vim might very well be if it turns out you had syntax on. I've yet to have vim fail on me as long as I skip the pretty colours for big files. Then again I've had very long lines indeed but can't tell if they were that long.

My case was also a sqldump, actually. I forget what I eventually did. I think it had to do with hitting Ctrl-C to stop the entire file from loading up front, and only load the page I was looking at.

The link to this SO question was purple when I Googled this just now: http://stackoverflow.com/questions/908575/how-to-edit-multi-...

In retrospect, I do remember also messing around with disabling syntax highlighting and splitting the file up into more manageable chunks that I loaded into separate buffers.

For my purposes, I was trying to delete certain portions of the dump - so vim was the perfect tool to do something like "delete everything from line 850 to the next time this regex is matched", with a minimum of scrolling around and rendering things unnecessarily. iirc, Sublime just locked up and refused to scroll.

I wonder if I could have used Vintage to do what I wanted in Sublime?
