Teehee,

"Off-by-one" is about your editor don't highlight leftmost pixel column at start of the selection.

Undo (journaling) is the conception that dictates some and outlines most of your decisions about data structures representing source text.

Real-world assembly programs' sources can be megabytes long.

It collapses lines. So it doesn't care about where selection start.



Hmmm..

Teehee,

Consider simple case: you need to invent program to manage database with single table with records of fixed size, rollback functionality implied.

Extend it to variable-sized records.

Upgrade it to support capability for partial record update/rollback.

for example ? (but please,not a disassembled one)

hopcode,

Do you think BIOS is written in HLL? I didn't mean "single multi-megabyte assembly language source file".

don't worry... who really cares of it

hopcode: I don't think asking for examples is the way to think about it.

It might be that no one ever in the whole world has ever made an assembly file larger than 1MB. But that still should not influence your decision about how to handle large files. You never know how your program will be used by either yourself or others in the future. Maybe it will be a really great editor and people want to use for all sorts of editing other than just assembly files. You just never know. But if you make it such that handling large files becomes a really slow and painful process then you can guarantee that people won't use it due to limitations.
