Re: Seeking feedback from speech users of Python

Thanks for the feedback, Jim.

An advantage of PyBrace over beeps or words that indicate a change of
indentation is that a comment is automatically generated that indicates
what code block has closed.  Thus, one does not have to recall that a
"while" was two beeps in and and "if" was one beep.

Yes, in EdSharp, Alt+Home goes to the first nonblank character of a line,
and indeed, its purpose is to skip over indentation.  Home without the Alt
modifier key is just easier and more habitual to press, and the purpose of
PyBrace is to maximize usability for a speech and keyboard user.

Regarding space versus tab for indentation, does one work better when JAWS
displays a web page with the virtual buffer?  Richard has reported that
some Python code loses its indentation in this mode, whereas other
indentation is preserved.  Obviously, preserving it is important when
reading Python code on the web.  I was guessing that a tab character was
more likely to be preserved than a space, so that was partly why I chose
it ininitially, but I was guessing there.  To me, tab also makes more
sense logically because a single tab character can be used rather than
multiple spaces, and the user can often adjust the display width of a tab
character in his or her editor.  I do recall, however, that Perl style
guidelines recommend spaces (4) and Ruby's recommend them as well (2),
so it does not surprise me that Python guidelines have developed
similarly.  I will probably make EdSharp use whatever the user has set for
the IndentationUnit in the configuration dialog.

To what extent do you use braille when programming in Python?
