Why Lyntin
==========
Lyntin is written entirely in Python--a nicely written and very
portable programming language. Thusly Lyntin is platform
independent. Lyntin is exposes the Python interpreter allow you
more freedom than mere 'if you see this then send this' aliases
and triggers. They can be Python functions which do anything
from setting a variable to forking a web spider. In addition,
your code can interface with Lyntin's code.
Lyntin is great if:
1. you want a mud client that you can see the source code to
and adjust it to suit your needs
2. you want a mud client that has a sophisticated API for
enhancing and building bots/agents/triggers more advanced than
"if you see this then do this"
3. you want a mud client that works on all your machines,
has a text ui, a tk gui, and can also work over ssh/telnet
Lyntin is not great if:
1. you prefer wizards and menus to the command line
2. you hate Python
3. you want fancy bells and whistles in the ui
Operating System Notes
======================
Lyntin works in most environments we can think of, but it has some
caveats with the various operating systems due to differences
between them.
Windows
-------
Windows users should use either ``\`` or ``/`` to denote directory
separaters.
Examples::
#write c:\commandfile
#write c:/commandfile
RedHat Linux
------------
Depending on which version of RedHat Linux you have, you will have
to install the Python RPM as well as the Python Tkinter RPM. If
you don't install the Tkinter RPM, then you won't be able to use
the Tk ui and it'll complain that it's missing a library when you
try.
Mac OSX
-------
I have no experience with Mac OSX but after reading the various
pages on Python and how it works on OSX, I'm hesitant to say
Lyntin is fully supported. However, I don't know of any reason
it shouldn't be supported either except that one person on the
mailing list has had problems with getting #write to work.
Other Notes
-----------
If you encounter other operating system issues, let us know both
the problem and the solution so we can add them here.
Getting Started
===============
Type ``#help help`` for help on how to use the in-game help system.
Read through the ``#help readme`` topics. These will help as they
will walk you through how Lyntin works, how to get additional
help, where to go for answers, and what to do if you find a bug.
These are also exported into the ``README`` file.
You should read through the topics in ``#help commands`` for all
the currently registered Lyntin commands.
Each user interface has its own help topic--these will be on the
top level of the help structure.
To start, the ``#session`` command will allow you to start a
session. When you're done, ``#end`` will close Lyntin.
All documentation that comes with Lyntin is also available on the
Lyntin web-site. If you find problems with the documentation or
have fixes for it, let us know on the lyntin-devl mailing list.
Lyntin Command Handling
=======================
Lyntin uses Lyntin commands to allow you to manipulate the Lyntin
client and setup your session with aliases, variables, actions,
and such. Commands start with the command character--by default
this is ``#``. It can be changed with the ``#config`` command. The
command character can also do some other special things:
1. You can execute commands in another session by typing the
command character and then the sesion name then the command.
Example::
#3k say hello - will say hello in session 3k
#a #info - will run the #info command in session a
2. You can switch to another session by typing the command
character and then the session name. Examples::
#a - will switch to session a (if it exists)
#3k - will switch to session 3k (if it exists)
3. You can execute a command in all sessions by typing the
command character then all. Examples::
#all say hello - will run "say hello" in all sessions
4. You can execute a command a number of times by typing the
command character then a number, then the command. Examples::
#5 say hello - will run "say hello" 5 times
Commands are separated by the semicolon. Semicolons can be
escaped with the ``\`` character. Examples::
say hello;wave - will run "say hello" then "wave"
say hi! \;) - will run "say hi! ;)"
Command arguments can be enclosed with ``{`` ``}``. This enables you to
specify arguments that have spaces in them. Examples::
#alias a b - executes #alias with args "a" and "b"
#alias {a} {b} - executes #alias with args "a" and "b"
#alias {a} {say hi} - executes #alias with args "a" and "say hi"
#alias a say hi - executes #alias with args "a", "say",
and "hi" which will kick up an error
(since the #alias command doesn't accept
a third string argument)
``{``, ``}`` and ``\`` can all be escaped with the ``\`` character:
``\{``, ``\}``, and ``\``.
Variable Evaluation
===================
Variables get evaluated according to a new methodology we developed
after disliking the Tintin way of doing things. This new methodology
provides maximum flexibility and provides for some things that
the Tintin variable evaluation did not provide for.
* Variables and placement variables with a single ``$`` or ``%`` are
evaluated/expanded. One layer of ``$``s or ``%``s is then stripped
off when this evaluation occurs.
* Variables are matched by length of name. So if you have two
variables ``a`` and ``ab``, we'll test to see if the variable is
``ab`` before ``a``. We also handle bracing of variable names
like ``${a}`` and ``${ab}`` which will guarantee unambiguosity.
