- What's New:
- ───────────
- This file briefly highlights some of the new features available in
- Aurora version 2.1. For more detailed information, see the User's Guide,
- the AML Language Reference, and the AML Function Reference.
-
-
- Aurora version 2.1
- ──────────────────
- * Aurora now features a new 'Interactive Configuration', in addition to
- the standard .AML configuration files. Dialog boxes have been provided
- for changing most configuration settings interactively within an edit
- session. The new configuration dialog boxes are accessible through the
- 'Configuration and Setup' item on the 'Set' menu. Interactive
- configuration settings include:
-
- - Colors - Open Options
- - Confirmations - Print Options
- - Desktop Options - Prompt Styles
- - Edit Options - Save Options
- - File Manager Options - Sort Options
- - Line Delimiters - Search / Replace Options
- - Margins and Tabs - Text Reformatting Options
- - Miscellaneous Options - Video Modes
- - Mouse Options - Window Styles
-
- * The 'Save Configuration' item on the Set menu will now directly update
- source CONFIG.AML and COLOR.AML files with the current configuration
- settings and recompile the editor. Unlike v2.0, changes will not be
- lost when you recompile the editor.
-
- * Source code for the new configuration dialog boxes is located in a new
- 'CFG' subdirectory, making even the configuration scheme configurable!
- Within this code, custom dialog boxes are created by using new library
- functions (see below). The installation macro (INSTALL.AML) was also
- modified to accomodate the new CFG subdirectory.
-
- * The following new AML macros have been added to the macro list (on the
- Macro menu), and to the MACRO subdirectory:
-
- ASCII2.AML - 2-dimensional ASCII chart
- BOOKLIST.AML - List all bookmarks
- CALEN4.AML - Four-month calendar
- COMPARE.AML - Compare two files
- COUNTLIN.AML - Count lines in multiple files
- DLGDEMO.AML - AML dialog box demo with dialog box controls
- SCRSAVER.AML - AML Screen Saver demo showing how to draw on the screen
- STYLE.AML - Change the editor keyboard/menu style
- TEMPLATE.AML - Install Template-Editing
- TEMPLATE.DAT - Template data (used by TEMPLATE.AML)
-
- * The macro list can now be displayed by pressing <ctrl f12>
-
- * Several macros have been rewritten. These macros now take advantage of
- important new macro language features which allow them to run as
- independent, movable, switchable, windows (you can also run multiple
- instances of these macros). The rewritten macros include:
-
- ASCII2.AML - 2-dimensional ASCII chart
- KEYCODES.AML - Display various keycodes
- CALCPAD.AML - Calculator pad
- CLRCHART.AML - Color chart
- CALENDAR.AML - One-month Calendar
- CALEN4.AML - Four-month Calendar
-
- * A following new keyboard/menu styles are available at installation.
-
- - Aurora/CUA/Windows
- - MultiEdit
-
- * Commands were added to the clipboard menu which allow you to 'Copy To'
- and 'Paste From' the Windows Clipboard (up to 16k bytes). Aurora must
- be running in an MS Windows/95 DOS box or an MS Windows 3.1 enhanced
- mode DOS box to use these commands.
-
- * The following additional changes were made to the default menus:
-
- Window menu:
- - removed "Style Toggle" (equivalent function is now provided
- from within the 'Configuration and Setup' menu item)
-
- Set menu:
- - added 'Configuration and Setup'
- - 'Word Processing' was relaced with 'Margins and Tabs'
- - 'Binary Line Length' and 'Line Delimiter Options' were replaced
- - with 'Line Delimiter Options'.
- - 'Video Mode' and 'Video Toggle' were removed (equivalent
- function is now provided from within the 'Configuration and
- Setup' menu item)
-
- Macro menu:
- - added 'Show Available Keys..'
- - removed 'Configuration..'
- - removed 'Include Macro'
-
- * The new '>' and '<' window style option codes will now allow Edit and
- File Manager titles to be placed within the window border, when the
- border style is not zero. These options can also be changed from the
- 'Window Style 1' configuration dialog box.
-
- * All online documentation is now 'read/only' when opened through the
- help menus and hotkeys.
-
- * A new "Sort Options" dialog box is displayed when entering the
- 'sortblock2' (Block Sort) command.
-
- * The File Manager will now always show the drive bar, even if the menu
- bar is removed.
-
- * Hot key positioning on the File Manager and Popup Menus will now use
- incremental searching.
-
- * New listbox color attributes (71-74) were added to COLOR.AML.
