- Rename EdgeDims constructor to EdgeDims.TRBL().
- Add operator== to Size and Offset so that you can compare Size to
DebugSize in checked mode.
- Add Size.lerp().
- Add various operators to EdgeDims. (*, /, ~/, %)
- Add EdgeDims.lerp().
- Update style guide. I went there to fix an EdgeDims constructor
example, and stayed because some recent things came up and I wanted to
add them before I forgot.
Dart code now supports the full flow that the C++ code used to: version check,
download, replace app bundle. Bonus: the Dart code is much easier to follow,
thanks to async/await!
This is part 2 of a 3-part change. The first part added new mojom
interfaces, PathService and UpdateService, to the sky_services package.
This modifies the Logger_PrintString used to implement Dart's print() to
explicitly fflush stdout after writing. In some contexts stdout may not be line
buffered, such as when launching a process that runs sky using dart:io's
Process.start.
This adds a new placeholder dart package updater in sky/packages. This is built
into a snapshot and compiled into the Sky engine binary using the same
mechanism as the Dart isolate.
I also added a SkyHeadless class, similar to SkyView, used for running Dart
code without a view.
Previously layout was exiting early because the frame view
was null. Now we actually compute some layout and paint the
text. This patch makes paragraph_builder_test pass.
This patch start down the road of implementing text layout and painting without
the DOM. We can construct a basic paragraph consisting of a single run of text
and we can get through layout without crashing.
Dismissable now only depends on GestureDetector.
Added a unit test that verifies that issue #1068 has been fixed. It's commented out for now.
Cleaned up VelocityTracker.cc et al a little.
Added FlingGestureRecognizer and exposed it in the GestureDetector class. FlingGestureRecognizer is based on the Android/Chromium VelocityTracker class which computes a velocity vector for for a list of X,Y,Time tuples.
The Scrollable classes now use the FlingGestureRecognizer. Dismissable and Drawer still need to be updated
Alternating scroll gestures would sometimes be ignored because _ScrollGestureRecognizer didn't always reset its _state when the pointer[s] went up.
A Dismissable dismiss triggered by a drag and then a fling could cause the next attempt to drag-dimiss to fail.
Fixed the definition of lerpColor().
Rather than using the DOM to upload text and styling information into the
engine, this patch begins sketching a more direct API that bypasses the DOM and
CSS. Currently, this API doesn't do anything, but it's a first step.
The approach is to have a ParagraphBuilder object that can record a tree of
style interior nodes and text leaves. The build() function then applies
container-level styling information (such as TextAlign) and returns a Paragraph
object that can undergo layout and paint.
The inputs to the builder process are immutable style objects constructed from
primitive values. These primitives are currently carbon-copies of the primitive
we use in the framework today. After this patch lands, I'll convert the frame
to re-expose these values instead of re-defining them.
Now that we've hoisted Paint into the VM, we can expose these values as normal
properties. After we've updated all the callers, I'll remove the old setters.
This patch just adds them to dart:sky. A future patch will actually use them in
the framework once we've published an updated sky_engine package. Also, add
dartdoc to the classes touched in this patch.
This updates to mojo commit d259eb58aa59 and limits the roll script to
only pull in the parts of //mojo that are currently being used. More
stuff will be dropped in the future.
We still use SkPicture as our rasterization backend, but now we're uploading
our layer tree to C++. A future patch will push the layer tree deeper into the
system and we'll eventually switch backends.
Now we print Dart_GetError only when we don't have a stack trace. Also, improve
the usability of the sky_shell command line tool by defaulting to "packages"
for the package-root and not crashing when we don't have a package-root until
we actually try to load a package. Finally, remove console spam when we fail to
bind the observatory port.
Fixes#689
