indentation in code examples is lost

[reinerh]

Some manpages have source code examples, like scanf(3).
The generated HTML page loses the indentation, which doesn't look very nice.

Thanks for the report.

Manpage rendering is done by mandoc(1).

The indentation is present when rendering to stdout:

$ curl https://manpages.debian.org/jessie/manpages-dev/scanf.3.en.gz | mandoc
[…]
EXAMPLE
       To use the dynamic allocation conversion specifier, specify m as a
       length modifier (thus %ms or %m[range]).  The caller must free(3) the
       returned string, as in the following example:

           char *p;
           int n;

…but not when rendering to HTML:

$ curl https://manpages.debian.org/jessie/manpages-dev/scanf.3.en.gz | mandoc -Thtml
[…]
<h1>EXAMPLE</h1> To use the dynamic allocation conversion specifier, specify <b>m</b> as a length modifier (thus <b>%ms</b> or  <b>%m[</b><i>range</i><b>]</b>). The caller must <b>free</b>(3) the returned string, as in the following example:<br/>
<div class="spacer">
</div>
<br/>
char *p;<br/>
int n;<div class="spacer">
</div>
<br/>
errno = 0;<br/>
n = scanf(&quot;%m[a-z]&quot;, &amp;p);<br/>
if (n == 1) {<br/>
    printf(&quot;read: %s\n&quot;, p);<br/>
    free(p);<br/>
} else if (errno != 0) {<br/>
    perror(&quot;scanf&quot;);<br/>
} else {<br/>
    fprintf(stderr, &quot;No matching characters\n&quot;);<br/>
}<br/>
<br/>
<div class="spacer">
</div>
As shown in the above example, it is necessary to call <b>free</b>(3) only if the <b>scanf</b>() call successfully read a string.</div>
<div class="section">

This is reproducible with the mandoc version in Debian testing (1.13.3-3), and with a CVS checkout from yesterday.

Would you like to report this issue upstream? If you’d prefer, I could do that for you.
See http://mdocml.bsd.lv/ for the upstream website.

Thanks for clarifying that the pages are generated with mandoc.
I just had a look at the current upstream version and noticed that this is already known and on their TODO list.

[stapelberg]

This has been fixed upstream. Re-opening this issue to track the rollout of the new version to manpages.d.o.

This is now live.
