I've seen this demonstrated before in various screencasts and can't find it searching through the docs. I do use helm-swoop-edit quite often in a single buffer but when I need to change all occurrences across a project it gets a bit tedious.

For bonus points if there is a utility function to build such a buffer from helm results? I'd be very interested as my general project searching methods are helm-git-grep, helm-do-grep and helm-do-ag.

  • If not using helm, ag + multiple cursors / query-replace-regexp can do a very good job.

  • @kaushalmodi: ahh wgrep-mode is what I want. M-x helm-git-grep, action [f3] "Save results to grep buffer", wgrep-change-to-wgrep-mode.

It's documented in helm's wiki: 8.10. Save grep session, when using helm-occur/helm-do-grep/helm-do-ag, you can use C-x C-s to save search result to buffer, after installing wgrep-helm, you can use wgrep's commands to edit that buffer.
