A simple Latex example

From time to time I check whether the situation with Latex in Maple has improved. Just one random example:

latex(2*x/(x-1));

2\,{\frac {x}{x-1}}

Is it really that hard to do a simple fraction?

Even double quotes in the math mode are still transcribed to a pair of single quotes, as if they were in the text mode,

latex("x");

``x''

Not even talking about spreadsheets and other total failures.

Is latex going to be deprecated (together with all other lower case commands)?

A better way to complain

You could consider actually showing what the 'correct' latex for these cases ought to be, in your humble opinion, and why. I am not defending Maple's sub-optimal choices here, but you'll find that this task quickly gets very difficult.

I agree

I agree.

In both examples, the latex code producing the same expression as Maple gives in the output in Classic, or 2D-input in Standard would be good - for using latex to convert a worksheet to pdf. I could write it if necessary (and I did that, I think, at least 3 or 4 times in earlier posts in various places during last 6 or 8 years, including few bug reports that I used to submit at that time) - but everybody else could do that, too (except Maple).

Edit: By the way - I am not complaining. I use Maple for entertaining purposes and every piece of it brings a lot of fun.

algolib LaTeX

I see that the algolib Library comes with a replacement LaTeX package. For these two examples, one works better, but the other not:

with(LaTeX):
latex(2*x/(x-1));

\frac{2 x}{x - 1}

latex("x");

Error, (in typetomath) x: invalid for math mode

Apparently, if "algolib" is in the 'libname' path, before the main library, the native 'latex' command cannot be used (even as ':-latex') because of a "missing" export in the algolib version of 'LaTeX'. Eg:

latex(a);

Error, (in latex/latex/symbol) CheckLineBreak is not a command in the LaTeX package

It seems that a number of 'latex' replacements have been developed independently.

Yes, algolib's latex is much-much better. I wonder why it was not included in Maple, together with equivalent and other algolib's parts significantly improving Maple math functionality.
