Arnisoft

Pro

• Easy debugging and profiling
• Automatic adding of imports and organizing of imports
• Visual designer for MXML
• Because of Eclipse: support for other languages (eg. with Aptana, PDT…) and extendible with Eclipse plugins. So features like “Code Snippets” (CFEclipse), automatic code generation for Getter/Setter (Monkey Script) are usable
• Class Wizard
• Support for ASDoc comments
• Support for virtual folders/files (links to external files/folders handled intern by Eclipse, so also working on Windows)
• Refactoring (renaming of classes, functions, properties with automatic adaptation of dependencies)

Con

• Commercial license
• Plugin doesn’t work with all versions of Eclipse (eg. is not working with Eclipse Ganymede 3.4.1 or 64bit versions)
• Searching, adding and configuring the missing features with Eclipse plug-ins is often complex
• Code assist average and sometimes buggy eg. if correct imports are missing (“java.lang.NullPointerException”)
• No Code Formatter or automatic generation of getter/setter (only with Eclipse plugins like Monkey Scripts, CFeclipse, Flexformatter “FlexPrettyPrintCommand”...)
• No package explorer for SWC files

FlashDevelop

Pros

• Free and OpenSource (developed with C#)
• Lightweight
• Best available Code Assist for Actionscript
• Contextual code generation (getter/setter, variables, event handlers)
• Code Snippets
• Automatic adding of imports
• Extendible with plug-ins
• Support for ASDoc comments
• Package explorer (shows classes and symbols from SWC files)

Cons

• Only for Windows
• Plugins often not working in newer versions and many plug-ins are only rarely updated
• Debugging only with a plugin and more at an early stage
• No visual designer for MXML
• No class wizard
• No code formatter
• No support of virtual folders/files (“links”) insides the project
• No refactoring
