cppinsights VS lsif-clang

Sorry, I don't know about an Emacs plugin. All the plugins/extensions I'm aware of are listed in the Readme.md: https://github.com/andreasfertig/cppinsights/#c-insights--vi...

I'm happy to add an entry for Emacs once somebody develops a plugin for that editor.

Thank you! This is exactly the sort of thing I was looking for.

I found the source at https://github.com/andreasfertig/cppinsights

You can put it into https://cppinsights.io/ and see the conversions that happen under the hood.

I tried this at https://cppinsights.io/ to see what is generated for something like:

> http://eel.is/c++draft/ bookmark this, you will need it!

Now, about books I would suggest the latest "A tour of C++" by Bjarne Stroustrup; it's ideal for experienced programmers that want to learn modern C++ rather fast.

Other books would be Scott Meyers' Effective Series, Andrei Alexandrescu and Herb Sutter are a must, and of course Jason Turner's "C++ Weekly" series [1]; of course apart from the books, the links I have originally shared are more than enough to cover everything around C++.

https://cppinsights.io/ it's a must so you can investigate what gets generated by templates behind the scenes.

Try https://cppinsights.io. For example, go to https://cppinsights.io/s/8401262a and click the play button at the top left.

If you're doing something more complex, you might need metashell. See http://metashell.org/manual/how_to/index.html#see-what-templ.... But you have to really, deeply, love C++ to get much out of it.

In the top right corner of the tooltip it will say either "Search-based" or "Precise" - in this case, you're right, we don't have the abseil-cpp repo indexed so it falls back to search-based as you describe.

We do have a C++ code indexer in beta, https://github.com/sourcegraph/lsif-clang - it is based on clang but C++ indexing is notably harder to do automatically/without-setup due to the varying build systems that need to be understood in order to invoke the compiler.

Interesting because on https://lsif.dev/ I see that LSIF support for C++, which basically is just a wrapper around clangd AFAIU, is deprecated. Is there something else that replaced it?

We already have an LSIF indexer for C++ (lsif-clang); however, that is not as feature complete as the other indexers. Moreover, the codebase is forked off of Clang 10, so upgrading to newer Clang versions (and build a SCIP indexer on top of that) will be a challenge.

- Go:

Why are not all repos covered?

Because different languages have different build systems, so inferring the right build commands, dependencies etc. is not so straightforward; these are necessary per-requisites for compiler-accurate cross references. We're working on fixing this with auto-indexing: https://docs.sourcegraph.com/code_intelligence/explanations/...

For C and C++ specifically, auto-indexing is challenging because of the large variety in build systems, informal specification of dependencies (such as in a README instead of a machine-readable format), and platform-specific code.

Outside of auto-indexing, we do have an indexer for C and C++ right now (https://github.com/sourcegraph/lsif-clang) which can be run in CI; that way one can generate an index and upload it to Sourcegraph on a regular basis. It is 'Partially available' (https://docs.sourcegraph.com/code_intelligence/references/in...) right now. We're keenly aware of the interest in C++, and are working our way through different languages based on usage.
