This should handle over-long lines. I had tried to make the normalize method work, but it doesn't seem promising and so let's at least enable this version. Assisted-by: Antigravity with Gemini

|
## Background
|
|
|
|
The [language design](/docs/design) documentation in the Carbon project should
|
|
use a consistent style and tone, and should read as if it were written by a
|
|
single author. This document describes structural, stylistic, and formatting
|
|
conventions for the language design, where they have been established.
|
|
|
|
## General
|
|
|
|
The language design documentation follows the
|
|
[style conventions](/CONTRIBUTING.md#google-docs-and-markdown) for Carbon
|
|
documentation.
|
|
|
|
## Linking
|
|
|
|
- Links to issues and to complete proposals should use the text `#nnnn`, where
|
|
`nnnn` is the issue number, optionally followed by the proposal title, and
|
|
should link to the issue or pull request on GitHub. For example, `[#123:
|
|
widget painting](https://github.com/carbon-language/carbon-lang/pull/123)`.
|
|
- Links to specific sections of a proposal should link to the repository copy
|
|
of the proposal file, using the section title or other appropriate link
|
|
text. For example,
|
|
`[Painting details](/proposals/p000123-bikeshed-design.md#painting-details)`
|
|
|
|
## Document structure
|
|
|
|
Documents within the language design should usually be divided into the
|
|
following sections, with suitable level-two (`##`) headings:
|
|
|
|
- **Table of contents** (auto-generated)
|
|
- **TODO** (optional)
|
|
- **Overview**
|
|
- Zero or more detailed design sections
|
|
- **Alternatives considered**
|
|
- **References**
|
|
|
|
### Overview and detailed design
|
|
|
|
The overview should describe the high-level concepts of this area of the design,
|
|
following BLUF principles. Where the overview does not fully cover the detailed
|
|
design, additional sections can be added as needed to more completely describe
|
|
the design.
|
|
|
|
The aim of these sections is to describe the design choices that have been made,
|
|
how those choices fit into the overall design of Carbon, the rationale for those
|
|
choices, and how and why those choices differ from other languages to which
|
|
Carbon is likely to be compared, particularly C++, Rust, and Swift.
|
|
|
|
### Alternatives considered
|
|
|
|
This section should provide bullet points briefly describing alternative designs
|
|
that were considered, along with references to the proposals in which those
|
|
designs were discussed. For example:
|
|
|
|
```md
|
|
- [Paint widgets from bottom to top](/proposals/p000123-bikeshed-design.md#alternatives-considered).
|
|
```
|
|
|
|
### References
|
|
|
|
This section should provide bullet points linking to the following:
|
|
|
|
- External documents providing background on the topic or additional useful
|
|
information.
|
|
- Each proposal that contributed to the design described in this document.
|
|
|
|
For example:
|
|
|
|
```md
|
|
- [Wikipedia example page](https://en.wikipedia.org/wiki/Wikipedia:Example)
|
|
- Proposal
|
|
[#123: widget painting](https://github.com/carbon-language/carbon-lang/pull/123).
|
|
```
|
|
|
|
Links to related parts of the design should be included inline, where relevant,
|
|
not in the references section.
