prompt-toolkit / ptpython Goto Github PK

Hi, in this screenshot it looks like ptpython is hinting the argument list to the currently typed function. I've been playing around with ptpython and am unable to trigger this feature. So, two questions -- How do I enable function hinting in ptpython, and second, where/how is the hinting accomplished in the source code?

Thanks!

installed with pip as recommended on your page. Trying to run:

There seems to be no way to switch python versions for ptpython. I have 2.7 and 3.4 installed concurrently. If I use pip I can reinstall whichever one i need to use and it'll work that way, but then I have to use pip every time I need to switch. Is there a better way to handle this?

This looks like a very interesting project. However, from reading the README, some things remained unclear for me, so maybe you can clarify that in the README?

• What exactly are the differences to IPython?
• Does it have a web frontend? Or any other graphical frontend?
• Does it work together with IPython QtConsole or IPython Notebook?

when I use ptpython in cygwin I get this symbols [13;1R in the prompt

$ ptpython
In [1]: [13;1R

It feels like the matplotlib integration (which runs in a separate event loop) is a bit broken by ptipython, this will probably be a problem for anyone using matplotlib.

I'm using Linux Mint 17.1 (Ubuntu 14.04), Python 3.4.2 (Anaconda), IPython 2.2.0, today's <master> for ptipython.

If I run this in either ipython or ptipython, the plt.show() correctly causes a graph window to be drawn:

In [1]: import matplotlib.pyplot as plt
In [2]: plt.plot([1,2,3])
Out[2]: [<matplotlib.lines.Line2D at 0x7f04cd208278>]
In [3]: plt.show()  <-- graph window gets drawn

If the above (lines 2 & 3) are repeated in either ipython or ptipython, the graph will show again (so it feels like matplotlib integration is working in ptipython).

Note that in this mode (without using %matplotlib or passing in --pylab) the .show() is blocking.

If I run a vanilla ipython (i.e. $ ipython, not $ ipython --pylab), the %matplotlib magic works and the event-loop is non-blocking. This is the usual interactive development process if you're working with charts:

In [1]: %matplotlib
Using matplotlib backend: Qt4Agg

In [2]: import matplotlib.pyplot as plt

In [3]: plt.plot([1,2,3])
Out[3]: [<matplotlib.lines.Line2D at 0x7f2adff4bef0>]  
<-- graph windows pops up, no need to call plt.show(), interactive prompt is still interactive

If I run the same using $ ptipython, I don't get a graph window. If I add plt.show() then I also don't get a graph window. It looks like the matplotlib integration is a bit broken.

Some (possibly unhelpful) notes:

• https://carreau.github.io/posts/10-No-PyLab-Thanks.ipynb.html
• http://matplotlib.org/users/shell.html

I'll also note that autocompletion on e.g. plt.plot( gets slow, this is a Jedi problem (and Rope too) with matplotlib, scipy etc and has been noted in e.g. the GVim forums. Somebody is bound to mention this soon so you ought to be aware of it.

I makes Completion menu into toolbar, but when I close session, It turns back to the original.

Maybe It should be user-configurable.

Hello. I've got a problem with "Execute" (Meta+Enter) in Paste mode because I'm using i3wm and the same hotkeys already assigned to "Open terminal" command. I'm sure that I'm not the only one who have this issue. Can you consider this improvement? Thanks!

When i press \ nothing happens,
It works in Python console, in ipython but not for ptpython or ptipython

I use
Python 3.4 (32 bits) om Windows 7

I unfortunately do not have a log of this but when I tried to run the following

import pickle
pickle.dump(

It started an infinite loop of exceptions that eventually required me to force kill the Python process from another terminal.

Hi,

I see there is PythonStyle class at style.py. For my dark background, the color style is not very readable.

Is there a simple way to configure that? I can try a monkey patch but...well...

Thanks,
Damien

Currently, when you have a multiline input ctrl-enter doesn't execute anymore but just adds lines (you have to press esc before to make it run).

I know this is outlined in the FAQ, but it's really annoying 😞 - can it be solved?

It'd be nice if there were a way to do basic configuration from within pt(i)python like if you change to Vi mode, or colorscheme choices and save those options. Additionally what is the option to set the code color scheme? In your example you have the UI option detailed as repl.use_ui_colorscheme('blue')

The command-history-matcher (is there a better name?) in IPython lets you do the following:

In[1]: %run <somescript>
In[2]> %ru<hit-up-arrow>  

and then it'll cycle through previous commands in In that match with "%ru", so you can quickly jump back to an earlier command

This works in IPython but doesn't work in pyipython, the ptipython behaviour is to cycle through Jedi "%ru" autocomplete commands, rather than to cycle through the command history.

