About This Module
=================
This crux of this module is the Terminal class which is a pure-Python
implementation of the quintessential Unix terminal emulator. It does its best
to emulate an xterm and along with that comes support for the majority of the
relevant portions of ECMA-48. This includes support for emulating varous VT-*
terminal types as well as the "linux" terminal type.
The Terminal class's VT-* emulation support is not complete but it should
suffice for most terminal emulation needs (e.g. all your typical command line
programs should work wonderfully). If something doesn't look quite right or you
need support for certain modes added please feel free to open a ticket on Gate
One's issue tracker: https://github.com/liftoff/GateOne/issues
Note that Terminal was written from scratch in order to be as fast as possible.
It is extensively commented and implements some interesting patterns in order to
maximize execution speed (most notably for things that loop). Some bits of code
may seem "un-Pythonic" and/or difficult to grok but understand that this is
probably due to optimizations. If you know "a better way" please feel free to
submit a patch, open a ticket, or send us an email. There's a reason why open
source software is a superior development model!
Supported Emulation Types
-------------------------
Without any special mode settings or parameters Terminal should effectively
emulate the following terminal types:
* xterm (the most important one)
* ECMA-48/ANSI X3.64
* Nearly all the VT-* types: VT-52, VT-100, VT-220, VT-320, VT-420, and VT-520
* Linux console ("linux")
If you want Terminal to support something else or it's missing a feature from
any given terminal type please `let us know <https://github.com/liftoff/GateOne/issues/new>`_.
We'll implement it!
What Terminal Doesn't Do
------------------------
The Terminal class is meant to emulate the display portion of a given terminal.
It does not translate keystrokes into escape sequences or special control
codes--you'll have to take care of that in your application (or at the
client-side like Gate One). It does, however, keep track of many
keystroke-specific modes of operation such as Application Cursor Keys and the G0
and G1 charset modes *with* callbacks that can be used to notify your
application when such things change.
Special Considerations
----------------------
Many methods inside Terminal start with an underscore. This was done to
indicate that such methods shouldn't be called directly (from a program that
imported the module). If it was thought that a situation might arise where a
method could be used externally by a controlling program, the underscore was
omitted.
Asynchronous Use
----------------
To support asynchronous usage (and make everything faster), Terminal was written
to support extensive callbacks that are called when certain events are
encountered. Here are the events and their callbacks:
.. _callback_constants:
==================================== ========================================================================
Callback Constant (ID) Called when...
==================================== ========================================================================
:attr:`terminal.CALLBACK_SCROLL_UP` The terminal is scrolled up (back).
:attr:`terminal.CALLBACK_CHANGED` The screen is changed/updated.
:attr:`terminal.CALLBACK_CURSOR_POS` The cursor position changes.
:attr:`terminal.CALLBACK_DSR` A Device Status Report (DSR) is requested (via the DSR escape sequence).
:attr:`terminal.CALLBACK_TITLE` The terminal title changes (xterm-style)
:attr:`terminal.CALLBACK_BELL` The bell character (^G) is encountered.
:attr:`terminal.CALLBACK_OPT` The special optional escape sequence is encountered.
:attr:`terminal.CALLBACK_MODE` The terminal mode setting changes (e.g. use alternate screen buffer).
==================================== ========================================================================
Note that CALLBACK_DSR is special in that it in most cases it will be called with arguments. See the code for examples of how and when this happens.
Also, in most cases it is unwise to override CALLBACK_MODE since this method is primarily meant for internal use within the Terminal class.
Using Terminal
--------------
Gate One makes extensive use of the Terminal class and its callbacks. So that's
a great place to look for specific examples (gateone.py and termio.py,
specifically). Having said that, implementing Terminal is pretty
straightforward::
>>> import terminal
>>> term = terminal.Terminal(24, 80)
>>> term.write("This text will be written to the terminal screen.")
>>> term.dump()
[u'This text will be written to the terminal screen. ',
<snip>
u' ']
Here's an example with some basic callbacks:
>>> def mycallback():
... "This will be called whenever the screen changes."
... print("Screen update! Perfect time to dump the terminal screen.")
... print(term.dump()[0]) # Only need to see the top line for this demo =)
... print("Just dumped the screen.")
>>> import terminal
>>> term = terminal.Terminal(24, 80)
>>> term.callbacks[term.CALLBACK_CHANGED] = mycallback
>>> term.write("This should result in mycallback() being called")
Screen update! Perfect time to dump the terminal screen.
This should result in mycallback() being called
Just dumped the screen.
.. note:: In testing Gate One it was determined that it is faster to perform the conversion of a terminal screen to HTML on the server side than it is on the client side (via JavaScript anyway).
About The Scrollback Bufffer
----------------------------
The Terminal class implements a scrollback buffer. Here's how it works:
Whenever a :meth:`Terminal.scroll_up` event occurs, the line (or lines) that
will be removed from the top of the screen will be placed into
:attr:`Terminal.scrollback_buf`. Then whenever :meth:`Terminal.dump_html` is
called the scrollback buffer will be returned along with the screen output and
reset to an empty state.
Why do this? In the event that a very large :meth:`Terminal.write` occurs (e.g.
'ps aux'), it gives the controlling program the ability to capture what went
past the screen without some fancy tracking logic surrounding
:meth:`Terminal.write`.
More information about how this works can be had by looking at the
:meth:`Terminal.dump_html` function itself.
.. note:: There's more than one function that empties :attr:`Terminal.scrollback_buf` when called. You'll just have to have a look around =)
