Hello, I'm a semi-lapsed TeXmacs user. I love TeXmacs, but a majority of my mathematical work uses commutative diagrams, and the friction between TeXmacs and xypic is one of the big reasons why I head to LaTeX a lot.
The way that tikzcd/xypic does commutative diagrams is very natural; the items are put into a grid, and then arrows are drawn between them. It seems to me that this could be a great match for TeXmacs; all that would have to be done is add support for arrows to a subclass of the existing "table" layout. I know that commutative diagrams could be done with the figure drawing interface, however it's just not convenient enough to produce commutative diagrams in volume. Essentially my idea is to subclass table and add a list of arrows with source and target. Then during layout, after the layout of each of the table cells has been calculated, each arrow would go from the boundary of its source cell to the boundary of its target cell. As a newbie to the TeXmacs source, I would like to ask for some guidance about how to go about implementing this, however. Should it be done in C++, or could it be done in pure scheme? Are there "developer docs" somewhere that I should look at? Are there previous attempts along these lines, or similar pieces of code which I could look to for calculating the arrow source/targets? What is the minimal implementation of this that would get a commutative diagram on the screen, so that I can work off of that for developing the UI? Ideally, the UI would end up looking something like: https://tikzcd.yichuanshen.de/. -Owen _______________________________________________ Texmacs-dev mailing list Texmacs-dev@gnu.org https://lists.gnu.org/mailman/listinfo/texmacs-dev
