texstring is a pair of a docstring and a corresponding TexRow. The row count in
the TexRow has to match the number of lines in the docstring.
otexstringstream is an output string stream that can be used to create
texstrings (i.e. it's an odocstringstream that records the TexRow information
and let us extract a texstring from it).
texstrings can be passed around and output to otexstream and otexrowstream,
which produces an accurate TexRow information by concatenating TexRows.
Note that the lyxrc.document_path variable corresponds to what we
call the "Working directory" in the GUI preferences dialog.
Setting document_path to "." makes it so when LyX is started from a
directory, that directory is the default path for many of LyX's
operations, such as the following:
- new file, new from template
- adding a custom BibTeX file
- GUI compare dialog
- local layout button in document settings
- external material file browser
- graphics browser, include browser
The best guess for where the user wants to save or find files is the
directory the user started LyX from. Before, the default was always
the home directory. If desired, the old behavior can be restored by
changing the default path in Preferences > "Working directory".
This commit takes advantage of 9b64d7bd, which allows the use of a
relative path for path preferences.
The limit of 10% is used in both getStatus() and dispatch() to set a
minimum zoom level. Having it centralized makes the code more
readable and makes changing the minimum less error-prone.
* New virtual functions leftMargin() and rightMargin() to get rid of
drawWithMargin()
* Factor and rewrite code for borders.
* Fix several offset calculations.
Known issues:
* Borders of multicols look too good and do not correspond to the pdf
output. (non-regression)
* Bounding box for Hull (Regexp) not pixel-perfect.
* Bounding boxes of Diagram, XYmatrix, are too tight when there are
borders. Also border should be disabled. (non-regression)
A better solution would be to entirely get rid of this borrowed pointer with
unclear lifetime, but this requires to introduce a new signal for when the
buffer view attached to the GuiView has changed.
Until now this was not done for essentially two reasons. The first
one is that local switches are used for short text insertions, so that
they are unlikely crossing environment boundaries. The second one
is that if we have to close a language at the end of an environment
we would be missing the right termination command. As this last
issue can be overcome by simply storing in the stack the current
nest level with a sign denoting the kind of switch, there is no
reason anymore not to track also local languages switches.
Also factor out some commonly used constructs in order to improve
readability.
If the document language is opened outside of any environement, we risk
not closing it if no other language switch occurs. Indeed, the stack is
emptied only at the end of an enviroment. We could of course also empty
it at the end of the document, but we would have an unnecessary language
switch.
Trying to spare a few cycles by avoiding computing metrics during
screen updates and export. See also 8f86ee74, 72cf7c8f, and e36a8903.
Guillaume will tell whether this also avoids crashing his documents ;)
Some macros defined in the lib/symbols file are classified are texmode.
But the MathMacro class was missing a currentMode method for returning
this information.
When using polyglossia, lyx was making a real mess when changing
language inside nested insets. The \begin{language} and
\end{language} commands were not well paired such that they could
easily occur just before and after the start or end of an
environment. Of course this was causing latex errors such that
"\begin{otherlanguage} ended by \end{environment}".
There may still be some cases I did not take into account.
TexRow now returns a range {start, end} when looking up a particular row.
Reverse-search now selects the whole range instead of simply moving the cursor.
Add an exception to the conversion of "missing character" warnings into errors.
The PGF package deliberately uses the dummy font "nullfont" to suppress output.
Therefore, warnings about missing characters in "nullfont" are really only warnings.
Also updated the comment: "Missing character" warnigns are especially widespread
in XeTeX/LuaTeX but can also happen with "classical" 8-bit TeX.
Feel free to port this to branch.
The title is changed to "LaTeX (pdflatex) Preview", etc. depending on the
format. The actual default format is computed.
The menu name "Source Pane" is replaced by "Code Preview Pane" to better reflect
its purpose.
When resolving biblatex's xdata references, consider that xdata fields
can contain a comma-separated list of keys, not just a single key like
crossref.
In addition to the classic crossref, biblatex introduces xdata
references in order to source-out common data of entries. Entries
that have "xdata = {somekey}" just inherit all fields from the
respective @xdata entry, if the field is not already defined in
the entry itself (just like crossref, with the exception that @xdata
entries themselves are _never_ output on their own). @xdata entries can
themselves inherit to other @xdata entries (ad infinitum). So you can,
for instance, setup an xdata entry for a book series with series name
that inherits an xdata entry with information of the publisher
(publisher, address). Any book of that series would just need to refer
to the series xdata and add the number.
BiblioInfo now checks, in addition to crossrefs, for such xdata
references and inherits missing fields.
Nte that biblatex also introduces an "xref" field as an alternative to
crossref. We must not care about that, since the point of xref is that
it does not inherit fields from the target (just cites that one if a
given number of refs to it exist)
Do not assume that the /systemlyxdir path prefix in \origin refers
to the system directory of the running instance, but check through
some heuristics what the real system dir is. In this way, a document
in the system dir of any other LyX installation is correctly spotted
and the \origin tag properly updated. For example, one can use an
installed version of lyx to edit a document in the lib/doc dir of a
git repo and obtain the same result as when running lyx in place.
Revert to the strategy used at 8f86ee74 but not using mathedWordList
because it may be still uninitialized at load time. Instead, use the
globalMacros method for getting the same info.
There was a thinko at 8ec91e80, because globalMacros always returns
null for user defined macros.
It may happen that mathedWordList is not still updated at load time,
so we would still be using a bogus pointer. Better fetching the
necessary info from the global macro table.
The math macros system is quite complex. Macros are updated during
metrics calculation, so a missing update is very likely to cause a
crash. This commit tries to assure that they are updated at export
time, which also happens when the table of contents is updated.
Moreover, in order to circumvent a possible missing update, when
a math macro is detected we try to avoid using the sym_ member
of the MacroData class, as it may contain bogus values.
Load required package textcomp.
Replace call to non-existent packages textcyr and textgreek with the backup definition of the commands as done by LyX export.
Do not load marvosym (clash with pifont) (LyX does not load the package either).
Remove invalid command \\ascii.
On export, a macro defined in ERT (or not defined at all) is left
in the same environment it is entered. So, don't explicitly insert
it in an ensuremath environment when it is entered in a textmode one.
From Günter [1]:
the difference is the textcommand for ETB which changed from
{\ascii\ETB} to
0x21a8 "\\ETB" "ascii" "force=utf8" # UP DOWN
ARROW WITH BASE
because the former resulted in
l.513 \ascii
\ETB{}
! Undefined control sequence.

