Documentation - Running Leo

[lewis]

In the Leo documentation at http://leoeditor.com/running.html the first line of the sub-heading says:

You can run Leo from a Python interpreter as follows:

import leo
leo.run() # runs Leo, opening a new outline or,
leo.run(fileName=aFileName) # runs Leo, opening the given file name.

Is this an old legacy option? If so it should be moved from the beginning to the end of the Running Leo documentation.
This will improve the focus for new users of Linux/Windows and not distract them with esoteric python options.
Why would someone want to run Leo this way? If there is a good reason may I suggest adding "You may want to use this method if ......."

Hope the suggestions are helpful.

Regards
Lewis

This doesn't work for me on win10 py2.7.13 or win vista python 3.5.2 if I run in a python interpreter (Idle)

>>> import leo

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import leo
ImportError: No module named leo
>>>

I may be misunderstanding something.

​It works for me. You may have to add the leo folder to Python's path.

OK thanks, added Pythonpath with variable values as my Leo folder.

The import leo command works fine. But I get a traceback with leo.run() :

​A strange one.  It works for me.

Rev 187ac6c attempts a fix.  Does it work for you?

Edward

[lewis]

Not working for me. Traceback is identical.

[lewis]

I also updated a laptop - added Pythonpath with variable values as my Leo folder.
It had the same traceback, but I haven't tried the 187ac6c commit as yet.

[lewis]

Same traceback on the laptop running commit = c84488a74ea5

Hi Edward,

I realised I was running the Python 3.6 IDLE interactive environment, which caused the errors.
Running the Python 3.6 interpreter works exactly as the Leo docs describe :)
Apologies for missing that important detail. Hope your fix hasn't caused any issues.

Regards
Lewis

​Glad to hear it.
