1. Disclaimer
=============
Although I have tested SlyEdit, I cannot guarantee that it is 100% bug free or
will work as expected in all environments in all cases.  That said, I hope you
find SlyEdit useful and enjoy using it.


2. Introduction
===============
SlyEdit is a message editor that I wrote in JavaScript for Synchronet, which
can mimic the look and feel of IceEdit or DCT Edit.  SlyEdit also supports
customization of colors via theme files, cross-posting into other message
areas, text search, and file import & export (works with files on the
BBS machine, and is enabled only for the sysop).

The motivation for creating this was that IceEdit and DCT Edit were always
my two favorite BBS message editors, but in a world where 32-bit (and 64-bit)
Windows and *nix platforms are common, 16-bit DOS emulation is required to run
IceEdit and DCT Edit, which is noticeably slow and sometimes unreliable.
Since SlyEdit is written in JavaScript, it is faster than a DOS-based message
editor and can run in any environment in which Synchronet runs, without any
modification or being re-compiled.

SlyEdit will recognize the user's terminal size and set up the screen
accordingly.  The width of the edit area will always be 80 characters and
support up to 79 characters; however, an increased terminal size will provide
more room for message information to be displayed.  Also, a terminal height
greater than the standard 24 or 25 characters will provide a taller edit area,
allowing more of the message to be seen on the screen at a time.

Also, SlyEdit has no moving parts that can wear out over time.

Thanks go out to the following people for testing:
- Nick of Lightning BBS (lightningbbs.dyndns.org) for testing early versions
- Nick (AKA Access Denied) of The Pharcyde (pharcyde.org) for testing the
  newer versions and for his input on various features, mainly message quoting
- echicken (sysop of Electronic Chicken) for his solution to look up the
  original author of a message after a user changes the "To" name when
  replying to a message

3. Installation & Setup
=======================
These are the steps for installation:
 1. Extract the archive.  If you're viewing this file, then you've probably
    already done this. :)
 2. There are 2 ways SlyEdit's files can be copied onto your Synchronet system:
    1. Copy the JavaScript files into your sbbs/exec directory and the .cfg files
       into your sbbs/ctrl directory.  If you plan to customize your SlyEdit.cfg
       or color theme files, it's recommended to also put the .cfg files in your
       sbbs/mods directory so that your configuration won't be accidentally
       overwritten when updating the files from the Synchronet CVS repository.
       SlyEdit will first check the sbbs/mods directory for the configuration
       files, then sbbs/ctrl, and then SlyEdit's own directory for the
       configuration files.  In other words, the SlyEdit configuration files
       in sbbs/mods take first precedence, sbbs/ctrl 2nd precedence, and
       SlyEdit's own directory takes last precedence for the configuration
       files.
    2. Copy all files together into their own directory of your choice
 3. Set up SlyEdit on your BBS with Synchronet's configration program (SCFG).

SlyEdit can be set to mimic IceEdit or DCT Edit via a command-line parameter.
The values for this parameter are as follows:
  ICE: Mimic the IceEdit look & feel
  DCT: Mimic the DCT Edit look & feel
  RANDOM: Randomly select either the IceEdit or DCT Edit look & feel

To add SlyEdit to Synchronet's list of external editors, run Synchronet's
configuration program (SCFG) and select "External Programs", and then
"External Editors".  The following describes setting up SlyEdit using the
ICE parameter for IceEdit emulation:
 1. Scroll down to the empty slot in the editor list and press Enter to
    select it.
 2. For the external editor name, enter "SlyEdit (Ice style)" (without the quotes)
    (or similar, depending on your personal preference)
 3. For the internal code, use SLYEDICE (or whatever you want, depending on your
    personal preference)
 4. Press Enter to select and edit the new entry.  Asuming that the .js files
    are in the sbbs/exect directory, the settings should be as follows (the
    wording and options shown may vary, depending on the version of Synchronet
    you have installed):
      Command line: ?SlyEdit.js %f ICE
      Access requirement string: ANSI
      Intercept standard I/O: No
      Native (32-bit) Executable: No
      Use Shell to Execute: No
      Record Terminal Width: Yes
      Word-wrap Quoted Text: Your decision - Wrap to specific width, 80, or no
      Automatically Quoted Text: All
      Editor Information Files: QuickBBS MSGINF/MSGTMP
      Expand Line Feeds to CRLF: Yes
      Strip FidoNet Kludge Lines: No
      BBS Drop File Type: None
    After you've added SlyEdit, your Synchronet configuration window should look
    like this:

    +--------------------------------------------------------------------+

    For DCT Edit mode, use DCT in place of ICE on the command line.  For
    random mode, use RANDOM in place of ICE.

