Conventions

Lately, I've been trying to get started on porting Hula Hoop (an Android app based on the GDX game programming library and the Box2D physics library) to C/C++. Of course, it's of utmost importance to shave a few yaks before getting started.

First Steps

GNU/Linux is a software development environment in much the same way that git is a source code management tool: they're both of the "choose your own convention" variety so common in the Unix culture (linfo.org, joelonsoftware.com). Some things I've figured out so far:

  • If the app is going to be built for a variety of platforms, I'm going to need to build the dependecies for those platforms too. That means I don't want to depend on system-wide library installations, and

UTF is not a character encoding

[Unicode transformation formats (UTF)][utf] is not a character encoding. It is a family of mutually incompatible character encodings that are each capable of expressing the full range of possible Unicode characters.

Microsoft desktop applications that deal with plain text files, e.g. Notepad and Excel, use [UTF-16LE][utf16] under the name Unicode. Newer versions also offer UTF-16BE under the name Unicode big endian. An idiosyncrasy of Microsoft applications is that the character encoding of a plain text file is declared in a [byte order mark (BOM)][bom] at the beginning of the file. This works like magic in many cases, but results in a few garbled characters at the beginning of the file when the BOM is not respected as such.

While the preferred encoding for web applications these days is [UTF-8][utf8], not all platforms allow custom content to declare its character encoding. Even Microsoft's own IIS doesn't respect the [BOM][bom]. Plain text file formats like CSS and JavaScript that, unlike XML an

Dialogues don't have menu bars

A dialogue box doesn't have menu bars, tool bars, tool strips, ribbons, or status bars. A dialogue box has one or more buttons near the bottom. Clicking on a button that is labelled Ok, Cancel, Yes, or No normally closes the dialogue but this can sometimes be circumvented e.g. by an error about missing or malformed data, or by saying No in response to a subsequent dialogue that asks, "Are you sure?" Some authorities distinguish dialogue boxes from message boxes by the latter's inability to receive any user input beyond which button was pressed, but they are otherwise the same.

  • A dialogue box cannot be maximized or minimized.
  • Closing a dialogue box has the same effect as clicking its Cancel button if the dialogue box has a Cancel button, otherwise the No button. If a dialogue box has no such button, it should not be possible to close the dialogue box without clicking a button.
  • When the keyboard focus is on a dialogue box that has a Cancel button, pressing the Esc key is equivale
