What exactly you mean with "doesn't process manpages correctly"? The same thing as in Bug 102760? I mean output is not plain text; a manpage is not convert to a plain text file. I am sorry, now I realize my subject line was not informative. No, not the same bug; #102760 is a bug of `col', and its effect is truncation only. rather than blaming groff, maybe it's col's fault (Bug 102760) No, definitely not.
Output of
$ groff -t -e -mandoc -Tascii wc.1
is like this:
^[[1mNAME^[[0m
wc - print the number of newlines, words, and bytes in files
^[[1mSYNOPSIS^[[0m
^[[1mwc ^[[22m[^[[4mOPTION^[[24m]... [^[[4mFILE^[[24m]...
And, output of
$ nroff -c -mandoc -Tlatin1 wc.1
is like this:
N^HNA^HAM^HME^HE
wc - print the number of newlines, words, and bytes in files
S^HSY^HYN^HNO^HOP^HPS^HSI^HIS^HS
w^Hwc^Hc [_^HO_^HP_^HT_^HI_^HO_^HN]... [_^HF_^HI_^HL_^HE]...
The latter can be filtered correctly by `col'.
the former outputs control codes which look fine if you give it to something which understands control codes like `less` hey i'm french, i prefer to read the manual in my native your subject line is not unuseful. i saw this problem yesterday. the letter with some accents in the french man-pages are displayed like this e(C). i don't know how to fix this while i "can't" RTFM.

Scuse me for this msg Hi all,
it is a groff problem and the solution is to pass it the -c option. This can be set in /etc/man.conf. You may also compare man.conf on your suse and gentoo. (Do not mind the funny location of my man.conf, I am a alt-prefix user, but this is irrelevant.)

`man grotty` is the only man-page which for me shows colours (in the background and foreground example texts). People with garbled text seem to be able to get something useful when using man -P "less -R", while setting PAGER to "less -R" doesn't work. you need to pass these additional args: -P -c -P -b -P -B these tell the postprocessor (grotty) to not use escape sequences. the escape sequences that show up in the output are part of ascii, so the -Tascii format doesn't tell groff to filter it out. the -mandoc says you want to do things like bold/color, so it includes the escape sequences. or i could be full of crap and you should check with upstream to verify: https://lists.gnu.org/archive/html/groff/ |
