Can someone point me to structures/algorithms to use for text editor which could support files of unlimited lengths (including lines of unlimited length) without loading those fully in the buffer?
I miss that editor so much, that I'm considering to write one some day, but I have no idea how to do so. I can invent things myself, but I guess those things were invented already back in the days computers were different.
That is essentially what VLF[1] does in Emacs. It reads in discrete chunks of the file at a time and doesn’t load the next one till you try to display it. Doesn’t require any fancy data structures, just some extra book keeping and mechanics.
