Tidyall by Jonathan Swartz

Great code tidiers and validators exist for just about every language (Perl, HTML, Javascript, CSS...), but each tool has its own interface and idiosyncracies. Applying the right ones to all files in your project can be painful and error prone.

Enter tidyall: a unifying framework for code tidiers and validators. A single config file at the top of your project specifies which tools to use on which files. Besides the command-line, you can run tidyall in a variety of useful contexts: your editor, git/svn pre-commit hooks, unit tests, and Dist::Zilla builds.

The author will describe tidyall and, more generally, the benefits of enforcing common styles in a multi-developer, multi-lingual code base.

    Jonathan- Keep up the good work!
    Sonar is the Java project that is similar. Today is the last day of Manning's sale on the book; use code s645
    I also mentioned grunt.js; Yeoman is a new front-end, still in alpha

    This was better than most seminars because the length was right, short and to the point. There was lots of helpful interaction with the audience. The subject was also something that would help the programming community: getting developers to use tidy, critic, and validation utilities more.

    Very practical talk about a great new tool. I'm finally inspired to automate my code tidying now.

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.