Fix problems revealed by hand-compiling an examining the test samples in autotests/export/Unicode-characters/:
* new definitions
* fixed definitions
* "force=utf8" when required
* some IPA symbols fail without the "extraipa" package
* fix direction of "textcommaaboveright"
A math-mode command entered in a text-mode environment is wrapped
in an ensuremath inset, as well as a text-mode command entered in a
math-mode environment is wrapped in a text inset. Who doesn't like
the extra insets can always dissolve them and rely on the wrapping
performed on export.
If the first character in the first cell of an aligned math environment is
'[', and the environment does not use top or bottom vertical alignment,
then LyX did write the '[' unprotected so that it got misinterpreted as
optional argument, both when reading the .lyx file in LyX and when reading
the .tex file in LaTeX => data loss!
The fix is to output an empty optional argument in this case, which is
interpreted as default alignment both by LyX and LaTeX. It would also be
possible to output \[ in the first cell instead, but this would be more
difficult to implement.
The \multicolumn command allows to set vertical lines for individual rows.
These are not yet displayed, but if they are supported one day, the code in
a27ff13663 needs to be adjusted. This change hints at the adjustment.
This is a fixup to commit 39329935. The two fixes are
* add forgotten offset `y' when drawing the line
* in order to have a continuous vertical line, draw from the offset of
the previous row.
Fixes bug #10363.
The window title is built from the current file name and its
mofidication state. We use our own code instead of the automatic title
bar provided when windowFileName() is set because
1/ Qt does not keep the full path name
2/ Qt does not yield a nice application name
The "read only" and "version control" status are shown in the status bar:
* for read only we use the tab read only emblem (with the right size)
* for version control, we show the name of the backend (using a new
vcname() method of the backend).
The iconText() of the view is not updated anymore, since this is
deprecated in Qt5.
Now the external material file dialog shows the file types defined in the
template again. Before this fix it did only show "All files (*)".
I don't know what the old syntax was supposed to do or whether it ever worked
with boost::regex, but with std::regex the new one is correct.
As noted in the log, this commit was a bit radical and needs some
adjustments (which was expected, actually).
Let InsetText do their own background drawing.
Fixes bug #10359.
Before, it could have been the case that
lyx -e pdf2 file.lyx
had exit code 0 even though file.lyx includes a file that exits with
error. If compiled in the GUI a warning was given, but from the
command line exit code it would seem there was no problem. The exit
code for this case is now non-zero and the word "Warning" is now
removed from the message because it should be treated as an error.
An exception is thrown from InsetInclude and is caught in
Buffer::makeLaTeXFile() and added to the error list.
The (similar) use case at #8840 is also fixed by this commit.
buffer-zoom-out can actually zoom in (by giving a positive number as
the argument), so it should only be disabled at the minimum zoom
level if it is indeed zooming out.
Similarly, buffer-zoom-in can zoom out, so it should be disabled if
the user is at the minimum zoom and it is called to zoom out.
This commit amends 8884c404.
Replace the member reference to FuncRequest in Action.cpp with a
shared_ptr. Compared to copying the FuncRequest, the shared_ptr has two
advantages:
* Recreating the menu each time creates a lot of new actions, so we avoid a lot
of copies.
* FuncRequest can remain forward-declared in Action.h.
The field prettyname can accept Unicode and therefore must be parsed into a
docstring.
Little simplification of the code on the way.
* For other fields, either a validator should be set to prevent non-ascii input
in the preferences, or they should be transformed into docstring too.
When breaking paragraph in an empty top-level paragraph, nothing
happens on screen but yet there is an undo step because the layout is
reset to what it already was.
Avoid this case.
Fixes bug #10089.
Single quotes are special to our parser and must be either escaped or
quoted if they are part of a filename, otherwise they are stripped out.

