The Future of SCIP

The git repo is here: https://github.com/scip-code/scip

Looks like it's defined using protocol buffers, with "rich Go and Rust bindings" and links to implementations for many other languages.

I can’t speak for the Go bindings, but using the Rust crate has been pretty clean. Haven’t really felt the need to dip into deserializing raw .scip file in the time that I’ve been working with SCIP.

Oh, not SICP.

... and not the solver for mixed integer (linear) programming (MI(L)P) and mixed integer nonlinear programming (MINLP):

damn that is a cute logo, what a miss for SCIP-code

This is what I clicked for.

I misread it too.

Also not SCPI (Standard Commands for Programmable Instrumentation), widely used to control lab instruments and pronounced similarly ("skippy").

Nor the other SCIP.

https://en.wikipedia.org/wiki/Secure_Communications_Interope...

Or the other other SCIP: https://www.scipopt.org/

Or this SCIP https://www.scip.ch/en/

There IS no… wait, wrong acronym.

The similar acronym appears to be intentional:

> Note on the name: SCIP is pronounced the same way as “skip” and it’s a recursive acronym that stands for “SCIP Code Intelligence Protocol.”

> SCIP is also a purposeful nod to SICP (Structure and Interpretation of Programs), a book about analyzing programs.

Imagine working for this company where engineers don’t know about SICP

SCIP is a "nod" to SICP

Also not this SCIP: https://www.scipopt.org/

And also not SCP.

At least, not that we remember.

I have been using https://github.com/jacktasia/dumb-jump to quickly jump to definitions. LSP is hit or miss; in some languages, it works great, while in others, the implementation is not so good. I have been thinking about a middle ground based on Tree-sitter. GitHub uses Tree-sitter to power code navigation, but unfortunately, I can't find anything good that I can use offline. Why is there no ctags equivalent powered by Tree-sitter?

It looks like GitHub's tree-sitter powered code navigation is no longer maintained: https://github.com/github/stack-graphs

Something something powers go to definition… is this an implementation of an LSP server? Or a subset of what’s needed to implement LSP? A formerly proprietary alternative to LSP?

In its simplest form, it's just a dump of the code intelligence information from a static copy of the code. This can power an LSP, however, without additional logic wouldn't be able to handle a project under edit, since the locations won't match between the indexed state and the edited project state; So it lends itself well for something like Sourcegraph that already displays a static copy of the codebase.

Uber uses SCIP as part of the LSP implementation for our Java monorepo (Pieces of which we've [open-sourced](https://github.com/uber/scip-lsp)). Standardizing on SCIP has helped us generalize tools to be independent of the compiler/language ecosystem (eg we could do call-stack-analysis on any project that exports valid SCIP; do feature flag cleanup; find refs/impls across a wider scope than most LSP servers can handle due to memory constraints).
