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 makes the defaults of Inset::inheritFont() and Inset::resetFontEdit()
compatible. There is no user visible change except for the Chunk inset which
does not produce invalid LaTeX after editing operations anymore.
This is the safe version for 2.1.0, for later there are still open questions:
- All insets with ResetsFont true should be audited: Is this really needed,
or do they show similar editing problems as the Chunk inset?
- Does inheritFont() need to be customizable in the layout file as well?
- Is resetFontEdit() != !inheritFont() needed at all?
I did not use change tracking for the docs, since I updated all existing
translations.
Fedora ships these chmod 644 and has never seen a problem. The advantage
to doing this is that it better controls what version of python we are
using to launch the script, and it will reveal if we're somehow somewhere
not controlling that properly.
(unless it's already there, in which case it should move to the end of the next paragraph).
Change the preference setting name (mac_like_word_movement to mac_like_cursor_movement)
to better reflect its function.
Patch and description from Bennett Helm
These should be used if any new style needs to be introduced in the stable
2.1 series: If the ForceLocal flag of the style is set, it will always be
written to the document header, so that even older 2.1 versions can read
and correctly output the document.
gnuhtml2latex does not handle encodings at all. Therefore the result is not
imported correctly by tex2lyx if the HTML file is encoded in anything else
than ascii or latin1 (the default of tex2lyx). The simple wrapper script
loads inputenc if needed. It may not be possible to compile the result with
LaTeX, (e.gif utf8 is used), but for running tex2lyx it will work just fine.
Previously, the format used for included pdf files was the same as for
document export via ps2pdf. This caused unwanted conversion routes, e.g.
export via odt->pdf instead of dvi->ps->pdf.
I renamed the format for included graphics and not for exported documents,
since otherwise the command line syntax for export would change. This would
require more adaptions for the users, since with the chosen solution the
custom converters are almost always changed correctly in prefs2prefs(),
so that only custom external templates need manual adjustement.
In particular, lilypond-book is just a python script. On windows,
we need to call the python interpreter, using the full path to
the script while being wary of spaces in the path.
causing a failure when running outside the user tree. This was my
fault: when I refactored this routine, I failed to note that this
variable was now undefined.
I'm afraid, but it's going to be. We skip all comment lines at
the start of the script, but what we want to convert here is in
those comment lines. My previous attempt to deal with this issue
produced an invalid file.
Unfortunately, this doesn't quite work the way one might like. It
is fine for manually converting one's own layouts to the new format,
but it doesn't work if you just start LyX, since the category info
is written at configuration time, not at run time, and chkconfig.ltx
does not run layout2layout.
Implement a more simple and elegant integration of the R package knitr. Now,
lyxknitr.R does not need to move or copy files at all.
This also fixes a bug: when /tmp was on a different file system (e.g.
encrypted home), lyxknitr.R failed to move files to /tmp because it relied on
R's 'file.rename' function, which in turn relied on the rename function in
<stdio.h>, which was failing with the EXDEV errno.
