Fully integrated assembler editor   » top

• The Eclipse platform contains editors like for example the generic text editor. Editors can support one or more content types identified by file extensions. One editor can be the default for a specific file extension. WUDSN IDE provides an assembler editor and a corresponding content type for every compiler. Every assembler editor has a default compiler associated which in turn defines via the preferences which application is used to run the output file.
  
• New content types and file associations for Atari 2600 compilers
  • DASM Source File (*.asm)
• New content types and file associations for Atari 8-bit compilers
  • ATASM Source File (*.asm)
  • MADS Source File (*.asm, default)
  • XASM Source File (*.asx, default)
• New content types and file associations for C64 compilers
  • ACME Source File (*.a, default)
• New content types and file associations for NES compilers
  • ASM6 Source File (*.asm)
• The default editor for an extension can be configured in section "File Associations" of the preferences with the button "Default"
  
• Syntax highlighting colors and styles for comments, directives, all types of identifiers, legal opcodes, illegal opcodes, pseudo opcodes, and strings
• Single line comments for the current line selection can be toggled using "CTRL-7" or the editor context menu entry "Toggle Comment"
• Configurable support for 16-bit opcodes of 65816
• Built-in support for ATASM assembler, MADS assembler, XASM assembler, ACME assembler
• Built-in support for running compiler output files with the operating system default application without configuration effort
• Built-in support for Altirra emulator, Atari800Win emulator, Atari800MacX emulator, Atari++ emulator
• Adding support for new compilers and application is possible via Eclipse extension points
  
• Compile or compile and run with a single keystroke or via the menu
• Toolbar button for "Compile and Run" which adapts to the hardware of the currently opened editor, for example, it will show a C64 icon when using the "ACME (C64)" editor
• The toolbar button for "Compile and Run" offers a pulldown menu that 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 shows different behavior than another or in case you have specified a build script as a user-defined application in the preferences
  
• Open source and output folder directly from the menu
• Open compiler help directly from the menu if the documentation is available in the default folder structure of the compiler executable
  
• Complete list of compiler error and warning messages in the problems view
• Direct navigation to the source location of the via double click on the problem message
• Problem markers in the scroll area including tooltip with problem message
  
• German localization for all Eclipse plugin texts. The original compiler messages are not translated but some are mapped automatically
  
  • ATASM ".bank" warnings are mapped to info messages
• Console view with original compiler output opens automatically in the background after compiling which useful in cases where the plugin is not yet complete. The "Compiler Console" is automatically brought to front when the compiler starts. This prevents the compiler output from being hidden behind other consoles in the console view
  

Content outline and source folding   » top

• Activated via the standard menu "Window/Show View/Outline"
• Automated asynchronous parsing while typing
• Automated recursive parsing of source includes and merge with the current outline
• Positioning in the content outline remains stable while typing unless structure changes appear
• Folding is activated automatically when the outline is visible
• Folding for if/else/endif blocks
• Outline and folding for definition section and implementation sections
• Outline for equate definitions (including defining expression), label definitions, and variable definitions
• Outline and folding for enum and struct definitions
• Outline and folding for macros definitions
• Outline and folding for repeat sections
• Outline and folding for procedure definitions
• Outline and folding for local sections
• Outline for source includes and binary includes
• Type-specific outline icons
• Nested folding with tooltip for folded sections
• Line end comment is used as a short description
• Toolbar with a button to toggle the sorting order of the sections and labels. The state of the button is persisted automatically along with the respective source file. For files that do not have a setting yet, the setting from the currently opened file will be used
  
  

