halcanary e0c64c5846 Documentation: clean up

-   /user/quick/desktop to bring together all common information for
    using Skia on desktop OSes.  Remove duplication.

-   Replace all instances of call ing gyp_skia directly with calling
    `python bin/sync-and-gyp`.  This is more correct on Windows

-   Remove outdated linux prerequisite packages

-   Formatting, formatting, formatting.

-   Note command-line syntax differences in Windows

-   SampleApp.app is no longer a bundle on MacOS

Mac OS X

Quickstart

First, install XCode.

# Install depot tools.
git clone 'https://chromium.googlesource.com/chromium/tools/depot_tools.git'
export PATH="${PWD}/depot_tools:${PATH}"

# Get Skia.
git clone 'https://skia.googlesource.com/skia'
cd skia

# Build.
bin/sync-and-gyp
ninja -C out/Debug

# Run DM (the Skia test app) and SampleApp.
out/Debug/dm
out/Debug/SampleApp

Prerequisites

Make sure the following have been installed:

XCode (Apple's development environment): required
- publicly available at http://developer.apple.com/xcode/
- add the optional Unix Tools to the install so you get the make command line tool.
Chromium depot_tools: required to download the source and dependencies
- http://www.chromium.org/developers/how-tos/depottools

Check out the source code

Follow the instructions here for downloading the Skia source.

Generate XCode projects

We use the open-source gyp tool to generate XCode projects (and analogous build scripts on other platforms) from our multiplatform "gyp" files.

Two Gyp generators are used on Mac OS:

ninja - Run ninja yourself, without XCode project files,
xcode - Generate a XCode project

To choose which ones to use, set the GYP_GENERATORS environment variable to a comma-delimited list of generators before running sync-and-gyp. The default value for GYP_GENERATORS is ninja,xcode. For example to enable

Before building, make sure that gyp knows to create an XCode project or ninja build files. If you leave GYP_GENERATORS undefined it will assume the following default:

GYP_GENERATORS="ninja,xcode"

Or you can set it to ninja or xcode alone, if you like.

You can then generate the Xcode projects and ninja build files by running:

python bin/sync-and-gyp

Build and run tests from the command line

ninja -C out/Debug dm
out/Debug/dm

Build and run SampleApp in the XCode IDE

Run sync-and-gyp as described above.
In the Finder, navigate to $SKIA_INSTALLDIR/trunk/out/gyp
Double-click SampleApp.xcodeproj ; this will launch XCode and open the SampleApp project
Click the “Build and Run” button in the top toolbar
Once the build is complete, you should see a window with lots of shaded text examples. To move through the sample app, use the following keypresses:
- right- and left-arrow keys: cycle through different test pages
- 'D' key: cycle through rendering methods for each test page
- other keys are defined in SampleApp.cpp’s SampleWindow::onHandleKey() and SampleWindow::onHandleChar() methods
