[libc++][ranges][NFC] Revamp the Ranges status page

[var-const]

Summary

Focus on the not-yet-implemented features: remove most details about the
already-implemented C++20 stuff, list out the major C++23 additions.

[var-const]

Remove old status page

Do we need that separate page? Can't we track those using the normal C++20/C++23 issues page?

Same here -- why don't we track that from the C++20/C++23 papers page instead?

[Mordante]

Thanks for improving the status pages!

This will be a merge conflict, the status is partial https://libcxx.llvm.org/Status/Cxx2b.html

We indeed removed issues from the status pages in the past. I don't mind to keep them. Looking at the huge list of issues I can imagine tracking them on one page is easier; even when it duplicates entries. (Something tells me C++26 will add new LWG issues for ranges.)

This is not true; parts have already landed ;-) I already track this on the format status page. (https://libcxx.llvm.org/Status/Format.html)

Drive-by comments for consistency

It might also be worth to linkify all those papers (as done elsewhere)

206

Always been mildly bothered by this inconsistency.

Missing ,"" at the end (might work without it, but still cleaner to have right number of columns)

[var-const]

Address feedback, fix build issues, add some missing links

Agreed, but I'd rather do it in a separate patch and keep this focused on Ranges. (Or feel free to send in the patch if you'd like)

206

Same -- agreed this should be fixed, but I'd rather keep this patch smaller. Would you like to do a patch with the fixes you mentioned? I can help you with generating the docs to check the change locally.

libcxx/docs/Status/Cxx2bIssues.csv

37

Thanks!

76

I'm not sure -- the existing formatting seems to always have an empty column for the status row and the first released version raw, but not for the label row. I followed that for consistency, but I presume either works.

libcxx/docs/Status/Cxx2bPapers.csv

Thanks! Should I add you as an assignee on this in the RangesMajorFeatures.csv list? (it's primarily to make sure we don't accidentally duplicate work)

Honestly, I'm torn about this. Neither keeping two large lists in sync (when they are almost guaranteed to diverge) nor having to scoop around a huge list of papers searching for a certain tag seems great. I wish it were possible to import only a subset of a CSV table, filtered by a tag, but I'd be surprised if it were a supported option.

After discussing this with @ldionne, I decided to drop the duplication. IIUC, we will switch to using GitHub issues to track these at some point, so ultimately it's not super important how we approach this.

Removed now.

This is great! And thank you for the heads-up.

+1 for doing this in GitHub

I recall we discussed that in the past but it required GitHub projects to be enabled for LLVM.

libcxx/docs/Status/Cxx2bPapers.csv

Yes please assign it to me.

[var-const]

Update the status of in-progress items.

[Mordante]

LGTM, I leave the final approval for another reviewer.

I'm also +1 for using GitHub issues to track the work instead. It has a lot of benefits, including visibility for external contributors who may not be aware of the status pages.
