Addressing #10481.
This patch adds the new 'needauth' option for converters launching
external programs that are capable of running arbitrary code on behalf
of the user. These converters won't be run unless the user gives explicit
authorization, which is asked on-demand when the converter is about to
be run (question is not asked if the file is cached and calling the
converter is not needed).
The user prompt has a 3rd button so that he/she's not prompted again
for (any converter over) the same document (identified through
buffer->absFileName()).
Two preference options are added:
lyxrc.use_converter_needauth_forbidden disables any converter with
the 'needauth' option, which is meant to force user to an explicit
action via the preferences pane, before being able to use advanced
converters that can potentially bring security threats;
lyxrc.use_converter_needauth enables prompting the user for 'needauth'
converters, or bypasses the check if not enabled, falling back to the
previous behavior.
So, the first option is for maximum security, the second is for
maximum usability.
Based on Daniel Groger's work of five years ago, with minor changes
http://www.mail-archive.com/lyx-devel%40lists.lyx.org/msg169820.html
This extends the support for Xfig LaTeX + PDF to a more modern and
actively developed vector graphics editor. Embedded Objects manual
updated, also to include a workaround for an Inkscape 0.91 bug.
We do already have docx, but xlsx was missing. This is a separate format
because of the MIME type. nd because some users might need converters which
can only handle one format. Now the spreadsheet template does not hide the
fact anymore that it can deal with xlsx files as well.
After the fix at fe06ef0e, several converter chains to DVI
(dviluatex) were broken because they had previously gone through an
incorrect link in the chain.
This commit adds converters for the above formats to dviluatex and
fixes the following ctests:
export/examples/Literate_dvi3_texF
export/examples/Literate_dvi3_systemF
export/examples/knitr_dvi3_texF
export/examples/knitr_dvi3_systemF
export/examples/lilypond_dvi3_texF
export/examples/lilypond_dvi3_systemF
export/examples/noweb2lyx_dvi3_texF
export/examples/noweb2lyx_dvi3_systemF
export/examples/sweave_dvi3_texF
export/examples/sweave_dvi3_systemF
export/templates/RJournal_dvi3_texF
Although this a problem that only manifests itself on windows the change is general
and it works anywhere.
The major change is to change the file redirection > to -o the specifies the output file.
At the same time it makes the call to lyx2lyx less cryptic, e.g. to revert to the 1.3
format we have:
\converter lyx lyx13x "python -tt $$s/lyx2lyx/lyx2lyx -t 221 $$i > $$o" ""
now instead of
python -tt $$s/lyx2lyx/lyx2lyx -t 221 $$i > $$o
we use a call where the version to revert is explicit
python -tt $$s/lyx2lyx/lyx2lyx -V 1.3 -o $$o $$i
or we could write a longer, but more understandable form:
python -tt $$s/lyx2lyx/lyx2lyx --final_version 1.3 --output $$o $$i
FWIW I shuffled the order of the arguments just for the sake of readability,
to let $$i be the last argument.
The external templates requested conversion to these formats, but there was no
converter defined, so plain text export did fail, and there are no obvious ways
to create plain text representations for the files used by these templates.
Now we output the file name as for other templates and also the graphics inset.
This fixes bug #7135.
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.
LyX did not distinguish compressed and uncompressed svg files previously.
Therefore XHTML export of vector graphics did use svgz images directly, which
is not supported by browsers. If svg and svgz are treated as two formats then
all works fine. This is also consistent with the loadable image formats
reported by qt: It reports both svg and svgz.
The gunzip dependency in converters is not new (it is already used internally),
but the gzip dependency is new, so it might not be available on windows.
This is not important at the moment, since we do not yet need to convert svg
to svgz, I only added the converter for completeness.
We ensure that configure.py is called by python2, regardless whether 'python'
is python 2 or 3. Therefore we can simply call TeXFiles.py with the currently
running interpreter. This fixes configuration on systems where 'python' is
python 3.
Otherwise it could easily happen that the order is changed, since rsvg_convert
seems to be more picky about invalid files (see http://www.lyx.org/trac/ticket/9891)
* Omit commented-out lines
* Properly escape backslash
* Do not allow non-space chars after delaration
* Allow blanks before # comment character
Fixes: #9746
The path argument of checkProg* was added to the PATH list in a nested
loop such that the list doubles in size each time the loop is executed,
thus also slowing down detection of missing programs.
When closing a document with the cursor near an icon info inset, LyX
may crash on loading again the same document. This is most probably due
to the fact that compressed svg icons are first uncompressed to a
temporary file before being used. The temporary file is then deleted
but something still expects to find it in place. The exact circumstances
that lead to the crash are unknown, and maybe there is also a race entering
the picture here. However, a document that always leads to a crash can be
found attached here: http://article.gmane.org/gmane.editors.lyx.devel/154566
This commit does not fix the cause of the crash but rather avoids it.
As a bonus, the svg icons used by LyX are not uncompressed anymore before
being used, speeding up startup time. This is not a problem, because Qt
can deal with compressed svg images.
As discussed on the list, but I did not need to create two new pdf formats
since any given document either uses TeX fonts or not. For the same reason
I also added an additional converter to PDF (cropped).
