StaSh for Pythonista 2 and 3

ywangd

@JonB Dulwich supports at least to Python 3.4 But Gittle has no Python 3 support. Any idea how the git tools could be ported to Pythonista 3?

The python-future project has an experimental feature to automatically translate Python 2 modules to Python 3 upon loading. But I am not sure how reliable it is.

The main framework of StaSh is working now. I am in the process to make sure all the commands still work. I have ran git through some 2to3 tools so itself is now mostly Python 3 compatible. But the dependencies could be the tricky part.

I guess I can start removing gittle dependancies (right after I finish the gh command, which is almost ready)

Much of gittle is superceeded by dulwich porcelain, or workarounds in my own code. I have been itching to rewrite git from scratch for a while anyway. my newfound discovery of docopts will make much of the CLI interface easier, the trickier bit is whether it makes more sense to update dulwich, or git.

Guys, time for a new thread for StaSh Pythonista 3.x?

ywangd

@Phuket2 @JonB I think we should have a separate thread for the git tools. With the main post being some instruction, tips for best practice/workflow to help out many common issues. We can then discuss about porting and other improvements in the new thread.

@ywangd I've just installed Stash. How do I cd to the Home directory? I'm not familiar with the iPad file system.

"Please run launch_stash.py under the Home directory to start StaSh."

JonB

The best way to run stash, is to click the wrench icon, then edit, then the plus sign. then find the launch_stash file.

Then, you will have a shortcut in the wrench menu that you can run anytime.

ywangd

@cappy The launch_stash.py file is found in the directory when you start Pythonista, i.e. Documents.

From Pythonista's file browser (swipe to right to reveal it if not already visible), select launch_stash.py. This opens the file in the editor, then click the Run button (the right-facing triangle on the top right) to start StaSh.

Once you know where the launch file is, you can create an editor action to access it quickly as @JonB suggested.

I just typed 'git' into stash and got this, looks similar to something posted in here earlier...I'm so confused.

@Tizzy your stash is v0.4.0 but the current version is v0.6.0.

ywangd

@Tizzy It is recommended to install the latest version of StaSh (0.6.3). Version 0.5 and up is not compatible with 0.4 and lower. So please delete your current 0.4 installation and run the following oneliner to get the latest release:

import requests as r; exec r.get('http://bit.ly/get-stash').text

Once installed, restart Pythonista and run launch_stash.py under Documents to start.

@ywangd , sorry I am at a total loss.its really mixed up here. About Pythonista 2/3

I do in Pythonista 3
import requests as r; exec r.get('http://bit.ly/get-stash').text
In Python 3,
I get

import requests as r; exec r.get('http://bit.ly/get-stash').text
File "<string>", line 1
import requests as r; exec r.get('http://bit.ly/get-stash').text
^
SyntaxError: invalid syntax

dgelessus

The line should really be

import requests as r; exec(r.get('http://bit.ly/get-stash').text)

Note the parentheses around the argument to exec. In Python 2 exec was a special statement and did not require parentheses like a normal function. In Python 3 exec was changed to a normal function (just like print) so now you need parentheses to call it. In Python 2 exec can also be used like in Python 3 (see the language reference for the details) so the Python 3 style is what you should use in almost all cases.

@dgelessus , I still get an error

import requests as r; exec(r.get('http://bit.ly/get-stash').text)
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "<string>", line 18
print 'Downloading %s ...' % URL_ZIPFILE
^
SyntaxError: Missing parentheses in call to 'print'

But I can see there is a problem with the print. But it's part of an install, not sure I can do anything about that

dgelessus

Uh @ywangd is there a different download link for the py3 branch?

@dgelessus @ywangd So it's interesting that Stash runs in its own tab, presumably on its own thread, and closing the tab kills the thread?

How do you implement this in pythonsta for other scripts? (this would solve the only being able to run a single script limitation)

ALSO, I appreciate the confirmation before downloading stuff in this version... in that last one simply typing something would try to download it.

ALSO bug report, sometimes the keyboard goes black except the top row with "tab, ~, "etc...

ywangd

@Phuket2

For Pythonista 3, there is a separate branch and following oneliner installs it (note it uses a different url for the py3 branch):

import requests as r; exec(r.get('http://j.mp/gsp35').text)

@Tizzy
StaSh uses threads to run commands users type in the terminal. The thread is killable and when StaSh UI is closing, it kills all the threads it spawned. With current version, you can already run multiple scripts with StaSh at the same time. Here is an example that a http server and client runs together. Details of the killable threads can be found in the shthreads.py file.

in that last one simply typing something would try to download it.

I don't quite understand it. Do you mean that pip and git download their dependancies?

ALSO bug report, sometimes the keyboard goes black except the top row with "tab, ~, "etc...

The extra key row is something I wanted to re-write since 2.0 came out. Just didn't have the time. I'll work on it when time permits.

@ywangd , thank you. Successfully downloaded it
