Bug 104882 – man-1.6a doesnt consider unicode properly

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Sergey Belyashov 2005-09-05 05:21:55 UTC]

ebuild for man-1.6-r1 don't correct determine langauges from LINGUAS variable. 
It use incorrect detection method by man pages. For some languages man pages not 
included in this package, but man support help on this language. For example, 
Russian.

Reproducible: Always
Steps to Reproduce:
1. LINGUAS="en ru" USE="unicode nls" emerge '=man-1.6-r1'
2. LANG=ru_RU.UTF-8 man --help

Actual Results:  
Help on English

Expected Results:  
Help on Russian

I try to solve this bug (and others) and write my version of ebuild (http://
bugs.gentoo.org/attachment.cgi?id=67503).

that iconv stuff doesnt belong in the ebuild

ive changed the `strip-linguas` to read the value from configure so that 'ru' is
allowed

Created attachment 68084 [details, diff]
man-unicode.patch

try this patch

i think we also need to re-encode the included manpages too in man/??/*.man

I try it. Russian detects correctly. But result is bad - gabage on screen if I 
run 'man --help'. I think, that 'unicode' target do not start from Makefile. (If 
I manually convert messages, then all OK).

With reencoding man pages may be problems. Example:

I emerge man-pages-ru.
Because it in KOI8-R I encode any page (for example cp.1) to utf8 (with iconv)
Try to see what is in (before I copy this page to /usr/share/man/ru/man1)
Result is very very unreadable ('DoXD0XODOSIO' etc., it is not cyrilic ;) ).

I think, if You reencode buildin man-pages then some pages will be unreadable. 
It's need to patch man (or troff) sources...

This http://bugs.gentoo.org/show_bug.cgi?id=104593 bug is about problem with man 
pages in utf8.

[Comment 5 SpanKY 2005-09-11 15:22:21 UTC]

if you emerge man with the proposed patch and USE=unicode, then the code pages
should have been re-encoded ...

can you run `emerge man >& log` and post the log as an attachment ?

[Comment 6 SpanKY 2005-09-11 15:49:07 UTC]

man-unicode.patch

how about this one

[Comment 7 Sergey Belyashov 2005-09-12 05:53:41 UTC]

log of emerge man

Your new patch is working properly for Russian, but may be problems with
Korean.  ;) See attachement.

[Comment 8 Sergey Belyashov 2006-07-04 10:42:16 UTC]

Fixed by sys-apps/man-1.6a-r1

[Comment 9 Sergey Belyashov 2006-07-04 10:46:33 UTC]

Created attachment 90869 [details]
sys-apps/man/man-1.6a-r1.ebuild

Sorry. It is my own ebuild.

[Comment 10 Sergey Belyashov 2006-07-04 10:59:17 UTC]

sys-apps/man-1.6-r1 also works properly when add key '--manpage' to the NROFF command.
May be it need to make by ebuild?

[Comment 11 Sergey Belyashov 2006-07-04 10:59:27 UTC]

sys-apps/man-1.6-r1 also works properly when add key '--manpage' to the NROFF command in /etc/man.conf.
May be it need to make by ebuild?

[Comment 12 Sergey Belyashov 2006-07-04 11:02:45 UTC]

--manpage is key of patched (by me) groff. :)

[Comment 13 SpanKY 2006-07-04 12:16:22 UTC]

ive contacted upstream man maintainer about unicode in man and they're working on it ... really i think you should look at man-1.6d and also work with the upstream maintainer to get this resolved ... i have no problem admitting that this is beyond my capabilities to make sure it gets done right ;)
