There are a couple of dependencies required to build Lime on macOS.
Homebrew
Homebrew (often referred as just brew to resemble its command) is a package manager for macOS. This page details how you can install Homebrew. Make sure to run brew doctor before installing anything.
Installing dependencies
Once Homebrew is installed, install the following dependencies:
brew install pkg-config go mercurial oniguruma python3 qt5
Before building you will need to add the python3 and qt5 paths to your PKG_CONFIG_PATH:
export PKG_CONFIG_PATH=$(brew --prefix python3)/Frameworks/Python.framework/Versions/3.4/lib/pkgconfig:$(brew --prefix qt5)/lib/pkgconfig:$(brew --prefix oniguruma)/lib/pkgconfig
Note that (as of January 26, 2018) brew install python3 installs Python 3.6.
But https://github.com/limetext/gopy seems to require Python 3.5.
This StackOverflow question shows a way to install Python 3.5: https://apple.stackexchange.com/questions/237430/how-to-install-specific-version-of-python-on-os-x Via this command: brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/ec545d45d4512ace3570782283df4ecda6bb0044/Formula/python3.rb
All external dependencies are now installed. Continue on to the instructions on the Building page.
Troubleshooting
If you have problems installing python3 try downloading the .dmg instead:
For macOS 10.6 or later:
curl -O https://www.python.org/ftp/python/3.4.1/python-3.4.1-macosx10.6.dmg
For macOS 10.5:
curl -O https://www.python.org/ftp/python/3.4.1/python-3.4.1-macosx10.5.dmg
Missing GoPath
If you get the error:
package github.com/limetext/lime-backend/lib/...: cannot download, $GOPATH not set. For more details see: go help gopath
Set a GoPath
mkdir ~/.gopath; export GOPATH=~/.gopath
