The math parser could not handle multicolumn grids. This is a problem because
there is no true ERT in math (everything is parsed).
Now multicolumn cells are parsed correctly. The display is also somewhat OK,
but apart from that any multicolumn related UI is missing. Since the file
format change is now done the UI can be added at any later point. The most
important part of bug 396 is now fixed: tex2lyx does not create invalid .lyx
files anymore for formulas containing \multicolumn.
I updated the tex2lyx test cases that produce correct output. tex2lyx does
still produce invalid output for the test cases which are not updated because
of the previous format change.
The computation of length on screen depend in particular of the computation of the size of an em. Many places of the code used to rely on the width of the M character, which is not really correct:
http://en.wikipedia.org/wiki/Em_%28typography%29
In digital typography, the best value to use is the point size of the font.
* Implement FontMetrics::em(), which returns the value in pixels of the EM unit.
Convert code to use it.
* Introduce Length::inPixel(MetricsBase const &), which takes the textwidth and em information from the MetricsBase object. Convert code to use it.
* Fix several places where Length::inPixel is used without a proper em value.
* add mathed_font_em() helper function. It should eventually be removed like some other functions in MathSupport.
* Add dummy implementation of FontMetrics to tex2lyx for linking purposes.
The problem was that the conversion to plain text (which is used as an
intermediate step) requires for some insets a valid buffer pointer, but
insets in the cut stack do not have one. Now we use the same temp buffer
business as for copying to the external clipboard.
each failure.
There are several places I was not sure what to do. These are marked
by comments beginning "LASSERT:" so they can be found easily. At the
moment, they are at:
Author.cpp:105: // LASSERT: What should we do here?
Author.cpp:121: // LASSERT: What should we do here?
Buffer.cpp:4525: // LASSERT: Is it safe to continue here, or should we just return?
Cursor.cpp:345: // LASSERT: Is it safe to continue here, or should we return?
Cursor.cpp:403: // LASSERT: Is it safe to continue here, or should we return?
Cursor.cpp:1143: // LASSERT: There have been several bugs around this code, that seem
CursorSlice.cpp:83: // LASSERT: This should only ever be called from an InsetMath.
CursorSlice.cpp:92: // LASSERT: This should only ever be called from an InsetMath.
LayoutFile.cpp:303: // LASSERT: Why would this fail?
Text.cpp:995: // LASSERT: Is it safe to continue here?
As discussed on the list. No automatic contents detection is done, the user
needs to use the special paste menu instead. I used the new TempFile class
for safe temporary file handling.
The documentation would go into section 2.2 of UserGuide.lyx, but I am not
allowed to edit that document.
Actually, the test case showed several problems:
- ERT insets did use layout "Standard", not "Plain Layout"
- The font scale was read correctly, but tex2lyx claimed that it did ignore
the option "scaled=0.95"
- If a third argument of the CJK environment was given, it caused the whole
environment to be put in ERT with a broken encoding. This is now fixed for
the bug test case by using the \font_cjk header variable, but the encoding
problem still exists for unsupported encodings. I'll file a separate bug
for that.
- The CJKutf8 package was not handled in the preamble parsing. Therefore the
chinese comment in the preamble was read with a wrong encoding, and guessing
the document language did not work.
The new file CJKutf8.tex was created by copying and modifying CJK.tex, but
unfortunately it is impossible to tell git to inherit the history of CJK.tex
for the new file (search the web for git svn copy if you want to know details).
* Avoid undo step when using backspace in macro mode
* Use recordUndoInset when entering macro mode (if one enters something like \hline, the outer inset itself will be modified)
* Use recordUndoInset when pasting in an INsetMathGrid (same reason as above)
If \hline is entered, do not create an unknown inset, but increase the number
of hlines of the current row if that is allowed. The same idea is applied to
copy-paste (not part of the bug report).
This is also a test for committing via git.
DispatchResult to store a flag that tells us whether we need a buffer
update or not.
So: If you find a missing one, go to an appropriate place in the
dispatch and call cur.forceBufferUpdate() or, if you don't have a cursor
but do have a DispatchResult, call dr.forceBufferUpdate().
There is one remaining call I could not move, in
TextMetrics::redoParagraph. But this looks like an emergency call when
the macro context has not been set. There are also a couple calls that
are connected with buffer creation that I commented out, since the same
call is done again almost immediately. But I'm not positive about those.
Now the nice thing would be to do the same for updateMacros().

This patch essentially reverts r30795 and also provides the correct fix
for #2969.

output routines. The idea is that in some cases people may not want to
use MathML, so we are going to try to give options.

- proper message passing for all tabular features
- properly define which feature needs an argument
* replace LFUN_TABULAR_FEATURE with LFUN_INSET_MODIFY
- The math tables are also affected. In the future a common base class
between math and text table will solve this inconsistency.
- There is a hack in GuiApplication in order to not rename the toolbar
icons. This will have to be cleaned up with a general icon naming for
LFUN_INSET_MODIFY... to be discussed.
* Tabular Dialog:
- big cleanup, lots and lots of bug fixing here
- migrated to InsetParamsWidget

This patch initializes the buffer_ member of a MathHull inset in most
(but not all) cases. The problems with buffer_ should be greatly
allievated now, but there still can be some corner case.

This reverts part of r10553. There, an extra '//' was added when the last line was empty. However, this really makes an extra line and that is visible when the lines have a line number. The bug #2067 that would have been fixed by this does not seem to 'exist' anymore.

6047: Lyx 1.6.3 unable to typeset the third chemical equation of the
file mhchem.lyx (package mhchem)
4043: mhchem support
5394: support for the mhchems's \ce command
The \ce and \cf insets are text mode environments that allow entering
spaces and mathmode commands. LyX leaves them alone and doesn't try to
be smart, i.e., the behaviour is exactly the same we had in the old days
with text-in-math mode environments, before the introduction of the
\ensuremath and \lyxmathsym macros. This means that in those environments
one has to know what he is doing, as LyX will not offer any protection.
The hack of enclosing \ce and \cf in a \text{} environment in order to
be able to enter spaces is no longer necessary.
