-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2017-bc7429fe09 2017-07-31 14:28:20.562967 --------------------------------------------------------------------------------
Name : gap-pkg-browse Product : Fedora 26 Version : 1.8.7 Release : 1.fc26 URL : http://www.math.rwth-aachen.de/~Browse/ Summary : GAP browser for 2-dimensional arrays of data 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.
-------------------------------------------------------------------------------- Update Information:
Changes in version 1.8.7: - Removed the example application 'BrowseTransitiveGroupsInfo', because of changes in the underlying library of transitive groups. - Added the new application 'BrowseBibliographyGapPackages'. (This is experimental, strange *.bib files in package distributions may cause error messages.) - Added a new application that facilitates demos of GAP code, see '?Browse: Utility for GAP Demos' for details. - The input code 127 is assumed to denote the backspace key also if 'NCurses.keys.BACKSPACE' has a different value, which apparently happens for some Mac operating systems; up to now, entering backspace had no effect with such systems. [This bug had been reported and analyzed by Max Horn.] - 'NCurses.Select' now supports the replay and log features of 'NCurses.BrowseGeneric'. Note that meanwhile several applications call 'NCurses.Select', now we can provide examples for them that are processed automatically, and debugging is easier. --------------------------------------------------------------------------------
