Bug 20006 – [PATCH] Wide character (UTF-8) support for ncurses

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sascha Silbe 2003-04-26 10:44:16 UTC]

The attached patches (for ncurses-5.3-r1.ebuild and for ncurses-5.3 source) enable wide character support in ncurses (if the USE variable "nls" is set) without renaming the library to ncursesw. So the other ebuilds (like mutt) do not have to be changed for UTF-8 support.



Reproducible: Always
Steps to Reproduce:
1. cd /usr/portage/sys-libs/ncurses
2. cp ncurses-5.3-r2.ebuild ncurses-5.3-r2.ebuild
3. patch < ~/ncurses-5.3-r2.ebuild.patch
4. cp ~/ncurses-5.3.utf8normal.patch files
5. ACCEPT_KEYWORDS=~x86 emerge ncurses

Actual Results:  
mutt displayed German umlauts correctly even with LC_CTYPE=en_US.UTF-8.


Expected Results:  
Exactly that. :)

Patch for ncurses-5.3 so it does not rename itself to ncursesw if using --enable-widec

Patch for ncurses-5.3-r1.ebuild to enable wide character (UTF-8) support

[Comment 3 Zhen Lin 2003-09-01 05:32:49 UTC]

I think it is bad to rename ncursesw to ncurses - some apps rely on ncursesw being a seperate library.

Perhaps symlinks and ldscripts would be better.

I was going to submit a enhancement request for this - but you beat me to it.

I am opposed to overloading the USE flag nls in this manner - this should come under unicode, utf8 or widec.

[Comment 4 Thomas Raschbacher 2003-12-08 23:26:09 UTC]

adding a dep since this has kinda to do with 18375

[Comment 5 Lars Weiler (RETIRED) 2004-03-17 18:21:02 UTC]

Did you ever tested to compile vim with your patch?  Mine broke with a ncurses-w library only...

[Comment 6 Panard 2004-08-10 16:28:29 UTC]

tried with ncurses-5.4-r3 and vim-6.3, all is fine :)
I attach my ncurses ebuild ( with IUSE="unicode" ), the patch is the same

I need this patch in portage, so please test it ;)

Thanks.

utf-8 support is now in ncurses-5.4-r4

[Comment 9 Sascha Silbe 2004-08-19 15:18:03 UTC]

Works fine now, at least for mutt.
Thanks!
