Package: imagemagick-7.q16
Version: 8:7.1.2.23+dfsg1-1
Severity: minor
Tags: patch
Additional remarks.
Mails from me to "submit at bugs.debian.org" 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.
If I get a negative (or no) response from upstream, I send henceforth
bugs to Debian.
-.-
* 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 ' \\"' <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 -t -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=0 -ww -z ":
troff:<stdin>:130: warning: trailing whitespace [-w trail]
troff:<stdin>:143: warning: trailing whitespace [-w trail]
troff:<stdin>:212: warning: trailing whitespace [-w trail]

troff:<stdin>:143: warning: trailing whitespace [-w trail]
troff:<stdin>:212: warning: trailing whitespace [-w trail]
* What outcome did you expect instead?
No output (no warnings).

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

Remove space characters (whitespace) at the end of lines.
Use "git apply ... --whitespace=fix" to fix extra space issues, or use
global configuration "core.whitespace".
See more information in the attachment "trailing whitespace".
Number of lines affected is
3
-.-.
Add a "\&" (or a comma (Oxford comma)) after an abbreviation
or use English words
(man-pages(7)).
Abbreviation points should be marked as such and protected against being
interpreted as an end of sentence, if they are not, and that independent
of the current place on the line.
44: \-features distance analyze image features (e.g. contrast, correlation)
330:By default, the image format of `file' is determined by its magic number. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output.
-.-.
Wrong distance (not two spaces, not a new line character (\n)) 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.

-.-
Generally:
Split (sometimes) lines after a punctuation mark; before a conjunction.
Generated files create bigger and more difficult to read/check patches
when the generator creats long lines, instead of shorter ones or by
postprocesing its output in such a way.
-.-
Tables:
Use the preprocessor 'tbl' to make tables.
Put data, that are wider than the header in the (centered) last column,
in a "T{...\nT}" block(, when the table gets wider than the output line).
Table headings, that are wider than any data in the corresponding
column, do not need to be centered, so left adjustment (l, L) is
sufficient.

-------------- next part --------------
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 ' \\"' <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)
