Thank you very much! 4 | 5 | This document will help you get started with contributing code, testing (future) and filing issues. If you have any questions, feel free to reach out to [Vinayak Mehta](https://vinayak-mehta.github.io), the author and maintainer. 6 | 7 | ## Code Of Conduct 8 | 9 | The following quote sums up the **Code Of Conduct**. 10 | 11 | > Be cordial or be on your way. --Kenneth Reitz 12 | 13 | As the [Requests Code Of Conduct](https://github.com/psf/requests/blob/master/CODE_OF_CONDUCT.md) states, **all contributions are welcome**, as long as everyone involved is treated with respect. 14 | 15 | ## Your first contribution 16 | 17 | A great way to start contributing to nbcommands is to pick an issue with the [good first issue](https://github.com/vinayak-mehta/nbcommands/labels/good%20first%20issue) label. If you're unable to find a good first issue, feel free to contact the maintainer. 18 | 19 | ## Setting up a development environment 20 | 21 | To install the dependencies needed for development, you can use pip: 22 | 23 | 
 24 | $ pip install conference-radar[dev]
 25 |
26 | 27 | Alternatively, you can clone the project repository, and install using pip: 28 | 29 | 
 30 | $ pip install ".[dev]"
 31 |
32 | 33 | ## Pull Requests 34 | 35 | ### Submit a pull request 36 | 37 | The preferred workflow for contributing to nbcommands is to fork the [project repository](https://github.com/vinayak-mehta/nbcommands) on GitHub, clone, develop on a branch and then finally submit a pull request. Here are the steps: 38 | 39 | 1. Fork the project repository. Click on the ‘Fork’ button near the top of the page. This creates a copy of the code under your account on the GitHub. 40 | 41 | 2. Clone your fork of nbcommands from your GitHub account: 42 | 43 | 
 44 | $ git clone https://www.github.com/[username]/nbcommands
 45 |
46 | 47 | 3. Create a branch to hold your changes: 48 | 49 | 
 50 | $ git checkout -b my-feature
 51 |
52 | 53 | Always branch out from `master` to work on your contribution. It's good practice to never work on the `master` branch! 54 | 55 | **Protip: `git stash` is a great way to save the work that you haven't committed yet, to move between branches.** 56 | 57 | 4. Work on your contribution. Add changed files using `git add` and then `git commit` them: 58 | 59 | 
 60 | $ git add modified_files
 61 | $ git commit
 62 |
63 | 64 | 5. Finally, push them to your GitHub fork: 65 | 66 | 
 67 | $ git push -u origin my-feature
 68 |
69 | 70 | Now it's time to go to the your fork of nbcommands and create a pull request! You can [follow these instructions](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) to do this. 71 | 72 | ### Work on your pull request 73 | 74 | It is recommended that your pull request complies with the following rules: 75 | 76 | - Make sure your code follows [pep8](http://pep8.org). You should [blacken](https://github.com/psf/black) your code. 77 | 78 | - Make sure your commit messages follow [the seven rules of a great git commit message](https://chris.beams.io/posts/git-commit/): 79 | - Separate subject from body with a blank line 80 | - Limit the subject line to 50 characters 81 | - Capitalize the subject line 82 | - Do not end the subject line with a period 83 | - Use the imperative mood in the subject line 84 | - Wrap the body at 72 characters 85 | - Use the body to explain what and why vs. how 86 | 87 | - Please prefix the title of your pull request with [MRG] (Ready for Merge), if the contribution is complete and ready for a detailed review. An incomplete pull request's title should be prefixed with [WIP] (to indicate a work in progress), and changed to [MRG] when it's complete. A good [task list](https://blog.github.com/2013-01-09-task-lists-in-gfm-issues-pulls-comments/) in the PR description will ensure that other people get a better idea of what it proposes to do, which will also increase collaboration. 88 | 89 | - If contributing new functionality, make sure that you add a unit test for it, while making sure that all previous tests pass. nbcommands uses [pytest](https://docs.pytest.org/en/latest/) for testing (future). Tests can be run using: 90 | 91 | 
