commands to all files
1. Use general "mobile-only" and "not-mobile" CSS styles, remove some`@media (max-width: 767.98px)` tricks
2. Use `CountFmt` for repo list, just like the repo header (and it matches GitHub, to avoid big numbers bloat the page)

Resolved the template conflicts by porting the changes to Forgejo (in
case of `header.tmpl`, applying the changes in `header_fork.tmpl). In
case of the CSS change, opted to take Gitea's version and drop the
entire media query.
Fixes https://github.com/go-gitea/gitea/issues/30005. Regression from
https://github.com/go-gitea/gitea/pull/29945.
There was only once instance of `tw-content-center` before that PR, so I
just ran below command and reverted that one instance.

Actually in modern days, in most cases it doesn't need such

If anyone really needs to do ReplaceAliases for some contents, I will

- Refactor the system status list into its own template
- Change the backend to return only the system status if htmx initiated
the request
- `hx-get="{{$.Link}}/system_status`: reuse the backend handler
- `hx-swap="innerHTML"`: replace the `<div>`'s innerHTML (essentially
the new template)
- `hx-trigger="every 5s"`: call every 5 seconds
- `hx-indicator=".divider"`: the `is-loading` class shouldn't be added
to the div during the request, so set it on an element it has no effect
on
- Render "Since Last GC Time" with `<relative-time>`, so we send a
timestamp

- The `<title>` element that lives inside the `<head>` element is an important element that gives browsers and search engine crawlers the title of the webpage, hence the element name. It's therefor important that this title is accurate.
- Currently there are three issues with titles on repositories. It doesn't use the `FullName` and instead only uses the repository name, this doesn't distinguish which user or organisation the repository is on. It doesn't show the full treepath in the title when visiting an file inside a directory and instead only uses the latest path in treepath. It can show the repository name twice if the `.Title` variable also included the repository name such as on the repository homepage.
- Use the repository's fullname (which include which user the repository is on) instead of just their name.
- Display the repository's fullname if it isn't already in `.Title`.
- Use the full treepath in the repository code view instead of just the
last path.
- Adds integration tests.
- Adds a new repository (`repo59`) that has 3 depths for folders, which
wasn't in any other fixture repository yet, so the full treepath for
could be properly tested.
- Resolves https://codeberg.org/forgejo/forgejo/issues/1276

- Closes https://github.com/go-gitea/gitea/issues/28880
This change introduces htmx with the hope we could use it to make Gitea
more reactive while keeping our "HTML rendered on the server" approach.
- Add `htmx.js` that imports `htmx.org` and initializes error toasts
- Place `hx-headers='{"x-csrf-token": "{{.CsrfToken}}"}'` on the
`<body>` tag so every request that htmx sends is authenticated
- Place `hx-swap="outerHTML"` on the `<body>` tag so the response of
each htmx request replaces the tag it targets (as opposed to its inner
content)
- Place `hx-push-url="false"` on the `<body>` tag so no changes to the
URL happen in `<form>` tags
- Add the `is-loading` class during request
### Error toasts in action
## Don't do a full page load when clicking the subscribe button
- Refactor the form around the subscribe button into its own template
- Use htmx to perform the form submission
- `hx-boost="true"` to prevent the default form submission behavior of a
full page load
- `hx-sync="this:replace"` to replace the current request (in case the
button is clicked again before the response is returned)
- `hx-target="this"` to replace the form tag with the new form tag
- Change the backend response to return a `<form>` tag instead of a
redirect to the issue page
### Before
### After
## Don't do a full page load when clicking the follow button
- Use htmx to perform the button request
- `hx-post="{{.ContextUser.HomeLink}}?action=follow"` to send a POST
request to follow the user
- `hx-target="#profile-avatar-card"` to target the card div for
replacement
- `hx-indicator="#profile-avatar-card"` to place the loading indicator
on the card
- Change the backend response to return a `<div>` tag (the card) instead
of a redirect to the user page

### After

In #26851, it assumed that `Commit` always exists when
`PageIsDiff==true`.
But for a 404 page, the `Commit` doesn't exist, so the following code
would cause panic because nil value can't be passed as string parameter
to `IsMultilineCommitMessage(string)` (or the StringUtils.Cut in later
PRs)
Part of https://github.com/go-gitea/gitea/issues/27097:
- `gitea` theme is renamed to `gitea-light`
- `arc-green` theme is renamed to `gitea-dark`
- `auto` theme is renamed to `gitea-auto`
I put both themes in separate CSS files, removing all colors from the
base CSS. Existing users will be migrated to the new theme names. The
dark theme recolor will follow in a separate PR.
## ⚠️ BREAKING ⚠️
1. If there are existing custom themes with the names `gitea-light` or
`gitea-dark`, rename them before this upgrade and update the `theme`
column in the `user` table for each affected user.
2. The theme in `<html>` has moved from `class="theme-name"` to
`data-theme="name"`, existing customizations that depend on should be
updated.

