Correctly handle formatting of tables containing thead and/or tfoot, but
without any tbody, to prevent including thead/tfoot content twice within
the table's derived body.
* lisp/net/shr.el (shr--fix-tbody): Omit 'thead' and 'tfoot' from
implicit body. (Bug#71685)
* test/lisp/net/shr-resources/table.html:
* test/lisp/net/shr-resources/table.txt: New tests for table rendering.
Previously, for images with no alt-text, the zoomed image wouldn't get
properly inserted. For images with alt-text, both the zoomed and
unzoomed image would be displayed at once (bug#71666).
* lisp/net/shr.el (shr-sliced-image): New face.
(shr-zoom-image): Reimplement using
'next/previous-single-property-change', and don't bother deleting any of
the text.
(shr-image-fetched): Clean up any overlays when deleting the old region.
(shr-put-image): Ensure we always have a non-empty string to put the
image on. For sliced images, just use "*", since we'll repeat it, so we
can't preserve the original buffer text exactly anyway. Apply an
overlay to sliced images to prevent unsightly text decorations.
(shr-tag-img): Move the placeholder space insertion where it should be
and explain what it's doing.
* test/lisp/net/shr-tests.el (shr-test--max-wait-time)
(shr-test-wait-for): New helper functions.
(shr-test/zoom-image): New test.
The 'shr-fill-...' functions handle both hard-filling (adding
newlines to break long lines) and indentation. Setting
'shr-fill-text' to nil currently causes these functions to be
short-circuited completely, so e.g. blockquotes are no longer
indented, whereas the intent of this user option is only to
prevent hard-filling to let visual-line-mode reflow text.
* lisp/net/shr.el (shr-fill-lines): Document that the function
handles more than just filling; move the 'shr-fill-text' check...
(shr-fill-line): ... here, after indentation has been taken care
of.
* test/lisp/net/shr-resources/blockquote.html:
* test/lisp/net/shr-resources/blockquote.txt: New test resources.
* test/lisp/net/shr-tests.el (shr-test--rendering-check): Rename
from 'shr-test', to make the relationship with the 'rendering'
testcase clearer; prefer 'file-name-concat' to 'format'; raise
ERT failure if need be, calling (ert-fail ...) directly instead
of (should (not (list ...))).
(shr-test--rendering-extra-configs): New variable to easily check
that user customizations do not degrade rendering.
(rendering): Consult that new variable; delegate failure-raising
to reduce duplication.
* lisp/net/shr.el (shr-correct-attribute-case): New constant.
(shr-correct-dom-case): New function to correct SVG attribute case.
(shr-tag-svg): Correct SVG attribute cases before using them.
* lisp/net/shr.el
(shr-heading): Propertize heading with level.
(shr-outline-search): An 'outline-search-function' that finds
headings using text property search.
(shr-outline-level): Outline level for 'shr-outline-search'.
(Bug#66676)
* lisp/net/shr.el
(shr-max-inline-image-size): New custom variable.
(shr--inline-image-p): New helper function to decide if an
image should be inserted inline.
(shr-insert, shr-put-image, shr-tag-img): Use
'shr-max-inline-image-size' to insert some images inline.
(Bug#66676)
* lisp/net/shr.el (shr-fill-text, shr-sup-raise-factor)
(shr-sub-raise-factor, shr-image-ascent): New custom variables.
(shr-fill-lines): Only fill if 'shr-fill-text' is non-nil.
(shr-put-image): Use 'shr-image-ascent' as value of :ascent.
(shr-rescale-image, shr-make-placeholder-image): Use
'shr-image-ascent'.
(shr-tag-sup, shr-tag-sub): Use 'shr-sup/sub-raise-factor'.
(Bug#66676)
* lisp/net/shr.el (shr-count): Prefer handwritten code to using
'seq-count', as it's more performant.
Problem reported by Mattias Engdegård <mattiase@acm.org>.
* lisp/net/shr.el (shr-count):
* lisp/progmodes/idlwave.el (idlwave-count-memq): Use seq-count.
(idlwave-count-eq): Use seq-count. Make obsolete, as it is unused.
* lisp/net/eww.el (eww-tag-input): Don't claim to have an URL here
(bug#58091).
* lisp/net/shr.el (shr-next-link, shr-previous-link): Search for
shr-tab-stop instead of shr-url so that we can be more general.
(shr-urlify): Mark all links as tabbable-to.
* lisp/net/eww.el (eww-render): Enable undo after rendering. This
allows using `undo' in text input boxes.
(eww-setup-buffer): Disable undo before rendering (bug#57750).
* lisp/net/shr.el (shr-image-fetched): Inhibit undo tracking.
* lisp/net/eww.el (eww-update-header-line-format): Use
string-pixel-width (since we don't care about shr-use-fonts here).
* lisp/net/shr.el (shr-string-pixel-width): Use
`string-pixel-width', which should be faster.
* src/window.c (struct saved_window): New member 'vscroll'.
(Fset_window_configuration, save_window_save): Save and restore
the window's vscroll value.
* lisp/net/shr.el (shr-insert-document): Restore the original
window's hscroll, in case we are rendering in a window other than
where the document will be eventually displayed. This avoids
resetting hscroll of windows we use temporarily for shr's
rendering job. (Bug#56008)
* lisp/net/shr.el (shr-save-contents, shr-get-image-data): Don't call.
(shr-encode-url): Make obsolete. (This function makes no sense.)
(shr-tag-img): Don't call.
* lisp/net/eww.el (eww-open-file): Use it.
(eww-browse-url): Ditto.
* lisp/net/shr.el (shr-expand-url): Allow loading relative Tramp
files if we're reading from a file:// document.
* lisp/url/url-file.el (url-allow-non-local-files): New user option
(bug#40425).
* lisp/net/shr.el (shr-descend): Use a marker (because we may be
altering the text later for indentation), and mark the start, not
the end of the tag (bug#53409).
(shr-tag-a): Ditto.
* lisp/international/textsec-check.el (textsec-propertize): New
function.
(textsec-check): Only check, don't alter STRING.
* lisp/international/textsec.el (textsec-url-suspicious-p): New
function.
* lisp/net/shr.el (shr-tag-a): Mark suspicious links.
