This will allow to make use of func (*Reader) Seek, instead of re-recreating a
new reader. It's a large commit for a small change, but anything to simply the
reader/buffer/ReadAll/… mess is a step in the right direction I think, and it
should enable more follow-up simplifications.
- allow youtube urls to start with `www`
- use `strings.Builder` instead of a `bytes.Buffer`
- use a `strings.NewReader` instead of a `bytes.NewBufferString`
- sprinkles a couple of `continue` to make the code-flow more obvious
- inline calls to `inList`, and put their parameters in the right order
- simplify isPixelTracker
- simplify `isValidIframeSource`, by extracting the hostname and comparing it
directly, instead of using the full url and checking if it starts with
multiple variations of the same one (`//`, `http:`, `https://` multiplied by
``/`www.`)
- add a benchmark
There is no need to do extra work like creating a session and its associated
view until the user has been properly identified and as many possibly-failing sql request have been successfully run.
- Reduce the amount of nested loops: it's preferable to search the whole page
once and filter on it (even with filters that should always be false),
than searching it again for every element we're looking for.
- Factorize the proxying conditions into a `shouldProxy` function to reduce the
copy-pasta.
- Refactorise the tests and add some
- Use 250 signs instead of the whole text
- Only check for Korean, Chinese and Japanese script
- Add a benchmark
- Use a more idiomatic control flow

If the user doesn't display reading times, there is no need to compute them.
This should speed things up a bit, since `whatlanggo.Detect` is abysmally slow.
Instead of having to allocate a ~100 keys map containing possibly dynamic
values (at least to the go compiler), allocate it once in a global variable.
This significantly speeds things up, by reducing the garbage
collector/allocator involvements.
Local synthetic benchmarks have shown a improvements from 38% of wall time to only
12%.
- `make([]a, b)` create a slice of `b` elements `a`
- `make([]a, b, c)` create a slice of `0` elements `a`, but reserve space for `c` of them
When using `append` on the former, it will result on a slice with `b` leading
elements, which is unlikely to be what we want. This commit replaces the two
instances where this happens with the latter construct.
Go 1.22 introduced a new [for-range](https://go.dev/ref/spec#For_range)
construct that looks a tad better than the usual `for i := 0; i < N; i++`
construct. I also tool the liberty of replacing some
`for i := 0; i < len(myitemsarray); i++ { … myitemsarray[i] …}`
with `for item := range myitemsarray` when `myitemsarray` contains only pointers.
- Use a simple regex to parse data uri instead of a hand-rolled parser, and
document what fields are considered mandatory.
- Use case-insensitive matching to find (fav)icons, instead of doing the same
query twice with different letter cases
- Add 'apple-touch-icon-precomposed.png' as a fallback favicon
- Reorder the queries to have i`con` first, since it seems to be the most
popular one. It used to be last, meaning that pages had to be parsed
completely 4 times, instead of one now.
- Minor factorisation in findIconURLsFromHTMLDocument
- Split dates formats into those that require local times
and those who don't, so that there is no need to have a switch-case in the
for loop with around 250 iterations at most.
- Be more strict when it comes to timezones, previously invalid ones like -13
were accepted. Also add a test for this.
- Bail out early if the date is an empty string.
- make findContentUsingCustomRules' more idiomatic,
since in golang a function returning an error might
return garbage in other parameter. Moreover, ignoring
errors is bad practise.
- getPredefinedScraperRules is now running in constant-time,
instead of iterating on a list with around 50 items in it.
- Surface `localizedError` in FindSubscriptionsFromWellKnownURLs via slog
- Use an inline declaration for new subscriptions, like done elsewhere in the
file, if only for consistency's sake
- Preallocate the `subscriptions` slice when using an RSS-bridge,
it's a good practise, and it might even marginally improve
performances when adding __a lot__ of feeds via an rss-bridge instance, wooo!
- `NOT (hash=ANY(%4))` can be expressed as `hash NOT IN $4`
- There is no need for a subquery operating on the same table,
moving the conditions out is equivalent.
No need for a `BETWEEN`: we want to filter on entries published in the last
week, no need to express is as "entries published between now and last week",
"entries published after last week" is enough.
- Use constant time access for maps instead of iterating on them
- Build a ~large whitelist map inline instead of constructing it item by item
(and remove a duplicate key/value pair)
- Use `slices` instead of hand-rolled loops
There are a few things that need to be done, to make this work.
First, we need to register `Enter` as another hotkey that opens the
selected item.
However, by default the `KeyboardHandler` will override all default
actions. That might make sense for any other key, but for the `Enter`
key, we want to keep the default behavior (i.e. follow a selected link
or press a button). So for this single key event, we do not call
`preventDefault()`.
I see this as unproblematic for the following reasons.
1. With the changes from #2348, when we're in a list of items (articles,
categories, feeds), there is no link selected. This is what made the
`Enter` key work _implicitly_ in the past. With nothing selected, the
`Enter` key will do nothing by default.
2. If we have **any** link selected (including when we are in a view
with a list of selectable items), we'll get the default action of
`Enter` (i.e. follow a link), which is exactly what we had before.
Lastly, we need to update the list of keyboard shortcuts displayed when
pressing `?`.
This fixes#2366.
# Change HTML tag to button
Replace the link tag with an HTML button to prevent some screen readers from having confusing announcements. By using the HTML button, users can use the Enter and Space keys to activate actions by default, instead of implementing them in JavaScript.
# Differentiate links and buttons visually
When activating the link element, the user may expect the web page to navigate to the URL and the page will refresh; when activating the button element, the user may expect the web page to still be on the same page, so that their current state, such as: input value, won't disappear.
Links and buttons should have different styles visually, so that users can't expect what will happen when they activate a link or a button.
I added the underline to the links, because that is the common pattern. Buttons have border and background color in a common pattern. But I think that will change the current layout drastically. So I added the focus, hover and active classes to the buttons instead.
