A silly LaTeX error took me a few minutes too many to solve: I defined
[sourcecode gutter=”false”]
\renewcommand\theta{\boldsymbol{\theta}}
[/sourcecode]
which got me the error message
[sourcecode gutter=”false”]
TeX capacity exceeded ,
sorry [ grouping levels =255].
[/sourcecode]
that I understood as a recursive definition. So I instead pre-defined the new θ as
[sourcecode gutter=”false”]
\newcommand\btheta{\boldsymbol{\theta}}
\renewcommand\theta\btheta
[/sourcecode]
which did not work either… After google-ing the issue, I found this on-line LaTeX Wikibook that provided me with the solution:
[sourcecode gutter=”false”]
\let\btheta{\boldsymbol{\theta}}
\renewcommand\theta\btheta
[/sourcecode]
which worked. Of course, a global change of \theta into \btheta would have been much much faster to execute….