-
- * The following changes were made to CONFIG.AML:
-
- - Added the new setting 'FormatOpt', for default text reformatting
- options.
-
- - Added the new setting 'SortOpt', for default block sorting
- options.
-
- - The 'FmgrCtls' and 'EditCtls' settings were removed. South title
- controls are now defined by adding style option 'z' to 'EditStyle'
- and/or 'FmgrStyle'.
-
- - 'ExitOpen' was moved to the Desktop section.
-
- * Several changes were made to the keyboard configuration and handling:
-
- - In SYSTEM.AML, the new 'kbdoptions' setting replaces the
- 'enchancedkbd' setting. The new keyboard options are:
-
- e = enable enhanced keyboard keys
- g = enable unshifted grey keypad function keys
- (<grey*>, <grey->, <grey+>)
- w = enable shifted white keypad function keys
- (<shift del>, <shift ins>, <shift end>, etc.)
-
- (numeric keypad users may wish to disable options 'g' and/or 'w')
-
- - The shifted grey island keys (<shift del>, <shift ins>, etc.) are
- now handled properly, and are no longer interpreted as <del>,
- <ins>, etc. The keyboard configuration files for all editor styles
- were modified to reflect these changes.
-
-
-
- Macro Language Additions/Changes in version 2.1:
- ────────────────────────────────────────────────
-
- Architectural Changes:
- ──────────────────────
-
- * Global variables are now 'persistent', and will hold their values
- throughout the lifetime of the macro in which they are defined. When
- used within internal macro areas such as KBD.AML, EXT.AML, etc.,
- global variables will hold their values throughout an entire editing
- session.
-
- * The 'runmacro' function will now allow pre-existing functions to be
- replaced or 'preempted' throughout the lifetime of the external macro.
- This is accomplished by simply defining a function with the same name
- as the function to be preempted, in the same object as the function to
- be preempted.
-
- This feature allows detailed, temporary modifications to be made to
- existing objects (i.e. detailed changes in editor behavior), without
- adding new objects to the object hierarchy. The modifications will
- disappear when the macro is finished executing, or the temporary
- object associated with 'runmacro' is destroyed.
-
- The new function 'passprev' can be used within the newer preempting
- functions to access the older preempted functions.
-
- * The new 'stayresident' function allows external macros executed by
- 'runmacro' to remain resident after they are finished executing,
- similar to way the 'includemacro' function works. Functions can be
- defined within the macro which respond to events after 'runmacro'
- returns.
-
- However, unlike macros executed with 'includemacro', these new
- resident macros can also be 'purged' by destroying the temporary
- object automatically created by 'runmacro'.
-
- Using the 'stayresident' function, it is possible to write Aurora
- mini-applications which behave as independent windows on the desktop.
- Macros such as CALCPAD, CALENDAR, CLRCHART, etc. are examples of these
- mini-applications.
-
-
- Syntax/Compiler Changes:
- ────────────────────────
-
- * Objects and functions may now have the same name.
-
- * The 'object' statement is no longer permitted within functions or key
- definitions.
-
- * A new compiler error code (1318: invalid number) was added.
-
- * The following standard backslash control characters can now be entered
- within strings:
-
- \a - alert (beep) character (ASCII 7)
- \b - backspace character (ASCII 8)
- \f - formfeed character (ASCII 12)
- \n - newline (linefeed) character (ASCII 10)
- \r - return character (ASCII 13)
- \t - tab character (ASCII 9)
- \v - vertical tab character (ASCII 11)
- \xHH - any hex character
-
- * The following new keywords can now be used instead of the 'end'
- keyword, in their respective language structures:
-
- endcase endkey
- enddatabuf endloop
- enddefine endmenu
- endfunction endmenubar
- endif endwhile
-
- * The AML compiler generates smaller executable code (A.X in v2.1 is
- about 5k smaller than A.X in v2.0).
-
-
- Function Additions/Changes:
- ───────────────────────────
-
- * A new dialog box interface is now provided by the editor library code
- (LIB.X), enabling you to create custom dialog boxes - see FUNCTION.DOX
- and LANGUAGE.DOX for full details. For examples on how to create and
- use dialog boxes, see the dialog box demo DLGDEMO.AML, and macros in
- the new CFG subdirectory. The new dialog box functions are:
-
- dialog - creates a main dialog box window
- button - creates a button control
- field - creates an edit field control
- listbox - creates a listbox control
- groupbox - creates a groupbox control with checkboxes or
- radio buttons
- setgroupbox - re-initializes a groupbox
- getdialog - displays a 'modal' dialog box, and retreives
- dialog box control values.
