0.13.0 release planning

[djc]

We've accumulated quite a bunch of stuff, and should probably release some time soon.

Any thoughts on open issues/PRs (especially changes that affect the public API/behavior) that shouldn't miss the 0.13.0 release?

Here are some open PRs that I think should go in:

• Clean up features #1001
• Make JSON prettifying optional #1023
• Fix nested templates block #1029
• Test partial renders with block fragments #1032
• if let chain has a weird behaviour #1033
• Fix block partial rendering #1054
• Reproduce bug #1075: rendering nested block broken by if-else-endif i… #1080

Agreed. It'd be nice to have the book situation fixed too at some point.

I am using Askama in my project, and I am very satisfied with it. I have reviewed and used various frameworks, but there was no tool as concise and intuitive as Askama. Please continue to give it your attention. Thank you.

hi, i used askama in a rewrite form java spring boot with thymeleaf, and i liked it allot. the only feature that would make it even nicer for me is nested templates blocks. one other thing that i noticed and it would be nice if it got fixed is error reporting, it would be nice if the errors show more context about the template file and the line number as an example.

in general i really enjoyed working with askama, and i'm looking forward for the 0.13 release.

It would be nice to get block fragment rendering released. 🙏

There was a PR or discussion about using Darling a while back. The error message is more descriptive about what the problem is: Ex:

error: Unknown field: `block`
  --> test-darling/src/main.rs:11:29
   |
11 | #[template(path="foo.html", block=bar)]
   |                             ^^^^^

compared with the current error message:

unsupported attribute key Ident { ident: "block", span: #0 bytes(16214..16219) } found

Would this be worth revisiting for better error handling?

Already fixed in the current rinja version: https://rinja-rs.github.io/play-rinja/?saved=eJwrM4wxUI4uSc0tyEksSdVIrShRsFVQyijJzVHSUUjKyU_OBvKTEos0Y7mKS4pKk0sUQqxjDADnzRF2, which will become the next askama release.

My point wasn't about the block attribute being unsupported. I'm aware that that is fixed in the unreleased 0.13 version.

My point was that any error message in Askama caused by a misconfiguration leads to an error message which takes longer to diagnose than it should. That can be as simple as a typo in an attribute (blocks vs block), an extra punctuation character (path == "foo.html") or any sort of thing.

[Kijewski]

I know, and the error message for unknown attributes is good now. Click the link.

[joshka]

Ah - ok, so there's code which isn't anywhere in this repo which is tested in another repo? Any chance you can expand on what's happening with the reunification with rinja? I don't see any discussion / issue / info about it anywhere.

[Kijewski]

Yeah, we should really do that. Right now it's handled kinda behind the scenes between @djc, @GuillaumeGomez, and me.

Short answer: We have only a few PRs that need to be fixed, then the current rinja master will become askama 0.13, and the rinja crate will get a message that it's deprecated in favor of askama. But please don't expect any of that to happen in this year, though.

[joshka]

Sounds like a good idea that would be positive for the project's health. Looking forward to it :)
