              Using Alpha as Frontier's external editor

			  				 Frontier menu 2.1.6
				    		    June 2001


This document explains how to use Alpha as Frontier's external editor.

For help how to use Alpha as an HTML editor see "HTML Help", the manual for
HTML mode.

Please see the HTML mode home page, <http://go.to/alpha_www_tools> for the
latest version of HTML mode and Frontier menu. There you can also download
the HTML mode manual if you haven't got it already.

The code has been tested with Frontier 4.2.3, Frontier 5.0, and Frontier 
5.1.5.

I have two mailing list for information about updates, one for HTML mode 
and one for Frontier menu. If you want me to put you on my lists, send me a 
mail and tell me which lists you want to be on.

	  	Acknowledgments

Almost immediately after I had released Frontier menu 1.0 I got to know that
Danis Georgiadis <dmg@hyper.gr> also had written some code to integrate 
Alpha and Frontier. He generously gave me his code to freely use together 
with mine. In this version I have taken the parts from his code which 
could easily be integrated with mine and which worked without problems. The 
Frontier database browser and the Scripts menu are both made by him. 
When I made the Frontier shell I used some of Danis' code and some from 
Matlab mode by Stephen Merkowitz <merk@lnf.infn.it>.

	  	Installation and configuring

	Installing verbs into Frontier

The five files

	system.startup.clearAlphaFiles
	shutdown.closeAlphaWindows
	system.verbs.apps.Alpha
	user.html.editors.Alpha
	user.Alpha

must be imported into Frontier. You find these in the folder
Frontier verbs. Just double-click the files to import them. Frontier 
will ask for a name of the imported objects. Use the ones suggested.

	Upgrading from version 2.1.2, 2.1.3, or 2.1.4

None of the above files have been changed since version 2.1.2, 2.1.3 and 
2.1.4.

	Upgrading from version 2.1.1

Only the file 

	system.verbs.apps.Alpha 

has to be imported into Frontier. 
The other files have not changed since version 2.1.1.

	Upgrading from version 2.0.x

Only the three files

	system.verbs.apps.Alpha
	system.startup.clearAlphaFiles
	shutdown.closeAlphaWindows

have to be imported into Frontier. The other two files have not changed 
since version 2.0.x.

	Upgrading from version 1.0

All five files have to be imported into Frontier. The ones distributed with 
Frontier menu 1.0 are not compatible with Frontier menu 2.1.4.

	Other necessary changes to the Frontier database

There are also a few more changes you must do in Frontier:
 Change the path in user.odbEditors.TextEditor to the path to Alpha, 
otherwise Frontier will use the default editor BBEdit.
 Similarly change the path in system.verbs.apps.Alpha.appinfo.path
 A small change must be made to the verb suites.odbEditor.editors.Text.edit

The last lines reads

bundle send an Apple Event to the editor to open the temp file
	use an open protocol that's implemented by BBEdit 4.0 and greater
		the extra parameter to the odoc event is Frontier's app id
	appleEvent (ideditorapp, 'aevt', 'odoc', '----', alias (tempfile), 'FSnd', Frontier.id)
	
Change them to 
bundle send an Apple Event to the editor to open the temp file
	if defined(Alpha.id) && ideditorapp == Alpha.id
		Alpha.edit(tempfile)
	else
		use an open protocol that's implemented by BBEdit 4.0 and greater
			the extra parameter to the odoc event is Frontier's app id
		appleEvent (ideditorapp, 'aevt', 'odoc', '----', alias (tempfile), 'FSnd', Frontier.id)

This change is needed because Alpha doesn't understand the Apple event used 
in the last line. Hopefully Alpha will understand it in the future so that 
you don't have to make this change in the future. If you decide to switch 
back to your previous editor you don't have to undo the above change. It 
will work as before with any other editor.

	  	Inserting the Frontier menu in the menu bar

The Frontier menu doesn't automatically appear in the menu bar. To insert
it in the menu bar select Frontier menu in the dialog box "Config ->
Preferences -> Menus".


	  	Opening a Frontier text window in Alpha

Text windows in Frontier can be opened in Alpha using 'Edit with App' in 
Frontier's Main menu. Whenever you save changes the Frontier database is 
automatically updated. If you use 'Save as...' in Alpha the new file is 
disconnected from the Frontier database.

You can also use the Frontier database browser, see below.

	  	Frontier menu

	Switch to Frontier 

Launches Frontier or brings it to front if already running.

	Preview Page    

Makes Frontier render the page and sends it to the browser for previewing.
This is the same as 'Preview Page' in Frontier's Web menu (or 'View in
Browser' in Frontier 4.2.3). This should only be used for files opened from
Frontier. Other HTML files are sent to the browser using 'Send File to
Browser' in the HTML menu.
				  
	Publish Page   

Makes Frontier render the page and publish it. This is the same as 'Publish
Page' in Frontier's Web menu. (This function only works together with
Frontier 5.)

	Frontier Shell 

Opens a shell window where you can run Frontier scripts, see below.
				  