1. The `og:description` should be "a one to two sentence description of
your object"
* It shouldn't output all the user inputted content -- it would be
pretty huge.
* Maybe it only needs at most 300 bytes.
2. Do not render commit message as HTML
Add more useful Open Graph metadata for commit and file URLs:
- Set `og:title` to the page title, which is a concise summary in both
cases (`<commit message> · <commit hash>` and `<filename> at <branch>`,
respectively)
- Set `og:description` to the commit message body, if available
- Set `og:url` to the relevant URLs instead of the repo URL
Also move the relevant meta tags into a separate template as they now
take up the majority of the base head template.
Now that we have the `/assets` directory, we can put`licenses.txt`
directly into it instead of incorrect `/js` path which was previously
only done to avoid reserving a username.

Before:
* `{{.locale.Tr ...}}`
* `{{$.locale.Tr ...}}`
* `{{$.root.locale.Tr ...}}`
* `{{template "sub" .}}`
* `{{template "sub" (dict "locale" $.locale)}}`
* `{{template "sub" (dict "root" $)}}`
* .....
With context function: only need to `{{ctx.Locale.Tr ...}}`
The "ctx" could be considered as a super-global variable for all
templates including sub-templates.
To avoid potential risks (any bug in the template context function
package), this PR only starts using "ctx" in "head.tmpl" and
"footer.tmpl" and it has a "DataRaceCheck". If there is anything wrong,
the code can be fixed or reverted easily.
So I found this [linter](https://github.com/Riverside-Healthcare/djlint)
which features a mode for go templates, so I gave it a try and it did
find a number of valid issue, like unbalanced tags etc. It also has a
number of bugs, I had to disable/workaround many issues.
Given that this linter is written in python, this does add a dependency
on `python` >= 3.8 and `poetry` to the development environment to be
able to run this linter locally.
- `e.g.` prefixes on placeholders are removed because the linter had a
false-positive on `placeholder="e.g. cn=Search"` for the `attr=value`
syntax and it's not ideal anyways to write `e.g.` into a placeholder
because a placeholder is meant to hold a sample value.
- In `templates/repo/settings/options.tmpl` I simplified the logic to
not conditionally create opening tags without closing tags because this
stuff confuses the linter (and possibly the reader as well).
Clarify the "link-action" behavior:
> // A "link-action" can post AJAX request to its "data-url"
> // Then the browser is redirect to: the "redirect" in response, or
"data-redirect" attribute, or current URL by reloading.
And enhance the "link-action" to support showing a modal dialog for
confirm. A similar general approach could also help PRs like
https://github.com/go-gitea/gitea/pull/22344#discussion_r1062883436
> // If the "link-action" has "data-modal-confirm(-html)" attribute, a
confirm modal dialog will be shown before taking action.
And a lot of duplicate code can be removed now. A good framework design
can help to avoid code copying&pasting.

It's been disabled by default since 1.17
(https://github.com/go-gitea/gitea/pull/18914), and it never really
delivered any benefit except being another cache layer that has its own
unsolved invalidation issues. HTTP cache works, we don't need two cache
layers at the browser for assets.
## ⚠️ BREAKING
You can remove the config `[ui].USE_SERVICE_WORKER` from your `app.ini`
now.
As discussed in
https://github.com/go-gitea/gitea/pull/24953#issuecomment-1565630156.
## ⚠️ BREAKING ⚠️
1. The `ui.THEME_COLOR_META_TAG` setting has been removed. If you still
need to set the `theme-color` meta tag, add it via
`$GITEA_CUSTOM/templates/custom/header.tmpl` instead.
2. The non-standard `default-theme` meta-tag added in
https://github.com/go-gitea/gitea/pull/13809 has been removed. Third
party code that needs to obtain the currently loaded theme should use
the `theme-<name>` class on the `<html>` node instead, which reflect the
currently active theme.
The 500 page was not loading theme CSS, so always appeared in light
theme. This extracts the stylesheets into a shared template used by all
pages.

Small related rant: I think there should only be one `<head>` in all of
the templates, but I see it was deliberatly done that the 500 page has
its own `<head>` because "it should only depend the minimal template
functions", but I disagree because we are missing a lot of things that
are in the regular `<head>`.
When `<!DOCTYPE html>` is present, the default (and only valid) charset
it `utf-8` so it does not need to be specified.
Also we do serve with HTML with `Content-Type: text/html;
charset=utf-8`, so it is duplicate info anyways.
Partially for #24457
Major changes:
1. The old `signedUserNameStringPointerKey` is quite hacky, use
`ctx.Data[SignedUser]` instead
2. Move duplicate code from `Contexter` to `CommonTemplateContextData`
3. Remove incorrect copying&pasting code `ctx.Data["Err_Password"] =
true` in API handlers
4. Use one unique `RenderPanicErrorPage` for panic error page rendering
5. Move `stripSlashesMiddleware` to be the first middleware
6. Install global panic recovery handler, it works for both `install`
and `web`
7. Make `500.tmpl` only depend minimal template functions/variables,
avoid triggering new panics
