## Planned for v0.3.0
|
|
|
|
- automatically wrap subscriptions in a `reaction` (removing the need for over
|
|
10 keystrokes per handler!!). Just kidding there are better reasons than that.
|
|
- develop the testing story.
|
|
- modifiy todoMVC for new subscriptions approach
|
|
- document new approach
|
|
- move contents of README across to Wiki. Make Readme simpler and instructive.
|
|
- produce a more fully featured todomvc (beyond the standard one), todomvc-with-extras
|
|
- use `enrich` to handle todo duplication
|
|
- add prismatic schema
|
|
- show testing
|
|
- show debug
|
|
- undo
|
|
|
|
|
|
### Headline
|
|
|
|
- new, easy way of creating and registering subscription handlers.
|
|
- new event handler middleware `log-ex` for correctly printing handler stacktraces.
|
|
See [explanation](https://github.com/Day8/re-frame/wiki/Debugging-Event-Handlers#1-an-exception-is-thrown).
|
|
- ongoing improvements to the docs in Wiki
|
|
|
|
### Other
|
|
|
|
- move to newly released reagent v0.5.0
|
|
- fix undo bug which could result in incorrect explanations.
|
|
- middleware `after` and `enrich` now call the supplied function `f` with
|
|
both `db` and `v` (previously just `db`). Because javascript is so forgiving
|
|
about function arity, this change is backwards compatible.
|
|
- improve todomvc's use of localstorage
|
|
- experimental work with slimmer.js for testing
|
|
- correct README wiki link
|
|
- license.txt was incorrectly named previously
|
|
|
|
|
|
## v0.2.0 (2015-03-06)
|
|
|
|
### Breaking
|
|
|
|
Renames:
|
|
- `register-pure-handler` renamed to `register-handler` (and existing low level `register-handler` becomes `register-handler-base` but is not a part of the API).
|
|
- remove `apply-event` middleware and replace with similar `trim-v`
|
|
- rename `register-subs` to `register-sub` (avoid confusion over possible plurals)
|
|
- rename `set-max-undos` to `set-max-undos!`
|
|
|
|
Changes:
|
|
- `undoable` middleware is now a factory. Where before you used this `undoable`,
|
|
you must now use this `(undoable "some explanation")`. See further below.
|
|
|
|
### Headline
|
|
|
|
- exceptions in handler now reported more sanely via console.error.
|
|
(core.async really messes with a good stack)
|
|
- example `todomvc` available in examples folder.
|
|
- Wiki documentation is now more substantial.
|
|
- introduce new handler middleware: `debug`, `enrich` and `after`
|
|
|
|
### Other:
|
|
- exceptions in a go loop are a special type of hell. Improve the reporting of exceptions happening in event handlers.
|
|
- allow Middleware to be registered as a vector. data > functions > macros
|
|
- fix two bugs in undo implementation
|
|
- name licence file correctly, thanks to @smith
|
|
- fix typo in readme, thanks to @btheado
|
|
- Readme now admits to 200 lines of code, not 100.
|
|
- dispatch now explicitly returns nil
|
|
- travis integration (not that we have any tests currently)
|
|
|
|

|
### Details On Undo Changes
|
|
|
|
The undo/redo feature built into re-frame is now more functional
|
|
(at the cost of a breaking change).
|
|
|
|
There is now an explanation associated with each undo state describing
|
|
modification. This allows an app to inform the user what actions
|
|
they will be undoing or redoing.
|
|
|
|
Previously `undoable` was simply middleware, but it is now a middleware factory.
|
|
|
|
Essentially, that means you can't use it "plain" anymore, and instead you must
|
|
call it, like this `(undoable "Some explanation")`
|
|
|
|
The `explanation` provided to undoable must be either a `string` (static
|
|
explanation) or a function `(db event) -> string`, allowing you to customize
|
|
the undo message based on details of the event.
