> What is a folding editor?
A text editor that structures files in a hierarchical tree structure.
At each level the branches ("folds") are usually shown as single lines
(with some fold marker to show that they're folds, not just lines) and
the editor has functions to expand a fold line into the contents of
the branch, and to collapse the current fold and go back to the
next level up. The only special formatting requirements for the files
are beginning- and end-of-fold marker strings.
This is a simplified and inadequate description, you really need to
use one before you get a feel for the concept.
I think the first folding editor was the one (written in occam 1!)
that came with the old INMOS occam Programming System. (Does
anymbody know of pre-INMOS folding editors?) The later INMOS
Transputer Development System had a similar editor built-in, and the
original version of Origami (totally unlike the current one, thanks to
Michael) was a clone of this. There's at least one other one, AE
(Andy's Editor), a free/shareware DOS text editor.
