Emacs-wgrep

I’ve never noticed any perceptible latency using iedit[1] in Emacs, which does what it sounds to me like you are describing. It does suggest a possible multigap buffer structure though for efficiently doing simultaneous edits of distant locations in very large files. In that case though I’d probably be iediting a small wgrep[2] buffer anyhow so it might not really matter. [1] https://github.com/victorhge/iedit [2] https://github.com/mhayashi1120/Emacs-wgrep

Oh yeah, it gets even more interesting in large refactors, say an involved rename that requires you check the context before you do so (like not just global search and replace). I do a search, this opens a buffer with all results, with file name, position, all that, and Emacs can allow you to "peek" into the file without even leaving the search buffer focus (i.e use a split screen). Then, use https://github.com/mhayashi1120/Emacs-wgrep to do the magic of in-place editing.

The `Emacs-wgrep` [1] package is what allows you to edit a standard Emacs grep buffer and have the specified changes applied to all the project's files. I just recently started using it, and it's extremely handy! [1]: https://github.com/mhayashi1120/Emacs-wgrep

I do things like that inside Emacs with the consult-grep command from the Consult package, combined with the Orderless matching style, Embark to collect the results in a buffer. This has several advantages over the command line: - Interactivity: the results are updated live as you type, so you catch typos sooner and can tweak the search terms as you go. - The buffer of search results you collect with Embark is not dead text like it would be in the terminal, instead, each line is a link to the corresponding file taking you to the line that matched. - Wgrep lets you edit all the matching lines in place!
