Release Notes

square/kotlinpoet (com.squareup:kotlinpoet-ksp)

v2.0.0

Compare Source

Thanks to @​brokenhappy, @​tajobe, @​niyajali, @​ForteScarlet for contributing to this release.

This release is source- and binary-compatible with KotlinPoet 1.x.

The most important behavior change in this release is that spaces in generated code don't wrap by default anymore.

KotlinPoet 1.x used to replace space characters with newline characters whenever a given line of code exceeded the length limit. This usually led to better code formatting, but could also lead to compilation errors in generated code. Non-breaking spaces could be marked by the · character, but the discoverability of this feature wasn't great.

KotlinPoet 2.0 does not wrap spaces, even if the line of code they occur in exceeds the length limit. The newly introduced ♢ character can be used to mark spaces that are safe to wrap, which can improve code formatting. The · character has been preserved for compatibility, but its behavior is now equivalent to a regular space character.

• New: Kotlin 2.0.10.
• New: Spaces don't break by default.
• New: New ♢ placeholder representing a space that is safe to wrap.
• New: Add KSTypeAlias.toClassName(). (#​1956)
• New: Add KSType.toClassNameOrNull(). (#​1956)
• Fix: Enum classes that only have an init block now also generate the required semicolon. (#​1953)
• Fix: Preserve typealiases in KSAnnotation.toAnnotationSpec(). (#​1956)
• Fix: Preserve nullability in KSType.toClassName(). (#​1956)