    Note that if you placed the files in a different directory, then the
    command line should include the full path to SlyEdit.js.  For example,
    if SlyEdit was placed in sbbs/xtrn/SlyEdit, then the command line would
    be /BBS/sbbs/xtrn/DigDist/SlyEdit/SlyEdit.js %f ICE


4. Features
===========
As mentioned earlier, SlyEdit is can mimic the look & feel of IceEdit or
DCT Edit.  It also has the following features:
- Message quoting: When replying to a message, users can select lines from the
  message to quote.  By default, SlyEdit puts the initials of the original
  author in front of the quote lines to indicate who originally wrote those
  parts of the message.  Optionally, sysops may disable the use of initials
  in quote lines, in which case SlyEdit simply prefixes quote lines with " > "
  as was done in IceEdit, DCT Edit, and other editors of the early-mid 1990s.
- Cross-posting into other message sub-boards: When posting a message to a
  message sub-board, SlyEdit allows the user to select other message sub-boards
  to post the message into.  SlyEdit will post the message to the user's
  current message sub-board by default.  Using the cross-post feature, the
  user can select any number of other message sub-boards to cross-post his/her
  message into.  SlyEdit respects the ARS security setting for each sub-board -
  If a user is not allowed to post in a message sub-board, SlyEdit will not
  allow the user to select that sub-board for cross-posting.  The user can also
  un-select their current message sub-board.  When the user un-selects their
  current message sub-board and chooses other message sub-boards to post
  his/her message into, Synchronet will say that the message was aborted
  because the message file wasn't saved as it normally is for the current
  message sub-board.  However, SlyEdit will output all of the message
  sub-boards that the message was posted into.  If the user un-selected their
  current message sub-board, SlyEdit will also output a note explaining that
  the BBS will say the message was aborted, even though it was posted into
  other sub-boards and that is normal.
- Text search: Allows the user to search for text in the message.  If
  the text is found, the message area will scroll to it, and it will be
  highlighted.  Repeated searches for the same text will look for the
  next occurrance of that text.
- Allows changing the message subject
  Note: If using a Synchronet 3.17c development build (pre official release),
  you will need a build from July 21, 2019 or newer.
- Navigation: Page up/down, home/end of line, and arrow keys
- Slash commands (at the start of the line):
  /A: Abort
  /S: Save
  /Q: Quote message
  /C: Cross-post message sub-board selection
- Sysops can import a file (stored on the BBS machine) into the message
- Sysops can export the current message to a file (on the BBS machine)
- Configuration file with behavior and color settings.  See section 4
  (Configuration File) for more information.
- Spell check

The following is a summary of the keyboard shortcuts, from SlyEdit's command
help screen (note that file import, with Ctrl-O & Ctrl-X, are only available to
the sysop or users with sysop access, and file import/export takes place on the
BBS machine):

5. Digital Distortion Message Lister note
-----------------------------------------
If you use Digital Distortion's Message Lister, you must update it to version
1.36 or newer in order to properly work with this version of SlyEdit when
replying to messages.  See the file "Message Lister notes.txt" for a more
detailed explanation.

