Additional error info (text of the exception thrown by low level C++
code) is shown inside a text box of the same style as used for the
advice on the 404 error page (we either need to change the name of the
CSS style, or introduce a separate style for this piece of information).
The external link blocker page isn't actually translated since it is not
managed by the viewer. Will port the translation code from the viewer.js
in next commit.
The failing test point in the ServerTest.Http404HtmlError unit-test
has been superseded by the enhanced ServerTest.HttpSexy404HtmlError
unit-test, resulting in a clean test-suite.
Translation of the multi-line/multi-paragraph advice is done under the
assumption that its structure (5 paragraphs, two of which serve as
entries in a bulleted list) can be preserved in the translations by
proper phrasing, i.e. the advice must be translated as a whole rather
than each of its sentences (which act as units of translation) separately.
- Enabled translation on the new 404 error page
- Translated its title & heading
This commit also fixes the failure of the ServerTest.UserLanguageControl
unit-test.
The only remaining failing test case is ServerTest.Http404HtmlError
(only for url=/ROOT%23%3F/content/zimfile/invalid-article?userlang=test).
Converted a few failing test points of the ServerTest.Http404HtmlError
unit-test into a new unit-test ServerTest.HttpSexy404HtmlError.
Some broken test cases still remain.
The page doesn't support translation, yet.
The new 404 error page is used only when accessing ZIM file content
(i.e. as a response from the `/content` API endpoint).
One notable difference from the previous error page is that now no hint
is provided about whether the error is due to trying to access a
non-existent book/ZIM-file or non-existent resource inside a valid
book/ZIM-file (previously such a hint was present in the suggested
search URL). However, when displayed in the viewer this difference can
be seen in the viewer toolbar - book related buttons are hidden if the
URL points to a non-existent book.
This change breaks some unit tests. They will be fixed in a separate
commit.
- Implemented a spinner to improve user experience while ZIM content is loading in the viewer iframe.
- Added .loader and .spinner styles in kiwix.css.
- The iframe content is initially hidden (visibility: hidden) and will be displayed once loading completes.
- Used CSS animations (@keyframes spin) for a smooth rotating effect.
- Refactored language code handling to replace multiple comma-separated values with 'mul'.
- Single-language entries remain unchanged.
- created the helper function to get the lang tag
- ensured the consistent behaviour for js and nojs version for the kiwix library view
Chrome on Android doesn't support displaying PDF documents inline so an
attempt to load a PDF into the Kiwix viewer iframe fails in a way that
may be confusing to the users. In such situations it is better to offer
to the users to download the PDF file so that they can view it with a
dedicated application. Making the clicked PDF link to open in a new
tab/window achieves exactly that effect.
External links with target="_blank" attribute are opened in a new tab/window.
Also included metaKey (Command key under Mac) in the list of click
modifiers that make the link to be opened in a new tab.
Note however that no upper limit is set on the width of the
autocompleter box - it is possible, but I don't see how we could
come up with a good value for it.
Added to test book descriptions words that serve as keywords
for query syntax with boolean operators (or, and, not, xor, near, adj) enabled.
Note that the change in indexed text has lead to the change in the order
of returned results.
Added a test that checks that the static resources returned by the
server have content that matches their cacheid. This test currently
fails because some binary resources (e.g. png images) are garbled by the
dos2unix conversion.
- Changed the position of download button to the end of tile and
added a proper download icon to it. When the button is hovered it
becomes darker.
- Also internationalized the "Download" text on the modal download widget
and added download size information to it.
Zimit2 ZIMs employ Wombat for client-side rewriting of URLs. The latter
interferes with our approach of handling in the viewer CTRL/SHIFT-clicks
on links inside articles. This commit disables Wombat temporarily while
changing the href attribute of the clicked link.
Links that should be handled/opened by external applications - such as email
addresses (mailto:), phone numbers (tel:), etc - are opened by the
viewer in a new tab/window, thus avoiding any issues with content
security policy.
Switched display of ZIM sizes from decimal (MB) to binary (MiB) units.
Also made the size value to be formatted in a more human friendly way
(fractional part is shown only to provide at least three significant
digits).
