This program is an alternative preferences editor for OpenURL. It is a MUI
application written in ARexx, developed on an A4000/040 with AmigaOS 3.9 +
BoingBags 1 & 2, MUI 3.8, RxMUI 42.6, RoyalBridge 1.1, and OpenURL 7.0. It
differs from the original editor in that client data are edited in the main
window rather than separate edit windows. Unlike the original, but like the
standard editors, it supports the usual startup options, and has Open, Save As,
and Create Icons menu items. In addition, it has pop-up edit menus for the
client listviews and the general options gadgets, it disables the edit menu
items when they have nothing to do, and the window is an AppWindow which will
load a dropped preferences file.
The Create Icons setting is automatically saved and loaded separately from the
OpenURL settings when the program quits and starts.
When you edit the strings, inserting a path or placeholder using the pop-ups
enters the value into the list, but after typing or pasting, the value is
entered only when you press return. The string gadgets use the Textinput MUI
custom class, which supports drag-marking. The pop-up selection replaces the
marked portion of the value or inserts at the last accessed position.
This program disallows control characters in the string gadgets. The original
editor also rejects typed control characters, so it is presumably unintentional
that it accepts them when they are pasted in.
I use an icon datatype class, util/dtype/IconDT44.lha, so several About windows
look a bit prettier.
The links in the About requesters use OpenURL. To make the About address link
work, in OpenURL preferences I edited my mailer command's address argument so
the keyword is joined to its value by a space instead of an equals sign. The
equals sign apparently exposes a bug in dos.library/Execute() that assumes an
angle bracket indicates a stream redirection.
This program is a demonstration of the power of ARexx and RoyalBridge to access
arbitrary libraries (in this case openurl.library). By releasing this script, I
hope to encourage more development in ARexx.
When saving a preferences file, if Create Icons is checked and the icon file
doesn't already exist, the program will copy the file Env:Sys/def_prefs.info or
the system will provide a default project icon: Env:Sys/def_project.info or an
internal image. The new icon will have a Cmd tool type which specifies the
preferences file and also a copy of the program's Console tool type. However, if
the program's absolute path contains a space, the tool types won't be written.
If the program receives options from the command line or from the Cmd tool type,
it processes them with the following argument template. Otherwise, it reads its
options as tool types with the same keywords.
From,Edit/S,Use/S,Save/S,PubScreen/K
PubScreen overrides the corresponding setting in MUI preferences.
Known Problem
When the mouse pointer is over a gadget that has a context menu, a menu item
keyboard shortcut has the right-Amiga key stripped from it. For example, with
the mouse over a listview, the shortcut for Edit > Reset to Defaults presses the
Down button instead, and the Project > Quit shortcut does nothing. I'm told this
problem is gone in MUI 3.9.
History
1.4 Fixed bug: Last fix was broken.
1.3 Fixed bug: Mishandled 32-bit memory address values.
1.2 Fixed bug: Inserting Start path from file requester failed to update
disabled states of window and pop-up edit menu items.
1.1 Fixed bug: If Save or Use button failed, program would quit anyway.
1.0 First Aminet release.
I welcome your comments and questions.
