Bug 23579

Description Eric Nickell 2002-09-13 17:58:36 EDT

I developed for many years (since 1984) using Cedar's node-structured editor,
Tioga, developed my Michael Plass, a student of Knuth.

Those who use Tioga for developing code use a node for each line of code.  When
a line cannot fit the available viewing space, Tioga soft-wraps the code onto
the next line, in accordance with the style rules which apply to the current
node.  Most developers have this be a hanging indent, so that long lines remain
distinguishable to the eye, the flow of the code reading is not interrupted,
modifications to the line don't require the developer to reformat the lines
manually, and the code stays readable when the window changes size, since Tioga
then reformats the node for the current boundaries.

I'd like to see JDT's editor have this same feature:
1) soft wrap is enabled by a Preference. When enabled...
2) Lines of code which cannot fit entirely in the current
   screen are soft-wrapped
3) Lines are broken at the last visible token boundary
4) Remainder of line is displayed on next line at same
   indentation plus 3 tab-equivalents.
5) The effects are in the display only; no actual new lines
   are inserted into the code.