- showdialog - displays a 'modeless' dialog box.
- whenenter - defines a user-function to be called when <enter>
- (or equivalent) is pressed from within a dialog
- box control.
- whenselect - defines a user-function to be called when an item
- is selected from within a group box or list box.
-
-
- * The following new functions were also added (see FUNCTION.DOX for full
- details):
-
- builtin functions:
- fillrect // fill a rectangle with a character
- getattr // get a color attribute from a video window
- geteventcount // get the number of real events
- getstr // get a string from a video window
- gotoscreen // route video functions to the physical screen
- inheritfrom // change the inheritance path of the current object
- kbdoptions // set keyboard options
- parse // parse substrings of a string into variables
- passprev // call the current function in a preempted object
- stayresident // force an executable macro to remain resident
- windowflag // change window flags
-
- comments:
- - gotoscreen enables video functions such as writestr, hilite,
- etc. to write directly to the physical screen.
-
- - parse will extract substrings of a string and place them in
- user variables, with only one function call. The substrings
- are specified with a search pattern, which may be a regular
- expression pattern. This function is very handy for parsing
- almost anything, including compiler output.
-
- - windowflag enables the new events 'ondraw' and 'onstatus' (see
- below), which allow customized drawing of the window and
- status line.
-
-
- library functions:
- askbox // prompt the user for a string (2-line box)
- askbox1 // prompt the user for a string (1-line box)
- askline // prompt the user for a string (command-line prompt)
- enter // enter key (prompt object)
- setmenucurs // change menu cursor style
-
- extension functions:
- runcfg // run a macro in the CFG subdirectory (w/prefix CFG)
- runmac // run a macro in the MACRO subdirectory
- savecfg // save current config variables and recompile
-
- events:
- ondraw // called after drawing the window client area
- onkillfocus // called before before a window loses the focus
- onstatus // called before drawing the window status line
-
-
- * The following functions were removed:
-
- builtin functions:
- enhancedkbd // replaced by: kbdoptions
- getobjsize // not needed
- clearwindow // not needed: the same effect can be achieved with
- 'hilite' and the new 'fillrect' function
-
- library functions:
- togglestyle // replaced by: runcfg "style"
-
- extension functions:
- saveconfig // replaced by: savecfg
- includemacro2 // seldom used
- askimacro // seldom used
- askbinary // replaced by: runcfg "ldlm"
- askdelim // replaced by: runcfg "ldlm"
- asktabw // replaced by: runcfg "marg"
- asktabv // replaced by: runcfg "marg"
- asklmarg // replaced by: runcfg "marg"
- askrmarg // replaced by: runcfg "marg"
- askprint // replaced by: runcfg "print"
- askprompt // replaced by: runcfg "prom"
-
-
- * The following functions were altered in some way:
-
- builtin functions:
- -----------------
- bufferflag, bufferflag?
- Option 'r' was added to these functions to permit buffers to be
- made 'read-only'.
-
- gotobuf
- gotobuf now returns the previous current buffer.
-
- gotowindow
- gotowindow now returns the previous current window.
-
- hilite
- hilite now advances the cursor in video windows if the height is
- one.
-
- menubar, getmenubar
- Removed the west menubar (menubar 5).
-
- replace
- When using regular expressions, any of the special control
- characters "\a\b\f\n\r\t\v\xHH" can be used in the replace
- string.
-
- say
- say is now a builtin function, and works in any window.
-
- setdisplay
- Added the display option -1, which validates the display so that
- updating will not be performed. This allows you to draw in an
- edit window without the editor immediately overwriting it.
-
- setframe, frame?
- Added new option codes '>' and '<' for north and south
- title-in-border frame options.
-
- usemark
- usemark now returns the previous default markid.
-
-
- library functions:
- -----------------
- msgbox, okbox, shortbox, yncbox
- These functions will now allow message boxes with 2 message
- lines to be displayed when a newline character (\n) is inserted
- in the message string.
-
-
- extension functions:
- -------------------
- ask
- ask is no longer a library function, but is now exposed in
- EXT.AML, allowing you to customize the dialog box appearance
- when using the dialog box prompt style.
-
- onhotkey
- onhotkey now works with any number of leading spaces on popup
- menu items (onhotkey now works correctly on help popup menus).
-
- saveblock2
- Added a new parameter: the filename where the block should be
- saved. You are prompted if the filename is not specified.
-
- writebak
- writebak is no longer a builtin function, but is now exposed in
- EXT.AML. Parameter order has also been changed to resemble the
- 'writestr' builtin function.
-
