hmap is a command line tool to work with Clang header maps produced by Xcode. It is written in Swift.

• Homebrew: brew install milend/taps/hmap
• Grab a release from GitHub.
• Build from source. See instructions below.

To print the contents of a header map:

hmap print ~/path/to/header_map.hmap

To convert the contents of a binary header map to JSON:

hmap convert ~/header_map.hmap ~/header_map.json

hmap deduces file formats by looking at the file extensions of the paths.

You can also use the convert command to create a binary header map from JSON:

hmap convert ~/header_map.json ~/header_map.hmap

You can discover all the commands and options by using hmap --help.

Before building with Xcode, you must download all dependencies by running:

swift package update

Then generate an Xcode project by running:

swift package generate-xcodeproj

If you would like to build from the command line, run:

swift build

To produce a release build suitable for distribution, run:

swift build -c release -Xswiftc -static-stdlib

To verify that all tests pass, run:

swift test
