The compiler-generated copy-constructor and assigment operators would be wrong
for IconvProcessor::Impl, since cd would be copied, and iconv_close() could
thus be called twice on the same descriptor. The old code did work, but now
IconvProcessor::Impl cannot be copied by accident in the future.
The IconvProcessor assignment operator did not delete pimpl_ and used a
non-standard signature. If you want to know why the standard signature is
important, read "Effective C++" by Scott Meyers.
The statement
if (pos < from + lyxrc.completion_minlength)
triggers a signed vs. unsigned warning. I don't know why this happens, it
could be a MSVC bug, or related to LLP64 (windows) vs. LP64 (unix)
programming model, or the C++ standard might be ambigous in the section
defining the "usual arithmetic conversions". However, using a temporary
variable is safe and works on all compilers.
* fix handling of boundary situations in Row::Elements::x2pos;
* fix handling of boundary situations in TextMetrics::getColumnNearX;
* make sure to always use Font::isVisibleRightToLeft instead of Font::isRightToLeft;
* Improve debug messages.
The horizontal position of the inset was not taken in account.
The rounding is not always the same as with the old code, but this
is not really important.
Additional changes:
* improve debug output of rows
* remove Bidi& argument of the RowPainter constructor, since it is always
an empty Bifi that is passed. This means that the Bidi class is not
used at all any more in TextMetrics.cpp. The only remaining user is
RowPainter.
Break words longer than the screen width. The code is more complicated
than I would like, but I have no better idea right now.
Implement properly the notion of a row broken by a display inset. This is useful in different places.
Also fix a bug with last line of a paragraph spotted by Kornel.
Use proper font everywhere for end-of-par marker
Fix getColumnNearX for RTL text and for centered/right-justified paragraphs.
Let computeRowMetrics update the row width.
* convert cursorX to new scheme; old computation is still there for the sake of comparison.
* use Row to compute separator width in computeRowMetrics; again, the old code is retained for now.
* Get rid of rowWidth()
* Row now contains a vector of Elements
* replace Row::dump by a proper << operator
* the width is updated as elements are added
* breakRow is reimplmented to use this infrastructure
Collect properly all strings to compute string metrics
Some changes with respect to existing code
- end of paragraph font is now the one of the text
- words longer than a line are not broken anymore. I think this is not useful if we have horizontal scrollbar
Other than that, the code is still compatible with rowWidth and friends.
The magic library can detect the charset used by a file. While this
detection is not full proof, actually the library seems to be infallible
as regards the binary nature of a file. So, use libmagic for the detection
and fallback to the previous method if the library is not installed or
its database cannot be loaded.
On startup, the default locale is "C", meaning that all system
functions assume an ascii codeset. The environment's locale
settings should be selected by calling setlocale(LC_ALL,"").
This is done by Qt during the QCoreApplication initialization
but this inizialization is never performed for batch processing
and, as a result, LyX is not able to process files whose names
contain non-ascii characters. This is not an issue on Windows,
where the file names are always stored as UTF-16, so the call is
only performed for unix-like platforms (this also includes cygwin,
due to its own filenames management that allows using characters
which are forbidden to native programs).
FileName::tempName() created a new temp file name by using qt to create a
temporary file with a unique name, and then deleting that file and returning
the name. This was unsafe, since other processes or even other threads of the
running LyX could create files with the same name between deletion and then
using the temp name.
This is fixed by using the TempFile class instead. As a side effect, a few
cases where the temp files were not deleted after usage were fixed as well.
The only place that is still unsafe is createTmpDir().
The compiler generated copy constructor and assignment operator are wrong.
This could easily be fixed by implementing them manually, but a) they are
not needed, and b) the semantics would be unclear (should the copy point
to a new temp file or not?), so it is better to forbid them.
- The TempFile class guarantees to generate a file name, we are not limited to
100 tries of a predictable scheme anymore, which could break if LyX
frequently crashes.
- The temp file name generation has no race condition against another LyX
instance in the same directory anymore.
- Symlinks survive saving again (regression of 10364082c835).
Thanks to maciejr we know now what the remaining problem was with bug 7954:
My unicode symbol fallback works fine, the problem was that a font named
"Symbol" is available on OS X, but it does not use the font-specific encoding
we expect: Almost all glyphs are at their unicode code point.
Therefore the bug is fixed by re-enabling the unicode workaround and blocking
the Symbol font on OS X.
Maximizing the document settings window when on the modules pane,
the horizontal space is now given to the module names and so no
scrollbar is needed. Before, even when maximized, a scrollbar was
sometimes needed because the horizontal space was given to the
buttons in the middle, which did not provide an extra benefit.
The default sizeType was "Expanding" and is now changed to "Minimum"
for the horizontal spacer above the middle buttons.
Now the cursor in LyX jumps to the right spot instead of simply the
beginning of the paragraph. This is most useful for branch insets,
for example, which may contain long paragraphs.
If the reverse position corresponds to an inset, its paragraph id
does not follow the main text numbering. Typically, an inset has
only a few paragraph, so that we would jump near the beginning of
the document. In this way we at least jump at the beginning of the
inset.
If LyX does not know about a given file format, it may easily
happen that the format is recognized as "latex" and this causes
bug #9146. This patch limits the check for a latex format to
non-binary files. The strategy for deciding that a file has
binary content is the same as that adopted by the "less" program.
The problem is the use of cursor movement methods to update cursor.
Cursor::forwardPos() steps into insets, which is not always what we
want. The problem here is that there is a math inset just after the
accepted change, and that the cursor steps into it for some reason.
This code is a nightmare anyway.
Fixes: bug #9145
This regression was introduced by me at 8b66f9ce. I did not take
into account that a call to a python script containing $$s is embedded
within a separate python script. Thus, when commandPrep() is called it
only sees the call to the outer python script, and does not see the
$$s contained in that python script. It therefore did not substitute
for it. This fix simply calls commandPrep() directly before writing
the embedded command.
The Adobe EPS file format specification (TN-5002, currently available at
http://partners.adobe.com/public/developer/en/ps/5002.EPSF_Spec.pdf) specifies
a binary version of EPS files with integrated preview, sometimes also called
DOS EPS binary files. LyX 2.0 did recognize these files unreliably by
extension, but since f4eae12d they are misdetected as latex (bug #9146).
This change adds proper detection for these files using the officially
documented binary header.
