WUDSN IDE update 1.6.0 released

After 5 months I have completed a new major update of WUDSN IDE with a bunch a new features and improvements. Some of the new features like the graphics conversion and the content assist for identifier are still "beta" but already usable and useful. For example the syntax highlighting sometimes detects keywords within other words. This will be corrected soon.

Features: See the tab "Features" on WUDSN IDE for screen shots or click on the inline links

  • .ENUM and .STRUCT are now displayed as sections with own icons in the content outline
  • .VAR and .ZPVAR definitions are now displayed as equate definitions in the outline, they will get their own icon in the next version
  • .PROC, .LOCAL, .PAGES and binary includes now implicitly end a definition section even without ORG statement
  • The expanded nodes and the selected elements in the outline are now stable. In case of structural changes, the selection is repositioned automatically to the next higher visible parent element
  • The bold and italic style of the syntax highlighting is now also visualized directly in list within the preferences
  • Separately configurable syntax highlighting for all types of identifiers and numbers. For non unique identifiers, the syntax highlighting will try to be a best guess

  • Altirra is now available in the preferences as standard emulator for the Atari 8-bit editors
  • All editor names have been extended with the platform like "ACME (C64)"
  • The toolbar icon for "Compile and Run" now adapts based on the hardware of the currently opened editor, for example it will show a C64 icon when using the "ACME (C64)" editor
  • The toolbar icon for "Compile and Run" now has a pull down menu which allows running the output file with any of the applications configured in the preferences. This way you can run the output file easily with different emulators without changing the preferences. That can be very helpful if one emulator show a different behavior than another or in case you have specified a build script as user defined application in the preferences

  • MADS (Atari 8-bit) is the new default editor for the file extension ".asm" for new installations. You can change this as you desire in the preferences panel "General/Editors/File Associations"
  • Symbols file "*.lbl" is now only created if there are actually any symbols. An existing symbols file is deleted if it is empty
  • The graphics editor now supports viewing for all 23 Atari 8-bit image formats supported by version 1.0.1 of "FAIL (First Atari Image Library)" plus C64 charsets and sprites. This includes hires and multi color charsets, images with palettes and true color images.
