Rocker v0.13.0 Release Notes

Release Date: 2016-09-19 // over 7 years ago
    • Major built-in support for null safe handling! This release will help you avoid NullPointerExceptions in numerous areas.
    • NOTE: some significant changes under-the-hood. Templates will be source compatible with older versions, but will likely have runtime issues (e.g. templates compiled with v0.12.0 will likely have runtime errors with v0.13.0) We recommend you recompile all your templates with v0.13.0+.
    • NOTE: default html escaping now uses an internal version rather than apache commons. This internal version is slightly faster, but also only escapes 5 entities (matches the entities Guava encodes by default). The previous version used Apache commons lang3 which included many other entities that are irrelevant with modern widespread usage of utf-8.
    • New @() eval expression will evaluate the expression and then render it
    • New @?value expression will only render the value if its not null
    • New @value?:defaultValue null ternary expression will either render the value if not null or will render the defaultValue. The defaultValue can include strings or literals. The ternary operation also follows short-circuit evaluation so defaultValue is only evaluated if value was null.
    • New @with? expression will either render the with block or you can optionally include an else block that will be rendered instead.
    • If guava is on the classpath, its html escaper will be used instead of Rocker's internal default version. Its about 3-4x faster. Its such a large dependency, its only optional, so simply add guava to your classpath to activate.
    • rocker-runtime no longer depends on Apache commons lang3. Its now only a dependency of rocker-compiler.
    • More efficient @for loops that use primitive array types.
    • Antlr dependency from v4.5 to v4.5.3