6. Configuration file
=====================
The configuration file, SlyEdit.cfg, is split up into 3 sections -
Behavior, Ice colors, and DCT colors.  These sections are designated
by [BEHAVIOR], [ICE_COLORS], and [DCT_COLORS], respectively.  These
settings are described below:

Behavior settings
-----------------
Setting                           Description
-------                           -----------
displayEndInfoScreen              Whether or not to display the info
                                  screen when SlyEdit exits.  Valid values
                                  are true and false.  If this option is
                                  not specified, this feature will be
                                  enabled by default.

userInputTimeout                  Whether or not to use an input timeout
                                  for users.  Valid values are true and
                                  false.  Note: The input timeout is not
                                  used for sysops.  If this option is not
                                  specified, this feature will be enabled
                                  by default.

inputTimeoutMS                    The amount of time (in milliseconds) to
                                  use for the input timeout.  If this option
                                  is not specified, this option will default
                                  to 300000.

reWrapQuoteLines                  Whether or not to re-wrap quote lines. Valid
                                  values are true and false.  This feature is
                                  enabled by default.  With this feature
                                  enabled, SlyEdit will re-wrap quote lines
                                  to still be complete and readable after the
                                  quote prefix character is added to the front
                                  of the quote lines.  SlyEdit is able to
                                  recognize quote lines beginning with >
                                  or 2 letters and a > (such as EO>).  If this
                                  feature is disabled, quote lines will simply
                                  be trimmed to make room for the quote prefix
                                  character to be added to the front.

allowCrossPosting                 Whether or not to allow cross-posting
                                  messages into different/multiple message
                                  sub-boards.  Valid values are true and false.

enableTextReplacements            Toggles the use of text replacements (AKA
                                  macros) as the user types a message.  Valid
                                  values are true, false, and regex.  If regex
                                  is used, text replacements will be enabled
                                  and used as regular expressions as
                                  implemented by JavaScript.  For more
                                  information, see section 10 (Text
                                  replacements (AKA Macros)).

tagLineFilename                   Specifies the name of the file that stores
                                  taglines, which users can optionally choose
                                  from to be appended to their message upon
                                  saving the message.

taglinePrefix                     Some text to be added to the front of
                                  a tagline that is selected from the user.
                                  The intention of this setting is to
                                  differentiate taglines from the rest of the
                                  message.  This defaults to the string "... "
                                  (3 dots and a space).  If desired, this can
                                  be set to a blank string (nothing after the
                                  =) - for instance, if you only want to put
                                  double quotes around text lines, you could
                                  set this to blank and enable the
                                  quoteTagLines setting.

quoteTaglines                     Whether or not to put selected taglines in
                                  double quotes.  This defaults to false.  If
                                  you like taglines to have double quotes and
                                  no prefix, you can set this to true and set
                                  taglinePrefix to a blank string (nothing
                                  after the =).

shuffleTaglines                   Whether or not to shuffle (randomize) the
                                  list of taglines displayed to the user for
                                  selection.

allowUserSettings                 Whether or not to allow users to configure
                                  their own user settings.  This defaults to
                                  true.

allowEditQuoteLines               Whether or not to allow the user to edit
                                  quote lines.  Valid values are true and
                                  false.  If this option is not specified, the
                                  default value is true.

allowSpellCheck                   Whether or not to allow spell check.  Valid
                                  values are true and false.  Defaults to true.
                                  You might want to disable spell check if,
                                  for instance, the spell check feature causes
                                  an "out of memory" error on your system.

useQuoteLineInitials              Whether or not to prefix quoted message lines
                                  with the previous author's initials when
                                  replying to a message.  Valued values are
                                  true and false.  If this setting is disabled,
                                  SlyEdit will simply prefix the quoted lines
                                  with " > ", as was done in IceEdit, DCT Edit,
                                  and other message editors of the early-mid
                                  1990s.  This setting is enabled by default.
                                  This setting serves as the default for the
                                  user setting, which users can configure in
                                  their own settings.

indentQuoteLinesWithInitials      When prefixing quoted messages lines with the

10. Text replacements (AKA Macros)
==================================
SlyEdit version 1.29 added text replacements (AKA Macros), which lets you (the
sysop) define words to be replaced with other text as the user types a message.
This feature can be used, for instance, to replace commonly misspelled words
with their correct versions or to replace swear words with less offensive
words.  This feature is toggled by the enableTextReplacements option in
SlyEdit.cfg can can have one of three values:
false : Text replacement is disabled
true  : Text replacement is enabled and performed as literal search and replace
regex : Text replacement is enabled using regular expressions as implemented by
        JavaScript (more accurately, Synchronet's JavaScript interpreter, which
        at the time of this writing is Mozilla's JavaScript engine (AKA
        JavaScript-C or "SpiderMonkey").

