These were a bit difficult to answer, cause i dont know exactly what youre after - precise examples such as given in question 1 would be helpful. I could be way off base on what you were asking about in your questions.

In general i think you might want to look into image based programming if you havent already (e.g. smalltalk systems, lisp machines, etc.) as many of these provide language server esq connections to their editor. Of note is interlisp-d with its structural editor, which if i remember right edits the source code data structures in memory.

Regarding Q1: this workflow has been implemented in various languages for a long time. The one i am most familiar with is the swank/slynk server for CL. If i remember right it opens up its own thread to process everything, and communicates on a specific port.

Regarding Q2: perhaps im misunderstanding or just forcing my own perceptions onto the question, but this seems to be more an issue of session management within the LSP client; assuming communication over a specific port, its more about the client figuring out which commands to send to which port.

Regarding Q3: im probably misunderstanding this one, because it seems like a duplicate of question 2 with some extra requirements

Regarding Q4: this can also be done. For loading from markup see literate programming (theres a CL system for loading systems from org files called literate-lisp). For loading from the internet and databases, im unsure what you mean; whether source code or byte code or machine code or what have you its all just ordered information, which can be grabbed from its storage location with the right tools (web client, db bindings, etc).

Hopefully all that was helpful :)

Until thats done, i think that could be done with an automoderator. E.g. iff a post title begins with [ONLYLOCAL] then trawl the comments every n minutes and remove all comments from nonlocal users. Maybe it would fall apart at scale? But im not sure. It would certainly be more performant as part of the software itself, but i do think its possible with an automod.

I dont think they defederated; i still see hexbear in the linked instances section. You can see it at the bottom of the page in the browser if you click the ‘instances’ link.

I feel like this is something where you, the admins, take priority. While i havent noticed much hate or spam from kbin.social (aside from random), if it is making enough impact that the admins dont have the resources (either time wise, emotion wise, or what have you) to do other admin things then i support you in defederating. Of course, i prefer to stay federated, but because you and the other admins and mods are doing the heavy lifting here i think your thoughts and feelings on this matter take priority.

Well, i can recommend infinity train. Elevator pitch: theres a train with passengers. Each passenger must work through their trauma to get off the train. Its not explicitly queer tho.

Ive also heard good things about star vs the forces of evil, but havent watched it myself, and dont know much about it.

I think goblincore is fairly different from the traditionall antisemitic goblins.
