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.

|
* MathEnsurer - utility class for ensuring math mode
|
|
*
|
|
* A local variable of this type can be used to either ensure math mode
|
|
* or delay the writing of a pending brace when outputting LaTeX.
|
|
*
|
|
* Example 1:
|
|
*
|
|
* MathEnsurer ensurer(os);
|
|
*
|
|
* If not already in math mode, inserts an \ensuremath command followed
|
|
* by an open brace. This brace will be automatically closed when exiting
|
|
* math mode. Math mode is automatically exited when writing something
|
|
* that doesn't explicitly require math mode.
|
|
*
|
|
* Example 2:
|
|
*
|
|
* MathEnsurer ensurer(os, false);
|
|
*
|
|
* Simply suspend writing a closing brace until the end of ensurer's scope.
|
|
*
|
|
* Example 3:
|
|
*
|
|
* MathEnsurer ensurer(os, needs_math_mode, true);
|
|
*
|
|
* The third parameter is set to true only for a user defined macro, which
|
|
* needs special handling. When it is a MathMacro, the needs_math_mode
|
|
* parameter is true and the behavior is as in Example 1. When the
|
|
* needs_math_mode parameter is false (not a MathMacro) and the macro
|
|
* was entered in a text box and we are in math mode, the mode is reset
|
|
* to text. This is because the macro was probably designed for text mode
|
|
* (given that it was entered in text mode and we have no way to tell the
|
|
* contrary).

* ModeSpecifier - utility class for specifying a given mode (math or text)
|
|
*
|
|
* A local variable of this type can be used to specify that a command or
|
|
* environment works in a given mode. For example, \mbox works in text
|
|
* mode, but \boxed works in math mode. Note that no mode changing commands
|
|
* are needed, but we have to track the current mode, hence this class.
|
|
* This is only used when exporting to latex and helps determining whether
|
|
* the mode needs being temporarily switched when a command would not work
|
|
* in the current mode. As there are cases where this switching is to be
|
|
* avoided, the optional third parameter can be used to lock the mode.
|
|
*
|
|
* Example 1:
|
|
*
|
|
* ModeSpecifier specifier(os, TEXT_MODE);
|
|
*
|
|
* Sets the current mode to text mode and allows mode switching.
|
|
*
|
|
* Example 2:
|
|
*
|
|
* ModeSpecifier specifier(os, TEXT_MODE, true);
|
|
*
|
|
* Sets the current mode to text mode and disallows mode switching.
|
|
*
|
|
* At the end of specifier's scope the mode is reset to its previous value.
