configuration required.

Roadmap
|
|
-------
|
|
|
|
> **WARNING**: Before 1.0.0, expect that bug fixes _will not_ be backported to older versions. Backwards incompatible changes
|
|
may be introduced in minor 0.X.Y versions, where X changes.
|
|
|
|
0.0.1 - First party `psr4` classes
|
|
|
|
0.1.0 - Third party `psr4` classes
|
|
|
|
0.2.0 - `classmap` support.
|
|
|
|
0.3.0 - `files` support
|
|
|
|
0.4.0 - `psr0` support
|
|
|
|
0.5.0 - Additional features:
|
|
|
|
Various ideas:
|
|
|
|
* ~~`ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE)`.
|
|
Providing classes multiple namespaces deep.~~ (included v0.3-beta)
|
|
|
|
* `ClassFinder::getClassesImplementingInterface('TestApp1\Foo', 'TestApp1\FooInterface', ClassFinder::RECURSIVE_MODE)`.
|
|
Filtering classes to only classes that implement a namespace.
|
|
|
|
* `ClassFinder::debugRenderReport('TestApp1\Foo\Baz')`
|
|
Guidance for solving "class not found" errors resulting from typos in namespaces, missing directories, etc. Would print
|
|
an HTML report. Not intended for production use, but debugging.
|
|
|
|
1.0.0 - Better compliance with semantic versioning.
