal inline and variable syntax uses single curly braces { } as tokens in Fluid templates. In <![CDATA[ ]]> sections, this syntax are now ignored. Instead, three curly braces {{{ }}} can be used to call Fluid ViewHelpers or to access variables. The tag-based syntax is disabled altogether in CDATA sections.

See #1246 and the documentation for more details: Avoiding syntax collision with JS and CSS.

4.5.0

Fluid 4.5 makes advances in two areas: It contains a range of new ViewHelpers that should make the life of integrators easier. Also, it includes deprecations in preparation for the upcoming Fluid 5.0, which will contain various breaking changes.

New ViewHelpers in Fluid 4.5:

• <f:range> creates an array containing the specified range of integers
• <f:length> returns the length of a given string
• <f:merge> merges two given arrays into one
• <f:startsWith> and <f:endsWith> check if a given string starts or ends with another string
• <f:round>, <f:ceil> and <f:floor> provide various ways to round floats
• <f:min> and <f:max> return the minimum/maximum value in the given array
• <f:contains> checks if a given array/string contains the given value

The deprecations and preparations for the upcoming Fluid 5.0 are listed in the documentation: Changelog 4.x
