Re: txtorcon 23.5.0

[Benjamin Schollnick]

Meejah,

Sorry, but, would you please consider adding a short description to this of 
what txtorcon is.
It’s great that your announcing the update, and highlighting the changes…if I 
used it, I’d be upgrading it.

But I have absolutely no idea why I would want to investigate using it, because 
there is no description of the package.

Well, that’s not 100% true.  From my knowledge of twisted, I know it’s network 
based, and that’s it.  I can’t tell if it’s a server, or client application.

Even just simply adding your 10,000 feet summary:

txtorcon is an implementation of the control-spec 
 for Tor 
 using the Twisted 
 networking library for Python 
.

would have been extremely helpful.

I hope you will take this as the creative criticism that I am offering it as.  

- Benjamin

Looks like you are using IDLE? If so, it's possible that in the original
case you had some values set from a previous run that were picked up but
when you reimport later those values are missing. It would help if you
can post any error messages since they should give clues(like name
errors for example).

Also describe how you are "importing" the modules. are you typing

>>> import mymodule

at the interactive prompt or are you using the File->Open menu
to load them into the editor? (It sounds like the latter)

reimport is not 100% reliable, in simple cases it will work, but as your
code gets more complex it can break.

I rarely use reimport. Usually just exit python and start again.

If you are working on scripts then just run them from the Terminal
will work well with any need to use reimport.

You can download the release from PyPI or GitHub (or of

https://pypi.python.org/pypi/txtorcon/23.5.0
https://github.com/meejah/txtorcon/releases/tag/v23.5.0

as well as this -

at the moment my code is very minimal, one saved piece is a nice one-liner that 
I kept because I wanted to remember syntax and how easy/elegant "some" things 
are in python, but if I import it it fails

>I rarely use reimport. Usually just exit python and start again.

I may have confused this I use import to get my saved work, the "re" was to 
shoe it had been saved by the editor

In that case, yes, because the conversion did not depend on what was originally

And that’s the point, if you want to me to consider your package, I should have 
some idea that it’s worth me investing more time into seeing if it can help me. 
 As I mentioned simply stating that it was a “Tor Control management API” would 
have been enough for me to say “That’s not helpful to me”.  On the other hand 
if it said “Django management API/Tool”, I would have gone to the git 
repository and investigated.

Effectively, posting a release notification is an advertisement for the 
package, as well as a notice saying “Here’s some updates”.

When done correctly, it can bring more people to use your package / software…

This has nothing to do with package managers, this has to do with “Why should I 
use this package” or “Should I use this package / software”.  If the release 
notes are being send to people that don’t already have the package then it’s 
worth the couple of sentences or a short paragraph to allow someone that is 
unfamiliar with the package to be able to see if they should investigate the 
package.

Cryptic names maybe cute, but if they are not descriptive, then they are not 
really that helpful other than being unique.

Is there an alternate path to installing this?

Usually tkinter ships with Python because it is part of the stdlib.

On some platforms eg Ubuntu Linux the stdlib doesn't come in completely
unless you ask - a lot of stdlib packages are apt things you need to ask
for. On my Ubunut here tkinter comes from python3-tk. So:

  $ sudo apt-get install python3-tk

And in general, on Linux systems, you'll be better off in the long run
if you use the distro's package manager to install Python packages
instead of using pip. If there is no distro package, you're usually
also better off using 'pip install --user' so that pip isn't messing
about with directories that are normally managed by the distro's
package manager.

When I do have to resort to using pip in install something, I always
do a --dry-run first and make a note of any dependancies that pip is
going to try to install -- so I can install those using the package
manager if possible.

Great suggestion! I didn't know that --dry-run was available... I'll

You imported cube but tried to use cubes. I'm guessing
cubes is defined inside cube so you would need

cube.cubes

cubes looks like it should be a function but in that case there
should be parens after it. So I'm not sure how that is working!

I'd expect that you need to do:

import cube
cube.cubes()
