1. Disclaimer
=============
The only guarantee that I can make about these scripts is that they will take
up space on your computer.  I have tested these with the Windows verison of
Synchronet 3.15 and 3.16 in Windows 2000 and Windows XP, and Synchronet 3.17 in
Windows 7.
I created these scripts to customize the message & file area selection on my
BBS and am providing them to the Synchronet BBS community in case other
Synchronet sysops might find them useful.


2. Introduction
===============
The Digital Distortion message & file area chooser scripts provide a lightbar
or traditional user interface to let the user choose their message and file
area.  The colors are customizable via a configuration file.

By default, the scripts will let the user choose both the message group and
sub-board, and file library and directory - There is also a command-line
parameter that will only allow the user to choose a message sub-board within
their current message group, or file directory only within their current file
library, if desired.    Additionally, the message area
chooser will show the date & time of the latest post for each of the
sub-boards.

The user is able to change the sorting when displaying the items: The user can
press Ctrl-U to open a user settings dialog, which has an option to let them
change the sorting option.

The file & message area chooser scripts can be run in several ways:
- Executed from a JavaScript/Baja script
- Loaded in a JavaScript script, then use the DDMsgAreaChooser or
  DDFileAreaChooser object to let the user choose their message/file area
- Set up as a door

These scripts require Synchronet version 3.14 or higher.


3. Installation & Setup
=======================
Step 1: Copy the following files to a directory of your choice (i.e., sbbs/exec
or sbbs/mods):
DDFileAreaChooser.js
DDMsgAreaChooser.js
DDAreaChooserCommon.js
DDMsgAreaChooser.cfg
DDFileAreaChooser.cfg

Step 2: Set up the scripts to run on your BBS.  To do so, you will need to
update your command shell to execute the included script instead of
Synchronet's built-in area chooser functionality.  Synchronet does not use a
traditional menu system like some other BBS packages do; rather, Synchronet
uses a "command shell", which is a script that handles user input, performs
actions based on the user's input, displays menu files, etc.  If you have not
modified your Synchronet installation much, you may be using the default
command shell, which (at the time of this writing) is default.src and its
compiled version, default.bin, which is written in Baja (Synchronet's own
scripting language).  It's also possible to use a command shell written in
JavaScript - Synchronet includes a few examples, such as classic_shell.js.

For these examples, I will use DDMsgAreaChooser.js.

To use these scripts in a Baja script (such as the 'default' script mentioned
above), you can run the area chooser as follows:
exec "?DDMsgAreaChooser.js"

If you're using a JavaScript command shell, you can run it this way:
bbs.exec("?DDMsgAreaChooser.js");

To use the message area chooser in the 'default' command shell, search for the
text "msg_select_area" (without the double-quotes).  It should be underneath a
line that says "cmdkey J" (meaning the J key is used to jump to another message
area).  Replace msg_select_area with this line:
exec "?DDMsgAreaChooser.js"

The process is similar for the file area chooser - Search for file_select_area
and replace that with the following:
exec "?DDFileAreaChooser.js"

For example: If you are using the JavaScript command shell classic_shell.js, do
the following for message area selection (some knowledge of the JavaScript
language will be helpful):
- Search for the text "case 'J':" (without the double-quotes)
- Comment out the text from the next line until (and not including) the next
  case statement
- Underneath the "case 'J':" line, put the following two lines:
bbs.exec("?DDMsgAreaChooser.js");
break;

In classic_shell.js, the process will be similar for file area selection.

Command-line parameters
-----------------------
The first command-line parameter specifies whether or not to allow the user to
choose a message group (for the message area chooser) or file library (for the
file area chooser).  These parameters are true by default.  If you want to
allow the user to choose a message sub-board only within their current message
group, or file directory only within their current file library, add the word
"false" (without the double-quotes) as a command-line parameter after the .js
script filename.  For example:
For JavaScript:
bbs.exec("?DDMsgAreaChooser.js false");
bbs.exec("?DDFileAreaChooser.js false");
For Baja:
exec "?DDMsgAreaChooser.js false"
exec "?DDFileAreaChooser.js false"


If you would like to set up these scripts as doors, the following is an example
setup of the message area chooser (assuming it is placed in sbbs/exec or
sbbs/mods):

4. Configuration files
======================
If you want to change the default beavior and colors for one of these scripts,
you can edit its configuration files, which are plain text files.

