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.
The original use case for this bug is entering an overset inset when
there is a selection. The expected result was to have the selection
pasted in main text, but the result was to have it in the cell.
Insets already have idxFirst() that is able to set cursor to the
"entry" cell of an inset. This patch introduces firstIdx(), which is
the index of this cell and uses it in idxFirst() (idem for
lastIdx/idxLast).
As a consequence, several instances of idxFirst/idxLast can be removed.
Now for the real fix: the two places where the cell in which selection
is inserted seem to be:
* Cursor::macroModeClose
* Cursor::handleNest
These two methods are changed to insert material in the entry cell
instead of cell 0.
idxFirst/Last methods are added to InsetMathRoot and InsetMathStackrel
so that the natural entry point is the nucleus of those insets.
Finallly, a typo is fixed in InsetMathNest::edit() where enter_front
computation was incorrect.
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.
Use proper value for above/below skip (12pt) instead of the hardcoded
12 pixels.
Add forgotten skip before display math preview.
Make "too small preview" size dpi-dependent.
Make gap in front of equation (what is it good for, BTW?) dpi-dependent.
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.
The function does not use for now any information from the BufferView
(only lyxrc), but this should eventually change if we want to honor
multi monitor setups properly.
A basic class like Length should not depend on something from
frontend.
This change allows to remove several dummy implementations of
theFontMetrics().
This spacing was wrongly removed at 361bd53b as part of the
introduction of proper spacing btween 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.
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.
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.
Basically, everything that does not depend on a BufferView should move
there. Some methods that do not seem to need a BufferView, like
selHandle or IdxFirst or push actually depend on it and could not be
moved.
This allows to simplify a few uses of recordUndo helpers.
- Move some methods to DocIterator: nextMath, prevMath, getPossibleLabel,
getEncoding;
- Move some methods to CursorData: setCursor, setCursorSelectionTo,
(setCursorTo|normal|reset)Anchor, (set|clear)Selection,
sel(|ection)(Begin|End), selectionAsString, info, currentState,
(mark|clear|check)NewWordPosition, fixIfBroken, sanitize, all undo
related methods, reset, isInside, leaveInset, current mode;
- kill some unused methods: macromode, replaceWord, setScreenPos, touch,
markInsert, markErase;
- Move code around to group things, and add a few comments (a lot remains to be done).
This changes lead to some related changes in other classes: removal,
change of parameter.
No intended change.
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.
- 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.
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.
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.
This is preliminary work to make roots look more like in TeX output:
* correct font size for root order
* set minimum size of the root from the max ascent descent of the
font. This is what TeX does.
* fix drawing, and in particular horizontal size.
More needs to be done, in particular:
* handle zooming and dpi correctly by removing hardcoded pixel values.
* factor the code for the two types of roots in one.
The RenderButton object now has this property. It is set depending on
the value of inheritFont() method that is currently only set for
InsetRef, InsetBibtex and InsetCitation.
Fixes bug #10258
The special mode used by macros where the macro name is displayed as
grey text in a box is now one of the possible marker types for any
inset. The new code puts the macro name below the text, which means
that only the text below the current line will be moved. This makes
edition much more comfortable. The grey border around the contents has
been removed too.
The marker_type enum has been moved from Inset to InsetMath. A
markerMargin() function returns the horizontal margin required on each
side for the marker. Only the corner-type markers MARKER and MARKER2
need some.
A new BOX_MARKER enum value has been added and is taken care of in
afterMetricsMarkers (renamed from metricsMarkerVertical) and
drawMarkers.
The InsetMath::marker() macro now takes a BufferView pointer as
argument, so that the marker type can depend on editing state.
MathRow::metrics now makes changes to the MathRow object when needed.
The specific metrics/draw code in MathMacro has been removed and
replaced by assertions. Code in addToMathRow and marker is adapted to
reflect the cases where linearization is possible.
It is not clear that the optimization is a gain, but it is clear that
it has a cost: some elements of formulas will not be present in the
position cache.
