Package: texlive-extra-utils
Version: 2026.20260711-1
Severity: minor

  Additional remarks.

  Mails from me to "[email protected]" are no longer acknowledged.  A
Debian maintainer told me, that he would contact the mail administrator
about me not wanting to send bugs upstream.

-.-

Dear Maintainer,

>From "/usr/share/doc/debian/bug-reporting.txt.gz":

  Don't file bugs upstream

   If you file a bug in Debian, don't send a copy to the upstream software
   maintainers yourself, as it is possible that the bug exists only in
   Debian. If necessary, the maintainer of the package will forward the
   bug upstream.

-.-

  For forwarding bug reports to upstream see:

https://www.debian.org/Bugs/Developer#forward

-.-

  "Handling bug reports" in
http://people.debian.org/~enrico/dcg/ch03s02.html

-.-

  I do not send reports upstream if I have to get an account there.
The Debian maintainers have one already.

-.-

   * What led up to the situation?

     Checking for defects with a new version

test-[g|n]roff -mandoc -t -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=0 -ww -z < "man page"

  [Use 

grep -n -e ' $' -e '\\~$' -e ' \\f.$' -e ' \\"' -e ' "$' <file>

  to find (most) trailing spaces.]

  ["test-groff" is a script in the repository for "groff"; is not shipped]
(local copy and "troff" slightly changed by me).

  [The fate of "test-nroff" was decided in groff bug #55941.]

   * What was the outcome of this action?

Output from "test-groff  -mandoc  -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=0 -ww -z ":

  Check the output from "lintian" in the Debian distribution.

  Any program (person), that produces man pages, should check the output
for defects by using (both groff and nroff)

[gn]roff -mandoc -t -ww -b -z -K utf8 <man page>

  To find most trailing spaces use

grep -n -e ' $' -e ' \\f.$' -e ' \\"' -e ' "$' <man page>

  The same goes for man pages that are used as an input.

-.-

  For a style guide use

  mandoc -T lint

-.-

  For general input conventions consult the man page "nroff(7)" (item
"Input conventions") or the Texinfo manual about the same item.

-.-

  Any "autogenerator" should check its products with the above mentioned
'groff', 'mandoc', and additionally with 'nroff ...'.

  It should also check its input files for too long (> 80) lines.

  This is just a simple quality control measure.

  The "autogenerator" may have to be corrected to get a better man page,
the source file may, and any additional file may.

-.-

  Common defects:

  Not removing trailing spaces (in in- and output).
  The reason for these trailing spaces should be found and eliminated.

  "git" has a "tool" to point out whitespace,
see for example "git-apply(1)" and git-config(1)")

-.-

  Not beginning each input sentence on a new line.

Line length and patch size should thus be reduced when that has been fixed.

  The script "reportbug" uses 'quoted-printable' encoding when a line is
longer than 1024 characters in an 'ascii' file.

  See man-pages(7), item "semantic newline".

-.-

The difference between the formatted output of the original
and patched file can be seen with:

  nroff -mandoc <file1> > <out1>
  nroff -mandoc <file2> > <out2>
  diff -d -u <out1> <out2>

and for groff, using

printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -mandoc -Z -

instead of 'nroff -mandoc'

  Add the option '-t', if the file contains a table.

  Read the output from 'diff -d -u ...' with 'less -R' or similar.

-.-.

  If 'man' (man-db) is used to check the manual for warnings,
the following must be set:

  The option "-warnings=w"

  The environmental variable:

export MAN_KEEP_STDERR=yes (or any non-empty value)

  or

  (produce only warnings):

export MANROFFOPT="-ww -b -z"

export MAN_KEEP_STDERR=yes (or any non-empty value)

Subject: clean files of trailing whitespace

  Trailing whitespace is so unnecessary, that its presence may be removed
before files containing it are distributed.

  Some programs have a tool to point out its presence, like

gcc

  with option "-Wtrailing-whitespace"

git
  with option "apply --whitespace=..."

  and in ".git/config"

[core]
	whitespace=...

grep

  with option -e '[[:blank:]]$'

less

  with command "/ $"

mandoc -T lint
