Unlike normal name and attribute suggestions.

I know you're using an external library to get completions for module names, so maybe this isn't possible.

The editor should have a way of telling changes using git (though using git is something you have to figure out yourself.)

When creating a new file with the "Plain Text" template, and entering a name that includes an extension (like .csv for example), that extension should probably be preserved instead of replacing it with .txt.

CFFI is an interface between Python and C - like ctypes, only better and easier to use. CFFI is largely written in pure Python, so it is possible to use CFFI with ctypes as a backend (which I've been doing for a while) but this is not officially supported. The native C backend is the officially supported way of using CFFI, and it provides some features that the ctypes backend doesn't have, such as caching parsed data type/variable/function definitions. And the native backend is probably faster than the ctypes backend.

Could we have a way to forcibly terminate a script, even if it's catching KeyboardInterrupt exceptions? I've encountered scripts in the wild that are almost impossible to stop from Pythonista.

This could, perhaps, be activated via a long press on the [x] button.

the python 2 interpreter in pythonista 3 crashes when autocompleting matplotlib commands from the editor.

#!python2
import matplotlib.pyplot as plt

Saving the file, reopening it, the.
typing plt. on the next line causes a very long wait while matplot lib is i ported by jedi. Finally, when jedi is done importing, pythonista crashes, Segmentation fault, the uncaughtexceptionhandler does not return anything.

I just think any Libs you create such as dialogs should be presented using the present func/method. Of course I think you should be able to use the new editor functions as present theme. I am guessing that these methods will be included into the present function at sometime.

I have just downloaded the app and did not see any new notification widget got added. Does anybody have this issue?

At the moment the editor module's tab support is very limited - the make_new_file and open_file functions take a new_tab argument, but there is no way to manage tabs in any other way. What should be possible:

• Getting a list of all open tabs and operating on them individually. Maybe an editor.get_tabs function that returns a list of Tab objects, which have functions of the editor module as methods that operate on that tab instead of the default one, such as get_path, get_text, annotate_line, etc.
• Getting the currently active tab as a Tab object.
• Moving and closing tabs programmatically.

In Pythonista 3 (and 2 I think) some modules do not show up in auto-complete in the editor, but they will show up in the console.

I don't know which modules. I only noticed this when trying to import pygments before.

Compare:

Verses:

When using an external keyboard, the code completions always use the standard "Menlo" font, but their size adapts to the default (user-selected) editor font, which can lead to rows in the completion list being too large or text being truncated, if the editor font has significantly different metrics.

_get_editor_tab and perhaps a few others are only directly available in the py3 editor module.

It should be possible to select multiple files in the Trash and restore or permanently delete all of them at once.

Links in the documentation and web browser should have an "Open in New Tab" option when long-pressed. And if a web browser tab is already open, webbrowser.open should make a new tab instead of replacing the existing one. (Or maybe this should be controlled by a keyword argument like with editor tabs.)

The pandas library would allow for more powerful data analysis for Pythonista, and is a much requested feature:

In the manually created table of contents for the ui module documentation, the links to ImageView and Label are listed twice.

From this forum thread: https://forum.omz-software.com/topic/3233/v2-0-vs-v2-1-hard-crash-using-reserved-var-names

Going forward to 2.1 from 2.0, I have a bunch of "hard crashes" (direct go back to ios, no error, no message) when using certain var names in my scripts (working on 2.0)

I had tracked the issue and discovered that vars names like "self.target" in scene produce 100% the crash, but using "self.Target" works.
[...]
It looks like to crash only if files had been created with 2.0 using the Game/Animation template. If the file is created with 2.1 with the template it works.

If the file is edited using Sublime Text on Mac, it works after transfer (via drop box) on iPhone
[...]
Minimal example that also crashes 2.1:

import scene
class MyScene(scene.Scene):
    def setup(self):
        self.target = scene.SpriteNode('iob:alert_circled_256', parent=self)
if __name__ == '__main__':
    scene.run(MyScene(), show_fps=False)

The implementation of these methods is completely broken in 3.0 and 2.1 (schedule and cancel_all work).

The Release Notes button in empty tabs opens the documentation panel, but doesn't show the release notes page.

The scipy library is a scientific computing library for Python. It integrates nicely with numpy, which is already included in Pythonista.

Including scipy with Pythonista would mean we'd have all the dependencies in place for the easy inclusion of lots of really powerful libraries like:

• scikit-image (advanced image processing and Computer Vision)
• scikit-learn (advanced machine learning library)

https://forum.omz-software.com/topic/2747/python-3-x-progress-update/271

a few useful sections of the Python docs are included, but not easily accessible, i. e. you need to use search or the global index to get to them.

• Complete Table of Contents - this alone would be enough, then everything would be accessible.
• Python HOWTOs - this includes things like porting to Python 3 and Unicode which are useful for people new to Python 3, but also some generally useful tutorials.
• FAQs - needless to say, those are always good to have.
• Things related to Python's C API - some things are included, some aren't. Of course those aren't of interest to the average user, but definitely useful to the non-average user trying to call the Python 2 API from Python 3 and such. :) As mentioned above, if the TOC were linked from the main page of the docs, then this would also be accessible without needing to clutter up the main page.

