@viz Well, I seem to have figured things out. I brought together the JuliaCtags #JuliaLang package to generate a `ctags` file suitable for use by `exuberant-ctags` on Linux (at least). I used this to generate tags for my various projects both individually and all together as well as tags for the full Julia base module. This was then followed by the configuration of `tags-table-list` [*] in #Emacs to work with multiple tags files.

The results is that the various Emacs #xref commands work very well for navigating in the code: jump to definitions, find all references, go back and forth, etc.

[*] the use of a table of tags files is quite important when working with multiple inter-linked packages. I hadn't known about this variable before as I somehow missed the relevant paragraph in the documentation the various times I'd checked previously. :-(

Hello #fediverse #introduction

I'm Michael, professor in the institutes of #mathematics and #materials science and head of the @MatMat group at #EPFL.

I work on the #atomistic simulations of materials, mainly density-functional theory (DFT) methods, understanding #simulation errors and #uncertainties in predicted materials properties.

I use techniques from
#physics #computerscience #machinelearning and
develop related #julialang packages such as the density-functional toolkit (#dftk).

I spent yesterday trying to find the best way to plot this very detailed image. Due to its many overlapping lines, regular paper didn't hold up to repeated passes unless I used a ballpoint, which shed ink in a way that I found distracting.

In the end, the best result came from a 0.1mm Rotring Isograph with Black DeAtramentis Document ink on Yupo paper. Amazing detail and tonal gradation. 🔥

Continued thread

I developed this pkg to solve classical Operations Research problems using the Julia language. It handles Simplex, Transportation, Assignment, Shortest Path, Minimum Spanning Tree, Maximum Flow, CPM and PERT, location selection, Scheduling problems etc..

I recommend Julia to my colleagues teaching Operations Research and related courses. With only the JuMP and HiGHS packages, you can introduce many topics from an operations research textbook. For nonlinear optimization, simply changing the solver is sufficient.
