能否指定已解压的FHIR包目录运行IG Publisher工具？

Absolutely! This approach is completely feasible and is a smart optimization to cut out the repetitive 1-2 minute decompression step—you’re totally right that the static FHIR package files don’t need unpacking every time you run the publisher.

Here’s how to implement this smoothly:

1. Manually extract the package.tgz file first
   Use your system’s built-in tools or a utility to unpack the archive into a dedicated directory. For Unix-like systems (Linux/macOS), run this command:

   tar -xzf package.tgz -C ./package/
   

   On Windows, you can use tools like 7-Zip to extract the contents into a folder named package in your working directory.

2. Update your IG Publisher command
   Replace the -spec package.tgz argument with the path to your extracted directory. Your command will look like this:

   java -jar org.hl7.fhir.igpublisher.jar -spec ./package/ -ig ig.json
   

3. Verify the setup
   Run the updated command and confirm your static documentation generates correctly. It should produce identical output to when you used the .tgz file, but with a much faster start time.

A few key notes to keep in mind:

• Keep the extracted directory’s full structure intact—don’t delete or modify any files inside. The IG Publisher depends on the complete set of FHIR specification resources and metadata files.
• When you need to update to a newer FHIR STU3 version, re-download the corresponding package.tgz and extract it over your existing package directory (avoid patching individual files).
• Ensure the path you pass to -spec points to the root of the extracted package (where the package.json file resides)—this is required for the publisher to locate all resources correctly.
