leo-editor VS lsp-mode

What are your experiences with literate programming for handover of code?

I am thinking of tools like noweb (https://en.wikipedia.org/wiki/Noweb), LEO (http://leoeditor.com/) org-mode (http://cachestocaches.com/2018/6/org-literate-programming/), scribble/lp2 (https://docs.racket-lang.org/scribble/lp.html#%28part._scribble_lp2_.Language%29),

My experience so far is that it can be a fantastic tool for documenting and handing over complex algorithms to successor developers. I use extensively use ersonal wikis (sometimes MoinMoin, sometimes Zim Wiki, in the last time often a combination of github with reStructuredText) for work. That might also be sufficient when handing over boring code.

I know what folding is, that's just not what I want. I want to completely hide everything that is not related to the current function. For a while, I used http://leoeditor.com/ where I could have every function/method as a node in a tree, with the node body containing just that. Looking for a way to achieve the same in vim if possible.

The lack of good node/graph based APIs for Org Mode is my beef as well. When you compare it with the APIs of the Leo Editor[1], Org pales in comparison. Manipulation that is trivial in the Leo Editor can be quite a pain in Org mode.

> What outliners do you know which allow end-users to feed their data into formulas for processing it without using general-purpose programming languages?

Bit of a pointless constraint, the talk is about outliners, not no-code-datamangment. Which tool today does this even offer on a useful level?

But you can look at leo editor (https://leoeditor.com), which is active for 20+ years, fully scriptable and extendable. Though, it's a hot piece of garbage for laymen. It's offers a bunch of features and plugins even for non-coders, but I'm not sure it would satisfy you for this area, if you can't code.

But I'm not sure if there ever is a tool which will satisfy everyone with just a no-code-approach.

Hmm maybe you mean:

- Programming based on fragments, not documents (e.g. LEO https://leoeditor.com/)

- Live programming (e.g. smalltalk environments)

- ... where certain actions are not available, e.g. a PL geared towards speech recognition may not support "hover"

There's also https://leoeditor.com/ where you can have a tree of nodes and execute any of them.

I had this problem until I found an editor that had outlining as it's core design paradigm. Now, with the outline always visible, it's _really_ easy to navigate any length file.

Unfortunately, at one point I got so used to navigating with the outline that I ended up making a 1500 line function in C (I was an even worse C programmer then than I am now). Because of the outline, I could read and follow it easily, but anyone with a different editor was royally screwed :-(

If you're interested, the editor is LEO (http://leoeditor.com/) it's been mentioned on HN a few times

I also tried to the solutions suggested  and , but nothing worked. I moved the (setq lsp-keymap-...) line outside (and before) use-package. I also used :config (define-key lsp-load-map...) in my use-package block. But none of them worked.

Not sure how much this might help, but lsp-mode has lsp-yaml-select-buffer-schema and lsp-yaml-set-buffer-schema commands to pick schema from a list or set from a URI. Checking the source of them might give some hints about how the same could be implemented in eglot?

Beyond that you might as well embrace the suck and install autex with a language server: https://emacs-lsp.github.io/lsp-mode/

Smart completion these days is done primarily through LSP. eglot is fairly minimal but built-in as of 29, also available via GNU Elpa. lsp-mode is another option with more integrations and a bit more fleshed out.

lsp-mode: https://github.com/emacs-lsp/lsp-mode/issues/2080

Are you running emacs-29? It has numerous speed-ups compared to emacs-28 and older versions, many of them coded by Mattias Engdegård, e.g. commit def6fa4246. I have a fresh build of emacs-29 running on Linux and a new mac with an M1 CPU, and it's stupid fast. I don't use the native-comp feature. I rarely notice any hesitation or slowness. I don't use Elpy. I do use lsp mode.

Since you are doing code development, the first things to go for would be setting up your emacs packaging (installing use-package and melpa (use-package's documentation covers this) so you have more packages to choose from (do be careful to not just pick things willy nilly but research them a bit first)) and then setting up lsp-mode. lsp-mode lets you use LSP servers for the specific programming languages you work with in a somewhat unified fashion. You then need to install and setup the LSP servers for the languages you use, and possibly install language specific Emacs packages as support (note, Emacs has builtin functionality for many).

And first of all, I'm trying to understand, how is it connected to https://github.com/emacs-lsp/lsp-mode? I'm sure, that existed lsp implementations already parse source code. Why TreeSitter?
