AsciiMath: Text below underbraces (ubrace) get shifted

[manuelfuenmayor]

Text below underbraces gets shifted to right.

Example:

M = ubrace(((0.5, 0, 0.5),(0, 0.5, 0.5),(0, 0, 1)))_("Adjustment to texture space") cdot ubrace(((2f//w, 0, 0, 0),(0, 2f//h, 0, 0),(0, 0, 1, 0)))_("Perspective projection") cdot ubrace(((r_x, r_y, r_z,0),(u_x, u_y, u_z, 0),(d_x, d_y, d_z, 0),(0, 0, 0, 1)))_("Camera orientation") cdot ubrace(((1, 0, 0, -P_x),(0, 1, 0, -P_y),(0, 0, 1, -P_z),(0, 0, 0, 1)))_("Camera location")

I can confirm that AsciiMath.JS has the same behavior. However I don't know if the asciimath gem does this or not.

ubrace(X, Y) is being rendered by the AsciiMath gem as <msub>X Y</msub>, instead of <munder>X Y</munder>.

That appears to be an oversight in AsciiMath gem: superscript and subscript with obrace and ubrace in AsciiMath are underscript nor subscript and overscript not subscript; just as with lim_blah.

Doing PR to asciimath gem

[opoudjis]

I have posted our kludge solution to riboseinc/asciimath, but hopefully the PR will be integrated into asciimath proper.

[opoudjis]

I will also implement the LaTeX version of this, Pepijn is too busy.

[opoudjis]

Implemented, waiting now on Pepijn.