Content assist and code completion   » top

• Content assist by pressing CTRL-Space for directives, legal opcode, illegal opcodes, and pseudo opcodes
• The content assist also recognizes if there is already an instruction in the current line and suggests the available identifiers instead if this is the case. This is the first version and it supports global identifiers in the current source file and source file included from there. Scoped identifiers of the form "a.b" are not yet supported
• Completion proposal auto-activation without pressing CTRL-Space after typing compiler dependent characters, for example "." in ATASM, "." or "#" in MADS and "!" in ACME
• Type-specific icon and mnemonic highlighting
• Progressive filtering as you type
• Automatic detection of lower case / upper case based on current input
• Default case configurable in preferences
• Illegal opcodes can be hidden via preferences
• 16-bit opcodes of 65816 can be hidden via preferences
  
• Multi-line content completion and explicit cursor positioning, for example ".MA" becomes ".MACRO <cursor is here> <newline> .ENDM"
  

Hyperlink navigation   » top

• Hyperlink navigation via CTRL-click to source includes and binary includes
• Support for relative and absolute file paths
• Source files are always opened with the same assembler editor, irrespective of the extension
• The ".asm" extension for "ICL" source includes is appended automatically in MADS, if it is missing
• The ".asx" extension for "ICL" source includes is appended automatically in XASM, if it is missing
• Option for binary includes for opening the file with
  • the built-in hex editor
  • the built-in graphics editor
  • the default Eclipse editor (e.g. a text editor)
  • system editor (e.g. an emulator or a paint program)
• Hyperlink navigation via CTRL-click to labels equates, local definitions, macro definitions, and procedure definitions. In case there is only one target, direct navigation takes place. In case there is more than one possible target, the type and line number of the target are displayed in a hyperlink popup. All included source files are also taken into account like in the content outline. In case there are targets from different files, the file name is also displayed as a differentiator in the hyperlink popup.
  
  
  
  

Hex Editor   » top

• Read-only hex editor to inspect arbitrary files
• Available via context menu including multi-file-selection to open several files at once
  
• The "Open With Hex Editor" menu entry closes an existing editor in case the file is already opened and thereby forces the file to be opened with the hex editor. In addition, the hex editor is set as the default editor for this file. As a consequence double-clicking the file in the package explorer will open it automatically with the hex editor, no matter which type of file is actually is. This saves you from always using the context menu, just because the file has no known file type. You can change the default editor again by just using the "Open With" context menu entry
• Available via hyperlink navigation for binary includes
• Context menu to copy parts of the file into the clipboard in different formats:
  • hex values (".byte $01,$02,...")
  • decimal values (".byte 1,2,...")
  • ASCII string
  This is very helpful to turn parts of a file into source code. The possibility to copy/paste into the binary file itself in order to modify is prepared but not working yet and will be completed later.
  
• Support for binary files, Atari COM files, and Atari Disk Images
  
• The possible file modes for a binary file are computed automatically and used as default when opening the file
• Unsupported file modes are detected and cannot be used
• Files with a block structure get an outline in the outline view
• Files with a corrupted block structure are detected and displayed as good as possible
  
  

Graphics Editor   »

• Viewer for binary files and 8-bit image files.
  The most suitable supported converter and the corresponding default parameters are computed based on the file content, size, and extension.
  The converters for the Atari standard image formats are based on RECOIL fka. FAIL, the excellent First Atari Image Library created by Piotr Fusik and Adrian Matoga.

• Viewer for GIF/JPG/BMP/PNG images
• Available via context menu including multi-file-selection to open several files at once
  
• The "Open With Graphics Editor" menu entry closes an existing editor in case the file is already opened and thereby forces the file to be opened with the graphics editor. In addition, the graphics editor is set as the default editor for this file. As a consequence double-clicking the file in the package explorer will open it automatically with the graphics editor, no matter which type of file it actually is. This saves you from always using the context menu, just because the file has no known file type. You can change the default editor again by just using the "Open With" context menu entry
• Available via hyperlink navigation for binary includes
• Conversion from binary files or 8-bit images files to GIF/JPG/BMP/PNG images
  • Up to different 3 source files depending on the converter
  • Configurable start offset for every source file, useful for extracting character sets
  • Configurable palette via the Image Palette view
  • Configurable number of rows and columns
  • Configurable spacing width for and spacing color to separate tiles and unused areas