Since we process layouts sequentially, we export LaTeX code for the
title once we arrive to a layout that has InTitle false. If the
document then later has a layout with InTitle true, we do not
(currently) go back to add it to the title and just output it
in-place. We previously warned with LYXERR0, but since this can
cause missing or unexpected output we now warn in the GUI.
For more information, see the following lyx-devel thread:

Now by default all insets paint their own background when needed. This
means that 63cf3297 and part of 9940acc5 can be reverted.
To avoid extra painting, background drawing is disabled for
InsetCommand and InsetCollapsable. These insets draw background as
part of their normal drawing activity.
This will avoid drawing artifacts with InsetNewpage, InsetVSpace and
probably some others.
Fix assertion with gcc 6: The comparison function must be a strict weak
orderings and not give x < x.
Fix assertion when a custom exportable document format is given a non-ASCII

Use Qt's locale-aware comparison for appropriate sorting.
There was an oddity in the manual that exposed a problem with the
test for the "special case" of an inset all by itself in a pargraph.
If a font change is applied to that inset, we still need to open the
paragraph.
File format change. On format reversion, we need to put some extra code
in the local layout that emulates the 2.3 behavior.
Simply Input'ing the respective layouts is unfortunately not enough,
due to the insertion order.

"lyxclient -g" now calls the just implemented lyx-activate (see
previous commit) after server-goto-file-row. This allows the PDF
viewer to switch to LyX after executing a reverse search.
On Linux and Mac OS, this action brings the LyX window into focus.
Such behavior is not allowed by Windows OS so instead the color of
the taskbar entry is changed to indicate that the window has changed
in some way.
The action is hidden in the shortcuts menu because it would make
sense to assign a shortcut to it. The only way to execute shortcut
would be if the LyX window is already activated.
lyx-activate will be used (see next commit) to allow the PDF viewer
to switch to LyX after executing a reverse search.
* New constant LYXFILE_LAYOUT_FORMAT in src/TextClass.cpp. This determines the
layout format corresponding to the current lyx file format.
* The Local Layout pane is changed so that the "Convert" button does not convert

that the file does not become unreadable with a specified earlier version of
LyX.
* If LYXFILE_LAYOUT_FORMAT == LAYOUT_FORMAT then LyX behaves as before. This is
the value defined in master.

Prevent setRange() from causing a recursive call to scrollTo(). Reduces three
calls of scrollTo() to one call for all scrolling functions of the scroll bar
(e.g. clicking on the arrow, dragging, or clicking somewhere on the scrollbar).
The function is no longer used in LyX's sources (as of the previous
comit, 9b64d7bd) and is thus removed with this commit. Perhaps the
advantage this function had over other path functions we have has
disappeared over time (see e.g. 1a7b7f65).
Before this commit, in the paths preferences tab if you put a
relative path, LyX would convert it behind the scenes to an absolute
path by evaluating the relative path with respect to the working
directory of the LyX instance where the preference change is taking
place. This seems confusing because (1) it is done behind the scenes
(after the preferences dialog is closed) and (2) if the user chooses
to enter a relative path, the safest thing to do is to preserve it
as a relative path, instead of making the assumption that the user
intended for it to be expanded to an absolute path.
An explanation of how relative paths are handled is given at the
bottom of the paths tab. Note that the height/width of the
preferences window is not changed as a result of adding this
explanatory comment because the height of the preferences dialog is
already stretched by other tabs.
This commit improves consistency in the sense that the behavior of
LyX is now the same when a relative path is specified in the
preferences dialog as when it is manually specified in the
preferences file. Before, if the preferences file were manually
edited and a relative path were inserted, the next time the user
made a change to preferences with the GUI (even if the preference
change was a different preference, e.g. instant preview), the
relative path would be silently converted to an absolute path,
evaluated with respect to the working directory of that instance.
Beyond improving clarity and consistency (IMO), this commit allows
for a new feature to be implemented of using relative paths in the
paths preferences. For example, the user may now enter '.' as the
"Working directory" path and now whenever they start LyX from a
directory and create a new file, the default location of the file
will be the directory from which they started LyX, instead of the
user's home directory which is LyX's default and is less intuitive.
No prefs2prefs work is needed because if a relative path were
entered in the preferences dialog before this commit, it was
converted to an absolute path before being stored in preferences. If
a relative path were specified by manually editing the preferences
file, then (unless the path were already automatically converted to
an absolute path by a GUI preferences change, as described above)
the behavior will be the same (the path will be treated as a
relative path).

This commit removes the last use of lyx::support::expandPath() in
LyX's sources.
The Qt documentation states that tabAt() returns -1 if the position
is not over a tab. This behavior has been consistent since Qt 4.3
[1]. This commit's improvement likely makes the code faster in two
ways:
(1) we do not need to loop through potentially all tabs
(2) we only need to look up the tab index corresponding with one
position
posIsTab() is not currently used intensively so no practical gain in
speed is achieved, but it protects against future use.

This is the default behavior of Chromium and Firefox. The main
appeal is that instead of having to precisely click on the 'x' to
close a tab, one can more easily middle-click anywhere in the tab.
The tab is closed if the middle button is pressed on a tab and is
relased on the same tab. After pressing, the user may move the mouse
over other tabs but as long as they move it back to the tab where
they initiated the press before they release, the close will
execute. This is how the feature works in Chromium and Firefox.
Nothing is done if the user middle-clicks on the blank part of the
tab bar. This is consistent with Chromium. Firefox, on the other
hand, opens a new tab. In LyX one can already double-click the blank
part to open a new tab, and in feedback from lyx-users [1] most
expected and desired that nothing be done in this case.

