ad5548cfe3 Fixes to input method handling
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.

a3868e40a4 Set caret height correctly for cells inside math rows
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.

90cfe4ec3b Adapt caret height to context in mathed.
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.

7bcb78a778 Better mechanism for setting cell cell height
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'.

503c7c1688 When inserting math inset, put cursor selection in the correct cell
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.

9296344b9a Kill macro mode when using LFUN_ESCAPE
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.

68614e9783 Do not draw inactive math corners when they have mathbg color
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.

16af6e7c50 Implement display of roots more faithfully
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.

02028c0b12 Move some Cursor methods to CursorData
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.

6503073070 Fix math mode for InsetMathMacro on output
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

- Use \linewidth instead of \columnwidth because the former will adapt
  to the reduced horizontal width in list environments, avoiding shifting

efc7359015 three-stage drawing: add a nodraw stage
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.

e30f3d76d2 Bulk cleanup/fix incorrect annotation at the end of namespaces.
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.

f1dd80f464 Proper GUI feedback for leqno option
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

a48581f48c Linearize macros in box edit mode too.
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.

9a013637bb Experiment: limit size of strings read from lib/symbols
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.

6763301c05 Better fix for cursor in "blue box"
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.

89662a6852 Re-implement math markers logic.
The goal of this patch is to be able to properly remove the space
needed for markers in the case of insets that are inside macros and do
not need these markers. This was attempted at 9a9a6a8, but did not
work reliably.

To this end, the following simplifications are made:

* instead of drawing its own markers, each inset has a virtual method
  marker() which prescribes either NO_MARKER, MARKER (normal bottom
  marker) or MARKER2 (top and bottom marker). All explicit calls to
  (draw|metrics)Markers(|2) are removed.

* the space necessary for the markers is now counted in the
  before/above margins in the row structure. Therefore painting will
  not happen at (x + 1, y), but just (x,y).

* the methods drawDecoration are removed.

* the helper methods InsetMath::(draw|metrics)Markers(|2) are removed
  and replaced by a new function drawMarkers in MathRow.cpp.

Now the marker type is kept in the MathRow::Element object (and set to
NO_MARKER in not editable context) and the marker is accounted for in
MathRow::(metrics|draw).

Moreover, the extra pixel for the marker is taken on the before/After
space if possible. The marker will only require extra space when
before/after is 0.

See comment 168 of #8883 to understand what issues are fixed.

a single DUMMY (they can be recognized from their class).

e8f480e7c2 Fix display and output of math macros with optional arguments
This is a long standing issue, present since the new math macros
inception in version 1.6. It manifests as a display issue when a
macro with optional arguments appears in the optional argument of
another macro. In this case the display is messed up and it is
difficult, if not impossible, changing the arguments as they do not
appear on screen as related to a specific macro instance. It also
manifests as latex errors when compiling, even if the latex output
is formally correct, due to limitations of the xargs package used
to output the macros. Most probably, both aspects have the same
root cause, as simply enclosing in braces the macro and its
parameters solves both issues. However, when reloading a document,
lyx strips the outer braces enclosing a macro argument, thus
frustrating this possible workaround.

This commit solves the display issue by correctly accounting for
macros with optional arguments nested in the argument of another
macro, and circumvents the xargs package limitations causing errors
by enclosing in braces the macros with optional arguments appearing
in the argument of an outer macro when they are output. This means
that when loading an old document with such macros and saving it
again, the macro representation is updated and will have these
additional braces. However, as such braces are stripped by lyx on
loading, there is no risk that they accumulate.

Also fix a small inefficiency: always prefer:

over:

  Changer dummy = pi.base.font.changeShape((currentMode() == TEXT_MODE)

The former only records and restores a value when the condition is satisfied,
and does not cost anything otherwise.
