Qt only supports SVG 1.2 tiny, so we prefer to convert on our own if an
explicit converter is defined and the converter cache is used (otherwise
the conversion would be too expensive).
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).
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.
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.
This is a first cleanup step. More complex rules have to be
implemented on top of this.
Use proper spacing \thinmuskip, \medmuskip and \thickmuskip instead of
ad-hoc values.
Rename isRelOp to isMathRel and introduce isMathBin and isMathPunct
(for InsetMathChar and InsetMathSymbol). Update the categories of
characters in InsetMathChar according to LaTeX source (fontmath.ltx).
Set correctly the spacing around mathrel, mathbin and mathpunct
elements. Use \thinmuskip around MathDelim instead of a hardcoded 4.
This is related to bug #8883.
There is already a spacing of 2 pixels on each side of a button (e.g. collapsed inset). There is no need to add one extra pixel for command insets.
Fixes part of bug #10149.
The computation of the width of the button was wrong. If <--> stands for TEXT_TO_INSET_OFFSET/2 spacing, and if `[]' marks the button's limits, then the intent is
<-->[<-->button text<-->]<-->
Therefore the physical grey rectangle width is
width - Inset::TEXT_TO_INSET_OFFSET
With this change, the spacing on the right of the button is not larger than the left one.
Fixes bug #10147.
The way it works is:
* the inset defines allowParagraphCustomization() correctly
* Text::getStatus acts on it.
Note that, in Text::getStatus, testing for cur.inset().allowParagraphCustomization() does not make much sense, since one should pass the cursor idx as parameter. Actually, for some reason the safest bet is to use the owner of the Text object as inset.
The way it works is:
* the inset defines forcePlainLayout() correctly
* Text::getStatus acts on it.
Note that, in Text::getStatus, testing for cur.inset().forcePlainLayout() does not make much sense, since one should pass the cursor idx as parameter.
There are many other lfuns that do not have to be handled directly by insets. InsetScript in particular has tests for way too many lfuns.
This method did access more CursorSlice than Text. It is only a setter for
CursorSlice with some bound checking. The new signature is
setPitPos(pit_type, pos_type).
The old name would be confusing wrt setSelection(), which does additional checks.
This one is a pure acessor, and the more complete methods are
* setSelection(), which avoids empty selections
* clearSelection(), which resets anchor, and sets word selection and mark more to false.
Most of the code should use these two instead of selection(bool), but this is for later.
