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.
The \jobname macro is redefined for the preview snippets such that
it contains the name of the document without extension. This is
harmless because the moment it is redefined, TeX has already chosen
the name of the output and log files. On the other hand, any use
of \jobname in preview snippets is now consistent with what one
obtains after exporting and compiling by hand.
This was a regression of 0c093a6264. The crash was found by the tex2lyx
test case test-insets.tex: Running lyx -f main -e pdflatex test-insets.lyx.lyx
did crash. This is not a real fix, but will do for now since previews are not
needed in command line mode (I wonder why they are generated at all?) In the
long term, we need theApp() to return a console application in commandline
mode to eliminate the existing sifferences between export from GUI and
commandline.
If latex fails to generate any output, the forked process was not removed.
Now, if a snippet was changed a new one was started but, if also the zoom was
changed, things went awry because the 2 concurrent processes were asked to
process again the same snippet. Previously this would have simply caused a
waste of resources because the changed snippet would have not been regenerated.
Also reset the guard due to the early exit.
If the zoom factor is changed right while the previews are being
regenerated, the refreshPreviews() method is a no-op. So, reschedule
the refresh until everything is ready.
Relying on the fact that the timer is not active anymore does not
guarantee that the previews at the correct zoom are ready because
the regeneration process may take several seconds and during this
time the zoom factor may be changed again. So, we need an additional
guard for assuring that everything has settled down.
Until now the regeneration process was starting as soon as the zoom scale
factor was changed. This was causing some glitches, especially if the zoom
was changed by the mouse wheel, as on each change the process was started
again and again making zoom changes painful and causing races such that
one could end up with the text at some zoom factor and the previews at
another one. After this commit, the regeneration is started only after
the zoom factor has been stable for about 1 second. In this way, one can
use the mouse wheel for changing back and forth the zoom factor at own's
heart desire without any slow down due to the regeneration process running
in the background. For those using previews with numbered math equations,
a nice possibility for getting the equations correctly numbered in sequence
(after removing or adding an equation) is using the shortcuts Alt+ and Alt-
in rapid sequence (less than a second between the keystrokes). Previously,
this would have triggered twice the regeneration, but now only once.
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
Avoid that \newcommand[x] definitions of math macros are pushed multiple
times to the preview loader.
Redefinitions (via \renewcommand[x]) are properly handled.
The preview snippets are cached in a seemingly random order, such
that, when regenerating them on zoom, the math previews would be
numbered accordingly. Hence, we have to go through the insets to
get the correct order. This is a bit slower but unavoidable.
Sometimes, even compilable documents could not display preview
snippets. Previously the preview was computed only with help
of latex or xelatex.
This also fixes#9371
Add display_pixel_ratio to buffer params to use it for displays with high resolution.
It holds the highest ratio between physical pixels and device-independent pixels of the LyX application.
Preview snippets will be generated using this value to get high resolution preview.
Now the replacement is done in startScript(). In addition to making
the code cleaner and more consistent, this commit fixes a bug where
"$$s" was not replaced when "latex=" was specified in the extra flags
of a converter.
Note that the temporary fix at 731b8610 is reverted with this commit.
for possible thread conflicts, of the sort Georg resolved at
6a30211f. I have made static variables const where possible,
and marked cases that looked potentially problematic with the
comment:
// FIXME THREAD
Many of these definitely are vulnerable to concurrent access, such
as the static variables declared at the start of output_latex.cpp.
Suppose, e.g., we were outputting latex and also displaying the
source of a different document.
I'd appreciate it if others could grep for "FIXME THREAD" and see
if some of these are harmless, or what.
While exporting from the command-line, theApp() doesn't exist.
The colors foreground and background are only needed when
previewing, so ignore this during buffer export.
This replaces the fix in 4285b0b3 (Tommaso Cucinotta, 10-12-2012).
In this case, we do not need to pull in Qt dependencies.
This restores \input@path handling, which turns out to be necessary, as
the TEXINPUTS mechanism is not used with relative paths. It turns out
that both methods must be used, because \input@path does not work in all
cases (most notably with tikz).

Let's have this in trunk for testing. The real difference maker
when it comes to color is whether we use dvipng or ghostscript.
For dvipng:
- The color info is passed as command-line arguments.
- The tightpage option is not necessary, and since it adds
ps specials to the output, we shouldn't use it.
For ghostscript:
- The color info needs to be in the latex file.
- The foreground color is set for each preview inset.
- The background color is set by \pagecolor in the preamble,
which is understood by pdflatex, but ignored in dvips mode.
Thus dvips is handled with a ps special.
- The tightpage option is necessary to crop the images.

- Japanese is now handled by passing the option --latex=platex
to the standard lyxpreview script. This is done in PreviewLoader.
- Remove obsoleted file lyxpreview-platex2bitmap.py and the
corresponding lines in the configure script.

- Handle the preprocessing in the main lyxpreview script with the
command-line arguments --lilypond and --lilypond-book=exe.
- Remove the obsoleted file lyxpreview-lytex2bitmap.py and the
corresponding lines in configure.py.
Fix for the japanese preview still to come.

Add command-line arguments in a standard unix fashion, using getopt.
Usage: ./lyxpreview2bitmap.py <options> <input file>
Options:
-h, --help: Show this help screen and exit
--dpi=<res>: Resolution per inch (default: 128)
--png, --ppm: Select the output format (default: png)
--fg=<color>: Foreground color (default: black, ie '000000')
--bg=<color>: Background color (default: white, ie 'ffffff')
--latex=<exe>: Specify the executable for latex (default: latex)
The colors are hexadecimal strings, eg 'faf0e6'.
The changes to PreviewLoader.cpp break the preview of lilypond-book
and japanese files, but they will be handled in the next commits.
