    Notcurses

    Notcurses

    blingful character graphics/TUI library. definitely not curses

    A library facilitating complex TUIs on modern terminal emulators, supporting vivid colors, multimedia, threads, and Unicode to the maximum degree possible. Things can be done with Notcurses that simply can't be done with NCURSES. It is furthermore fast as shit. What it is not: a source-compatible X/Open Curses implementation, nor a replacement for NCURSES on existing systems. Notcurses abandons the X/Open Curses API bundled as part of the Single UNIX Specification. For some necessary background, consult Thomas E. Dickey's superb and authoritative NCURSES FAQ. As such, Notcurses is not a drop-in Curses replacement. Wherever possible, Notcurses makes use of the Terminfo library shipped with NCURSES, benefiting greatly from its portability and thoroughness. Notcurses opens up advanced functionality for the interactive user on workstations, phones, laptops, and tablets, possibly at the expense of e.g. some industrial and retail terminals.

    Procbyte - Binary Scripting Language

    Script language for processing binary data

    Procbyte is a tool to access binary files from shell programming. It has binary data handling, read/write capability, basic math and date conversions. It is intended to aid in bash programming, but can be used from any command line tool or application. NOTE: This was accidentally uploaded as a beta, instead of alpha, but its status IS ALPHA. The next upload will standardize the language to the point where any scripts that work in it will work in all future versions -- however, scripts written for this version may not work in subsequent ones, the (mostly output) commands have changed: , ; . =* etc. Sorry for that, but I had to rework a bit to get more possible tokens and increase future expandability. If there's demand, I'll include a converter for old scripts, either as a filter or command-line interpreter so you'll be able to pipe through an additional step or use `convert_old_procb "MY-OLD-SCRIPT"` or something like that.
