==============================================================================
= Alpha Commands
==============================================================================

In this list of routines, text between '<' and '>' is a placeholder for a
required parameter, text between '[' and ']' is a placeholder for an
optional parameter, and the '|' signifies a choice of two or more
alternatives.  A '+' signifies that the previous symbol can be present one
or more times, while a '*" means zero or more times.  Some commands have no
parameters, and are only expected to be called interactively.



The following are Alpha-specific tcl routines:

• abortEm - aborts whatever is currently happening
• abbrev <label> <string> [<mode>] - register a label for <string>. See
'execAbbrev'.
• addAlphaChars <chars> - Add <chars> to the list of characters that internally
  are caught by the 'isalnum' and 'isalpha' calls. Can be used to augment
  the list of characters that the \w pattern in a regular expression
  responds to. Use w/ care.
• addMenuItem [-m] [-l <meta-characters>] <menu name> <item name> - Convert
  item to menu form and add to specified menu. If '-m' specified, menu
  form conversion not done. The '-l' option allows you to use menu meta
  characters as text of menu items. If the '-l' option is used, the
  <meta-characters> string is interpreted for menu item attributes, and
  meta-characters in <item name> are included in the menu item text
  literally. For example:
      addMenuItem -m -l "/B" "Hello/C"
  would appear as the text "Hello/C" in the menu, and have "B" as its
  command equivalent.
• addDef <var> <val> - Permanently save an association between the var
  'var' and 'val'. 'addDef' and 'addArrDef' are now the sanctioned way to
  save values between sessions. Also see 'removeDef' and 'removeArrDef'.
• addArrDef <var> <field> <val> - Permanently save an association between
  the var var(field) and 'val'.
• AEBuild [<flags>] <app (name|creator)> <aesuite> <aeevent> [<event parameters>]*  -
  Build and send an apple-event. 'AEBuild' is apple's code of the same
  name. Each "event parameter" is two parameters, a parameter type and
  the data for the parameter. See the AEBuild doc for more details,
  :Tcl:SystemCode:think.tcl for examples. The flags are '-r' (wait for reply),
  '-q' (queue reply, in which case 'handleReply' (in appleEvents.tcl) is
  called with the reply as a parameter, and '-t <timeout>' specifies the
  timeout in ticks.
• alertnote message_string
  This command will display message_string in a standard Macintosh alert box.
• alphaHelp - display Alpha help.
• ascii (see bindings).
• askyesno [-c] prompt
  This command will display a Macintosh alert box with 'prompt' displayed
  with the push buttons Yes and No. The command will return the
  string "yes" or "no". The '-c' flag specifies that a cancel button be
  used as well.
• backColor - set background color
• backSpace - delete selection, or a single char if no selection.
• backwardChar - moves insertion one char back
• backwardCharSelect - extends selection one char back
• backwardDeleteWord - deletes previous word
• backwardWord - moves insertion one word back
• balance - selects smallest set of parens, braces, or
  brackets that encloses the current selection
• beep
• beginningBufferSelect - extend selection to the
  beginning of the buffer
• beginningLineSelect - extend selection to the
  beginning of the line
• beginningOfBuffer - move insertion to the beginning
  of the buffer
• beginningOfLine - move insertion to the beginning of
  the line
• bind  (see bindings)
• blink <pos> - blink cursor at 'pos'
• breakIntoLines <string> - return 'string' with
  carriage returns and spaces inserted to satisfy
  'leftFillColumn' and 'fillColumn' variables.
• bringToFront <winName> - Bring named window to front.
• buttonAlert <prompt> [<button>…] - Create a dialog w/ the specified
  buttons, returning the one selected.
• capitalizeRegion - capitalize all words in selected
  region
• capitalizeWord - capitalize word
• centerRedraw - redraw window with current line in
  the middle.
• clear - clear selected text
• closeAll - close all windows
• colors <fore red> <fore green> <fore blue> <back red> <back green> <back blue>
• colorTriple [<prompt>] [<red> <green> <blue>] - Prompts user to choose
  color. If specified, the input RGB value is used as the initial color on
  the colorpicker.
• copy - copy region
• cp <fromName>+ <toName>
  This command will copy the file fromName and name the new file toName,
  overwriting any existing file. This command copies both data forks, and
  the Finder information.
• createTagFile - searches all files in current file set
  and saves the locations of any function declarations
  in a file called 'cTAGS'.
• createTMark <name> <pos> - create a temporary 'mark'
  at location 'pos'.
• currentPosition - displays current and total bytes.
• cut - deletes and saves region
• decToHex - convert decimal number to hex.
• deleteChar - delete char AFTER cursor
• deleteMenuItem [-m] <menu name> <item name> - Convert item to menu form
  and delete from specified menu. If '-m' specified, menu form conversion
  not done.
• deleteModeBindings <mode> - Delete all bindings for specified mode.
• deleteSelection - delete current position, don't save
• deleteWord - delete word after cursor
• describeBinding - display the binding of the next typed key sequence.
• deleteText <pos1> <pos2> - remove text between 'pos1'
  and 'pos2'
• dialog [<-w width>|<-h height>|<-b title l t r b>|<-c title val l t r b>|
            <-t text l t r b>|<-e text l t r b>|<-r text val l t r b>|
            <-p l t r b>]+
  Create and display a dialog.  '-w' and '-h' allow width and height of
  dialog window to be set.  '-b', '-c', '-r', '-t', '-e' and '-p' allow
  buttons, checkboxes, radio buttons, static text, editable text and gray
  outlines to be created, respectively.  All control types (except gray
  outlines) require specification of a title or text, together with left,
  top, right, and bottom coordinates.  Checkboxes and radioboxes have an
  additional parameter, the default value.  At least one button must be
  specified.  The return value is a list containing resulting values for
  all buttons, radioboxes, checkboxes, and editable textboxes (static text
  is ignored).  Buttons have value '1' if chosen, '0' otherwise.  The
  dialog box exits at the first button press.

