Undesirable space after parenthesis in HTML output

Undesirable space after parenthesis in HTML output

Hi!

For following sequence in manpage

  Name (\fItest@example.org\fR)

mandoc's HTML output prints following:

  Name ( <i>test@example.org</i>)

It adds additional space after left parenthesis, which looks really
horrible.

In utf8, ps and pdf outputs it is correct without additional space:

  Name (test@example.org)

With -current mandoc code, i can't seem to reproduce your issue:

$ echo 'Name (\\fItest@example.org\\fR)' | mandoc -T html | grep Name
<div class="manual-text">Name (<i>test@example.org</i>)</div>

Which version of mandoc are you using?  Please state:
 - operating system name and version
 - whether contained in the base system, installed from a package,
   or compiled from source
 - if from a package, package manager name (e.g. pkgsrc, homebrew, dpkg)
   and package name and version number
 - if from source, tarball name or CVS checkout date and time

Yes, that is how it is supposed to look like.

Yours,

Hi! Try this:

$ printf "%s\ntest test test test test %s\n" 'Name (\fItest@example.org\fR)' 'Name (\fItest@example.org\fR)' | mandoc -T html

I got following output:

<div class="manual-text">Name (<i>test@example.org</i>) test test test test test
  Name ( <i>test@example.org</i>)</div>
<table class="foot">

First Name is correct, second Name not.

Just for verification:

$ printf "%s\ntest test test test test %s\n" 'Name (\fItest@example.org\fR)' 'Name (\fItest@example.org\fR)'
Name (\fItest@example.org\fR)
test test test test test Name (\fItest@example.org\fR)

Debian 9.6

Tested both which is available in the repository and also compiled from
source which is available from "Newest release tarball" at
https://mandoc.bsd.lv/

$ apt install mandoc

current package version is 1.13.3-3+b1

"Newest release tarball" downloaded 2018-11-22.

Ah.  Yes, i can reproduce that on -current.

It wasn't even related to parentheses.  The bug simply caused output
of whitespace in the middle of words when there were font escape
sequences - though not always.  Whether the bug hit depended on the
spacing mode before the word containing the font escape, which made
it a bit elusive.

Fixed in the following commit.

Thanks for reporting the bug,
  Ingo

I just spotted it on lot of places around email addresses generated by
pod2man, therefore I thought it is related to parentheses around.
