Enhance on helm-swoop and helm-occur for Emacs

helm-rg-occur

About

helm-rg-occur is elisp package to enhance the performace of helm-swoop https://github.com/emacsorphanage/helm-swoop and helm-occur https://github.com/emacs-helm/helm on large size file, by using the ripgrep to do the grep on the file content.

If the file is in large size, such as 10M, both helm-swoop or helm-occur is quite slow, and Emacs will be blocked. But with helm-rg-occur, it is quite fast, and no performance issue.
