Their value will now only be calculated as needed (i.e when deref
is called), which should make debugging them much easier.
This also makes updating the atom they are relying on cheaper.
Instead of passing an atom, you can now pass a function.
That function is passed one argument (the path provided to cursor)
when deref-ing, and two arguments (path and new value) when
resetting.
Remove the old setter, and the currying version.
Tests and doc site can now run without node, using only
"lein figwheel". Tests and site are then re-run automatically
whenever a source file changes.
The doc site is now generated into "outsite/public", and can be
copied into the "gh-pages" branch with "make build-gh-pages".
"make push-gh-pages" builds the doc site and pushes it upstream
to the gh-pages branch there.
Generation of html pages is now handled completely in
ClojureScript, loaded from "bin/gen-site.js".
Link handling is a bit simplified.
The new names correspond to changes in React in 0.12.0.
Both render-component and render-component-to-string are kept for
backward compatibility.
Call React.render etc to avoid deprecation warnings from React.
Adds RCursor type: wraps Reagent's RAtom along with a path that provides focus into a specific part of that atom.
Adds reagent.ratom/cursor as a constructor for the RCursor type.
Adds reagent.core/cursor as the public API. This can be called with just a path, and returns a function that accepts a Reagent atom, or with both a path and an atom.
Dereferences of a cursor behave like get-in on the underlying atom with the specified path.
If you reset! a cursor, it behaves like a swap! assoc-in on the underlying atom. If swap! a cursor, it behaves like a swap! update-in on the underlying atom.
This is actually a bug in ClojureScript
(http://dev.clojure.org/jira/browse/CLJS-777). In regular Clojure a
`MultiFn` is `ifn?`, but in ClojureScript it wasn't. The bug is now
fixed
(525154f2a4)
but not yet released.
This code can be reverted after Reagent's ClojureScript version is
updated.
