Hi

would like to implements some new functions for the rebound which includes:

• view the answer through GUI terminal
• able to direct the user to the browser immediately to look for the link and answers
• able to record down and put it into the history

let me know what you guys think.

thank you

I am a new user of rebound, I have just installed it today ( via pip ).

I am getting this every time:

Sorry, Stack Overflow blocked our request. Try again in a minute.

I am running on Ubuntu 20.04, and I have made sure that I have proper internet connectivity.

Instead of running rebound "python main.py", it should be rebound python main.py or even rebound main.py (if we pull the language from the file extension).

Got an error attempting to install via pip. Error text is at the bottom including command line text using bash

• Operating System: CentOS Linux 7 (Core)
• Kernel: Linux 3.10.0-862.14.4.el7.x86_64
• Architecture: x86-64
• Tried installing in root directory and in named folders
• Same error message regardless of user trying to install
• Already checked google and stack overflow with no luck

$ pip install rebound-cli

Sometimes errors happen when you try to run it. Is it possible to support runtime error caught and search on the stackoverflow

Hello,
if there is anything possible like this then i'd like to contribute to this wonder full project

I have altered your code a bit for my own use, but this function is still from your source code and I don't think I caused the error. It worked two weeks ago, and I tried running it yesterday without any changes in the past two weeks and it's broken now. Did stack overflow change something breaking the search?

Using search_stackoverflow(query) with a query of "python nltk tokenize" I get an error inside the function, get_search_results(soup),

Here's an excerpt of the traceback,

 in get_search_results
title_container = result.find_all("div", class_="result-link")[0].find_all("span")[0].find_all("a")[0]                                                                                                                                   
IndexError: list index out of range         

There are values in results, and result.find_all("div", class_="result-link")[0], but result.find_all("div", class_="result-link")[0].find_all("span") returns none so index zero doesn't exist hence the error.

Did something change, if so what needs to be changed to get it working again?

It would be nice to be able to install via dnf on Fedora systems, instead of only with apt.

Instead of executing files with the rebound command, I think it would be more user-friendly to execute the file normally, get a compiler error, and then type rebound to fetch that error and display the CLI. For example, the Python workflow would be:

1. Run $ python test.py
2. Program fails and returns an error message
3. User runs $ rebound to prompt the CLI

OS: Windows 10
Python: 3.6.5

As the error in the picture shows, why is this?

Hi,

First of all, this is a really cool project!

I just started using rebound-cli, I'm on Windows and I've installed cygwin, however when I run a script i get the following error:

c:\users\fredb\appdata\local\programs\python\python38\lib\subprocess.py:844: RuntimeWarning: line buffering (buffering=1) isn't suppor

Exception in thread Thread-2:

    func(line.decode("utf-8"))
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf3 in position 13: invalid continuation byte

The script is just a simple example:

x = 5
y = 10
x += y
print(x)

I really don't understand what I'm doing wrong

Code modularity is needed. Proper classes and functions should be distributed across multiple files and the project should achieve 'Separation of Concern' design principle.

when running the program on Windows and IOS, the error will appear just like the picture above

I'm getting the same error as in #41 . Maybe stackoverflow changed again?. Browser redirect works fine.

When an item in the ListBox is selected and ENTER is pressed, the question should open in the user's default browser.

Move from Click to urwid, curses, or npyscreen.

On pressing "B" to browse the results while google chrome is the default browser, it just launch chrome with empty tab.

Maybe? idk

I am using ubuntu 20.04 LTS and python 3.8.2.
when I was testing rebound on a simple python script I got two error.

1. the first issue occurs just after the command runs, Its seems like some problem with python but I am not sure.
2. when I choose y I got the questions from StackOverflow but when I enter to see the answer it breaks and second error occurs. the output is attached below.

just kidding, this is not a real issue :)

Any solution to this?

Hi!

After I look through the code, I have a few ideas which can be put into the rebound project. This include:

• Replacing in view answer function by using lynx ( Text-based browser GUI)
• Putting create barcode function which able the user to share the solution link to other user
• Save the solution link in the history or record, so the user can check again the previous selected link

Please let me know what you guys think.

Thanks!

Hi there, I am very interested in your work and tried it on my Windows 10 box. Unfortunatly there seems to be some issues related to the close_fds working on Windows?

    process = Popen(

won't solve the problem. Something else will crash it:

I am not familar with close_fds as of writing. And to make it worse I happen to find that urwid is not supported on windows (see here, here and here)

Maybe you may declare in the README.md that the fancy program currently not supported on Windows?

I tried installing rebound by following the instructions in the readme as well as variations I compiled from looking online. After all of these I was unable to call "rebound" from the command line on a linux machine.

I tried the following installation commands:
pip install rebound-cli
pip3 install rebound-cli (with and without --user)
sudo apt-get install rebound-cli
git clone repo followed by python3 setup.py install (with and without --user)
I verified that pip and urwid are up to date.

After all of this I get the 'rebound: Command not found.' error no matter where in the directory i try to run it from

Installed rebound with pip v20.0.2. When running a simple Python file with a syntax error, produces the following -

Traceback (most recent call last):

What could be causing this?

Even though the packages are already installed it is giving errors that it requires this packages.

Scrolling works for the up/down keys but not the cursor. The scrollbar is also too close to the text.

When 'R' is pressed, the query/title should be highlighted and become editable.

We only want the error message, not the traceback.