 92 | $ python setup.py test
 93 |
94 | 95 | ## Filing Issues 96 | 97 | [GitHub issues](https://github.com/vinayak-mehta/nbcommands/issues) are used to keep track of all issues and pull requests. Before opening an issue (which asks a question or reports a bug), please use GitHub search to look for existing issues (both open and closed) that may be similar. 98 | 99 | ### Bug Reports 100 | 101 | In bug reports, make sure you include: 102 | 103 | - Your operating system type and Python version: 104 | 105 | 
106 | import platform; print(platform.platform())
107 | import sys; print('Python', sys.version)
108 |
109 | 110 | - The complete traceback. Just adding the exception message or a part of the traceback won't help the maintainer fix your issue sooner. 111 | -------------------------------------------------------------------------------- /HISTORY.md: -------------------------------------------------------------------------------- 1 | Release History 2 | =============== 3 | 4 | master 5 | ------ 6 | 7 | 0.5.1 (2021-06-21) 8 | ------------------ 9 | 10 | - Minor documentation changes. 11 | 12 | 0.5.0 (2021-06-21) 13 | ------------------ 14 | 15 | **Improvements** 16 | 17 | - Support directories in nbgrep.

 16 | $ pip install nbcommands
 17 |
18 | 19 | or conda: 20 | 21 | 
 22 | $ conda install -c conda-forge nbcommands
 23 |
24 | 25 | ## Usage 26 | 27 | nbcommands installs the following commands which let you interact with your Jupyter notebooks without spinning up a notebook server. 28 | 29 | - `nbtouch`: Update the access and modification times of each Jupyter notebook to the current time. 30 | 31 | 
 32 |     $ nbtouch notebook1.ipynb notebook2.ipynb
33 | ![nbtouch](https://raw.githubusercontent.com/vinayak-mehta/nbcommands/master/docs/_static/nbtouch.gif) 34 | 35 | - `nbgrep`: Search for a pattern in Jupyter notebooks. 36 | 37 | 
 38 |     $ nbgrep "os" notebook1.ipynb notebook2.ipynb
 39 |     $ nbgrep "os" directory/
40 | ![nbgrep](https://raw.githubusercontent.com/vinayak-mehta/nbcommands/master/docs/_static/nbgrep.gif) 41 | 42 | - `nbhead`: Print the first 5 cells of a Jupyter notebook to standard output. 43 | 44 | 
 45 |     $ nbhead notebook1.ipynb
46 | ![nbhead](https://raw.githubusercontent.com/vinayak-mehta/nbcommands/master/docs/_static/nbhead.gif) 47 | 48 | Note: You can also specify the number of cells you want to print using the `-n` option. 49 | 
 50 |     $ nbhead -n 10 notebook1.ipynb
51 | 52 | - `nbtail`: Print the last 5 cells of a Jupyter notebook to standard output. 53 | 54 | 
 55 |     $ nbtail notebook2.ipynb
56 | ![nbtail](https://raw.githubusercontent.com/vinayak-mehta/nbcommands/master/docs/_static/nbtail.gif) 57 | 58 | Note: You can also specify the number of cells you want to print using the `-n` option. 59 | 
 60 |     $ nbtail -n 10 notebook2.ipynb
61 | 62 | - `nbcat`: Concatenate Jupyter notebooks to standard output. 63 | 64 | 
 65 |     $ nbcat notebook1.ipynb notebook2.ipynb
66 | ![nbcat](https://raw.githubusercontent.com/vinayak-mehta/nbcommands/master/docs/_static/nbcat.gif) 67 | 68 | Note: You can create a new notebook by concatenating multiple notebooks using the `-o` option. 69 | 
 70 |     $ nbcat notebook1.ipynb notebook2.ipynb -o notebook3.ipynb
71 | 72 | - `nbless`: Print a Jupyter notebook using a pager program. 73 | 74 | 
 75 |     $ nbless notebook1.ipynb
