Binaries in -moduledocs are silently swallowed #10901
Description
Describe the bug
Using binaries or sigils in -moduledoc is silently swallowed and only produces none in doc chunks. This is inconsistent with the -doc attribute which accept all forms of strings.
The documentation doesn't really specify the allowed format but mentions the word "string" a few times.
This took a long while to debug after discovering that ex_doc didn't add my module descriptions 😅
To Reproduce
| Format | -moduledoc |
-doc |
|---|---|---|
"string" |
✅ works | ✅ works |
"""triple""" |
✅ works | ✅ works |
<<"binary">> |
none |
✅ works |
~"sigil" |
none |
✅ works |
~"""triple""" |
none |
✅ works |
Expected behavior
All formats work everywhere. Or at least an error if the format is not allowed.