A chunk of code in an event handler seems to be unnecessary to me
because the event that the situation handles never makes it this far
in the event handling hierarchy. I'm not sure why this is, and thus
I'm not sure if this is true in all cases (e.g. Qt version) and if
it will be true in the future so I leave this code for now.
In redoParagraph, this should be done before coping with the insets,
other wise some graphic gliches may occur. This is a better fix for

With the commit cb0c881 we reference XSendEvent in X11-lib

For QT5, this library is pulled by Qt5X11Extras, but
for QT4 we have to add it too.
Spotted by Scott Kostyshak.
For reference, the bug was that quote insets grew bolder because, when
painted over themselves, anti-aliasing made them darker.
It turned out that the fix there created others than were
painstakingly fixed: #7164, #7165, #7174, #7193... More recently, it
created other problems:

* draw background of math macro template when not doing full repaint
* remove hack that grew from #4889 fix.
The default for ZOOM_OUT is -20 from a user perspective. That is,
the following are equivalent:
buffer-zoom-out -20
buffer-zoom-out
The reason for this is that the argument to ZOOM_OUT is treated the
exact same way as ZOOM_IN. The only way they differ is how the
default case is handled.
This commit also clarifies that (1) the argument may be positive or
negative and that (2) the argument is interpreted as percentage
points, not percent.

is output when a branch is NOT activated. Fixes bug #7698.
At the moment, inversion is controlled through the branch settings

The differentiation of "xetex" and "platex" is not needed here,

it can/should get its information otherwise.

selection request cures the issue. The cmake part is by Kornel.

dealing properly with the paragraph separator tag.
We really need to use that tag as a kind of general marker for which
tags we're responsible for in a given paragraph and which tags we are
not. So the changes to InsetText.cpp use the tag as that kind of marker.
Note that, as of this commit, the User Guide again exports without any
kind of error. I haven't yet checked the other manuals.
This fixes bug #8022.
A window manager could be configured such that to maintain a certain
stack order for the windows. It would be annoying that opening a new

loading a file through the lyx-server.
The line felt too thin.
Note: I am still sceptical with the principle of an increase at the rate of
1/200% instead of 1/100%.
Also, I am sceptical with changing painting dimensions to int when Qt supports
doubles for everything (see e.g. 463bd17d). If the goal is to force
integer-width solid lines then one could try to disable antialiasing on Qt's
side.
I think the painter should move in the other direction, towards more doubles and
fewer ints. For instance, for Hi-DPI, Qt could probably take advantage of the
increased precision even without AA. (Then one would have to fix the problem
regarding uneven lines, mentioned in the above commit, in another fashion.)
* Underline or strike through the label as if it was text (it is).
* Strike through deleted InsetText, but let RowPainter handle the case of
non-MultiPar text insets.
* Change the colour of the frame as a cue, unless its colour is customised (not
Color_foreground). (Essentially do the border of CharStyles like Tabular does
it already.)
* The change info needs to be reset when entering InsetText. Otherwise labels
are painted with the change of their n+1-th parent.
It is not possible to use opacity effects (such as drawing an antialiased line
to strike diagonally through an inset), until the painter is fixed so that it
does not redraw repeatedly over the same spot (otherwise, the usual aritfacs
appear).
For now, pixellated lines are OK.
* Justification and nicer line breaks.
* Much nicer tooltip for lists of bibliographical references.
* Removed unnecessary iterated copies of the string buffer in
InsetText::ToolTipText() which looked bad. This function used to be costly
(cf64064), maybe it is quicker now.
After the previous commit, tooltip in the outliner are formatted automatically,
along with the other tooltips. A previous commit had already removed the
expensive call to tooltipText() that, although it gave a better rendering, was
very expensive (cf64064). This patch finishes to remove the custom tooltip
from the model data in the outliner.
(It would be nice to reintroduce a tooltip based on tooltipText(), but there
seemed to be a consensus that in that case one would prefer a less expensive
approach that computes the tooltip on the fly.)
* The tooltips in the list of modules now include the names of the modules.
* The tooltips of modules more consistent across the widgets.
* Sort the list of modules according to the locale (i.e. "É" comes before "F").
* Replace a hand-made sentence boundary finder by Qt's.
* New function formatToolTip(QString):
Format text for display as a ToolTip, breaking at lines of a certain
width. Note: this function is expensive. Better call it in a delayed manner,
i.e. not to fill in a model (see for instance the function
ToolTipFormatter::eventFilter).
* Install a global event filter that formats tooltips on-the-fly
Inspired from
3793fa09ff
but much improved.
When is formatToolTip called automatically? Whenever the tooltip is not already
rich text beginning with <html>, and is defined by the following functions:
* QWidget::setToolTip(),
* QAbstractItemModel::setData(..., Qt::ToolTipRole),
* Inset::toolTip() (added in one of the subsequent patches)
In other words, tooltips can use Qt html and the tooltip will still be correctly
broken. Moreover, it is possible to specify an entirely custom tooltip (not
subject to automatic formatting) by giving it in its entirety, i.e. starting
with <html>.
This is the well known file locking problem: The TempFile class keeps the

