ncurses or slang
Dear All, what is the preferred screen output library in the upcoming mc 4.7 and current pre2? I.e. if one can install both ncurses and slang2 on his system what mc is to be compiled against, what branch is developed and tested more active, where are bugs fewer and features more abundant?

Hi! I like ncurses: the versions with full Unicode support are available on vintage distros like RHEL4 RHEL3. -- Sincerely yours, Yury V.

Sorry can't check right now, but I think it worked once I've got the static glib thing just as it did for RHEL4. It's been like 3-4 months ago... -- Sincerely yours, Yury V.

Dear Slava, what is the preferred screen output library in the upcoming mc 4.7 and current pre2? Preferred to S-Lang (as default), but Ncurses fully supported too. With NCurses we have some restrictions (like trouble with drawing of double lines for boxes). S-Lang is a more powerfull library. did you contact Thomas Dickey, the author of ncurses with your problems? I am not sure if he is still on this list (he used to be), but he is active at the ncurses list bug-ncur...@gnu.org and generally responsive to bug reports and helpful in solving complex usage cases.

Well... Drawing double lines possible in NCurses via tty_print_string()
function (not via hline() vline() and etc). In this case we (side of mc)
must take care of user encoding, terminal type and used current font. If
we use hline or vline functions (like now) then this headache of NCurses.
Now Midnight Commander (from git) have initial support of skins.
Possible to change drawing of lines via skin-file. With Ncurses library
we used vline, hline and ACS_* constants, therefore double lines not
drawing, but lines look good with any codepage of user. With S-Lang
library we used anoter way (in opposite): draw lines directly via
SLsmg_write_char. As result: we have any UTF-8 lines but we have trouble
in one-byte codepages ('LANG=C mc' or 'LANG=POSIX mc' show this trouble
as well).
I'm don't know how handle this situation :( We need help from all
interested persons.
WBR, Slavaz.

All that sounds just like you're using slang's equivalent of add_wch() or
addch(), which you can already do with ncurses. (Either way, the solution
depends on locale and terminal support ;-)
The one-byte codepages providing double-lines aren't available in POSIX
locale. ncurses has a use_legacy_coding() function to tell it that the
display can show characters which the locale says aren't printable (though
mixing that with a UTF-8 locale may not give good results).
