in reply to Further on buffering huge text files

Why not leave the line numbers as they were before filtering and simply not display the filtered lines? It would look something like: 
1211 dfgsdfsdfg
1212 sdfgdfgsdf
1213 sdfgsdfgsdfg
1273 sdfgsdfgsdfg
1274 sdhgsfdg

The only problem with this approach is when the filter would filter out most (or all) of the lines in the buffer. The display would be rather empty then.

    You are absolutely right with the "only problem" you present. If you think about it, it's an unacceptable problem. Especially when most of the file is filtered out.

      Then keep reading untill the buffer is filled? The GUI would request say 120 lines starting from line 35465 (or byte/char 235435), you would start reading lines fom that position and keep reading and filtering untill you can return the 120 lines.