We need to invalidate the BibTeX cache when undoing or redoing. I do
not like having to do it for every undo or redo. We should only have
to do it if we restored or deleted an InsetBibTeX. But there is no
way, so far as I can see, to do it that way. I tried.
The main thing it does is integrate mouse-modifiers into the
FuncRequest machinery. Previously, these had to be passed
separately, which led to some ugly function signatures.
There was also an unnecessary form of the constructor, which
can now be removed.
No change of behavior is intended.
The only exceptions are:
- The purpose of the header is to drag in the used symbol, e.g. unique_ptr.h
- The used symbol is inside a class or a namespace other than lyx
The reason for this is that global 'using' statements effectively forbid to
use the used symbols in any other namespace in the whole program, since simply
adding or removing an #include of the corresponding header subtly changes the
name lookup. The namespace lyx is sort of global, so it should not have these
statements either.
Maxima uses \it as a markup for multiletter variables. However,
it has been reported that since texlive 2016 using \it in math

output of tags until we know they're needed. In the case of HTML
tables, empty cells should of course be output, so we need to force
the tags to be output.
The external date inset was implemented as a demonstrator for external insets
in general. It was never intended for production code. Now that we have several
external insets defined we do not need the demonstrator anymore. This fixes
bugs #4398 and #9948.
This was dead code that did never work, and most of it was boilerplate that
you can steel in 15 minutes from any existing math inset. Apart from that it
did contain a pointer to InsetXYMatrix which would create the same problems
we saw with the macros.
This requires to change many docstrings into std::strings. The logic behind that
is that they represent a fixed set of math fonts, and therefore “string” means
here “poor man's enum” rather than text (this is consistent with MetricsBase).

