omycronII - known problems
--------------------------

(1) Problems caused by erronious curses libraries

    Platforms:

        * HP-UX (sometimes)
        * Solaris/sparc (sometimes)
        * Windows

    Symptoms:

        * are high CPU load made by omycron
        * crashes

    Solution:

        * edit ${HOME}/.omycron/.omycronrc

            change:        newmainloop 1
            into:          newmainloop 0

            save and exit (omycron: exit with "xx")


    Background:

        The timeout functions of ncrurses on several platforms are implemented wrong.
        omycron has a main loop inside waiting for keystrokes. There are two
        implementations of this loop:

        (1) the old main loop, which handles every character like a real pressed key.
            When dropping text into omycron with the mouse this implementation is
            slowly and due to this exists an new loop.

        (2) the new main loop. It handles characters much more intelligent, but it
            needes a correct working implementation of the timeout functions.



(2) Problems caused by strange keycodes

    Platforms:

        * AIX

    Symptoms:

        * wrong behaviour when pressing a key

    Solution:

        * message to the author: norman.krebs@kohnos.net

    Background:

        * EBCDIC (?)



(3) Problems caused by exotic terminals

    Platforms:

        * HP-UX, IRIX

    Symptoms:

        * slow scrolling, strange output (vi has problems here too - I'm not the only poor)

    Solution:

        * not known

        * try another terminal emulator

    Background:

        * not known



(4) Problems caused by wrong environment settings

    Platforms:

        * all, but especially old, proprietary UNICes

        * gnome-terminal, SuSE, RedHat

    Symptoms:

        * wrong keys

        * wrong presentation

    Solution:

        * try to change the settings for these variables:

            TERM=linux,xterm,vt220
            LANG=en_US
            LANGUAGE=en
            LC_ALL=en_US

        * try another terminal emulator

    Background:

        * stupidity of distributors, UTF-8 etc.



(5) Omycron may crash when opening non-text files/binaries

    Platforms:

        * all

    Symptoms:

        * segfault and crash

    Solution:

        * not yet, sorry.

    Workaround:

        * run omycron with the parameter "-R-", p.e.:

            _ed <filename> -R-

    Background:

        * automatic tabulator expansion fails on some of these files
