What Can CodeWarrior Do?
When you realize that you can write better programs, you may no longer rely on applications developed by others. However, this often becomes a challenge when you're dealing with a large amount of code and struggling to find the specific line causing errors, making it impossible to compile or link your program. This situation can be very frustrating.
This article will guide you through using the CodeWarrior tool to solve these issues. From now on, we'll focus on programming in C/C++ using CodeWarrior. To take this course, you should already have some experience with either of these two languages. While CodeWarrior also supports Java development, that’s covered in another course. This one is specifically about developing on the Windows platform. Once you become proficient, you can explore using CodeWarrior on other platforms as well. Much of what we discuss here applies to Mac application development too.
CodeWarrior automatically identifies obvious errors in your code. It scans your code using an integrated debugger and editor to detect and reduce these errors, then compiles and links your program so that it can be executed by the computer. Every application you’ve used was coded, compiled, edited, linked, and debugged using a tool like CodeWarrior. Now, with our guidance, you can do the same. You can use CodeWarrior to create any type of program you can imagine. If you’re a beginner, you might start with an application, such as an executable like WordPad from Microsoft.
Applications are generally the easiest to develop, but even complex commercial software like Adobe Photoshop, Microsoft Word, and CodeWarrior itself are built using similar tools. Other types of programs include control panels, dynamic link libraries (DLLs), and plug-ins. Let’s briefly explore these.
In Windows, Control Panel programs are usually small applications stored in the Control Panel directory and accessible through the Start menu. These act as interfaces for system settings, such as adjusting volume or mouse sensitivity.
Dynamic Link Libraries (DLLs) provide shared functions used by both the system and applications. They typically don’t have a user interface.
Plug-ins are similar to DLLs but are designed to work with specific software. For example, Photoshop plugins allow developers to extend its functionality without modifying its source code. Many web browsers also use plugins to support new content types or add features. In fact, many programs, including CodeWarrior, use this plugin structure.
Once you understand how CodeWarrior interacts with your operating system, you’ll be able to create a wide range of programs. This course serves as a foundation for deeper programming studies. You've found one of the best starting points for your programming journey. So sit back, relax, and dive into this course — you're on your way to becoming a programming warrior!
CodeWarrior Overview
CodeWarrior is a powerful and complex application, and it's important to take time to understand its components and features. The first lesson will cover the installation of the CodeWarrior IDE. You’ll learn about menus, windows, and more. It’s recommended that you follow along with this course to get familiar with the CodeWarrior integrated development environment.
If you installed CodeWarrior by default, there should be a shortcut icon on your Windows desktop. Double-click it to launch the IDE. If not, you can find the IDE.exe file in `C:\Program Files\Metrowerks\CodeWarrior\Bin` and run it manually.
Toolbar
After launching CodeWarrior, you’ll see a toolbar at the top of the screen under the menu bar. This toolbar includes shortcuts for common menu items. In later chapters, you’ll learn how to customize this toolbar and the entire IDE environment. For now, remember that it helps you access key features quickly.
File Menu
The File menu handles file-related operations like creating, opening, saving, and printing files.
Edit Menu
The Edit menu offers standard editing functions like cut, copy, and paste, along with options for managing your code layout. It also includes a Preferences option, which we’ll revisit later.
View Menu
The View menu allows you to manage how toolbars and other windows are displayed. These windows include tools like Watchpoints, Expressions, Processes, and Global Variables.
Find Menu
The Find menu lets you search for specific code within files or directories. It’s useful for replacing text blocks or locating elements in your code.
Project Menu
The Project menu manages your projects, which consist of all the files needed for your program, including source code, header files, and libraries. We’ll go into more detail about this in Lesson 2.
Debug Menu
This is one of the most commonly used tools in programming. We’ll explore its full potential in Lesson 5.
Window Menu
This menu controls how windows are displayed within the CodeWarrior environment.
Help Menu
The Help menu provides online resources to answer any questions you may have about CodeWarrior.
Understanding the CodeWarrior IDE Settings
The CodeWarrior IDE offers several customization options to tailor your workspace. When you select "Preferences" from the Edit menu, you’ll see a settings dialog (Figure 1-3). This dialog includes options for customizing the editor, debugger, and other features. In this section, we’ll explore how to use these settings.
You can click the question mark next to each setting to get a brief explanation. You can also find more detailed information in the Help menu.
General Settings
- **Compile Settings**: Choose whether to save open files before compiling and how much memory to allocate for compilation.
- **IDE Extras**: Customize settings like using a third-party text editor instead of the built-in one.
- **Plugin Settings**: Useful for developers who want to test their plugins.
- **Hide Folders**: Specify folders to ignore during project builds or searches, especially if you have large data directories.
- **Source Trees**: Define directories that CodeWarrior doesn't need during compilation.
Editor Settings
- **Editor Settings**: Customize the appearance and behavior of the editor.
- **Font and Tabs**: Adjust font size, style, and tab settings.
- **Text Colors**: Define colors for different language elements, like comments or keywords.
Debugger Settings
- **Display Settings**: Customize how the debugger window looks.
- **Windowing**: Set how the debugger manages its windows.
- **Global Settings**: Configure how the debugger behaves globally, such as whether to start a program when a debugging file is opened.
- **Remote Connections**: Enable remote debugging over TCP/IP.
- **Java Settings/Java Debugging**: Configure Java-specific options (not covered here).
RAD Tool
- **Layout Editor**: Customize the rapid application development tools in CodeWarrior.
As you can see, CodeWarrior has a vast number of settings and options. After making changes, click “Save†to apply them. Click “Close†to discard changes. Practice a few times before moving on to the next lesson. Make sure the “Default Text File Format†in the editor settings remains set to DOS.
