[lex] Provide unicode name for all control characters #7404
Conversation
|
Note that I also did a review of all usage of the word "space" in [lex] and [cpp]. Some uses were not relevant, such as "name space". Others applied to the contents of literals, which might not be in the basic source encoding. This PR is considered to completely address the concern for control characters throughout the standard. |

I don't think plural works for the way we present Unicode chars. Please rephrase.
Also, we seem to use "new-line" elsewhere (e.g. near the changes above). Note the hyphen.

I specifically copied newlines from the original list, as I had seen both terms in the standard. Now the I search again, there are only 4 remaining, and half are in code comments. I will fix this one here, and file a separate PR to fix the rest.

Rewording for plurals attempted.

And it turns out the remaining three uses of "newline" are all in library clauses, which outnumber the one use of "new-line" in the library, so I will defer that question for now. The fix for new-line above is now in this PR though.

This commit does not touch the new-line character as paper P2348. It resricts itself to consistent use of the unicode character name for space, horizontal tab, and vertical tab. Compared to PR cplusplus#7359 it deliberately does not touch the grammar that would necessitate a review by core review. The intent is to rebase that PR if this one lands.