Jedi has control here so the old behaviour has presumably been cut out. Possibly one approach is to let the user hit a key like Esc to stop using Jedi, then to fall back on the previous arrow-up, arrow-down behaviour?

Based on my usage patterns I'd say this is not a deal breaker (as I can still start with an empty input line and just hit arrow-up a few times)

Workaround: "ru" uses the incremental-backwards-search just as it would in IPython to find a previous command.

I am not happy with the current colorscheme of ptpython, so I tried changing the colors present in file /usr/local/lib/python2.7/dist-packages/ptpython/style.py but restarting ptpython resulted in no change. Am I doing something wrong?

IMHO, there should be an easier way to change colors.

This is not really a issue. I just don't know how to use it with Python 3. How can I use it with ptpython? Thanks in advance

Would be nice to have: be able to jump pages, not just 1 row at a time (with the arrow keys).

I'm sure there's a history behind it and a good rationale for initially adding it, but is there any possibility of getting rid of it? I'd prefer to not have to choose between clipboard access and "returning".

can I config it? I cannot find this configuration in https://github.com/jonathanslenders/ptpython/blob/master/examples/ptpython_config/config.py

Thanks for this library! I tried running ptipython immediately after install, and got this traceback after every attempted execution. Once I forcibly exited, I ran a ptpython session just fine, and when I came back to ptipython, all was well.

Hi Jonathan,

IPython startup files (http://ipython.org/ipython-doc/1/config/overview.html#startup-files) don't seem to be executed by ptipython.

For example, with a file .ipython/profile_default/hello.py that prints "Hello World":

➜  ipython
Python 2.7.5 (default, Mar  9 2014, 22:15:05)
...
Hello World
In [1]:


➜  ptipython
Python 2.7.5 (default, Mar  9 2014, 22:15:05)
... 
In [1]:

Any ideas?

Thanks,

Martin

I install with

pip install ptpython

the ptpython works ok, but when I try to run ptipython, it give the follow errors.

Hi @jonathanslenders , I love ptpython very much !

I would like to know how to support emacs' command M-x run-python ?

Before ptpython, I use Ipython for this:

   (setq
    python-shell-interpreter "ipython"
    python-shell-interpreter-args ""
    python-shell-prompt-regexp "In \\[[0-9]+\\]: "

I'm a windows with a french locale with Python 2.7. Remember, for your software to deal with non ascii characters :

• use utf8 for all files;
• use "from future import unicode_literals" for all files
• when you got an input, use your_input.decode(input_encoding). User input, sql query, file reading, downloads are all inputs.
• when you got an ouput, use your_ouput.encode(output_encoding). Terminal printing, sqlquery, writting in a file, HTTP post are all outputs.

hi, the ptpython is really awesome. the line edit was always what I want. the vi/emacs keybinds really go beyond my hope for python-shell.

the complete is beautiyf too. use the old ipython, the completion always pollute my screen too much.
but there was a problem, most time I really donot remember what the attr or function I was looking for. the old ipython give all of it, so I may choose. the ptipython give only some of it, I have to ... to
look through it. that's not good.

I request you may look at the zsh completion. It output all the output under the current cursor but not pollute the screen, and when you finish edit, it clear the completion-output.

doing import os.pa then tab doesn't give any results.

ptipython --vi --interactive=<file_name>

I cannot seem to get this working. Am I missing something or this feature does not exist?

When using ipython in ptpython mode (aka ptipython), I found the %load magic command does not work for me. The %load command is intend to load a file onto the ipython frontend so that people can edit & run it, when it runs normally in ipython, it looks like this:

But in ptipython nothing happens:

Until now most commands I used commonly works fine, only %load failed to work, if more happens, I will keep on report it here. BTW, here is a list of complete magic commands in ipython.

Versions:
Python 2.7.9
ipython==3.2.1
ptpython==0.18

ptipython ignores both /home/shane/ptpython/config.py and ~/.pythonrc.py
when run from django extensions, aka python manage.py shell_plus. There doesn't seem to be anyway to override those configurations

ptipython does not appear to have a command line option to connect to an existing kernel.

