eregex.vim VS vim-ripgrep

I think eregex.vim was the plugin I last saw that did this, but I haven't tried it. I don't like putting too much between me and /. I use /\v when I want something closer to PCRE.

<\{4,} this is your answer. How I can get this in few seconds? Am I master of pattern in vim? No, I use eregex.vim. I just press <{4,} on the buffer and run :E2v under the line, and the answer is coming out.

But I mostly use ctrlp when I work with projects. A can recommend vim-ripgrep too, it lets you find strings/patterns in your project files.

I use vim-ripgrep and the result is directly addressed into the quickfix.

Sometimes I still use https://github.com/jremmen/vim-ripgrep to ripgrep non-interactively with more complex searches over bigger projects, which populates the quickfix list, the rely on bqf for extra functionality

which is what I was looking for in this regard, it allows you to specify rg arguments, like -tlua to only search in lua files for example. For me this was something that was missing, I was using https://github.com/jremmen/vim-ripgrep before that, which I still use as it is muscle memory.

In emacs we can do incremental search through an entire directory with projectile-ripgrep. The only thing I know that works more or less the same in vim is https://github.com/jremmen/vim-ripgrep, but the results only appear after I enter the hole expression and press enter, and not incrementally. Also, projectile-ripgrep lets me use a regex instead of just normal text as a query.

project-wide search (I use vim-ripgrep but any grep-finder would do)

I'm running the kitty terminal emulator with fzf and https://github.com/jremmen/vim-ripgrep installed and integrated w/ VIM-Vi IMproved 8.2 (or I believe I do). Please refer to this github link to see my vimrc.

I’m no expert, but I believe ripgrep will do PCRE, and there are more than a couple vim plugins that’ll leverage it. I happen to use vim-ripgrep, which is good enough for me, but not sure if it’ll let you get at the PCRE option (I’d guess it should, but I haven’t checked).

If the symbol has a fairly unique name you can do something like 'grep word under cursor', there are many ways to do this, I tend to use https://github.com/jremmen/vim-ripgrep, also just :h vimgrep. For more complicated cases maybe write some minimal vimscript/lua code to for example use a more specialized grep pattern in a specific directory and make a keymap for that or something.

My question is simple: Why do we need plugin like: (jremmen/vim-ripgrep)[https://github.com/jremmen/vim-ripgrep]
