ERA001 stops parsing an inline script metadata block at the first # /// line

[dscorbett]

ERA001 skips PEP 723 inline script metadata blocks as of #10455, except that it stops skipping after the first # /// line. However, a metadata block continues if the following lines are valid embedded content followed by another # /// line. ERA001 should skip over the full metadata block.

For example, this script (named era001.py) contains metadata with an embedded # /// line.

# /// script
# [tool.uv]
# extra-index-url = ["https://pypi.org/simple", """\
# https://example.com/
# ///
# """
# ]
# ///
print(1)

The script works, which shows that the first # /// line does not end the block. (I am using uv, but this could work with any tool that interprets inline metadata.)

$ uv version
uv 0.4.7 (a178051e8 2024-09-07)
$ uv run era001.py
Reading inline script metadata from: era001.py

However, Ruff reports an error.

$ ruff --version
ruff 0.6.4
$ ruff check --isolated --select ERA001 era001.py

Thanks. From the PEP:

Precedence for an ending line # /// is given when the next line is not a valid embedded content line as described above. For example, the following is a single fully valid block:

# /// some-toml
# embedded-csharp = """
# /// <summary>
# /// text
# ///
# /// </summary>
# public class MyClass { }
# """
# ///
