The version of LuaTeX that ships with TeX Live 2016 now gives the
following message after processing a document that yields no pages
of output:
"warning (pdf backend): no pages of output."
The lowercase "n" in "no" is a change that caused our parser not to
pick up the message.
A few parts of our code depend on correctly identifying the output
format of LaTeX commands. One specific bug is that because the
output file was not correctly set, it was not removed after an
error. For example, this commit fixes the following bug:
1. Create a new document that contains "hello\blah" where \blah is
in an ERT box.
2. Compile with PDF (LuaTeX). You'll get an error because of \blah.
3. Close the error dialog.
4. Remove the text "hello" and compile again with PDF (LuaTeX).
The error dialog is shown and the "Show Output Anyway" button is
enabled. If you click it, it shows the previously compiled PDF (with
the text "hello"). With this commit, the button is correctly
disabled (and the output file is deleted).
LyX did not distinguish compressed and uncompressed svg files previously.
Therefore XHTML export of vector graphics did use svgz images directly, which
is not supported by browsers. If svg and svgz are treated as two formats then
all works fine. This is also consistent with the loadable image formats
reported by qt: It reports both svg and svgz.
The gunzip dependency in converters is not new (it is already used internally),
but the gzip dependency is new, so it might not be available on windows.
This is not important at the moment, since we do not yet need to convert svg
to svgz, I only added the converter for completeness.
Some qt versions report both "jpeg" and "jpg" as loadable file extensions.
In this case the jpg format was added twice previously. This does not happen
anymore with the new code, and it works as well if only "jpg" or only "jpeg"
is reported.
As discussed on the list some time ago. cmake produces .po files already in
native line endings. Only autotools on mingw might produce wrong line endings
now, but I am pretty sure that nobody updates .po files using autotools on mingw.
It is wrong to assume that direction is left-to-right when no indication exist.
Add a new enum with values LtR, RtL and Auto to be used as argument of
the private text() methods. When direction is Auto, let Qt decide how
the string shall be layed out.
Fixes bug #10169.
TocModels::reset() in GuiView::structureChanged() collapses the TocWidget, and
therefore requires an update right after, which was missing.
In fact, profiling TocWidget::updateView() shows that delaying the update is
good only for fast keypresses (essentially movement). It costs 5% of a
char-forward operation in a document with approx. 100 table of contents
items. The update optimisation has been rewritten to take this data into
account.
The new functions parBottomSpaging and parTopSapcing return below/above each paragraph.
This allows to remove the TopBottomSpace argument and makes the code a
bit clearer.
Now that Row has a pit() member, it is possible to use it instead of passing an extra pit_type parameter to a function which already has access to a Row.
Change the various paint* helpers to take a single row element as argument.
Do not update x_ in the various paint* helpers. Constify them. Update x_ in paintText and paintOnlyInsets instead.
Remove an empty call to paintForeignMark in paintInset (the call did nothing since orig_x == x_ at this point).
It is actually easier to set the 20 pixels margin in redoParagraph, since it is not necessary to take newlines in account when deciding what is the real last row of the paragraph.
Moreover this solves the following bug (present in 2.1.x too): when the document ends with a newling, the bottom margin disappears.
Update PAINTING_ANALYSIS with new tasks.
* remove optional arguments to the helpers that use a FontInfo
* add a textwidth argument to the text() methods that are used by rowpainter.
Now textwidth is only computed if a null value was passed to the
text() method. This means that in the use case of rowpainter, no
textwidth needs to be computed.
The initial values for maxasc and maxdes (renamed from maxdesc) is obtained as a maximum of max ascents/descents of all row elements.
This allows to get rid of Paragraph::highestFontInRange and FontList::highestInRange.
Some auxilliary variables declarations are also moved to where they are needed.
Let breakRow return a boolean indicating whether an additional row is
required (after a newline) and use that to replace the code that added
an extra row when a paragraph ends with a newline.
There are two main cases:
* when drawing is disabled from the start, use a simplified code that only paints insets (in order to cache positions).
* when the row is not visible, do the same.
The goal of this optimization is to be able to always run a no-drawing draw after the metrics have been computed.
