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.
This patch improves the cmake bundling process:
- reworked bundle handling for OS X: only when installing resources are copied, otherwise
only the smallest bundle is built
- on OS X, the utility programs (tex2lyx) are now installed in the right location
- it removes some unneeded BUNDLE DESTINATION
- it provides a basic support for QT plugins inclusion
- it properly builds a disk image on OS X (only the background image is missing)
- it fixes the library paths for all executables (not only LyX)
- Use the COPYING file for cmake install license
These started failing after we implemented tests for formats
that are in the complement set to the default format (7ecbb068).
It might be worth it in the future to take a look at each individually
and see whether they are supposed to fail or if there is something LyX
can do to add support for exporting them.
As discussed with Vincent I added 3 new features:
* LyX can now also be installed over an existing installation of the same LyX version if the users really wants this.
(A message box appears recommending not to do so for test releases and when there are problems with an existing installation of the same release.)
* LyX can now also be installed if the uninstaller executable of a former LyX was accidentally deleted.
(That this case was not handled was more a bug. Thanks Vicent for the pointer.)
* If a user set MiKTeX's automatic package installation to "No" the installer will.
(As discussed with Vincent, if a user has disabled this MiKTeX feature he most probably know the consequences. So respect his decision.)
respect that and not re-enable it.
I would be happy if anybody can spend a translation of the changed installer message.
- known problem: if LyX 2.0.x is installed and you install 2.1rc1, the .lyx file associations will not be updated but if LyX 2.1 is installed on a new PC the file associations work (work is in progress)
Define new policy of what export formats to check.
Depending on default_output_format
default or unset xhtml, dvi*, pdf*
xhtml xhtml
any of pfd variants xhtml, pdf*
any of dvi variants xhtml, dvi*
each other (like eps3) as specified
- it turned out that the hack to install a stripped-down Perl directly to MiKTEX is not only error-prone, requires admin permission but that it is also not safe because MiKTeX changes the folder structure from time to time. With the new solution Perl is installed directly for LyX like we do for ImageMagick, Python etc.
- for pdfcrop support there is a bug in pdfcriop that the requirement is hardcoded to Ghostscript 32bit - I contacted the pdfcrop author to fix this
This test was broken after wrap-around search was implemented. From
what I understand, the point of the test is that search should _not_
match in this case because "ignore format" is checked by default.
Thus, a new way of testing that there was no match is to check whether
the wrap around message shows up, because the cursor is initially at
the beginning so that would mean that the entire buffer was checked.
I confirmed that the test now works by checking that it passes and
checking that it fails if "ignore format" is unchecked. Although this
test is still fragile, it is fragile in a conservative way (i.e. it
will give false failures rather than false passes). It will fail if
the Italian translation changes, if "ignore format" is unchecked by
default, or if the wrap-around mechanism changes (e.g. does not ask if
the cursor started at the beginning of the buffer).
