Qualify pegged/peg.d as @safe and when possible pure nothrow @nogc

./ci.sh passes for me on Ubuntu 20.04 now, @John-Colvin.

[veelo]

Thanks for doing this!

It seems to me that the CI failures are due to deficiencies in moderately recent (2 years old) druntime.

I am thinking of determining the release at which this starts working a bit more precisely, putting that in a toolchainRequirements section, and releasing this with a mayor version bump. Would that work for Symmetry @John-Colvin? What is the oldest D frontend release that you depend on?

Yes, specifically when AA.keys being @system. I've added some versioning to solve some of them at 9fb4d41.
I doubt we are in need of supporting a pre-2.091 toolchain. Right @John-Colvin? If so I can remove the versioning I just added at 9fb4d41.

[nordlow]

Hitting 2.091-version compiler bugs aswell at https://ci.appveyor.com/project/PhilippeSigaud/pegged/builds/43483820/job/3503ke4jawrotjej#L83.

[John-Colvin]

We only care about the compilers we actively support (@nordlow the ones our setup scripts install)

[nordlow]

CI is green now. In appveyor.yml, I suggest removing support for dmd 2.087.1 and bump 2.090.1 to 2.091.0 having @safe AA.keys which avoids the need for the versioning added at 9fb4d41.

The oldest compiler version "we" need support for is version 2.099.1. So to which compiler version less or equal to <= 2.099.1 do you want to bump matrix-entries in appveyor.yml to, @veelo?

[veelo]

Can you please react to #311 (comment)? I think it fits into this PR. If you don't want to do it then that's fine, and I'll see if I can do a follow-up PR.

Sorry, missed that. I'll have look.

I think we should try to support as far back as we reasonably can, so like you suggest:

removing support for dmd 2.087.1 and bump 2.090.1 to 2.091.0

but then also make that explicit with a toolchainRequirements section section in the Dub configuration.

I'll have to think about whether that demands a major version bump, since technically that would brake the build for people that don't update their compiler regularly. I'll ask the forum.

[nordlow]

Correction: AA.keys() became @safe version in 2.098.0 as per https://dlang.org/changelog/2.098.0.html#bugfix-list referencing https://issues.dlang.org/show_bug.cgi?id=14439. Gonna update.

[veelo]

I'll ask the forum.

I cannot release this yet, since parser.d is a generated parser (Pegged generates its own parser). Whenever parser.d is regenerated, the @safe annotations will be reverted from it. Pegged will need to be modified to generate @safe parsers.

I really need to review the CI so that this is covered in the future.

Can you give me a sample command line call that does this? Then I can dig into having the generated parser be @safe as well.

[veelo]

It is in https://github.com/PhilippeSigaud/Pegged/tree/master/pegged/dev. But that doesn't work anymore because I have accepted too many PRs that weren't sound :-(
The command is currently

cd pegged/dev
rdmd -I../.. -I../../examples/peggedgrammar/src -I../../examples/misc/src regenerate.d

but that reverses some changes from some earlier PRs. It's a mess.

If you are waiting for this, I can tag a new release in the mean time while I clean this up. It has been this way since a few releases. Would a beta work for you?

https://github.com/PhilippeSigaud/Pegged/releases/tag/v0.4.6

Awesome! Thank you!

Is there anything more you need help with?

[nordlow]

Can you please bump https://code.dlang.org/packages/pegged tag aswell to 0.4.6? It's still at 0.4.5.

[veelo]

Is there anything more you need help with?

Seriously? There is a lot to do actually, but most of it requires a deeper dive. We can talk about those if you are interested.

Otherwise, I'd really like an automated check on PRs to make sure the committed parser.d is the same as one that is generated.

[veelo]

Can you please bump https://code.dlang.org/packages/pegged tag aswell to 0.4.6? It's still at 0.4.5.

To my knowledge, it should update automatically. It probably scans for new tags every so many hours.

Still no bump to 0.4.6 at https://code.dlang.org/packages/pegged. Can you bump it yourself, please? Are you the only one who has permissions to do so? FYI, @skoppe.

[veelo]

No, I don't even have an account. I think that one is still with @PhilippeSigaud. I am wondering if it is because the other releases have a commit signature icon, but I don't know why the latest doesn't.

Do you have any clues as to why, @John-Colvin @skoppe?

[veelo]

I don't think the signature has anything to do with it, other packages that did update in the Dub registry within the last 16 hours don't have that icon either. I've checked the syntax of the tag multiple times, should be no problems there. I made sure that the pre-release checkbox is unchecked. The Dub docs say that tags are scanned about twice an hour. This is not my first release, and I don't think I did anything different from last time.

[CyberShadow]

I remember that the updater used to sometimes get stuck. Sonke would come in and restart it. However, I just tried to update my own package and it succeeded, so I don't think it's that in this case. It seems to have trouble with this specific package.

A package admin could go to https://code.dlang.org/my_packages/pegged and perhaps that page would show an error message.

@s-ludwig Seems that we need your help again; also, if there's anyone else who could help here, perhaps they should be listed on https://wiki.dlang.org/People#Points_of_contact .

Further note that https://github.com/PhilippeSigaud has been inactive for at least one year.

[veelo]

Maybe it's time to transfer Pegged to https://github.com/dlang-community? I'm fine with continuing as a maintainer of Pegged. At least then there is a group of people that are able to pick up the ball it case it is dropped. Is there a shared dub account for those projects? What is the procedure for such a transfer?

I vote for that. Ping, @John-Colvin @RazvanN7.

[skoppe]

Yes, I have had this happen repeatably the last year. Sometimes it works, sometimes it doesn't. The page says its processing, but nothing happens (for days) unless I manually hit the button, all the while other packages are just updating.

[veelo]

It finally got through now.

[nordlow]

Thank you. Was it thanks to somebody manually refreshing the tag on code.dlang.org?

Don't know. There was an issue with an expired certificate, but I doubt it is related because other packages had no issue.
