Now the search results page is presented by the backend in the language
controlled by the value of the `userlang` URL query parameter (or, if
the latter is missing, the value of the `Accept-Language:` HTTP header).
Note that the front-end doesn't yet take advantage of this
functionality.
Note that static/skin/languages.js must be generated/updated manually
by running the static/generate_i18n_resources_list.py script. Previously
it had to be done only when new languages were added. Now the
translation counts will also need to be updated when new entries are
added to static/skin/i18n/en.json or upon merging a few translatewiki PRs.
... so that extra info about the count of translated strings can be
added.
Note that due to increased size skin/languages.js lost its
too-small-to-be-worth-compressing status.
Added a test case demonstrating how a bad error response could be
generated if </script> appears inside KIWIX_RESPONSE_DATA. That seems to
be the only problematic interaction between HTML-like syntax inside
javascript code (hence the deleted XXX comments on the other two test
cases).
But the question is do we need all of them to be translatable in the
frontend? Maybe only responses to /random, /content and /search endpoints (that
are displayed in the viewer) should be translatable?
Also, the test cases against vulnerabilities in kiwix-serve seem to suggest
that KIWIX_RESPONSE_DATA should be HTML-encoded too.
This commit demonstrates front-end-side translation of an error page
for a URL like /viewer#INVALIDBOOK/whatever (where INVALIDBOOK should
be a book name NOT present in the library).
Known issues:
- This change breaks a couple of subtests in the
ServerTest.Http404HtmlError unit test.
- Changing the UI language while an error page is displayed in the
viewer doesn't retranslate it.
Non-HTML-encoded HTML-template data causes problems in HTML
even when it appears inside JS string (resulting in the <script> tag being
closed by a </script> appearing inside a JS string).
Besides, the KIWIX_RESPONSE_DATA and KIWIX_RESPONSE_TEMPLATE variables
are set on the window object so that they can be accessed from the top
context.
This commit eliminates the need for the `escapeQuote` parameter in
`escapeForJSON()` (that was introduced earlier in this PR) since now it
is set to false in all call contexts. However from the consistency point
of view, the default and intuitive behaviour of `escapeForJSON()` should
be to escape the quote symbols, which justifies the existence of that
parameter.
This is a shortcut change since it doesn't make sense to send the error
page template with every error response (the viewer can fetch it from
the server once but that's slightly more work).
- More familiar escape sequences for tab, newline and carriage return
symbols.
- Quote symbol is escaped by default too, however that behaviour can
be disabled for uses in HTML-related contexts where quotes should then
be replaced with the character entity "
Next to come warc2zim archive will come with "wombat" embedded.
The purpose of wombat is to be an interface with js code to mask that
we are in a scrapped/zim context to the js.
So it rewrite the `.href` attributes to the original url (ie, an
absolute url to the original website), even if the local relative url
is valid.
Let's ask to wombat to not rewrite href in our special case.
Attempts to use the same color for buttons yielded poor results: viewer
toolbar buttons don't look nice on the dark background used for the
filter controls on the library page, whereas the light background of the
viewer toolbar buttons doesn't play well with the filters on the library
page which seem to be designed around the contrast effect.
There was a slight difference (between index.css and taskbar.css) in the
margin values of the UI language selector button, however the values
taken from taskbar.css don't seem to have any visible impact on the
welcome/library page (controlled by index.css).
Moved from index.css into kiwix.css some CSS with global effect thus
making it apply to the viewer too.
Extra font-size directives in taskbar.css are needed to undo the effect
of 'font-size: 62.5%' now applied to the 'html' element type.
The new file kiwix.css is intended to host the intersection of index.css
and taskbar.css. In this commit only font definitions have been moved
into it.