Is there anything similar to the command below that forces ptipython to use an existing kernel rather than creating a new one

ipython console --existing

I've installed it on windows 8.1 and python 2.7.9. Output is colored and everything but I don't get any autocompletion. I tried pressing TAB - is autocomplete bound to a different key?!

i just played around with emacs and vim modes after pip install
the only way i could use to submit a multiline code chunk was by going to vim nav mode
(python2.7 in a virtualenv)

This section of repr.py makes it possible to run system commands when the line is prefixed with !, but the syntax validator prevents the execution for a ! on the beginning of a line is syntax error in python.

I fixed it temporally by adding if document.text.lstrip().startswith('!'): return to the beginning of PythonValidator.validate but I am not sure if it is the right place for it.

There is no option to display a banner text when instantiating a new shell from ptpython.repl.embed.
Both IPython.terminal.embed.InteractiveShellEmbed and bpython.embed have a banner argument that I can pass a text to display to.

When typing tab for completion after "import os." I get. This might be a jedi bug but am posting it here first.

When I launch on Mac OS X 10.9.5, Python 2.7.5 I get the error below. I also get the same error in a new virtualenv.

I guess this might be a prompt_toolkit bug but I thought I'd start here.

Thanks.

Hello, I've just seen your rather awesome library. Some of it works great, a common feature that I use ("%run ") doesn't work. Maybe I'm missing something?

I'm on Ubuntu (Linux Mint 17.1 based on Ubuntu 14.04), using Python 3.4.2 (via Anaconda) with ptpython 0.4 (installed using pip today) and IPython 2.2.0. I'm using a default Ubuntu terminal.

If I type:
$ ptipython
...
In [1]: open("i
insert_pickle_into_elasticsearch.py File <- really neat autocompletion!
but if I try:
In [1]: %run i <- nothing happens, no autocompleteion
and if I continue to type the filename (e.g. "%run insert_") and try tab, nothing happens and there are no options. Does Jedi know about %run filename completion?

If I use the exclamation-mark shell convention:
In [1]: !autopep8 -i insert_
to run a shell command outside of IPython, tab completion fails here too (but if I type the full filename, autopep8 works as expected).

Both the above examples work with tab completion inside a normal IPython shell.

Sidenote - I'm not sure how the keybindings work on other platforms but if I use Ctrl-Shift-N (as noted in your README "Tab and shift+tab complete the input. In Vi-mode, you can also use Ctrl+N and Ctrl+P.") then I get a new Ubuntu Terminal (!).

I'll keep tabs on this, it looks most promising!

Hi, I am wondering why ptpython doesn't ask confirm to exit.

As you know, Ctrl+D is used for backspace on some platforms.
So, when using ptpython, I often hit Ctrl+D by mistake and ptpython exits unintentionally.

I wrote some code to prevent this as ipython does.
Does someone agree with me?

I've got a 'test' package in the top-level of my project that I'm trying to import a file from, but ptpython (and ptipython) won't let me. It seems to be picking the test package from the python standard library instead. Plain python (and plain ipython) do not have this problem. This is on python3, though I haven't tested with python2.

Steps to reproduce:

$ mkdir python-test
$ cd python-test
$ mkvirtualenv -p /usr/local/bin/python3 python-test
$ pip install ptpython
$ mkdir test
$ touch test/__init__.py
$ touch test/schema_data.py

And demonstration of the bug:

$ python
Python 3.4.1 (default, Aug 24 2014, 21:31:55)
[GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.40)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import test.schema_data
>>> quit()
$ ptpython
In [1]: import test.schema_data
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'test.schema_data'
No module named 'test.schema_data'

In [2]: import test

In [3]: test
Out[3]: <module 'test' from '/usr/local/Cellar/python3/3.4.1_1/Frameworks/Python.framework/Versions/3.4/lib/python3.4/test/__init__.py'>

I am not willing to use django-extension now.

but I would like to use ptipython for django-shell. is it possible?

I usually use pyenv, when I switch from python2 to python3, the ptpython still python2

In ptpython REPL, input:

from __future__ import division
print 1/2

got output 0.
But in standard python REPL, the output is 0.5.

Hello again. I've noticed that every time when ptpython starts it resets all custom settings, which I choose in F2 menu. I think it's a bug, isn't it?

bpython provides a pager one can use to view functions/modules