We discussed a Pythonista file picker a while ago in this forum thread.

@omz said:

I think this could be a useful addition to the dialogs module.

Then you came up with an awesome solution to this, but I don't think it ever got added to the dialogs module. Could you add this to dialogs?

Idea: add "show docstring", or else when using help on a non builtin, show the docstring. It might also be neat to show a "ghost" of the signature when typing a method to remind one of the arguments and ordering.

The Examples folder still contains examples of using the Notification Center widget, even though the widget was removed in the release version (for those not familiar: it was a feature that was beta-tested, but there were too many stability issues with it).

When a tab shows a file in "info" mode (with the small thumbnail, name and type description, and the "Open In"/"Edit as Text" buttons) editor.get_path() always returns None instead of the path to the file.

The file browser should have some kind of tabbing support. At the moment it's kind of annoying to work in multiple directories at once, because you need to "walk" the entire way between them by hand. Having tabs in the file browser "sidebar" might not be that useful because there's so little space, so maybe there should be a way to open a folder in a normal editor tab.

The highlighting of matches in folder names isn't cleared completely when the search bar becomes empty.

Pythonista 3.0 (300018)
iOS 8.4.1 (32-bit iPad3,3)

ui.TableView().present('sheet')

followed by closing the tab results in a crash

Objective-C exception details:

NSInvalidArgumentException: -[SUITableView_PY3 willDismiss]: unrecognized selector sent to instance 0x163ba800

App Version: Pythonista 3 (300018)
If you create two files with the same name just different extension, example is Test.py and Test.txt

They appear in the My Template section of the new file screen as the same name so you don't know which one is which.

Is it possible to show file extensions in the file screen? Either as test.py or the file extension as the detail line of the cell just below to main label?

When typing _ as a name or attribute, the completion list disappears, even if there are names/attributes that start with _. Other combinations, such as __, work fine.

When you slide to select all (or a big chunk of) text in the console when in split screen (half or 1/3), the actual selection works but the blue selection display is buggy. I've attached a photo of this:

https://forum.omz-software.com/topic/3240/asyncio-doesn-t-work-in-pythonista-3

loop = asyncio.get_event_loop()
loop.close()  # this will throw a RuntimeError on subsequent runs until Pythonista 3 is rebooted

RuntimeError: There is no current event loop in thread xxx

Workaround: Don't call loop.close()
@jsbain workaround: loop = asyncio.get_event_loop_policy().new_event_loop()

The editor takes a while to load large files, and it has some performance issues with very long lines. There should perhaps be a warning before opening a file that either exceeds a certain size, or has at least one line longer than a certain number of characters.

https://forum.omz-software.com/topic/2747/python-3-x-progress-update/362

when editing an already typed line, the autocompletion often inserts extra parens before an existing function call. For example, say I have this line of code:

mylist.append("foo")

Then I decide I want to use insert instead. I double-tap append, type ins, and hit Enter Tab to accept the suggestion. The output I get is

mylist.insert()("foo")

In this case I would expect it to detect the existing parens and not add extra ones.

(But hopefully the entire extended keyboard can just always be hidden when there is a BT keyboard active)

Pythonista uses 2.7.5 (released on 2013-05-15), the current latest version is 2.7.11 (released on 2015-12-05), and 2.7.12 is coming soon (planned on 2016-06-25, that's next week!). Might be good to update to 2.7.12 once that comes out.

It would be nice to allow placeholders for the current date/time in user-created file templates.

I'm not sure how exactly this should be implemented (i.e. what format to use for different date formats etc.), or if there are things other than the current date that should be considered as possible placeholders in templates.

Support for cryptography would be nice so we can work with higher level encryption methods that are easier to use and secure unlike Crypto which is only low level. Also this gives us the ability to use PyOpenSSL for working with certificates.

Currently the two attributes do not exist, and when setting them the interactive console does not respect them and always displays the standard prompts instead.

https://forum.omz-software.com/topic/1946/pythonista-1-6-beta/63

For example, behind print( and mystr + completions appear correctly, but not behind os.listdir( or os.sep +

This has been undocumented for a long time.

Invoking the "Help…" menu from the editor in version 2.1 always shows "no results", regardless of what's selected.

When completing something like @prop, it should become @property and not @property().

sys.stdin, sys.stdout and sys.stderr do not have isatty or fileno methods, which are required by some command-line scripts. isatty should probably return True (the console is interactive and has limited terminal-like features) and fileno should return 0, 1 and 2 respectively (the file descriptors of the real standard streams).

It'd be awesome if OpenCV could be compiled for Pythonista. There are existing Python bindings in the cv2 module, and also Objective-C bindings. I don't know how difficult it would be to get this working on Pythonista, but it would certainly allow for some impressive applications.
