"Part Titles" in SUMMARY.md causes mdbook-graphviz to fail #9

Closed nickdanis closed 3 years ago

nickdanis commented 3 years ago

mdbook supports markdown headings in the SUMMARY.md file as documented here: https://rust-lang.github.io/mdBook/format/summary.html

# Summary

- [Intro](./intro.md)
# Part 1
- [Chapter](./chapter.md)

When these are included in SUMMARY.md with mdbook-graphviz called in book.toml, the build fails with the following error:

Unable to parse the input
[WARN] (mdbook::preprocess::cmd): Error writing the RenderContext to the backend, The pipe is being closed. (os 
error 232)
[ERROR] (mdbook::utils): Error: The "graphviz" preprocessor exited unsuccessfully with exit code: 1 status

When either the part title is absent, or mdbook-graphviz is not called, the build succeeds as expected. This is using mdbook 0.4.10.

This was due to not supporting mdbook 0.4, you should be good now that I've published https://github.com/dylanowen/mdbook-graphviz/releases/tag/v0.1.0 with https://github.com/dylanowen/mdbook-graphviz/pull/4
