This can happen when the inset that contains the cursor is outside of
the screen.
THis is only a workaround. The real solution would be a
processUpdateFlags(FitCursor) call, but the code is not ready for that
yet.
Fixes bug #11296.

The part of code that removed space at start of paragraph have been
there forever, but its intent is unclear. For example, cutting text at
the end of a paragraph will lead to remove space at the start of this
same paragraph.
The removal of this functionality is offset by a rewrite of DEPM that
makes it more thorough.
Fixes bug #10503.

The goal of this patch is to make "self-insert <string>" act as a
sequence of individual self-insert calls. Once it is done, the
insertion of the commit string in GuiWorkArea can use that, which
fixes the issues described in bug 11183.
1/ in InsetMathNest, SELF_INSERT is rewritten to be a proper loop of
interpretChar, instead of inserting the string as characters. This
solves the issue of interpreting ^ properly.
2/ the text version does not need to be changed (the loop is rewritten
using a range, though).
3/ Then {{{GuiWorkArea::inputMethodEvent}}} is changed to invoke
directly self-insert. This removes the update issues.
Fixes bug 11183.

The code in 90cfe4ec3 only handled the cells which metrics are
computed directly, and missed those who were linearized inside a MathRow.
To fix this, we use the fact that all the positions in a math row have
the same height and make MathRow::metrics return a boolean indicating
whether it contains a caret for a given bufferview.
Fixes bug #11153.
(cherry picked from commit a3868e40a4)
Compute a height from current font and current cell vertical
dimensions in MathData::metrics(), because this is where current font
is known.
Introduce BufferView::setCaretAscentDescent to remember this value.
This mechanism is not used for text because Cursor::current_font is
restored by undo, and the caret height would not be changed then. But
in principle it is doable.
(cherry picked from commit 90cfe4ec3b)
When computing a cell metrics, it is now possible to specify whether it
is tight (at least as tall as 'x') or not (as tall as the max height of
the font).
Use this to make sure that grid insets have large enough cells. It
will probably appear that other cells needn't be tight. Currently, the
only cell which is known to be tight is the nucleus of the root inset.
Others should be examined one by one. It might be that the default of
MathData::metrics tight parameter should be `false'.
Fixes bug #11050.
(cherry picked from commit 7bcb78a778)
The value used here is the x height. It would be nice to see what the
TeXbook really says.
This makes a big difference with \tilde{.}, for example.

Add a `cancel' boolean to macroModeClose() that just removes all trace
of what has been entered instead of finalizing it.
When entering a macro in mathed, let LFUN_ESCAPE invoke
macroModeClose(true). The new semantics of LFUN_ESCAPE in mathed is
thus to abort the input of a macro name.
Fixes bug #9251.

Normally the two stages of drawing are
1/ compute metrics of insets/rows/paragraphs/mathrow...
2/ draw the elements and cache their positions
Now the three stages are
1/ metrics
2/ nodraw: do not draw the elements, but cache their position
3/ draw the elements (and store again their position; it does not
seems to hurt performance).
Revive the NullPainter: this replaces the setDrawingEnabled mechanism
with a painter that does nothing. The advantage is that updatePosCache
(renamed from setPosCache) does not need anymore to be invoked from
the frontend.
updatePosCache (the nodraw stage) is called at the end of
BufferView::updateMetrics.
This is a follow-up to 758de957.
- unify the metrics and drawing of \sqrt and \root using helper
functions mathed_root_metrics and mathed_draw_root.
- compute the vertical spacing above the nucleus of the root following
rule 11 of the TeXbook. In particular, it is different in inline and
display style.
- draw the root glyph without hard-coded pixel values. Make the line
width depend on the zoom.
more work is needed to implement properly rule 11:
- Ideally, we should use sqrt glyphs from the math fonts. Note that
then we would get rule thickness from there.
- The positioning of the root MathData is arbitrary. It should
follow the definition of \root...\of... in The Texbook in
Apprendix B page 360.
Fixes bug #10814.

