"Clippy Lints" page forgets "Lint groups" selection

[smoelius]

Description

If you search for a Clippy lint by selecting one or more "Lint groups," click "View Source," and then click the back button, the lint groups will still be selected, but the selection will not be respected.

What I did:

1. Go to the Clippy Lints page.
2. Unselect all "Lint groups" but "Restriction."
3. Expand "indexing_slicing."
4. Click "View Source."
5. Click the browser back button.

What I saw: more than just "Restriction" lints.

What I expected to see: just "Restriction" lints.

In fact, after clicking the back button, if you select and unselect a lint group, you can see those lints disappearing from the listing.

Clicking "Related Issues" seems to exhibit the same behavior.

I was considering cc-ing you, @xFrednet. Do you know what is required to fix this?

Nice, I really like the lint list, thanks for the thought. 🙃

Yes, the implementation simply has to store the selection in localstorage and retrieve it once the website loads. This is already done for the theme.

Here is the complete snippet The important lines are:

• 607 as that stores the actual value
• 613 as that loads the theme on page load

It's a bit hacky as I'm a novice with JS and angular.js, but it works fairly well. You can use the same approach if you want 🙃. You are welcome to ping me for the review or any questions or just if you think something could be interesting to me 🙃

Side note: we might merge #8070 soon (I just asked if we want to merge it ^^). That might cause some conflict, but those should be simple to solve, or you base your branch on that PR 🙃

I can't reproduce this in Firefox. Either it's already been fixed or isn't an issue on some browsers.

[xFrednet]

I can reproduce it on my Firefox (99.0b7 (64-bit)). I simply open the lint list change the group selection (Just select or deselect something).

When I reload the page the selection is reset to the default.

Your browser might cache the website but even that shouldn't effect this behavior as it's a static site 🤔

I too still see the problem with Chrome Version 99.0.4844.82 (Official Build) snap (64-bit).

But thank you for checking @pitaj. 🙏

@xFrednet Reloading the page will reset it, but viewing the source then hitting back seems to be cached by Firefox, at least on my end.

Interesting :), if you want you can claim the issue. Note that this only involve JavaScript changes and nothing written in Rust 🙃

How do people feel about storing "Lint levels", "Lint groups", "Version", and perhaps the "Filter" value in the URL parameters?

Unlike theme, I personally don't expect the filters to retain their status if I were to leave the page entirely and come back. It seems like localStorage would have that sort of behavior, if I understand correctly.

Putting them in the URL parameters lets you share the settings with others, bookmark them, and solves the forward-back problem.

IMHO, your idea is a good one, @whee.
