Summary

Successfully updated mdbook-embedify from mdbook 0.4.51 to 0.5.2 compatibility. All tests pass, code review is clean, no security vulnerabilities detected.

Fixed CI issues:

1. Workflows now check installed mdbook version and reinstall if it doesn't match required version (0.5.2)
2. Test book.toml now uses correct relative path (../../target/release/mdbook-embedify) since mdbook 0.5.x changes working directory to the book root before executing preprocessors

Original prompt

Fix the issue that it doesn't compatible with mdbook version 0.5.x, currently project using mdbook version 0.4.c

@copilot will the built binary supports mdbook version 0.4.x

@copilot will the built binary supports mdbook version 0.4.x

No, the built binary will only support mdbook 0.5.x.

The preprocessor is compiled against mdbook 0.5.x types (mdbook-preprocessor and mdbook-core), which have different APIs and potentially different JSON serialization formats compared to 0.4.x. Running this binary with mdbook 0.4.x would likely result in deserialization errors or incompatible behavior.

Users will need to upgrade their mdbook installation to 0.5.x to use this version of mdbook-embedify. If they need to stay on mdbook 0.4.x, they should use an older version of mdbook-embedify (0.2.18 or earlier with the previous dependency on mdbook = "0.4.51").

Fixed in commit 8a33945. The CI workflows were trying to extract the mdbook version using grep '^mdbook' which no longer matches since we changed to mdbook-core and mdbook-preprocessor. Updated both workflows to use grep '^mdbook-core' to correctly extract the version (0.5.2) for installing the mdbook binary.

Could you provide more details about what's failing? The changes I made should:

1. Extract version "0.5.2" from mdbook-core dependency
2. Install mdbook CLI tool version 0.5.2
3. Run tests which require mdbook

Is the issue:

• The version extraction not working?
• The mdbook installation failing?
• A specific test failing?
• Something else?

If you have CI logs or error messages, that would help me fix the issue more quickly.

Fixed in commit 0e39e54. The issue was that CI was using a cached mdbook 0.4.x installation, but the preprocessor was compiled against mdbook 0.5.x types. This caused a JSON deserialization error: "missing field items" because the Book structure changed between versions.

The workflows now:

1. Extract the required version from mdbook-core dependency (0.5.2)
2. Check if mdbook is installed and compare versions
3. Reinstall mdbook 0.5.2 if the installed version doesn't match

This ensures the mdbook binary and preprocessor are always compatible.

Fixed in commit 0e28638. The issue was that mdbook 0.5.x changes its working directory to the book root before executing preprocessors, so the relative path target/release/mdbook-embedify in book.toml was looking for the binary in the wrong location (tests/test-book/target/release/mdbook-embedify instead of ./target/release/mdbook-embedify).

Changed the path to ../../target/release/mdbook-embedify to correctly reference the binary from the test book directory.
