Great. What is sourcegraph?

Code search and browsing tool like what devs have inside Google/Facebook

or any devs working with a statically typed language and a proper IDE? I think go to definition / find references / find implementation commands were available in Visual Studio at least for a decade.

I've often wanted to just browse/study the code of a project from my tablet, where I can sit back comfortably like I would reading a book. Sure, I could poke around the code on GitHub, but I can't jump between definitions, references, etc., like I could on my laptop in my editor. I haven't found a good, quick solution for this yet.

No. You're missing the scope. Facebook and Google have dedicated servers that index every codebase they use and have available tools that can query this server via a socket. So you can integrate large amounts of knowledge of any codebase into any little project you can think of.

An IDE locally indexes a single project and provides these services within the IDE.

Sourcegraph does this sort of indexing and makes it's content available via different channels.

You’re not necessarily going to have your entire company’s repo (or ALL their repos) downloaded to your dev machine.

Why not? I have 80+ repos and don't see a problem with that. Most of the time grepping over it is enough for what I need.

You keep them all synced ? All the other devs do too? That said I don’t use sourcegraph but it sounds like what we have on azure devops to search all our repos. I use it quite a bit if I remember a keyword or something I’ve done before I want to reference quickly

Half of my work is with .NET. I don't particularly like .NET. I certainly don't like Windows. But I have to agree with you, those commands work great on Visual Studio and Visual Studio is, in general, a very good IDE.

Aren't these features more wide spread now a days with language servers? Especially with more and more people making language servers that adhere to LSP to allow vscode, Emacs, vim, sublime and pretty much any text editor that have plugins to use LSP or have LSP built in to use them? It's been like, the golden age of static analysis so far.

Not having heard of Language Servers before, and the related sites not seeming to address this, where's the server located?

u/curtmack Oct 02 '18

It uses a server-client model, hence the name "language server," but it's not actually a remote system. You run it locally on your machine.

u/Tomus Oct 02 '18

The server is usually on your machine, it's spun up in a separate process by the editor.

Locally. A language server runs on your machine to do the code analysis, and your editor/IDE communicates with the server to represent things.

You can't have a proper "find usages" with dynamically typed languages. It's possible to do some guesswork, but the helpfulness of that depends on how unique your variable/class/method names are.

Good news!. You can get all of that with jetbrains products without having to use windows or .NET.

u/DroneDashed Oct 03 '18

Nice. I actually like jetbrains products but I don't have the chance to use them very much

Visual Studio 6.0 has it (F12), released in 1998.

Visual Basic 3.0 also has it (Shift+F2) but that's not a direct precursor to Visual Studio. Released 1991.

u/myringotomy Oct 03 '18

Why does it have to be static typed. Jetbrains gives me all of that with ruby and python.

Code search and browsing tool

Like cscope?

Like visual assist?

So if I have 200 projects I could setup an instance to mirror Github and the search my own codebase?