35,3% BufferView::updateMetrics()
-> 27,2% InsetMathHull::metrics
-> 0,4% FontSetChanger::FontSetChanger()
47,5% BufferView::draw()
FontSetChanger::FontSetChanger() is made 41x less expensive (with reference
BV::draw()) just by removing this conversion. The remaining 0,4% could be
squished by replacing the strings with a proper enum, but this is premature. Of
course, this only treats the symptoms: there is no good reason that this
function is called 45500 times over the time of 40 repaints.
Replace the manual manipulation of a stack of RowEntries with a Changer
function. When I introduced the stack of RowEntries, I did not know about the
Changer mechanism.
* Inset::canTrackChange() had two meanings: can it deal with change tracking?
Will it paint its own CT status? The latter information is now given by
Inset::canPaintChange().
* Line thickness computation is moved from RowPainter to MetricsBase.
* Painting function for Changes moved to lyx::Change. (One new, that strikes
diagonally.)
RefChanger temporarily assigns a value to a non-const reference of any
kind. RefChanger provides a flexible and uniform generalisation of the various
scope guards previously derived from the old Changer class in MetricsInfo.h.
As before, a temporary assignment lasts as long as the Changer object lives. But
the new Changer is movable. In particular, contorsions are no longer needed to
change a private field. Special code can be moved into the appropriate classes,
and it is no longer necessary to create a new class for each specific use.
Syntax change:
FontSetChanger dummy(mi.base, value);
-> Changer dummy = mi.base.changeFontSet(value);
New function for generating arbitrary Changers:
Changer dummy = make_change(ref, val, condition);
Bugfix:
* Fix the display of \displaystyle{\substack{\frac{xyz}{}}} (missing style
change).
The command 'lualatex' can produce a DVI with the option
--output-format=dvi
It is best to keep things as is because it is better to guess a PDF
than to guess a DVI (we do not use that feature of the 'lualatex'
command internally; we use 'dvilualatex' instead). However, we
should ideally get this information in a more robust way.
Thanks to Günter for pointing this out.
XeTeX with TeX fonts is only safe with ASCII input encoding (see #9740)
and we therefore force "ascii" when exporting with XeTeX and 8-bit TeX-fonts.
However, "utf8-plain" is a "power-user" option, which allows to switch off LyX's
encoding of the LaTeX file:
keep this also for "XeTeX with TeX fonts".
The user is responsible to ensure all characters can be processed and are
correctly shown in the output. The provided test sample shows the problems
with this encoding without special measures (like loading fontspec in the
user-preamble or a document class).
Boost.Signals is deprecated. This fixes bug #9943.
The only thing left to do is to rewrite (or get rid of) the boost -mt test
in config/lyxinclude.m4 not to use signals anymore.
It is no longer needed to create fake copy constructors and assignment and to
deal with deletion by hand, thanks to unique_ptr, the inference of move
constructor and assignment operator, and the compatibility of standard
containers with movable objects.
Two better ways of making a class non-copyable in C++11:
* Store the p. impl. in a unique_ptr (for the cases of classes with p. impl.),
or:
* Define publicly the copy constructor and assignment as deleted
Lots of other classes could be cleaned up in this way.
This is a mechanical replacement. For now it seems that unique_ptrs are
essentially used for exception-safety. More could certainly be done to clarify
pointer ownership in general.
The parameter passed to allowDisplayMath will need to be copied, so it
made sense to pass it by value. Since Coverity complains about that,
the code is rewritten to make the copy explicit.
This code is signalled as a copy and paste error, but it is a false
positive.
According to the documentation, adding a comment starting with
// coverity[name_of_error]
should be enough to flag the false positive.
As discussed on the list. If no C++11 compiler is found configuration stops
with an error. There are now unneeded parts of boost, the will be removed in
a second commit.
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.
It turns out that it did not take off since introduced in 2011. It is better to remove it and the associated boost headers (extract.sh was run against boost 1.60 to do the update).
Since we will move away from several boost classes when transitioning to C++11, it is good to start by removing lesser used ones.
It is easier to use instead getVectorFromString for the use we have of this tokenizer. The two places are environment.cpp (path stuff) and qt_helpers (file fileters). The new code is much shorter.
This allow to remove boost/tokenizer.hpp and friends from our boost tree.
Some headers contain
class Foo;
whereas there is no class Foo.
The list of class statements is given by
classes=`git grep '^\(class\|struct\) [a-zA-Z_:]*;' src | sed 's/^.* \(.*\);/\1/'|sort -u`
The ones that are useless are:
for c in $classes ; do grep -r "\\<$c\\>" src| grep -vq '^[^:]*:\(class\|struct\) [a-zA-Z_:]*;' || echo "$c"; done
Those two functions used two different hackish and buggy
implementation to know when the function is disabled. Replace that by
asking the containing inset whether it accepts inserting display math
inset.
Fixes bug #10033.
When in a tabular cell, "this" is just a lone InsetText, while cur.inset() is the whole tabular. This makes a big difference, especially when one wants to count cells.
Fixes bug "9954.
Compiling different parts of the sources with different WINVER may lead to
subtle and hard to detect problems. Better use the same value everywhere.
The existing error message suggests that this was wanted anyway, and it
fixes a compiler warning when cross-compiling for mingw on linux. Our code
does not require a specific value, only a minimum value of 0x5000, which
means the resulting executable will require at least Windows 2000.
Only the ones I understand (DWORD is always unsigned). There are more:
../../src/Server.cpp: In member function ‘bool lyx::LyXComm::pipeServer()’:
../../src/Server.cpp:280:10: warning: enumeration value ‘CONNECTING_STATE’ not handled in switch [-Wswitch]
switch (pipe_[i].state) {
^
../../src/Server.cpp:347:8: warning: ‘success’ may be used uninitialized in this function [-Wmaybe-uninitialized]
&& status == pipe_[i].iobuf.length()) {
^
Use the standard way to check for the resource compiler, as e.g.
libtool does it: AC_CHECK_TOOL does already provide some cross compiling
magic, and we do also get an error now at configure time if windres is not
found.
"Output changes" alters the preamble even in the absence of tracked
changes. Therefore, not being able to notice when it is activated can possibly
yield hard-to-debug compilation failures.
The windres program is typically not called windres for cross compilation.
Now you can call configure with the argument
WINDRES=x86_64-w64-mingw32-windres
in order to use the windres program on a standard debian installation.
The included iconv should not be used on Linux or OS X, but (depending on
local configuration) it might be needed for crosscompiling a mingw target
from Linux. Now the user can choose whether to use the included iconv or not.
cmake does already support that.
eilseq.m4 was taken from the original libiconv 1.14 package.
On mingw-w64, long long (64bit wide) is larger than long (32bit wide).
Therefore we need some more specializations for string, docstring,
otextstream and << overloaded ostream functions. The configuration code
is by me, the source code changes by Shankar Giri Venkita Giri (bug 10053).
This is needed for warning-free compilation with mingw-w64, and does not hurt
for other build configurations. Patch by Shankar Giri Venkita Giri (bug 10053).
The included zlib should not be used on Linux or OS X, but (depending on
local configuration) it might be needed for crosscompiling a mingw target
from Linux. Now the user can choose whether to use the included zlib or not.
cmake does already support that.
zconf.h.in was taken from the original zlib 1.2.8 package. The generation of
zconf.h was made equivalent to the one generated by cmake.
(#8738)
For efficiency, we add a new flag to the buffer indicating when changes are
present. This flag is updated at each buffer update, and also when explicitly
requested via a dispatch result flag.
If we do not do that, it is not possible to position the cursor after
a long inset with the mouse.
To do this, it is necessary to add the pit information to the Row
object. This is a good idea in any case, and will allow to simplify
some code later on.
Fixes bug #10094.
The timer logic introduced to solve bug #7138 was not entirely reliable; in
particular it resulted in spurious updates (noticeable by the treeview
collapsing just after one opens a branch, in particular).
This commit cleans up the timer logic. I followed the original design decision
of having an immediate update followed by a delayed update. Now the updates are
appropriately compressed and done after a delay of 2s (as can be noticed with
the treeview still collapsing, unfortunately, but after a more predictable
delay...).
4d1ad336fixed#9754 but caused perf issues by cancelling the gains of having a
timer (introduced after #7138). This introduces in GuiToc::enableView() a
lightweight check of whether the widget should be updated. The logic is inspired
from GuiViewSource::enableView().
When document settings are modified, a command
inset-forall Branch inset-toggle asign
is run to open as needed all branches. At the end of the said loop,
the cursor is reset to where it was. However, the cur_after undo
element member is not set because it already had a value.
To make this work as expected, it is necessary in LFUN_INSET_FORALL to
reset the cursor before ending the undo group and to insert a dummy
recordUndo call.
Fixes bug #10097.
Deriving from std::vector to provide helper functions appears a touch
excessive. Use typedef instead and move helper functions to the base class. New
header Toc.h provided to replace forward-declarations.
Remove TocIterator which is useless.
The old name conflicted with the newly introduced Inset::isTable.
Now the meaning is as follows.
* Inset::isTable() is true when the inset is composed of lines and columns
* InsetMathHull::allowsTabularFeatures is true when the current type of hull allows for tabular-like functions.
While a one paragraph large collapsable inset (containing for example a tabular) could be very wide and trigger horizontal scrolling, the code that makes collapsable insets wide when they contain several paragraphs would actually make them narrower in this case.
Typical example is a wide tabular and a caption in a table float, where horizontal scrolling would not trigger.
The purpose of this custom widget is to allow the use of a QToolBox in a limited
area. The stock QToolBox does not provide a minimum size hint that depends on
the size of the pages; it assumes that there is enough room. This subclass sets
the minimal size of the QToolbox. Without this, the size of the QToolbox is only
determined by values in the ui file and therefore causes portability and
localisation issues. Note that the computation of the minimum size hint depends
on the minimum size hints of the page widgets. Therefore page widgets must have
a layout with layoutSizeContraint = SetMinimumSize or similar.
inset-select-all has 3 levels
1. select current cell
2. select all cells
3. select inset from outside.
The second level makes sense for tables (text and math), but not for things like a math fraction.
Introduce a new method Inset::isTable() that allows to detect this case properly and skip level 2.
This is done by implementing the clickable method. It is not possible yet to have the usual left and down arrows, because Qt does not implement them as far as I can see.
Factor the code that triggers row/column selection and fix the logic. Now it is possible to select also at the right of the tabular inset.
When several bufferviews exist for the same inset, the data that depends on the view width have to be BufferView-dependent. While this is the case for several mutable members of InsetCollapsable, some were missing.
This commit makes button_dim_ (renamed from button_dim) and openinlined_ bv-dependent.
Get rid of the hitButton function.
Remove the bv-independent geometry() method and implement editable() explicitely instead.
Fixes bug #9756.
"echo -e" is definitely not portable. Use a plain loop instead.
Also use the automake silent rule mechanism to make the generation of monolithic source files visible.
When the box has a special width, one should not consider that as a fixed width. Otherwise, due to implementation quirks, the width will be set on screen as 1 inch.
A better solution would be to actually set the width by taking in account the contents width, height ans total height. This is not very difficult, but I do not know whether it would workout well in the work area.

