Description:

The motivation for this package was to develop functions for an
interactive display of two-dimensional arrays of data, for example
character tables. They should be displayed with labeled rows and
columns, the display should allow some markup for fonts or colors, it
should be possible to search for entries, to sort rows or columns, to
hide and unhide information, to bind commands to keys, and so on.

To achieve this our package now provides three levels of functionality,
where in particular the first level may also be used for completely
other types of applications:
- A low level interface to ncurses: This may be interesting for all
kinds of applications which want to display text with some markup and
colors, maybe in several windows, using the available capabilities of
a terminal.
- A medium level interface to a generic function NCurses.BrowseGeneric:
We introduce a new operation Browse which is meant as an interactive
version of Display for GAP objects. Then we provide a generic
function for browsing two-dimensional arrays of data, handles labels
for rows and columns, searching, sorting, binding keys to actions,
etc. This is for users who want to implement new methods for browsing
two-dimensional data.
- Applications of these interfaces: We provide some applications of the
ncurses interface and of the function NCurses.BrowseGeneric. These
may be interesting for end users, and also as examples for programmers
of further applications. This includes a method for browsing
character tables, several games, and an interface for demos.