The text searches are performed on single words only, as the user types the
message, and are replaced by whatever text you configure for the word.  The
configuration for text replacing is read from a configuration file called
SlyEdit_TextReplacements.cfg, which is plain text and can be placed in either
sbbs/ctrl or in the same directory as SlyEdit's .js files (SlyEdit.js,
SlyEdit_Misc.js, etc.).  Each line in SlyEdit_TextReplacements.cfg needs to
have the following format:
originalWord=replacementText
where originalWord is the word to be replaced, and replacementText is the text
to replace the word with.

The options for the enableTextReplacements configuration optoin are explained
in more detail below:

- false: Text replacing is disabled

- true: Literal text search and replace - The words will be matched literally
and replaced with the text on the right side of the = in
SlyEdit_TextReplacements.cfg.  In this mode, word matching is not
case-sensitive.  The words can have both uppercase and lowercase letters and
will still be matched to the words configured in SlyEdit_TextReplacements.cfg.
In this mode, if the first letter of the original word is uppercase, then the
first letter of the replaced text will also be uppercase.
While this works, one drawback to literal text searching is that it won't
replace a word if there are punctuation characters or other characters around
the word or if the word is misspelled.

- regex: With this option, SlyEdit will treat the word searches (on the left
side of the = in SlyEdit_TextReplacements.cfg) as regular expressions, as
implemented by JavaScript.  When using regular expressions, SlyEdit will start
trying all the regular expressions provided and apply only the first one that
changes the text and will stop there.
Regular expressions offer a more flexible way to serach and replace text.  For
example, in case a word is surrounded by punctuation or other characters, a
regular expression can be given that will still match the word.  For example,
you might want a regular expression that changes "teh" to "the" (since "teh"
is a common misspelling of "the").  To ensure that the word is replaced even if
the word has other characters around it, you could use a regular exprssion and
replacement such as this:
(.*)teh(.*)=$1the$2
That way, even if the word is enclosed in quotes (such as "teh"), the word will
still be converted to "the".  And to preserve the first letter's case (if it's
uppercase or lowercase), this regular expression and replacement string would
handle that:
(.*)([tT])eh(.*)=$1$2he$3
SlyEdit applies the regular expressions on a per-word basis; that is, the
expression .* in a regular expression will match any characters only in the
last word the user typed, not the entire line.

For more information on regular expressions, the
following are some web pages that explain them:

General information about regular expressions:

Information on text grouping and backreferencing with parenthesis (the page
calls them "round brackets") - A very powerful feature of regular expressions:

General information about regular expressions geared toward JavaScript:

Information about using backreferences with regular expressions in JavaScript:

JavaScript-specific information on regular exprssions:
http://www.w3schools.com/js/js_obj_regexp.asp
http://www.w3schools.com/jsref/jsref_obj_regexp.asp

One nice thing about JavaScript's implementation (among others) of regular
expressions is that it supports the use of parentheses for character grouping
and backreferencing to place a portion of the matched text in the replacement
text.  In JavaScript, each numbered capture buffer is preceded by a dollar sign
($).  For example, the regular expression (darn) will match the word "darn" and
store it in buffer 1, and in JavaScript (and with SlyEdit's search and
replace), you would use $1 to refer to the word "darn".  For example, for
(darn), the replacement $1it would replace the word "darn" with "darnit".

