vim-gutentags VS fzf

https://github.com/ludovicchabant/vim-gutentags/issues/139 has some background.

Hi everyone. I'm looking to have a better setup for Rust in neovim. I do have rust-analyzer installed for useful lsp things but I was hoping to get tags working for it as well. I was using vim-gutentags (https://github.com/ludovicchabant/vim-gutentags) for navigating useful functions and stuff but couldn't quite get it to work for rust. Is there a simple way to do it or do I need rusty-tags and some aucommand to get it to work?

use tags, I like https://github.com/ludovicchabant/vim-gutentags for this. I might use my local .vimrc to tweak the config (exclude compiled source files and other uninteresting things)

Without more information, it's hard to point you in the right direction. The tags file could be out-of-date, in which case you can try to re-generate it (vim-gutentags for tags auto-generation). You could have 2 function declarations with the same name, in which case you can try :tag to cycle through tags (supports partials, like :tag F which will suggest FOO, FAR, FAB ...etc) or :tag to see a list of possible options (supports partials, like :tag F which will list FOO, FAR, FAB, ...etc) for various matching tags you can jump to (fzf.vim provides a tags fuzzy finder via :Tags). Maybe you're experiencing :h tag-priority?

You can then use :cnext and :cprev (or focusing the window and selecting an entry) to navigate between them.

As others have stated, you can also use ctags (plugins like https://github.com/ludovicchabant/vim-gutentags are useful for refreshing tags in a project), but for some languages you may need to add a tag definition (e.g. for something like rust or zig). For older languages like C you should be fine.

Not sure if it will help in this case, but I also depend on ctags for when the lsp fails (e.g. code it doesn't compile for some reason). Here you let a program create a tags file, e.g. I use https://github.com/universal-ctags/ctags (it seems it can parse json files, though I'm not sure what kind of tags are generated from this and if they will be useful to you) with https://github.com/ludovicchabant/vim-gutentags to update the tags file. The tags file just contains symbol names with locations where they are defined, and vim has builtin functionality to use these tags files :h tag and they (can) work filetype independent. For example if I mention a C type in a markdown document I can just use ctrl-[ to jump to its definition in the C source file. Possibly you can generate tags files yourself from the json files to help with this, the tags file format is not very complicated. Tags also are not very intelligent and depend on unique names for them to work well, there is the :h g_CTRL-] that can help, but for symbols that are very common (e.g. init or something that potentially has like 20+ definitions) it doesn't really work.

In addition, I think bash's `operate-and-get-next` can be very helpful. When you go back through your shell history, you can hit Ctrl+o instead of enter and it will execute the command then put the next one in your history on the command line, and keep track of where you are in your history. This way, you can rerun a bunch of commands by going to the first one and Ctrl+o till you are done. And you can edit those commands and hit Ctrl+o and still go to the next previously run command.

Note: fzf's history search feature breaks this. https://github.com/junegunn/fzf/issues/2399

fzf : https://github.com/junegunn/fzf

Those are the most used aliases in my gitconfig.

"git fza" shows a list of modified/new files in an fzf window, and you can select each file with tab plus arrow keys. When you hit enter, those files are fed into "git add". Needs fzf: https://github.com/junegunn/fzf

"git gone" removes local branches that don't exist on the remote.

"git root" prints out the root of the repo. You can alias it to "cd $(git root)", and zip back to the repo root from a deep directory structure. This one is less useful now for me since I started using zoxide to jump around. https://github.com/ajeetdsouza/zoxide

> my history is so noisy I had to find another way

The fzf search syntax can help, if you become familiar with it. It is also supported in atuin [2].

[2]: https://docs.atuin.sh/configuration/config/#fuzzy-search-syn...

You call it with `n` and get an interactive fuzzy search for your directories. If you do `n ` instead, it’ll start the find with `` already filled in (and if there’s only one match, jump to it directly). The `ls` is optional but I find that I like having the contents visible as soon as I change a directory.

I’m also including iCloud Drive but excluding the Library directory as that is too noisy. I have a separate `nl` function which searches just inside `~/Library` for when I need it, as well as other specialised `n` functions that search inside specific places that I need a lot.

I do find the history pager stuff interesting, but ultimately not of tremendous use for me. I rebound all my history search stuff to use fzf[1] (via a fish plugin for such[2]), and so haven't been aware of the issues

You can also use fzf with ripgrep to great effect:
