One new file in the attached, PyParse.py. The LineStudier (whatever it was
called <wink>) class was removed from AutoIndent; PyParse subsumes its
functionality.
Removed "New tabwidth" menu binding.
Added "a tab means how many spaces?" dialog to block tabify and untabify. I
think prompting for this is good now: they're usually at-most-once-per-file
commands, and IDLE can't let them change tabwidth from the Tk default
anymore, so IDLE can no longer presume to have any idea what a tab means.
Irony: for the purpose of keeping comments aligned via tabs, Tk's
non-default approach is much nicer than the Emacs/Notepad/Codewright/vi/etc
approach.
2. No longer need to reset pyclbr cache and show watch cursor when calling
ClassBrowser -- the ClassBrowser takes care of pyclbr and the TreeWidget
takes care of the watch cursor.
3. Reset the focus to the current window after error message about class
browser on buffer without filename.
I'm still unsure, but couldn't stand the virtual event trickery so tried a
different sin (adding undo_block_start/stop methods to the Text instance in
EditorWindow.py). Like it or not, it's efficient and works <wink>. Better
idea?
Give the attached a whirl. Even if you hate the implementation, I think
you'll like the results. Think I caught all the "block edit" cmds,
including Format Paragraph, plus subtler ones involving smart indents and
backspacing.
[W]hile trying to dope out how redirection works, stumbled into two
possible glitches. In the first, it doesn't appear to make sense to try to
rename a command that's already been destroyed; in the second, the name
"previous" doesn't really bring to mind "ignore the previous value" <wink>.
You can switch database by just loading the new one; the list window
and nearest colors adapt to the new database.
Some reorganizing of code. Also, the name of the database file is
stored in the ~/.pynche pickle. If it can't be loaded, fallbacks are
used.
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
