<title>Wily/Python Interface
<author>
<htmlurl url="http://www.cs.su.oz.au/~gary/" name="Gary Capell">
<date>v0.11.0 April 1996
<abstract>
This document describes the Python interface to <htmlurl
url="http://www.cs.su.oz.au/~gary/wily/" name="Wily">, which
is implemented in <tt/wilymodule.c/. It defines three classes:
<tt/Connection/, <tt/Win/ and <tt/Event/. A <tt/Connection/ is
initialized with no arguments, and represents the connection to Wily.
A <tt/Win/ object is created by the <tt/Connection/, and is usually
initialized with the name for a new window. The <tt/Connection/ has
methods to return a list of windows representing all the windows
currently open at Wily, to create a new window, and to return the next
<tt/Event/ from Wily. A <tt/Win/ has methods to change its event mask,
name or ``tools'' (useful text in the window's tag), read or modify
some of its text, or simulate a B2 or B3. <tt/Event/ objects have
attributes to identify the window to which they refer, the event type,
and other optional attributes depending on the event type. B2 and B3
events include the text selected, and where it was located in the text.
Text modifying events indicate where the change took place, and what
new text was added. See also the <htmlurl url="msg.html" name="Wily
Messaging Interface"> for C programs, the <htmlurl url="user.html"
name="Wily User's Guide"> and <htmlurl url="pythonpaper.ps"
name="Wily+Python>Emacs+Lisp"> This document is also available in
<htmlurl url="python.ps" name="Postscript">.

<verb>

<sect1>Attributes

<sect1>Methods<P>
<descrip>
<tag/win(name)/
Returns a new window, with the given <tt/name/
<tag/list()/
Returns a list of <tt/win/s representing the windows currently open in
wily.
<tag/event()/
Returns the next Event. Note that this function will block until it receives
an event.
<tag/event_wouldblock()/
Indicates whether <tt/event()/ would block.
</descrip>
<sect>win<P>
<sect1>Creating<P>
<tt/win/ objects are returned by <tt/connection.win(name)/ or
as part of <tt/connection.list()/
<sect1>Attributes<P>
<descrip>
<tag/id/
window id
<tag/name/
name
<tag/dot/
a (from,to) tuple representing the currently selected portion of the
window.
</descrip>
<sect1>Methods<P>
<descrip>
<tag/attach()/
Request events for this window.
<tag/detach()/
Cancel request for events for this window.
<tag/setname(s)/
Set the name of this window.
<tag/settools(s)/
Set the toolbar for this window.
<tag/read((from,to))/
Read some range from this window.
<P>Called with a tuple representing the range to read, returns a UTF
string.
<tag/replace((from,to),s)/
Replace some range of window with some other text.
<P>Called with a tuple representing the range to replace, and a string
to replace it with. Insertion and deletion are special cases of
<tt/replace/, with null range or replacement string respectively.
<tag/run(s)/
Execute some text in this window. Makes wily act as if <tt/s/ had
been selected with button 2 in this window. This can be used to
access Wily's built-in functions. For example, to delete <tt/w/, call
<tt/w.run("Del")/
<tag/goto(s)/
"Goto" some text in this window. Makes wily act as if <tt/s/ had been
selected with button 3 in this window. This can be used to open a new
window, or search for some regular expression. Returns a <tt/win/ if the
Goto resulted in a successful search in this window.