DDFileAreaChooser.example.cfg and DDMsgAreaChooser.example.cfg are example
configuration files for the file area chooser and message area chooser,
respectively. If you want to customize your configuration, copy
DDFileAreaChooser.example.cfg to DDFileAreaChooser.cfg and
DDMsgAreaChooser.example.cfg to DDMsgAreaChooser.cfg (they can be in the same
directory, xtrn/DDAreaChoosers, or in sbbs/mods) and make your customizations.

The configuration files have two sections: A behavior section (denoted by
[BEHAVIOR]) and a colors section (denoted by [COLORS]).  For each setting or
color, the syntax is as folows:

setting=value

where "setting" is the behavior setting or color, and "value" is the corresponding
value for the setting/color.  The colors are Synchronet color codes.

Also, comments are allowed in the configuration file.  Comments begin with a
semicolon (;).

For the color settings, the colors specified for each setting can simply be a
list of the color attribute characters.  For instance, for normal white: nw
Or, for high cyan: ch

Behavior section: Message area chooser
--------------------------------------
Setting                               Description
-------                               -----------
useLightbarInterface                  true/false: Whether or not to use a
                                      lightbar user interface.

showImportDates                       true/false: Whether or not to show the
                                      import dates (rather than message dates)
                                      in the latest date & time column in the
                                      sub-board lists.

areaChooserHdrFilenameBase            The filename to use (without the
                                      extension) for a header to display above
                                      the message area chooser list.  For
                                      example, if areaChgHeader is specified,
                                      then the chooser will look for
                                      areaChgHeader.ans if it exists, and if
                                      not, the chooser will look for
                                      areaChgHeader.asc.  Additionally, you
                                      can have multiple header files for
                                      different terminal widths; fpr example,
                                      areaChgHeader-80.ans for an 80-column
                                      terminal, areaChgHeader-140.ans for a
                                      140-column terminal, etc.

                                      & time of the latest message in the
                                      sub-boards.  Valid values are true and
                                      false.

useSubCollapsing                      Whether or not to enable sub-board name
                                      collapsing.  For example, for sub-boards
                                      in a group starting with common text and
                                      a separator (specified by
                                      subCollapseSeparator), the common text
                                      will be the only one displayed, and when
                                      the user selects it, a 3rd tier with the
                                      sub-boards after the separator will be
                                      shown.

subCollapseSeparator                  The separator to use for sub-board name

5. Sub-board & directory name collapsing
========================================
Sub-board name collapsing (for message areas) and directory name collapsing (for
file areas) is a way to simplify long lists of sub-boards and file directories
that share a common theme.  If you use a separator character (such as :, and it
can be configured) in your message library/sub-board and file library/directory
names, the 'collapsing' feature will split the menus up into multiple tiers of
options. For instance, if you have a file library called "Mirror:Simtelnet" and
directories in there such as "C-Net:Mac:Business" and "C-Net:Mac:Games:action",
the menu heirarchy will be arranged as follows:
Mirrors
  Simetlnet
    C-Net
      Mac
        Business
        Games
          Action
This only affects how the areas will be displayed in the menus; your configured
areas will be unaffected.

Another example: If you have the following file directory structure:
BBS files
  DOS: BBS software
  DOS: BBS doors
  DOS: BBS utilities
  Windows: BBS software
  Windows: BBS doors
  Windows: BBS utilities

With directory name collapsing enabled, the selection will be come 3 tiers, as
follows:
BBS files
  DOS
    BBS software
    BBS doors
    BBS utilities
  Windows
    BBS software
    BBS doors
    BBS utilities

The message area chooser has the same functionality for sub-boards as the file
area chooser.

You can configure what text to split the names on (i.e, by default, it splits
on a colon, :).

Name collapsing for message areas can be configured with the useSubCollapsing
and subCollapseSeparator options in DDMsgAreaChooser.cfg, and for files, with
the useDirCollapsing and dirCollapseSeparator options in DDFileAreaChooser.cfg.

If all of the sub-boards in a message group or all directories in a file library
have the same separator, then those will not be collapsed, since that would
result in only a single 2nd-tier selection, which would not be useful.

If you want to use the separator character but don't want the item to be
collapsed, you can put the separator in the name twice in a row. Also, for those
instances, the separator character will be displayed just once instead of twice.
For example, if you wanted a file library literally displayed as "Linux: Games",
and you have : configured as the separator character, you could name the library
"Linux:: Games".  This only applies when name collapsing is enabled; if
disabled, the name will be displayed as-is with the double character.
