Subject: Bug#1099626: cpan5.40-x86_64-linux-gnu.1: Some remarks about this man
 page
Message-ID: <174120776758.2477.13116501165240458221.reportbug@kassi.invalid.is>

Package: libperl5.40
Version: 5.40.1-2
Severity: minor
Tags: upstream

   * 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=10 -ww -z < "man page"

  [Use "groff -e ' $' -e '\\~$' <file>" to find obvious 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?

troff:<stdin>:262: warning [page 3, line 42]: cannot break line
troff:<stdin>:264: warning [page 3, line 45]: cannot break line


   * What outcome did you expect instead?

     No output (no warnings).

  General remarks and further material, if a diff-file exist, are in the
attachments.

-.-.

Wrong distance between sentences in the input file.

  Separate the sentences and subordinate clauses; each begins on a new
line.  See man-pages(7) ("Conventions for source file layout") and
"info groff" ("Input Conventions").

  The best procedure is to always start a new sentence on a new line,
at least, if you are typing on a computer.

Remember coding: Only one command ("sentence") on each (logical) line.

E-mail: Easier to quote exactly the relevant lines.

Generally: Easier to edit the sentence.

Patches: Less unaffected text.

Search for two adjacent words is easier, when they belong to the same line,
and the same phrase.

  The amount of space between sentences in the output can then be
controlled with the ".ss" request.

Mark a final abbreviation point as such by suffixing it with "\&".

Some sentences (etc.) do not begin on a new line.

Split (sometimes) lines after a punctuation mark; before a conjunction.

  Lines with only one (or two) space(s) between sentences could be split,
so latter sentences begin on a new line.

Use

#!/usr/bin/sh

sed -e '/^\./n' \
-e 's/\([[:alpha:]]\)\.  */\1.\n/g' $1

to split lines after a sentence period.
Check result with the difference between the formatted outputs.
