- termlib.js - JS-WebTerminal Object v1.66
-
- (c) Norbert Landsteiner 2003-2015
- mass:werk - media environments
- <http://www.masswerk.at/termlib/>
-
- Creates [multiple] Terminal instances.
-
- Synopsis:
-
- myTerminal = new Terminal(<config object>);
- myTerminal.open();
-
- <config object> overrides any values of object `TerminalDefaults'.
- individual values of `id' must be supplied for multiple terminals.
- `handler' specifies a function to be called for input handling.
- (see `Terminal.prototype.defaultHandler()' and documentation.)
-
- globals defined in this library:
- Terminal           (Terminal object)
- TerminalDefaults   (default configuration)
- termDefaultHandler (default command line handler)
- TermGlobals        (common vars and code for all instances)
- termKey            (named mappings for special keys)
- termDomKeyRef      (special key mapping for DOM constants)
-
- (please see the v. 1.4 history entry on these elements)
-
- required CSS classes for font definitions: ".term", ".termReverse".
-
- Compatibilty:
- Standard web browsers with a JavaScript implementation compliant to
- ECMA-262 2nd edition and support for the anonymous array and object
- constructs and the anonymous function construct in the form of
- "myfunc=function(x) {}" (c.f. ECMA-262 3rd edion for details).
- This comprises almost all current browsers but Konquerer (khtml) and
- versions of Apple Safari for Mac OS 10.0-10.28 (Safari 1.0) which
- lack support for keyboard events.
- v1.5: Dropped support of Netscape 4 (layers)
-
- License:
- This JavaScript-library is free.
- Include a visible backlink to <http://www.masswerk.at/termlib/> in the
- embedding web page or application.
- The library should always be accompanied by the 'readme.txt' and the
- sample HTML-documents.
-
- Any changes should be commented and must be reflected in `Terminal.version'
- in the format: "Version.Subversion (compatibility)".

- ### The sections above must not be removed. ###
-
- version 1.01: added Terminal.prototype.resizeTo(x,y)
- added Terminal.conf.fontClass (=> configureable class name)
- Terminal.prototype.open() now checks for element conf.termDiv
- in advance and returns success.
-
- version 1.02: added support for <TAB> and Euro sign
- (Terminal.conf.printTab, Terminal.conf.printEuro)
- and a method to evaluate printable chars:
- Terminal.prototype.isPrintable(keycode)
-
- version 1.03: added global keyboard locking (TermGlobals.keylock)
- modified Terminal.prototype.redraw for speed (use of locals)
-
- version 1.04: modified the key handler to fix a bug with MSIE5/Mac
- fixed a bug in TermGlobals.setVisible with older MSIE-alike
- browsers without DOM support.
-
- version 1.05: added config flag historyUnique.
-
- version 1.06: fixed CTRl+ALT (Windows alt gr) isn't CTRL any more
- fixed double backspace bug for Safari;
- added TermGlobals.setDisplay for setting style.display props
- termlib.js now outputs lower case html (xhtml compatibility)
-
- version 1.07: added method rebuild() to rebuild with new color settings.
-
- version 1.1:  fixed a bug in 'more' output mode (cursor could be hidden after
- quit)
- added socket-extension for server-client talk in a separate file
- -> "temlib_socket.js" (to be loaded after termlib.js)
- (this is a separate file because we break our compatibility
- guide lines with this IO/AJAX library.)
-
- version 1.2   added color support ("%[+-]c(<color>)" markup)
- moved paste support from sample file to lib
- * TermGlobals.insertText( <text>)
- * TermGlobals.importEachLine( <text> )
- * TermGlobals.importMultiLine( <text> )
-
- version 1.3   added word wrapping to write()
- * activate with myTerm.wrapOn()
- * deactivate with myTerm.wrapOff()
- use conf.wrapping (boolean) for a global setting
-
- version 1.4   Terminal is now an entirely self-contained object
- Global references to inner objects for backward compatipility:
- * TerminalDefaults   => Terminal.prototype.Defaults
- * termDefaultHandler => Terminal.prototype.defaultHandler
- * termKey            => Terminal.prototype.globals.termKey
- see also: Terminal.prototype.termKey
- * TermGlobals        => Terminal.prototype.globals
- * termDomKeyRef      => Terminal.prototype.globals.termDomKeyRef
-
- So in effect to outside scripts everything remains the same;
- no need to rewrite any existing scripts.
- You may now use "this.globals" inside any handlers
- to refer to the static global object (TermGlobals).
- You may also refer to key definitions as "this.termKey.*".
- (Please mind that "this.termKey" is a reference to the static object
- and not specific to the instance. A change to "this.termKey" will be
- by any other instances of Terminal too.)
-
- Added method TermGlobals.assignStyle() for custom styles & mark up.
-
- Unified the color mark up: You may now use color codes (decimal or hex)
- inside brackets. e.g.: %c(10)DARKRED%c() or %c(a)DARKRED%c()
-
- Added key repeat for remapped keys (cursor movements etc).
-
- version 1.41  fixed a bug in the word wrapping regarding write() output, when
- the cursor was set with cursorSet() before.
-
- version 1.42  fixed a bug which caused Opera to delete 2 chars at once.
- introduced property Terminal.isOpera (Boolean)
-
- version 1.43  enhanced the control handler so it also catches ESC if flag closeOnESC
- is set to false. fixed a bug with Safari which fired repeated events
- for the control handler for TAB if flag printTab was set to false.
-
- version 1.5   Changed the license.
- Dropped support for Netscape 4 (layers).
- HTML-elements are now created by document.createElement, if applicable.
- Included the formerly separate socket extension in the main library.
- Added methods 'backupScreen()' and 'restoreScreen()' to save a screen
- and restore it's content from backup. (see the globbing sample).
-
- version 1.51  Added basic support of ANSI-SGR-sequences.
-
- version 1.52  Added method swapBackup(), reorganized some of the accompanying files.
-
- version 1.54  Fixed BACK_SPACE for Chrome, DELETE for Safari/WebKit.
-
- version 1.55  Fixed dead keys issue for Mac OS (Leapard & later), vowels only.
- version 1.56  Fixed new ESC issue for Safari.
- version 1.57  Fixed dead keys fix: now only for Safari/Mac, German (de-de).
- version 1.59  Dropped dead keys fix, fixed backspace for Safari.
- version 1.6   Saved some bytes by discarding traces of ancient condition syntax
- Added input mode "fieldMode"
- version 1.61  Changes to defaults implementation of the constructor.
- version 1.62  Fixed a bug related to AltGr-sequences with IE8+.
- version 1.65  Added options for textColor and textBlur.
- version 1.66  textBlur accepts also an array of values for multiple text-shadows.