  • Separate aspect ratio for loading and displaying the image file
  • Default scripts are included. They can be adjusted and saved along with the other parameters
  
  
• The image palette view associated with the graphics editor displays the palette entries and the color histogram. It supports filtering of unused colors, sorting by index and color frequencies, pre-settings, and editing the palette when displaying 8-bit images
  
• Conversion files with extension ".cnv" are used to save the conversion direction and all conversion parameters
• Support for relative file paths. If the file path is in the same folder as the ".cnv" file, it is automatically converted to a relative file path when the file name is defaulted or picked from the file browser dialog. This allows to move the ".cnv" file and the referenced source files around together without breaking the saved paths

Annotations for compiling   » top

• For most use-cases, the defaults provided for the compilers and in the preferences are sufficient. But if you want to develop in parallel in multiple projects, for different platforms (Apple II and Atari 8-bit) or in different output formats (".XEX" and ".BIN") with the same compiler it may become cumbersome to change the preferences every time. Therefore WUDSN IDE offers annotations that you can put into the source code files. These annotations override the defaults and the preferences.
• All annotations start with the prefix "@com.wudsn.ide.asm." followed by the lower case name of the annotation, an equals sign, and the unquoted value. Example: "@com.wudsn.ide.asm.hardware=ATARI8BIT"
• All annotations can be placed in comment lines at the beginning of a source file. Some of the annotations are only relevant for the main source file, some are only relevant in include source files, some are relevant for all source files.
• @com.wudsn.ide.asm.hardware
  • Defines the target hardware for which the preferences shall be evaluated, in particular, which emulator is used to run the output file.
  • Allowed values are "APPLE2", "ATARI2600", "ATARI7800", "ATARI8BIT", "C64", "NES".
  • This annotation is relevant for all source files.
  • This annotation is only evaluated when a file is opened. So if you add this annotation or change its value, you have to close and re-open the file once.
  • Example: @com.wudsn.ide.asm.hardware=ATARI8BIT
• @com.wudsn.ide.asm.mainsourcefile
  • Defines the main source file to which the current include source file belongs. When the "Compile" action is executed, the main source file is compiler instead of the current file.
  • Allowed values are file paths relative to the folder of the current include source file and absolute file paths.
  • This annotation is only relevant in include source files.
  • Example: @com.wudsn.ide.asm.mainsourcefile=ExampleMain.asm
• @com.wudsn.ide.asm.outputfoldermode (planned for 1.7.0)
  • Overrides the "Output Folder Mode" from the preferences.
  • Allowed values are "SOURCE_FOLDER", "TEMP_FOLDER", "FIXED_FOLDER".
  • This annotation is only relevant in the main source file.
  • Example: @com.wudsn.ide.asm.outputfoldermode=SOURCE_FOLDER
• @com.wudsn.ide.asm.outputfolder (planned for 1.7.0)
  • Overrides the "Output Folder" from the preferences and the "@com.wudsn.ide.asm.outputfoldermode" annotation.
  • Allowed values are file paths relative to the folder of the main source file and absolute file paths.
  • This annotation is only relevant in the main source file.
  • Example: @com.wudsn.ide.asm.outputfolder=..\out
• @com.wudsn.ide.asm.outputfileextension (planned for 1.7.0)
  • Overrides the "Output File Extension" from the preferences.
  • Allowed values have to start with a period.
  • This annotation is only relevant in the main source file.
  • Example: @com.wudsn.ide.asm.outputfileextension=.bin
• @com.wudsn.ide.asm.outputfile (planned for 1.7.0)
  • Overrides the "Output Folder", "Output File Extension" from the preferences and the automatic computation of the out file name based on the main source file name.
  • Allowed values are file paths relative to the folder of the main source file and absolute file paths.
  • This annotation is only relevant in the main source file.
  • Example: @com.wudsn.ide.asm.outputfile=..\out\output.bin
