Sébastien Brisard commented on MATH-852:
----------------------------------------

* I prefer non-closing <p> tags on a separate line, this is much more readable
and takes less space
{quote}
The reason why I proposed this rule is that I think we should be ready for
xhtml (which is again not yet enforced by the standard doclet). For example,
including some MathML in the javadoc would require strict xhtml. I'm using
mathml in some other projects (I know I should be writing a user's guide
instead...). However, I'm not sure that it will be ever used in Commons-Math,
so I'm happy with this proposal (or even better: no rule at all).

I am not sure about the indentation of the long comment, but I normally use two
spaces in the next line to make a better distinction with the next tag, like
this (but could also use more spaces)
{quote}
This is merely reflecting what's currently done in the library. I previously
used the formatting suggested in the tutorial you've pointed at, but it must be
owned that you get used very quickly to the CM common practice.
> Improvements to the Developer's Guide
> -------------------------------------
>
> Key: MATH-852
> URL: https://issues.apache.org/jira/browse/MATH-852
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Sébastien Brisard
> Labels: formatting, guidelines
>
> Recent discussions (see MATH-851, as well as these threads
> [1|http://markmail.org/thread/utxuipyolpnche5o],
> [2|http://markmail.org/thread/sma3nwa5j3hspvp5]) have shown that our actual
> requirements (especially regarding formatting) are higher than stated in the
> Developer's Guide. This leads to confusion among new contributors, as well as
> recent committers. It is therefore proposed to revise this guide, in order
> for it to reflect the actual expectations regarding submitted code.
> This guide should however not act as a deterrent for new contributors, so
> attention should be paid to "rules" we consider as essential vs. superfluous
> rules.
> Here is an extract of the developer's guide in its current state
> h3. Coding Style
> Commons Math follows [Code Conventions for the Java Programming
> Language|http://www.oracle.com/technetwork/java/codeconv-138413.html]. As
> part of the maven build process, style checking is performed using the
> Checkstyle plugin, using the properties specified in checkstyle.xml.
> Committed code should generate no Checkstyle errors. One thing that
> Checkstyle will complain about is tabs included in the source code. Please
> make sure to set your IDE or editor to use spaces instead of tabs.
> Committers should make sure that svn properties are correctly set on files
> added to the repository. See the section on Committer Subversion Access on
> the Apache Source Code Repositories page.
> h3. Documentation
> * Committed code must include full javadoc.
> * All component contracts must be fully specified in the javadoc class,
> interface or method comments, including specification of acceptable ranges of
> values, exceptions or special return values.
> * External references or full statements of definitions for all mathematical
> terms used in component documentation must be provided.
> * Implementations should use standard algorithms and references or full
> descriptions of all algorithms should be provided.
> * Additions and enhancements should include updates to the User Guide.
