Re: cell execution inbetween ## delimters

[David]

If you select the region of code you want to run, then press F9, it will be executed.

I believe this was done in response to previous requests for a cell mode in spyder, and should be good enough for most purposes. If you really need cell mode for python code, then consider using the IPython notebook (http://ipython.org/)

Dear all,

Is there any way to get spyder to execute code in blocks marked off by a delimiter. For example a double quote ##?

Thanks a lot,
Mark

Hi, 

I think that Mark's proposal is interesting. One could give the choice between delimiters "##" and "# <codecell>" which is the default delimiter when exporting an ipython notebook as a python script.

A very short change that does it in spyderlib/widgets/sourcecode/mixins.py, from line 186: 

        def _is_separator(cursor):

            cursor0 = QTextCursor(cursor)

            cursor0.select(QTextCursor.BlockUnderCursor)

-            text = unicode(cursor0.selectedText())

-            return len(text.strip()) == 0 or text.lstrip()[0] == '#'

+           text = unicode(cursor0.selectedText()).lstrip()

+           return text[:2] == '##' or text[:12] == '# <codecell>'

What do you think of it?

Opened issue 1292 regarding this.

I've been thinking to use

# %%

instead of

##

as cell markers, for two reasons:

1. It'd be far more easier to parse.

2. We could combine them with IPython cell magics, like this:

# %%timeit
print 'foo'

Cheers,
Carlos

However, it can be interesting to keep the "# <codecell>" delimiter as it is the standard delimiter when exporting from an ipython notebook.

Yeah, that would be fine too, but no '##', that would be a nightmare to make it work right :-)

Absolutely. Another argument against '##' is that PEP 8 recommend that inline comment should start with # and a single space. 

Editor such as Eclipse will break all '##' into '# #'... http://www.python.org/dev/peps/pep-0008/

Best,
