Increase tex2lyx output format to 298.
298: All math macros are exported with \\global to LaTeX now, so a \\global
in front of a math macro has to be recognized. Since the math macros do
no longer use the same syntax in .lyx and .tex (which is a mistake IMHO)
an exact match is no longer possible except for \global\long\def.
Bugfix this time: \\providecommand was errornously recognized as math macro

\section{Macros}
|

|

LyX supports several kinds of macros:
|
||||
def \def\macroa#1{a #1 a}
|
||||
global def \global\def\macrob#1{b #1 b}
|
||||
long def \long\def\macroc#1{c #1 c}
|
||||
global long def \global\long\def\macrod#1{d #1 d}
|
||||
providecommand \providecommand{\macroe}[1]{e #1 e}
|
||||
newcommand \newcommand{\macrof}[1]{f #1 f}
|
||||
renewcommand \renewcommand{\macrof}[1]{g #1 g}
|
||||
|
||||
Now use them all:
|
||||
\macroa{x} \macrob{x} \macroc{x} \macrod{x} \macroe{x} \macrof{x}