• dirs - show current directory stack. See 'pushd' and 'popd'.
• display [-w <win>] <pos> - move pos's line to top of screen.
• displayMode <mode> - Up to four characters of the 'mode' string are
  displayed in the status line at the bottom of a window.
• dosc [<-c 'sign' | -n appName>] [-k 'clas'] [-e 'evnt'] <-s string | -f fileName> [<-t timeout|-r>]
  Send an AppleEvent, by default class 'misc', event 'dosc'.
   -c 'sign'
           "sign" is a four-letter creator signature of a running application.
   -n appName
           "appName" is the name of a running application.
   -k 'clas'
           "clas" is a four-letter event class.
   -e 'evnt'
           "evnt" is a four-letter event class.
   -s string
           "string" is the text of a script to send to the other app.
   -f fileName
           "fileName" is the complete or relative pathname of a file the other
           application should execute.
   -t timeout
           "timeout" is the number of ticks Alpha should wait for a response. A
           timeout of "0" means wait forever.
   -r
           Do not wait for reply.
   -q
           Queue reply.

   If neither of the '-c' and '-n' options is chosen, the PPC Browser is
   used. Either '-s' or '-f' must be chosen. Thus, you can have "Alpha
   5.02" and "Alpha 5.02 Copy" sending Apple events to each other, or they
   can send events to a remote server such as Apple's ToolServer.
   "$HOME:Tcl:UserCode:createStuffitArchive.tcl" contains examples of
   controlling Stuffit Deluxe via this command.

  definition
• float -m <menu> [<-h|-w|-l|-t|-M> <val>] [-n winname] [-z tag] -
  Takes a created menu (not necessarily in the menubar), and makes a
  floating window out of it. Returns integer tag that is used to remove
  the window. NOT DYNAMIC!  W/ no options returns all currently defined menus.
  Displayed w/ system floating window WDEF if system 7.5, plainDBox

• getAscii - displays the ASCII code for character at
  current insertion point
• getChar - waits for a keystroke, returns ascii.
• getModifiers - returns current modifiers mask. "OR" of several values,
    cmdKey                        = 0x01,                        /* Bit 0 of high byte */
    shiftKey                    = 0x02,                        /* Bit 1 of high byte */

    rightControlKey                = 0x80,                        /* Bit 7 of high byte */
• getColors - returns list of colors/hypertext for current document.
  Format is list of lists, each sublist consisting of file offset, color
  index, and possibly a hypertext command.
• getfile [<prompt>] [<path>]
  This command will display an SFGetFile() and return the full path name of the
  selected file, or an error if CANCEL button was selected.  An optional path
  parameter specifies a default directory or file.
• getFileInfo <file> <arr> - Given a file name, creates an array called
  'arr' in the current context, containing fields 'created', 'creator',
  'modified', 'type', 'datalen', and 'resourcelen'. 'created' and
  'modified' are in a form suitable for the command 'mtime'.
• getGeometry [win] - return a TCL list containing the left
  edge of the current window, the top, the width, and height.
• getline <prompt> <default>
  This command will display a Macintosh alert box with prompt displayed, a
  text edit field with default initially in the field, and with the push
  buttons OK, Cancel.. The command will return the text entered into the
  text edit field by the user, or an empty string if the user selected the
  Cancel button.
• getMainDevice - return a list containing the left, top, right, and
  bottom of the rectangle defining the main device.
• getMark - return the current mark.
• getNamedMarks [-w <win>] [-n] -
  return list of all permanent marks in open files. Each
  element of a list describes one mark as a sublist of the mark's name,
  the complete pathname of the mark's file, the position of the first
  character in the first line displayed, the current position, and the
  end of the selection if text is hilited, or the current position again
  if there is no hilited section. '-w' allows window name to be applied
  as filter, '-n' means only names will be returned.
• getPathName - prompt the user with an SFGetFile dialog and return
  complete pathname.
• getPos [-w <win>] - return the current insertion point
• getScrap - returns system TEXT scrap.
• getSelect - return the currently selected text, if
  any.
• getText [-w <win>] <pos1> <pos2> - return the text between 'pos1'
  and 'pos2'. '-w' can be used to specify a window.
• getTMarks - Return a list of temporary marks. Each item of the returned
  list is a sublist containing the mark name, the complete pathname of the
  mark, and the start and finish of the selection named by the mark. The
  following is an example of the result:

    {{temp1 External:file.c 1312 1315} {temp2 Internal:it.h 111 111}}

• getWinInfo [-w <win>] <arr> - Creates an array in current context
  containing info about either the current or a specified window. Array
  has fields 'state', 'platform', 'read-only', 'tabsize', 'split',
  'linesdisp' (num lines that can be seen in the window), 'currline'
  (first line displayed), and 'dirty'.
• glob [-i] [-t <TYPE>] [-c <CRTR>]
  The original glob provided by the UNIX version of tcl was not quite
  adequate for the more complex Macintosh file system. Issues such as
  invisible file handling, Finder type and creator filtering, and space
  handling in file names. Release 6 of tcl has dealt with the original
  problem with spaces in filenames, but the following options are provided
  to deal with additional Macintosh issues.

Anyway, the new glob now takes several options. They are:
    -i    This option causes glob to list invisible files also.
    -t TYPE    This option causes glob to only list file with the
        indicated Finder file typeTYPE. This option may be
        used with the -c option.
    -c CRTR    This option causes glob to only list file with the
        indicated Finder file creatorCRTR. This option may
        be used with the -t option.
        Also note that the original glob would skip dot files
        (i.e., file names the begin with a period)
        in the listing, unless the pattern began with a period.
        Tickle extends this concept one step further on the
        Macintosh, and skips spot files (i.e., file names that
        begin with '•'), unless the pattern starts with a spot.
• goto <pos> - goto the position 'pos'.
• gotoMark - goto named mark, use 'mark' in macros.
• gotoTMark <name> - goto the temporary mark 'name'.
• hexToDec <num> - hex to decimal conversion.
• icon [-f <winName>] [-c|-o|-t|-q] [-g <h> <v>] - Having to do w/
  iconifying windows. '-c' means close (iconify) window, '-o' open, '-t'
  toggle open/close, '-q' returns either a '1' for an iconified window or a
  '0' for an uniconified window, and '-g' moves the icon to horizontal
  position <h> and vertical position 'v'. Options are executed as they
  are parsed, so the '-f' option, if present, should always be first.
• icURL <URL> - passes arg to Internet Config, if present. Error if not
  present.
• icGetPref [<-t <type>] <pref name> - Gets preference from
  Internet Config. '-t' allows type to be set, '0' returns a string
  (default), '1' returns a path name, commonly used for helper apps. A
  <pref name> of 'all' returns all valid preferences.
• icOpen - Opens Internet Config
• insertAscii - prompts for an ASCII code and inserts
  into text.
• insertColorEscape <pos> <color ind> [hypertext func] - Create a color
  or style "point" for documentation purposes. Look at the file
  "docColors.tcl" for examples. The hypertext func is only used when the
  "point" is underline. See 'getColors' for info about the current file.
• insertFile - prompts for a file name and inserts the
  corresponding file into the current window. Not
  undoable.
• insertMenu <name> - insert the previously created user menu 'name' into
  the menuBar.
• insertPathName - present the user w/ a SFGetFIle dialog
  and paste the complete path-name of the chosen file
  into the current window
• insertText [-w <win name>] <text>* - Insert 'text' at the current
  insertion point. Mark is unchanged.
• insertToTop - make the line that the insertion point
  is on the first line shown, and display the current
  line number along w/ the total number of lines in file
• isearch - incremental search: searches w/o a dialog,
  searches as you type the search pattern. Does not do
  regular expression searches. 'matchWords'
  automatically set to false.
• iterationCount - allows actions to be repeated many times. "control-u 44
  =" inserts 44 '='s into current window.  Also can be used to execute any
  function or macro (including the keyboard macro) many times.  Defaults to
  4.
• jumpToRegister - prompts for a single char, and then jumpts to
  temporary mark of that name created by 'pointToRegister'.
• keyAscii - insert ascii representation (in decimal)
  of the keydown event, plus a modifier string, if
  necessary.
• keyCode - insert the key code along w/ a string
  representing and modifiers into the current window.
  Can be used to create bindings in 'Alphabits'.
• killLine - kill text from insertion point to the end
  of the line. If the line has no text, delete the line
  and move succeeding lines up one.
• killWindow - kill current window
• largestPrefix <list> - Returns the longest prefix contained in all
  strings of 'list'.
• launch -f <name> - launch the named app into the background. Note that
  for some yet unexplained reason, some applications (MicroSoft Word)
  won't launch completely in the background. 'launch'ing such
  applications won't insert the application into any system menu that
