[issue37903] IDLE Shell sidebar.
Stephen Paul Chappell added the comment:
Zero: "not to have them added as text as is usual in a terminal window"
taleinat: "removing prompts from the shell window's text widget"
Zero: "print the values of ps1 and ps2 in the proposed ShellIO subclass"
taleinat: "separate sidebar showing where prompts and user input were"
We appear to be in agreement.
terry.reedy: "Labels, such as '>>>', 'Out', 'Inp', and 'Err' would be used"
Zero:"Having IDLE react to sys.ps1 and sys.ps2"
My suggestion is to take those labels terry.reedy talks about from the values
of ps1 and ps2 since they are already documented and standard for "the
interpreter ... in interactive mode." If psX needs to introduced for other
prompts that may be needed ("Maybe use 'Con', maybe use Dbg and Wrn."), it
would provide a sensible way to customize those labels as well.

[issue37903] IDLE Shell sidebar.
Stephen Paul Chappell added the comment: Maybe my impression has been false this whole time, but the Python interactive interpreter seems to be very similar to the IDLE shell window. My question is, "Why not make them even more so?" Having IDLE react to sys.ps1 and sys.ps2 opens up the shell to similar use cases as having them defined in the interactive interpreter. My suggestion is not to have them added as text as is usual in a terminal window but to print the values of ps1 and ps2 in the proposed ShellIO subclass. That would make label customization possible in a way that is already documented and standard. -- ___ Python tracker <https://bugs.python.org/issue37903> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue37903] IDLE Shell sidebar.
Stephen Paul Chappell added the comment:
The documentation for sys.ps1 and sys.ps2 states that they "are only defined if
the interpreter is in interactive mode." Since the IDLE shell is meant to be
interactive (and to reduce the differences between the shell and running Python
directly), would it be helpful if ps1 and ps2 were defined when running IDLE?
The shell could then honor their values.
If such a direction was explored, one issue may be that the sidebar could not
simply be 3 char wide. The documentation also states that non-strings are
evaluated each time they are needed by the interpreter. This allows for such
interesting possibilities as shown with the code below but may not be desired
functionality for the IDLE shell window.
import sys
from datetime import datetime
class TimePrompt:
def __init__(self, prefix, suffix):
self.prefix, self.suffix = prefix, suffix
def __str__(self):
return f'{self.prefix}{datetime.now()}{self.suffix}'
sys.ps1, sys.ps2 = TimePrompt('', ' >>> '), TimePrompt('', ' ... ')

[issue38636] IDLE regression: toggle tabs and change indent width functions
Stephen Paul Chappell added the comment: When I start IDLE and the shell window appears, my first task is to press "Alt + T" to change from using tabs to spaces and then "Alt + U" to change from using 8 spaces to 4. This allows code pasted from the shell into an editor window or other IDE to not require reformatting since those settings seem to be common for Python code. If the defaults for these settings were to be exposed in IDLE's settings under the General tab (maybe near the new "Show line numbers in new windows" checkbox), would it be best to make that request here or to open a new bug with an enhancement suggestion? -- ___ Python tracker <https://bugs.python.org/issue38636> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue31848] "aifc" module does not always initialize "Aifc_read._ssnd_chunk"
New submission from Stephen Paul Chappell <noctis.skyto...@gmail.com>: When Aifc_read runs initfp, it conditionally sets self._ssnd_chunk and is not guaranteed to do so. At the bottom of the method, a check is made to see if the attribute has a false value; and if so, an error is supposed to be raised.

[issue31476] "Open Module..." Not Working in IDLE for Standard Library
New submission from Stephen Paul Chappell: Ever since Python 3.6.1, trying to open a Python-source library module in IDLE on Windows (10) has not worked properly since the installer has only been providing *.pyc files. Learning how to use Python has always been easy since it (1) has a great help document, (2) makes it easy to get help() on objects, and (3) allows the source to easily be explored and/or patched. Is there something special that needs to be done to get both the standard library's *.py files and precompile them to *.pyc during installation? I would be glad to run further tests if the Windows installer can be run headless with specific command-line arguments. -- assignee: terry.reedy components: IDLE, Library (Lib), Windows messages: 302201 nosy: Zero, paul.moore, steve.dower, terry.reedy, tim.golden, zach.ware priority: normal severity: normal status: open title: "Open Module..."

New submission from Stephen Paul Chappell: In the string module, the definition of whitespace is ' \t\n\r\v\f'. However, the representation of string.whitespace is ' \t\n\r\x0b\x0c'. Would it be terribly inconvenient to change the representation of '\x0b\x0c' to '\v\f'?

[issue18558] Iterable glossary entry needs clarification
Stephen Paul Chappell added the comment: Maybe this would have been more appropriate as a question on StackOverflow: What is the proper way of asking if an object is iterable if it does not support the iterator protocol but does support the old getitem protocol? One might argue that it is better to ask for forgiveness rather than permission, but that does not really answer the question. My impression of collections.abc.Iterable is that programmers can use it to ask if an object is iterable. Some argue that it is better to ask for forgiveness rather that permission and would suggest pretending that an object is iterable until it is proven otherwise. However, what do we use collections.abc.Iterable’s for then? The true question is really, “What is the proper way of asking if an object is iterable if it does not support the iterator protocol but does support the old getitem protocol?” More generically, how can you ask an object if it supports ANY iteration protocol? The query probably should have been posted on StackOverflow and not here. This may not be a problem with collections.abc.Iterable, and thus the issue should be closed. However, the previous question remains, and it is apparent that it cannot be answered with the abstract class as it currently is. Maybe the solution is to just ask for forgiveness where appropriate. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18558 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
