eyebrowse VS helm-swoop

An Emacs package is just Emacs Lisp code that adheres to package conventions. If you can write moderately complicated code in your init file and believe that it may be useful to other people, put it into its separate file, add package headers/footers, adjust to package writing conventions and it's ready for publishing. I've learned all that from looking up the documentation and most importantly, studying other packages. I was at that point one year into my Emacs journey and published https://github.com/wasamasa/eyebrowse shortly after.

I am thinking myself of whether swiper/swoop functionality can entirely replace isearch, or whether it is better kept separate. You never use isearch at all?

Helm-swoop https://github.com/emacsorphanage/helm-swoop

The easiest way of doing this is using M-x occur which might be bound to M-s o by default. This will involve typing out the search string. I like using helm-swoop which I've bound to M-i, which searches for the thing at point, which is faster. Both of these tools generate the sparse buffer and let you jump around the file. The advantage of using occur is that you can invoke edit and then modify one or more occurences directly in the occur buffer.
