there are two new commands:
Import module (F5) imports or reloads the module and also adds its
name to the __main__ namespace. This gets executed in the PyShell
window under control of its debug settings.
Run script (Control-F5) is similar but executes the contents of the
file directly in the __main__ namespace.
idle.py -e file ... -- to edit files
idle.py script arg ... -- to run a script
idle.py -c cmd arg ... -- to run a command
Other options, see also the usage message (also new!) for more details:
-d -- enable debugger
-s -- run $IDLESTARTUP or $PYTHONSTARTUP
-t title -- set Python Shell window's title
sys.argv is set accordingly, unless -e is used.
sys.path is absolutized, and all relevant paths are inserted into it.
Other changes:
- the environment in which commands are executed is now the __main__ module
- explicitly save sys.stdout etc., don't restore from sys.__stdout__
- new interpreter methods execsource(), execfile(), stuffsource()
- a few small nits
dramatically (up to 15 times he claims). Works by reading more than
one line at a time, up to 100-line chunks (starting with one line and
then doubling up to the limit). On a typical machine (e.g. Tim's
P5-166) this doesn't reduce interactive responsiveness in a noticeable
way.
unsuccessful search wraps around and re-searches that part of the file
between the start of the search and the end of the file - only really
an issue for very large files, but... (also removes a redundant
m.span() call).
o Makes the tab key intelligently insert spaces when appropriate (see Help
list banter twixt David Ascher and me; idea stolen from every other editor
on earth <wink>).
o newline_and_indent_event trims trailing whitespace on the old line (pymode
and Codewright).
o newline_and_indent_event no longer fooled by trailing whitespace or
comment after ":" (pymode, PTUI).
o newline_and_indent_event now reduces the new line's indentation after
return, break, continue, raise and pass stmts (pymode).
The last two are easy to fool in the presence of strings & continuations,
but pymode requires Emacs's high-powered C parsing functions to avoid that
in finite time.
pyclbr.Class object; this can happen when the superclass is
unrecognizable (to pyclbr), e.g. when module renaming is used.
- Show a watch cursor when calling pyclbr (since it may take a while
recursively parsing imported modules!).
directories on sys.path
modules in selected directory
classes in selected module
methods of selected class
Sinlge clicking in a directory, module or class item updates the next
column with info about the selected item. Double clicking in a
module, class or method item opens the file (and selects the clicked
item if it is a class or method).
I guess eventually I should be using a tree widget for this, but the
ones I've seen don't work well enough, so for now I use the old
Smalltalk or NeXT style multi-column hierarchical browser.
with changed APIs -- it makes much more sense there.
Also add a new feature: if the first character of a menu label is
a '!', it gets a checkbox. Checkboxes are bound to Boolean Tcl variables
that can be accessed through the new getvar/setvar/getrawvar API;
the variable is named after the event to which the menu is bound.