	Browse 

Opens a Frontier browser at different points in the database. Use Add
and Remove to edit this menu.

	Open 

Opens a Frontier window in Frontier. Use Add and Remove to edit this
menu.

	Scripts Menu 

Rebuilds the Scripts menu and loads the script corresponding to the menu
items.

	Preferences 

To set your preferences for Frontier. Currently you can choose if you want
to automatically launch Frontier when you launch Alpha. This is not done by
default.

	  	Scripts menu

The Scripts menu is a menu which you define inside Frontier in the same way as 
you define shared menus for other applications. (The Scripts menu has the 
cowboy menu icon like the Frontier scripts in the Finder.) The menu definition 
must be in user.Alpha.menubar. Alpha does not support menu sharing. Therefore 
there are a few things which differ from how shared menu work. In particular:

 If you launch Frontier after Alpha the menu it not automatically inserted 
in the menubar. You have to use 'Rebuild Scripts Menu' to insert it.
 Whenever you modify the menu you have to use 'Rebuild Scripts Menu' to 
rebuild it. Note! This has also to be done when you modify a script belonging 
to a menu item.
 Keybindings for the menu items must be defined the way Alpha defines 
keybindings. Alpha uses certain meta characters to define menu items. See 
the section 'Menus, user-Defined' in the "Alpha Manual".

	  	Frontier database browser

The Frontier database browser lets you navigate through Frontier's 
database without leaving Alpha. You can also open Frontier windows in 
Alpha without leaving Alpha. In the browser windows, tables are red, text 
windows are green, and everything else is blue. To navigate the windows 
you can use key shortcuts similar to those used to navigate Finder windows.

	uparrow

move up one line

	downarrow 

move down one line

	rightarrow 

rightarrow on a table displays the content of the table.

	leftarrow 

leftarrow on a table hides the content of the table.

	cmd uparrow

opens the parent table in a new window.

	cmd-opt uparrow 

opens the parent table in a new window and closes the current window.

	cmd downarrow 

cmd downarrow on a table opens a new window with the content of that table.

	cmd-opt downarrow 

cmd-opt downarrow on a table opens a new window with the content of that
table and closes the current window.

	return 

opens the selected object for editing. Text objects are opened in Alpha,
and most other things are opened in Frontier.

	  	Frontier shell

The Frontier shell is an alternative to the Frontier Quick Script window 
for those who like a command history. Type a command and hit return to have it 
executed in Frontier. The return value is then displayed on the next line.

You move up and down the command history using control-uparrow and 
control-downarrow.

Control-u erases the current line.

WARNING! Don't send commands which will make Frontier open an alert window, 
like e.g. dialog.notify. If this window is hidden behind your other 
windows it will freeze your machine with command-option-escape as the only 
way out.

	  	Option-click in titlebar

Option-clicking in the titlebar of the Frontier shell window pops up a menu 
with the command history. Selecting an item from this menu inserts the 
text in the window. If the option key is held down while you select the 
menu item the command is immediately evaluated, otherwise it is only 
inserted so that you can edit it before evaluating it.

	  	Version history

	2.1.6, 9 June 2001

 Compatibility update for Alpha 8.

	2.1.5, 30 April 1999

 In Alpha 7.2 windows with names containing brackets were not saved in 
Frontier. Fixed!

	2.1.4, 25 April 1998

 Fixed a startup problem. Alpha wouldn't launch completely when being 
launched by dropping a file on it while Frontier was running, or by using 
Edit with App in Frontier. 

	2.1.3, 1 March 1998

 Compatibility fix for Alpha 7.1.

	2.1.2, 7 February 1998

 Made 'View in Browser' compatible with Frontier 5, and renamed the menu 
item to 'Preview Page', which it's called in Frontier 5.
 Added 'Publish Page'. This only works with Frontier 5.
 Improved error handling. In some cases Alpha would previously show 
incorrect error messages.
 Option-click in title bar of Frontier shell window pops up a menu with 
the command history.
 'Save as' now disconnects the window from the database, which is more 
logical than the previous setup.
 Some small bug fixes.

	2.1.1, 3 November 1997 [update of version 2.0.1]

 The same as version 2.1 but for Alpha 7.0.

	2.1, 3 November 1997 [update of version 2.0]

 A startup and a shutdown script to be imported into Frontier have been 
added. Together they solve a problem which sometimes prevented the windows to 
be saved into Frontier's database. The shutdown script closes all open 
Frontier windows in Alpha. Thanks to Mike Carney <mike_carney@mediaone.net> 
for ideas and some code snippets.
 Various problems for windows with names containing brackets have been 
fixed.

	2.0.1, 19 October 1997

 Updated to be compatible with Alpha 7.0.

	2.0, 17 August 1997

 Added a Frontier shell.
 Added database browser and a Browse submenu.

 Added Scripts menu, which is defined in Frontier as with other apps.
 'Save as...' works now.

	1.0, 20 July 1997

First public release.