* Variable expansion is always done on user input before
commands are evaluted. This means variables can be used as
arguments to any commands, etc. It also means that if you
want the variable actually in the command, you have to prepend
another ``$``.
* Variable expansion happens again when certain expressions are
evaluated, such as action triggers, alias expansion, etc.
Essentially, when any stored value gets expanded its variables
will get expanded (typically whenever tintinmode would do its
sole expansion.)
* Placement vars in actions and aliases support an expanded
syntax based on python array slices. ``%0:1`` will evaluate to
the first and second arguments, while ``%0:`` will be all
arguments, and ``%:-1`` will be all but the last argument, etc.
Examples:
1. ``#action {$Myvar} {woo}``
Will trigger whenever the value ``Myvar`` holds when this is entered
(the original value of ``Myvar`` - it will not change if ``Myvar``'s
value changes)
2. ``#action {$$Myvar} {woo}``
Will trigger whenever the current value of ``Myvar`` passes by.
3. ``#action {$$$Myvar} {woo}``
Will trigger whenever the literal string ``$Myvar`` is seen. Place
more ``$``s in if you wish to trigger on more of them, the first 2
will be stripped by the variable expansion processes.
4. ``#alias {hello} {$moo}``
Will bind ``hello`` to ``$moo``'s current value.
5. ``#alias {hello} {$$moo}``
Will bind ``hello`` to always expand to ``moo``'s current value at
the time of expansion.
6. ``#alias {hello} {$$$moo}``
Will bind ``hello`` to expand to the literal string ``$moo``
7. ``#alias {hello} {$${moo}}``
Will bind ``hello`` to expand to ``moo``'s current value at the time of
expansion.
Lyntin's Regular Expression Syntax
==================================
Lyntin allows the use of regular expressions in various arguments
for commands like ``#action``, ``#highlight``, and such. It uses a
specific format to trigger using raw regular expressions rather
than having your argument get escaped so it can be compiled into
a regular expression. This allows you to write arguments using
the simplest form that you can without having to adjust toggles
and such.
For example::
#highlight {red} {*says:}
is the same as::
#highlight {red} {r[^.*?says:]}
The first one will undergo escaping and get transformed into
``^.*?says\:`` (without the quotes) before being compiled into a
regular expression.
The second one gets compiled without being escaped.
If you want to pass an "ignorecase" flag, do so after the end
``]``::
#highlight {red} {r[krynor]i}
will highlight all instances of ``krynor`` (ignoring case) as red.
For regular expression documentation, refer to the Python
documentation at http://www.python.org/doc/current/lib/re-syntax.html .
Note: It may have moved since this was written.
Bug Reports, Questions, Comments, Curses?
=========================================
Lyntin was originally written by Lyn Headley. Lyntin was them maintained
by Will Guaraldi (willhelm@users.sourceforge.net) from 1.3.2 to 4.0.
Lyntin is now being maintained by Eugene.
We appreciate ALL types of feedback.
Inevitably you will either run across a bug in Lyntin or the need
for a feature to be implemented. When this happens, we ask you
to provide as much information as you can:
* operating system, version of Python and version of Lyntin
(from ``#diagnostics``)
* stacktrace (if it's a bug and kicked up a stacktrace)
* explanation of what happened vs. what should be happening
* any other pertinent information
Enter this in the bugs forum or send it to the mailing list. Details for
both are on the Lyntin web-site http://lyntin.sourceforge.net/ .
How To Contribute
=================
Development and maintenance is entirely managed by the maintainer
right now. If you're interested in sending in bug fixes, please
feel welcome. I'm extremely accomodating to most methods of
sending in patches, however a ``diff -u`` against the code in cvs is
great for this sort of thing.
All patches and such things should be sent to the mailing list at
lyntin-devl@lists.sourceforge.net/ .
NOTE: Patches will not be applied unless the author either yields
the copyright to the FSF or to me (and then I'll yield it to the
FSF).
Please read through the web-site areas on coding conventions and
such before sending in code.
Errata
======
The latest release of Lyntin is always available from
http://lyntin.sourceforge.net/ in the ``download`` section. We also
have snapshots of what's in CVS in the ``development`` section.
When communicating bugs or feature requests INCLUDE AS MUCH
INFORMATION AS POSSIBLE. If you don't, I'll just ask you for
it anyhow.
In-game help is accessed by typing ``#help``. When you start
Lyntin for the first time, type ``#help general`` and that'll
get you started. Read through the various help files at your
leisure.
Enjoy!
the Lyntin development folks
