The new version (attached) is fast enough all the time in every real module
I have <whew!>. You can make it slow by, e.g., creating an open list with
5,000 90-character identifiers (+ trailing comma) each on its own line, then
adding an item to the end -- but that still consumes less than a second on
my P5-166. Response time in real code appears instantaneous.
Fixed some bugs.
New feature: when hitting ENTER and the cursor is beyond the line's leading
indentation, whitespace is removed on both sides of the cursor; before
whitespace was removed only on the left; e.g., assuming the cursor is
between the comma and the space:
def something(arg1, arg2):
^ cursor to the left of here, and hit ENTER
arg2): # new line used to end up here
arg2): # but now lines up the way you expect
New hack: AutoIndent has grown a context_use_ps1 Boolean config option,
defaulting to 0 (false) and set to 1 (only) by PyShell. Reason: handling
the fancy stuff requires looking backward for a parsing synch point; ps1
lines are the only sensible thing to look for in a shell window, but are a
bad thing to look for in a file window (ps1 lines show up in my module
docstrings often). PythonWin's shell should set this true too.
Persistent problem: strings containing def/class can still screw things up
completely. No improvement. Simplest workaround is on the user's head, and
consists of inserting e.g.
def _(): pass
(or any other def/class) after the end of the multiline string that's
screwing them up. This is especially irksome because IDLE's syntax coloring
is *not* confused, so when this happens the colors don't match the
indentation behavior they see.
Ho ho ho -- that's trickier than it sounded! The colorizer is working with
"line.col" strings instead of Text marks, and the absolute coordinates of
the point of interest can change across the self.update call (voice of
baffled experience, when two quick backspaces no longer fooled it, but a
backspace followed by a quick ENTER did <wink>).
Anyway, the attached appears to do the trick. CPU usage goes way up when
typing quickly into a long triple-quoted string, but the latency is fine for
me (a relatively fast typist on a relatively slow machine). Most of the
changes here are left over from reducing the # of vrbl names to help me
reason about the logic better; I hope the code is a *little* easier to
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
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.
Much has changed -- too much, in fact, to write down.
The big news is that there's a standard way to write IDLE extensions;
see extend.txt. Some sample extensions have been provided, and
some existing code has been converted to extensions. Probably the
biggest new user feature is a new search dialog with more options,
search and replace, and even search in files (grep).
This is exactly as downloaded from my laptop after returning
from the holidays -- it hasn't even been tested on Unix yet.
