Because there are many packages around > but I can't estimate their popularity. I can talk about Cscope. It is a very different tool from the others mentioned, since it supports only C (the Cscope web page claims it is useful for C++ and Java, but I think that is being generous). There are a lot of Cscope interfaces for GNU Emacs. In 2017 I looked at most of them and concluded that Robert Jarzmik rscope[1] was the most robust and easiest to work with. In particular, it worked very well with Tramp. I wanted something that was based on compilation-mode and followed modern GNU Emacs conventions (in particular, multi-occur), so I took Jarzmik's work and made a package called rcscope[2]. I have not submitted it to ELPA/MELPA yet, because I want to add editing functionality that works in the same way as wgrep-mode, and clean up some mistakes I made in how configuration is done, before releasing. It should be straightforward to add ivy support to the package. Vladimir [1] https://github.com/rjarzmik/rscope [2] https://github.com/vsedach/rcscope
