Internal links to README.md are broken

[lily-commure]

README.md gets translated to index.html, but internal links (except for those in SUMMARY.md) don't get translated. So they point to a non-existent README.html path. mdBook should either generate both index.html and README.html or translate internal links so that they point to index.html instead.

Ok, here's an example:
If you want to add a link to some page, you can type [Some page](some_dir/some_page.md), but if you try to link README this way, the link will be broken.

Repro steps

docker run -it --rm rust:slim bash
# cargo install mdbook
# mkdir /app
# cd /app
# mdbook init
...
# printf "[Test](./test/README.md)\n[Test 2](./test.md)" > src/SUMMARY.md
# printf "[Test](./test/README.md)" > src/test.md
# mkdir src/test
# printf "# Test" > src/test/README.md
# mdbook build
# cat book/test.html | grep README.html
<p><a href="./test/README.html">Test</a></p>
# ls book/test
index.html

duplicated issue? #1268

[ehuss]

Yea, both issues are essentially the same. I'll keep this one, but there is some more context and discussion in #1268 that is worth reading.

So what's the latest on this? I'm just seeing a circular loop of duplicate_of's and closed Issues that don't seem to go anywhere. Is there a way to resolve this currently?

@umdstu You can upvote #1921

Just in case anybody stumbles upon the same issue:

We use this one line in our ci script using find and sed (with extended regular expressions support):

find $MD_BOOK_ROOT/src/ -type f -name "*.md" ! -iname "SUMMARY.md" -exec sed -ri 's/(\[.*\])\((.*\/)?(readme\.md)(#.*)?\)/\1\(\2index\.md\4\)/gI' {} \;

Looks funky, but it just works :)

Opinion: Mapping README.md to index.html seems fine, however if that is done then I think any links to README.md also need to be handled. The options seem to be:

• Update the links
• Include a README.html in the output that is a copy of index.html or that redirects to index.html

Any update? 😥