11. User settings
=================
Since version 1.32, SlyEdit has the ability for each user to configure some
settings for themselves.  The user settings include the following:
- Whether or not to enable the option to use taglines
- Whether or not to prompt for spell checking when saving a message
- Whether or not to add the original author's initials to quote lines
  (this was previously only configurable in SlyEdit.cfg)
- Whether or not to indent quote lines that use author's intials (this was
  previously only configurable in SlyEdit.cfg)
- Whether or not to trim spaces from quoted lines (when replying to messages).
  Some users indent their paragraphs with spaces as a writing style.  When
  this setting is enabled, this feature removes leading spaces from quoted
  lines when replying to a message.  A user might want to disable this, for
  example, when they want to ensure that a message is quoted exactly as-is.
- Whether or not to auto-sign messages.  When this setting is enabled, the
  user's messages are automatically signed with their alias or their real
  name, depending on the sub-board's settings.  There is additionally a setting
  to specify whehter to use only their first name when signing with their
  real name, and also whether to sign emails with their real name (emails
  don't have a configuration like sub-boards do).
- Dictionaries for spell-check.  If there is only one dictionary configured,
  this option won't appear on the user options list.  If there are multiple
  dictionary files on the BBS machine (in either sbbs/mods, sbbs/ctrl, or in
  the same directory as SlyEdit), the user will be able to choose any or all
  dictionaries to be used for the spell check feature.  Multiple dictionaries
  can be selected, so if the user writes messages in more than one language,
  or if a message could contain multiple languages, the spell-check feature
  will use all selected dictionaries for spell checking.

The user settings files will be stored in the sbbs/data/user directory with the
filename <user number>.SlyEdit_Settings, and the user number will be 0-padded
up to 4 digits.

12. Taglines
============
SlyEdit version 1.32 added the ability for users to optionally choose a tagline
to be appended to their message upon saving the message.  Each user can
configure in their user settings whether or not they want to enable this
feature.  The setting enableTaglines in SlyEdit.cfg sets the default setting,
but users are free to change it for themselves.

The taglines are loaded from the text file SlyEdit_Taglines.txt, which can be
located in any of the following directories, searched in the following order:
- sbbs/mods
- sbbs/ctrl
- The same directory as SlyEdit's .js files

Synchronet version 3.16 has the ability to place the tag line after the user's
signature, so if you are running version 3.16 or newer of Synchronet, the tag
line will be placed after the user's signature, if the user has a signature.

Specifically, Synchronet 3.16 starting with the beta build on July 5, 2015 will
behave that way; with earlier versions of Synchronet, the tag line will be
placed before the user's signature.  On June 22, 2015, Synchronet added support
for a file called editor.tag (in each node directory's temp directory) which
can contain an editor tagline, and on July 5, 2015, Synchronet included an
update in which the full path & filename to the tagline file will be written
to line 7 of the MSGINF drop file, which SlyEdit reads on startup.  If the
MSGINF file includes the 7th line, then the tagline will appear after the
user's signature (if they have one).  If the MSGINF file does not include the
7th line, then the tagline will appear before the user's signature.

13. Spell check and dictionaries
================================
Since version 1.64, SlyEdit has a spell check feature.  Spell check can be
started by the user with the Ctrl-R hotkey, or by the Edit > Spell Checker
option in the DCT-style ESC menu (only available when in DCT mode).  For spell
check, SlyEdit will check each word to see if it exists in the configured
dictionary/dictionaries, and if not, it will prompt the user for a corrected
version of the word.  The sysop can configure one or multiple dictionaries in
SlyEdit.cfg with the dictionaryFilenames option.  Dictionary files need to be
in the format dictionary_<languageName>.txt, where <languageName> is the name
of the language.  Also, ideally, the language names should follow standard
language tags, as in "en-us" for English (US), etc.  See these web pages for
more information:
https://en.wikipedia.org/wiki/Language_localisation
http://www.lingoes.net/en/translator/langcode.htm
Also, the dictionary filenames will be parsed and the language name will be
used in the menu of dictionaries in the user options - The user is able to
enable/disable the configured dictionaries for their own use for the spell
checker.

For the dictionaryFilenames option in SlyEdit.cfg, you can specify a comma-
separated list of dictionary filenames.  The dictionary filenames are in the
format dictionary_<languageName>.txt, where <language> is the language name.
In this list, the filenames can be in that format, or just <languageName>.txt,
or just <languageName>.  You can leave the setting blank to use all dictionary
files that exist on the system.

SlyEdit will search for the dictionary files in the following directories, in
this order:
1. sbbs/mods
2. sbbs/ctrl
3. SlyEdit's own directory

Dictionary files must be sorted in order for word matching to work properly
(SlyEdit uses a binary search for quick word matching, which requires the words
to be sorted).  Also, all of the words in the dictionary files must be lower-
case, since SlyEdit does case-insensitive matching by converting words in the
message to lower-case and comparing them with the words in the dictionary.