Fixes bug #10520.
Coverity complains that we might read strings that are arbitrary
large, and that this can be a security issue. This is a problem in
particular, when we feed these strings to from_utf8(), which coverity
flags as dangerous for some reason.
The best solution would be IMO to model from_utf8() properly, but I do
not know how to do that. Here I try a different solution, where I
cannot read a string larger than 64k from the file.
Let's see whether this removes part of coverity warnings.
Now the selection is not done by the inset, but by the MathData
itself. This allows for some code simplification and avoids an
extra redraw.
Additionally, this fixes the selection inside macros, which was broken
by the new MathRow code.
Now backspace and delete in text will select non-empty math and text insets
before deleting them. This is consistent with what happens in math already.
This is implemented for InsetText as well but can be disabled in case of
negative feedback.
This can be set for any sort of inset with the new virtual method
Inset::confirmDeletion.
New option "force" for the LFUN_*_DELETE_* commands, that bypasses the
confirmDeletion check.
The special mode used by macros where the macro name is displayed as
grey text in a box is now one of the possible marker types for any
inset. The new code puts the macro name below the text, which means
that only the text below the current line will be moved. This makes
edition much more comfortable.
The marker_type enum has been moved from Inset to InsetMath.
A new BOX_MARKER enum value has been added and is taken care of in
afterMetricsMarkers (renamed from metricsMarkerVertical) and
drawMarkers.
The InsetMath::marker() macro now takes a BufferView pointer as
argument, so that the marker type can depend on editing state.
MathRow::metrics now makes changes to the MathRow object when needed.
The specific metrics/draw code in MathMacro has been removed and
replaced by assertions. Code in addToMathRow and marker is adapted to
reflect the cases where linearization is possible.
From now on \kern and \mkern remain as ERT as long as the length is invalid.
Fixes#10539 (regression at 10c8d51b).
The only way to produce an InsetMathKern now is via parsing (i.e. file opening
or copy-paste). This is because there has never been any sensible way to input a
valid InsetMathKern, but this is another issue.
Since in InsetMathNest::cursorPos we do not know what is the value of
the row element before value of a given BOX, it does not make sense to
set the cursor at a given offset from the start of the MathData
object.
Therefore here we set the cursor in the middle of the MathData object,
which unfortunately may or may not be visually centered wrt the BOX.
The best solution would be to use the MathRow data here, but
unfortunately this is not completely trivial.
This patch replaces 7917ebcc4.
Horizontal space is now added for linearized macros too.
Vertical space handling is done in a separate method.
This is in preparation for handling of 'box' macro editing mode in
MathRow.
InsetMathDelim does not need markers because the delimiters are
visually enough.
CommandInset (like InsetMathRef) does have cells, but they are hidden
(only for storage). Therefore the default InsetMath::markers() method
mistakenly added markers. In practice, the markers were never active
(since the cursor cannot go into the inset), but some space was
reserved for them.
The enum values BEG_MACRO/END_MACRO and BEG_AR/END_AR are replaced by a
single BEGIN/END pair.
The MathRow code now only knows about insets and math arrays.
New hooks (before|after)(Metrics|Draw) are run by the MathRow code
as needed. They are actually also used internally by the MathMacro
code.
The gain is that most traces of explicit macro handling (and
the MathRow::Element::macro member) have been removed from MathRw.cpp.
The next step will be to extend the tokenizing process to allow for
linearizing insets other than macros.
* Convert the kerning into a proper right margin for mathnormal, mathscr and
mathcal (fonts with \fontdimen2 == 0 as per rule 17 from TeXBook).
* Simulate the fact that characters in mathnormal fonts have a 0-width left
bearing.
* Implement subscript positioning in the case of rule 17 using negative italic
correction (kerning_).
Add a pixel gap around boxes.
When a box is invisible, its width should be null (but keep the weight
to avoid drawing problems (think empty sqrt in a macro).
