About: Customize text for closed folds Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

The foldtext function below does three things: * Is less intrusive when displaying code, and right-aligns the number of lines in the fold. * Collapses folds that start and end on braces with everything between the braces replaced with {...}. * Tries to collapse multiline comments with the first non-blank line in the comment. Outstanding issues: I also use the following highlights with white backgrounded source to visually set the folds apart from non-folded lines, while trying to keep a nice aesthetic.