When pasting "\big" without any following delimiter, avoid
processing the same token again and again. For unknown reasons,
the delim docstring turns out to always be not empty: even when
it simply contains a '0' (no delimiter follows), its length is 1.
Fixes bug #11027.
(cherry picked from commit 8e8b3f6104)
By default, inactive math corners are invisible. In practice they are
annoying because they are visible when selecting text, and they can
also overwrite some parts of the equation.
The code in Inset::drawMarkers2, which is only used for maths, is
moved to InsetMathHull. Moreover, the inactive corners are not drawn
when they have the same color as the math background. A better way to
achieve this would be to set the color to transparent, but we do not
support this yet.
(cherry picked from commit 68614e9783)
This spacing was wrongly removed at 361bd53b as part of the
introduction of proper spacing between elements, but it only introduces
some breathing space around the delimiters. This will not be necessary
anymore when/if we use proper delimiters from the cmex10 font.
(cherry picked from commit 4cb5cc0c7d)
- If a display math not starting a new paragraph is deleted, the
current \lyxdeleted macro (if any) must be closed and a new one
started, otherwise the display math will be shifted up.
- Use \linewidth instead of \columnwidth because the former will adapt
to the reduced horizontal width in list environments, avoiding shifting
to the right the diplay math.

After 6642152e, user macros were no longer wrapped in \ensuremath. In 2.2 and
before, InsetMathMacro behaved as follow:
* Textmode global symbols are wrapped in \text when in math.
* Other global symbols, and user macros, are wrapped in \ensuremath when in
text.
* Undefined macros (ERT) are wrapped neither in \text nor in \ensuremath.
This is also consistent with the documentation of MathEnsurer in
mathed/MathStream.h.
This patch defines InsetMathMacro::currentMode() accordingly (respectively
TEXT_MODE, MATH_MODE and UNDECIDED_MODE) and uses it to determine the output.
After this patch, there is a mismatch between screen and pdf output for user
macros in \text. This is not a regression wrt 2.2 and is because linearization
does not satisfy currentMode() currently.

Traditionally LyX behaves differently when the directive DEVEL_VERSION
is defined at compile time. This covers
* more detailed description of current position in status bar
* the help files are open in read/write mode
* more detailed debug output in the View Source panel
This patch introduces the new function devel-mode-toggle that allows
to use devel mode in stable releases, and vice versa.
The information is saved in the session file. The default is to
disable devel mode.
Remove all traces of DEVEL_VERSION in autoconf and cmake
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.
The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.
Further details on the steps below, in case they're of interest to
someone else in the future.
1. Checkout a fresh and up to date version of src/
git pull && git checkout -- src && git status src
2. Ensure there's a suitable .clang-format in place, i.e. with options
to fix the comment at the end of namespaces, including:
FixNamespaceComments: true
SpacesBeforeTrailingComments: 1
and that clang-format is >= 5.0.0, by doing e.g.:
clang-format -dump-config | grep Comments:
clang-format --version
3. Apply clang-format to the source:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
4. Create and filter out hunks related to fixing the namespace
git diff -U0 src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace.patch
5. Filter out hunks corresponding to simple fixes into to a separate patch:
pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n' \
-e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n' \
fix_namespace.patch > fix_namespace_simple.patch
6. Manually review the simple patch and then apply it, after first
restoring the source.
git checkout -- src
patch -p1 < fix_namespace_simple.path
7. Manually review the (simple) changes and then stage the changes
git diff src
git add src
8. Again apply clang-format and filter out hunks related to any
remaining fixes to the namespace, this time filter with more
context. There will be fewer hunks as all the simple cases have
already been handled:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
git diff src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace2.patch
9. Manually review/edit the resulting patch file to remove hunks for files
which need to be dealt with manually, noting the file names and
line numbers. Then restore files to as before applying clang-format
and apply the patch:
git checkout src
patch -p1 < fix_namespace2.patch
10. Manually fix the files noted in the previous step. Stage files,
review changes and commit.
The RenderButton object now has a inherit_font_ property. It is set
depending on the value of Inset::inheritFont().
This is a better fix than 55533804, which caused bugs #10682 and #10677.
Fixes bug #10258
With these changes, equation numbers are shown properly on screen.
When setting is default, we guess the side using these two rules
* ams(art|book) and siamltex classes are leqno by default. This is
signalled because the classes provide "leqno" (in amsdefs.inc). If
there are other classes that do this in output, the relevant classes
should be updated.
* the language arabic_arabi also sets leqno by default. This is
currently hardcoded for lack of a better idea.
Besides, a few bugs are fixed:
* use mathrm instead of mathbf for numbers metrics
* set spacing between maths and labels in inches
This is done by two things:
1/ the equation returns LefAlign as display() value
2/ Inset::indent() return a value (in general 0) that should be added
on the left (or right in rtl) of the inset when it is flushed.
The code that uses these values is in TextMetrics::computeRowMetrics.