Ask the user for removing bindings when using the "restore" button (#9174).
Fix the already-bound-key detection logic.
Don't forget to trigger the search when initializing the search LineEdit with
its former value.
Remove in particular all comparisons < and >= involving HullType.
Add a guard to make sure that mutate() only operates on types it has been
designed for. Then I figured I could use this new knowledge to give feedback
when math-mutate is not implemented via getStatus(). (To test this, insert a
regexp in Advanced Search & Replace and try to change it into a standard
equation via the contextual menu.)
AMS align environment should have some spacing between odd and even columns.
Add a new virtual method displayColSpace() to InsetMathGrid, InsetMathHull and
InsetMathSplit.
A longstanding problem... (related: #1861)
The columns in AMS math environments have a fixed alignment (colAlign() in
InsetMathGrid.cpp). We set this alignment for display (Georg's
displayColAlign()) in InsetMathHull and InsetMathSplit. This is done according
to tests and documentation for the various environments.
There is also some mechanical code factoring via colAlign().
Finally, I disable setting the horizontal alignment in InsetMathSplit, which has
no impact on the LaTeX output, and has no longer any impact on the screen. (As
for vertical alignment I discovered that it was in fact customisable for
\aligned & friends! I hope that the more faithful interface will let other
users discover that too.)
The offending code appears to have been introduced a long time ago. My
understanding is that it is no longer relevant. Notably, it only appears on copy
and not on cut, which tells us that: 1) it should be safe to remove it, 2) we
should remove it for consistency.
With Qt 5, our code did not correctly detect when icons were
available and thus tried to use nonexistent icons.
QIcon::hasThemeIcon(theme_icon) returns true when theme_icon is
empty. We now rely on the behavior that QIcon::isNull() returns true
if the icon is empty.
The same code is used with Qt 4 and Qt 5.
This is used when scaling graphics previews. It is also used on a rare occasion
to scale instant previews when the user's configuration mixes low-dpi and
high-dpi monitors (#10114).
With this change, it becomes possible to run the following commands:
inset-forall Separator:latexpar char-delete-forward
inset-forall Separator:parbreak inset-modify separator plain
The first one deletes all latexpar separators. The second one turns parbreak
separators into plain separators. This is safe, flexible, and avoids adding a
new LFUN.
2.1.x allows some document settings to have negative values where
2.2.0rc1 does not (because of the bug fix at 9e166088). If a user of
2.2.0rc1 opens a document from 2.1.x that contains one such negative
value, it will appear as though no change to the document settings
can be saved because 2.2.0rc1 treats the document settings as
invalid immediately on opening the dialog. Further, unless the user
manually goes through each tab they will not see the red text next
to the input that is now considered invalid. This could lead to
confusion for users. One example of such confusion is [1].
The following settings now allow negative values, which is
consistent with 2.1.x. Negative values in these settings do not lead
to LaTeX errors:
- Text Layout tab: the two line edits enabled with "Custom"
- Page Margins tab: all eight line edits
The following settings are not changed by this commit, so they now
(with 2.2.0) do not allow negative values that 2.1.x allowed. This
change makes sense because negative values lead to LaTeX errors in
these cases:
- Page Layout tab: the "Height" and "Width" line edits, which are
enabled when "Custom" is selected

