Rime with Mac

Preparation

Install Xcode with command line tools.

Install other build tools:

brew install cmake git

Get the code

git clone --recursive https://github.com/rime/librime.git

or download from GitHub, then get code for third-party dependencies separately.

Install Boost C++ libraries

Boost is a third-party library which librime code heavily depend on. These dependencies include a few compiled (non-header-only) Boost libraries.

Option 1 (recommended): Download and build Boost from source.

cd librime
make xcode/deps/boost

The make script will download Boost source tarball, extract it to librime/deps/boost_<version> and create needed static libraries for building macOS uinversal binary.

Set shell variable BOOST_ROOT to the path to boost_<version> directory prior to building librime.

export BOOST_ROOT="$(pwd)/deps/boost_1_78_0"

Option 2: Install Boost libraries from Homebrew.

brew install boost
# to build with icu4c, add the icu4c install path to LIBRARY_PATH
export LIBRARY_PATH=${LIBRARY_PATH}:/opt/homebrew/opt/icu4c/lib:/usr/local/opt/icu4c/lib

This is a time-saving option if you are building and installing Rime only for your own Mac computer.

Built with Homebrewed version of Boost, the librime binary will not be portable to machines without certain Homebrew formulae installed.

Option 3: Install an older version of Boost libraries from Homebrew.

Starting from version 1.68, boost::locale library from Homebrew depends on icu4c, which is not provided by macOS.

Make target xcode/release-with-icu tells cmake to link to ICU libraries installed locally with Homebrew. This is only required if building with the librime-charcode plugin.

To make a portable build with this plugin, install an earlier version of boost that wasn't dependent on icu4c:

brew install [email protected]
brew link --force [email protected]

Build third-party libraries

Required third-party libraries other than Boost are included as git submodules:

# cd librime

# if you didn't checked out the submodules with git clone --recursive, now do:
# git submodule update --init

make xcode/deps

This builds libraries located at librime/deps/*, and installs the build artifacts to librime/include, librime/lib and librime/bin.

You can also build an individual library, eg. opencc, with:

make xcode/deps/opencc

Build librime

make xcode

This creates build/lib/Release/librime*.dylib and command line tools build/bin/Release/rime_*.

Or, create a debug build:

make xcode/debug

Run unit tests

make xcode/test

Or, test the debug build:

make xcode/test-debug

Try it in the console

(
  cd debug/bin;
  echo "congmingdeRime{space}shurufa" | Debug/rime_api_console
)

Use it as REPL, quit with Control+d:

(cd debug/bin; ./Debug/rime_api_console)
