Bug fixes
|
||||||
|
---------
|
||||||
|
|
||||||
|
* Property setter op-assignments now work properly.
|
||||||
|
|
||||||
|
Breaking changes
|
||||||
|
----------------
|
||||||
|
|
||||||
|
* `ModuleResolver` trait methods take an additional parameter `source_path` that contains the path of the current environment. This is to facilitate loading other script files always from the current directory.
|
||||||
|
* `FileModuleResolver` now resolves relative paths under the source path if there is no base path set.
|
||||||
|
* `FileModuleResolver::base_path` now returns `Option<&str>` which is `None` if there is no base path set.
|
||||||
|
|
||||||
|
New features
|
||||||
|
------------
|
||||||
|
|
||||||
|
* `FileModuleResolver` resolves relative paths under the parent path (i.e. the path holding the script that does the loading). This allows seamless cross-loading of scripts from a directory hierarchy instead of having all relative paths load from the current working directory.