An undocumented behaviour of QClipboard::mimeData() is that it can fail on
windows due to the specificities of the windows API that allow a race condition.
In particular it seems that querying the clipboard as soon as the dataChanged()
signal is received favourises this race condition.
Thanks to Trac user bquistorff for the explanation and a proof of concept patch.
This was a regression of 8aa37c43. I did not take into account that end_pos
could be -1, so the code that checked whether a pair of braces needs to be
inserted between two hyphens did not work for that case. Now we check for
the length of text_, which should be done anyway, and only take end_pos into
account when it is not -1.
http://thread.gmane.org/gmane.editors.lyx.devel/161725
These wms have trouble with the fix at b5a2f1c7, probably more precisely with
the trick to force the calculation of the actual sizes before the display
(layout->invalidate() and the code around it).
This patch gets rid of the code that forces the calculation. As a consequence,
the minimum sizes are again incorrect the first time the window is shown. They
are only correct the second time the window is shown. Now here is the trick: LyX
remembers the sizes of windows between sessions. Therefore, as soon as the good
minimum size has been set, the good size is remembered for the next
session. Thus, in the following sessions, even though the minimum size is
incorrect the first time, the dialog still opens with the good size. So the user
does not see the problem in practice, apart from the very first time.
This is meant as a temporary workaround.
* provide GuiApplication::typewriterSystemFont() to get a fixed font consistently
* enlarge fixed font on Mac because of the too small default Qt system font
* use it in source pane, progress view, log view and document preamble editor
Regression at cfeddb929. If a flex inset has no layout upon saving (e.g. if a
module has been deleted) then its name became lost. This checks whether the name
resolution, introduced with the ObsoletedBy tag, comes back empty-handed (which
it will if the layout is not defined). In this case, we do as was done before
cfeddb929.
In addition, the use of support::token to strip "Flex:" off the beginning of the
name introduces a regression if somebody used a name containing ":". This
replaces it with support::split.
This is the same as the parbreak separator and is represented on screen
as the old parbreak. Old parbreak separators are converted to latexpar
separators when they are used for introducing blank lines in the
latex output rather than for separating environments.
Instead, parbreak separators are now represented on screen by a
double line. In essence, latexpar and parbreak separators produce
the same output but are represented differently on screen.
The context menu does not account for latexpar separators and only
"true" separators can be turned each into the other one.
7b1107d7 introduced the following inconveniences which are regressions to 2.1:
* The citation dialog can open with vertical scroll bars in the options
* The citation dialog can open with horizontal scroll bars, especially if the
translated text is longer than the original text (e.g. in FR)
* Resizing the dialog is inconvenient because it increases the gap between the
options. This is unlike before when the dialog could let us see more of the
reference list when enlarging.
This is because the QToolbox that the above commit introduced is not natively
aware of the sizes of its page sub-widgets. The widget is not conceived for this
use, where the space is scarce.
Geometry values provided in the ui file (automatically computed by qtcreator I
suppose) somehow gave the illusion that it worked, but relying on such values is
not portable : it does not take into account the specific theme, font sizes and
localization. This explains why it failed on my side and will probably fail in
other settings too.
Luckily, there is a simple way to make QToolbox suitable for the current use,
which is to add the "missing link" which computes its size based on the minimal
sizes of its pages. The result looks very nice and intuitive. It solves all the
aforementioned issues.
The term LongTable has been deprecated and moreover the renaming makes the interface easier to the eye.
File format updated to 507. (conversion based on jamatos patch)
Layout format updated to 60.
tex2ylx tests updated.
Document EmbeddedObjects.lyx has been updated.
There are two regressions that are fixed here:
* empty rows at the end of a paragraph (think after newline at end of
paragraph or empty line in Verbatim) do not have an end-of-par
marker. This is fixed by removing the early return in breakRow and
letting the whole function be executed. This requires to relax an
assertion in Paragraph::fontSpan. It makes sense here to query
position at the end of the paragraph.
* a newline at the end of a paragraph will be followed by and
end-of-par marker. This is fixed by skipping the end-of-par marker
when a new row has been requested.
The context menu of newline insets was completely greyed out if one clicked
at the right of the inset. Thanks Scott for finding this. The fix is to undo
the cursor movement also for insets without settings, but with a context menu.
According to callgrind, the time taken to display the symbol dialog is spent in
updateSymbolsList. No longer translate strings for every symbol. This speeds
it up more or less by a factor two.
The stmary font has an unusual large descent that was causing a large
gap between lines in the math delimiter dialog because of the \llbracket
and \rrbracket delimiters. The solution is to force Qt using the same
size for all elements of the QlistWidget widget instead of letting it
compute the size of each element.
When a row is broken by for example a display math inset, it is
possible to put the cursor at the end of the previous line using the
boundary setting of cursor.
For newline insets and separator insets, we want to force the cursor
to be before this inset. Also, in the other cases, do not force
boundary property (effectively reverts part of f29e7803).
* breakRow: remove wrong condition that would silently eat the contents of the
paragraph when the window is narrower than left margin
* breakRow: make sure that there is at least one element in each row
* breakAt: when force-breaking a row element, make sure it is not empty. Doing
so may create empty rows and therefore a endless loop.
Fixes bugs #9962 and #10001.
The existing code already avoids merging with typewriter font, but it does not work with LyX-Code, where the typewriter family is inherited. Therefore it is Cursor::real_current_font that must be tested.
Fixes bug #9987.
