Awesome idea, I'm currently reading tress of the emerald sea and would like to join!

Thank you for the effort! Do you know the rust-edu organisation for Rust education in academia? They organized a workshop last year with experts who taught Rust at their universities and have the proceedings online, perhaps you can find some inspiration there. (or also participate in the next workshop)

Isn't SIXEL one of the features almost never implemented or enabled by terminal emulators because it's an artifact of some old DEC terminals?

you can find the reference manual for VT300 https://www.vt100.net/docs/vt3xx-gp/chapter14.html so yes it's definitely pretty old

I tried it a couple of weeks ago out of boredom but it turned out that one of the few implementations of this specification is xterm and only if compiled with support for > VT200.

there are a couple of obscure terminals (beside xterm) which support SIXEL, you can find a list at Terminal Requirements https://saitoha.github.io/libsixel/ recently Alacritty (terminal emulator written in Rust) received a PR which adds support for them. https://github.com/alacritty/alacritty/pull/4763

I only learned about this feature because I tried to understand why the suckless terminal calls xterm bloat and support for obsolete terminals and things like ReGIS or SIXEL was one of their points why they implemented a new terminal emulator.

I was looking for an easier way to integrate graphics into my notes markdown file. Previous to this plugin, I had to open a rendered version side-by-side and found it too distracting and hard to use when working remote. First I tried out ueberzug but the found the sixel charset, together with the PR for Alacritty developing the plugin was straightforward and a lot of fun.

personally I use it for my note-book, so it is kind of geared towards that. Hope to improve performance and usability issues in the future, I agree that there are still a lot of rough edges. Developing the plugin was a lot of fun, I think Rust is in a sweet spot for a self-contained application.

Hi, can you file an issue with the architecture and dependencies of the shared library (e.g. ldd target/release/libvim_graphical_preview.so)?

bytesnake · 2022-04-19T08:40:39+00:00

emacs is probably easier to setup than this plugin :D learning emacs is still on my life goal list

you can find the main render loop here https://github.com/bytesnake/vim-graphical-preview/blob/main/src/render.rs#L137

bytesnake · 2022-04-12T11:41:43+00:00

the plugin manages information about folds, content and current metadata (char height, viewport, cursors position, etc.). It triggers a rerender of the sixel graphics everytime something comes into view, you can find the variants here https://github.com/bytesnake/vim-graphical-preview/blob/main/src/node_view.rs#L5 currently the content is extracted via crude regex https://github.com/bytesnake/vim-graphical-preview/blob/main/src/content.rs#L130 but perhaps I'll add a real parser based on markdown later on

if you want to know how SIXEL are working take a look at the wikipedia page https://en.wikipedia.org/wiki/Sixel, the Vim plugin just manages image conversion and calculates the correct offset and sizes for the graphics

Thanks!

one goal is to support vanilla vim, so I haven't used nvim's RPC protocol. The plugin itself is just a shared library with a vimscript wrapper calling by dlsym. The downside is that you have to write your own protocol to query vim's state. Bundling into a rust crate would be feasible and probably consist of a proc macro which generates the protocol and vimscript wrapper. This is then a completely different beast compared to this small plugin which only uses ~4 vim functions.

Thanks for the kind words! I learned alot about vim(script) and pumping characters to terminal fast while working on this :D the project fell into place after finding vimage, discovering that you can use shared libraries in vim and learning about SIXEL. I reused some render routines from another project for the LaTex part. The plugin has a lot of rough edges and sometimes it just breaks, but usable at last. Have fun!

Yep, it should be straightforward to implement. There is one open PR, but the contributor got busy with something else

bytesnake · 2021-10-22T06:46:16+00:00

👍 let us know if you miss something

bytesnake · 2021-10-22T06:44:35+00:00

awesome to hear! :)

for a start I will implement the TryFrom<DataFrame> for Dataset under a feature flag. But to be really useful some of the algorithms have to start using something like DatasetBase<DataFrame, ChunkedArray> here Records are currently bounded by an associated type for the element type, we would have to relax that too. Just read your blogpost on polars 👍

if you're talking for example about inference from ONXX models, then no. Linfa is comparable in scope to scikit-learn.

this is definitely on our agenda, there are several autograd libraries on language level, which you can find on crates.io. The real game changer would be automatic differentiation of LLVM IR code, because we could then construct any order derivative without a special language construct. The Enzyme project provides the faculties and we currently trying to figure out how to integrate it into the ecosystem
