The algorithm used for breaking a paragraph in LaTeX export is changed
for avoiding spurious blank lines causing too much vertical space.
This change is tied to the introduction of a new inset (with two
different specializations) helping in either outputing LaTeX paragraph
breaks or separating environments in LyX. Both of the above goals were
previously achieved by the ---Separator--- layout and can now be
accomplished by the new inset in a more natural way. As an example,
after leaving an environment by hitting the Return key for two times,
a third return automatically inserts a parbreak inset, which is
equivalent to the old separator layout, i.e., it also introduces a
blank line in the output. If this blank line is not wanted, the
parbreak separator can be changed to a plain separator by a right
click of the mouse. Of course, an environment can still be separated
by the following one by using the Alt+P+Return shortcut (or the
corresponding menu key), but now the plain separator inset is used
instead of the old separator layout, such that no blank line occurs in
the LaTeX output.
Old documents are converted such that the LaTeX output remains unchanged.
As a result of this conversion, the old separator layout is replaced by
the new parbreak inset, which may also appear in places where the old
algorithm was introducing blank lines while the new one is not.
Note that not all blank lines were actually affecting the LaTeX output,
because a blank line is simply ignored by the TeX engine when it occurs
in the so called "vertical mode" (e.g., after an alignment environment).
The old ---Separator--- layout is now gone and old layout files using it
are also automatically converted.
Round trip conversions between old and new format should leave a document
unchanged. This means that the new behavior about paragraph breaking is
not "carried back" to the old format. Indeed, this would need introducing
special LaTeX commands in ERT that would accumulate in roundtrip
conversions, horribly cluttering the document. So, when converting a
modified document to old formats, the LaTeX output may slightly differ in
vertical spacing if the document is processed by an old version of LyX.
In other words, forward compatibility is guaranteed, but not backwards.
* disable branch-add-insert in pass thru paragraphs
* when it is not possible to input a quote inset, insert a single
ascii quote when argument to quote-insert is "single"
* handle "mathspace" dialog in Text::getStatus
* disable insertion of newline inset in pass thru paragraphs
* handle "mathdelimiter" and "mathmatrix" dialogs in GuiView::getStatus.
it's easy to use the existing docstring routine, so I've commented
out the string version of lowercase I had introduced. I've left the
code in case someone else needs it later.
the name, in the hyperlink. Fixes bug #8792.
This also fixes a bug discovered while working on this code: The
params passed to GuiHyperlink were never used.
I introduced a regression in c14b9e67 for pasting images:
If an image is on the clipboard both as PNG and HTML with just an url,
but no plain text, pasting would fail. The reason for this was that
text contents was detected (the HTML code), nd preferred, but actually
pasting it resulted in an empty string, since the HTML import could not
handle the url This error was not checked.
The solution is first to try text paste if both text and image content
is present, and then try image paste if the text failed.
each failure.
There are several places I was not sure what to do. These are marked
by comments beginning "LASSERT:" so they can be found easily. At the
moment, they are at:
Author.cpp:105: // LASSERT: What should we do here?
Author.cpp:121: // LASSERT: What should we do here?
Buffer.cpp:4525: // LASSERT: Is it safe to continue here, or should we just return?
Cursor.cpp:345: // LASSERT: Is it safe to continue here, or should we return?
Cursor.cpp:403: // LASSERT: Is it safe to continue here, or should we return?
Cursor.cpp:1143: // LASSERT: There have been several bugs around this code, that seem
CursorSlice.cpp:83: // LASSERT: This should only ever be called from an InsetMath.
CursorSlice.cpp:92: // LASSERT: This should only ever be called from an InsetMath.
LayoutFile.cpp:303: // LASSERT: Why would this fail?
Text.cpp:995: // LASSERT: Is it safe to continue here?
As discussed on the list. No automatic contents detection is done, the user
needs to use the special paste menu instead. I used the new TempFile class
for safe temporary file handling.
The documentation would go into section 2.2 of UserGuide.lyx, but I am not
allowed to edit that document.
This bug was reported against the ubuntu build:

Additionally, some extra code for avoiding double undo entries has
been removed, since this is handled by grouped undo now.
Only the first paragraph in those sequences goes into the TOC, since the environment is merged.
This is needed to handle the forthcoming beamer environments properly in the outliner.
This adds an optional 'set' argument to the language lfun and reintroduces toggling.
Additions by me reintroduce the possibility to reset to the document language via 'language reset' or just 'language'
Currently only basic functionality (our math-tipa functionality plus multipar input). Further enhancements (such as proper unicode input and a specific toolbar) are planned. DocBook and XHTML output also need to be audited.
The lyx2lyx reversion routine surely can be improved (help appreciated), and I don't know tex2lyx enough to handle this file format change.

This also fixes other float-related bugs, such as this:
* select two floats in two consecutive paragraphs and insert a new float around them
=> the master float's caption is put into the lower subfloat instead of below the subfloats.
In the long term, doInsertInset needs a thorough cleanup.

we will be cautious, of course). The problem was that we were issuing
the Buffer::changed() signal before we did updateBuffer(), and this
caused an inconsistency. The idea here is to defer issuing this signal
until we call processUpdateFlags(). We know we need a redraw if we've
deleted a whole paragraph.
This should work properly, so long as checkDepm is called from within
the dispatch mechanism. There may, however, be other paths, and I've
noted one explicitly with a FIXME in Text2.cpp. I've tested a few
different variations, however, and I haven't seen any problems. But if
we do run into problems, we can go ahead and do the update there that we
were previously doing in checkDepm itself.

we've put something into it. (We also don't need to copy an
empty string into it.)

Documentation (and perhaps menu items) need still to be a bit
clarified in order to distinguish the various paste options
for the average user.

- Interpret argument of LFUN_SPACE_INSERT correctly
- Use InsetMathSpace instead of InsetMathSpecialChar for "\ " (bug # 7728)
- Use InsetMathSpace instead of InsetMathChar for ~ (bug # 7728).
This fixes also the display in LyX (previously a literal ~ was displayed).
Using InsetMathSpace enables also the "Insert Formatting" menu entries.
No file format change is needed, since the LaTeX export is unchanged.
Note that there are still some bugs related to spaces in math:
#7746, #7747, #7749, #7842
