The math parser aborts with an error message on \begin{align} and
\begin{align*} if this is not the hull inset. This is now fixed, however
this is not complete support for these two environments (the GUI does not
respect the numbering). It is only the minimal fix that ensures that no data
loss occurs for documents imported by tex2lyx.
This comes from trying to run tex2lyx on the AMS math test document
testmath.tex. Both \(...\) and \begin{math}...\end{math} are defined as
inline math formulas in standard LaTeX. tex2lyx recognizes this, but the
math parser in LyX did not handle "\begin_inset Formula \(" and
"\begin_inset Formula \begin{math}" correctly.
The fix is simple and safe: If we are in undecided mode (this is only true
for the first token of a math inset), create a hull inset of the respective
kind. Otherwise, handle the commands as before.
This avoids a message "Deco was not found. Programming error?" on stderr.
The added decorations are defined by amsmath, and equivalent to \vert (single
vertical bar) and \Vert (double vertical bar), respectively. They are used to
distinguish the single and paired versions (for use with \left and \right).
These symbols should cause amsmath to be loaded, but this would be too
dangerous to implement now.
Now interactive insertion of \smash[t] and \smash[b] is possible again.
\smash with optional argument behaves now exactly as in LyX 2.0.x, and without
optional argument it is supported by InsetMathPhantom.
When adding native support for \smash in 18779013 I overlooked that amsmath
redefines \smash to take an optional argument t or b. These optional
arguments are not parsed correctly anymore (bug 8967). This change fixes
the regression, so that \smash with optional argument appears in red, as it
was before th introduction of the native smash inset.
In the future, we should have native support for \smash[t] and \smash[b]
as well, but this would be a file format change (automatic amsmath loading),
and it is too late for 2.1.0.
When we export the file to latex, we use the redefinition_ variable to check whether we should output newcommand or renewcommand. This variable was set by the MathMacroTemplate::metrics() function, and this caused problem when the export is running in a different thread as the GUI.
In general, the metrics() functions should not change the Buffer; we have updateBuffer/updateMacros for that purpose.
Not all accessors did update the data previously. Therefore it could happen
that document export from the command line would output \newcommand, and from
GUI it would output \renewcommand for the same macro, simply because in the
GUI case the data was updated as a side effect of the GUI thread reading some
other member.
I also removed the mutable flag for requires_, since this member is always
set on construction and does not need any lazy update.
This is mostly unused private class members.
There are also a few unused functions that got #if'ed out. I never know in this case whether the code should be nuked.
False positive rate of hints is quite high. Although the includes can be
technically removed (due to other includes) they logically belong to the
header.

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

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.
worth doing, as we were creating too much output for tooltips anyway.
But we need to ignore BibTeX insets altogether, as the collection of
the references, etc, is too slow.
so we can write a limited amount when using this for TOC and
tooltip output.
This should solve the problem with slowness that Kornel noticed,
which was caused by our trying to write an entire plaintext
bibliography every time we updated the TOC. We did that because
he had a bibliography inside a branch, and we use plaintext for
creating the tooltip that goes with the branch list.
Other related bugs were fixed along the way. E.g., it turns out
that, if someone had an InsetInclude inside a branch, then we would
have been writing a *plaintext file* for that inset every time we
updated the TOC. I wonder if some of the other reports of slowness
we have received might be due to this kind of issue?
Somehow I overlooked that \sideset also supports nonscript arguments for
left and right. This is now fixed, although I do not like the toolbar names.
If somebody knows something better, please improve.
The toolbar image is the one Uwe attached to the bug report. Note that
\sideset works only for operators like \sum in the nucleus. LyX allows
any content, so you might get a LaTeX error. I don't know how to prevent
wrong content in the nucleus.
Some macros defined by wasysym.sty work only in text mode: They either
produce an error in math mode, or wrong output. These symbols are now marked
as text symbols, so that no \ensuremath is created for LaTeX export if they
appear inside \text{}, and the correct images are created.