  specifies running applications (although "About the Finder..." will
  list it. The only way to get to such an app is through Alpha's
  'switchTo', after which the application will finish launching. The '-f'
  option gets around this by launching the application in the foreground
  instead.
• lineStart <pos> - return the position of the start of
  the line 'pos' is on.
• listBindings - list all current bindings.
• listpick [-p <prompt>] [-l] [-L <def list>] <list>
  This command will display a dialog with the list displayed in a List Manager
  list. If the user presses the Cancel button, an empty string is returned. If
  the user selects the Open button, or double clicks an item in the list, that
  item will be returned. If '-l' is specified, than the return is a list of
  items.
• load - loads hilited text, or entire window if
  nothing is hilited. 'load'ing means that whatever
  bindings or macro definitions are present in the
  loaded text take effect
• lookAt [-w <name>] <pos> - return the 'pos'th character of the
  current file, or the file named by <name> if the '-w' option is specified.
• markHilite - This is the 'Hilite' from the 'Edit'
  menu. If there is a currently hilited selection, the
  selection is unhilited, leaving the mark and the
  insertion point around the old selection. If there
  is not a selection, the region between the insertion
  point and the mark is selected.
• markMenuItem [-m] <menuName> <item text> <on|off> [<mark char>] - Either mark or unmark
  the menu item of user menu 'menuName' that has text '<item text>'.
  Note that unless the menu is not only created, but also already
  inserted, this command has no effect.
• matchBrace - moves the insertion point to the
  character that matches the character after the current
  insertion point
• matchIt <brace char> <pos> [<limit>] - Return pos of matching brace. Recognizes
  parenthesis, square brackets, and curly braces. Optional third argument
  specifies how many characters to search.
• maxPos [-w <win>] - returns the number of characters in the front
  window.
• menu [-s] [-n <name>] [-i <num] [-m] [-M <mode>] [-p <procname>] <list of menu items> -
  Defines a new menu named 'name' (if provided w/ '-n' option). The menu is not
  yet inserted into the menubar. The menu commands may be nested for
  heirarchical menus, see 'AlphaBits.tcl' for examples. Alpha massages the
  function names to make them look better in the menus.
  '-c'            Ignore any menu meta-chars. Can also be done on a per-item basis
                  by appending an ampersand ('&') to the end of an item.
  '-s'            Use system menu definition proc (faster).
  '-n <num>'    Resource id of icon suite to use for menu title. 'ics#'
                is the only resource that is really necessary.
  '-n <name>'    Name the menu. Not necessary for submenus.
  '-m'            No menu form. If not supplied, each menu item is split into
                  words at each capitalized letter.
  '-p <name>'     The tcl proc named by 'name' is called w/ the menu's name
                  and the item's contents when the item is chosen.
  '-M <mode>'    Specifies that any bindings created by the menu are
                  specific to a given mode. This is important because mode-specific
                  bindings over-ride global bindings.
• message <string> - prints 'string' on the status line.
• mkdir <name> - creates a directory (folder) named
  'name' in the current directory.
• mousePos - Returns list <row,col> of mouse position, if the mouse is
  currently over the active window. Otherwise, return error (catch w/
  'catch').
• moveInsertionHere [-last] - move the insertion point to the
  first (or last) line displayed
• moveFile <fromName> <toName>
  This command will move the file fromName to toName, overwriting any
  existing file. The move can not be made across volume (disk drives)
  boundaries.
• moveWin [win name] <left> <top> - moves current or specified window.
  The window name can be "StatusWin".
• mtime <time> [long|short|abbrev]
  Returns a date and time string using the Macintosh International Utilities. The
  long/short/abbrev specification corresponds to the date. These are the following
  formats:
    short        3/16/92 9:20:46 PM
    abbrev    Mon, Mar 16, 1992 9:20:49 PM
    long        Monday, March 16, 1992 9:20:43 PM
  The returned value actually is in the form of a list. To get text as
  above, run the result through 'join', as in "join [mtime [now] short]".
• nameFromAppl '<app sig>' - Interrogates the desktop database for the first
  existing app that has the desired signature. <app sig> is four chars
  inside single quotes.

                                    strings only, using the simple heuristic
                                    of assuming the first two double quotes
                                    constitute a string.
