Guido van Rossum 54f22ed30b More trivial comment -> docstring transformations by Ka-Ping Yee,
who writes:

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.

I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.

The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings.  Hope this is
okay.

I regularly find that pdb sets the breakpoint on the wrong line when I
try to set a breakpoint on a function.  This fixes the problem
somewhat.
The real problem is that pdb tries to parse the Python source code to
find the first executable line.  A better way might be to inspect the
code object, or even have a variable in the code object
co_firstexecutablelineno, but that's too much work.

The patch fixes the problem when the first code line after the def
statement contains the start *and* end of a triple-quoted string.  The
code assumed that the end of a triple-quoted string is not on the same
line as the start, and so it would skip to the end of the *next*
triple-quoted string.

Barry Warsaw 2bee8feac6 Pdb.lineinfo(): Don't use os.popen('egrep ...') to find the line in
the file that a function is defined on.  Non-portable to Windows and
JPython.  Instead, new find_function() uses re module on a similar
(simple-minded) pattern.

Guido van Rossum b657c9344f Improvement of b/w compat note in help text for clear, by Richard Wolff. 1999-01-28 14:38:32 +00:00
Guido van Rossum 583cc31c22 Get rid of do_clear_break / do_clb command -- it is redundant.
(It was left in accidentally after a long and arduous 3-way patch session.)

Guido van Rossum 816a9fbd2c Change clear syntax to support three alternatives:
clear
    clear file:line
    clear bpno bpno ...

Also print the breakpoint data after calling set_break(), because the
print statement in set_break() has gone.

Guido van Rossum c2047c19f5 When run as a script, don't pass a fake __main__ dictionary; use the
real one.

Guido van Rossum 3a98e78a6e Richard Wolff's additional changes; some layout nits, and change the
alias delimiter to ';;'.

Guido van Rossum 2424f855f3 Richard Wolff's changes:
pdb.py  Uses the Breakpoint class so one can enable/disable breakpoints,
	set temporary ones, set ignore counts, and conditions.  The last
	can be set using the 'b' command
		b 243 , i>4		( b 243,i>4 if you are space adverse)
	or with the condition command so conditions can be changed
	for a particular breakpoint.

	Breakpoints are numbered from 1 on, and if a breakpoint is deleted,
	the number is not reused.  All the breakpoint handling commands
	refer to breakpoints by number.  To be consistent, the clear command
	does so as well, which is the one change from the original pdb that
	is not transparent.  Thus only the breakpoint command 'b' uses a
	line number or file:line or method.  You can also give
		b whrandom.random    and the method will be searched for along
	sys.path.  This is implemented with an 'egrep' command and so
	is not as portable as it might be.  [ see  lineinfo() and
	lineinfoCmd ]

	Breakpoints cannot be set at a line that is blank or a '#' comment
	or starts a triply quoted comment.  This is because I would like
	this behavior in my DDD interface and think it reasonable for
	pdb as well.  It can be removed readily, however as it is all
	incorporated in the routine checkline().  If one attempts to
	set a breakpoint at a 'def' line, the breakpoint is automatically
	moved to the first executable line after the 'def'.  This too is
	in checkline().

	do_EOF() returns zero so typing an end-of-file character as a command
	does nothing.  'quit' does the quitting.

	The routine defaultFile() is present so as to preserve the current
	pdb behavior and yet allow me to override it in pydb.

	There's some code in lineinfo() that is probably mainly useful only
	for pydb and if you prefer, much up to the comment "Best first guess"
	could be removed.

	Keith Davidson provided the code for handling $HOME/.pdbrc and
	./.pdbrc, and it has been incorporated.  He also provided the
	alias handling routine.  I modified it a bit so it could live
	nicely in precmd().  He and I have been in contact; he has the
	new pdb (and pydb) with his code incorporated.  He also asked
	about the possibility of allowing multiple commands on one
	line, such as step;step  or s;s  or with an alias such as
		alias ct tbreak %1 ; continue
	and since it was so easy, that's in place as well.  It's a simple
	'split the line at the first ";"' operation and puts the second
	half in the command queue (self.cmdqueue).  This has the unfortunate
	effect of destroying a line like   print "i: "+i+"; j: "+j
	but either there's a simple way to deal with this, or my attitude
	will remain that pdb is a debugger, not a compiler/parser/etc.
	An alias like   alias 4s  s;;s;
	will work because the adjacent and trailing ";" act like a <cr> which
	repeats the last command.  Of course, either s;s;s;s or s;;;  would be
	a bit more sensible.

	The help commands have been updated.

Guido van Rossum 1f00eed8b5 Feature added by Harri Pasanen (at my suggestion): .py suffix on
filename may be omitted.
1998-07-22 13:35:21 +00:00
Guido van Rossum b5699c7240 Added support for specifying a filename for a breakpoint, roughly
according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions.  Also added a helper method lookupmodule().

Also:

- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.

Guido van Rossum 46c86bbca9 A working version of the 'args' command (it prints the current values
of the variables known to hold arguments, but that's as close as I can
get, and generally it's close enough).
