Could that be added as a configuration option?

A user recently asked how to find the set of indices corresponding to a given value of a two-dimensional Array.

There are several ways to handle this problem.  For  a single value, a simple scan through the Array suffices:

FindIndices1 := proc(A :: Array, val)
local i,j,irng,jrng;
    (irng,jrng) := rtable_dims(A);
    {seq(seq(`if`(A[i,j]=val, [i,j], NULL), i=irng), j=jrng)};
end proc:

With a multi-core machine, the ...

Jacques' post on the maple.vim project spurred this post.  Vim users cannot have all the fun.

About a year ago I wrote an Emacs front-end for the Maple debugger.  I've used it since---it is now my primary debugging tool for Maple code.  What it does is allow stepping through interpreted Maple code in an Emacs buffer.  That is, rather than being presented with a single line of...
