Artistic Style 1.21

http://astyle.sourceforge.net/


Artistic Style is a source code indenter, formatter, and beautifier for the C, C++, C# and Java programming languages.

When indenting source code, we as programmers have a tendency to use both spaces and tab characters to create the wanted indentation. Moreover, some editors by default insert spaces instead of tabs when pressing the tab key, and other editors (Emacs for example) have the ability to "pretty up" lines by automatically setting up the white space before the code on the line, possibly inserting spaces in a code that up to now used only tabs for indentation.

Since the NUMBER of space characters showed on screen for each tab character in the source code changes between editors (unless the user sets up the number to his liking...), one of the standard problems programmers are facing when moving from one editor to another is that code containing both spaces and tabs that was up to now perfectly indented, suddenly becomes a mess to look at when changing to another editor. Even if you as a programmer take care to ONLY use spaces or tabs, looking at other people's source code can still be problematic.

To address this problem, Artistic Style was created - a filter written in C++ that automatically re-indents and re-formats C / C++ / C# / Java source files. It can be used from a command line, or it can be incorporated as classes in another C++ program.

Fully Elaborated Documents As a Completion Criteria ...

In May 1988, Bary W. Bohem published an article about Spiral Model. He described the available, at this time, software models and write some of its advantages and disadvantages. I liked the following paragraph from his article.

"A primary source of difficulty with the waterfall model has been its emphasis on fully elaborated documents as a completion criteria for early requirements and design phases. For some classes of software, such as compilers or secure operating systems, this is the most effective way to proceed. However, it does not work well for many classes of software, particularly interactive end-user applications.
Document driven standards have pushed many projects to write elaborate specifications of poorly understood user interfaces and decision support functions, followed by the design and development of large quantities of unusable code."


It is risky to treat software process improvements initiatives as just a punch of documents as Bohem stated above.
